Interoperability is the ability of heterogeneous systems to communicate with another system transparently. Usually, interoperability is classified into syntactic, semantic, and pragmatic. The syntactic level is related to the grammar and vocabulary of the message swapped, the semantic level with the meaning of the data and the pragmatic level with the understanding of the messages sent and received. A set of systems is pragmatically interoperable when they share the same expectations about the effect of messages exchanged between them. Due to the vast diversity of definitions and no consensus, provide a pragmatic interoperability solution is a challenge. In this paper, we propose a conceptual framework that aims to contribute to the unification of the concept of pragmatic interoperability and common elements necessary for its realization. For this, a unified definition and conceptual framework are presented. The framework was applied in three different scenarios to demonstrate its applicability and, consequently, validation of the unified concept.

Monitoring systems are essential for prompt action in case of a disaster, as well as for understanding these systems as constituent systems within a System-of-Systems (SoS) can provide new and unique features that cannot be provided by any individual system separately. Furthermore, the identification of existing stakeholders also plays an important role, as constituent systems may be associated with multiple requirements. Therefore, this work presents two artifacts -a conceptual architecture and a stakeholder map - of a SoS for disaster monitoring and early-warning. A Design Science Research (DSR) within a Brazilian early-warning center has been conducted for designing and evaluating the artifacts. An artifact generalization approach has been also employed for generalizing the artifacts from a specific to a broader and generic scenario. Study findings showed that a SoS for disaster monitoring and early-warning should comprise nine constituents, which are used by four groups of stakeholders.

Business Process Model and Notation (BPMN) is an OMG and ISO standard for business process modeling and a standard in professional practice. However, business processes are not static and often need to be tailored to specific contexts where they will be applied or improved as a result of new business requirements. In such contexts, adaptations are performed to produce new variant processes that meet new needs. Ideally, adaptations should be managed in some way in order to prevent organizations from having repositories containing numerous variant models for the same business process without any relationship established between them. Since the BPMN standard does not provide any adaptation support for processes specified with the language, the objective of this paper was to investigate which approaches/techniques have already been proposed in the literature to manage design-time adaptations of process models in BPMN. We have conducted a systematic literature review that resulted in 11 selected works. This review showed that design-time variations on BPMN processes are managed through variability modelling (6 works) or flexible changes (5 works); there are few process adaptation approaches specifically designed for the BPMN language; and such approaches are still quite immature.

This paper proposes an approach to managing software projects that are susceptible to frequent and intense change requests demanding quick response time. Highly influenced by agile thinking, in particular, SCRUM, Kanban and Lean Software development, this solution directly captures the philosophy and the main techniques of these popular agile "methodologies". Moreover, it includes the use of specific measures to manage the project's health and give accurate information to the top level management. This proposal's focus is on improving and optimizing the maintenance process of large-scale information systems which daily handle the change requests of thousands of users. The application of this approach in a real study case allowed to obtain significant results that indicate the potential of the proposal.

Several studies have investigated how to use Machine Learning algorithms to recognize users based on keystroke dynamic. All those studies required Feature Engineering (FE), i.e., a process in which specialists choose what attributes should be considered for learning. However, this process is susceptible to problems such as original information loss or inappropriate attribute choices. Thus, the objective of this work is to demonstrate the hypothesis that user recognition algorithms applied to keystroke dynamics raw (original) data can perform better than the ones that depend on FE. Therefore, this work proposes a deep neural network named DRK. The proposed network contains layers that learn adequate data representations to perform user recognition based on keystroke dynamics raw data, avoiding FE. Experiments compared DRK with four other deep neural networks that use FE in four datasets with 280 users. The proposed network achieved better results in all datasets, showing strong evidence that the stated hypothesis is, in fact, valid.

Several approaches to measure similarity between UML models have been proposed in recent years. However, they usually fall short of what was expected in terms of precision and sensitivity. Consequently, software developers end up using imprecise, similarity-measuring approaches to figure out how similar design models of fast-changing information systems are. This article proposes UMLSim, which is a hybrid approach to measure similarity between UML models. It brings an innovative approach by using multiple criteria to quantify how UML models are similar, including semantic, syntactic, structural, and design criteria. A case study was conducted to compare the UMLSim with five state-of-the-art approaches through six evaluation scenarios, in which the similarity between realistic UML models was computed. Our results, supported by empirical evidence, show that, on average, the UML-Sim presented high values for precision (0.93), recall (0.63) and f-measure (0.67) metrics, excelling the state-of-the-art approaches. The empirical knowledge and insights that are produced may serve as a starting point for future works. The results are encouraging and show the potential for using UMLSim in real-world settings.

Money laundering is a method used by criminals to give lawful appearance to funds obtained illegally. Due to the difficulty of identification using traditional methods of research, technology has played an important role in this process. The knowledge discovery techniques were used in an experimental research with the objective of verifying their effectiveness and accuracy in the identification of relationships in banking transactions from real money laundering investigations. The graph matching techniques obtained the best results but it was found that, despite the low efficiency, frequent pattern mining techniques are important and should not be avoided.

Link prediction is a graph mining task that aims to identify pairs of non-connected vertices that have a high probability to connect in the future. This task has been frequently implemented by recommendation systems that suggest new interactions between users in social networks. In general, the state-of-the-art link prediction methods only consider data from the most complete and recent state of the network. They do not take into account information about the existing topology when new edges were added to the network's structure. This study raises the hypothesis that recovering such data may contribute to building predictive models more precise than the available ones since those data enrich the description of the application's context with examples that represent exactly the kind of event to be foreseen: the appearance of new connections. Hence, this paper evaluates such hypothesis. For this purpose, it proposes a link prediction method that is based on the historical evolution of the topologies of social networks. Results from experiments with ten real coauthorship social networks reveal the adequacy of the proposed method and the confirmation of the raised hypothesis.

In the last few years, several new tools addressing maturity level management have been proposed, e.g. diagnostic assessment questionnaires (DAQ). In practice, the usage of questionnaires presents some drawbacks related to subjectivity, time cost, and applicant bias. Moreover, the questionnaires may present a large number of questions, as well as part of them redundant. Another important fact of real-life application of DAQs concerns the usage of multiple questionnaires, increasing the shortcoming impacts. To pave the way to a more convenient tool to support and facilitate the achievement of organizational strategies and objectives, we proposed an intelligent reduction of DAQs by the use of single-label and multilabel feature selection. In this paper, we reduced four DAQs (Risk Management, Infrastructure, Governance and Service Catalogs) with our proposal in comparison to different feature selection algorithms (χ2, Information Gain, Random Forest Importance and ReliefF). The reduction was driven by a machine learning prediction model towards ensuring the new subset of question grounded in the same obtained score result. Results showed that removing irrelevant and/or redundant question it was possible to increase the model fitting even reducing about one-third of the questions with the same predictive capacity.

The integration of feature models plays a key role in many software engineering tasks, e.g., adding new features to software product lines (SPL) of information systems. Previous empirical studies have revealed that integrating design models is still considered a time-consuming and error-prone task. Unfortunately, integration approaches with tool support are still severely lacking. Even worse, little is known about the effort invested by developers to integrate models manually, and how correct the integrated models are. This paper proposes FMIT, which is a semiautomatic tool to support the integration of feature models. It comes up with a strategy-based approach to reduce the effort that developers invest to combine feature models and increase the amount of correctly integrated models. A controlled experiment was run with 10 volunteers through six realistic integration scenarios. Our results, supported by statistical tests, show that our semiautomatic approach not only reduced the integration effort by 73.01%, but also increased the number of correctly integrated feature models by 43.01%, compared with the manual approach. Our main contributions are a semiautomatic, strategy-based approach with tool support, and empirical evidence on its benefits. Our encouraging results open the way for the development of new heuristics and tools to support developers during the evolution of feature models.
