**5. Experimental results and contributions**

We have designed and implemented two reference libraries. The first library is a Python library that has functions to extract/transform Webpages and create TULIP datasets. The second library is a JavaScript library to query TULIP endpoint, consume its result sets, and manipulate them. The code is provided in the GitHub repositories at https://github.com/julthep/tulip and https://github.com/julthep/ tulip.js respectively.

Furthermore, we experimented with TULIP vocabulary using Wikipedia as the data source by converting a number of articles into TULIP data format. The result datasets can be accessed via SPARQL endpoint at http://tlpedia.org/sparql/ or downloaded at http://tlpedia.org/datasets/. These datasets will be updated periodically, and the number of imported articles will be increased on a regular basis.
