Visual support for information retrieval based on linear algebra

This paper presents our prototype visualization system for text information retrieval and its technical details on algorithm design. This system supports the user to construct an initial query type and further refine the query by visual interaction. Visualization of text information retrieval is one of the attractive research areas in the information retrieval. There are many mathematical algorithms used for information retrieval. In this paper, we will investigate an approach to construct visual representations based on Singular Value Decomposirion (SVD) of matrix and implement visual interfaces using Java. Experimental results show the feasibility of the proposed approach, The ideas in this approach can also be helpful in other visualization environments
