| Abstract(in English) | A concept-based method presents feature of words by vectors. Since documents are composed of a set of words, they have a set of concept vectors of words. A center of gravity of concept vectors in documents becomes to present a feature of documents, and it can be used for search and classification problems. However, only one vector such as the center of gravity may not be enough to present their whole feature, considering a lot of words in them. It is also a problem that a vector expression is not easy to be recognized by human directly. Therefore, this paper proposes a novel method that presents features of documents by representative words of the documents. It also presents a method that extracts prototype vectors from a set of concept vectors and that derives representative words from the prototype vectors. |
