Another look at automatic text-retrieval systems

Abstract: Evidence from available studies comparing manual and automatic text-retrieval systems does not support the conclusion that intellectual content analysis produces better results than comparable automatic systems.

Fast and intuitive clustering of web documents

Abstract: Conventional document retrieval systems (e.g., Alta Vista) return long lists of ranked documents in response to user queries. Recently, document clustering has been put forth as an alternative method of organizing retrieval results (Cutting et al. 1992). A person browsing the clusters can discover patterns that could be overlooked in the traditional presentation. This paper describes two novel clustering methods that intersect the documents in a cluster to determine the set of words (or phrases) shared by all the documents in the cluster. We report on experiments that evaluate these intersection-based clustering methods on collections of snippets returned from Web search engines. First, we show that word-intersection clustering produces superior clusters and does so faster than standard techniques. Second, we show that our O(n log n) time phrase-intersection clustering method produces comparable clusters and does so more than two orders of magnitude faster than all methods tested.

Natural language processing for online applications : text retrieval, extraction and categorization

Abstract: This text covers the emerging technologies of document retrieval, information extraction, and text categorization in a way which highlights commonalities in terms of both general principles and practical issues. It seeks to satisfy a need on the part of technology practitioners in the Internet space, faced with having to make difficult decisions as to what research has been done and what the best practices are. It is not intended as a vendor guide or as a recipe for building applications. But it does identify the key technologies, the issues involved, and the strengths and weaknesses of the various approaches. There is also a strong emphasis on evaluation in every chapter, both in terms of methodology (how to evaluate) and what controlled experimentation and industrial experience have to tell us.

Overview of the second text retrieval conference (TREC-2)

Abstract: The second Text Retrieval Conference (TREC-2) was held in August, 1993, and was attended by about 150 people involved in 31 participating groups. The goal of the conference was to bring research groups together to discuss their work on a new large test collection. There was a large variation of retrieval techniques reported on, including methods using automatic thesaurii, sophisticated term weighting, natural language techniques, relevance feedback, and advanced pattern matching. As results had been run through a common evaluation package, groups were able to compare the effectiveness of different techniques, and discuss how differences between the systems affected performance.

Method and apparatus for accessing and publishing electronic documents

Abstract: A document retrieval and accessing system in which documents are provided with links to other documents. Selection of one or more of the links causes the corresponding documents to be retrieved and sent to the requesting party. Then retrieved documents may also include links to yet even more documents.
