AKSW Colloquium, 04.07.2016. Big Data, Code Quality.

On the upcoming Monday (04.07.2016), AKSW group will discuss topics related to Semantic Web and Big Data as well as programming languages and code quality. In particular, the following papers will be presented: S2RDF: RDF Querying with SPARQL on Spark by Alexander Schätzle et al. Presented by: Ivan Ermilov RDF has become very popular for semantic data publishing due to its flexible and universal graph-like data model. Yet, the ever-increasing size of RDF data collections makes it more and more infeasible to store and process them on a single machine, raising the need for distributed approaches. Instead of building a ...

AKSW Colloquium, 27.06.2016, When owl:sameAs isn’t the Same + Towards Versioning for Arbitrary RDF Data

In the next Colloquium, June the 27th at 3 PM, two papers will be presented: When owl:sameAs isn't the Same: An Analysis of Identity in Linked Data André Valdestilhas will present the paper "When owl:sameAs isn't the Same: An Analysis of Identity in Linked Data" by Halpin et al. [ PDF ]: Abstract : In Linked Data, the use of owl:sameAs is ubiquitous in interlinking data-sets. There is however, ongoing discussion about its use, and potential misuse, particularly with regards to interactions with inference. In fact, owl:sameAs can be viewed as encoding only one point on a scale of similarity, one that is ...

New Paper: "Using the Semantic Web for Rapid Integration of WikiPathways with Other Biological Online Data Resources"

Andra Waagmeester published a paper on his work on a semantic web version of the WikiPathways (doi: 10.1371/journal.pcbi.1004989 ). The paper outlines the design decisions, shows the SPARQL endpoint , and several examples SPARQL queries. These include federates queries, like a mashup with DisGeNET (doi: 10.1093/database/bav028 ) and EMBL-EBI's Expression Atlas . That results in nice visualisations like this: If you have the relevant information in the pathway, these pathways can help a lot in helping understanding of what is biologically going on. And, of course, used for exactly that a lot. Press release Because press releases have become an ...

The state of open licensing

I spend a lot of time reading through licences and terms & conditions. Much more so than I thought I would when I first started getting involved with open data. After all, I largely just like making things with data. But there's still so much data that is

From services to products

Over the course of my career I've done a variety of consulting projects as both an employee and freelancer. I've helped found and run a small consulting team. And, through my experience leading engineering teams, some experience of designing products and platforms. I've been involved in a few discussions, particularly over the last 12 months or so, around how to generate repeatable products off the back of consulting engagements. I wanted to jot down a few thoughts here based on my own experience and a bit of background reading. I don't claim to have any special insight or expertise, but the topic is one ...
