Wikimedia Deutschland ist als Verein aus der Wikipedia-Bewegung hervorgegangen und hat unter anderem das Ziel, sich für freies Wissen stark zu machen. Freie Bildung als integraler Bestandteil von freiem Wissen kommt als Ergebnis in den schwächelnden Wikimedia-Projekten Wikibooks und Wikiversity jedoch zu kurz.

Semantic data fuels many different applications, but is still lacking proper integration into programming languages. Untyped access is error-prone while mapping approaches cannot fully capture the conceptualization of semantic data.

Recent developments in the SemGIS project In part one an update on recent developments in the SemGIS project concerning automated mapping approaches of geospatial data into the semantic web is given.

The efficiency of SPARQL query evaluation against Linked Open Data may benefit from schema-based indexing. However, many data items come with incomplete schema information or lack schema descriptions entirely. We outline an approach to an indexing of linked data graphs based on schemata induced through Formal Concept Analysis.

The Resource Description Framework (RDF) is a triple based representation of directed graphs with labelled edges. With the emergence of RDF graphs special databases, called RDF stores, were developed. In order to query graphs, which are stored in these RDF stores, the query language SPARQL Protocol And Query Language (SPARQL) is used.

Our objective is to identify and assess gender bias related to professions in the results of collaborative community work. We present the results of studies in which we characterize the gender inequality present over the three dimensions: redirections, images, and people mentioned in the articles.

To help in overcoming a shortage of citation information for the German social sciences, we contribute an approach for extracting author names from reference sections. Instead of relying on small amounts of manually labeled data, we use a distantly supervised approach in combination with the widely used probabilistic framework of conditional random fields.

During the development of a distributed database for big data, small datasets are used to test the implementation and to evaluate alternative solutions. These small datasets have the advantage that evaluation results are produced more quickly and the implementation progresses faster. When the database is tested with large datasets, several design decisions based on the experiments with the small datasets can lead to a poor performance or unstable database. In this talk some of these wrong design decisions during the implementation of the distributed RDF store Koral are presented and how they could be improved.

How can we recognize social roles of users, given a completely novel social network? We present a transfer learning approach based on feature transformation, in order to learn knowledge from networks that we know well, and apply the knowledge to predict user roles in other networks that are new to us. We implement our approach and evaluate it with real networks.

Interaction on the web or mobile platform is done by humans on devices designed by humans using interfaces that too has the human touch to it. And thats why this talk focus on understanding how the human signal responds to different interaction methods and how we can use these measurements to improve the existing framework or create interfaces or platforms for those who are challenged to use the conventional interaction methods.
