Call for Papers ESWC 2021 Data Dynamics, Quality, and Trust

Description

This track addresses two overlapping problem spaces: on the one hand, data dynamics and, on the other hand, quality and trust.

Data dynamics refers to a current and significant trend towards the continuous and fast production of data as well as the diffuse need to consume it in a timely fashion (a.k.a., being reactive) to act in time. This trend is highly visible in IoT, Industry 4.0, and Social Media, but it is emerging in many other industries. In this scenario, there is a clear need for new theoretical, analytical, and empirical solutions tailored to fast-evolving and heterogeneous data. The Semantic Web research landscape has already developed some of them in investigating Stream Reasoning, RDF streams, and extensions of SPARQL for data streams and complex events but there is still a long way to go before creating real-world impact.

Data quality becomes challenging with the increasing sizes and dynamicity of data. Many existing approaches mostly contain a customized data quality functionality to detect and analyze data quality issues within their own domain. However, this process is both data-intensive and computing-intensive and it is a challenge to develop fast and efficient algorithms that can handle large scale and dynamic knowledge graphs (KGs). New algorithms and metrics have to be designed, in particular, in order to deal with novel requirements related on one hand to the variety, volume and velocity issues of KGs and on the other hand to their structural characteristics. Moreover, none of the current approaches use the assessment to ultimately improve the quality in the long run.

In this call for paper, we invite novel contributions that address one of the two spaces or both at the same time.

Negative Results

As a new theme in 2021, ESWC also encourages the submission of negative results papers, which we also encourage in this track. Specific instructions for negative results papers can be found here.
