An information email in early September from Simon Hodson, the CODATA Executive Director, attracted my deep interest. His email was about the high-level political launch for the Global Partnership for Sustainable Development Data. I was interested because I have worked on Open Data in the past few years and the experience shows that Open Data much more comprehensive than a sole technical issue. I was excited to see that there will be such an event initiated by political partners and focusing on social impacts. And thanks to the support from the CODATA Early Career Data Professionals Working Group , which ...

Summary A relatively quiet quarter in world of (read-write) web standards. Generally my impression is that the emphasis is shifting more towards implementation, with most of the hard parts of design out, now of the way. Andrei gave a great presentation at the re-decentralize web conference in Brazil. There was quite a bit of discussion regarding decentralized identity, same origin policy and public / private key provisioning in the browser. In particular, the KEYGEN element was looked at, with some wanting to deprecate it. However, it was established that it's still in use and would not be deprecated just yet, ...

You have always thought that SPARQL is only a query language for RDF data? Then think again, because SPARQL can also be used to implement some cool analytics. I show here two queries that demonstrate that principle. For simplicity we use a publicly available dataset of DBpedia on an open SPARQL endpoint: http://live.dbpedia.org/sparql (execute with default graph = http://dbpedia.org ). Mean life expectancy for different sports The query shown here starts from the class dbp:Athlete and retrieves sub classes thereof that cover different sports. With that athletes of that areas are obtained and their birth and death dates (i.e. we ...

Tweet Clare Grasso, Anupam Joshi and ELior Siegel, Beyond NER: Towards Semantics in Clinical Text , Biomedical Data Mining, Modeling, and Semantic Integration (BDM2I); co-located with the 14th International Semantic Web Conference (ISWC 2015), Bethlehem, PA. While clinical text NLP systems have become very effective in recognizing named entities in clinical text and mapping them to standardized terminologies in the normalization process, there remains a gap in the ability of extractors to combine entities together into a complete semantic representation of medical concepts that contain multiple attributes each of which has its own set of allowed named entities or values. ...

Konrad Höffner will present the current state of the survey "Overcoming Challenges of Question Answering in the Semantic Web" , which will be submitted to the Semantic Web Journal. It is a joined work with the QA experts in the group and a researcher from Uni Bielefeld. The survey will form the related work chapter of his thesis. Abstract Semantic Question Answering (SQA) removes two major access requirements to the Semantic Web: the mastery of a formal query language like SPARQL and knowledge of a specific vocabulary. Because of the complexity of natural language, SQA presents difficult challenges and many ...

There are many fancy tools to edit ontologies. I like simple editors, like nano . And like any hacker, I can hack OWL ontologies in nano. The hacking implies OWL was never meant to be hacked on a simple text editor; I am not sure that is really true. Anyways, HTML5 and RDFa will do fine, and here is a brief write up. This post will not cover the basics of RDFa and does assume you already know how triples work. If not, read this RDFa primer first. The BridgeDb DataSource Ontology This example uses the BridgeDb DataSource Ontology, created ...

This Colloquium will be presented by Edgard Marx and Diego Moussallem. Edgard Marx will present the progress of his PhD titled "An Open Question Answering Framework". Billions of facts pertaining to a multitude of domains are now available on the Web as RDF data. However, accessing this data is still a difficult endeavour for non-expert users. The goal of this PhD is the development of a framework for Question Answering over Linked Data. Diego Moussallem will present a survey about machine translation using semantic web technologies as well as his future works. Although Machine Translation systems have achieved significant results int the last decade, ...

As we move towards "Linked Data Platform"[ 0 ] support, we need to provide a mechanism to modify selectively repository content which represents containers and collections. Yes, in principle, the SPARQL and Graph Store protocols provide such facilities, but there is a wide-spread reluctance to admit their suitability due to one common issue: the restrictions placed on blank node designators. Any sorts of models which involve blank nodes require special procssing in order to specify the statements to modify. We note, for this, there is no effective standard method and have considered whether the "Linked Data Patch Format" could serve ...

In this Colloquium, Tommaso Soru will present the progress of his PhD titled "Learning Metrics for Link Discovery" . The discovery of new links is essential for the construction of the Linked Data cloud. The use of links to other URIs was initially suggested by Tim Berners-Lee and is known as the 4th Linked Data Principle . The goal of this PhD is to research new approaches based on machine- and statistical-learning techniques for Link Discovery.

Tweet In the 14-09-2015 ebiquity meeting , Ankur Padia will talk about his recent work aimed at providing access control for an RDF triple store. Attribute-based Fine Grained Access Control for Triple Stores Ankur Padia, UMBC The maturation of semantic web standards and associated web-based data representations like schema.org have made RDF a popular model for representing graph data and semi-structured knowledge. However, most existing SPARQL endpoint supports simple access control mechanism preventing its use for many applications. To protect the data stored in RDF stores, we describe a framework to support attribute-based fine grained access control and explore its ...

Over the past couple of years I've written several posts that each focus on trying to answer a simple question relating to data and/or open data. I've collected them together into a list here for easier reference. I'll update the list as I write more related posts:
