NYT writes about Groxis’ Grokker software “which is intended to allow personal-computer users to visually make sense of collections of thousands or hundreds of thousands of text documents.”
It uses information visualisation techniques. According to NYT, “Grokker builds a visual map of the general categories into which documents fall by using what computer software designers call metadata, which describes each Web page or document. The program currently works with the Northern Light search engine, the Amazon online catalog and as a tool for scanning a user’s own PC file collection.”
