Query Substitution based on N-gram Analysis
نویسندگان
چکیده
Query substitution replaces original query words with a new words that express the same meaning. In this paper, the technique of n-gram analysis is proposed to find the synonyms or quasi-synonyms of the original query word. The synonyms found are then incorporated into the original query with different methods. Experiments show that the proposed n-gram analysis techniques can obtain interesting synonyms, which help to improve retrieval effectiveness.

متن کاملAnnotation and verification of sense pools in OntoNotes
The paper describes the OntoNotes, a multilingual (English, Chinese and Arabic) corpus with large-scale semantic annotations, including predicate-argument structure, word senses, ontology linking, and coreference. The underlying semantic model of OntoNotes involves word senses that are grouped into so-called sense pools, i.e., sets of near-synonymous senses of words. Such information is useful ...
متن کاملAn Efficient Indexer for Large N-Gram Corpora
We introduce a new publicly available tool that implements efficient indexing and retrieval of large N-gram datasets, such as the Web1T 5-gram corpus. Our tool indexes the entire Web1T dataset with an index size of only 100 MB and performs a retrieval of any N-gram with a single disk access. With an increased index size of 420 MB and duplicate data, it also allows users to issue wild card queri...
