User task

Construct structured knowledge for a portal that will access information about research. This knowledge includes information about
  • Research topics
  • Conferences, workshops, seminars, talks
  • Researchers and research groups
  • Roles of researchers (in research groups, on Program and Organization committees, etc.)
  • Publications (in these conferences, as well as journals, books, etc.)
  • Relevant web page URLs (e.g. for papers, conferences, demos, topics)
For starters, capture information about
  • your own research topics
  • your own research group (organization, address, key personnel, such as head of group and active researchers, and their roles, any software tools associated with the group and their types, etc.)
  • your own publications in the past year or two (with links to them, as well as keywords ideally, from the controlled hierarchy that others use as well or topics, etc.)
  • Conferences, workshops, and other events you were involved in.

Sample questions the knowledge base should be able to inform:

  • Give me links to recent publications on topic T from researchers in group X
  • Give a list of all conferences and workshops related to topic T that took place during the past N years, and their locations.
  • Who published in conference C from organization O in year Y, and what roles do they have within their organizations
Use these questions as a guidance, but feel free to expand the knowledge base in any direction. Note that not all the tools will capture all types of information described above.


Each participant of the evaluation can use one or more of the tools to add their data. We encourage participants to use more than one tool to be able to compare different features.
All users of the same tool will have access to the same knowledge base, share the information and develop the knowledge collaboratively.
We encourage participants to edit / change / discuss what others have created.
At the start of the evaluation, the tools will contain some initial data (the same for all tools). Feel free to change it, or discuss it.


  1. User name: Please use the same user name for all the tools so that we can aggregate the information to determine the most active participant. The name does not have to be your real name. The following are the requirements for a user name that will work for all the tools: add requirements
  2. Time frame: The evaluation will run from April 16 through April 30
