Determining whether a textual phrase denotes a functional relation (i.e., a relation that maps each domain element to a unique range el- ement) is useful for numerous NLP tasks such as synonym resolution and contradic- tion detection. Previous work on this prob- lem has relied on either counting methods or lexico-syntactic patterns. However, determin- ing whether a relation is functional, by ana- lyzing mentions of the relation in a corpus, is challenging due to ambiguity, synonymy, anaphora, and other linguistic phenomena. We present the LEIBNIZ system that over- comes these challenges by exploiting the syn- ergy between the Web corpus and freely- available knowledge resources such as Free- base. It first computes multiple typed function- ality scores, representing functionality of the re...
