DocBook and HTML 5(.x)

HTML 5(.x) today reminds me a lot of DocBook 1(.x) twenty years ago. That's neither criticism nor compliment, merely observation.

Big Structures: Where the Semantic Web Meets Artificial Intelligence

Mike Bergman just published the second part 1 of his series of blog posts that summarize the evolution of the Semantic Web in the last decade, and how our experience of the last 7 years of research in that field has led to these observations. The second part of that series is: Big Structure: At The Nexus of Knowledge Bases, the Semantic Web and Artificial Intelligence . He continues to outline some issues with the Semantic Web, but more importantly how it fits in a much broader ecosystem, namely KBAI (Knowledge Based AI). He explains the difference between data integration ...

DC-2014 post-conference workshop: "Training the Trainers of Linked Data"

2014-07-22, DCMI and the Texas Digital Library invite you to register for this day-long, hands-on "Training the Trainers of Linked Data" post-conference workshop to be held on Saturday, October 11, 2014. Linked Data has gained momentum, and practitioners are eager to use its principles to derive more value from metadata. Available handbooks and training materials focus on an audience with a computer science background. However, people with a non-technical education find it hard to understand what Linked Data can mean for them. This full-day, hands-on workshop will provide an overview of methods and case studies from the handbook "Linked Data ...

New UMBEL Concept Noun Tagger Web Service & Other Improvements

Last week, we released the UMBEL Concept Plain Tagger web service endpoint . Today we are releasing the UMBEL Concept Noun Tagger. This noun tagger uses UMBEL reference concepts to tag an input text, and is based on the plain tagger , except as noted below. The noun tagger uses the plain labels of the reference concepts as matches against the nouns of the input text. With this tagger, no manipulations are performed on the reference concept labels nor on the input text except if you specify the usage of the stemmer . Also, there is NO disambiguation performed by ...

When did linking begin?

Pointing somewhere with a dereferenceable address, in the twelfth (or maybe fifth) century.

Preprint: Interpreting Medical Tables as Linked Data to Generate Meta-Analysis Reports

Tweet Varish Mulwad, Tim Finin and Anupam Joshi, Interpreting Medical Tables as Linked Data to Generate Meta-Analysis Reports , 15th IEEE Int. Conf. on Information Reuse and Integration, Aug 2014. Evidence-based medicine is the application of current medical evidence to patient care and typically uses quantitative data from research studies. It is increasingly driven by data on the efficacy of drug dosages and the correlations between various medical factors that are assembled and integrated through meta-analyses (i.e., systematic reviews) of data in tables from publications and clinical trial studies. We describe a important component of a system to automatically produce ...

Notes on public talks

Massimo and I worked together on two posters about automatic provenance capturing for research publications and we won the ESIP FUNding Friday award. What left unforgettable to me, however, is the great lesson I learnt from giving the 2 minute pitch in front of the ESIP folks. During the 2 minutes talk, I just could not help staring at the two posters we printed and made on the day before and that morning. Now I know the reason - it's because I only practiced my speech with one of the posters displayed on my laptop. For the other poster, I ...

:BaseKB offered as a better Freebase version

Tweet In The trouble with DBpedia , Paul Houle talks about the problems he sees in DBpedia, Freebase and Wikidata and offers up :BaseKB as a better "generic database" that models concepts that are in people's shared consciousness. :BaseKB is a purified version of Freebase which is compatible with industry-standard RDF tools. By removing hundreds of millions of duplicate, invalid, or unnecessary facts, :BaseKB users speed up their development cycles dramatically when compared to the source Freebase dumps. :BaseKB is available for commercial and academic use under a CC-BY license. Weekly versions ( :BaseKB Now ) can be downloaded from ...

From Taxonomies over Ontologies to Knowledge Graphs

With the rise of linked data and the semantic web, concepts and terms like 'ontology', 'vocabulary', 'thesaurus' or 'taxonomy' are being picked up frequently by information managers, search engine specialists or data engineers to describe 'knowledge models' in general. In many cases the terms are used without any specific meaning which brings a lot of people to the basic question: What are the differences between a taxonomy, a thesaurus, an ontology and a knowledge graph? This article should bring light into this discussion by guiding you through an example which starts off from a taxonomy, introduces an ontology and finally exposes a knowledge graph ...

New UMBEL Concept Tagger Web Service

We just released a new UMBEL web service endpoint and online tool: the Concept Tagger Plain. This plain tagger uses UMBEL reference concepts to tag an input text. The OBIE (Ontology-Based Information Extraction) method is used, driven by the UMBEL reference concept ontology. By plain we mean that the words (tokens) of the input text are matched to either the preferred labels or alternative labels of the reference concepts. The simple tagger is merely making string matches to the possible UMBEL reference concepts. This tagger uses the plain labels of the reference concepts as matches against the input text. With ...
