Abstract:
|
This report describes an implementation of a cluster based
information retrieval system with statistical ranking facilities, ANIRS. ANIRS uses the vector space model to represent the document database. In this model, the database is defined by a document by term, D, matrix. In this matrix, each row represents the terms in a single document and each column represents the documents that contain a single term.
In ANIRS, two matching methodologies are allowed: a full database search and a cluster based search. The system uses a
natural language query interface. It incorporates suffix
stripping for term conglomeration. Two methods of query
refinement are used: relevance feedback and document seed
searching. Cluster browsing, the ability to look at all the
documents in a single cluster, is also implemented. |
