1. A method of processing a current user query, comprising:
- maintaining, by a computer system, a model comprising a plurality of entries, each entry of the model comprising a plurality of query features, a query intent, and an indication of a statistical association between the query feature and the query intent, wherein the plurality of query features comprise a query token, a stem for the query token, and a concept represented by the query token;
receiving, at the computer system, an initial portion of the current user query, the initial portion including a particular string of text;
guessing, by the computer system, an intent associated with the initial portion of the current user query while a remainder of the current user query is being received, wherein said guessing is based at least in part on the received initial portion, the query features of the entries of the model, and the indications of statistical association between the query features and the query intents of the model and comprises;
analyzing the initial portion to obtain at least one feature,comparing the obtained at least one feature of the initial portion to the query features of the entries in the model,selecting a plurality of entries from the model based on the comparison,determining the intent for the initial portion of the current user query according to the query intent in the selected plurality of entries and the statistical association between the query feature and the query intent, andgenerating a plurality of intent guesses that are different from the current user query and that do not include the particular text string based on the determined intent for the initial portion of the current user query wherein generating the intent guesses comprises identifying from the entries selected from the model a parameterized intent guess that includes at least one concept, identifying words that are associated with the concept but that are not the particular text string, and modifying the parameterized intent guess by replacing the concept with the identified words; and
responding, by the computer system, to the initial portion of the current user query with the plurality of intent guesses including the modified parameterized intent guess.

Abstract
An intent guessing system receives partial user queries as they are entered by the user. The partial user queries are compared with different intents derived from previously logged queries. Guesses are made as to which of the intents are associated with the partial user query. The intent guesses are then provided as responses to the user query. Features are identified for the earlier logged queries and associated with the derived intents. The derived intents and associated features are then used to identify intents for the partial user queries.

9. A method of processing a current user query, comprising:
-
training a model, said training comprising; logging previous user queries; extracting a query from the logged previous user queries; analyzing the extracted query to obtain a plurality of features, wherein the plurality of features comprise a query token, a stem for the query token, and a concept represented by the query token; assigning an intent to the extracted query; and adding an entry to the model and mapping the obtained features for the extracted query to the assigned intent for the extracted query in the added entry of the model; receiving an initial portion of the current user query, wherein the initial portion includes a particular string of text; guessing an intent associated with the initial portion of the current user query while a remainder of the current user query is being received, wherein said guessing is based at least in part on the received initial portion, the query features of the entries of the model, and the indications of statistical association between the query features and the query intents of the model and further comprises; analyzing the initial portion to obtain at least one feature, comparing, using a processing device, the obtained at least one feature of the initial portion to entries in the model, selecting, using the processing device, at least one entry from the model based on the comparison determining the intent for the initial portion of the current user query according to an intent included in the selected entry, and generating the intent guess based on the determined intent for the initial portion of the current user query wherein the intent guess is different from the current user query and that does not include the particular text string and wherein generating the intent guesses comprises identifying from the entries selected from the model a parameterized intent guess that includes at least one concept, identifying words that are associated with the concept but that are not the particular text string, and modifying the parameterized intent guess by replacing the concept with the identified words; and responding to the initial portion of the current user query with the intent guess including the modified parameterized intent guess. - View Dependent Claims (10, 11)
