1 - IoT Compositions by and for the Crowd

JCIS_2015_submission_10The Internet of Things (IoT) offers a new eco-system of heterogeneous and distributed services that is available anytime and anywhere and that can be potentially accessed by any properly connected device. However, these available services are usually consumed in isolation, missing the potential that their combined usage can bring as new added-value services. In addition, the massive end-user adoption and usage of smartphones together with their powerful capabilities turn this type of devices into a promising platform to develop and execute these added-value services compositions. Moreover, end-users are nowadays getting more and more familiar with technology, fact that allows them to participate more actively in the development of new types of applications. However, this will not happen until we provide end-users with more powerful and easy-to-use tools. To this end, this paper presents an architectural solution to allow end-users building IoT services compositions by just focusing on domain-logic issues.

2 - A Mobile End-User Tool for Service Compositions

With the advent of Web 2.0 and the massive adoption of smartphones, end-users are more keen to actively participate in the creation of content for the Internet. In addition, the big amount of data that the Internet of Things can bring to it, establishes an ideal framework to allow end-users not just consuming data but also creating new valueadded services. To achieve this, in this work we propose the development of an end-user tool for smartphones capable of composing services that are available in the Internet.

3 - Feature Modeling to deal with Variability in Business Process Perspectives

The construction of Business Process (BP) models entails big challenges, especially when BPs contain many variations. In addition, BPs can be seen from different perspectives, i.e., the behavioral (i.e., control-flow), the organizational (i.e., resources distribution), or the informational (data-flow) perspectives among others. Depending on the context where the BP is taken place, we may found variability in any of these perspectives. Different approaches to model variability in BP perspectives have already been proposed. However, these approaches are highly tight to the modeling language. In addition, they focus mainly on the behavioral perspective. To deal with variability in other BP perspectives in a more flexible manner, this work proposes an approach based on feature models. These models do not only allow enhancing expressiveness regarding BP variability, but also the maintenance and understanding of the resulting process model.

4 - Moskitt4SPL: Tool Support for Developing Self-Adaptive Systems

Increasingly, software needs to dynamically adapt its behavior at runtime in response to changing conditions in the supporting computing, communication infrastructure, and in the surrounding physical environment [6]. Self-adaptive software systems are able to reconfigure at run-time to adapt to changes. The implementation of ad-hoc solutions to cover all possible system configurations and reconfigurations is not feasible. Dynamic Software Product Lines (DSPLs) provide a systematic basis for the engineering of selfadaptive systems [4]. A key characteristic in DSPLs is the intensive use of variability at run-time in order to adapt the system configuration caused by an environment change. Following this approach, a self-adaptive system can be seen as a family of feasible system configurations with a mechanism to move from one configuration to another. The development of self-adaptive systems involves great complexity and becomes a tedious task. We propose Moskitt4SPL (M4SPL) an open-source tool to ease the development of self-adaptive systems. In this tool, we combine model-driven and DSPLs to better cope with the complexities during the construction of self-adaptive systems. M4SPL can be used for modeling systems which make use of variability at run-time in order to adapt the system configuration caused by an environment change. M4SPL provides edition capabilities for Feature Models, Configuration Models and Resolution Models which are part of a self-adaptive system specification. Furthermore, M4SPL incorporates a series of refinements to automatically ensure interesting behavior issues in adaptation specifications. Dealing with those issues before execution is essential for reliable selfadaptive systems that fulfill many of the user’s needs. M4SPL can be used standalone as an Eclipse plug-in or integrated in the MDE MOSKitt environment.

5 - Evolución de Sistemas Auto-Adaptables mediante Modelos en Tiempo de Ejecución

La auto-adaptación se está convirtiendo en un requisito indispensable en los sistemas software. Los sistemas auto-adaptables son capaces de adaptar dinámicamente su comportamiento y estructura en ejecución en respuesta a variaciones en el sistema y el entorno. Los enfoques actuales de auto-adaptación tienden a asumir un mundo cerrado, en el que todos los fenómenos de interés son previstos en tiempo de diseño. Sin embargo, algunos comportamientos adaptativos no se pueden prever a priori. En este ámbito, se requieren técnicas que den soporte a la evolución en tiempo de ejecución de sistemas auto-adaptables. Este artículo propone una aproximación dirigida por modelos para desarrollar y evolucionar de forma sistemática sistemas auto-adaptables mientras están en ejecución. Específicamente, la aproximación utiliza Modelos en Tiempo de Ejecución para incorporar nuevas capacidades que no fueron previstas en el diseño inicial del sistema.

7 - Defining PPIs for Process Variants based on Change Patterns

Business Process (BP) families are made up of BP variants that share commonalities but also show differences to accommodate the specific necessities of different application contexts (i.e., country regulations, industrial domain, etc.). Even though there are modelling techniques to represent these families (e.g., C-EPC, Provop), there is no work aimed at the performance measurement of the different BP variants that conform the family. Process Performance Indicators (PPI) are commonly used to study and analyse the performance of business processes. However, the application of such indicators in BP families increases the modelling and management complexity of the whole family. To deal with this complexity, this work introduces a modelling solution for managing PPI variability based on the concepts of change patterns for process families (CP4PF). The proposed solution includes a set of patterns aimed at 1) reducing the number of operations required to specify PPIs and 2) ensuring PPI family correctness.

9 - Towards a Social End-user Composition of Services

Nowadays, end-users’ environment is plenty of services that support their life style, and involving them in the process of service creation can allows them to benefit from a cheaper, faster, and better service provisioning. There are already tools targeted to the authoring and
consumption of services. However these tools consider end-users as isolated individuals, missing the potential that their social environment can bring to them. In this paper, we investigate how social networks can be used to improve the authoring and consumption of services by end-users. We propose a social network of service compositions as a valuable
mechanism to share knowledge among end-users in order to improve their skills in composing new services. In addition, we analyse the underlying relationships created among service compositions in order to provide end-users with an intuitive way of browsing them.

10 - Diseñando la Participación del Humano en los Sistemas Autónomos

Estamos entrando gradualmente en la era de los sistemas que pretenden dotar de capacidades de computación autónoma a servicios cotidianos. La búsqueda de la autonomía completa es un reto que se está persiguiendo en diversos ámbitos de aplicación y sectores industriales. Sin embargo, la realidad es que la variedad de sistemas, dominios, entornos y contextos de ejecución, restricciones legales y sociales, hace vislumbrar un mundo donde esta autonomía completa será una utopía a corto y medio plazo. En los escenarios en que el sistema autónomo no pueda automatizar completamente sus tareas, se requerirá pues de la participación humana. Desde un punto de vista ingenieril la colaboración entre el humano y estos sistemas (Human in the Loop) introduce un considerable número de retos y problemas a resolver. En este trabajo se identifican los retos tecnológicos que introduce esta colaboración humano-sistema, y se define un marco conceptual que identifica los aspectos a considerar desde un punto de vista abstracto e ingenieril.

11 - Analizando la Integración Humano-Sistema en Sistemas Autónomos

Los sistemas autónomos (SA) están diseñados para actuar de forma autónoma en gran parte de su trabajo; sin embargo, la autonomía completa es una utopía a medio y corto plazo. Este hecho hace necesario que el humano ayude a completar su funcionalidad (‘human-in-the-loop’). Este tipo de sistemas deben garantizar en todo momento un correcto funcionamiento autónomo, a la vez que de-be ceder, bajo ciertas condiciones, total o parcialmente el control al humano para la realización de algunas tareas. Esto requiere analizar y diseñar los siste-mas para que involucren al humano de forma adecuada ante situaciones donde no es posible alcanzar la autonomía, procurando garantizar una correcta integración humano-sistema. En este trabajo se proporcionan las bases para analizar y diseñar las interacciones humano-sistema. En este artículo se presenta un análisis que permite identificar los aspectos esenciales de la participación del humano en el SA y se propone una técnica para especificar como integrar el humano y el sistema en las primeras fases de desarrollo. Los coches autónomos se toman como ejemplo para ilustrar la propuesta mediante escenarios reales.

13 - Enhancing EUCalipTool Service Composition through Natural Language Processing

Although end-users have available a lot of on-line services to be con- sumed individually, it is their composed usage what has the potential to create new value-added services for end-users. In this sense, many efforts have been done to allow end-users to compose the services that they need by themselves. However, most of these solutions present two main problems: (1) they provide little support to help end-users to browse interminable lists of services, and (2) they present the blank piece of paper problem, which appears when end-users have to face an empty canvas to define a composition without any help to find the services that better fit their needs. In this paper, we present a solution to im- prove these problems by using natural language processing techniques in order to search and select the services end-users need to accomplish a specific goal. This solution has been implemented in the context of the EUCalipTool platform.
