ADAPTATION OF LOCATION SIMILARITY THRESHOLD IN ASSOCIATIVE CONTENT RETRIEVAL

摘要

Retrieval of similar content item or documents is provided based on similarity of their location or place. A base location is determined, for example using a GPS device. Location of one or more identified anchor document(s), in a database for example, is determined by extracting location data. Then a first threshold is set based on a criterion distance determined between the base location and the anchor item location. A candidate document item location is identified and the location data for candidate content item may be extracted. A distance between the base location and the candidate location may be determined as a candidate distance. A candidate content item may be selected as similar for retrieval based on the first candidate distance and the first threshold. The notion of criterion distance- determined granularity for setting a threshold is provided.
