Discovering Meaningful Connections between Resources in the Web of DataLaurens De Vocht
Slides of LDOW2013 presentation, May 14th, Rio De Janeiro, Brazil
We will show that semantically annotated paths lead to discovering meaningful, non-trivial relations and connections between multiple resources in large online datasets such as the Web of Data. Graph algorithms have always been key in pathfinding applications (e.g., navigation systems). They make optimal use of available computation resources to find paths in structured data. Applying these algorithms to Linked Data can facilitate the resolving of complex queries that involve the semantics of the relations between resources. In this paper, we introduce a new approach for finding paths in Linked Data that takes into account the meaning of the connections and also deals with scalability. An efficient technique combining pre-processing and indexing of datasets is used for finding paths between two resources in largedatasets within a couple of seconds. To demonstrate our approach, we have implemented a testcase using the DBpedia dataset.
Aligning Web Collaboration Tools with Research Data for ScholarsLaurens De Vocht
Resources for research are not always easy to explore, and
rarely come with strong support for identifying, linking and
selecting those that can be of interest to scholars. In this
work we introduce a model that uses state-of-the-art semantic technologies to interlink structured research data and data from Web collaboration tools, social media and Linked Open Data. We use this model to build a platform that connects scholars, using their proles as a starting point to explore novel and relevant content for their research. Scholars can easily adapt to evolving trends by synchronizing new social media accounts or collaboration tools and integrate then with new datasets. We evaluate our approach by a scenario of personalized exploration of research repositories where we analyze real world scholar profiles and compare them to a reference profile.
Researcher Profiling based on Semantic Analysis in Social NetworksLaurens De Vocht
We propose a framework to address an important challenge in the context of the ongoing adoption of the “Web 2.0” in science and research, often referred to as “Research 2.0”. Microblogging is one of the trends with increasing leverage. The challenge in this thesis is to connect users of microblogging services such as Twitter based on specific common entities that are representative and truly matter to them. We investigated the possibilities of using social data for locating an expert who shares a very specific research topic. To enrich and verify this social data we link such content to existing open data provided by the online community. We are using semantic technologies (RDF ,SPARQL), com- mon ontologies (SIOC, FOAF, DublinCore, SWRC) and Linked Data (DBpedia, GeoNames, CoLinDa) to extract and mine the data about scientific conferences out of context of microblogs. We are identifying users related to each other based on entities such as topics (tags), events, time, locations and persons (mentions). As a proof-of-concept we explain, implement and evaluate such a researcher profiling use case. It involves the development of a framework that focuses on the proposition of researches based on topics and conferences they have in common. This framework provides an API that allows quick access to the analyzed information. A demonstration application: “Researcher Affinity Browser” shows how the API supports developers to build rich internet applications for Research 2.0. This application also intro- duces the concept “affinity” that exposes the implicit proximity between entities and users based on the content users produced. The usability of a demonstration application and the usefulness of the framework itself are investigated with an explicit evaluation question- naire. This user feedback lead to important conclusions about successful achievements and opportunities to further improve this effort.

A Framework Concept for Profiling Researchers on Twitter using the Web of DataLaurens De Vocht
Based upon findings and results from our recent research we propose a generic frame-
work concept for researcher profiling with appliance to the areas of ”Science 2.0” and ”Research 2.0”. Intensive growth of users in social networks, such as Twitter generated a vast amount of information. It has been shown in many previous works that social networks users produce valuable content for profiling and recommendations. Our research focuses on identifying and locating experts for specific research area or topic. In our approach we apply semantic technologies like (RDF, SPARQL), common vocabularies (SIOC , FOAF, MOAT, Tag Ontology) and Linked Data (GeoNames , COLINDA).
Effect of Heuristics on Serendipity in Path-Based Storytelling with Linked DataLaurens De Vocht
Path-based storytelling with Linked Data on the Web provides users the ability to discover concepts in an entertaining and educational way. Given a query context, many state-of-the-art pathfinding approaches aim at telling a story that coincides with the user’s expectations by investigating paths over Linked Data on the Web. By taking into account serendipity in storytelling, we aim at improving and tailoring existing approaches towards better fitting user expectations so that users are able to discover interesting knowledge without feeling unsure or even lost in the story facts. To this end, we propose to optimize the link estimation between - and the selection of facts in a story by increasing the consistency and relevancy of links between facts through additional domain delineation and refinement steps. In order to address multiple aspects of serendipity, we propose and investigate combinations of weights and heuristics in paths forming the essential building blocks for each story. Our experimental findings with stories based on DBpedia indicate the improvements when applying the optimized algorithm.

Process-oriented reactive service architecturePeter Hilton
Reactive application development gives us better ways to build scalable applications, but often together with a micro-services jigsaw puzzle. Decoupled teams can rapidly deliver decoupled services, but you still need to piece together an end-to-end system. This presentation introduces an alternative way to think about and architect reactive applications using workflow tools.
Modern workflow management tools enable a convenient process-oriented approach to service orchestration that is itself reactive. More importantly, process management technology provides two key features that hand-coded applications typically lack: persistent execution state and an editable graphical process representation that you can use to define and adjust service orchestration. After learning how to coordinate micro-services, you will also and how to use the same system to orchestrate micro-service-like human workers. It turns out that with the right platform, human actors can also be reactive services, and participate in the same architecture.

Margir sjálfboðaliðar vita mjög lítið um kristna trú. Það varð ákv trúarhefðarrof og þau sem voru börn þegar þetta var eru nú fullorðið fólk. Marga vantar jafnvel grundvallarvitneskju. T.d. hver er Jesú, hvað er Biblía. Sjálfboðaliðastarfið hefur því um leið ákv trúboðsáhrif.
Svar: fræðsla um kristna trú í samtímanum
2. Sjálfsmynd kirkjunnar er ekki aðlaðandi fyrir sjálfboðaliða
Þessu þarf að mæta með nýjum kirkjuskilningi og innleiða nýja sýn svo viðmót kirkjunnar sé áhugavert sem vettvangur þátttöku sem leiði til lífsfyllingar og þroska sem gerir samfélaginu gott.
Átök milli launaðra og ólaunaðra starfsmanna snúast um peninga, hvernig ákvarðanir eru teknar og hver tekur þær. Hvert eiga sjálfboðaliðar að snua sér þegar upp koma vandamál?
Svar: Bæta menntun presta sem í dag miðar ekki að því að þeir verði hæfari í að byggja upp sjálfboðaliðastarf. Meiri áhersla á að læra grísku og hebresku en tungumál mannsins Mikilvægt er að breyta sjálfsmynd kirkjunnar og að gera hana áhugaverðari í augum sjálfboðaliða.
#1 Sjálfboðin þjónusta snýst um kirkjuþátttöku og að fá að rækta sjálfan sig í umhverfi trúarinnar.
#2 Þátttökukirkjan byggir á nýju viðhorfi sem virðir þarfir, áhuga og hæfileika fólks í kirkjustarfi.
#3 Markmiðið er að breyta kirkjuskilningi og innleiða nýja sýn.
#4 Skrefið frá umönnunarkirkju yfir í þátttökukirkju verður að stíga, eigi kirkjan að lifa af.
