Abstract

One of the difficulties in using current Boolean-based information retrieval systems is that it is hard for a user, especially a novice, to formulate an effective Boolean query. Query reformulation can be even more difficult and complex than formulation since users often have difficulty incorporating the new information gained from the previous search into the next query. In this article, query reformulation is viewed as a classification problem, that is, classifying documents as either relevant or non relevant. A new reformulation algorithm is proposed which builds a tree-structure classifier, called a query tree, at each reformulation from a set of feedback documents retrieved from the previous search. The query tree can easily be transformed into a Boolean query. The query tree is compared to two query reformulation algorithms on benchmark test sets (CACM, CISI, and Medlars). In most experiments, the query tree showed significant improvements in precision over the 2 algorithms compared in this study. We attribute this improved performance to the ability of the query tree algorithm to select good search terms and to represent the relationships among search terms into a tree structure

Abstract

As more online databases are integrated into digital libraries, the issue of quality control of the data becomes increasingly important, especially as it relates to the effective retrieval of information. Authority work, the need to discover and reconcile variant forms of strings in bibliographical entries, will become more critical in the future. Spelling variants, misspellings, and transliteration differences will all increase the difficulty of retrieving information. We investigate a number of approximate string matching techniques that have traditionally been used to help with this problem. We then introduce the notion of approximate word matching and show how it can be used to improve detection and categorization of variant forms. We demonstrate the utility of these approaches using data from the Astrophysics Data System and show how we can reduce the human effort involved in the creation of authority files
