In this study, we analyze the phenomenon of 'fake news' spreading in the Internet. In recent years, the number of fake news and misinformation spreading cases increased. We analyze vaccine-related fake news spreading in Twitter and discover techniques used by the participants of fake news spreading. We present a simulation game designed to teach the public about the techniques behind fake news spreading.

Nowadays, educational donation plays an important role in the development of education. Since the effectiveness of education donations is affected by many factors, this paper presents a model to find an optimal investment strategy by processing bigdata. First, a criterion of investment is established by using TOPSIS method. Based on the criterion, schools worth investing are selected through SVM method. After determining return of investment and prosperity index with method of Principal Component analysis and data Envelopment analysis, this model can allocate funds to invest institutions properly for the next five years, taking both indexes into consideration. Finally, this paper extends the model to make it more realistic.

Topic modeling methods, such as latent Dirichlet allocation (LDA), are successfully applied in a number of computational linguistics applications. This paper presents a new approach to topic modeling within a new domain other than linguistic analysis. We present a pilot study where an LDA model is applied to an online community rather than the textual contents they produced using the idea that a user in an article is analogous to a word in a document within the context of the LDA model. We also propose a method for determining polarity using positive (+) and negative (-) signs regarding topics. As a result, each user has a topic score whose absolute value is equal to the topic distribution learned from topic modeling, and its sign indicates the polarity on that specific subject. We demonstrate the effectiveness of our proposed approach with experimental results, which provide opportunities to apply the LDA model to targets other than lexical elements.

Additive technologies are expected to revolutionize manufacturing across almost every industry, but there is a sizable gap between the current state of the technology and the maturity required for it to achieve widespread adoption. Advanced analytics are required to improve the reliability and repeatability of additive manufacturing, and those analytics require data. Large volumes of multimodal data are generated and used throughout the additive manufacturing lifecycle, from material design to part design and simulation, part printing to post-processing and inspection. To capture and link that diverse bigdata together, we have designed and developed a federated multimodal bigdata storage and analytics platform comprised of three tiers-a distributed polyglot data storage and analysis tier with different repositories for different data structures, a metadata knowledge graph tier for modeling the data and their relationships across the various repositories, and a user interface tier for visualizing, exploring and invoking analytics on the data. The platform has been used to integrate a collection of previously disparate steps to optimize the process parameters used to build a new additive material, enabling materials scientists and other non-software experts to capture, visualize and analyze the requisite data through a single user interface.

As the basis for the production, planning and control in enterprises, inventory management provides an essential foundation for the production management and cost control of the enterprises. In this paper, the inventory in the bigdata logistics is controlled effectively based on the error correction model, which has implemented the construction of the bigdata logistics inventory control model. The significant contributions of the applications of bigdata in multiple aspects of the logistics linkage network to the development of the enterprise inventory management are summarized. In the summary of the advantages in the bigdata applications, the problems identified are studied and analyzed. The effect of the logistics inventory control put forward in this paper is analyzed through the inventory in the bigdata logistics. analysis of the feasibility and practicality is carried out. The research results show that the error correction model can be used to obtain relatively good modeling and the generalization capacity is also relatively strong.

Higher education institutions already accumulated enormous volumes of bigdata associated with student success, enrolment, professors, educational programs, educational computer systems, economics, etc., that potentially can be used for sustainable development analysis. However, their practical applications in higher education institutions are remained relatively rare because of complexity in the subject domain and lack of a methodological base to reuse some effective previously created models. This paper introduces an approach to incorporate bigdata into higher education sustainabiity analysis and reduce the complexity of the subject domain infrastructure by using a set of formalized systems. Within this approach, a simulation umbrella is used as a united methodological base to combine bigdata and sustainabiity analysis implementation. To illusfrate how the proposed approach works, a simulation case-study associated with a USA young fast-growing higher education institution included in the paper.

Topic modeling has been an important field in natural language processing (NLP) and recently witnessed great methodological advances. Yet, the development of topic modeling is still, if not increasingly, challenged by two critical issues. First, despite intense efforts toward nonparametric/post-training methods, the search for the optimal number of topics K remains a fundamental question in topic modeling and warrants input from domain experts. Second, with the development of more sophisticated models, topic modeling is now ironically been treated as a black box and it becomes increasingly difficult to tell how research findings are informed by data, model specifications, or inference algorithms. Based on about 120,000 newspaper articles retrieved from three major Canadian newspapers (Globe and Mail, Toronto Star, and National Post) since 1977, we employ five methods with different model specifications and inference algorithms (Latent Semantic analysis, Latent Dirichlet Allocation, Principal Component analysis, Factor analysis, Nonnegative Matrix Factorization) to identify discussion topics. The optimal topics are then assessed using three measures: coherence statistics, held-out likelihood (loss), and graph-based dimensionality selection. Mixed findings from this research complement advances in topic modeling and provide insights into the choice of optimal topics in social science research.

In bigdata environment, due to the rapid clustering and data forwarding of data in the multi-path transmission link layer, it is vulnerable to network virus implantation and intrusion. By quantifying the network risk security situation in bigdata environment, improve the ability to withstand risks. A quantitative analysis and prediction algorithm of network risk security situation in bigdata environment based on bigdata fuzzy C-means clustering and network intrusion information spectrum feature extraction is proposed. The quantitative analysis model of network risk security situation under the environment of bigdata is constructed. bigdata fuzzy C-means clustering algorithm is used to cluster and evaluate the statistical characteristic information data of network intrusion. The high-order spectrum characteristics of bigdata are analyzed quantitatively by extracting the security situation of network risk, and the quantitative assessment of network risk security situation and the detection of network intrusion are realized. The simulation results show that the algorithm has high accuracy in evaluating the situation of network risk security, and realizes the quantitative assessment and intrusion detection of network risk security situation in different scenarios, and improves the ability of the network to resist network intrusion under the environment of bigdata.
