20140129566 | Method and Apparatus for Geographic Document Retrieval - A geographic document retrieval method (GDR) can be executed by a computer system to index, retrieve and rank geographical documents. Textual and spatial attributes of geographical documents are indexed separately using inverted index and spatial index, respectively. Spatial attributes of a document are represented as one or more contiguously closed regions of arbitrary shapes. Upon receiving an input query carrying a geographic representation of a location using arbitrary regions, the GDR method retrieves one or more documents by executing an overlap test between arbitrary regions from the query and the arbitrary regions associated with the documents. | 05-08-2014 |
20140129293 | Method and Apparatus for Dynamic Fencing - The present disclosure provides embodiments of an apparatus and method for generating dynamic fences representing geographical regions where advertisement campaigns can take place. The dynamic fences can have arbitrary shapes and can change over time and in real-time. The method comprises receiving campaign information via connections to a packet-based network; generating at least one dynamic fence of arbitrary shape based on the campaign information; and updating the at least one dynamic fence in response to data received from the packet-based network. | 05-08-2014 |
20140128104 | Method and Apparatus for Probabilistic User Location - A method of delivering location-based information comprises receiving a request including a location indicator from a packet-based network and translating the location indicator into a probabilistic representation of one or more possible locations of a mobile user based on historical data collected from mobile devices. By generating the probabilistic user location representation, the method can be used to deal with the inherent uncertainty in user location data, particularly in a mobile world,. In some embodiments, this is done by using validation, context analysis, creation of consistent groups, and probability allocation procedures. Location-based document retrieval can be enabled using the probabilistic user location representation. | 05-08-2014 |
