First Joint International Workshop on Semantic Sensor Networks and Terra Cognita

The wide availability of technologies such as GPS, map services and social networks, has resulted in the proliferation of geospatial data on the Web. Similarly, the amount of geospatial data extracted from the Web and published as Linked Data is increasing. Together with large volumes of machine-generated data from sensor networks and the emerging internet of things, these continually growing data have given rise to a number of innovative services and applications.

This workshop aims to provide an inter-disciplinary forum to explore and promote the technologies related to a combination of semantic web, geospatial web and sensor networking. Specifically, to develop an understanding of the ways semantic web technologies can contribute to the growth, integration and deployment of geospatial applications. As a joint workshop, it will explore both foundational technologies of the Semantic Geospatial Web and applications of semantic technologies to large-scale sensor networks and the emerging web of things. The workshop will bring together researchers and practitioners from various disciplines, as well as interested parties from industry and government, to advance the frontiers of these emerging research areas. This field continues to gain popularity, resulting in a need for a forum to discuss relevant issues.


Topics of interest include, but are not limited to:

  • Data models and languages for the Geospatial Web
  • Systems and architectures for the Geospatial Web
  • Geographic information retrieval
  • Linked geospatial data
  • Ontologies and rules in the Geospatial Web
  • Uncertainty in the Geospatial Web
  • User interface technologies for the Geospatial Web
  • Geospatial Web and mobile data management
  • Security and privacy issues in the Geospatial Web
  • Geospatial Web applications
  • User-generated geospatial content
  • Open geospatial data
  • Big geospatial data
  • OGC and W3C technologies and standards in the Geospatial Web
  • Semantic support for Sensor Web Enablement
  • Semantic discovery of sensors, sensor data and services
  • Semantic integration in heterogeneous sensor networks
  • Citizen sensors, participatory sensing and social sensing
  • Semantic web services architectures for sensor networks
  • Semantic algorithms for data fusion and situation awareness
  • Rule-based sensor systems
  • Semantic feedback and control
  • Semantic policy management in shared networks
  • Semantic approaches to status monitoring and configuration of sensor systems
  • Semantic sensor context management and provenance
  • Spatio-temporal reasoning in sensor networks
  • Semantic web in sensor data mashups
  • Integration of semantic sensor networks with Internet/Web of Things
  • Sensors and observations for symbol grounding
  • Scalability, security, trust and privacy in semantic sensor networks
  • Emergent semantics and ambient intelligence in sensor systems
  • Ontologies for sensor and RFID networks
  • Reasoning with incomplete or uncertain information in sensor networks
  • Semantic middleware for active and passive sensor networks
  • Experience in sensor network applications of semantic technologies
  • Semantic reasoning for network topology management


We invite two kinds of submissions:

  • Research papers. These should not exceed 12 pages in length.
  • Demos. Deployed technologies are important if the Geospatial Web is to be realized. We therefore strongly encourage the submission of demos, and the presentation of demos related to research papers (a separate demo paper does not need to be submitted in this case, but the research paper should clearly discuss the demo to be presented). Demo papers should not exceed 5 pages in length.

Submissions should be formatted according to the Lecture Notes in Compute Science guidelines for proceedings available at

Papers should be submitted in PDF format using the Easy chair system:

At least one author of each accepted paper or demo must register for the workshop. Information about registration can be found on the ISWC 2015 Web page:

PLEASE NOTE: ISWC does not allow workshop-only registrations. To attend, you will need to register and pay for the workshop plus the conference. Last time, the workshop proceedings were published electronically in the CEUR series. We plan to do the same this year.
