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.
We propose the design of a novel unified framework that supports the reproducibility and new implementation of graph-based Keyword Search Systems over relational data. The design of the framework is based on the pioneering systems BANKS, BANKS-II and DPBF. Along with the framework, we provide an open source JAVA implementation of a core module.
We have choosen JGraphT library for implementing the graph data structure. 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.
DAKKAR project is conducted by: Maristella Agosti, Vittoria Cozza, Nicola Ferro and Gianmaria Silvello Information Management Systems Research Group, Department of Information Engineering, University of Padua.
DAKKAR project is mainly conducted at University of Padua, and in collaboration with Department of Engineering "Enzo Ferrari", University of Modena and Reggio Emilia; Department of Computer, Control, and Management Engineering "Antonio Ruberti", Sapienza University of Rome.
