There are two important problems worth conducting research in the fields of personalized information services based on user model. One is how to get and describe user personal information, i.e. building user model, the other is how to organize the information resources, i.e. document clustering. It is difficult to find out the desired information without a proper clustering algorithm. Several new...
The digitization of books can not only provide a electronic way to read but also make it possible to establish information systems via information extraction and correlation. This paper proposed a new approach that build up a traditional Chinese medicine (TCM) diagnosis system by extracting information from textbooks. First of all, we design a semantic ontology which can achieve targeted and precise...
Digital libraries have shouldered the mission of preserving and spreading human culture in the era of information. However, knowledge extraction for digital libraries is not well studied, and that holds back the role promotion of digital libraries from information collector to knowledge provider. This paper presents an ontology-based approach, which extracts detailed attributes of Traditional Chinese...
Watershed transformation is a common technique for image segmentation. However, its use for medical image segmentation has been limited particularly due to over-segmentation. In response to the characteristics of medical image, especially the contour extraction from the MRI (magnetic resonance imaging) brain image, this paper proposes an improved method in order to overcome the drawbacks. Firstly,...
The concept of brain-computer interface (BCI) has emerged over the last three decades as a promising alternative to the existing interface methods. However the BCI framework generally spoken only emphasizes on the aspects of BCI signal processing, lacking of the function of visualization and virtual reality (VR) feedback. This paper designs a general and extendable framework which has the ability...
Electrodes connection on the scalp needs to apply gel or paste on the scalp and fit EEG-cap on the head and this procedure also needs to deal with the hair on it. By comparison, to fit EEG electrodes on the forehead area is much easier because there is no hair on it. If correlations of the EEGs generated from the forehead area are high with respect to EEGs from the sensorimotor area, it is then possible...
Walking stability is the main reason for leading to falls for people, especially for elders. But there are much more features related with walking so that we cannot understand which features are more important than others to contribute the walking stability. Almost all of researches focused on some specific features but didn't present any reasons for that. Therefore, the Dynamic Time Warping (DTW)...
With the dramatic increase of information on Web, text filtering is a key technology in content processing. Now more and more researchers know that filter must be based on the meaning of the word but not on a specific sequence of signs, so they pay more and more attention on filtering method based on semantics recently. However, the usability of these methods is inconvenient up to now, because they...
More and more researchers have been interested in walking analysis for health management of elderly people. Before understanding pathological gait, it is necessary to understand normal gait, since this provides a quantitative standard to judge or evaluate the gait of a patient. A starting point to do this is to study the relationship between walking features and ages. For this purpose, this paper...
