AKSW Colloquium, 09.05.2016: Hebrew MMoOn inventory, federated SPARQL query processing

In this week's colloquium Bettina Klimek will give a practice talk of the paper ' Creating Linked Data Morphological Language Resources with MMoOn - The Hebrew Morpheme Inventory ', which she will present at the LREC conference 2016 , 23-28 May 2016, Slovenia, Portorož. Abstract The development of standard models for describing general lexical resources has led to the emergence of numerous lexical datasets of various languages in the Semantic Web. However, there are no models that describe the domain of morphology in a similar manner. As a result, there are hardly any language resources of morphemic data available in ...

chmod 000 Freebase

Tweet He's dead, Jim. Google recently shut down the query interface to Freebase . All that is left of this innovative service is the ability to download a few final data dumps. Freebase was launched nine years ago by Metaweb as an online source of structured data collected from Wikipedia and many other sources, including individual, user-submitted uploads and edits. Metaweb was acquired by Google in July 2010 and Freebase subsequently grew to have more than 2.4 billion facts about 44 million subjects. In December 2014, Google announced that it was closing Freebase and four months later it became read-only. ...

DCMI Webinar: Modeling and Publishing of Controlled Vocabularies for the UNESKOS Project [Presented in Spanish]

2016-05-02, DCMI/ASIS&T Webinar: This webinar with Juan Antonio Pastor Sánchez, University of Murcia, presents the modeling and publishing process of the vocabularies for the UNESKOS project by applying Semantic Web technologies. More specifically, the vocabularies represented are the UNESCO Thesaurus and the Nomenclature for fields of Science and Technology. Both vocabularies are published as RDF datasets with a structure that allows its query and reuse according to the principles of Linked Open Data. The webinar will demonstrate the application of ISO-25964 standard to represent the UNESCO thesaurus using SKOS and the ISO-THES ontology. Technological solutions used for the project will ...

Representing and Reasoning with Temporal Properties/Relations in OWL/RDF

Tweet Representing and Reasoning with Temporal Properties/Relations in OWL/RDF Clare Grasso 10:30-11:30 Monday, 2 May 2016, ITE346 OWL ontologies offer the means for modeling real-world domains by representing their high-level concepts, properties and interrelationships. These concepts and their properties are connected by means of binary relations. However, this assumes that the model of the domain is either a set of static objects and relationships that do not change over time, or a snapshot of these objects at a particular point in time. In general, relationships between objects that change over time (dynamic properties) are not binary relations, since they involve ...

AKSW Colloquium, 25.04.2016, DISPONTE, Workbench for Big Data Dev

In this colloquium, Frank Nietzsche will present his master thesis titled "Game Theory- distributed solving" Game theory analyzes the behavior of individuals in complex situations. One popular game in Europe and North America with such a complex situation is Skat . For the analysis of the game, the counterfactual regret minimization algorithm (CFR algorithm) was applied. Unfortunately, there is no guarantee that the algorithm works in three-person games. In general, it is difficult to solve three-person games. In addition, the algorithm calculates only a epsilon-Nash equilibrium. But for Skat, the Perfect Bayesian equilibrium would be a better solution. In fact, ...

AKSW Colloquium, 18.04.2016, DISPONTE, Workbench for Big Data Dev

In this week's Colloquium, today 18th of April at 3 PM, Patrick Westphal will present the paper ' Probabilistic Description Logics under the Distribution Semantics ' by Riguzzi et. al. Abstract Representing uncertain information is crucial for modeling real world domains. In this paper we present a technique for the integration of probabilistic information in Description Logics (DLs) that is based on the distribution semantics for probabilistic logic programs. In the resulting approach, that we called DISPONTE, the axioms of a probabilistic knowledge base (KB) can be annotated with a real number between 0 and 1. A probabilistic knowledge base ...

AKSW Colloquium, 11.04.2016, METEOR with DBnary

In this week's Colloquium, today 11th of April at 3 PM, Diego Moussallem will present the paper by Zied Elloumi et al. titled "METEOR for Multiple Target Languages using DBnary." [ PDF ]. Abstract This paper proposes an extension of METEOR, a well-known MT evaluation metric, for multiple target languages using an in-house lexical resource called DBnary (an extraction from Wiktionary provided to the community as a Multilingual Lexical Linked Open Data). Today, the use of the synonymy module of METEOR is only exploited when English is the target language (use of WordNet). A synonymy module using DBnary would allow ...

In this week's Colloquium, today 4th of April at 3 PM, Lorenz Bühmann will present the paper by Galárraga et al. titled "AMIE: Association Rule Mining under Incomplete Evidence in Ontological Knowledge Bases." [ PDF ]. Abstract Recent advances in information extraction have led to huge knowledge bases (KBs), which capture knowledge in a machine-readable format. Inductive Logic Programming (ILP) can be used to mine logical rules from the KB. These rules can help deduce and add missing knowledge to the KB. While ILP is a mature field, mining logical rules from KBs is different in two aspects: First, current ...
