    Narrowing the Business-IT Gap in Process Performance Measurement
    van der Aa, Han; Del Río Ortega, Adela; Resinas Arias de Reyna, Manuel; Leopold, Henrik; Ruiz Cortés, Antonio; Mendling, Jan; Reijers, Hajo A.. Actas de las XIII Jornadas de Ingeniería de Ciencia e Ingeniería de Servicios (JCIS 2017), 2017-07-19.
    Process Performance indicators (PPIs) play an important role in monitoring the performance of operational procedures. Both defining and measuring suitable PPIs are key tasks for aligning strategic business objectives with the operational implementation of a process. A major challenge in this regard is that perspectives on the same real-world phenomenon differ among the stakeholders that are involved in these tasks. Since the formulation of PPIs is typically a managerial concern, there is a risk that these do not match with the exact operational and technical characteristics of business processes. To bridge this gap, the concepts described in PPIs must first be linked to their corresponding process elements. Establishing these links is paramount for the monitoring of process performance. Without them, the values of PPIs cannot be computed automatically. However, the necessary links must currently be established manually. A task which is tedious and error-prone, due to the aforementioned incoherence between the different perspectives. The goal of our work is to overcome the efforts involved in the manual creation of links by automating this step. To achieve this, we developed an approach that automatically aligns textual PPI descriptions to the relevant parts of a process model. The approach takes a textual PPI description and a process model to which the PPI relates as input. Given this input, the approach generates an alignment in three steps. (1) Type classification: We make use of a decision tree classifier to identify the type of a given PPI, which is important because it affects the number and kinds of process model elements that should be aligned to a PPI. (2) PPI parsing: We parse the textual PPI description to extract those phrases that relate to specific parts of a process, making use of natural language processing techniques. (3) Alignment to process model: Finally, given the identified measure type and the extracted phrases, we compute an alignment between the phrases and the process model. A quantitative evaluation with a set of 173 PPIs obtained from industry and reference frameworks, demonstrates that our automated approach produces satisfying results.

    Modelling Citizen Letters for Public Services automation
    Gutiérrez-Fernández, Antonio Manuel; Massena, Fernanda; Cappelli, Claudia; Resinas Arias de Reyna, Manuel; Santoro, Flavia; Ruiz Cortés, Antonio. Actas de las XIII Jornadas de Ingeniería de Ciencia e Ingeniería de Servicios (JCIS 2017), 2017-07-19.
    The publication and, when it is possible, automation of public services on Internet provides advantages for citizens and governance. The former because promotes the transparency and control over governance actions and avoids unneeded presencial inquiries and the latter because information systems help to decrease human resources costs. A number of efforts have been performed by public administrations to provide precise service information online. As this service information is incrementally published, manual interaction to navigate and query these services becomes a difficult task that automated mechanisms could support based on service catalogs. In this paper we introduce an ongoing work proposing the use of ontologies to enable the automated processing -i.e. search and validation- of these service catalogs.

    Analyzer4BPEL: Una herramienta de análisis de composiciones WS-BPEL para su aplicación en la etapa de prueba del software
    Valle-Gómez, Kevin J.; de Castro-Cabrera, M. Carmen; Medina Bulo, María Inmaculada. Actas de las XIII Jornadas de Ingeniería de Ciencia e Ingeniería de Servicios (JCIS 2017), 2017-07-19.
    Toda herramienta de prueba de software requiere en algún momento de su proceso realizar un análisis, o bien como primer paso, para extraer la información necesaria para aplicar una determinada técnica, o bien, una vez procesado el software para estudiar los resultados y evaluarlos. Existen en la actualidad herramientas capaces de analizar la mayoría de los lenguajes de programación. Sin embargo, no abundan los analizadores de lenguajes para composiciones de servicios. En este trabajo se presenta una aplicación que realiza un análisis de composiciones en lenguaje WS-BPEL y de sus casos de prueba para extraer información útil para diversos objetivos. Así mismo, se describe su utilización particular, en una de las etapas de la aplicación de una técnica de prueba de software: la prueba metamórfica.

    Towards SLA modeling for RESTful APIs
    Gámez-Díaz, Antonio; Fernández Montes, Pablo; Ruiz Cortés, Antonio. Actas de las XIII Jornadas de Ingeniería de Ciencia e Ingeniería de Servicios (JCIS 2017), 2017-07-19.
    The term of API Economy is becoming increasingly used to describe the change of vision in how APIs can add value to the organizations. Furthermore, a greater automation of RESTful APIs management can suppose a competitive advantage for the company. New proposals are emerging in order to automatize some API governance tasks and increase the ease of use (e.g. generation of code and documentation). Despite that, the non-functional aspects are often addressed in a highly specific manner or even there not exists any solution for an automatic governance. Nevertheless, these properties are already defined in natural language at the Service Level Agreement (SLA) that both customer and provided have established. In this paper, we carry out a study on the *aaS industry and analyze the current both API modeling and SLA modeling proposals in order to identify the open challenges for an automatic RESTful API governance.
