This paper presents an approach aimed at creating business ontologies for knowledge codification in company. It is based on the principles of ontological engineering and cognitive psychology. Ontologies that describe the main concepts of knowledge are used both for knowledge creation and codification. The proposed framework is targeted at the development of methodologies that can scaffold the process of knowledge structuring and orchestrating for better understanding and knowledge sharing. The orchestrating procedure is the kernel of ontology development. The main stress is put on using visual techniques of mind mapping. Cognitive bias and some results of Gestalt psychology are highlighted as a general guideline. The ideas of balance, clarity, and beauty are applied to the ontology orchestrating procedures. The examples are taken mainly from the project management practice. The paper contributes to managerial practice by describing the practical recommendations for effective knowledge management based on ontology engineering and knowledge structuring techniques. 相似文献

近年来,参与实验作为STS中新出现的研究方法受到了广泛的关注。在方法层面,参与实验吸收了行动者-网络理论(ANT)等研究成果对实践的关注,挑战了现有公众参与科学模式囿于议程、代表权、共识等概念的困境,将公众参与科学引向对日常活动中物质实践的定制和分析。在理论层面,参与实验区分了ANT、存在论政治学等“经验化”存在论方案,试图在STS中建立一种“实验化”的存在论方案。“实验化”研究突破了“经验化”研究的方法论框架,但其存在论地位仍显模糊。本研究讨论了德勒兹与拉图尔对伦理问题的不同思考,指出了两者在伦理学上不同的存在论立场可以成为解释“实验化”和“经验化”之间对立根源的思想线索。在此思想线索的基础上,诉诸“遭遇中的生成”将为“实验化”存在论方案提供一条区分于“经验化”的立足之途,从而为在“公众参与科学”中促发更多具备可行性的实践方案提供一种可能的理论前提。 相似文献

This paper examines the meaning of context in relation to ontology based query expansion and contains a review of query expansion approaches. The various query expansion approaches include relevance feedback, corpus dependent knowledge models and corpus independent knowledge models. Case studies detailing query expansion using domain-specific and domain-independent ontologies are also included. The penultimate section attempts to synthesise the information obtained from the review and provide success factors in using an ontology for query expansion. Finally the area of further research in applying context from an ontology to query expansion within a newswire domain is described. 相似文献

In this paper we outline an approach to application of ontology in knowledge management. The University of Belgrade Faculty of Mining and Geology research team has developed a terminological resource to support knowledge management in mining engineering. Mining engineering, like all other engineering disciplines, needs comprehensive, consistent and standardized definitions of terms for efficient knowledge management and interoperability among various related IT applications. This goal can best be reached by terminological resources in electronic form organized as thesauruses or ontologies. The resource used to illustrate this approach, RudOnto, is a system of ontologies developed for mining engineering and their application in mining equipment and mine safety domains. Key benefits of applying ontologies in knowledge management, aside from securing interoperability, are enhancement of browsing/searching functions, and reuse and structuring capabilities. Through export to several specific formats, RudOnto ontologies offer the possibility of generating stand-alone terminological resources or ontologies in specific sub-fields, such as mining equipment, mine safety and geostatistics. 相似文献

This article presents conceptual navigation and NavCon, an architecture that implements this navigation in World Wide Web pages. NavCon architecture makes use of ontology as metadata to contextualize user search for information. Based on ontologies, NavCon automatically inserts conceptual links in Web pages. By using these links, the user may navigate in a graph representing ontology concepts and their relationships. By browsing this graph, it is possible to reach documents associated with the user desired ontology concept. This Web navigation supported by ontology concepts we call conceptual navigation. Conceptual navigation is a technique to browse Web sites within a context. The context filters relevant retrieved information. The context also drives user navigation through paths that meet his needs. A company may implement conceptual navigation to improve user search for information in a knowledge management environment. We suggest that the use of an ontology to conduct navigation in an Intranet may help the user to have a better understanding about the knowledge structure of the company. 相似文献

语义Web的创建需要一套共同的标准概念体系,即本体(Ontology)。本体的构造手段仍然是以手工构造为主,效率和准确率都非常低,很容易导致知识获取的瓶颈。本文给出一个半自动化的需人工干预的本体学习体系结构,采用平衡的协作建模方式来构造语义Web中的本体;介绍了基于以上体系结构的本体学习的处理过程,并讨论了领域概念抽取,概念之间关系的抽取等关键技术。 相似文献

基于本体的战场信息表示研究 总被引:2,自引:0,他引:2
根据未来信息化战争的实际,本文提出了如何用本体对战场信息进行表示。主要从建立战场信息的本体结构及其属性类,确立基于本体的战场信息表示规则以及其描述语言的文法等方面进行战场信息的本体化表示研究。本文首次提出战场信息本体的体系结构和战场信息本体的属性类。对战场信息进行本体化表示进行研究尚属首次,许多工作还处在探讨中,从理论上看它不但可消除战场上的信息孤岛,而且为实现不同指挥控制系统间的互联互通,创造了十分便利的条件。 相似文献

Mainstream social media, such as Facebook, Twitter, and Weibo, provide enterprises an opportunity to innovate and develop. User-generated content on social media platforms can help determine the needs of the user and identify a target market, providing a basis for enterprise innovation. In this study, we propose a user-interactive innovation knowledge acquisition model. Accordingly, the comments data on a selected forum were first crawled using network crawler software. Subsequently, we pre-processed the data to obtain a semi-structured user corpus. We then used the Latent Dirichlet Allocation model to cluster topics and obtain the subject words that were hidden from each comment text. A user demand ontology was built based on the subject words, and with an expert's reference, the product function ontology was established. Through semantic similarity matching, we integrated two ontologies to obtain the user-interactive innovation knowledge acquisition model. Finally, the model was validated using the Volvo XC60 automobile as an example. The empirical results showed that the proposed model could assist enterprises by providing ideas for follow-up innovation and product development. 相似文献

论知识的存在论化及其问题-以个人知识的视角 《科学学研究》2017,35(10):1441-1446
目前,多数科学的实践论者主张,对知识的考察不应囿于认识论,而应将其扩张至存在论。由此,劳斯意义上的“地方性知识”引发了广泛的讨论。其中,拉图尔的观点最为激进,主张将知识存在论化,否定认识论的独立地位,以此破除主体性及传统二元论。然而,这种主张的问题也很尖锐:作为有意识的行动者的人的自主性是其他非人行动者并不具有的。而拉图尔却用赋予一切行动者能动性来消除这种本质差异只是在规避问题。早于拉图尔,同为科学的实践论者的波兰尼提出并论证了知识的默会根源,阐明了知识与人自身的内在关联,将作为表象着的主体的人与作为实践着的行动者的人很好地统一起来,实现了同时在认识论和存在论中对知识的考察与讨论,为我们提供了一条反思和批判知识存在论化的理路。 相似文献

The amount of heterogeneous data that is available to organizations nowadays has made information management a seriously complicated task, yet crucial since this data can be a valuable asset for business intelligence. Ontologies can act as a semantically rich knowledge base in systems that specialize in information management. The present work investigates the potential of ontologies in supporting the information lifecycle within a corporate environment for business intelligence. The paper demonstrates the use of Heraclitus II, a framework that employs ontology management and evolution in the context of information management systems. The capabilities of the framework in facilitating information management and business intelligence are evaluated through a real-life case study from the life sciences industry. 相似文献
