(Extended Deadline – May 24th)

27th International Symposium on Temporal Representation and Reasoning Bozen-Bolzano (Italy), 23rd-25th September 2020

Co-Located with the Bolzano Summer of Knowledge 2020

Aims and Scope

Since 1994, the TIME International Symposium on Temporal Representation and Reasoning aims to bring together researchers in the area of temporal reasoning in Computer Science. TIME 2020 encompasses three tracks, but has a single program committee. The conference will be organized as a combination of technical paper presentations, keynote talks, and tutorials.

Invited Speakers

Clare Dixon (University of Liverpool, UK)
Pedro Cabalar (University of Corunna, Spain)
Johann Eder (Alpen-Adria Universität Klagenfurt, Austria)

Following a long-standing tradition, submission topics include (but are no limited to):

  • Temporal aspects of agent- and policy-based systems
  • Spatial and temporal reasoning
  • Time in natural language processing
  • Spatio-temporal knowledge representation systems
  • Reasoning about actions and change
  • Planning and planning languages
  • Ontologies of time and space-time
  • Belief and uncertainty in temporal knowledge
  • Temporal learning and discovery
  • Temporal data models and query languages
  • Temporal query processing and indexing
  • Temporal data mining
  • Time series data management
  • Stream data management
  • Spatio-temporal data management, including moving objects
  • Data currency and expiration
  • Indeterminate and imprecise temporal data
  • Temporal constraints
  • Specification and verification of systems
  • Verification of web applications
  • Synthesis and execution
  • Model checking algorithms and implementations
  • Verification of infinite-state systems
  • Reasoning about transition systems
  • Other aspects of temporal architectures

Submission & Publication

TIME 2020 accepts submissions in PDF format, no longer than 12 pages excluding references and appendix. The appendix is limited to 5 pages, and the reviewers may or may not take it into account for their recommendation. Submissions must be formatted following the LIPIcs instructions (https://submission.dagstuhl.de/documentation/authors), and preferably redacted in LaTex.

Submissions are managed by EasyChair:


Paper abstracts must be submitted one week before the final paper submission deadline.

TIME policy is single blind, so the names of the authors should not be hidden in the submitted draft. Members of the program committee, excluding the co-chairs, are allowed to submit papers. Submitted papers will be refereed for quality, correctness, originality, and relevance to the conference.

Submissions to TIME 2020 must be original, and parallel submissions of the same material to other conferences or journals are not allowed. Accepted papers will be presented at the symposium and included in the proceedings, which will be published by LIPIcs-Leibniz International Proceedings in Informatics (https://www.dagstuhl.de/en/publications/lipics/). This is a series of high-quality peer-reviewed conference proceedings, and published according to the principle of OpenAccess. At least one author of each accepted paper must register at the conference and present either virtually or (if possible) in person. In person participation in the symposium will not be a prerequisite for publication.

Authors of selected papers will be invited to submit an extended version of their contribution to a special issue of a high quality journal yet to be decided.
