Abstract: An illustrative geolocation authentication system designates a movement feasibility corroboration factor as a location corroboration factor for the geolocation authentication system to authenticate geolocations of mobile devices. Based on the designating of the movement feasibility corroboration factor, the geolocation authentication system determines a first reported geolocation of a mobile device associated with a first time and a second reported geolocation of the mobile device associated with a second time. Given that the mobile device is located at a true geolocation at the second time, the geolocation authentication system then determines, based on the first and second reported geolocations of the mobile device, a feasibility metric indicative of a likelihood that the second reported geolocation of the mobile device is the true geolocation at the second time. Corresponding methods and systems are also disclosed.

Abstract: An exemplary virtual boundary system determines a refined geolocation of a tracking device based on a positioning signal and a correction signal that are accessed from distinct signal sources. The virtual boundary system compares the refined geolocation of the tracking device and a geographic boundary. Then, based on the comparing of the refined geolocation and the geographic boundary, the virtual boundary system provides an alert indicative of the refined geolocation with respect to the geographic boundary. Corresponding methods and systems are also disclosed.

Abstract: A system and method for a high-performance, scalable, multi-tenant, dynamically specifiable, knowledge graph information storage and utilization. The system uses an in-memory associative array for high-performance graph storage and access, with a non-volatile distributed database for scalable backup storage, a scalable, distributed graph service for graph creation, an indexing search engine to increase searching performance, and a graph crawler for graph traversal. One or more of these components may be in the form of a cloud-based service, and in some embodiments the cloud-based services may be containerized to allow for multi-tenant co-existence with no possibility of data leakage or cross-over.

Abstract: An exemplary geolocation authentication system receives user input representative of customized authentication settings that designate a location corroboration factor from a plurality of location corroboration factors that correspond to independent ways of determining geolocations of mobile devices. The system receives, from a mobile device located at a true geolocation, a reported geolocation of the mobile device. Then, in response to the receiving of the reported geolocation, the system accesses a datapoint that characterizes a correlation between the reported geolocation of the mobile device and the true geolocation of the mobile device. The datapoint characterizes the correlation based on the location corroboration factor designated by the customized authentication settings. The system further determines, based on the datapoint, a custom confidence metric representative of a likelihood that the reported geolocation is the true geolocation. Corresponding methods and systems are also disclosed.

Abstract: An exemplary virtual boundary system accesses a positioning signal generated by a positioning system. A geolocation for a real-time tracking device is derivable from the positioning signal within a first margin of error. The virtual boundary system also accesses a correction signal generated by a positioning enhancement system and corresponding to the positioning signal generated by the positioning system. Based on the positioning signal and the correction signal, the virtual boundary system determines a refined geolocation of the real-time tracking device relative to a user-specified geographic boundary. The refined geolocation is accurate within a second margin of error that is less than the first margin of error. Corresponding methods and systems are also disclosed.

Abstract: An exemplary dynamic virtual boundary system accesses a positioning signal, a corresponding correction signal, and data defining a user-specified geographic boundary configured to change in real time. The positioning signal is generated by a satellite within a satellite-based positioning system and is received by a real-time tracking device carried by a subject. The correction signal is generated by a terrestrial positioning enhancement system and is also received by the device. Based on the positioning and correction signals, the dynamic virtual boundary system continuously determines a refined geolocation of the device and continuously monitors whether the refined geolocation is within a predetermined distance of the boundary as the boundary changes in real time.

Abstract: Computer-implemented systems and methods are provided for parsing search queries. In accordance with some embodiments, search records including character strings are retrieved, and search query templates are generated comprising sequences of categories corresponding to character substrings of the character strings. Also, in accordance with some embodiments, search queries are parsed into character substrings and matched with a search query template. The search query template may then be used to associate categories with the character substrings. A search engine may use the categories to focus or otherwise refine a search based on parsed search query.

Abstract: Systems and methods are provided for providing an ordered list of search results in response to a query. Consistent with certain embodiments, computer-implemented systems and methods may identify content items corresponding to a query. First relevance scores may be determined for the identified content items based on their relevance to the query. Second relevance scores may be determined by modifying at least one of the first relevance scores using a boost value. The boost value may be set to a default boost value when the query does not include an override boost value. The boost value may be set to the override boost value, when the query includes an override boost value. An ordered list of the identified content items may be generated based on the second relevance scores. The ordered list may be displayed on a display device.

Abstract: Computerized systems and methods are provided for analyzing failed and successful search queries. In accordance with some embodiments, search records with character strings that are refinements of character strings of other search records are deemed related as belonging to a same user search. Minimum changed sections between character strings in related search records are determined. Correction pairs are created including the character sequences from the portions of the character strings containing the minimum changed sections. Frequencies of correction pairs in a pool of correction pairs are calculated, and the correction pairs appearing in the pool most frequently are stored in a correction log.
