Mining unstructured data to support requirements elicitation by using controlled vocabularies: A systematic mapping study

This paper presents a work-in-progress that deals with the assessment of the use of controlled vocabularies during the processes of requirements engineering, as a means to mine data from different sources (interviews, contracts, schemas and diagrams). By doing this the requirements description, analysis and comprehension is facilitated for both developers and end users. As a research methodology, we decided to use a systematic mapping study covering the last fourteen years (2000 - 2014). As far as we know, such studies have not yet been done; however, the cost incurred from errors in the requirements elicitation phase is one of the problems that is most commonly reported by the practitioners. Our study includes data on the processes of building the controlled vocabulary and assesses the productivity and quality. We are also interested in tools and techniques to classify and retrieve information. Our first findings suggest that this is an under-research area

A Controlled Experiment for Assessing the Contribution of Design Pattern Documentation on Software Maintenance

In this paper we present the preliminary results of a controlled experiment to assess the contribution provided by the design patterns on the maintenance of source code. In particular, the study aimed at assessing the effort and the efficiency to perform maintenance operations in case design pattern instances are properly documented and provided to the maintainer. The context of the experiment is constituted of Master Students in Computer Science at the University of Basilicata. The preliminary analysis conducted on the gathered data revealed that the effort is significantly reduced in case design pattern instances are properly documented and provided to the subjects. Similarly, the efficiency is significantly better in case the documentation of design pattern instances is used to accomplish maintenance operations

ANNOTATION MECHANISMS TO MANAGE DESIGN KNOWLEDGE IN COMPLEX PARAMETRIC MODELS AND THEIR EFFECTS ON ALTERATION AND REUSABILITY

El proyecto de investigación propuesto se enmarca dentro del área de diseño de producto con aplicaciones de modelado sólido CAD/CAM (Computer Aided Design/Computer Aided Manufacturing). Concretamente, se pretende hacer un estudio de las herramientas de anotación asociativas disponibles en las aplicaciones comerciales de modelado CAD con el fin de analizar su uso, viabilidad, eficiencia y efectos en la modificación y reutilización de modelos digitales 3D, así como en la gestión y comunicación del conocimiento técnico vinculado al diseño. La idea principal de esta investigación doctoral es establecer un método para representar y evaluar el conocimiento implícito de los ingenieros de diseño acerca de un modelo digital, así como la integración dinámica de dicho conocimiento en el propio modelo CAD, a través de anotaciones, con el objetivo de poder almacenar y comunicar eficientemente la mayor cantidad de información útil acerca del modelo, y reducir el tiempo y esfuerzo requeridos para su alteración y/o reutilización.Dorribo Camba, J.

Architecture design in global and model-centric software development

This doctoral dissertation describes a series of empirical investigations into representation, dissemination and coordination of software architecture design in the context of global software development. A particular focus is placed on model-centric and model-driven software development.LEI Universiteit LeidenAlgorithms and the Foundations of Software technolog
