Entity Search with NECESSITY

Loosely structured heterogeneous information spaces are typically created by merging data from a variety of dierent applications and information sources. A common problem these information spaces need to address is that various data describe the same real-word entities (e.g., people, conferences, organizations). In this demo, we introduce necessity, an ecient and scalable entity store. necessity is able to handle a large number of entities and at the same time provide an ecient and highly accurate entity search functionality for heterogeneous and partially structured queries that follow the vision of dataspaces.
