How Part-of-Speech Tags Affect Text Retrieval and Filtering Performance [article]

Robert M. Losee
1996 arXiv   pre-print
Natural language processing (NLP) applied to information retrieval (IR) and filtering problems may assign part-of-speech tags to terms and, more generally, modify queries and documents.  ...  In addition to a prediction of performance with tags, upper and lower bounds for retrieval performance are derived, giving the best and worst effects of including part-of-speech tags.  ...  An Analytic Model of Text Retrieval Retrieval and ltering systems may be evaluated using any of a number of measures, described in standard retrieval texts (Salton & McGill, 1983; Van Rijsbergen, 1979  ...

Validating a Model Predicting Retrieval Ordering Performance with Statistically Dependent Binary Features

Robert M. Losee
2015 International Journal of Information Retrieval Research  
These predictive methods may be used in a range of retrieval and media applications that examine the similarity between statements of needs such as "queries," and documents, media, genes, and realia.  ...  Information retrieval performance may be measured retrospectively, after experiments have been conducted or other data has been gathered, or performance may be predicted for systems before retrieval, given  ...  performance given query, relevance values, and databases.  ...
