    Assisting software architects in architectural decision-making using Quark

    Non-Functional Requirements (NFRs) and constraints are among the principal drivers of architectural decision-making. NFRs are improved or damaged by architectural decisions (ADs), while constraints directly include or exclude parts of the architecture (e.g., logical components or technologies). We may determine the impact of an AD, or which parts of the architecture are affected by a constraint, but at the end it is hard to know if we are respecting the NFRs and the imposed constraints with all the ADs made. In the usual approach, architects use their own experience to produce software architectures that comply with the NFRs and imposed constraints, but at the end, especially for crucial decisions, the architect has to deal with complex trade-offs between NFRs and juggle with possible incompatibilities raised by the imposed constraints. In this paper we present Quark, a method to assist software architects in architectural decision-making, and the conceptualization of the relationship between NFRs and ADs defined in Arteon, an ontology to represent and manage architectural knowledge. Finally, we provide an overview of the Quark and Arteon implementation, the ArchiTech tool.Peer ReviewedPostprint (published version

    How organisation of architecture documentation affects architectural knowledge retrieval

    A common approach to software architecture documentation in industry projects is the use of file-based documents. This approach offers a single-dimensional arrangement of the architectural knowledge. Knowledge retrieval from file-based architecture documentation is efficient if the organisation of knowledge supports the needs of the readers; otherwise it can be difficult. In this paper, we compare the organisation and retrieval of architectural knowledge in a file-based documentation approach and an ontology-based documentation approach. The ontology-based approach offers a multi-dimensional organisation of architectural knowledge by means of a software ontology and semantic wiki, whereas file-based documentation typically uses hierarchical organisation by directory structure and table of content. We conducted case studies in two companies to study the efficiency and effectiveness of retrieving architectural knowledge from the different organisations of knowledge. We found that the use of better knowledge organisation correlates with the efficiency and effectiveness of AK retrieval. Professionals who used the knowledge organisation found this beneficial

    Mining Architectural Information: A Systematic Mapping Study

    Context: Mining Software Repositories (MSR) has become an essential activity in software development. Mining architectural information to support architecting activities, such as architecture understanding and recovery, has received a significant attention in recent years. However, there is an absence of a comprehensive understanding of the state of research on mining architectural information. Objective: This work aims to identify, analyze, and synthesize the literature on mining architectural information in software repositories in terms of architectural information and sources mined, architecting activities supported, approaches and tools used, and challenges faced. Method: A Systematic Mapping Study (SMS) has been conducted on the literature published between January 2006 and November 2021. Results: Of the 79 primary studies finally selected, 8 categories of architectural information have been mined, among which architectural description is the most mined architectural information; 12 architecting activities can be supported by the mined architectural information, among which architecture understanding is the most supported activity; 81 approaches and 52 tools were proposed and employed in mining architectural information; and 4 types of challenges in mining architectural information were identified. Conclusions: This SMS provides researchers with promising future directions and help practitioners be aware of what approaches and tools can be used to mine what architectural information from what sources to support various architecting activities.Comment: 68 pages, 5 images, 15 tables, Manuscript submitted to a Journal (2022

    Tese (doutorado)—Universidade de Brasília, Faculdade de Ciência da Informação, Programa de Pós-Graduação em Ciência da Informação, 2017.A pesquisa que resultou nesta tese investigou processos de desenvolvimento e de avaliação de vocabulários controlados. Esta tese inclui os seguintes elementos: resultado de pesquisa bibliográfica sobre arquitetura da informação, recuperação da informação, organização da informação e representação da informação; proposta de arcabouço para ciclo de vida de projeto de vocabulário controlado; e exemplo de uso de elementos desse arcabouço na construção de um protótipo de vocabulário controlado no domínio da Engenharia de Software. O arcabouço proposto é composto por arquitetura de referência, modelo de domínio, modelo de qualidade e lista de atividades. Entre os elementos do modelo de qualidade proposto, existe uma lista de características de qualidade de vocabulários controlados. Os modelos propostos estão parcialmente alinhados a ferramentas semânticas existentes.The research that resulted in this thesis has investigated development and evaluation processes of controlled vocabularies. This thesis includes the following elements: results of a bibliographic research on information architecture, information recovery, information organization and information representation; proposal of a framework for controlled vocabulary project life cycle; and example of use of this framework during the construction of a prototype of a controlled vocabulary on the Software Engineering domain. The proposed framework is composed of reference architecture, domain model, quality model and list of activities. Among the elements of the proposed quality model, there is a list of controlled vocabulary quality characteristics. The proposed models are partially aligned to existing semantic tools
