Collaborative Computer-Supported Argument Visualization (CCSAV) has often been proposed as an alternative over more conventional, mainstream platforms for online discussion (e.g., online forums and wikis). CCSAV tools require users to contribute to the creation of a joint artifact (argument map) instead of contributing to a conversation. In this paper we assess empirically the effects of this f...

Argument visualisation (AV) tools enable structured debates around issues, positions and arguments. These tools have the potential to substantially improve transparency e.g. by enabling understanding complex legislation and debating. In this paper we present the results of the evaluation of an AV platform by experts and policy makers. The results suggest the potential of such tools is large par...

Induced by “big data,” “topic modeling” has become an attractive alternative to mapping cowords in terms of co-occurrences and co-absences using network techniques. Does topic modeling provide an alternative for co-word mapping in research practices using moderately sized document collections? We return to the word/document matrix using first a single text with a strong argument (“The Leiden Ma...

This research advocates the idea of combining argumentation theory with the social web technology, aiming to enact large scale or mass argumentation. The proposed framework allows mass-collaborative editing of structured arguments in the style of semantic wikipedia. The long term goal is to apply the abstract machinery of argumentation theory to more practical applications based on human genera...

Argumentation is central to law. Written and oral argument structures, however, are often difficult to analyze and employ in instruction. Diagrammatic models of argument offer a potential solution to these problems. In this paper we report on the results of an empirical study into the diagnostic utility of argument diagrams in a legal writing context. The focus is on comparing experts’ and stud...

The Luck Argument is among the most influential objections to the main brand of libertarianism about metaphysical freedom and moral responsibility. In his work, Alfred Mele [2006. Free will and luck. Oxford: Oxford University Press] develops – and then attempts to defeat – the literature’s most promising version of the Luck Argument. After explaining Mele’s version of the Luck Argument, I prese...

The issue of adjuncts has long been a neglected field of linguistic study whether it be syntactic or semantic. It is only in Pustejovsky (1995) that we find a brief mention of adjuncts. In addition to what the author calls true arguments, default arguments, and shadow arguments, he sets up a class of true adjuncts citing the following sentence , Mary drove down to New York on Tuesday. We will t...

Virtue theories have become influential in ethics and epistemology. This paper argues for a similar approach to argumentation. Several potential obstacles to virtue theories in general, and to this new application in particular, are considered and rejected. A first attempt is made at a survey of argumentational virtues, and finally it is argued that the dialectical nature of argumentation makes...

This paper describes research that aims to develop an argument visualization tool and associated method for supporting eParticipation and online deliberation. Based on the state-of-theart in the field of computer-supported argument visualization, the tool will support the work of relevant eParticipation actors by enabling them to navigate through arguments contained in relevant consultation and...

This paper deals with the problem of the projection of arguments, i.e., how the arguments of a predicate are integrated into a syntactic structure. My starting point is the model offered in Borer (1993). This model is defined by Borer as a 'syntactic predicate based account' of the projection of arguments. In the next section I will briefly sketch the different approaches to the problem of argu...
