Overview

Please occasionally check back for updates and announcements.

This full-day workshop on September 10, 2019 at COSIT 2019 is meant to attract participants with a research interest in place-based search. This workshop will advance discussion on two main topics: the current theoretical and technical limitations of place-based search and the limitations that can be addressed in the next few years. The morning session will focus on participant presentations and cataloging current limitations of place-based search through a hands-on activity. The afternoon session will be dedicated to general and breakout group discussion on if and how individual limitations can be addressed in the future. Those interested should submit a 2-3 page paper on current research on, or a position on future directions of place-based search. Please see details below.

 

Topic

Currently, many search tools allow users to tailor results to a locality by specifying a place name or exploring a map. But how exactly do these tools interpret a place name, and do these interpretations capture an adequate representation of places? How valuable are these tools in their present form for place-based search? This workshop will investigate these questions and advance discussion on two topics: the current theoretical and technical limitations of place-based search and the limitations that can be addressed in the next few years. Place is a much discussed topic in the spatial information theory community, so emphasis at this workshop will be on how search tools in particular can, should, and do handle place references.

Place-based search plateaued with the maturation of web mapping and location- based services and has since remained relatively undeveloped. In most text-based search tools, place names are handled, at best, as links to some geometric footprint stored in a gazetteer, which can then be used to query nearby, contained, or overlapping results. Other aspects of place, such as their enabling of events, people’s sense of place, and even variable interpretations of where places are remain outside current capacities of place-based search tools.

Relevant work on place-based search can be found in contexts such as Digital Earths (e.g., Gore 1998), Digital Libraries (e.g., Lafia et al. 2016), Qualitative Spatial Reasoning, and Geographic Information Retrieval (GIR, e.g., the SPIRIT project (Jones et al. 2002)). However, place-based search is more specific than GIR, focusing on how place name interpretations influence search results. Many search tools in these and other contexts provide some form of geobrowsing, i.e., map-based search.

How to Prepare

We ask that participants submit a 2-3 page paper on either current research or a position on future directions of place-based search, which will be used to select attendees. Example topics may include fuzzy or local gazetteers, non-geometric place representations, place-based querying and ranking, linguistic and contextual approaches, and evaluation methods for place-based search. All submissions must discuss how at least one search tool studied interprets and/or represents place.

Submissions will be reviewed by the organizers for topical fit and innovativeness. If accepted
papers contain enough novel material and the discussions suggest further development after
the workshop, a call for full papers to a special journal issue will follow.

Please submit manuscripts using the button above or the submission link on the workshop’s EasyChair page: https://easychair.org/cfp/COSIT_BPN_2019.

Program

(tentative)

The first session (morning session) of this full-day workshop will discuss positions on what place-based search is, focusing on its current theoretical and practical limitations. The second session (afternoon session) will take the form of a group-based discussion to identify how limitations can be addressed in the near term.

 

Session I (900 – 1230)

  • Motivating presentation: Organizer of invited speaker (20′)
  • Introductory questionnaire for participants (15′)
    • Aimed to establish common ground on what place-based search means. Sample questions will include:
      • What are examples of content that should be searchable by place?
      • How does place-based search differ from location-based / location-inclusive search (LBS) and GIR more generally?
      • Should search functionality change when searching for georeferenced data versus non-georeferenced data?
  • Questionnaire results discussion (30′)
  • Participant paper presentations (5′ + 3′ Q/A)
    • Participants will be asked to highlight which technical capabilities from the questionnaire exercise their work addresses, or new ones to be added.

Coffee Break (1030 – 1100)

  • Participant paper presentations (continued)

Lunch break (1230 – 1400)

Session II (1400 – 1700)

  • General discussion: Limitations of place-based search (30′)
    • Participants will catalog issues discussed during Session I, and, for each of them, whether it is known how to solve it or not.
  • Breakout group discussion (60′)
    • Participants will self-organize into groups around a single limitation and discuss possible steps to address it.

Coffee Break (1530 – 1600)

  • Plenary discussion (60′)
    • Participants will reconvene to discuss findings and potential publication outlets for the results.

 

Post Workshop Event (1830)

  • Walk or ride bus to Old Town for an icebreaker and beer tasting. Note: Leave campus by 1745
