Data and information in the city

For a while now I've been in the habit of looking for data as I travel to work or around Bath. You can't really work with data and information systems for any length of time without becoming a little bit obsessive about numbers or becoming tuned into interesting little dashboards: Local data dashboard spotted in St Ives

AKSW Colloquium, 17-08-2015, Relational Machine Learning for Knowledge Graphs, Zoo Keeper, Apache Mesos

Relational Machine Learning for Knowledge Graphs In this colloquium Patrick Westphal will present the paper "A Review of Relational Machine Learning for Knowledge Graphs" by Nickel, Murphy, Tresp and Gabrilovich. Abstract: Relational machine learning studies methods for the statistical analysis of relational, or graph-structured, data. In this paper, we provide a review of how such statistical models can be "trained" on large knowledge graphs, and then used to predict new facts about the world (which is equivalent to predicting new edges in the graph). In particular, we discuss two different kinds of statistical relational models, both of which can scale ...

Michael Röder at AKSW Colloquium, Monday, 10th August 2015, 3pm

Crawling the Linked Open Data Cloud by Michael Röder In the recent years the Linked Open Data Cloud matured to support various applications, e.g., question answering, knowledge inference or database enrichment. Such applications have to be supported by the recent data, which is impossible to retrieve without constant crawling, due to the dynamic nature of the World Wide Web and the cloud as a part of it. On this colloquium Michael is going to talk about the state of the art for Linked Data Crawling as well as the future work that will be done by Ivan Ermilov, Axel-Cyrille Ngonga Ngomo ...

How the PoolParty Semantic Suite is learning to speak 40+ languages

Business is becoming more and more globalised, and enterprises and organisations are acting in several different regions and thus facing more challenges of different cultural aspects as well as respective language barriers. Looking at the European market, we even see 24 working languages in EU28, which make cross-border services considerably complicated. As a result, powerful language technology is needed, and intense efforts have already been taken in the EU to deal with this situation and enable the vision of a multilingual digital single market (a priority area of the European Commission this year, see: http://ec.europa.eu/priorities/digital-single-market/ ).
