| 20080313142 | CATEGORIZATION OF QUERIES - Determination of a target category associated with a business listings query is provided. A query categorization system initially generates a mapping of internal categories of the query categorization system to target categories of a search engine service. The query categorization system receives a business listings query and identifies business listings that match the query. The query categorization system identifies an internal category associated with each matching business listing. The query categorization system then identifies from the mapping the target categories that correspond to the identified internal categories. The query categorization system selects one of the identified target categories as the category to be associated with the query. | 12-18-2008 |
| 20080319974 | MINING GEOGRAPHIC KNOWLEDGE USING A LOCATION AWARE TOPIC MODEL - Mining geographic knowledge using a location aware topic model is provided. A location system estimates topics and locations associated with documents based on a location aware topic (“LAT”) model. The location system generates the model from a collection of documents that are labeled with their associated locations. The location system generates collection level parameters based on an LDA-style model. To generate the collection level parameters, the location system estimates probabilities of latent topics, locations, and words of the collection. After the model is generated, the location system uses the collection level parameters to estimate probabilities of topics and locations being associated with target documents. | 12-25-2008 |

| 20110295567 | MIXTURE MODELING WITH COMPONENT-DEPENDENT PARTITIONS - Described are variational Expectation Maximization (EM) embodiments for learning a mixture model using component-dependent data partitions, where the E-step is sub-linear in sample size while the algorithm still maintains provable convergence guarantees. Component-dependent data partitions into blocks of data items are constructed according to a hierarchical data structure comprised of nodes, where each node corresponds to one of the blocks and stores statistics computed from the data items in the corresponding block. A modified variational EM algorithm computes the mixture model from initial component-dependent data partitions and a variational R-step updates the partitions. This process is repeated until convergence. Component membership probabilities computed in the E-step are constrained such that all data items belonging to a particular block in a particular component-dependent partition behave in the same way. The E-step can therefore consider the blocks or chunks of data items via their representative statistics, rather than considering individual data items. | 12-01-2011 |
