The experimental evidence accumulated over the past 20 years indicates that text indexing systems based on the assignment of appropriately weighted single terms produce retrieval results that are superior to those obtainable with other more elaborate text representations. These results depend crucially on the choice of effective termweighting systems. This… (More)
In a document retrieval, or other pattern matching environment where stored entities (documents) are compared with each other or with incoming patterns (search requests), it appears that the best indexing (property) space is one where each entity lies as far away from the others as possible; in these circumstances the value of an indexing system may be… (More)
Relevance feedback is an automatic process, introduced over 20 years ago, designed to produce improved query formulations following an initial retrieval operation. The principal relevance feedback methods described over the years are examined briefly, and evaluation data are included to demonstrate the effectiveness of the various methods. Prescriptions are… (More)
Gerard Salton has worked on a number of non-numeric computer applications including automatic information retrieval. He has published a large number of articles and several books on information retrieval, most recently, "Introduction to Modern Information Retrieval," 1983. Edward Fox is currently assistant professor of computer science at VPI. Harry Wu is… (More)
Advances such as specialized parallel hardware and new algorithms for text searching will improve the effectiveness of information retrieval systems.
The Smart information retrieval project emphasizes completely automatic approaches to the understanding and retrieval of large quantities of text. We continue our work in TREC 3, performing runs in the routing, ad-hoc, and foreign language environments. Our major focus is massive query expansion: adding from 300 to 530 terms to each query. These terms come… (More)
Automatic indexing methods are evaluated and design criteria for modern information systems are derived.
-In recent years, information retrieval techniques have been used for automatic generation of semantic hypertext links. This study applies the ideas from the automatic link generation research to attack another important problem in text processing---automatic text summarization. An automatic "general purpose" text summarization tool would be of immense… (More)
