***************************************************************

KGCW is a full-day workshop on Knowledge Graph construction co-located with the Extended Semantic Web Conference 2021 (ESWC2021) <https://2021.eswc-conferences.org/>. KGCW has a special focus this time on knowledge graph construction methods that involve or analyze the roles of users. Our goal is to provide a venue for scientific discourse, systematic analysis, and rigorous evaluation of languages, techniques, and tools, as well as practical and applied experiences and lessons-learned for constructing knowledge graphs from academia and industry. The workshop complements and aligns with the activities of the W3C CG on KG construction <https://www.w3.org/community/kg-construct/>.

Topics of interest
-------------------------
Mapping based Knowledge Graph Construction
Mapping languages for constructing Knowledge Graph from legacy datasets
End-User Interfaces (UI) for (collaborative) editing and viewing for Knowledge Graphs building rules and management platforms in general
Approaches and techniques on 
(semi)automatically generate mappings
collaborative mappings generation
exploiting mappings for query answering
Tools for Knowledge Graph Construction
Architectures for Knowledge Graph construction systems
(Sustainable) workflows for Knowledge Graph construction & publishing
Methods and Techniques for Knowledge Graph Construction
Seamless (distributed) integration/interlinking from heterogeneous data sources
Dynamic discovery and retrieval of data for KG construction
Quality, Provenance, privacy and trustworthiness of Linked Data construction
Knowledge Graph construction and publishing of streaming data at run-time
Benchmarks for Knowledge Graphs construction and publishing
Lessons learnt, In Use and Experience
Experience, lessons learnt, and best practices for generating and publishing
Negative results and in-use/applied descriptions

Mapping Challenges
-----------------------------
Different mapping languages for heterogeneous data emerge, such as RML, SPARQL-Generate, or ShExML. In most cases, the proposed mapping languages rely on existing but repurposed specifications, such as R2RML, SPARQL, or ShEx respectively, complemented by existing specifications for different data formats, e.g., SQL, XPath, JSONPath, etc. While this approach has its merits, there are still some open challenges that affect at least RML but most other mapping languages as well. We identified those challenges as they were mentioned in different repositories and occasions and we compiled a list of open challenges to be addressed: https://kg-construct.github.io/workshop/2021/challenges.html <https://kg-construct.github.io/workshop/2021/challenges.html>. We invite people from both industry and academia to come up with their own solutions to these open challenges. 

Submission guidelines
---------------------------------
Share your contribution before the deadline through the OpenReview platform <https://openreview.net/group?id=eswc-conferences.org/ESWC/2021/Workshop/KGCW>.
