Paper - Business Process Models Quality through Domain Ontologies

Thu, 14 Mar 2013 13:45:54 +0100

This paper addresses the issue of improving quality of business process (BP) models by exploiting domain knowledge. Indeed, business process models reflect the business processes of companies. The success of these processes has a direct and undeniable impact on business operations success. Managing them through their underlying models helps improving their effectiveness, consistency, and transparency. BP modeling aims at a better understanding of processes, allowing deciders to achieve strategic goals of the company. However, several studies from literature showed that inexperienced system analysts often produce low level quality. This situation is partly due to lack of domain knowledge. In this paper we propose to support this modeling effort with an approach that uses domain knowledge to improve the semantic quality of BP models. We suggest to use ontologies as a mean to capture domain knowledge and meta-modeling techniques to deal with BP models independently of languages in which they are expressed. Our contribution is threefold: 1) the meta-models describing both a domain ontology and a BP model are described, 2) the alignment between the concepts of both meta-models is dened and illustrated, 3) a set of OCL (Object Constraint Language) mapping rules is provided. A simple case study illustrates the process.

Prospective authors are invited to submit papers in any of the topics of the workshop. The results described must be unpublished and must not be under review elsewhere. Only papers in English will be accepted. Manuscripts must comply with the Springer NLBIP formatting rules. Prepare your manuscript as a PDF file and submit it to the workshop organizers via the EasyChair system.

We accept three types of submissions: Regular Research Papers, Experience Papers and Demo/Poster Papers.

Regular Research Papers describe original solutions (theoretical, methodological or conceptual) in the field of secure information systems engineering. A regular research paper should describe the context of the work, the problem tackled, the relevant state of the art, the position or solution suggested and the benefits of the contribution. The length of regular research papers should not exceed 12 pages (including all text, figures, references and appendices.). Three to five keywords characterising the paper should be indicated at the end of the abstract.

Experience papers present application of work to case studies and industrial practice. Such papers should provide a detail description of the application setting, describe lessons learned, and discuss best practice. Experience papers should not exceed 12 pages (including all text, figures, references and appendices.). Three to five keywords characterising the paper should be indicated at the end of the abstract.

Demo/Poster papers should briefly discuss academic and/or industrial efforts on software tools and systems for secure information systems engineering. Demo/Poster papers should not exceed 1 page and they should provide a brief description of the research and software/system to be demonstrated. Poster papers are also ideal to explain a new idea and get feedback from the community. It is expected that accepted papers will be presented in the form of a live demonstration or a poster.

Submissions not conforming to the LNCS format and the above page limitations or being obviously out of the scope of the workshop will be rejected without review.
Registration

For each accepted submission, at least one author is expected to register for the workshop and attend the workshop in order to present the paper. Registration is through the CAiSE’13 web site.

Workshop Structure

The workshop will combine paper presentations, poster/demonstration session, and a keynote.

Moreover, accepted papers apart from presentation time, will be assigned with one or two discussants with responsibility to initiate the discussion on the paper. We are confident that such structure will support a workshop environment that will be based on discussion, debate and will therefore provide an important contribution to the relevant research community.

Paper - Domain Knowledge Based Quality for Business Process Models

Tue, 20 Nov 2012 15:09:00 +0100

In recent years the problems related to modeling and improving business processes have been of growing interest. Indeed, companies are realizing the undeniable impact of a better understanding and management of business processes (BP) on the effectiveness, consistency, and transparency of their business operations. BP modeling aims at a better understanding of processes, allowing deciders to achieve strategic goals of the company. However, inexperienced systems analysts often lack domain knowledge leading and this affects the quality of models they produce. In this paper we propose to support this modeling effort with an approach that uses domain knowledge to improve the semantic quality of BP models. This approach relies on domain ontologies as a mean to capture domain knowledge and on metamodeling techniques. The main contribution of this paper is threefold: 1) the metamodels describing both a domain ontology and a BP model are described, 2) the alignment between the concepts of both metamodels is defined and illustrated, 3) a prototype implementing the approach is presented.

Paper - Towards A Semantic Quality Based Approach for Business Process Models Improvement

Tue, 06 Nov 2012 13:29:47 +0100

Business process (BP) modeling aims at a better understanding of processes, allowing deciders to improve them. We propose to support this modeling with an approach encompassing methods and tools for BP models quality measurement and improvement. In this paper we focus on semantic quality. The latter is evaluated by aligning BP model concepts with domain knowledge. The alignment is conducted thanks to meta-models. We also define validation rules for checking the completeness of BP models. A medical case study illustrates the main steps of our approach.

Paper - Building Contextualized Topic Maps

Tue, 30 Oct 2012 18:04:31 +0100

The topic map model is a popular semantic web standard designed to organize contents from various resources and to enhance navigation in these resources. Building manually a topic map from a large content is impossible: a method supported by a tool is required. However, existing methods don?t allow a construction of a contextualized topic map. This paper tackles this problem often encountered when organizing semantically heterogeneous contents. It proposes a model driven approach that builds a topic map to organize a semantically heterogeneous content. This approach uses UML profiles to describe the annotated content as well as the resulting Topic Map. It also uses the reification concept defined in the ODM (Ontology Definition Model) to reflect the semantic heterogeneity of resources to organize.

Paper - Ontology Learning from Databases: Some Efficient Methods to Discover Semantic Patterns in Data

Wed, 12 Sep 2012 18:06:35 +0200

Relational databases are valuable sources for ontology learning. Previous work showed how precise ontologies can be learned and be fruitfully exploited to solve practical problems, such as ensuring integration and interoperation of heterogeneous databases. However, a major persisting limitation of the existing approaches is the derivation of ontologies with flat structure that simply mirror the schema of the source databases. In this paper, we present some efficient methods that show how the content of the databases can be exploited to identify categorization patterns from which class hierarchies can be generated. These data driven methods focused on hierarchy mining in the stored data can be combined with a classical database schema analysis

Paper - Aligning Business Process Models and Domain Knowledge: A Meta-Modeling Approach

Paper - A Framework for Auditing Web-Based Information Systems

Mon, 30 Jul 2012 16:15:23 +0200

The last decade has seen an unprecedented rate of development of Web-Based Information System (WBIS). Enormous investment is currently being made in WBIS systems. There is a concern about whether the true capability of WBIS is being realized. As a consequence, growing attention is being paid to assessing the inherent contribution of WBIS. In this paper, we propose a WBIS audit methodology. The latter has two main features: 1) it structures the audit process as a hierarchical evaluation tree, using an Analytic Hierarchy Process model, 2) it allows the evaluation of a WBIS according to a specific set of criteria based on quality, security and readability requirements. Unlike past approaches, our methodology allows independent auditors, companies and users to minimize the time and effort needed to evaluate WBIS. It has been applied to a real-life example which is described in the paper, allowing us to validate our WBIS audit approach.

Paper - Ontologies for Security Requirements: A Literature Survey and Classification

Wed, 11 Apr 2012 17:30:21 +0200

Despite existing methodologies in the field, most requirements engineers are poorly trained to define security requirements. This is due to a considerable lack of security knowledge. Some security ontologies have been proposed, but a gap still exists between the two fields of security requirement engineering and ontologies. This paper is a survey, it proposes an analysis and a typology of existing security ontologies and their use for requirements definition.

Paper - Vers une nouvelle génération de définition des exigences de sécurité fondée sur l'utilisation des ontologies

Wed, 11 Apr 2012 17:24:07 +0200

Au cours de ces dernières années, la sécurité des Systèmes d'Information (SI) est devenue une préoccupation importante, qui doit être prise en compte dans tous les phases de développement du SI, y compris dans la phase initiale de l'ingénierie des exigences (IE). Des études récentes proposent quelques approches utiles pour la définition des exigences de sécurité. Cependant les analystes continuent de souffrir d'un manque considérable de connaissances sur la sécurité et sur le domaine d'activité des entreprises. Les ontologies sont connues pour être des sources riches de ces connaissances . Nous proposons, dans cette recherche, de mobiliser des ontologies dans le processus d'ingénierie des exigences. Nous voulons montrer que le recours à des ontologies pour supporter ce processus est un facteur clé de succès dans la définition d?exigences de sécurité de haute qualité.

Paper - Transforming multidimensional models into OWL-DL ontologies

Fri, 06 Apr 2012 18:13:15 +0200

Business intelligence is based on data warehouses. Data warehouses use a multidimensional model, which represents relevant facts and their measures according to different dimensions. Based on this model, OLAP cubes may be defined, enabling decision makers to analyze and synthesize data. Ontologies (and, more specifically, OWL ontologies) are a key component of the semantic Web. This paper proposes an approach to represent multidimensional models as OWL-DL ontologies. To this end, it presents the multidimensional metamodel, the concepts of OWL-DL, and transformation rules for mapping a multidimensional model into and OWL-DL ontology. It then illustrates application to a case study with a simplified example of a spatiotemporal data warehouse. The transformation rules are refined to deal with spatiotemporal data warehouses, applied step by step, and the resulting ontology is implemented in the Protégé ontology tool. As illustrated by the case study, our approach enables better formalization and inferencing, thanks to OWL-DL. The ontology may also be used to represent OLAP cubes on the semantic Web (with RDF), by defining these cubes as instances of the OWL-DL multidimensional ontology.

Paper - De l´analyse des risques à l´expression des exigences de sécurité des systèmes d?informations

Fri, 06 Apr 2012 18:10:40 +0200

Il existe différentes méthodologies d'analyse de risques et de détermination des exigences de sécurité. Toutefois, rares sont les démarches qui offrent un guidage permettant de dériver les exigences de sécurité à partir des risques. Cet article propose un mécanisme de guidage qui permet de passer, à l?aide d´un ensemble de règles de transformation, de l´analyse des risques encourus par les entreprises à l´expression des exigences de sécurité. Nous procédons en trois étapes. La première étape est dédiée à la construction d?une ontologie des risques. Nous élaborons dans la seconde étape une ontologie des exigences de sécurité. Lors de la troisième étape, nous proposons un ensemble de règles qui guident le passage de l?ontologie des risques vers celle qui représente les exigences de sécurité. Ces règles de « mapping », représentées sous forme de base de connaissances, sont issues des meilleures pratiques dans le domaine de la sécurité et permettent de garantir la cohésion sémantique de l?alignement entre les deux ontologies. Une étude de cas et un prototype sont décrits.

Paper - Application de la génération de requêtes de médiation au dossier médical personnel

Thu, 05 Apr 2012 00:58:36 +0200

Le Dossier Médical Personnel (DMP) est aujourd?hui une solution qui permet aux patients et aux professionnels de santé de partager des informations en vue de faciliter la coordination et d?éviter les examens inutiles. Par ailleurs, les systèmes de médiation sont aujourd'hui largement développés. Ils peuvent servir entre autres d?outils d?acquisition de données pour alimenter un système d?informations médicales. Nous proposons dans cet article une approche de génération automatique de requêtes de médiation. A partir de la description relationnelle d?un ensemble de sources de données distribuées et hétérogènes, notre algorithme produit un ensemble de requêtes de médiation possibles qui calculent une instance du DMP.

Paper - Efficient Filtering in Micro-blogging Systems: We Won't Get Flooded Again

Wed, 04 Apr 2012 15:44:46 +0200

In the last years, micro-blogging systems have encountered a large success. Twitter for instance claims more than 200 million accounts after 5 years of existence with more than 200 million tweets a day leading to 350 billion delivered tweets. Micro-blogging systems rely on the all-or-nothing paradigm: a user receives all the posts from an account s/he follows. A consequence for a user is the risk of flooding, i.e., the number of posts received from all the accounts s/he follows implies a time-consuming scan of his list of postings to read news that match his interests. Meanwhile these systems receive all posts and deliver each of them to all the followers of the publishing accounts, whether they are interested by the news or not. To avoid user flooding and to significantly diminish the number of posts to be delivered, we propose in this paper three filtering structures for micro-blogging systems. They allow to efficiently retrieve the followers of an account that could be interested by a post s/he published. We compare analytically these structures and confirm our analysis experimentally on synthetical datasets and on a real Twitter dataset which consists of more than 2.1 million users, 15.7 million tweets and 148.5 million publisher-follower relationships.

Paper - CITOM: An Incremental Construction of Topic Maps

Mon, 12 Mar 2012 17:21:07 +0100

This paper proposes the CITOM approach for an incremental construction of multilingual Topic Maps. Our main goal is to facilitate user?s navigation across documents available in different languages. Our approach takes into account three types of information sources: (a) a set of multilingual documents, (b) a domain thesaurus and (c) all the possible questioning sources such as FAQ and user?s or expert?s requests about documents. In this paper we present the different steps of the proposed approach to construct the Topic Map and the pruning process of the generated Topic Map. We validate our approach with a real corpus from the sustainable construction domain.

Paper - Proposition of a generic metamodel for interorganizational business processes

Fri, 17 Feb 2012 18:30:47 +0100

An Interorganizational Business Process (IOBP) is an organized group of related activities carried out by multiple organizations to accomplish a common business goal. A consequence of this is that business process modeling and design used inside an organization have to be enhanced and extended to cope with interorganizational business relationships. Modeling business processes that span multiple organizations involves new challenges, mainly the ability to cope with autonomy, privacy, heterogeneity, and the support for coordination trough mutual agreements. As a contribution to this area, this paper presents a metamodel that captures a wide range of IOBP elements.

Paper - A Quality Pattern Based Approach for the Analysis and Design of Information Systems

Fri, 17 Feb 2012 15:25:57 +0100

Conceptual models (CM) serve as the blueprints of information systems and their quality plays decisive role in the success of the end system. It has been witnessed that majority of the IS change-requests result due to deficient functionalities in the information systems. Therefore, a good analysis and design method should ensure that CM are correct and complete, as they are the communicating mediator between the users and the development team. Our approach targets the problems related to conceptual modeling quality by proposing a comprehensive solution. We designed multiple artifacts for different aspects of CM quality. These artifacts include the following: i. Formulation of comprehensive quality criteria (quality attributes, metrics, etc.) by federating the existing quality frameworks and identifying the quality criteria for gray areas. Most of the existing literature on CM quality evaluation represents disparate and autonomous quality frameworks proposing non-converging solutions. Thus, we synthesized (existing concepts proposed by researchers) and added the new concepts to formulate a comprehensive quality approach for conceptual models that also resulted in federating the existing quality frameworks. ii. Formulation of quality patterns to encapsulate past-experiences and good practices as the selection of relevant quality criteria (including quality attributes and metrics) with respect to a particular requirement (or goal) remains trickier for a non-expert user. These quality patterns encapsulate valuable knowledge in the form of established and better solutions to resolve quality problems in CM. iii. Designing of the guided quality driven process encompassing methods and techniques to evaluate and improve the conceptual models with respect to a specific user requirement or goal. Our process guides the user in formulating the desired quality goal, helps him/her in identifying the relevant quality patterns or quality attributes with respect to the quality goal and finally the process helps in evaluating the quality of the model and propose relevant recommendations for improvement. iv. Development of a software prototype ?CM-Quality?. Our prototype implements all the above mentioned artifacts and proposes a workflow enabling its users to evaluate and improve CMs efficiently and effectively. We conducted a survey to validate the selection of the quality attributes through the above mentioned federating activity and also conducted three step detailed experiment to evaluate the efficacy and efficiency of our overall approach and proposed artifacts.

Paper - Qualité des modèles de données

Fri, 17 Feb 2012 15:00:31 +0100

La dépendance des entreprises et des organisations vis-à-vis de leurs systèmes d?information (SI) n?est plus à démontrer. Cette réalité conduit les décideurs à assurer une qualité acceptable des systèmes d?information. Une des caractéristiques principales de la qualité de ces systèmes est sa nature multidimensionnelle. [STY 00] caractérise la qualité des systèmes d?information au moyen de six dimensions : l?infrastructure, les logiciels, les données, l?information, l?administration et le service rendu. En particulier, Stylianou distingue la qualité des données à l?entrée du SI de la qualité de l?information en sortie. Cette nuance n?est pas reprise dans les autres approches qui ne différencient pas données et information en termes de qualité.

Paper - Federating Information System Quality Frameworks Using A Common Ontology

Fri, 17 Feb 2012 14:48:22 +0100

Information system (IS) quality can be characterized as a multidimensional system. It encompasses software quality as well as data quality. It also comprises model quality, service quality, process quality, and more generally IS quality. Modeling several aspects of IS quality leads to specific ontologies. To the best of our knowledge, there is no global ontology dedicated to all the dimensions of an IS. A single ontology federating all the aspects of quality is not available. The aim of this paper is to propose and discuss the main constituents of an ontology of quality federating all the aspects of IS components quality (software, data, models, etc.). In order to operationalize the proposed ontology, we describe an approach allowing us to use the ontology in order to achieve specific quality goals.

Paper - A pattern-oriented methodology for conceptual modeling evaluation and improvement

Fri, 17 Feb 2012 14:37:20 +0100

Abstract Conceptual models are of prime importance to ensure a high level of quality in designing information systems. It has been witnessed that the majority of information systems (IS) change requests result due to deficient functionalities in the information systems. Therefore, a good analysis and design method should guarantee that conceptual models are correct and complete and easy to understand, as they are the communicating mediator between the users and the development team. Similarly, if models are complex then their extension or the incorporation of missing requirements gets very difficult for the designers. Our approach evaluates the conceptual models on multiple levels of granularity in addition to providing the corrective actions or transformations for improvement. We propose quality patterns to help the non-expert users in evaluating their models with respect to their quality goal. This paper also illustrates our approach by describing an evaluation and improvement process using a case study.

Paper - Projet VIVA : Vivre avec Alzheimer en 2030

Thu, 16 Feb 2012 19:45:53 +0100

Le projet VIVA vise d'une part à explorer et comprendre les problèmes que rencontrent quotidiennement à Paris les personnes souffrant de dégénérescence de mémoire ? spécialement les personnes débutant une maladie d'Alzheimer ? et d'autre part à proposer pour chacun de ces problèmes un ensemble de solutions fondées sur les dernières avancées en matière de technologies informatiques et intégrées à l'habitat et à la Ville . Les résultats du présent projet pourront éclairer les décisions à prendre en matière d'habitat intelligent et d'intelligence ambiante dans la Ville (ville intelligente) pour y faciliter la vie sociale des Parisiens frappés de dégénérescence mnésique.
