  • Publication number: 20120117050
    Abstract: Techniques are provided for creating and updating a entity hierarchy (taxonomy) based on information captured about user interaction with a system. Techniques are also provided for using the taxonomy to determine the nature of entities represented by terms submitted to a search engine. Search logs analyzed for related sets of entities, and used to improve the taxonomy for storing information. Once the taxonomy is created, information across data sources are fetched and aggregated based on the taxonomy. When the system is queried, the query is modified to a predefined template, and the best fit result is promptly returned. A feedback mechanism is also provided to enhance taxonomy and entity data based on search volumes. This system enables search engines to provide accurate answers when entities, their attributes and relationships are involved.

  • Publication number: 20100205131
    Abstract: Particular embodiments of the present invention are directed to systems and methods for predicting the outcome of events based on internet activity associated with such events. For example, an internet activity metric associated with one or more events may be determined. The internet activity metric may be based at least on the popularity of particular search terms related to the events. The outcomes of the events may also be determined. The determined internet activity metrics and the outcomes of the one or more events may be analyzed to generate an algorithm for predicting the outcomes of subsequent events. For example, an internet activity metric associated with a particular subsequent event (e.g., based at least on the popularity of a particular search term related to the subsequent event) may be determined, and the algorithm may be applied to the internet activity metric to predict the outcome of the particular subsequent event.

  • Publication number: 20100145941
    Abstract: An application conforming to a set of rules is described for improving the accuracy of results provided by image search engines through identifying images as true positive hits, true negatives, false positive hits, and false negatives. The set of rules comprise: (1) causing players to associate given images with given metadata; (2) associating a player with a skill level; (3) utilizing measures of accuracy and time; (4) causing players to select a few images from a relatively large pool of images; and (5) testing player tolerance. An application that conforms to these rules test the relevancy of images to given metadata tags. The application provides information that is the basis for adjusting the metadata associated with the tested images so as to improve the relevancy of image search results lists that include these images.
