Onto-SimFCA: A Two-step Mapping Method for Ontologies in MAS

The problem of ontology mapping is tackled in the context of MAS and real life ontologies, context that requires an increased degree of dynamism and the ability to handle high amounts of data. Our solution follows the guidelines of lazy mapping, striving to map only what is necessary and only when it is necessary by using lexical based mapping methods combined with proxy ontologies. However, we are not omitting from this endeavor the accuracy of mapping since our two-layer process has FCA as the second mapping step

Client Provider Collaboration for Service Bundling

The key requirement for a service industry organization to reach competitive advantages through product diversification is the existence of a well defined method for building service bundles. Based on the idea that the quality of a service or its value is given by the difference between expectations and perceptions, we draw the main components of a frame that aims to support the client and the provider agent in an active collaboration meant to co-create service bundles. Following e3-value model, we structure the supporting knowledge around the relation between needs and satisfying services. We deal with different perspectives about quality through an ontological extension of Value Based Argumentation. The dialog between the client and the provider takes the form of a persuasion whose dynamic object is the current best configuration. Our approach for building service packages is a demand driven approach, allowing progressive disclosure of private knowledge

The Argumentative Mediator

In this paper we introduce a negotiation mediator in a multiagent context. When negotiation fails, a mediator can interact with the parties, find out about their goals, ontologies, and arguments for and against negotiation outcome, and suggest solutions based on previous experience. An algorithmic schema to be instantiated with particular argumentation, semantic alignment and case-base reasoning techniques is presented. The proposal is neutral with respect to which particular technique is selected. An example illustrates the approach that is framed in the existing body of literature on argumentation and mediation.This research has been supported by Generalitat de Catalunya project 2014 SGR 118.Peer Reviewe
