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.
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. Digital Library, Information Retrieval, Information Filtering, Visualisation 1. Recently, much attention has been paid to visual user interface for document retrieval. This is mainly because such user interface is deemed to be a promising method to overcome the limitations of systems using keyword interface.
