Abstract. Opinion mining is a sub-discipline of computational linguistics that uses information retrieval techniques in order to determine whether a piece of text expresses a positive, negative or neutral opinion. In this paper, we present an approach for the opinion mining of financial news through the process of identifying their semantic polarity. Our approach relies on an algorithm that combines several gazetteer lists and leverages an existing financial ontology. The financialrelated news are obtained from RSS feeds and then automatically annotated with positive or negative markers. The outcome of the process is a set of news organized by their degree of positivity and negativity. The preliminary experimental results seem promising as compared against traditional approaches.

“…The feature distance was evaluated by virtual distance. Many researchers like Tamma et al (2005), Giovannucci et al (2008), Garcia-Sanchez et al (2009) designed negotiation ontology to describe terminologies appeared during the MAS negotiation process to reach semantic interoperability.…”

“…This ontology defined a set of vocabulary, semantic term relations, inference rules and logics. Tamma et al (2005) and Garcia-Sanchez et al (2009) constructed negotiation ontology for describing and supporting knowledge retrieval from MAS participants. Roles and rules of negotiation protocol were defined inside the ontology, which enabled negotiation participants to select proper negotiation protocols flexibly and dynamically.…”

Service-oriented architecture for ontologies supporting multi-agent system negotiations in virtual enterprise

This paper offers a service-oriented architecture (SOA) for ontology-based multi-agent system (MAS) negotiations in the context of virtual enterprises (VEs). The objective of this paper is fourfold. First, it is to design a SOA which utilizes ontology and MAS to provide a distributed and interoperable environment for automated negotiations in VE. In this architecture, individual ontologies for both the VE initiator and its potential partners are constructed to describe and store resources and service knowledge. Second, a series of semantic ontology matching methods are developed to reach agents' interoperability during the negotiation process. Third, correspondence-based extended contract net protocol is presented, which provides basic guidelines for agents' reaching mutual understandings and service negotiation. Last, a fuzzy set theory based knowledge reuse approach is proposed to evaluate the current negotiation behaviors of the VE partners. A walkthrough example is presented to illustrate the methodologies and system architecture proposed in this paper.

“…El prototipo implementado ha sido testado empíricamente sobre tres escenarios de ejemplo en los dominios de e-Comercio [4], bioinformática [3] y e-Administración [5]. El escenario planteado para el dominio de e-Comercio está compuesto por un usuario que desea realizar una compra, y un conjunto de proveedores de productos informáticos que permiten el acceso a sus catálogos de productos a través de servicios Web.…”
