In the context of business process modeling, the transformation of process information elicited from process participants into process models often remains a black box. This paper presents a method that supports the designer to extract a formal business process model from natural language captured in written form in a transparent and traceable way. To-do’s of process participants are examined b...

STAIRS is an approach to the compositional development of sequence diagrams supporting the specification of mandatory as well as potential behavior. In order to express the necessary distinction between black-box and glass-box refinement, an extension of the semantic framework with three event messages is introduced. A concrete syntax is also proposed. The proposed extension is especially usefu...

In this paper, we present a system capable of improving the I/O performance in an automatic way. This system is able to learn the behavior of the applications running on top and find the best data placement in the disk in order to improve the I/O performance. This system is built by three independent modules. The first one is able to learn the behavior of a workload in order to be able to repro...

As a force that leads the era of rapid technology advances, integrating global economy and changing customer needs, enterprise agility has attracted extensive attention from academia. The purpose of this study is to take Haier information system (IS) development from China as a case study to systematically research the process, reasons and characteristics of IS-enabled enterprise agility based ...

When a student makes an error, the instructor wonders what possible misconception caused that error (Self, 1990) and attempts to correct it through altering the instruction method. Consequently, student models represent the system’s assumptions of learner knowledge and preferences without giving any guarantees that this model accurately reflects any of the information it contains. These models ...

The modelling of complex problems tends to be most effective when modelling is calibrated using a concrete solver and modifications to the model are made as a result. In some cases, the final model is significantly different from the simple model that best fits the constraints of the problem. While there are several projects that are attempting to create black box solvers with generic modelling...

In this paper, approaches to assess the reliability of the COTS software for a given or specified operation profile have been analyzed using the proposed methods for White box and Black box approaches. In the black box approach the fragile point analysis is used to assess the reliability of the software, for a given operational profile, using the functional or design specification of the software.

We deene a notion of equivalence for designs containing black boxes. Using this notion, we describe a sound and complete methodology for optimizing designs containing black boxes, i.e. components whose functionality is not known; these arise naturally in the course of hierarchical design.

A key aspect of the Object-Oriented (OO) approach is that a designer can enrich an OO system by providing suitable (re-)definitions for some of the methods of the given system. Application frameworks provide good examples of such enrichment. An OO framework typically provides a number of template methods that implement specific patterns of calls to hook methods. An application developer can cus...

The Shiraz project included an evaluation component: two ‘glass-box’ evaluations have been performed during the project as well as a black-box evaluation at the end of the project. The evaluations were based on the use of a bilingual tagged test corpus of 3000 sentences. Evaluation tools were developed in order to automate the evaluation process. The glass-box evaluations included the evaluatio...
