“Entity Linking in Queries: Tasks and Evaluation,” an upcoming ICTIR 2015 paper by Faegheh Hasibi, Svein Erik Bratsberg, and myself is available online now. The resources developed within this study are also made publicly available.
Annotating queries with entities is one of the core problem areas in query understanding. While seeming similar, the task of entity linking in queries is different from entity linking in documents and requires a methodological departure due to the inherent ambiguity of queries. We differentiate between two specific tasks, semantic mapping and interpretation finding, discuss current evaluation methodology, and propose refinements. We examine publicly available datasets for these tasks and introduce a new manually curated dataset for interpretation finding. To further deepen the understanding of task differences, we present a set of approaches for effectively addressing these tasks and report on experimental results.
