“…Topic ontologies are a specific type of ontologies which specify topics as nodes of a directed acyclic graph. An edge in the graph then implies an "is part of"-relation between the topics (Xamena et al, 2017). The effort in creating topic ontologies ranges from ad-hoc decisions (e.g., tags for blog posts) to extensive classification schemes for libraries.…”

Many computational argumentation tasks, like stance classification, are topic-dependent: the effectiveness of approaches to these tasks significantly depends on whether the approaches were trained on arguments from the same topics as those they are tested on. So, which are these topics that researchers train approaches on? This paper contributes the first comprehensive survey of topic coverage, assessing 45 argument corpora. For the assessment, we take the first step towards building an argument topic ontology, consulting three diverse authoritative sources: the World Economic Forum, the Wikipedia list of controversial topics, and Debatepedia. Comparing the topic sets between the authoritative sources and corpora, our analysis shows that the corpora topicswhich are mostly those frequently discussed in public online fora-are covered well by the sources. However, other topics from the sources are less extensively covered by the corpora of today, revealing interesting future directions for corpus construction.

“…Principles of unification are outlined in [17], but only the structure of the KB on facts is given as a base. The paper [18] is characterized by a detailed analysis of ontology, but is mainly a theoretical work without practical implementation. In [19], the complex problem of the knowledge representation methodology is formulated, but specific ways of its practical implementation are not indicated.…”

“…Moreover, the IEDM continues with an extra step that performs an additional ordering on the equations vector (Xamena et al, 2012). Due to this strategy, the number of linear assignment blocks might increase.…”

“…It includes a calculation procedure of the complexity of equations and variables in the system that privileges the generation of blocks of linear equations. Finally, the latest evolution of the DM is the Improved EDM (IEDM) (Xamena et al, 2012). This enhancement on the EDM performs a prior ordering on the equations by their complexity degree.…”
