实体关系抽取的技术方法综述*   总被引:3,自引:0,他引:3  
对实体关系抽取研究以MUC和ACE评测为主线的发展进行总结,并指出实体关系抽取任务普遍存在的三个问题是特定领域标引数据集的获取、模式的获取以及共指消解。在对当前关系抽取的相关文献、系统和项目进行分析研究的基础上,将基于非结构化文本的实体关系抽取技术方法归纳为:基于模式匹配的关系抽取、基于词典驱动的关系抽取、基于机器学习的关系抽取、基于Ontology的关系抽取以及混合抽取方法,旨在为进一步构建实体关系抽取系统提供良好借鉴。  相似文献

This article chronicles the rapid expansion since 1990 of research within archival science and characterizes contemporary archival research culture. It examines the role and state of key factors that have led to the development of the existing research infrastructure, such as growth in doctoral education, forums for presenting and publishing research, the numbers and size of graduate archival education programs, availability of diverse funding for research, transdisciplinary and international research collaborations, and application of innovative research methods and tools appropriate for investigating increasingly complex and wide-ranging research questions. An Appendix articulates and names archival research methods, including those derived and adapted from other disciplines, with a view to adding to the “literary warrant” for archival research methods, promoting the rigorous application of research design and methods, and providing sources for the teaching of research methods for professional and research careers. The article concludes with recommendations about how to sustain and extend the emerging research front.  相似文献

ABSTRACT

In this article, I question practice as a research paradigm by exploring its position in relation to non-positivist qualitative methodologies. Frayling’s [1994. Research in art and design. Royal College of Art Research Papers, 1(1), 1993/4] distinctions between research into, through, and as (for) practice are expanded to explore overlaps between these approaches. I argue for the need to understand the nuances of different epistemologies and ontologies that underpin diverse disciplinary approaches to practice-research. This is done through an analysis of a selection of Arts and Humanities Research Council (AHRC)-funded projects to find out how they are using and/or embedding practice in the research process. The resulting Colour Wheel of Practice-Research illustrates a spectrum of positions of practice in relation to research, suggesting existing research paradigms are bursting at the seams and that the “disciplinary matrix” of practice might offers other ways of knowing. The reason I have chosen to focus primarily on AHRC-funded projects is because it explicitly states its support of “practice-led research” and that it “remains dedicated to this area of research”. This article aims to add to knowledge of how and why practice-research is of continuing interest to research councils, universities, and those identifying as practice-based/led researchers.  相似文献

This mixed-methods study examined the experiences of belonging/otherness among Arab teachers in Israel. A group of boundary-crossing teachers: Arab teachers in Jewish schools (AJ; N = 57) was compared with Arab teachers teaching in their own community (AA; N = 103). We found that the AJ group had a multicultural orientation, unlike the AA group, who were community-orientated. These orientations are reflected in different otherness sources, different motivations for selecting a workplace, and differences in identity ratings. While professional and social sources promoted teachers’ sense of belonging in the two groups, the source of AJs' sense of otherness was the national divide as opposed to community-oriented aspects in AAs. Selfefficacy ratings were high in both groups with a significant advantage for AJs, an unanticipated finding given that most of them were women, had attended teacher training colleges rather than universities, and were rarely homeroom teachers. Arab teachers' involvement in Jewish schools was partial with a low proportion of classroom educators or teachers in managerial roles. AJs tend to leave their national identity outside the school, and are not involved in political discourse or in the staffroom power relations. The phenomenon of integrating AJs is relatively new, and within a segregated education system that limits the opportunities for Jews and Arabs to meet, it can provide a viable, albeit limited, tool to inhibit prejudice and antagonism between Jews and Arabs.  相似文献
