Research Note: A Cooperative Discussion Support System through Visualization of Participants' Contributions to a Discussion

This paper proposes a new discussion support system. The proposed system supports participants in cooperative discussions, evaluates the contributions of participants to a discussion, and visualizes the contribution points in a ranking list. We have developed the proposed system and evaluated it in an evaluation experiment. Experimental results show that the proposed system supports cooperative discussions.     

An Approach to Security for Unstructured Big Data

Security of Big Data is a huge concern. In a broad sense, Big Data contains two types of data: structured and unstructured. Providing security to unstructured data is more difficult than providing security to structured data. In this paper, we have developed an approach to provide adequate security to unstructured data by considering types of data and their sensitivity levels. We have reviewed the different analytics methods of Big Data to build nodes of different types of data. Each type of data has been classified to provide adequate security and enhance the overhead of the security system. To provide security to a data node, and a security suite has been designed by incorporating different security algorithms. Those security algorithms collectively form a security suite which has been interfaced with the data node. Information on data sensitivity has been collected through a survey. We have shown through several experiments on multiple computer systems with varied configurations that data classification with respect to sensitivity levels enhances the performance of the system. The experimental results show how and in what amount the designed security suite reduces overhead and increases security simultaneously.
