Text Categorization (TC) is an important component in many information organization and information management tasks. In many TC applications, the case-base grows at a fast rate and this causes inefficiency in the case retrieval process. Using Case-Base Maintenance learning via the GC (Generalization Capability) algorithm, which can reduce the case number into KNN algorithm, can improve efficiency...
To deal with the problem of too many answers returned from a Web database in response to a user query, this paper proposes a novel categorization approach which takes advantages of the user contextual preferences to construct a navigational tree in order to reduce the information overload. Based on the user original query, we first speculate how much the user cares about each attribute in the specified...
Literature-based discovery is linking two or more literature concepts that have heretofore not been linked (i.e., disjoint), in order to produce novel, interesting, plausible, and intelligible knowledge. Cluster analysis is the core of literature-based discovery. This paper proposes an improved fuzzy c means (FCM) algorithm based on the analysis of existing clustering analysis of literature-based...
The system of arms information extraction based on the ontology, consists of two parts: knowledge base, processing program. It realizes the arms category determination based on text categorization, and realizes the arms object determination based on named entity recognition. It realizes the information extraction according to information extraction rules based on syntax and semantic constraint. It...
The problem of similarity measure for time series has attracted considerable research interest. Most of the recently used algorithms utilize the Dynamic Time Warping (DTW) distance for measuring the similarity of time series, in various areas such as science, medicine, industry, and finance. DTW is a considerably more robust distance measure for time series, which allows similar shapes to match even...
Sequential pattern mining is an important and useful tool with broad applications, such as analyzing customer purchase behavior, recommending services to customers, and so on. It is challenging since explosive number of subsequences need to be examined and both the memory and computational cost are becoming extremely expensive when the sequence database grows huge. Many previous algorithms developed...
Performance assessment has become an effective means to assess the research and development (R&D) staff scientifically and reasonably. Taken M Biological Research Institute as an example of the performance assessment system, different key performance indicators(KPI) are proposed according to the different job responsibilities in different departments. By using analytical hierarchy process and...
This paper applied Multi-Agent to E-commerce personalized Recommender System, and designed E-commerce personalized Recommender System based on Multi-Agent, namely, MAPRS. Off-line recommendation and on-line hybrid recommendation are used to construct the core recommender model under the intelligent control. The paper presents the function and design ideas of various components of the system.
