A query comprising a set of keywords may be applied to a data set having various attributes, but it may be difficult to determine the query predicates intended for each keyword (e.g., the attributes targeted by each keyword, and the values of those attributes satisfying the keyword.) The meaning of a keyword of interest may be inferred from a set of query pairs, comprising a background query (comprising a set of keywords excluding the keyword of interest) and a foreground query (comprising the same set of keywords but also including the keyword of interest.) Differences in the query results for the foreground query and the background query of many query pairs may identify a query predicate intended by the keyword and a confidence score. These results may be associated with the keyword in a keyword map, useful for translating queries into query predicates that may yield relevant query results. |
