本体在产品知识表达中的应用研究

随着全球化竞争的日趋激烈,当代企业必须更加灵活、有效地生产用户所需的产品,而在产品设计中,缺乏对产品功能设计的描述,这就限制了产品的知识表达、传播、共享。文中从产品知识表达存在的问题出发,提出了基于本体的产品知识表达四层模型,即结构层—行为层—基本功能层—元功能层,给出了各层本体的表示模式。最后以洗衣机为例,给出它在四层模型中的表示和OWL描述。结果证明把本体引入产品知识表达中是合理的,四层模型中各层知识表达模式的相互补充,更加完善了产品的知识表达。

Design and validation of a knowledge map system—the case of construction industry in Taiwan

Knowledge map systems (KMSs) have recently received widespread attention. A review of the literature shows that relatively few studies explicitly address the issues of implementation and user evaluation of the system and are limited in application. In view of this dilemma, this study aims to integrate the key features of knowledge assets maps, knowledge sources maps, knowledge structure maps, and knowledge task maps in order to develop an operational KMS. Also, the technology acceptance model was used as the theoretical basis for the assessment of user acceptance of the system, which is validated using structural equation modeling. In terms of user acceptance assessment, our empirical results shows that the perceived usefulness and perceived ease of use will positively affect user attitude toward the proposed KMS. Also, our results suggest that social defense negatively moderates the effect of attitude toward the system on behavior intention. Furthermore, we found that the management system also positively moderates the effect of attitude toward the system on behavior intention. On the basis of theoretical evaluation and empirical investigation, we hope that the proposed construction of a knowledge system can serve as references for both academic and related practical fields.     

Measuring user satisfaction with knowledge management systems: scale development,purification, and initial test

The shift from a product-based to a knowledge-based economy has resulted in an increased demand for knowledge workers who are capable of higher-order thinking and reasoning to solve intricate problems in the workplace. This requires organizations to introduce knowledge management systems (KMS) for employees and has fueled predictions and speculations about what makes KMS effective. Unfortunately, there are very few empirical studies that examine this issue. Thus, this paper develops a validated instrument to measure user satisfaction as a surrogate measure of KMS effectiveness. Based on a survey of 147 respondents practicing mostly in four international semiconductor manufacturing companies in the Hsin-Chu Science-based Industrial Park in Taiwan suggests a 16-item instrument that measures four dimensions of user satisfaction with knowledge management systems (USKMS) is well-validated. The instrument and comprehensive model proposed in this paper would be valuable to researchers and practitioners interested in designing, implementing, and managing knowledge management systems.

What drives continued knowledge sharing? An investigation of knowledge-contribution and -seeking beliefs

Knowledge management (KM) research has yielded extensive explanations regarding the individual's motivation to share knowledge, each with different sets of factors. Yet the study of continued knowledge sharing is rare. There has been little research investigating this issue from contributing and seeking perspectives—the two distinct, but closely interrelated, facets of continued knowledge sharing. We propose that knowledge management system (KMS) users' beliefs are contextually differentiated, and thus a distinction between knowledge-contribution and knowledge-seeking behaviors and an adequate emphasis on their variance in terms of user belief is needed. By incorporating the knowledge-contribution and knowledge-seeking perspectives in a single study, we model and examine the differences among driving factors in two behavioral contexts, provide the conceptual comparisons and preliminary discussions, and thus advance our understanding of continued knowledge sharing via the KMS.     

Effects of information technologies,department characteristics and individual roles on improving knowledge sharing visibility: a qualitative case study

Knowledge sharing visibility (KSV) is a critical environmental factor which can reduce social loafing in knowledge sharing (KS). This is especially true in ICT-based KS in learning organisations. As such, it is imperative that we better understand how to design technology enabled knowledge management systems (KMS) to support high KSV. This article examines the impact of knowledge management technology functions (e.g. tracking, knowledge storing) on KSV through qualitative analysis of 16 semi-structured interviews with participants in a Chinese company. Impact and implications of use for their existing KMS are examined. This article also examined the effects of department characteristics (i.e. group size and task characteristics) and individual roles (i.e. employee positions) on the IT–KSV relationship. Results encourage applied statistical, tracking, knowledge distribution and knowledge storing functions for monitoring explicit KS, and suggest integration of visualised knowledge maps with communication tools (e.g. Instant Messenger (IM)) to support visibility for implicit KS. Findings also suggest that KM technologies are more salient on improving KSV in large department with routine tasks, and that low-level employees may have more positive attitude on accepting communication tools on sharing knowledge. Extension to use of Web 2.0 technologies (e.g. weblogs) in KMS is also explored.
