Visual User Interface for Document Retrieval Utilizing Spatial Relationships Among Document Vectors 

With the growth of the current of information such as documents, the method of selecting relevant one is more and more required. There are several ways to answer to this requirement. Visualizing information seemed to be a promising method. In this paper, we propose our user interface and algorithms. In the approach, a document-term matrix generated from a document set is decomposed usig the singular value decomposition (SVD) method. The document information is visualized on a 2-D space using the result of SVD. Users specify retrieval conditions by indicating a position on the plane. With this approach, users can easily specify retrieval conditions which will be complicated when expressed in Boolean expressions of keywords. We heve built a prototype system, and did experiments using a small set of documents.
