Prof. Jens Lehmann invited the speaker to the bi-weekly “SDA colloquium presentations”. 20-30 researchers and students from SDA attended. The goal of his visit was to exchange experience and ideas on biometrics applications in daily life, including face recognition, fingerprints, privacy and many more. Apart from presenting various use-cases where biometrics has helped scientists to get useful insights from image analysis and processing and row data, Prof. Dr. Saeed shared with our group future research problems and challenges related to this research area and gave a talk on “Biometrics in everyday life”.
As part of a national BMBF funded project, Prof. Saeed (BUT) is cooperating currently with Fraunhofer IAIS in the field of cognitive engineering, and as an outcome of this visit, we expect to strengthen our research collaboration networks with WUT and BUT, mainly on combining semantic knowledge and Ubiquitous Computing and its applications; Emotion Detection and Kansei Engineering.
Simultaneously, this talk was a continuous networking within EU H2020 LAMBDA project (Learning, Applying, Multiplying Big Data Analytics) and as part of this eventDr. Valentina Janev from the Institute “Mihajlo Pupin” (PUPIN) was attending the SDA meeting to investigate further networking with potential partners from Poland as well. Among other points, co-organizing coming conferences and writing joint-research papers have been discussed.



Invited talk by Dr. Anastasia Dimou

🗓 2018-04-19    ✍ Gezim Sejdiu

On Wednesday, 21st of March Anastasia Dimou from the Internet Technology & Data Science Lab visited SDA and gave a talk entitled “High Quality Linked Data Generation from Heterogeneous data”

Anastasia Dimou is a Post-Doc Researcher at the Internet Technology & Data Science Lab at Gent University, Belgium. Anastasia joined the IDLab research group in February 2013. Her research expertise lies in the area of the Semantic Web, Linked Data Generation and Publication, Data Quality and Integration, Knowledge Representation and Management. She has broad experience on Semantic Wikis and Classification. As part of her research, she investigated a uniform language for describing the mapping rules for generating high-quality Linked Data from multiple heterogeneous data formats and access interfaces and she also conducted research on Linked Data generation and publishing workflows. Her research activities led to the development of the RML tool chain (RMLProcessor, RMLEditor, RMLValidator, and RMLWorkbench). Anastasia has been involved in different national and l research projects and publications.

Prof. Jens Lehmann invited the speaker to the bi-weekly “SDA colloquium presentations”. The goal of her visit was to exchange experience and ideas on RML tools specialized for data quality and on the fly mapping, including heterogeneous dataset mapping into LOD. Apart from presenting various use cases where RML tools were used, she introduced a declarative RML serialization which models the mapping rules using the well-known yaml language. Anastasia shared with our group future research problems and challenges related to this research area.

In her talk, she introduced a full workflow aka the RML tool chain which models components of an RML mapping lifecycle. She discussed its application to the structure of heterogeneous data sources. Anastasia Dimou mentioned that adding support for data quality during the mapping shall allow users to efficiently explore a structured search space to enable the future violations not only map the range of the known domain but also help to discover new knowledge from the existing knowledge base worth mapping.

During the visit, SDA core research topics and main research projects were presented in a (successful!) attempt to find an intersection on the future collaborations with Anastasia and her research group.

As an outcome of this visit, we expect to strengthen our research collaboration networks with the Internet Technology & Data Science Lab at UGent, mainly on combining semantic knowledge for exploratory and mapping tools and apply those techniques for a very large-scale KG using our distributed analytics framework SANSA and DBpedia.

Svitlana shared with our group future research problems and challenges related to this research area and shown that the Semantic Coherence will provide more insight and meaningful results to the conversational browsing scenario. In this talk, she introduces the task of conversational browsing that goes beyond Question Answering. A framework which models components of a conversational browsing system has been presented and discussed its application to the structure of a Knowledge Graph (KG). She mentioned that adding support for conversational browsing functionality shall allow users to efficiently explore a structured search space to enable the future conversational search systems not only answer a range of questions but also help to discover questions worth asking. During the visit, SDA core research topics and main research projects were presented in an attempt to find an intersection on the future collaborations with Svitlana and her research group. As an outcome of this visit, we expect to strengthen our research collaboration networks with the Institute of Information Business at WU Wien, mainly on combining semantic knowledge for exploratory and conversation search and apply those techniques for a very large-scale KG using our distributed analytics framework SANSA.
