Argumentative Approach for the Discovery Truth: The Role of Source Dependence
Dorsaf Salah, Badran Raddaoui, Mohamed Ali Othmani · 2019
In many real-world applications, the information available especially in the Web is often obtained from non original and dependent sources i.e information comes from a variety of dependant sources. So that, obtaining original and dependant sources of information is a challenging task since these sources often provide a large amount of conflicting information. In this paper, we propose a new way to improve the discovery of the truth, taking into account the dependency between the data sources. Intuitively, if two data sources provide a large number of common values and many of these values are rarely provided by other sources (e.g., particular false values), it is very likely that one copies from the other. For that purpose, we develop an argumentative approach based on propositional logic to discover the truth using a dependence measure and a set of principles between sources of information.
