LocWeb2020 at WWW2020

The 10th International Workshop on Location and the Web

LocWeb is happening as an online workshop! We will run the workshop in a slightly different format this year, and the main aim is to still give all authors the option to present their papers and get feedback as well as general discussions. Details of online participation are below.

Please also check with the main conference for online participation and sessions. This is in line with the WWW conference logistics: https://www2020.thewebconf.org/press

21. April 2020
In conjunction with
WWW 2020 The Web Conference
Taipei, Taiwan – Only Online Participation (due to Covid-19)

Closing and Wrap-up

Workshop theme

We are excited to announce that LocWeb2020 has been accepted as a workshop at the WWW2020 conference!

Location and geospatial analytics are important aspects in a wide range of Web research and systems. LocWeb 2020 will continue a successful workshop series at the intersection of location-based analytics and Web architecture. It focuses on Web-scale services and systems facilitating location-aware information access as well as spatial social behavior analytics as part of social computing. The location topic is seen as a cross-cutting issue equally concerning information access, semantics and standards, social analysis and mining, and Web-scale systems and services. It will explore the connection of the Web to the real physical and spatial world. We aim for a highly interactive, collaborative full day workshop with ample room for discussion and demos that will explore and advance the topic, with contributions from research and industry.

New application areas for Web architecture, such as the Internet of Things (IoT) and the Web of Things (WoT), will lead to increasingly rich and large sets of applications for which location is highly relevant as the connection to the physical world. Location has high importance in Web-based designs, and it continues to provide challenging research questions.

It plays important roles in large systems of social and societal importance, and we aim to explore this connection further under the topics of data science for social good and through ways to improve people’s lives.

Call for Papers

LocWeb will solicit submissions under the main theme of Web-scale Location-Aware Information Access and spatial social computing. 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.


The topics are designed to reflect the multitude of fields that demand and utilize location data. We encourage submissions to take an interdisciplinary perspective at the topic of location on the Web.

  • Location-Aware Information Access
  • Spatial Social Behavior
  • Location-Aware Web-Scale Systems and Services
  • Location in the Internet/Web of Things

Submission instructions

We solicit full papers of 6-8 pages, and short papers of up to 4 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, so please provide your name and affiliation.

Submit via easychair: https://easychair.org/conferences/?conf=locweb2020

Submissions should follow the ACM styles and guidelines of the WebConf conference proceedings, using the “sigconf” format. Accepted workshop papers will be published in the WWW companion proceedings and the ACM Digital Library. For inclusion in the proceedings, at least one author of the accepted paper has to register for the workshop and present the paper.

Presenters are encouraged to bring demos to the workshop, to facilitate discussion and make the workshop more interactive.
