Call for Papers

Location has quickly moved into the mainstream of the (mobile) Web and it continues to be a strong driver of research activities, addressing a wide range of Web-related topics, including search, retrieval, mining, extraction, analytics, mobility, services, and systems. After the initial boost and consolidation of approaches based on the simple use of geospatial coordinates, we now see an increasing demand for more sophisticated systems, stronger retrieval, mining, and analytics solutions, and more powerful semantics. Location is playing a key role as a context factor for users, but also as the implicit or explicit place of resources and people. It also is an important factor in mobile and geo-social applications and is driving geospatially-aware Web data mining.

Following the successful LocWeb workshops in 2008, 2009, 2010, and 2014, LocWeb 2015 will continue this workshop series at the intersection of location-based services and Web architecture. Its focus lies in Web-scale systems and services facilitating location-aware information access. The location topic is understood as a cross-cutting issue equally concerning Web information retrieval, semantics and standards, and Web-scale systems and services.

The workshop is expected to establish a common, integrated venue where the location aspect can be discussed in depth within an interested community. We aim for a highly interactive, collaborative full day workshop with ample room for discussion and demos that will explore and advance the geospatial topic in its various relevant areas. New application areas for Web architecture, such as the Internet of Things (IoT) and the Web of Things (WoT) mean that there will be increasingly rich and large sets of resources for which location is highly relevant. We expect the workshop to further the integration of the geospatial dimension into the Web and promote challenging research questions.

LocWeb solicits submission under the main theme of Web-scale Location-Aware Information Access. Subtopics include geospatial semantics, systems, and standards; large-scale geospatial and geo-social ecosystems; mobility; location in the Web of Things; and mining and searching geospatial data on the Web. The workshop encourages interdisciplinary perspectives and work describing Web-mediated or Web-scale approaches that build on reliable foundations, and that thoroughly understand and embrace the geospatial dimension. We are also interested in work tying into ongoing W3C activities such as Web of Things, Social Web, Data Activity, and Geolocation WG.

Submission Instructions

We solicit full papers of up to 6 pages and short papers of up to 3 pages describing work-in-progress or early results. Authors are invited to submit original, unpublished research that is not being considered for publication in any other forum.

Workshop submissions will be evaluated based on the quality of the work, originality, match to the workshop themes, technical merit, and their potential to inspire interesting discussions. The review process is single blind.

Manuscripts should be formatted using the ACM camera-ready templates ( and submitted in PDF format to Easychair:

Accepted workshop papers will be published in the WWW companion proceedings and available from the ACM Digital Library. This may be regarded as prior publications by other conferences or journals.

For inclusion in the proceedings, at least one author of the accepted paper has to register for the conference. At the time of submission of the final camera-ready copy, authors will have to indicate the already registered person for that publication.

Presenters are encouraged to bring demos to the workshop to facilitate discussion.
