Multiple entities of the same type have the same properties and share the same set of domain concepts.
we compute the semantic relatedness of a word w and an entity e based on the semantic similarity between w and the properties of e. semantic relatedness SR(e, w) is defined as "bed#n#1" "picture#n#2" "size#n#1" "color#n#1" "dresser#n#4"  where c i e is the i-th property of entity e, s(c i e ) is the synset of property c i e as designed in domain model, s j (w) is the j-th synset of word w as defined in wordNet, and sim(•, •) is the similarity score of two synsets.
