| Abstract(in English) | We have developed an document retrieval system based on our proposed method FEM (Feature Extraction Model). In this method, documents are represented as vectors on a vector space created based on FEM. This vectors space has the characteristics that it is created from the documents which are divided into different groups by human. Documents in different groups are considered to be independent from each other by human on semantic meanings. In order to improve the performance of our document retrieval system, we performed experiments to analyze the distribution characteristics of document vectors on the vector space. Based on the retrieval results, we find a method to improve the performance of the system. |
