The team formation problem is required to find a group of individuals that can match the skills required by a collaborative task. Large-scale and comprehensive scientific research tasks need skilled experts from various fields to form a research team and work for it. This paper constructs a dataset and proposes team formation algorithms to find out research teams, which provides decision support for...
One purpose of using computational models in cognitive related researches is to use them as a tool to understand human's learning processes, especially focusing on understanding the processes of language development. Although connectionist computational models can simulate the learning process in a black-box way, understanding the inside rational relations is as important as the correlations between...
Learning analytics can give powers to teachers and learners to optimize their teaching and learning. This paper presents the design and implementation of learning analytics system for teachers and students based on a special LMS -- THEOL LMS, which is commonly used in blended learning in universities and colleges. The technical architecture of learning analytics system for teachers and students is...
In this paper, we are interested in using text mining to analyze textual data obtained from electronic social media in order to find out social concerns on crisis. In particular, we explore the temporal theme patterns in the natural catastrophe, i.e. the Yushu Earthquake, and compare the foci of the Chinese public, Chinese government and the overseas. By incorporating sources of information with a...
To improve the performance of LDPC codes, we should detect and eliminate cycles in Tanner graph of the parity-check matrix when we make LDPC codes. We improved a logic algebraic algorithm in computing entire routes between the nodes of a communication network, and found a new method of detecting cycles in Tanner graph of LDPC codes. This method applied the logic algebraic calculation rules. First...
This paper studies the functional services of the 3D visualization of urban pipe network (UPN). In accordance with the characteristics of the UPN and its demands for 3D visualization. The division of the visualization services of the 3D visualization of UPN is researched, then a structure of services division named service stack is propose in this paper, which is applicable to the 3D visualization...
