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

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

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

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)

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

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

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

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 ...
