Performance assessment of intelligent distributed systems through software performance ontology engineering (SPOE)

In the computer science community there is a growing interest in the field of Ambient Intelligent Systems. This systems surround their human users with computing and networking technology unobtrusively embedded in their environment. This technology is aimed to provide the users with useful information and to take action to make the environment more convenient for them. As the number of users increases the resources that make Ambient Intelligence possible can be easily saturated making the system unstable and projecting an image of poor QoS to the users. The main goal of this paper is to provide the means for the Ambient Intelligent Systems to monitor themselves and take corrective action automatically if performance starts to drop. Our approach uses a Performance Ontology that structures the knowledge about Software Performance Engineering, and a reasoning engine that acts like an expert system with the Performance Ontology as its foundation. The case study at the end shows the applicability of the developed techniques.     

Towards a Machine of a Process (MOP) ontology to facilitate e-commerce of industrial machinery

Adapting to user's requirements is a key factor for enterprise success. Despite the existence of several approaches that point in this direction, simplifying integration and interoperability among users, suppliers and the enterprise during product lifecycle, is still an open issue. Ontologies have been used in some manufacturing applications and they promise to be a valid approach to model manufacturing resources of enterprises (e.g. machinery and raw material). Nevertheless, in this domain, most of the ontologies have been developed following methodologies based on development from scratch, thus ontologies previously developed have been discarded. Such ontological methodologies tend to hold the interoperability issues in some level. In this paper, a method that integrates ontology reuse with ontology validation and learning is presented. An upper (top-level) ontology for manufacturing was used as a reference to evaluate and to improve specific domain ontology. The evaluation procedure was based on the systemic methodology for ontology learning (SMOL). As a result of the application of SMOL, an ontology entitled Machine of a Process (MOP) was developed. The terminology included in MOP was validated by means of a text mining procedure called Term Frequency–Inverse Document Frequency (TF–IDF) which was carried out on documents from the domain in this study. Competency questions were performed on preexisting domain ontologies and MOP, proving that this new ontology has a performance better than the domain ontologies used as seed.     

An ontology for the harmonization of multiple standards and models

Harmonization plays an important role in organizations that are seeking to resolve manifold needs at their different hierarchical levels through multiple models such as CMMI, ISO 90003, ITIL, SWEBOK, COBIT, amongst others. A great diversity of models involves a wide heterogeneity not only about structure of their process entities and quality systems, but also with regards to terminology. This article presents an ontology which: provides the main concepts related to harmonization of multiple models; is supported by a web tool and; has been applied for the harmonization of COBIT 4.1, Basel II, VAL IT, RISK IT, ISO 27002 and ITIL.

Developing taxonomy for the domain ontology of construction contractual semantics: A case study on the AIA A201 document

In construction contractual management, sharing experts’ domain knowledge through ontology is a good way to narrow the knowledge gap between the domain experts and the construction team. However, little work has been done on ontology taxonomy development in this domain. Based on a literature review on sharing domain knowledge, taxonomy development methods and the essence of construction contracts, this study proposes a synthesized methodology for taxonomy development in the domain of construction contractual semantics. This methodology is based on an ontological model extracted from definitions found in the contract, and uses common root concepts as the initial root concept classes, and includes the iterative development and competency questions approaches as well. In the case study, using the research results from pilot studies, the proposed methodology was applied to the AIA A201 General Conditions of the Contract for Construction (2007) document at the textual level. As a result, a taxonomy was developed which was used to determine the validity of the proposed methodology. The taxonomy development methodology and the developed taxonomy itself are both valuable contributions in the quest to further develop ontology-based applications for sharing domain knowledge about construction contract semantics.     

Pellet本体概念分类算法优化

针对Pellet1.4(简称Pellet)推理机的本体概念分类算法效率较低,为了通过减少调用ABOX推理概念间包含关系来提高分类性能,提出了一种全局标记方法.方法首先对所有节点嵌入一个二维散列mark,用于节点存储与其他节点的包含关系标记.然后在推理过程中通过ABOX的推理结果.动态修改相关节点中mark的标记信息.最后充分利用以前的推理结果所修改的标记信息来减少ABOX一致性检测次数.通过使用全局标记方法的算法替代Pellet推理机中原有概念分类算法对实际本体分类进行仿真,实验结果表明该方法可以有效地减少调用ABOX执行一致性检测次数,提高本体概念分类性能.

International Migration for Work-Consequences for the Families Who Remain at Home (The Case of Romania)

This paper analyses the consequences of international migration for work on families who remain at home in a Romanian rural sample. Five types of effects were identified: financial; on spousal relations; on children; on old family members and on composition of the population. The most important are the financial impacts, but there are also invisible side-effects, such as deterioration in the relations between spouses and the decrease of the parents?? roles for children. The importance of the old family members is re-evaluated; they are key social links between migrants and the family members that have remained at home.
