Simple Weighting Techniques for Query Expansion in Biomedical Document Retrieval
In this paper, we propose two weighting techniques to improve performances of query expansion in biomedical document retrieval, especially when a short biomedical term in a query is expanded with its synonymous multi-word terms. When a query contains synonymous terms of different lengths, a traditional IR model highly ranks a document containing a longer terminology because a longer terminology...

متن کاملTerm Weighting in Short Documents for Document Categorization, Keyword Extraction and Query Expansion
This thesis focuses on term weighting in short documents. I propose weighting approaches for assessing the importance of terms for three tasks: (1) document categorization, which aims to classify documents such as tweets into categories, (2) keyword extraction, which aims to identify and extract the most important words of a document, and (3) keyword association modeling, which aims to identify...
متن کاملPhonetic query expansion for spoken document retrieval
We are interested in retrieving information from speech data using phonetic search. We show improvement by expanding the query phonetically using a joint maximum entropy N-gram model. The value of this approach is demonstrated on Broadcast News data from NIST 2006 Spoken Term Detection evaluation.
متن کاملQuery Expansion and Query Reduction in Document Retrieval
We investigate two seemingly incompatible approaches for improving document retrieval performance in the context of question answering: query expansion and query reduction. Queries are expanded by generating lexical paraphrases. Syntactic, semantic and corpus-based frequency information is used in this process. Queries are reduced by removing words that may detract from retrieval performance. F...
