AGGREGO SEARCH: Interactive Keyword Query Construction

AGGREGO SEARCH offers a novel keyword-based query solution for end users in order to retrieve precise answers from semantic data sources. Contrary to existing approaches, AGGREGO SEARCH suggests grammatical connectors from natural languages during the query formulation step in order to specify the meaning of each keyword, thus leading to a complete and explicit definition of the intent of the search. An example of such a query is name of person at the head of company and author of article about “business intelligence". In order to help users formulate such connected keywords queries, a specific autocompletion strategy has been developed. A translation of the user keyword query into SPARQL is performed on-the-fly during the interactive query construction process. For this demonstration, we show how AGGREGO SEARCH has been integrated on top of a mediation system to let users intuitively define explicit and precise keyword queries in order to extract knowledge distributed in heterogeneous large semantic data sources.
