Abstract
Cross-lingual query suggestions (CLQS) aims to suggest relevant queries in a target language for a given query in a source language. The cross-lingual query suggestion is improved by exploiting the query logs in the target language. The disclosed techniques include a method for learning and determining a similarity measure between two queries in different languages. The similarity measure is based on both translation information and monolingual similarity information, and in one embodiment uses both the query log itself and click-through information associated therewith. Monolingual and cross-lingual information such as word translation relations and word co-occurrence statistics may be used to estimate the cross-lingual query similarity with a discriminative model.
Claims20
A method for query suggestion, the method comprising:
- for an input query in source language, identifying a query in target language from a query log of a search engine, the query in target language and the input query in source language having a cross-lingual similarity satisfying a certain standard;
- and
- suggesting the query in target language as a cross-lingual query.
A method for query suggestion, the method comprising:
- receiving an input query in source language;
- providing a plurality of candidate queries in target language, at least part of the plurality of candidate queries in target language being selected from a query log of a search engine;
- ranking the plurality of candidate queries in target language using a cross-lingual query similarity score;
- and
- from top ranking candidate queries in target language, suggesting a query in target language as a cross-lingual query.
One or more computer readable media having stored thereupon a plurality of instructions that, when executed by a processor, causes the processor to:
- for an input query in source language, identify a query in target language from a query log of a search engine, the query in target language and the input query in source language having a cross-lingual similarity satisfying a certain standard;
- and
- suggest the query in target language as a cross-lingual query.
