Two AKSW Papers at WWW

February 17, 2013 - 1:04 am by AxelNgonga - 2 comments »

The AKSW papers “Sorry, I don’t speak SPARQL – Translating SPARQL Queries into Natural Language” and “Question Answering on Interlinked Data” were accepted as full research papers for presentation at WWW2013. The first paper presents SPARQL2NL, a framework which  deals with the translation of SPARQL queries (and RDF triples) into natural language. The intention behind SPARQL2NL is to support for lay users who want to know what happens in the backend of the semantic system they are using. The framework has already been integrated into two pieces of software, i.e., the question answering engine TBSL and BioASQ‘s annotation tool for bio-medical questions. Moreover, it was shown to be of help for both SPARQL experts and non-experts. Check out the demo here. The second paper focuses on keyword search and question answering on interlinked data sets and shows how links across knowledge bases can be used to answer questions that require aggregating knowledge from several knowledge bases. The final versions of the papers will be made available soon. Please check them out and let us know what you think.

Looking forward to seeing you at WWW,
Axel for AKSW

Sorry, I don’t speak SPARQL – A Survey

May 25, 2012 - 10:54 am by Jens Lehmann - 7 comments »

Many Semantic Web applications are currently based on SPARQL. In particular, an increasing number of systems, such as question answering systems, keyword search or search by example internally construct SPARQL queries. However, lay users do not understand this language, so it is difficult to give the user feedback on what queries the system constructed. To address the gap between SPARQL and natural language, the AKSW and CITEC groups have devised an approach for transforming SPARQL queries to natural language.

You (yes, you!) can help us by judging the quality of the translations we present in this survey:

The survey can be done by both – SPARQL experts and lay users. For lay users, it takes 5 minutes to complete and 15 minutes for experts. In addition to the interesting (sometimes challenging) questions, there are also great prizes to win. 10 randomly selected participants will receive Amazon vouchers:

1st prize: 200 Euro
2nd prize: 100 Euro
3rd prize: 50 Euro
4th – 10th prize: 25 Euro

If you want to win a prize, you need to fill in your name at the end of the survey.

Enjoy the survey,
