Hinweis der Redaktion
- The work I will present today is a collaboration between the Ontology Engineering Group at Universidad Politécnica de Madrid and Universität Bielefeld
- But is also the result of many discussions among the partners of the EU project LiderBut, what is Lider?Lider is a support and coordination action with the goal of setting the pathway for the creation of an ecosystem linguistic Linked Data and NLP services to support enterprise content analytics in Europe. And a crucial issue to achieve this is to listen to industry and the community, so please join us in the newly created W3C Linked Data for Language technologies CG.In this discussions with the community there are several recurring topics such as data modelling, quality, provenance, etc. But one of them seems to be of special relevancy and that will be the main topic of this talk.The main outcome of the project will be a roadmap for EU, several guidelines to help data publishers and consumers, a reference architecture and an industrial community
- As you might have guessed from the tile, the topic is Licensing Linked Data and in particular Linguistic Linked Data, but why is this important?No matter you are publishing Open Data or data under more restrictive terms, you and the potential data consumers will benefit from providing a license along with your data.In the case of Open Data …For data under more restrictive terms of use…Given that everyone seems to agree on this, what is actually the current practice?In 2013, member of my group performed a study on the so-called Linked Data cloud and the results were a bit surprising, (or maybe not).
- Although there's a lot of green areas (with licenses such as public domain, those that require attribution), you can see several red and orange areas corresponding to restrictive licenses and a considerable mass of grey which corresponds to
- If you are interested u can read the paper, but as u can see in this graph almost 50% of the datasets are published either under not specified licenses or even closed licenses.
- Going back to our topic, linguistic linked data. As you might be aware recently a new cloud of LLD has emerged with the support of the Open Data and Linguistics working group. One can look at this cloud from several perspectives language, type of resource, data models or quality, but what about the licenses, how open is this cloud?
- In this case we found out that it is certainly more open than the LOD cloud, although there's still around 13 percent of unspecified or restrictive licenses. Adittionaly, this cloud has been selected and curated by a working group, but what willl happen when the scope gets broader including resources from ELRA or metashare for example?
- This concern is why we have came up with the concept of 3LD which stands for Linguistic Linked Licensed Data
