Pushing Toulmin Too Far: Learning From an Argument Representation Scheme

Many researchers have proposed representational schemes to capture complex reasoned discourses. In this paper, we use our experiences with argument representation to examine some of the issues affecting the design of these representational schemes. Our discussions focus on how well a particular scheme, Toulmin structures, maps into the domain of argumentative discourse and captures and highligh...

Too Much Information Can Be Too Much for Learning Eciently

In designing learning algorithms it seems quite reasonable to construct them in a way such that all data the algorithm already has obtained are correctly and completely re ected in the description the algorithm outputs on these data. However, this approach may totally fail, i.e., it may lead to the unsolvability of the learning problem, or it may exclude any e cient solution of it. In particula...

Wheeler Graphs: Variations on a Theme by Burrows and Wheeler

The famous Burrows-Wheeler Transform was originally defined for single strings but variations have been developed for sets of strings, labelled trees, de Bruijn graphs, alignments, etc. In this talk we propose a unifying view that includes many of these variations and that we hope will simplify the search for more. Somewhat surprisingly we get our unifying view by considering the Nondeterminist...
