Location has quickly moved into the mainstream of the (mobile) Web. It also continues to be a strong driver of applications and research activities. 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 location-based services, involving more powerful mechanisms in terms of information retrieval, mining, analytics and semantics. New application areas for Web architecture, such as the Internet of Things (IoT) and the Web of Things (WoT), also mean that there will be increasingly rich and large sets of resources for which location is highly relevant.

Following the successful LocWeb workshops in 2008, 2009, 2010, 2014, 2015, and 2016, LocWeb 2017 continues the workshop series, addressing issues 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.

LocWeb is an integrated venue where the location aspect is discussed in depth within an interdisciplinary community. It is also highly interactive and collaborative, with ample room for discussion and demos that will explore and advance the geospatial topic in its various relevant areas. We expect the workshop to further the integration of the geospatial dimension into the Web, and promote challenging research questions.

LocWeb solicits submissions under the main theme of Web-scale Location-Aware Information Access. Subtopics include (i) geospatial semantics, systems, and standards; (ii) large-scale geospatial and geo-social ecosystems; (iii) mobility; (iv) location in the Web of Things; and (v) mining and searching geospatial data on the Web. The workshop encourages work describing Web-mediated or Web-scale approaches that build on reliable foundations, and that thoroughly understand and embrace the geospatial dimension.
