A knowledge graph for science

The document-oriented workflows in science have reached (or already exceeded) the limits of adequacy as highlighted for example by recent discussions on the increasing proliferation of scientific literature and the reproducibility crisis. Now it is possible to rethink this dominant paradigm of document-centered knowledge exchange and transform it into knowledge-based information flows by representing and expressing knowledge through semantically rich, interlinked knowledge graphs. The core of the establishment of knowledge-based information flows is the creation and evolution of information models for the establishment of a common understanding of data and information between the various stakeholders as well as the integration of these technologies into the infrastructure and processes of search and knowledge exchange in the research library of the future. By integrating these information models into existing and new research infrastructure services, the information structures that are currently still implicit and deeply hidden in documents can be made explicit and directly usable. This has the potential to revolutionize scientific work because information and research results can be seamlessly interlinked with each other and better mapped to complex information needs. Also research results become directly comparable and easier to reuse.

Sören has made contributions to semantic web technologies, knowledge engineering, software engineering, as well as databases and information systems. Sören is author (respectively co-author) of over 100 peer-reviewed scientific publications. He received several awards, such as the ESWC 7-year best paper award, the or the OpenCourseware Innovation award. He led / is leading several large-scale collaborative research projects such as the European Union’s H2020 flagship project BigDataEurope. Sören is co-founder of several high-impact research and community projects such as the Wikipedia semantification project DBpedia, the OpenCourseWare authoring platform SlideWiki.org or the scholarly communication metadata platform OpenResearch.org. The technology Sören develops with his team fuels many industrial applications.

Collective Intelligence: An Influence Analysis of Diversity and Collective Cardinality on Collective Performance

This talk presents a general framework to demonstrate the prominent role of diversity in the effectiveness of collective performance. There appears to be ample evidence that diversity is one of the essential criteria of which a collective to be intelligent. Intuitively, a collective involving diverse individuals may add new information, new perspectives, and so forth on the problem that needs to be solved. Moreover, the diversity of individual solutions to the given problem has been proven helpful in eliminating the phenomenon of correlated errors. We have defined the objectives to investigate the influence of the latter kind of diversity on the collective performance by taking into account the collective cardinality. Our findings qualify the positive impact of diversity on collective performance. Particularly, collectives with higher diversity levels will lead to better collective performances. Subsequently, expanding the collective cardinality that causes an increase in its diversity will also be positively associated with the collective performance. With some restrictions, the hypothesis "The more diverse the collective, the higher the collective performance" is formally proved. Furthermore, the conditions under which increasing the cardinality of a collective will cause its diversity to be increased (or decreased) are worked out.

Observing Global Social Dynamics through Event Monitoring

Today everybody can be informed about anything and everything. Information is available online presenting facts, expressing different views, giving more or less credible data. We are all interconnected and co-exist in the same global environment, interacting on different levels. Electronic media, via physical network of devices and electronic interconnections between them, is making it very tangible. Crossing barriers between different countries, cultures, languages, life styles etc. is today a part of normal life. We cannot pretend it is not happening thus we suggest to put efforts in becoming more aware of the environment we all live in via monitoring of worldwide events. Focusing on the events reported in electronic media, we see several challenges that motive research on text data analytics. To contribute to that end, we have developed a system http://EventRegistry.org for observing events around the world in real-time via collecting information from over 300,000 news and social media sources. The underlying methods for text mining and data analytics enable handling large amount of textual data across different languages, enriching data with semantic information, extracting information and identifying events, streaming information about events in open data formats, organizing and representing events to support observing global social dynamics. The talk will discuss challenges and research/technical solutions.
