Lighthouse: showing the way to relevant information

Lighthouse is an on-line interface for a Web-based information retrieval system. It accepts queries from a user, collects the retrieved documents from the search engine, organizes and presents them to the user. The system integrates two known presentations of the retrieved results, the ranked list and clustering visualization, in a novel and effective way. It accepts the user's input and adjusts the document visualization accordingly. We give a brief overview of the system.
