mining and similar areas. The main reason of using OLAP to answer queries is speed. Relational databases store entities in discrete tables if they have been properly normalized. This structure is good for operational databases but for complex multi-table queries is comparatively slow. A better model for querying but worse for operational use is the dimensional database. OLAP take a snapshot of a relational database and restructures it into dimensional data. The queries can ten be run against

Yet for many types of entities‚ such as restaurants and cult movies‚ relational databases exist that contain far more extensive information than Wikipedia. This paper introduces a new task‚ called Open-Database Named-Entity Disambiguation (Open-DB NED)‚ in which a system must be able to resolve named entities to symbols in
