Abstract. During life cycle of software systems, they can be modified and adapted to the new features. These modifications can increase the complexity of software systems and decrease your quality. One way to improve your quality is to apply transformations in programs, more specifically, refactoring. One of the activities in the refactoring process proposed by Piveta (2009) is Select Refactoring Patterns. This activity selects a set of refactoring patterns to apply in a software system. From that scenario, this survey propose: (i) Refactoring knowledge representation through OWL ontology; (ii) Using the proposed ontology as database for selecting a set of refactoring to be applied in software system. For this a Java application was developed using Jena API. This application makes it easier the activity Select Refactoring Patterns.Resumo. Durante o ciclo de vida dos sistemas de software, eles precisam ser melhorados, modificados e adaptados a novas funcionalidades. Tais modificações podem aumentar a complexidade e diminuir sua qualidade. Uma das maneiras de melhorar sua qualidadeé aplicar transformações, mais especificamente, refatorações. Uma das atividades do processo de refatoração proposto por Piveta (2009),é a seleção do conjunto de refatorações a serem aplicadas em um sistema de software. A partir desse cenário, este trabalho tem como objetivo: (i) Representar o conhecimento de refatoração através de uma ontologia OWL; (ii) Utilizar a ontologia proposta como base de dados para selecionar o conjunto de refatorações a serem aplicadas. A fim de facilitar a seleção, desenvolveu-se uma aplicação Java utilizando a API Jena. Essa possibilita filtrar as refatorações por algumas características como vantagem e domínio. IntroduçãoAtualmente empresas como Google, Microsoft e IBM vem adotando métodoságeis em alguns dos seus projetos. Eles surgiram na década de 90 a fim de desburocratizar os processos tradicionais de desenvolvimento de software. Uma das práticas utilizadas para auxiliar no desenvolvimento, manutenção e na gerência dos sistemas de software, por essas metodologias,é a refatoração [Stellman and Greene 2013].De acordo com Mens and Tourwe (2004), os sistemas de software tendem a evoluir em curtos períodos de tempo, buscando atender novos requisitos. Para isso, tais sistemas precisam ser melhorados, modificados e adaptados a esses novos requisitos. Essas modificações tendem a aumentar a complexidade desses sistemas e diminuir a sua qualidade e quanto mais complexo for um sistema de software, mais custosa será sua 74

“…Representation of ontology changes using higher-level change operations was first proposed by Stojanovic [14] and Klein [19]. Recently, some researchers have focused on representation and detection of higher-level ontology changes [9,20]. Stojanovic choose the evolution logs in order to record the applied changes.…”

To date, no ontology change management system exists that records the ontology changes based on the different levels of granularity. Once changes are performed using elementary level change operations, they are recorded in the database at the elementary level accordingly. Such a change representation procedure is not sufficient to represent the intuition behind any applied change and thus, cannot capture the semantic impact of a change. In this paper, we discuss recording of the applied ontology changes in the form of a layered change log. We support the implementation of a layered change operator framework through layered change logs. We utilize the lower level ontology change log in two ways, i.e. recording of applied ontology changes (operational) and mining of higher level change patterns (analytical). The higher level change logs capture the objective of the ontology changes at a higher level of granularity and support a comprehensive understanding of the ontology evolution. The knowledge-based change log facilitates the detection of similarities within different time series, mining of change patterns and reuse of knowledge.The layered change logs are formalised using a graphbased approach.

In [35], the author proposed a language that allows formulating the intuition behind any applied change in an RDF graph and provided the change detection algorithm with respect to the proposed language.…”

“…Yet, discovery of change patterns from ontology change logs is relatively different from sequential pattern discovery in other contexts (such as the biomedical domain). Recently, few researchers have focused on detection of higher level generic ontology changes [14,35]. In contrast to their work, our approach is to discover the change patterns and is based on contextaware, semantic matching of different graph sequences.…”

Ontology Change Management and Identification of Change Patterns

Ontologies can support a variety of purposes, ranging from capturing the conceptual knowledge to the organisation of digital content and information. However, information systems are always subject to change and ontology change management can pose challenges. In this sense, the application and representation of ontology changes in terms of higher-level change operations can describe more meaningful semantics behind the applied change. In this paper, we propose a four-phase process that covers the operationalization, representation and detection of higher-level changes in ontology evolution life cycle. We present different levels of change operators based on the granularity and domain-specificity of changes. The first layer is based on generic atomic level change operators, whereas the next two layers are user-defined (generic/domain-specific) change patterns. We introduce layered change logs for the explicit operational representation of ontology changes. We formalised the change log using a graph-based approach. We introduce a technique to identify composite changes that not only assists in formulating ontology change log data in a more concise manner, but also helps in realizing the semantics and intent behind any applied change. Furthermore, we identify frequent change sequences that are applied as a reference to discover reusable, often domain-specific and usage-driven change patterns. We describe the pattern identification algorithms and evaluate their performance.
