摘要:
A system and method for location-specific searching. The invention correctly identifies explicit and implicit locations in a search query, and provides an appropriate dominant location. Top search results are obtained and analyzed to determine which terms in the query often appear in combination, and the query is tokenized based on the analysis. An explicit location indicating a location intent is most likely treated as an individual token, and the explicit location is treated as the dominant location of the query. In the case of a false positive, wherein the explicit location in a query is not the location intent, the explicit location is likely to be present with other terms that provide context. A token will likely include these terms together. The explicit location will therefore not be used to generate location-specific results in the case of a false positive.
