Over the last two decades, much attention has been paid to the area of goal-oriented requirements engineering (GORE), where goals are used as a useful conceptualization to elicit, model, and analyze requirements, capturing alternatives and conflicts. Goal modeling has been adapted and applied to many sub-topics within requirements engineering (RE) and beyond, such as agent orientation, aspect orientation, business intelligence, model-driven development, and security. Despite extensive efforts in this field, the RE community lacks a recent, general systematic literature review of the area. In this work, we present a systematic mapping study, covering the 246 top-cited GORE-related conference and journal papers, according to Scopus. Our literature map addresses several research questions: we classify the types of papers (e.g., proposals, formalizations, meta-studies), look at the presence of evaluation, the topics covered (e.g., security, agents, scenarios), frameworks used, venues, citations, author networks, and overall publication numbers. For most questions, we evaluate trends over time. Our findings show a proliferation of papers with new ideas and few citations, with a small number of authors and papers dominating citations; however, there is a slight rise in papers which build upon past work (implementations, integrations, and extensions). We see a rise in papers concerning adaptation/variability/evolution and a slight rise in case studies. Overall, interest in GORE has increased. We use our analysis results to make recommendations concerning future GORE research and make our data publicly available.

Goal modeling has been adaptedand applied to many sub-topics within RE and beyond, suchas agent-orientation, aspect-orientation, business intelligence, model-driven development, security, and so on. Despite extensiveefforts in this field, the RE community lacks a recent, generalsystematic literature review of the area. As a first step towardsproviding a GORE overview, we present a Systematic LiteratureMap, focusing on GORE-related publications at a high-level, categorizing and analyzing paper information in order to answerseveral research questions, while omitting a detailed analysis ofindividual paper quality. Our Literature Map covers the 246 topcitedGORE-related conference and journal papers, accordingto Scopus, classifying them into a number of descriptive papertypes and topics, providing an analysis of the data, which ismade publicly available. We use our analysis results to makerecommendations concerning future GORE research.

Information practices and systems that make use of personal and health-related information are governed by European laws and regulations to prevent unauthorized use and disclosure. Failure to comply with these laws and regulations results in huge monetary sanctions, which both private companies and public administrations want to avoid. How to comply with these laws, requires understanding the privacy requirements imposed on information systems. A holistic approach to privacy requirements specification calls for understanding not only the requirements derived from law, but also citizens' needs with respect to privacy. In this paper, we report on our experience in conducting privacy requirements engineering as part of a H2020 European Project, namely VisiOn (Visual Privacy Management in User Centric Open Requirements) for the development of a privacy platform to improve the interaction between Public Administrations (PA) and citizens, while guarding the privacy of the latter. Specifically, we present the process for eliciting, classifying, prioritizing, and validating privacy requirements for the two types of users, namely PA and citizen. The process is applied to different cases spanning from healthcare to other e-governmental initiatives, with the active involvement of the corresponding PAs. We report on findings and lessons learned from this experience.

Security Requirements Engineering (SRE) is concerned with the elicitation of security needs and the specification of security requirements of the system-to-be. Current approaches to SRE either express stakeholders' needs via high-level organisational abstractions that are hard to map to system design, or specify only technical security requirements. In this paper, we introduce SecCo, an SRE framework that starts with goal-oriented modelling of the security needs and derives security requirements from such needs. Importantly, SecCo relates security requirements to the interaction among actors. Security requirements are specified as social commitments - promises with contractual validity from one actor to another - that define constraints on the way actors can interact. These commitments shall be implemented by the system-to-be.
