In this paper, a data mining approach for query refinement is proposed using Association Rules (ARs) among keywords being extracted from a document database. When a query is under-specified or contains ambiguous keywords, a set of association rules will be displayed to assist the user to choose additional keywords in order to refine his/her original query. To the best of our knowledge, no reported...
We perform a research about Japanese sightseeing guidance question answering (QA) system. In this domain Web information retrieval approach is always being used. However for the Web information retrieval, Japanese unknown place word detection needs to be considered. Some famous places are known very well, such as "Kinkaku-ji", it can be recognized by morphological analysis. However, the...
Previous research revealed an interaction between eye gaze and emotional facial expressions. There are also evidences that elevated levels of trait anxiety are associated with an increased ability to accurately recognize facial expressions of fear, and enhanced cueing effect of eye gaze of fearful faces. In this study, we investigate the relationship between facial expression and gaze processing with...
A fair non-repudiation security protocol can provide non-repudiation proof for two parts of the exchange at the same time, or both get nothing. But many protocols performed weak in logical analysis. In this paper, a group of new protocols(with 3 sub-protocols) with off-line The Third Party(TTP) are presented. We analysis them with a new Kailar logic analytical method. Finally, the proposed protocols...
This paper aims to locate a tag position inside the building by using low cost device with minimal location error. The enhancement approach with received signal strength indication (RSSI) technique is proposed to achieve the target. In this paper, after introducing the existing LANDMARC system, we try to construct the relationship between RSSI and distance from reader to tag by experiment. Finally,...

The effects of gaze direction on the perception of facial expressions have been getting more and more attention from psychologists, but their implication for facial expression recognition in computer science is neglected. In the present psychological study, we investigated the effects of gaze direction on the perception of facial expressions, and focused on the role of social dominance of facial expressions...
