1st Call for Systems - ISWC 2019 Semantic Web Challenge on Tabular Data to Knowledge Graph Matching

--Apologies for cross-posting--


This is the 1st call for systems for the ISWC 2019 Semantic Web Challenge
on Tabular Data to Knowledge Graph Matching:
http://www.cs.ox.ac.uk/isg/challenges/sem-tab/

Tabular data to Knowledge Graph (KG) matching is the process of assigning
semantic tags from Knowledge Graphs (e.g., Wikidata or DBpedia) to the
elements of the table. This task however is often difficult in practice due
to metadata (e.g., table and column names) being missing, incomplete or
ambiguous.

This challenge aims at benchmarking systems dealing with the tabular data
to KG matching problem, so as to facilitate their comparison on the same
basis and the reproducibility of the results.


Challenge Tasks
----------------------

The challenge includes the following tasks organised into several
evaluation rounds:

    - Assigning a semantic type (e.g., a KG class) to a column: CTA task.
    - Matching a cell to a KG entity: CEA task.
    - Assigning a KG property to the relationship between two columns: CPA
task

The challenge will be run with the support of the AICrowd platform:
https://www.aicrowd.com/organizers/tabular-data-to-knowledge-graph-matching

We encourage participants to submit a system paper. The paper should be no
more than 8 pages long and formatted using the LNCS Style. These papers are
not peer-reviewed, but they will revised by 1-2 challenge organisers.



Support for ontology alignment and link discovery
----------------------

Ontology alignment and link discovery systems are welcome to participate.
We plan to create input data in OWL/RDF format to facilitate their
participation.


Challenge prizes
----------------------

There will be prizes sponsored by SIRIUS (https://sirius-labs.no/) for the
best systems in the challenge.

The prize winners will be announced during the ISWC conference (on October
30, 2019). We will take into account all evaluation rounds specially the
one running till the conference dates.
