Iterative Set Expansion of Named Entities Using the Web

Iterative Set Expansion of Named Entities Using the Web
Set expansion refers to expanding a partial set of “seed” objects into a more complete set. One system that does set expansion is SEAL (Set Expander for Any Language), which expands entities automatically by utilizing resources from the Web in a language independent fashion. In a previous study, SEAL showed good set expansion performance using three seed entities; however, when given a larger set of seeds (e.g., ten), SEAL’s expansion method performs poorly. In this paper, we present Iterative SEAL (iSEAL), which allows a user to provide many seeds. Briefly, iSEAL makes several calls to SEAL, each call using a small number of seeds. We also show that iSEAL can be used in a “bootstrapping” manner, where each call to SEAL uses a mixture of user-provided and self-generated seeds. We show that the bootstrapping version of iSEAL obtains better results than SEAL using fewer user-provided seeds. In addition, we compare the performance of various ranking algorithms used in iSEAL, a...
