Investigating Aboutness Axioms using Information Fieldsexperimentally. Such a comparison occurs as follows: Both retrieval mechanisms are first mapped to an associated information field. Within the field, the axioms that drive the retrieval process can be filtered out. Tn this way, the implicit assumptions governing an information retrieval mechanism ca

A Probabilistic Terminological Logic for Modelling Information Retrievalingly, the relevance of a given document to a given information need should be assessed by checking the validity of the logical formula . → .,where d is the representation of the document, n is the representation of the information need and “→” is the conditional connective of the logic in question.

Retrieving Terms and their Variants in a Lexicalized Unification-Based Frameworkatch with their initial string or inflection. We show that a local syntactic approach to this problem can give good results for both the quality of identification and parsing time..A specific tool, ., is developed which handles an identification of basic terms and a parser of their variations as wel

A Sequential Algorithm for Training Text Classifiers developed and tested on a newswire text categorization task. This method, which we call uncertainty sampling, reduced by as much as 500-fold the amount of training data that would have to be manually classified to achieve a given level of effectiveness.

An Evaluation Method for Stemming Algorithmsinst predefined concept groups in samples of words. This enables various indices of stemming performance and weight to be computed. Results are reported for three stemming algorithms. The validity and usefulness of the approach, and the problems of conceptual grouping, are discussed, and directions for further research are identified.

Term Relevance Feedback and Query Expansion: Relation to Designces were the users written question statement, user terms derived during the interaction and terms selected from particular database fields. These findings indicate the need for the design and testing of automatic relevance feedback techniques that place greater emphasis on these sources.

Modelling Information Retrieval Agents with Belief Revisionrch shows that such approaches can be implemented in an essentially principled manner, though there are many large problems still to be overcome, and our experiments are only the first, extremely simple, trials of the basic strategy for intermediary simulation.

Using IR Techniques for Text Classification in Document Analysisoutput, the system evaluates a set of weighted hypotheses about the type of the actual letter. Classification of documents allow the automatic distribution or archiving of letters and is also an excellent starting point for higher-level document analysis..
