A system and method for collecting entity aliases include a web object collection component that obtains, from a web search engine, at least one Web object associated with a user' input entity. The system and method also include a social tag collection component that obtains a respective set of social tags for each of the Web objects from a social tag website and defines candidate aliases for the user's input entity based upon the respective set of social tags. An aliases refinement component refines the candidate aliases to obtain a collection of aliases of the user's input entity.
