Dear all,

similar to last year, we will be organizing a workshop that I hope is of 
interest to some of you.


Call for Papers: 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 

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.

*Workshop Topics*

-    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 

-   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

*Workshop Format*

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 

To register for the workshop, please visit http://www.cosit2017.org.

*Workshop Proceedings*

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.

*Important Dates*

     Submission due: 22 May 2017
     Acceptance Notification: 19 June 2017
     Camera-ready Copies: 28 June 2017
