document: EntityTagger : automatically tagging entities with descriptive phrases We consider the problem of entity tagging : given one or more named entities from a specific domain , the goal is to automatically associate descriptive phrases , referred to as etags ( entity tags ) , to each entity . Consider a product catalog containing product names and possibly short descriptions . For a product in the catalog , say Ricoh G600 Digital Camera , we want to associate etags such as `` water resistant '' , `` rugged '' and `` outdoor '' to it , even though its name or description does not mention those phrases . Entity tagging can enable more effective search over entities . We propose to leverage signals in web documents to perform such tagging . We develop techniques to perform such tagging in a domain independent manner while ensuring high precision and high recall .
