Abstract:
In this paper, we present a web application for entity ranking. The application accepts as input a query in natural language and outputs a list of the most relevant entities according to the query. The system uses web documents as data and performs extraction, formatting and ranking of entities in real time. An experiment is conducted to determine the most efficient ranking method among six alternatives. The experiment suggests that the total frequency of an entity in a retrieved set of documents has less to say on the entity's relevance than the number of retrieved documents it occurs in. Furthermore, for small retrieved sets such as the top-10, document rank information seems to play a little role.
