Both neural networks give promising results.","PeriodicalId":320146,"journal":{"name":"2008 IEEE International Conference on Computational Cybernetics","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131014321","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}

Different approaches of software development emphasize the use of models at all phases of the design and implementation. With metamodels, we can define the concepts of models in concrete domains. Model transformations are used to convert models to other ones. To define rules of transformations, we need to declare, which part of the input models has to be converted. By means of metamodels we can define more complex structures to be matched. In this case we need to find an instance of the defined metamodel in the input graph. The efficiency of the matching algorithms is critical during the application of model transformations. In this paper, a matching algorithm is presented that is able to find all instances of metamodels in arbitrary input models.","PeriodicalId":320146,"journal":{"name":"2008 IEEE International Conference on Computational Cybernetics","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120915151","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}

Application of an integrated product model has a chance of establishment of highly efficient processes for product definition. Product modeling has reached a level where sophisticated representations of object data and relationships are available at every day engineering activities. This information based model is defined by the authors as classical product model. The problem is at the application of this model because information in it is a result of a complex human thinking process content of which is not communicated with the model from the decision maker to the engineer who applies or revises the model. In this paper, the authors introduce their approach and method for a product model that is suitable for better communication between human and processes at generation of classical product model. After a short introduction of related research works, the authors analyzed the changed role of knowledge in product definition. Following this, knowledge and human intent are discussed in order to establish human intent based knowledge representations in product model. In the rest of the paper, the authors introduce the concept of content of product information and propose a multilevel structure for integrated information and information content based product modeling. Finally, future research and implementation are outlined.","PeriodicalId":320146,"journal":{"name":"2008 IEEE International Conference on Computational Cybernetics","volume":"17 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132110792","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}
