AKSW Colloquium, 23-11-2015, CVtec and Patty

Andreas NareikeCVtec and model-driven semantification by Andreas Nareike

In this presentation, I will give a short introduction to our project CVtec (http://www.cv-tec.de/). CVtec is concerned with knowledge management for technical facilities and uses methods of model-driven software development. Although CVtec uses relational databases to persist data right now, we are researching possibilities to move towards a Semantic data model. I will give an overview of our different approaches and hope to get some valuable feedback.

René SpeckRené Speck will present Patty: A Taxonomy of Relational Patterns with Semantic Types by Ndapandula Nakashole, Gerhard Weikum, Fabian SuchanekMax Planck Institute for Informatics,  Saarbücken, Germany

This paper presents PATTY: a large resource for textual patterns that denote binary relations between entities. The patterns are semantically typed and organized into a subsumption taxonomy. The PATTY system is based on efficient algorithms for frequent itemset mining and can process Web-scale corpora. It harnesses the rich type system and entity population of large knowledge bases. The PATTY taxonomy comprises 350,569 pattern synsets. Random-sampling-based evaluation shows a pattern accuracy of 84.7%. PATTY has 8,162 subsumptions, with a random-sampling-based precision of 75%. The PATTY resource is freely available for interactive access and download.
