Workshop on Geo-Knowledge Graphs (GKG17)
at COSIT 2017; 13th International Conference on Spatial Information Theory L’Aquila, Italy, September 4-8 2017.
Workshop Description and Scope
Knowledge graphs, i.e., making semantically annotated and interlinked raw data available on the Web, has taken information technologies by storm. Today such knowledge graphs power search engines, intelligent personal assistants, and cyber-infrastructures. For instance, the publicly available part of the Semantic Web-based Linked Data cloud contains more than 150 billion triples distributed over 10000 datasets and connected to another by millions of links. Geographic data play a significant role in this cloud and knowledge graphs in general as places function as central nexuses that connect people, events, and physical objects. Consequently, geo-data sources are among the most central and densely interlinked hubs. Beyond their sheer size, the diversity of these data and their inter-linkage are of major value as they enable a more holistic perspective on complex scientific and social questions that cannot be answered from a single domain's perspective. Hence, knowledge graphs such as those implemented using the Linked Data paradigm bear potential to address many fundamental challenges of geoinformatics.
In this workshop we will discuss various aspects of geo-knowledge graphs ranging from their extraction and construction from unstructured or semi-structured data, issues of data fusion, conflation, and summarization, geo-ontologies, to query paradigms and user interfaces. By focusing explicitly on geo-knowledge graphs in general, we aim at broadening the focus beyond the Semantic Web technology stack and thus also beyond RDF-based Linked Data.
Topics of interest include (but are not limited to):
- Extracting geo-knowledge graphs from unstructured/semi-structured data
- Summarization techniques for geo-knowledge graphs
- Materializing versus computing statements, e.g., triples
- APIs for geo-knowledge graphs
- Geo-ontologies and vocabularies
- Geographical Linked Data
- Research, benchmarking, and use case reports about GeoSPARQL and related query languages and data stores, e.g., triple stores
- Visualization of geo-knowledge graphs and visual query interfaces
- Provenance, trust, and credibility as they relate to geo-knowledge graphs
- Enrichment and cleaning of geo-knowledge graphs and alignment to existing graphs
- Constraints and spatiotemporal scoping of geo-knowledge graphs
- Integration of geo-knowledge graphs with Geographic Information Systems
- Semantic query expansion
- Exploratory query paradigms
- Semantiocs-based geo-data compression
- Measures of relatedness, similarity, and analogy
- Place name disambiguation
- Co-reference resolution
- Integration of sensor-based observations into knowledge graphs
- Geo-knowledge graph and gazetteers
- Qualitative reasoning based on geo-knowledge graphs
- Cognitive aspects of geo-knowledge graphs
The workshop will focus on intensive discussions on the topic of geo-knowledge graphs and more specifically on defining an agenda for future research. The workshop will accept two kinds of contributions, full research papers (7-8 pages) presenting new work, surveys, and major findings in the areas indicated above, as well as statements of interest (5-6 pages). While full papers will be selected based on the review results adhering to classical scientific quality criteria, the statements of interest should raise questions, present visions, and point to existing gaps. However, statements of interest will also be reviewed to ensure quality and clarity of the presented ideas. The presentation time per speaker will be restricted to 10 minutes for statements of interest and 15-20 minutes for full papers. This ensures that there is enough time for discussions, interactions, and breakout group leading to a typical workshop setting instead of a mini-conference. Papers should be formatted according to the Latex or Doc LNCS template. Papers will be published via CEUR-WS.
Submissions shall be made through easychair at GKG17 .
To register for the workshop, please visit http://www.cosit2017.org.
All presented papers will be made available through the workshop webpage as well as via CEUR-WS (to ensure that the copyright remains with the authors). Full papers should be approximately 7-8 pages, while statements of interest should be between 5-6 pages. We will organize an open-call special journal issue if there is sufficient interest and quality in terms of the submissions. A potential journal for such a special issue would be the Semantic Web journal by IOS Press.
