SELECTION OF ASSOCIATED CONTENT FOR CONTENT ITEMS
First Claim
1. A method of selecting a content item, the method comprising:
- providing a plurality of associated term sets, each associated term set of the plurality of associated term sets comprising a set of terms characterizing a content item of a group of content items;
providing a set of semantic graphs, each semantic graph of the set of semantic graphs comprising nodes corresponding to terms and edges corresponding to a relationship between terms of nodes connected by the edge;
providing a search term set comprising terms characterizing a first content item;
expanding the search term set in response to a first semantic graph of the set of semantic graphs to generate an expanded set of terms;
determining similarity measures between the expanded set of terms and each of the plurality of associated term sets; and
selecting an associated content item for the first content item from the group of content items in response to the similarity measures.

Abstract
A content device may select associated content, such as adverts, for a user selected content item based on textual characterizing data for the associated content and the user selected content item. A term set characterizing the user selected content item is expanded using semantic graphs and similarity values between the expanded term set and term sets describing associated content is calculated. A specific associated content item is then selected based on the similarity values. The semantic graph based term set expansion may allow improved accuracy in selecting appropriate associated content while providing a process that is suitable for resource constrained scenarios. In particular, communication resource, memory resource, and computational resource usage may be kept low.
