Web query classification
First Claim
1. A computer-implemented method for enabling satisfaction of a search responsive to a query based on classification of the query, the method comprising:
- receiving, based on user input, a query phrase;
parsing, with a processor, the received query phrase into at least a first constituent part and a second constituent part;
determining, with a processor, a first category associated with the received query phrase by performing a first classification process that uses the first constituent part and the second constituent part, wherein the first classification process includes;
accessing, from classification information stored in a storage medium that includes patterns, a pattern that is associated with at least one category, the pattern including a first part and a second part;
comparing the determined definitional information of the first constituent part with the first part included in the accessed pattern and comparing the second constituent part with the second part included in the accessed pattern;
based on the comparison results, determining whether the second constituent part and the determined definitional information of the first constituent part correspond to at least a subportion of the accessed pattern; and
based on a determination that the second constituent part and the determined definitional information of the first constituent part correspond to at least a subportion of the accessed pattern, identifying the at least one category that is associated with the pattern as the first category associated with the received query phrase;
determining a second category associated with the received query phrase by performing a second classification process that uses the first constituent part and the second constituent part, the second classification process being different than the first classification process;
determining whether the first category determined by the first classification process matches the second category determined by the second classification process;
in response to a determination that the first category matches the second category, associating the received query phrase with a category that corresponds to the first category and the second category;
in response to a determination that the first category does not match the second category;
selecting, from among the first category and the second category, a single category; and
associating the received query phrase with the single category selected; and
processing the received query phrase based on the associated category.

Abstract
A query phrase may be automatically classified to one or more topics of interest (e.g., categories) to assist in routing the query phrase to one or more appropriate backend databases. A selectional preference query classification technique may be used to classify the query phrase based on a comparison between the query phrase and patterns of query phrases. Additionally, or alternatively, a combination of query classification techniques may be used to classify the query phrase. Topical classification of a query phrase also may be used to assist a search system in delivering auxiliary information to a user who entered the query phrase. Advertisements, for instance, may be tailored based on classification rather than query keywords.

9. An apparatus for enabling satisfaction of a search responsive to a query based on classification of the query, the apparatus comprising:
-
at least one processor; at least one storage medium having instructions stored thereon which, when executed by the at least one processor, causes the at least one processor to; parse a received query phrase into at least a first constituent part and a second constituent part; determine a first category associated with the received query phrase by performing a first classification process that uses the first constituent part and the second constituent part, the first classification process including; accessing, from classification information stored in a computer storage medium that includes patterns, a pattern that is associated with at least one category, the pattern including a first part and a second part; comparing determined definitional information of the first constituent part with the first part included in the accessed pattern and comparing the second constituent part with the second part included in the accessed pattern; based on the comparison results, determining whether the second constituent part and the determined definitional information of the first constituent part correspond to at least a subportion of the accessed pattern; and based on a determination that the second constituent part and the determined definitional information of the first constituent part correspond to at least a subportion of the accessed pattern, identifying the category that is associated with the pattern as the first category associated with the received query phrase; determining a second category associated with the received query phrase by performing a second classification process that uses the first constituent part and the second constituent part, the second classification process being different than the first classification process; determining whether the first category determined by the first classification process matches the second category determined by the second classification process; in response to a determination that the first category matches the second category, associating the received query phrase with a category that corresponds to the first category and the second category; in response to a determination that the first category does not match the second category; selecting, from among the first category and the second category, a single category; and associating the received query phrase with the single category selected; and processing the received query phrase based on the associated category. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
