DAKKAR:
A deeper look into the project


It's a Starting Grants project sponsored by University of Padua and Fondazione Cassa di Risparmio di Padova e di Rovigo.

The project aims to promote the development and evolution of user-oriented keyword based search systems for structured data by defining and implementing large, open, public and sustainable evaluation activities.

Keyword Search (KWS) Systems Code

We provide an open source JAVA implementation of the state of the art approaches for KWS over relational databases (BANKS, BANKS-2, DPBF) as Baseline Systems for the task.

We have choosen JGraphT library for implementing the graph data structure along with the graph-based search techniques. This is designed to scale to millions of vertices and edges.

In the current implementation we deal with PostgreSQL databases, but the code can be easily extended to handle other relational DBMS.
