Abstract
This work describes the design, development and evaluation of a software Prototype, named ArchReco, an educational tool that employs two types of Context-aware Recommendations of Design Patterns, to support users (CS students or professionals) who want to improve their design skills when it comes to training for High Level Software models. The tool’s underlying algorithms take advantage of Semantic Web technologies, and the usage of Content based analysis for the computation of non-personalized recommendations for Design Patterns. The recommendations’ objective is to support users in functions such as finding the most suitable Design Pattern to use according to the working context, learn the meaning, objectives and usages of each Design Pattern. The current work presents the Semantic Modeling of the Software Design process through the definition of the context that defines the Software Design process and in particular the representation of the Design Patterns as Ontology model, the implemented Context Aware Recommendation Algorithms and the evaluation results extracted from a user based testing for the ArchReco prototype.
Highlights
Design Patterns, as defined in (Alexander et al 1977), are a well-known and frequently used software engineering problem-solving discipline, which has emerged from the object-oriented community

The description of the shapes and the purpose of use for each shape, are used as part of a contextual elements set that is processed by the system for the computation of the most suitable Context-based recommended Design Patterns
Summary
Design Patterns, as defined in (Alexander et al 1977), are a well-known and frequently used software engineering problem-solving discipline, which has emerged from the object-oriented community. Design Patterns are “templates” that intend to solve particular problems in a specific context The solution of such problems can adopt derived models, provided by one or more individual Design Pattern or their combination, depending on the kind or type of the designed module/component. Buschmann et al (1996) states that “Patterns help you build on the collective experience of skilled software engineers. They capture existing, well-proven experience in software development and help to promote good design practice”. Following this statement, the issue that needs to be investigated is which patterns are the most suitable to use for the design of a module/component under specific conditions. The adoption of a design pattern or a set of patterns relies on how knowledgeable the designer is, related to the existing design model
