This paper takes a "bottom-up" perspective by assessing the contribution made by linguistic signals (connectives), using insights from the relevant literature as well as verification by practical text annotation. We work primarily with the German language here and focus on the realm of contrast. Thus, we suggest a new inventory of contrastive connective functions and discuss their relationship to contrastive coherence relations that have been proposed in earlier work.}, language = {en} } @misc{SaintDizierStede2017, author = {Saint-Dizier, Patrick and Stede, Manfred}, title = {Foundations of the language of argumentation}, series = {Argument \& computation}, volume = {8}, journal = {Argument \& computation}, number = {2 Special issue}, publisher = {IOS Press}, address = {Amsterdam}, issn = {1946-2166}, doi = {10.3233/AAC-170018}, pages = {91 -- 93}, year = {2017}, language = {en} } @misc{AfantenosPeldszusStede2018, author = {Afantenos, Stergos and Peldszus, Andreas and Stede, Manfred}, title = {Comparing decoding mechanisms for parsing argumentative structures}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {1062}, issn = {1866-8372}, doi = {10.25932/publishup-47052}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-470527}, pages = {18}, year = {2018}, abstract = {Parsing of argumentative structures has become a very active line of research in recent years. Like discourse parsing or any other natural language task that requires prediction of linguistic structures, most approaches choose to learn a local model and then perform global decoding over the local probability distributions, often imposing constraints that are specific to the task at hand. Specifically for argumentation parsing, two decoding approaches have been recently proposed: Minimum Spanning Trees (MST) and Integer Linear Programming (ILP), following similar trends in discourse parsing. In contrast to discourse parsing though, where trees are not always used as underlying annotation schemes, argumentation structures so far have always been represented with trees.
