AKSW Colloquium, 27.03.2017, PPO & PPM 2.0: Extending the privacy preference framework to provide finer-grained access control for the Web of Data

2017-03-27T08:13:08Z

In the upcoming Colloquium, March the 27th at 3 PM  Marvin Frommhold  will discuss the paper “PPO & PPM 2.0: Extending the Privacy Preference Framework to provide finer-grained access control for the Web of Data” by Owen Sacco and John G. Breslin published in the I-SEMANTICS ’12 Proceedings of the 8th International Conference on Semantic Systems. Abstract :  Web of Data applications provide users with the means to easily publish their personal information on the Web. However, this information is publicly accessible and users cannot control how to disclose their personal information. Protecting personal information is deemed important in use cases such as ...

Webinar: Nailing Jello to a Wall: Metrics, Frameworks, & Existing Work for Metadata Assessment

2017-03-24T23:59Z

2017-03-24, With the increasing number of repositories, standards and resources we manage for digital libraries, there is a growing need to assess, validate and analyze our metadata - beyond our traditional approaches such as writing XSD or generating CSVs for manual review. Being able to further analyze and determine measures of metadata quality helps us better manage our data and data-driven development, particularly with the shift to Linked Open Data leading many institutions to large-scale migrations. Yet, the semantically-rich metadata desired by many Cultural Heritage Institutions, and the granular expectations of some of our data models, makes performing assessment, much ...

Fearful about personal data, a personal example

2017-03-21T19:10:33Z

I was recently at a workshop on making better use of (personal) data for the benefit of specific communities.  The discussion, perhaps inevitably, ended up focusing on many of the attendees concerns around how data about them was being used. The group was asked to share what made them afraid or fearful about how personal data might be misused. The examples were mainly about use of the data by Facebook, by advertisers, as surveillance, etc. There was a view that being in control of that data would remove the fear and put the individual back in control. This same argument pervades ...



SPARQL Limit by Resource

2017-03-21T03:17:03Z

As part of work on the Attean Semantic Web toolkit, I found some time to work through limit-by-resource , an oft-requested SPARQL feature and one that my friend Kjetil lobbied for during the SPARQL 1.1 design phase. As I recall, the biggest obstacle to pursuing limit-by-resource in SPARQL 1.1 was that nobody had a clear idea of how to fit it nicely into the existing SPARQL syntax and semantics. With hindsight, and some time spent working on a prototype, I now suspect that this was because we first needed to nail down the design of aggregates and let aggregation become ...

The British Hypertextual Society (1905-2017)

2017-03-11T11:52:06Z

With their globe-spanning satellite network nearing completion, Peter Linkage reports on some of the key milestones in the history of the British Hypertextual Society. The British Hypertextual Society was founded in 1905 with a parliamentary grant from the Royal Society of London. At the time there was growing international interest in finding better ways to manage information, particularly scientific research. Undoubtedly the decision to invest in the creation of a British centre of expertise for knowledge organisation was also influenced by the rapid progress being made in Europe.



A Machine Learning Workflow

2017-03-10T19:25:55Z

I am giving a talk (in French) at the 85th edition of the ACFAS congress , May 9. I will discuss the engineering aspects of doing machine learning. But more importantly, I will discuss how Semantic Web techniques, technologies and specifications can help solving the engineering problems and how they can be leveraged and integrated in a machine learning workflow. The focus of my talk is based on my work in the field of the semantic web in the last 15 years and my more recent work creating the KBpedia Knowledge Graph at Cognonto and how they influenced our work ...

New GERBIL release v1.2.5 – Benchmarking entity annotation systems

2017-03-10T10:49:51Z

Dear all, the Smart Data Management competence center at AKSW is happy to announce GERBIL 1.2.5. GERBIL is a general entity annotation benchmarking system and offers an easy-to-use web-based platform for the agile comparison of annotators using multiple datasets and uniform measuring approaches. To add a tool to GERBIL, all the end user has to do is to provide a URL to a REST interface to its tool which abides by a given specification. The integration and benchmarking of the tool against user-specified datasets is then carried out automatically by the GERBIL platform. Currently, our platform provides results for **20 annotators** ...

Designing CSV files

2017-03-07T22:22:44Z

A couple of the projects I’m involved with at the moment are at a stage where there’s some thinking going on around how to best provide CSV files for users. This has left me thinking about what options we actually have when it comes to designing a CSV file format. CSV is a very useful, but pretty mundane format. I suspect many of us don’t really think very much about how to organise our CSV files. It’s just a table, right? What decisions do we need to make? But there are actually quite a few different options we have that might make a specific CSV ...



SADL: Semantic Application Design Language

Tweet SADL – Semantic Application Design Language Dr. Andrew W. Crapo GE Global Research  10:00 Tuesday, 7 March 2017 The Web Ontology Language (OWL) has gained considerable acceptance over the past decade. Building on prior work in Description Logics, OWL has sufficient expressivity to be useful in many modeling applications. However, its various serializations do not seem intuitive to subject matter experts in many domains of interest to GE. Consequently, we have developed a controlled-English language and development environment that attempts to make OWL plus rules more accessible to those with knowledge to share but limited interest in studying formal ...



Webinar: Data on the Web Best Practices: Challenges and Benefits

2017-03-03T23:59Z

2017-03-03, There is a growing interest in the publication and consumption of data on the Web. Government and non-governmental organizations already provide a variety of data on the Web, some open, others with access restrictions, covering a variety of domains such as education, economics, e-commerce and scientific data. Developers, journalists, and others manipulate this data to create visualizations and perform data analysis. Experience in this area reveals that a number of important issues need to be addressed in order to meet the requirements of both publishers and data consumers. In this webinar, Bernadette Farias Lóscio, Caroline Burle dos Santos Guimarães ...

Immutable preferences, economics, social media and algorithmic recommendations

2017-03-03T13:22:02Z

One of the things that encouraged me to leave economics after doing a PhD was that – at the time, and still in textbook microeconomics – the model of a person was so basic it could not encompass wants and needs that change . You, to an economist, usually look like this: “Indifference Curves” over two goods by



KBpedia Knowledge Graph 1.40: Extended Using Machine Learning

The USPTO Linked Patent Dataset release

2017-02-24T16:18:51Z

Dear all, We are happy to announce USPTO Linked Patent Dataset release. Patents are widely used to protect intellectual property and a measure of innovation output. Each year, the USPTO grants over 150, 000 patents to individuals and companies all over the world. In fact, there were more than 200, 000 patent grants issued in the US in 2013. However, accessing, searching and analyzing those patents is often still cumbersome and inefficient. Our dataset is the output of converting USPTO XML patents data into RDF from the years 2002 – 2016. This supports the integration with other data sources in ...
