Abstract: A method of matching a first entity to a second entity by evaluating Boolean expressions includes identifying a set of criteria vertices for a second entity vertex by traversing a graph database in a manner constrained to fact vertices identified for the second entity. The graph database relates fact vertices to the criteria vertices by edges corresponding to Boolean expressions for satisfying criteria for matching first entities to second entities. The method additionally includes selecting one of the first entities based on the criteria vertices of the set. The method further includes matching the first entity to the second entity based on the selection.

Abstract: A method for determining a score for a research survey to be deployed in a mobile environment is disclosed. The method includes receiving survey data descriptive of a survey to be distributed to a plurality of respondents, and analyzing the survey data to identify one or more attributes of the survey. The method includes generating a survey score for the survey based on the one or more attributes of the survey. The survey score is representative of a suitability of the survey for presentation at a mobile device. The method may include determining distribution information for the survey based at least in part on the survey score. The distribution information identifies a set of respondents of the plurality of respondents to receive the survey.

Abstract: Systems and methods are disclosed for conducting surveys of panelists via mobile devices without requiring persistent network connectivity with the mobile devices. A survey application is downloaded to a user's processor-based device, and executes locally on the device. A survey definition file is generated that specifies various information defining a given survey, such as specific questions to be asked, etc. The survey definition file is downloaded to the user's device. Once downloaded to the user's processor-based device, the survey definition file is interpreted by the survey application executing on the user's processor-based device in order to present a user interface on the user's processor-based device with which a user can interact to take the survey, as defined by the downloaded survey definition file. The survey definition file may be generated by a tool as a result of processing a predefined survey definition file.
