Network analysis has been shown to be an effective and cheap way to screen genes that are associated to diseases and chemicals. The identification of features that are used to order potentially related genes is key to do this job. Though many network models and structure based features have been proposed in the literature, they do not perform well enough for such gene prioritization task, especially...
Relational databases have been prevailing for the last two decades, with features of clear semantics and ease of use with SQL supported by the underlying theory, relational algebra. Relational databases provide good support for structural data management. However, recent development in IT brings forward big data, featuring extreme large volume and variety in data type and structures, and relational...
Based on the Technology Acceptance Model (TAM) developed from the theory of reasoned action (TRA) and social psychology research by Davis (1989), this study models the use of the Internet-based modular object-oriented dynamic learning environment (Moodle) by students of the computer science department at Ming Chuan University (MCU), Taiwan. Apart from student demographics and background information...
Low efficiency existing in the current approaches for large scale document similarity computation, to make an improvement we pinpointed a new approach based on cloud computing platform in this paper. The approach carried out document similarity computation based on traditional vector model space as well as applied MapReduce computation model to realize the parallelization of distributed inverted index...
Through applying spatial statistical analysis, Geographical Weighted Regression (GWR) model and GIS technology, this study aims at finding the relationship between the effects of various factors and spatial distribution of residential house price. The traditional regression models are reviewed firstly, the model without the consideration of spatial characteristics cannot reach very nice precision...
Due to huge number of triangles are produced when CAD model converts to graphics model that making use of the current data interface, it can't meet the requirement of real time rendering in virtual reality system. In this paper, a novel approach about CAD model's simplification and conversion was proposed. The geometry data of CAD models was simplified by reduction algorithm and then converted to...
Role is an important concept in collaboration systems and CSCW systems especially in the aspect of group awareness. This paper proposes a new group awareness model based on role by the research of role in collaboration systems and the analysis of existing awareness models. In the new proposed model, the task is decomposed into activities in order to acquire the activity graph. Then the roles are extracted...
