Semantic Web Lab
Department of Maths and Computer Science
University of Cagliari
The Semantic Web Lab is mainly devoted to the design, analysis and experimentation of algorithms and systems involving Big structured and unstructured Data for the Web, such as knowledge graphs, massive textual data, web and source code repositories.
Our effort is particularly focused on automating or simplifying access to these resources with innovative query systems, such as Question Answering over Linked Data, Machine Reading, SPARQL extensions and our By-Example Structured Query approach.

The Semantic Web Lab has a number of international ongoing collaborations, including those with the Web Information Systems Laboratory at the Scalable Analytics Institute (UCLA), and the STLab at ISTC (CNR).
In the following the list of some projects currently undertaken by our lab.
- OKgraph OKgraph: automatic learning and querying the Sardinian Open Knowledge Graph. Creating Knowledge Graphs from scratch, without human intervention. Founded by Regione Sardegna through Sardegna Ricerche.
- swipeQA Exploiting Structured Queries in Question Answering and Search. In collaboration with Prof. Carlo Zaniolo (UCLA), awarded by a Google Faculty Research Award.
- SWiPE Searching Wikipedia by Example, a user-friendly interface for structured queries
- Security Horizons A consortium of universities working on security and privacy issues (PRIN 2010-11 project)
- wfn Web of Functions, executable functions spread around the Web
- SPARQL4coding Massive dataset of Source code repositories that can be queried with SPARQL
