QUERY CLASSIFICATION
First Claim
1. A method for providing query results based on categorization of searched content, comprising:
- generating classification metadata that identify a category to which a document in an index of documents is classified, where documents in the index have been classified into one or more category predictions for a category hierarchy; and
associating the classification metadata to the document in the index.

Abstract
Techniques and systems are disclosed that provide for constructing a query classification index that can be used to classify a query into relevant categories. Where documents in an index are classified into one or more category predictions for a category hierarchy, classification metadata is generated for categories to which a document in the index has been classified. Further, the classification metadata is associated to the corresponding documents in the index. Additionally, a query of the index can be classified using the metadata associated to the documents in the index, and query results can be provided that are classified by the one or more categories identified by the classification of the query.

16. A system for providing query results based on categorization of searched content, comprising:
-
computer-based storage configured to store classification metadata associated with documents in an index of documents; a metadata generator configured to generate classification metadata that identify a category to which a document in the index has been classified, where documents in the index have been classified into one or more category predictions for a category hierarchy; and a metadata association component, operably coupled to the storage, and configured to associate the classification metadata to the corresponding document in the index. - View Dependent Claims (17, 18, 19)

20. A method for providing query results based on categorization of searched content, comprising:
-
classifying document in an index into topic category prediction for a category hierarchy, comprising using a trained classifier to identify one or more categories for the document, based on a desired threshold; generating classification metadata, at crawl time of a source of documents for the index, that identify a topic category to which a document has been classified; associating the classification metadata to the document in the index at crawl time of a source of documents for the index; classifying a query of the index using the metadata associated to the documents in the index, comprising; identifying document results for the query from the index; and identifying one or more categories for respective documents from the results using a distribution of the categories for the results provided by the metadata; and providing one or more categories for the query based on a distribution of the one or more identified categories for respective documents in the results and providing query results classified by one or more categories using the classification of the query.
