Subject: Non-hierarchical concept ontologies Dear All, for the next development phase of our text annotation and analysis tool CATMA (https://catma.de) we'd like to find out more about the theory, the epistemic benefits and the computational approaches toward what we have tentatively called "non-hierarchical concept ontologies". Here's why: In CATMA (as in many other annotation tools that implement markup schemata) a concept ontology takes on the form of a tagset, which - in the UI as well as conceptually - is presented to the user as a tree data-structure. One of CATMA's core features, however, is the ability to extend and modify tagsets 'on the fly' while annotating documents, something which our users tend to do quite regularly. And sooner or later they then come up with the idea that they would want to re-order tags and sub-tags across established parent-child-dependencies. This is where things become interesting not just pragmatically (we use a graph data base, so dependencies could in principle be re-calculated and re-mapped), but more so conceptually. In this perspective the question is not just whether one can fix and/or extend an existing structure/ontology - the question is whether one can productively THINK a non-hierarchical concept ontology and clearly identify its heuristic added value. What exactly is the added value of a 'fact-turned-category' derived from a triple-store query, and what are its limits? Against this backdrop I'd like to ask whether HUMANIST readers could point me to philosophical as well as CS approaches - literature, projects, etc. - that reflect on the philosophical as well as the computational affordances and constraints of concept ontologies that might be anything but hierarchically ordered: e.g. networked, distributional, probabilistic, etc. Many thanks, Chris -------------------------------- Dr. Jan Christoph Meister Universitätsprofessor für Digital Humanities Schwerpunkt Deutsche Literatur und Textanalyse Institut für Germanistik Universität Hamburg Überseering 35 22 297 Hamburg +49 40 42838 2972 +49 172 40865 41 http://jcmeister.de _______________________________________________ Unsubscribe at: http://dhhumanist.org/Restricted List posts to: email@example.com List info and archives at at: http://dhhumanist.org Listmember interface at: http://dhhumanist.org/Restricted/ Subscribe at: http://dhhumanist.org/membership_form.php
