Expressing Strategic Variability and Flexibility of Processes: The Map Process Modeling Approach

Rébecca Deneckère
Centre de Recherche en Informatique
Université Paris 1 Panthéon Sorbonne, Paris, France

Abstract. Typical workflow-style process modeling languages have limits when designing processes at strategic level and reasoning on their variability, flexibility and adaptability. The Map process modeling formalism was defined to overcome this difficulty. It offers a new vision of process modelling by adding a strategic level and enabling intention-driven perspective. Indeed, Map focuses on what the process is intended to achieve – the intentions, and on how these intentions can be achieved – the strategies. Various strategies can be defined to reach an intention, allowing in this way to express the variability and flexibility in process enactment. Formally, Map is a process representation system based on a nondeterministic ordering of intentions and strategies. Il also provides guidelines on how to progress in the process map, i.e. guidelines to select the next intention and strategy and then to execute the underpinning activity. At enactment time, the order of execution of process activities is not predefined; the process is constructed dynamically considering various contextual criteria and the choices done by the actors executing the process. The applicability and usefulness of the Map approach was validated in several areas: requirement engineering, method engineering, decision making, enterprise knowledge development, IS engineering, and so on. The tutorial presents and illustrates the Map process modeling approach and invites the attendees to collaboratively create a map process model for a given case.

Data-Driven Requirements Engineering

Xavier Franch [0000-0001-9733-8830]
Universitat Politècnica Catalunya (UPC-BarcelonaTech), Barcelona, Spain

Abstract. In the last years, we are witnessing the advent of data-driven approaches in almost every single software engineering activity, and requirements engineering is not the exception to the rule. The exploitation of data coming from several sources may indeed become an extremely useful input to requirements elicitation and management but it does not come for free. Techniques such as natural language processing and machine learning are difficult to master and require high-quality data, whilst their generalization remains as a challenge. In this tutorial, I introduce the main concepts behind data-driven requirements engineering, then I provide an overview of the state of the art and report on results from some collaborative projects in which I’m participating, and last recapitulate lessons learned and open challenges. The research reported has been possible thanks to the support of the OpenReq (contract 732463) and Q-Rapids (contract 732253) H2020 projects supported by the European Union.

Multi-Level Modeling with Powertypes: What you can do, What you can’t do, and How to achieve more with a foundational theory

João Paulo A. Almeida
Ontology & Conceptual Modeling Research Group (NEMO)
Federal University of Espírito Santo (UFES), Vitória, Brazil

Abstract. In most approaches, a conceptual model is stratified into entities in two levels: (i) a level of types (or classes), and (ii) a level of instances (or objects). This conventional two-level scheme reveals its limitations whenever categories of categories are part of the domain of inquiry. In this case, multiple levels of classification are required—individuals, types, types of types, etc. For decades now, “powertypes” have been employed in such scenarios. Despite their wide applicability, powertypes are not capable of expressing a full multi-level scheme in which types have a dual type-instance nature. The goal of this tutorial is to explore recent advances in powertype-based multi-level representation strategies. Attendees will understand the historical mechanisms, appreciate the limitations of the support for powertype patterns in mainstream languages (such as UML) and will be provided strategies to circumvent these limitations based on a foundational theory for multi-level modeling. The representation strategies include a number of pattern variants accompanied with easy-to-follow (well-founded) modeling rules (most of which can be checked automatically by a modeling tool). Current research on advanced multi-level mechanisms related to the powertype pattern will also be discussed (e.g., concerning attributes of powertypes and their relation to the phenomenon known as deep characterization). Open issues and an agenda for further research will be outlined.

Knowledge acquisition for ontology development

Mara Abel
Computing Systems for Petroleum Exploration & Production Research Group

Abstract: Before designing a software application, the engineer needs to define the conceptual model in order to understand and simplify reality. The model does not represent the reality itself but the intention of the modeler in designing the application, according to his/her previous conceptualization.  In order to guarantee that the software can be further integrated and understood, this conceptualization needs to be shared among the community of users. Ontologies are being developed and applied for explicating the semantics of the models and providing a framework for data interoperability among several applications. They differ from data models in the sense that the semantic is not based on the software application itself, but in the common acquaintance of the terminology among a community along with the philosophical view about world understanding.  This tutorial explains the distinction between knowledge models and ontologies as a motivation for applying distinctive approaches for knowledge acquisition and modeling.  It introduces practical steps and techniques for knowledge acquisition with the focus of producing well-founded domain ontologies. We aim the explanation is useful for general use in conceptual modeling tasks.
