Two AKSW Papers at ESWC 2015

We are very pleased to announce that two of our papers were accepted for presentation as full research papers at ESWC 2015. Automating RDF Dataset Transformation and Enrichment (Mohamed Ahmed Sherif, Axel-Cyrille Ngonga Ngomo, and Jens Lehmann) With the adoption of RDF across several domains, come growing requirements pertaining to the completeness and quality of RDF datasets. Currently, this problem is most commonly addressed by manually devising means of enriching an input dataset. The few tools that aim at supporting this endeavour usually focus on supporting the manual definition of enrichment pipelines. In this paper, we present a supervised learning ...

AKSW Colloquium, 03-23-2015, Query Tree Learner and From CPU bringup to IBM Watson

From CPU bring up to IBM Watson by Kay Müller, visiting researcher, IBM Ireland Working in a corporate environment like IBM offers many different opportunities to work on the bleeding edge of research and development. In this presentation Kay Müller, who is currently a Software Engineer in the IBM Watson Group, is going to give a brief overview of some of the projects he has been working on in IBM. These projects range from a CPU bring up using VHDL to the design and development of a semantic search framework for the IBM Watson system. Git Triple Store by Natanael ...

Tiny micro servo 9g and Duemilanove w/ ATmega168

It's eons since I messed with an Arduino, and I've forgotten it all. All I have handy is a Duemilanove with ATmega168 and the newish version of the Arduino IDE doesn't have Duemilanove ATmega168 as an option. Following

DCMI Webinar: "Approaches to Making Dynamic Data Citable: Recommendations of the RDA Working Group"

2015-03-16, Being able to reliably and efficiently identify entire or subsets of data in large and dynamically growing or changing datasets constitutes a significant challenge for a range of research domains. In order to repeat an earlier study, to apply data from an earlier study to a new model, we need to be able to precisely identify the very subset of data used. While verbal descriptions of how the subset was created (e.g. by providing selected attribute ranges and time intervals) are hardly precise enough and do not support automated handling, keeping redundant copies of the data in question does ...

Open Semantic Framework 3.3 Released

Structured Dynamics is happy to announce the immediate availability of the Open Semantic Framework version 3.3. This new release of OSF lets system administrators choose between two different communication channels to send SPARQL queries to the triple store: HTTP ODBC In OSF 3.1, the only communication channel available was a ODBC channel using the iODBC drivers. In OSF 3.2, the only communication channel available was a HTTP channel. What we did with OSF 3.3 is to let the system administrator choose between the two. Quick Introduction to the Open Semantic Framework What is the Open Semantic Framework? The Open Semantic ...

ALIGNED project kick-off

ALIGNED , AKSW's new H2020-funded project, kicked off in Dublin. The project brings together computer science researchers, companies building data-intensive systems and information technology, and academic curators of large datasets in an effort to build IT systems for aligned, co-evolving software and data lifecycles. These lifecycles will support automated testing, runtime data quality analytics, model-generated extraction and human curation interfaces. AKSW will lead the data quality engineering part of ALIGNED, controlling the data lifecycle and providing integrity and verification techniques, using state-of-the-art tools such as RDFUnit and upcoming standards like W3C Data Shapes . In this project, we will ...

AKSW Colloquium: Tommaso Soru and Martin Brümmer on Monday, March 2 at 3.00 p.m.

On Monday, 2nd of March 2015, Tommaso Soru will present ROCKER, a refinement operator approach for key discovery. Martin Brümmer will then present NIF annotation and provenance - A comparison of approaches. Tommaso Soru - ROCKER - Abstract As within the typical entity-relationship model, unique and composite keys are of central importance also when their concept is applied on the Linked Data paradigm. They can provide help in manifold areas, such as entity search, question answering, data integration and link discovery. However, the current state of the art does not count approaches able to scale while relying on a correct ...
