Shaul Dar, Gadi Entin, Shai Geva, Eran Palmon · 1998
DTL’s DataSpot is a database publishing tool that enables non-technical end users to explore a database using free-form plain language queries combined with hypertext navigation. DataSpot is based on a novel representation of data in the form of a schema-less semi-structured graph called a hyperbase. The DataSpot Publisher takes one or more possibly heterogeneous databases, predefined knowledge banks such as a thesaurus, and user-defined associations, and creates the hyperbase.

The DataSpot product has been successfilly deployed in diverse application areas including electronic catalogs, yellow pages, classified ads, help desks and finance.
