Abstract
Concept-based ranking is applied to the results of a search process. Concept-based ranking relies on the input query, that produced the search results, having pinnacle concept properties specified for some of its keyword-based search terms. For each record “r” of a search result, it can be assigned a concept-based ranking score as follows. For each query term “QT,” of the input query, the following can be performed. The set of occurrences of “QT,” in the record, can be determined. Based upon the pinnacle concept of “QT,” and certain characteristics of the set of occurrences, a value can be assigned to “QT.” Characteristics, of the set of occurrences, can include the type of pinnacle concept asserted by at least one sub-unit of the record in which there is an occurrence. Once each “QT” has been assigned a value, such values can be combined to produce a score for ranking the record.
