Note: Although the name was inspired by that of the late OntoWeb Thematic Network, OntoWeb-Cz was not formally linked to this network project.



  • Overview
  • Research links
  • Events


    The OntoWeb-Cz page is conceived as an informal hub for national-level reserch in three closely related areas:

    Although its main purpose is to improve mutual awareness among the Czech researchers themselves, I hope it will also be of some use for foreign researchers in the above areas, who seek scientific partners or just wonder whom to meet while visiting the Czech Republic. If you wish to receive information on forthcoming events or significant updates of this page, please, let me know.

    The following "definitions" are very simplified and subjective; their role is to clarify the relations among the three areas.

    For start-up links on applied ontology see e.g. the Laboratory for Applied Ontology.

    For start-up links on semantic web see e.g. the Semantic Web Community Portal or the Semantic Web Activity page at W3C.

    For start-up links on web information extraction see e.g. the Web IR & IE page.

    The following table lists the key organisations, groups, projects and contact persons. It will hopefully grow.

    Note that the contact is often just the person most deeply acquainted with the topics (and thus most likely to respond) rather than an official group/project leader. The research is frequently connected with newly commenced (PhD) projects rather than with mature research.

    In this section, I try to list forthcoming and recent events related to the topic areas, in the Czech Republic. If you know of any other, please, let me know.

    Beside irregular events listed below, note a high number of regular seminars that occasionally touch the topic areas. You can have a look at the list maintained on the page of the KEG seminar (bottom part). Although the list itself is in Czech, many of the seminars have a page in English.
