  by Yan Geng, Jianwei Ji, Bo Hu, Yingjun Ju 
  Abstract: As is well-known, the distributed photovoltaic power generation technology has been rapidly developed in recent years. The cost of distributed photovoltaic power generation is much higher than that of traditional power generation modes. Therefore, how to improve the effective use of photovoltaic cells has become a popular research direction. Based on the analysis of the characteristics of photovoltaic cells, this paper presents a mathematical model of photovoltaic cells and a maximum power point tracking algorithm based on hysteresis control and adaptive control technology variable step perturbation observation method. This algorithm can balance the control precision and control speed from the disturbance observation method and improve the tracking results significantly. Finally, the feasibility of the algorithm and the tracking effects are simulated by using Matlab/Simulink software.

• SDSAM: a service-oriented approach for descriptive statistical analysis of multidimensional spatio-temporal big data  
  by Weilong Ding, Zhuofeng Zhao, Jie Zhou, Han Li 
  Abstract: With the expansion of the Internet of Things, spatio-temporal data has been widely used and generated. The rise of big data in space and time has led to a flood of new applications with statistical analysis characteristics. In addition, applications based on statistical analysis of these data must deal with the large capacity, diversity and frequent changes of data, as well as the query, integration and visualisation of data. Developing such applications is essentially a challenging and time-consuming task. In order to simplify the statistical analysis of spatio-temporal data, a service-oriented method is proposed in this paper. This method defines the model of spatio-temporal data service and functional service. It defines a process-based application of spatio-temporal big data statistics to invoke basic data services and functional services, and proposes an implementation method of spatio-temporal data service and functional service based on Hadoop environment. Taking the highway big data analysis as an example, the validity and applicability of this method are verified. The effectiveness of this method is verified by an example. The validity and applicability of the method are verified by a case study of Expressway large data analysis. An example is given to verify the validity of the method.

• A privacy-aware and fair self-exchanging self-trading scheme for IoT data based on smart contract  
  by Yuling Chen, Hongyan Yin, Yaocheng Zhang, Wei Ren, Yi Ren 
  Abstract: With the development of the era of big data, the demand for data sharing and usage is increasing, especially in the era of Internet of things, thus putting forward a keen demand for data exchanging and data trading. However, the existing data exchanging and trading platforms are usually centralized and usersrnhave to trust platforms. This paper proposes a secure and fair exchanging and trading protocol based on blockchain and smart contract, especially, self-governance without relying centralized trust. By using the protocol, it can guarantee fairness to defend against trade cheating, and security for data confidentiality. It can also guarantee efficiency by transferring data links instead of data between data owners and data buyers. The extensive analysisrnjustified that the proposed scheme can facilitate the self-exchanging and self-trading for big data in a secure, fair and efficient manner.

• Micro-PaaS fog: container based orchestration for IoT applications using SBC  
  by Walter D.O. Santo, Rubens De Souza Matos Júnior, Admilson De Ribamar Lima Ribeiro, Danilo Souza Silva, Reneilson Yves Carvalho Santos 
  Abstract: The Internet of Things (IoT) is an emerging technology paradigm in which ubiquitous sensors monitor physical infrastructures, environments, and people in real-time to help in decision making and improve the efficiency and reliability of the systems, adding comfort and life quality to society. In this sense, there are questions concerning the limitation of computational resources, high latency and different QoS requirements related to IoT that move cloud technologies to the fog computing direction, and the adoption of light virtualised solutions, as technologies based in containers to attend to many needs of different domains. This work, therefore, has as its goal to propose and implement a micro-Paas architecture for fog computing, in a cluster of single-board computers (SBC), for orchestration of applications using containers, applied to IoT and that attend to the QoS criteria, e.g. high availability, scalability, load balance, and latency. From this proposed model, the micro-Paas fog was implemented with virtualisation technology in containers using orchestration services in a cluster built with Raspberry Pi to monitor water and energy consumption at a total cost of property equivalent to 23% of a public platform as a service (PaaS).

• Anomaly detection against mimicry attacks based on time decay modelling  
  by Akinori Muramatsu, Masayoshi Aritsugi 
  Abstract: Because cyberattackers attempt to cheat anomaly detection systems, it is required to make an anomaly detection system robust against such attempts. We focus on mimicry attacks and propose a system to detect such attacks in this paper. Mimicry attacks make use of ordinary operations in order not to be detected. We take account of time decay in modelling operations to give lower priorities to preceding operations, thereby enabling us to detect mimicry attacks. We empirically evaluate our proposal with varying time decay rates to demonstrate that our proposal can detect mimicry attacks that could not be detected by a state-of-the-art anomaly detection approach.
  Keywords: anomaly detection; mimicry attacks; time decay modelling; stream processing.

  by Georgia Garani, Nunziato Cassavia, Ilias Savvas 
  Abstract: The arrival of the big data era introduces new necessities for accommodating data access and analysis by organisations. The evolution of data is three-fold, increase in volume, variety, and complexity. The majority of data nowadays is generated in the cloud. Cloud data warehouses enhance the benefits of the cloud by facilitating the integration of cloud data in the cloud. A data warehouse is developed in this paper, which supports both spatial and temporal dimensions. The research focuses on proposing a general design for spatiobitemporal objects implemented by nested dimension tables using the starnest schema approach. Experimental results reflect that the parallel processing of such data in the cloud can process OLAP queries efficiently. Furthermore, increasing the number of computational nodes significantly reduces the time of query execution. The feasibility, scalability, and utility of the proposed technique for querying spatiotemporal data is demonstrated.

• Recommendation system based on space-time user similarity
  by Wei Luo, Zhihao Peng, Ansheng Deng 
  Abstract: With the advent of 5G, the way people get information and the means of information transmission have become more and more important. As the main platform of information transmission, social media not only brings convenience to people's lives, but also generates huge amounts of redundant information because of the speed of information updating. In order to meet the personalised needs of users and enable users to find interesting information in a large volume of data, recommendation systems emerged as the times require. Recommendation systems, as an important tool to help users to filter internet information, play an extremely important role in both academia and industry. The traditional recommendation system assumes that all users are independent. In this paper, in order to improve the prediction accuracy, a recommendation system based on space-time user similarity is proposed. The experimental results on Sina Weibo dataset show that, compared with the traditional collaborative filtering recommendation system based on user similarity, the proposed method has better performance in precision, recall and F-measure evaluation value.
  Keywords: time-based user similarity; space-based user similarity; recommendation system; user preference; collaborative filtering.
  
  
• Design and analysis of novel hybrid load-balancing algorithm for cloud data centres  
  by Ajay Dubey, Vimal Mishra 
  Abstract: In recent the pandemic scenario there is a paradigm shift, from traditional computing to internet-based computing. Now is the time to store and compute the data in the cloud environment. The Cloud Service Providers (CSPs) establish and maintain a huge shared pool of computing resources that provide scalable and on-demand services around the clock without geographical restrictions. The cloud customers are able to access the services and pay according to the accession of resources. When millions of users across the globe connect to the cloud for their storage and computational needs, there might be issues such as delay in services. This problem is associated with load balancing in cloud computing. Hence, there is a need to develop effective load-balancing algorithms. The Novel Hybrid Load Balancing (NHLB) algorithm proposed in this paper manages the load of the virtual machine in the data centre. This paper is focused on certain problems such as optimisation of performance, maximum throughput, minimisation of makespan, and efficient resource use in load balancing. The NHLB algorithm is more efficient than conventional load-balancing algorithms with reduced completion time (makespan) and response time. This algorithm equally distributes the tasks among the virtual machines on the basis of the current state of the virtual machines and the task time required. The paper compares the result of proposed NHLB algorithm with dynamic load-balancing algorithm and honeybee algorithm. The result shows that the proposed algorithm is better than the dynamic and honeybee algorithms.

• Cloud infrastructure planning considering the impact of maintenance and self-healing routines over cost and dependability attributes  
  by Carlos Melo, Jean Araujo, Jamilson Dantas, Paulo Pereira, Felipe Oliveira, Paulo Maciel 
  Abstract: Cloud computing is the main trend regarding internet service provision. This paradigm, which emerged from distributed computing, gains more adherents every day. For those who provide or aim at providing a service or a private infrastructure, much has to be done, costs related to acquisition and implementation are common, and an alternative to reduce expenses is to outsource maintenance of resources. Outsourcing tends to be a better choice for those who provide small infrastructures than to pay some employees monthly to keep the service life cycle. This paper evaluates infrastructure reliability and the impact of outsourced maintenance over the availability of private infrastructures. Our baseline environments focus on blockchain as a service; however, by modelling both service and maintenance routines, this study can be applied to most cloud services. The maintenance routines evaluated by this paper encompass a set of service level agreements and some particularities related to reactive, preventive, and self-healing methods. The goal is to point out which one has the best cost-benefit for those with small infrastructures, but that still plans to provide services over the internet. Preventive and self-healing repair routines provided a better cost-benefit solution than traditional reactive maintenance routines, but this scenario may change according to the number of available resources that the service provider has.

• Edge computing and its boundaries to IoT and Industry 4.0: a systematic mapping study  
  by Matheus Silva, Vinícius Meyer, Cesar De Rose 
  Abstract: In the last decade, cloud computing transformed the IT industry, allowing companies to execute many services that require on-demand availability of computational resources with more flexible provisioning and cost models, including the processing of already growing data volumes. But in the past few years, other technologies such as internet of things and the digitised industry known as Industry 4.0 have emerged, increasing data generation even more. The large amounts of data produced by user-devices and manufacturing machinery have made both industry and academia search for new approaches to process all this data. Alternatives to the cloud centralised processing model and its inherent high latencies have been studied, and edge computing is being proposed as a solution to these problems. This study presents a preliminary mapping of the edge computing field, focusing on its boundaries to the internet of things and Industry 4.0. We began with 219 studies from different academic databases, and after the classification process, we mapped 90 of them in eight distinct edge computing sub-areas and nine categories based on their main contributions. We present an overview of the studies on the edge computing area, which evidences the main concentration sub-areas. Furthermore, this study intends to clarify the remaining research gaps and the main challenges faced by this field, considering the internet of things and Industry 4.0 demands.
  Keywords: edge computing; internet of things; Industry 4.0; systematic mapping.
  
  
• Data collection in underwater wireless sensor networks: performance evaluation of FBR and epidemic routing protocols for node density and area shape  
  by Elis Kulla 
  Abstract: Data collection in Underwater Wireless Sensor Networks (UWSN) is not a trivial problem, because of unpredictable delays and unstable links between underwater devices. Moreover, when nodes are mobile, continuous connectivity is not guaranteed. Therefore, data collection in UWSN Node scarcity and movement patterns create different environments for data collection in underwater communication. In this paper, we investigate the impact of the area shape and node density in UWSN, by comparing Focused Beam Routing (FBR) and Epidemic Routing (ER) protocols. Furthermore, we also analyse the correlation between different performance metrics. From simulation results we found that when using FBR, delay and delivery probability slightly decrease (2.1%) but the overhead ratio decreases noticeably (46.9%). The correlation between performance metrics is stronger for square area shape, and is not noticeable for deep area shape.
  Keywords: underwater wireless sensor networks; focused beam routing; delay tolerant network; area shape; node density; data collection.
  
  
• Joint end-to-end recognition deep network and data augmentation for industrial mould number recognition  
  by RuiMing Li, ChaoJun Dong, JiaCong Chen, YiKui Zhai 
  Abstract: With the booming manufacturing industry, the significance of mould management is increasing. At present, manual management is gradually eliminated owing to need for a large amount of labour, while the effect of a radiofrequency identification (RFID) system is not ideal, which is limited by the characteristics of the metal, such as rust and erosion. Fortunately, the rise of convolutional neural networks (CNNs) brings down to the solution of mould management from the perspective of images that management by identifying the digital number on the mould. Yet there is no trace of a public database for mould recognition, and there is no special recognition method in this field. To address this problem, this paper first presents a novel data set aiming to support the CNN training. The images in the database are collected in the real scene and finely manually labelled, which can train an effective recognition model and generalise to the actual scenario. Besides, we combined the mainstream text spotter and the data augmentation specifically designed for the real world, and found that it has a considerable effect on mould recognition.

• An SMIM algorithm for reduction of energy consumption of virtual machines in a cluster  
  by Dilawaer Duolikun, Tomoya Enokido, Makoto Takizawa 
  Abstract: Applications can take advantage of virtual computation services independently of heterogeneity and locations of servers by using virtual machines in clusters. Here, a virtual machine on an energy-efficient host server has to be selected to perform an application process. In this paper, we newly propose an SMI (Simple Monotonically Increasing) estimation algorithm to estimate the energy consumption of a server to perform application processes and the total execution time of processes on a server. We also propose an SMIM (SMI Migration) algorithm to make a virtual machine migrate from a host server to a guest server to reduce the total energy consumption of the servers by estimating the energy consumption in the SMI algorithm. In the evaluation, we show the energy consumption of servers in a cluster can be reduced in the SMIM algorithm compared with other algorithms.

• FIAC: fine-grained access control mechanism for cloud-based IoT framework  
  by Bhagwat Prasad Chaudhury, Kasturi Dhal, Srikant Patnaik, Ajit Kumar Nayak 
  Abstract: Cloud computing technology provides various computing resources on demand to the user on pay per use basis. The users use the services without the need for establishment and maintenance costs. The technology fails in terms of its usage owing to confidentiality and privacy issues. Access control mechanisms are the tools to prevent unauthorised access to remotely stored data. CipherText Policy Attribute-based Encryption (CPABE) is a widely used tool for facilitating authorised users to access the remotely stored encrypted data with fine-grained access control. In the proposed model FIAC (Fine-Grained Access Control Mechanism for cloud-based IoT Framework ), the access control mechanism is embedded in the cloud-based application to measure and generate a report on the air quality in a city. The major contribution of this work is the design of three algorithms all of which are attribute based: key generation algorithm, encryption and decryption algorithms. Only authorised users can view it to take appropriate action plans. Carbon dioxide concentrations, dust, temperature, and relative humidity are the parameters that we have considered for air quality. To enhance the security of the cloud-based monitoring system, we have embedded a security scheme, all of which are attribute based. Further, the computation time of the model is found to be encouraging so that it can be used in low power devices. The experimental outcomes establish the usability of our model.

• University ranking approach with bibliometrics and augmented social perception data  
  by Kittayaporn Chantaranimi, Rattasit Sukhahuta, Juggapong Natwichai 
  Abstract: Typically, universities aim to achieve a high position in ranking systems for their reputation. However, self-evaluating rankings could be costly because the indicators are not only from bibliometrics, but also the results of over a thousand surveys. In this paper, we propose a novel approach to estimate university rankings based on traditional data, i.e., bibliometrics, and non-traditional data, i.e., Altmetric Attention Score, and Sustainable Development Goals indicators. Our approach estimates subject-areas rankings in Arts & Humanities, Engineering & Technology, Life Sciences & Medicine, Natural Sciences, and Social Sciences & Management. Then, by using Spearman rank-order correlation and overlapping rate, our results are evaluated by comparing with the QS subject ranking. From the result, our approach, particularly the top-10 ranking, performed estimating effectively and then could assist stakeholders in estimating the university's position when the survey is not available.

• Strongly correlated high utility item-sets recommendation in e-commerce applications using EGUI-tree over data stream  
  by P. Amaranatha Reddy, M. H. M. Krishna Prasad, S. Rao Chintalapudi 
  Abstract: The product recommendation feature helps the customers to select the right items in e-commerce applications. Grounded on a similar kind of customer purchase history previously, it recommends the items to the customers. The customers may or may not choose from the recommended items list. Suppose the customers like and purchase them, it is added advantage to both the buyers and the sellers. In sellers' sales, they get the benefit of an increase; in addition, the buyers too can save their time to search. Thus, a recommendation system must be designed so that the suggested items have High Utility (HU) and strong correlation to meet such requirements. High profit is exhibited by the HU items and the strongly correlated items have more probability of selection. As these measurements have significant roles in the business process, both of those measurements of items needed to be taken care. Here, since up-to-date data in the data stream are got, the stream of purchase transactions is mined using the sliding window technique to extract such item-sets.

• WHBO: War honey badger optimisation enabled load balancing in IoT-cloud-fog computing  
  by M.N. Babitha, M. Siddappa 
  Abstract: Load balancing scheme attains minimal time for processing and has minimal response time. A main concept of load balancing is tasks are allocated and reallocated between available resources. In this work, IoT-cloud-fog is simulated initially and then, tasks are allocated to VM in round robin manner for each region. A workload of VM is computed based on memory, bandwidth, CPU and migration time. If the computed workload is greater than a threshold value, load balancing is conducted. The load balancing is performed by tasks allocation from user to VMs in a region on basis of resource constraints optimally utilizing proposed WHBO and then the tasks are assigned to other underloaded VMs. The objectives considered are energy consumption, predicted resources, execution time, cost, trust, resource utilization and bandwidth. Here, the resources are predicted employing DQN. Moreover, devised WSOHB is newly introduced by combining WSO and HBA.

• A model for simulating residential location choices of working women considering compact city planning  
  by Kaoru Fujioka 
  Abstract: In Japan, the aging of the population and declining birthrate have led to a shortage of workers, making it necessary to consider more diverse work styles and create new urban structures that accommodate a variety of lifestyles. In this study, we developed a model to simulate the residential location choices of working women in the context of compact city planning. Our results showed that land costs can impact the compactization of cities and that housing expenses and preferences for location are important factors in residential location decisions. We also found that differences in overall residential trends were based on housing expenses and preferences for location, rather than household type. Our model highlights the importance of addressing land costs and household preferences in compact city planning for working women and other diverse households.

  Abstract: With the development of signal processing technologies, full-duplex wireless transmission has attracted attention as a promising method to increase network throughput. In this study, we discuss a new Medium Access Control (MAC) protocol designed to improve throughput by inducing parallel transmissions by neighbors of an initial full-duplex transmitter (initiator). In our proposed approach, an initiator informs candidate terminals of an opportunity for parallel transmissions to avoid interference between transmissions. We also present the results of computer simulations to demonstrate that our proposed method may be expected to improve throughput performance effectively even under network conditions that also involve traditional terminals performing half-duplex wireless communication.

• A novel scheme of classification for non-functional requirements using CNN with LSTM and GRU new hidden layer  
  by Devendra Kumar, Anil Kumar Solanki, Laxman Singh 
  Abstract: In the software development process, finding the requirement before developing the software is essential. There are two kinds of the requirement in software development: functional requirement and Non-Functional Requirement (NFR). For functional requirement a lot of research work has been done, but for NFR very limited research has been done. NFR is critical for software development because it specifies quality and constraints of the system. A critical aspect of analysing NFRs is domain knowledge, expertise, and significant human effort, since NFRs are written in natural language. To automate the software requirement classification, many ML-based techniques are being developed. In this paper, the proposed CNN model obtained the accuracy, recall, precision, and F1-score of 0.984, 0.99, 0.984, 0.984, and 0.989, 0.99, 0.988, 0.999, performance respectively for BOWs and TF-IDF feature selection techniques. The proposed performance varies with respect to the number of requirement class, but the proposed CNN techniques performed better than the existing machine learning techniques.

• Computational intelligence system applied to plastic microparts manufacturing process  
  by Andrés Felipe Rojas Rojas, Miryam Liliana Chaves Acero, Antonio Vizan Idoipe 
  Abstract: In the search for knowledge and technological development, there has been an increase in new analysis and processing techniques closer to human reasoning. With the growth of computational systems, hardware production needs have also increased. Parts with millimetric to micrometric characteristics are required for optimal system performance, so the demand for injection moulding is also increasing. Injection moulding process in a complex manufacturing process because mathematical modelling is not yet established: therefore, to address the selection of correct values of injection variables, computational intelligence can be the solution. This article presents the development of a computational intelligence system integrating fuzzy logic and neural network techniques with CAE modelling system to support injection machine operators, in the selection of optimal machine process parameters to produce good quality microparts using fewer processes. The tests carried out with this computational intelligent system have shown a 30% improvement in the efficiency of the injection process cycles.

• An optimal channel state information feedback design for improving the spectral efficiency of device-to-device communication  
  by Prabakar Dakshinamoorthy, Saminadan Vaitilingam 
  Abstract: This article introduces a regularised zero-forcing (RZF) based channel state information (CSI) feedback design for improving the spectral efficiency of device-to-device (D2D) communication. This proposed method exploits conventional feedback design along with the optimised CSI in regulating the communication flows in the communicating environment. The codebook-dependent precoder design improves the rate of feedback by streamlining time/frequency dependent scheduling. The incoming communication traffic is scheduled across the available channels by pre-estimating their adaptability and capacity across the underlying network. This helps to exchange partial channel information between the communicating devices without the help of base station services. These features reduce the transmission error rates to achieve better sum rate irrespective of the distance and transmit power of the devices.

• Fuzzy forests for feature selection in high-dimensional survey data: an application to the 2020 US Presidential Election  
  by Sreemanti Dey, R. Michael Alvarez 
  Abstract: An increasingly common methodological issue in the field of social science is high-dimensional and highly correlated datasets that are unamenable to the traditional deductive framework of study. Analysis of candidate choice in the 2020 Presidential Election is one area in which this issue presents itself: in order to test the many theories explaining the outcome of the election, it is necessary to use data such as the 2020 Cooperative Election Study Common Content, with hundreds of highly correlated features. We present the fuzzy forests algorithm, a variant of the popular random forests ensemble method, as an efficient way to reduce the feature space in such cases with minimal bias, while also maintaining predictive performance on par with common algorithms such as random forests and logit. Using fuzzy forests, we isolate the top correlates of candidate choice and find that partisan polarisation was the strongest factor driving the 2020 Presidential Election.

• An efficient intrusion detection system using unsupervised learning AutoEncoder  
  by N.D. Patel, B.M. Mehtre, Rajeev Wankar 
  Abstract: As attacks on the network environment are rapidly becoming more sophisticated and intelligent in recent years, the limitations of the existing signature-based intrusion detection system are becoming more evident. For new attacks such as Advanced Persistent Threat (APT), the signature pattern has a problem of poor generalisation performance. Research on intrusion detection systems based on machine learning is being actively conducted to solve this problem. However, the attack sample is collected less than the normal sample in the actual network environment, so it suffers a class imbalance problem. When a supervised learning-based anomaly detection model is trained with these data, the results are biased toward normal samples. In this paper, AutoEncoder (AE) is used to perform single-class anomaly detection to solve this imbalance problem. The experimental evaluation was conducted using the CIC-IDS2017 dataset, and the performance of the proposed method was compared with supervised models to evaluate the performance

• Optimal attack detection using an enhanced machine learning algorithm  
  by Reddy Saisindhutheja, Gopal K. Shyam, Shanthi Makka 
  Abstract: As computer network and internet technologies advance, the importance of network security is widely acknowledged. Network security continues to be a substantial challenge within the cyberspace network. The Software-as-a-Service (SaaS) layer describes cloud applications where users can connect using web protocols such as hypertext transfer protocol over transport Layer Security. Worms, SPAM, Denial-of-service (DoS) attacks or botnets occur frequently in the networks. In this light, this research intends to introduce a new security platform for SaaS framework, which comprises two major phases: 1) optimal feature selection and (2) classification. Initially, the optimal features are selected from the dataset. Each dataset includes additional features, which further leads to complexity. A novel algorithm named Accelerator updated Rider Optimisation Algorithm (AR-ROA), a modified form of ROA and Deep Belief Network (DBN) based attack detection system is proposed. The optimal features that are selected from AR-ROA are subjected to DBN classification process, in which the presence of attacks is determined. The proposed work is compared against other existing models using a benchmark dataset, and improved results are obtained. The proposed model outperforms other traditional models, in aspects of accuracy (95.3%), specificity (98%), sensitivity (86%), precision (92%), negative predictive value (97%), F1-score (86%), false positive ratio (2%), false negative ratio (10%), false detection ratio (10%), and Matthews correlation coefficient (0.82%).

• Enhanced speculative approach for big data processing using BM-LOA algorithm in cloud environment  
  by Hetal A. Joshiara, Chirag S. Thaker, Sanjay M. Shah, Darshan B. Choksi 
  Abstract: In the event that one of the several tasks is being allocated to an undependable or jam-packed machine, a hugely parallel processing job can be delayed considerably. Hence, the majority of the parallel processing methodologies, namely (MR), have espoused diverse strategies to conquer the issue called the straggler problem. Here, the scheme may speculatively introduce extra copies of a similar task if its development is unnaturally slow when an additional idling resource is present. In the strategies-centred processes, the dead node is exhibited. the (RT) along with backup time of the slow task is assessed. The slow task is rerun with the aid of BM-LOA subsequent to the evaluation. In both heterogeneous and homogeneous environments, the proposed approach is performed. Centred on the performance metrics, the proposed research techniques performance is scrutinised in experimental investigation. Thus, when weighed against the other approaches, the proposed technique achieves superior performance.

• Importance of big data for analysing models in social networks and improving business  
  by Zhenbo Zang, Honglei Zhang, Hongjun Zhu 
  Abstract: The digital revolution is the build-up of many digital advances, such as the network phenomena transformation. To increase business productiveness and performance, participatory websites that allow active user involvement and the intellectual collection became widely recognized as a value-added tool organization of all sizes. However, it has lacked an emphasis on business and management literature to promote profitable business-to-business (b2b). User knowledge is a way to consider the kinds of search ions that big data can use. The use of social media data for analysing business networks is a promising field of research. Technological advances have made the storage and analysis of large volumes of data commercially feasible. Big information represents many sources of organised, half-structured, and unstructured data in real-time. Big data is a recent phenomenon in the computing field, which involves technological or market study. The management and research of a vast network provide all companies with significant advantages and challenges. The volume of information floating on social networks grows every day and, if processed correctly, provides a rich pool of evidence.

• Study on the economic consequences of enterprise financial sharing model  
  by Yu Yang, Zecheng Yin 
  Abstract: Using enterprise system ideas to examine the business process requirements of firms, the Financial Enterprise Model (FEM) is a demanding program. This major integrates finance, accounting, and other critical business processes. Conventional financial face difficulties due to low economic inclusion, restricted access to capital, lack of data, poor R&D expenditures, underdeveloped distribution channels, and so on. This paper mentions making, consuming, and redistributing goods through collaborative platform networks. These three instances highlight how ICTs (Information and Communication Technologies) can be exploited as a new source of company innovation. The sharing economy model can help social companies solve their market problems since social value can be embedded into their sharing economy cycles. As part of the ICT-based sharing economy, new business models for social entrepreneurship can be developed by employing creative and proactive platforms. Unlike most public organizations, double-bottom-line organizations can create social and economic advantages. There are implications for developing and propagating societal values based on these findings.
