Strength in coalitions: Community detection through argument similarity

Argument & Computation

Based on their stance, we identify argumentative coalitions to define them; then, we apply a similarity-based evaluation method over the set of arguments in the coalition to determine the level of cohesion inherent to each community, classifying them appropriately. Introducing conflict points and attacks between coalitions based on argumentative (dis)similarities to model the interaction between communities leads to considering a meta-argumentation framework where the set of coalitions plays the role of the set of arguments and where the attack relation between the coalitions is assigned a particular strength which is inherited from the arguments belonging to the coalition. Various semantics are introduced to consider attacks’ strength to particularize the effect of the new perspective....

Similarity notions in bipolar abstract argumentation

In this work, we study similarity as a tool useful to improve the representation of arguments, the interpretation of the relations between arguments, and the semantic evaluation associated with the arguments in the argumentative process. In this direction, we present a novel mechanism to determine the similarity between two arguments based on descriptors representing particular aspects associated with these arguments. This mechanism involves a comparison process influenced by the context in which the process develops, where this context provides the relevant aspects that need to be analyzed in the application domain. Then, we use this similarity measure as a quantity to compute the result of attacks and supports in the argumentation process. These valuations, applied to a Bipolar Argumentation Frameworks, allowed us to refine the argument relations, providing the tools to establish a family of new argumentation semantics that considers the similarity between arguments as a crucial part for the argumentation process.

A semiformal way to express these patterns of reasoning were proposed by Walton, through argument schemes from analogy. From this, it is possible to propose computable approximations for comparing arguments. In this paper we introduce a formalism based on the comparison of arguments through descriptors or labels which describes an aspect that the argument refers to. This formalism allows us classifying similar arguments considering the natural descriptors of them, in a specific context.

After presenting the theoretical background that supports the proposed solutions, the complex problem of the development of AR multi-platform mobile applications is introduced. The problem about how to choose a framework for developing multi-platform applications is described, and a general model for developing mobile applications with AR is proposed. The advances were applied to the field of m-learning. A linear algebra educational practice was designed using MADE-mlearn, and an augmented reality mobile app called AlgeRA was developed using MobileRA methodology. The instantiation of the general model for the development of AlgeRA is reported. It includes the development environment, the programming libraries (to manage 3D objects repositories, patterns r...

An argumentation scheme is a representational tool for modeling common patterns of reasoning; in particular, it displays the form of an argument by showing how the argument is built using the inferential structures commonly used in everyday discourse. Argument schemes are very useful in contexts such as legal argumentation, scientific argumentation, and especially in Artificial Intelligence applications. One type of argumentation scheme corresponds to appeal to Expert Opinion or Position-to-Know argumentation. Position-to-know reasoning is typically used in an information seeking type of dialogue where one has to depend on a source. Most of such argumentation frameworks are based on Dung's seminal work characterizing Abstract Argumentation Frameworks. In this work, we introduce a novel framework, called Expert Argumentation Framework (EAF), extending AF with the capability of modeling the quality of expert associated with the arguments that were proposed. Resumen La argumentación es una forma de razonamiento que se relaciona profundamente con el mecanismo humano de razonamiento basado en el sentido común. Un esquema de argumentación es una herramienta de representación para modelar patrones comunes de razonamiento. En particular, estos esquemas muestran la forma de un argumento, es decir, cómo se construye el argumento utilizando estructuras inferenciales comúnmente utilizadas en el discurso cotidiano. Los esquemas de argumentación son muy utilizados en contextos como la argumentación legal, argumentación científica y, especialmente, en aplicaciones de Inteligencia Artificial. Un tipo de esquema de argumentación es aquel que apela a la Opinión Experta o Posición de Conocer. El razonamiento basado en la Posición de Conocer es típicamente utilizado en aquellos diálogos de búsqueda de información donde se depende de una fuente calificada. La mayoría de los marcos de argumentación se basan en el trabajo seminal de Dung que caracteriza un Marco de Argumentación Abstracto (MA). En este trabajo, introduciremos un nuevo marco, llamado Marco de Argumentación Experta (MAE), extendiendo el MA con la capacidad de modelar la calidad del experto asociada con los argumentos queéste propone.

One form of representing arguments is called Argumentation Schemes, in which are argument forms that represent inferential structures of arguments used in everyday discourse, and in special contexts like legal argumentation, scientific argumentation, and especially in AI. One type of argumentation scheme corresponds to appeal to Expert Opinion or Position-to-Know argumentation. Position-to-know reasoning is typically used in an information seeking type of dialogue where one has to depend on a source.

In general, argumentation can be associated with the interaction of reasons in favour and against certain conclusions, so as to determine what conclusions are acceptable. A way of arguing in which the way in which the arguments are constructed, is Defeasible Logic Programming (DeLP); this is a formalism that combines logic programming and defeasible argumentation. This work focuses on the strengthening of the reasoning process, identifying partial connections or determinations between knowledge pieces. Through these relations, it is possible to increase the justifications and foundations that support a particular recommendation, by an analogy process.
