Dynamic Visualization of Hubs and Authorities during Web Search

摘要

The Information Retrieval Visualizer (IRV) is a web-based retrieval system that provides the user with dynamic visualizations of search results. It combines well-known techniques of information retrieval, including stemming, keyword matching, and cosine similarity, with the new and relatively successful hubs and authority approach for describing Web document relevance based on a document's relationship to other documents. The system develops a new and unique approach to document visualization that encodes these metrics in a single visual representation. This new, easily scannable representation, allows the user to interact with search results as the scope of search is expanded dynamically across the Web.
