The success of the Case Based Reasoning (CBR) system depends on the quality of the case data. This quality is dedicated to the study of the case base competence which is measured by the range of problems that can be satisfactorily solved. In fact, modeling case-base competence is a clamorous issue in the discipline of CBR. However, the existence of erroneous cases as noises and the non uniform ...

The complex sentences of newswire reports contain oating content units that appear to be op-portunistically placed where the form of the surrounding text allows. We present a corpus analysis that identiied precise semantic and syntactic constraints on where and how such information is realized. The result is a set of revision tools that form the rule base for a report generation system, allowin...

We propose a framework based on Hierarchical Clustering (HC) to perform multiagent negotiations where we can specify the type of agreements needed in terms of utility sharing among the agents.The proposed multi-round mediation process is based on the analysis of the agents’ offers at each negotiation round and the generation of a social contract at each round as a feedback to the agents, which ...

For the Affective Text task at SemEval2007, University Paris 7’s system first evaluates emotion and valence on all words of a news headline (using enriched versions of SentiWordNet and a subset of WordNetAffect). We use a parser to find the head word, considering that it has a major importance. We also detect contrasts (between positive and negative words) that shift valence. Our knowledge-base...

The growing globalization of business is making face-to-face communications, decision-making, and negotiations more the exception than the rule. Internet communication in text-only, audio, and video form are all becoming feasible methods of communication between distantly located parties. However, in order for these new technologies to be used most effectively, more investigation is needed into...

This paper describes our experiences of using scenarios to design a `knowledge mediating' CBR system. We show how we built negotiated descriptions of decisions made by the business, how these descriptions emerged through processes of negotiation and reenement and how we envisaged ways in which work processes would be transformed by our new system. We argue that envisaging the changing context o...

This paper describes our participation at the RepLab 2012 profiling scenario, in both polarity classification and filtering subtasks. Our approach is based on 1) the information provided by a semantic model that includes rules and resources annotated for sentiment analysis, 2) a detailed morphosyntactic analysis of the input text that allows to lemmatize and divide the text into segments to be ...

The framework of dimensional analysis is used for case-based reasoning. For all case descriptions in engineering and physics consisting of real-valued quantities with physical units, the Pi-Theorem of Buckingham can be shown to derive appropriate similarity conditions and provide an appropriate case adaptation. The advantages of the Pi-Theorem are mainly based on the properties of the so-called...

The Peter principle has been recently investigated by means of an agent-based simulation and its validity has been numerically corroborated. It has been confirmed that, within certain conditions, it can really influence in a negative way the efficiency of a pyramidal organization adopting meritocratic promotions. It was also found that, in order to bypass these effects, alternative promotion st...
