Description

Tasks relying on recognizing entities have recently received significant attention in the literature. Many such tasks assume the existence of reference entity tables. In this paper, we consider the problem of determining whether a candidate string approximately matches with a reference entity. This problem is important for extracting named entities such as products or locations from a reference entity table, or matching entity entries across heterogenous sources. Prior approaches have relied on string-based similarity which only compare a candidate string and an entity it matches with. In this paper, we observe that considering such evidence across multiple documents significantly improves the accuracy of matching. We develop efficient techniques which exploit web search engines to facilitate approximate matching in the context of our proposed similarity functions. In an extensive experimental evaluation, we demonstrate the accuracy and efficiency of our techniques.
