Context and motivation[edit]

In a number of application fields, pieces of data and information need to be modelled and visualised so as to analyse patterns of change over time, or so as to pinpoint time-related causal chains. Briefly said, understanding facts often implies understanding processes that lead to facts, or that derive from facts – and reasoning on processes implies mastering the time parameter. However, coping with dirty time-oriented data (inaccurate, incomplete, erroneous, contradictory, etc.) remains, by and large, an open issue. If scientists and practitioners are to foster the emergence of effective solutions, it is of great importance they get an opportunity to confront their approaches, ideas, experiences and methods. The workshop’s ambition is to foster interdisciplinary scientific exchanges both on theoretical or technological aspects and on practical cases/feedbacks stemming from a wide range of application fields.

Topics of interest[edit]

Handling “dirty” time-oriented data is naturally a key issue in human sciences, yet the issue is more generally raised in all activities where unreliable and/or incomplete and/or inaccurate temporal data sets have to be dealt with. The workshop wishes to host contributions covering a wide range of application fields, of scientific practices, and of theoretical or methodological approaches (historical sciences, environmental sciences, geosciences, conceptual modelling, health sciences, monitoring and planning activities, etc.). Accordingly, we welcome submissions related to (but not limited to) the handling of imperfect time-stamped information sets in the following research areas:

Knowledge Representation, Visual Analytics & Information Visualisation

  • Temporal knowledge discovery, databases.
  • Temporal logic, temporal representation and reasoning.
  • Uncertainty modelling, data and information quality.
  • Information visualisation, visual representations and interaction techniques.
  • Visualisation of temporal or spatio-temporal data.
  • Process and workflow visualisation.


  • Geovisualisation, geovisual analytics.
  • Simulation, multi-agent systems.
  • Geography, geomatics, time geography, mobility, flows, etc.
  • Urban planning, landscape analysis & monitoring, etc.
  • Risk assessment, climate research.

Historical Sciences, Health Sciences, Social Sciences

  • Archaeology, environmental archaeology, paleoethnobotany.
  • Ethnology, ethnography, linguistics, etc.
  • History, history of art and architecture, etc.
  • ITC in health services.
  • Intelligence, social networks, etc.
  • Business intelligence.


  • Submission deadline: April 27, 2014
  • Notifications: May 16, 2014
  • Camera-ready version: June 5, 2014
  • Workshop 16-17 September 2014

Submissions are invited on the above topics, either as short papers (4 pages) - position papers, test cases - or as regular contributions (8 pages). Submissions will be reviewed by the workshop's Programme Committee in an interdisciplinary approach (cross-examination from the application field point of view and from a KR perspective). All selected papers will be published in the workshop notes, either in conjunction with the conference proceedings or online as part of an Open Access peer-reviewed journal. Submissions will be handled electronically, formatting guidelines and address to be announced shortly here:

Event format and expected outcomes[edit]

The event will combine a “traditional” workshop format - keynotes focusing on dirty time-oriented data as such and talks focusing either on theoretical or technological aspects or on feedbacks from a variety of application fields - and a collective initiative aimed at pulling together test cases and resources (interdisciplinary references on one hand, and on the other hand test benches freely usable by the community in its subsequent work). Expected outcomes of this workshop accordingly include a better acquaintance with relevant work across scientific domains and application fields as well as the emergence of ad-hoc metrics – an attempt to ease the task of cross-examining responses to data quality issues. Ultimately, the initiative wishes to contribute to the strengthening of the community of analysts dealing with quality issues in the context of temporal data and information sets.
