Keyword-based search

Last Updated on Wednesday, 18 February 2015 17:54

Typically, structured data sources are queried by means of structured languages, thus making possible to access data only for advanced users who are familiar with the syntax of the language and are able to formulate structured queries. Systems based on keywords do not require such knowledge, enabling the casual user to access the data. The idea in this project is to develop techniques for enabling keyword search on structured databases.
