Abstract

Recently we proposed a new context-based information retrieval system that has better retrieval effectiveness than the traditional key-word systems. In this system, each document is assigned context(s) based on the type of information. This paper presents context categories for documents in computing and information technology domain and offers a new methodology for assigning context to documents in a collection. This methodology showed promising results and the inter-assigner consistency quite comparable to the results reported in literature. The comparative evaluation of context-based information retrieval system with a baseline information retrieval system showed promising results.
