One way to enhance the capability of an information system is to consider its conceptual model quality as well as its functional behaviour. Conceptual model quality can be defined as a set of perceivable characteristics expressed with quantifiable parameters. The aim of this empirical investigation is to evaluate the quality of different potential conceptual models of the same universe of discourse by different Information Systems (IS) stakeholders. This paper describes: a) a set of quality factors (clarity, simplicity, expressiveness, minimality) applied to different versions of entity-relationship (ER) conceptual schemas, b) an approach enabling a comprehensive comparison of the conceptual schemas, c) an experimentation leading to the evaluation of the same schemas by IS stakeholders such as designers, end-users, and students, based on a sample of about 120 observations using different statistical methods. First results indicate that there exists a strong independence between the IS stakeholders and the quality factors used. A second result reveals a significant difference between groups of respondents in their ways to perceive conceptual schemaspsila quality. Based on our experiment, we are able to identify quality factors relevant to different groups of stakeholders, depending on several dimensions, such as their professional experience, and/or their specialization degree.","PeriodicalId":416272,"journal":{"name":"2008 Second International Conference on Research Challenges in Information Science","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126403592","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}

In this paper, we focus on the special class of pattern mining problems known to be dasiarepresentable as setspsila. The main contribution of this paper is to take advantage of the common theoretical background of these problems from an implementation point of view by providing efficient data structures for boolean lattice representation and several implementations of well known algorithms. By the way, these problems can be implemented with only minimal effort, i.e. programmers do not have to be aware of low level code, customized data structures and algorithms being available for free. A toolkit, called iZi, has been devised and applied to several problems such as itemset mining, constraint mining in relational databases and query rewriting in data integration systems. According to our first results, the programs obtained using our toolkit offer a very good tradeoff between performances and development simplicity. Some methodological guidelines are also provided to guide the programmers both at the theoretical level and at the code level.","PeriodicalId":416272,"journal":{"name":"2008 Second International Conference on Research Challenges in Information Science","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114705295","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}

Even if support for this activity appears to be well handed by current sophisticated solutions, the definition and the exploitation of an access rights management framework appropriately adapted for a company remain challenging. This statement is explained mainly by the continuous growth of the diversity of stakeholderspsila positions and by the criticality of the resources to protect. The SIM project, which stands for ldquoSecure Identity Managementrdquo, addresses this problem. The objectives of our paper are twofold. First, to make rights management align closer to business objectives by providing an innovative approach that focuses on business goals for defining access policy. The ISO/IEC 15504 process-based assessment model has been preferred for that research. Indeed, the structured framework that it offers for the description of activities allows for the establishment of meaningful links with responsibilities concepts. Secondly, to automate the deployment of policies through the company IT infrastructurepsilas components and devices by defining a multi-agent system architecture that provides autonomy and adaptability. Free and open source components have been used for the prototyping phase.","PeriodicalId":416272,"journal":{"name":"2008 Second International Conference on Research Challenges in Information Science","volume":"416 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117304830","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}
