Illustrated by a case study on collective decision making, this paper addresses how the two types of agent models can be related to each other. First an internal agent model for collective decision making is presented, based on neurological principles. It is shown how by an automated systematic transformation a behavioural model can be obtained, abstracting from the internal states. In addition, an existing behavioural agent model for collective decision making incorporating principles on social diffusion is described. It is shown under which conditions and how by an interpretation mapping the obtained abstracted behavioural agent model can be related to this existing behavioural agent model for collective decision making.","PeriodicalId":145208,"journal":{"name":"Web Intelligence and Agent Systems","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124434211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our strategy deals with how to assign multiple issues to a set of concurrent negotiations. When an agent is confident about a particular peer agent, it uses a packaged approach by negotiating on multiple issues with that peer in a single negotiation job. Otherwise, it uses a pipelined approach by negotiating with the peer one issue at a time in a sequence of negotiation jobs. Hence, the confidence of an agent’s profile or view of other agents is crucial, and that depends on the environment in which the agents operate. Each initiating agent is also motivated to improve both the process and the outcome of its negotiations, taking into account factors such as time spent and messages sent during negotiation. Our experiments show that the adaptive, confidence-based negotiation strategy outperforms the purely pipelined or purely packaged strategy in a variety of aspects.","PeriodicalId":145208,"journal":{"name":"Web Intelligence and Agent Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128799691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamically changing network topologies account for agents joining and leaving the network and the links that are created and removed between agents in a society. In order to construct a dynamically changing network we have adopted a model representing agents as particles colliding in a social space. We demonstrate that the role model agent mechanism for norm emergence works on top of dynamically created network topologies that represent social relationship structures.","PeriodicalId":145208,"journal":{"name":"Web Intelligence and Agent Systems","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114346661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
