New Approaches to Spoken Document Retrieval

This paper presents four novel techniques for open-vocabulary spoken document retrieval: a method to detect slots that possibly contain a query feature; a method to estimate occurrence probabilities; a technique that we call collection-wide probability re-estimation and a weighting scheme which takes advantage of the fact that long query features are detected more reliably. These four techniques have been evaluated using the TREC-6 spoken document retrieval test collection to determine the improvements in retrieval effectiveness with respect to a baseline retrieval method. Results show that the retrieval effectiveness can be improved considerably despite the large number of speech recognition errors.

A Fusion Approach to XML Structured Document Retrieval

In this paper we evaluate the application of data fusion or meta-search methods, combining different algorithms and XML elements, to content-oriented retrieval of XML structured data. The primary approach is the combination of a probabilistic methods using Logistic regression and the Okapi BM-25 algorithm for estimation of document relevance or XML element relevance, in conjunction with Boolean approaches for some query elements. In the evaluation we use the INEX XML test collection to examine the relative performance of individual algorithms and elements and compare these to the performance of the data fusion approaches.

Online Retrieval of Environmental and Occupational Health Literature:

A formal study was attempted to assess the utility of the various online database sources for obtaining material in the fields of occupational and environmental health. Five databases were studied comparatively: BIOSIS, ENVIROLINE, EXCERPTA MEDICA, MEDLINE, and TOXLINE. In addition to crossdatabase searching to draw comparisons, a study of the journal coverage of four of these databases was completed. The goal of this effort was to establish some "databases of choice" for searching the literature.
