document: Domain-independent entity extraction from web search query logs Query logs of a Web search engine have been increasingly used as a vital source for data mining . This paper presents a study on large-scale domain-independent entity extraction from search query logs . We present a completely unsupervised method to extract entities by applying pattern-based heuristics and statistical measures . We compare against existing techniques that use Web documents as well as search logs , and show that we improve over the state of the art . We also provide an in-depth qualitative analysis outlining differences and commonalities between these methods .
