A multi-layered software architecture model for building software solutions in an urbanized information system

The concept of Information Systems urbanization has been proposed since the late 1990’s in order to help organizations building agile information systems. Nevertheless, despite the advantages of this concept, it remains too descriptive and presents many weaknesses. In particular, there is a lack of useful architecture models dedicated to defining software solutions compliant with information systems urbanization principles and rules. Moreover, well-known software architecture models do not provide sufficient resources to address the requirements and constraints of urbanized information systems. In this paper, we draw on the “information city” framework to propose a model of software architecture - called the 5+1 Software Architecture Model - which is compliant with information systems urbanization principles and helps organizations building urbanized software solutions. This framework improves the well-established software architecture models and allows the integration of new architectural paradigms. Furthermore, the proposed model contributes to the implementation of information systems urbanization in several ways. On the one hand, this model devotes a specific layer to applications integration and software reuse. On the other hand, it contributes to the information system agility and scalability due to its conformity to the separation of concerns principle

Cross-Dataset Design Discussion Mining

Being able to identify software discussions that are primarily about design, which we call design mining, can improve documentation and maintenance of software systems. Existing design mining approaches have good classification performance using natural language processing (NLP) techniques, but the conclusion stability of these approaches is generally poor. A classifier trained on a given dataset of software projects has so far not worked well on different artifacts or different datasets. In this study, we replicate and synthesize these earlier results in a meta-analysis. We then apply recent work in transfer learning for NLP to the problem of design mining. However, for our datasets, these deep transfer learning classifiers perform no better than less complex classifiers. We conclude by discussing some reasons behind the transfer learning approach to design mining.Comment: accepted for SANER 2020, Feb, London, ON. 12 pages.
