The traditional trustworthiness evaluation of running software is inaccurate and incomplete because each component is as an independent unit during reliability evaluation. According to the drawbacks of traditional models, this paper proposed a trustworthiness evaluation approach of component-based software based on level. The trustworthy behavior trace diagram of componentbased software was pre...

Component evaluation and acceptance testing is considered as a critical task comprising: analysis of condition and constrains (result: evaluation requirements), specification of the evaluation (result: identification of relevant component items and associated component attributes), design of the evaluation (result: evaluation plan), conducting the evaluation (result: test and measurement report...

The architecture of a software system is crucial since it often affects and limits the quality attributes of the system, e.g., performance and maintainability. In this paper we evaluate three communication components suggested for use in a software architecture using prototype-based evaluation. We evaluate the performance quantitatively, and also present qualitative results on portability and m...

Distributed object models form the basis for distributed component-based applications. This paper is focused on qualitative and quantitative analysis of two most important distributed object models for use with the Java programming language: CORBA and RMI. We compare both models in terms of features, maturity, legacy system support and ease of development. Special attention is paid to performan...

Component-based development (CBD) has received a lot of attention in software engineering literature over the last few years. Awareness has been raised that CBD is the way to go in software development, especially in the domain of e-business where the benefits of reusing components, i.e., faster time-to-market and quality, are essential. The question now is how to realize the full potential of ...

Automatic question answering (QA) is a complex task, which lies in the cross-road of Natural Language Processing, Information Retrieval and Human Computer Interaction. A typical QA system has four modules – question processing, document retrieval, answer extraction and answer presentation. In each of these modules, a multitude of tools can be used. Therefore, the performance evaluation of each ...
