Abstract:
Methods and computer-readable media are provided for ranking search results using feature extraction data. Each of the results of a search engine query is parsed to obtain data, such as text, formatting information, metadata, and the like. The text, the formatting information and the metadata are passed through a feature extraction application to extract data that may be used to improve a ranking of the search results based on relevance of the search results to the search engine query. The feature extraction application extracts features, such as titles, found in any of the text based on formatting information applied to or associated with the text. The extracted titles, the text, the formatting information and the metadata for any given search results item are processed according to a field weighting application for determining a ranking of the given search results item. Ranked search results items may then be displayed according to ranking.
