Current citation-based document retrieval systems generally offer only limited search facilities, such as author search. In order to facilitate more advanced search functions, we have developed a significantly improved system that employs two novel techniques: Context-based Cluster Analysis (CCA) and Context-based Ontology Generation frAmework (COGA). CCA aims to extract relevant information from clusters originally obtained from disparate clustering methods by building relationships between them. The built relationships are then represented as formal context using the Formal Concept Analysis (FCA) technique. COGA aims to generate ontology from clusters relationship built by CCA. By combining these two techniques, we are able to perform ontology learning from a citation database using clustering results. We have implemented the improved system and have demonstrated its use for finding research domain expertise. We have also conducted performance evaluation on the system and the results are encouraging. 相似文献

The creation of expert systems is one way in which knowledge is codified. In creating an expert system, in general there are three aspects to the codification process: creating a model of the knowledge to be codified; creating the language in which to express the model; and writing messages representing the knowledge in that language. These aspects have different relative importance in different contexts. Referring to four case studies, the paper argues further that codification through creating expert systems is not uniformly successful and part of the variation has to do with the nature of the knowledge, or intellectual process or activity being codified, and the difficulty in creating the model. Activities with fixed goals and linear processes lend themselves very well to this form of codification. Processes of categorization and analogy, such as fault detection and repair, are partially successful, tending more often to create systems for experts. Processes involving balancing conflicting goals have, to date, tended to be unsuccessfully codified. These process types involve knowledge or understanding at deeper and deeper levels of abstraction of the overall processes and overarching goals. The more abstract and less concrete the knowledge involved in the task, the more difficult it is to codify it. 相似文献

Publication and patent behavior of academic researchers: Conflicting, reinforcing or merely co-existing? 总被引:1,自引:0,他引:1
Increasing entrepreneurial activity within academia has raised concerns that the number of publications added to the scientific commons might be reduced or that academic research would be directed exclusively towards the application-oriented needs of industry. In the case of academic inventions, the potential conflict between public- and private-oriented considerations seems most salient. In this contribution, we examine whether the publication behavior of academic inventors (at K.U. Leuven) differs from their colleagues (non-inventors) working within similar fields of research. Our analysis reveals that inventors publish significantly more. Moreover, no empirical evidence was found for the ‘skewing problem’. These findings not only suggest the co-existence of both activities; they may actually reinforce each other. 相似文献

In this article, the author argues that the exploration of alternative forms of research representation can result in new possibilities for making meaning in educational research. Narrative inquiry as a methodology has become established as an approach in education but remains contested in many ways. How we come to an understanding of such research findings and in particular how the issues of voice and representation are resolved are subject to much debate. Here, the author proposes that using fictive methods of representation of research, particularly poetry, can have implications for the ways in which meaning is made and therefore the possible meanings that can be made. Further, this article argues that the poetic form allows for the inclusion of many voices and stories in a non-hierarchical manner, making the author's influence explicit without it being dominant. Researchers have argued for poetic representations of research data as a means to evoke the participants' experience whilst making the author's influence explicit; here, it is argued that poetry can be utilized to provide a fuller representation of the research, placing the voice of the participants, the researcher and the literature on an equal level within the whole story of the research project. This article first details narrative inquiry as a methodological approach and its particular application to educational research before discussing the issues surrounding voice and representation. Subsequently, fictive forms of representation are explored as a means of addressing these issues. 相似文献
