信息资源管理研究的多重视角及其共同体的形成(Ⅱ)——企业领域及情报学视野下的研究          下载免费PDF全文

宋恩梅 《中国图书馆学报》2007,33(6)

企业领域的信息资源管理发展是以信息技术为主线,表现出明显的技术导向。从发展趋势看,它将由IT管理转向以信息内容为导向的管理。情报学对信息资源管理的研究很大程度上沿袭了情报管理的思想,具有多重研究领域。这两个领域的IRM研究在研究模式、定位、领域、成果刊发、人员培训等方面,都存在差异。表1。图2。参考文献20。  相似文献

Field independent probabilistic model for clustering multi-field documents     

Shanfeng Zhu  Ichigaku Takigawa  Jia Zeng  Hiroshi Mamitsuka   《Information processing & management》2009,45(5):555-570

We propose a new finite mixture model for clustering multiple-field documents, such as scientific literature with distinct fields: title, abstract, keywords, main text and references. This probabilistic model, which we call field independent clustering model (FICM), incorporates the distinct word distributions of each field to integrate the discriminative abilities of each field as well as to select the most suitable component probabilistic model for each field. We evaluated the performance of FICM by applying it to the problem of clustering three-field (title, abstract and MeSH) biomedical documents from TREC 2004 and 2005 Genomics tracks, and two-field (title and abstract) news reports from Reuters-21578. Experimental results showed that FICM outperformed the classical multinomial model and the multivariate Bernoulli model, being at a statistically significant level for all the three collections. These results indicate that FICM outperformed widely-used probabilistic models for document clustering by considering the characteristics of each field. We further showed that the component model, which is consistent with the nature of the corresponding field, achieved a better performance and considering the diversity of model setting also gave a further performance improvement. An extended abstract of parts of the work presented in this paper has appeared in Zhu et al. [Zhu, S., Takigawa, I., Zhang, S., & Mamitsuka, H. (2007).

Collaborative information seeking: A field study of a multidisciplinary patient care team     

Madhu C. Reddy  Patricia Ruma SpenceAuthor Vitae 《Information processing & management》2008

Multidisciplinary teams are an essential aspect of modern organizational work. These teams often work in information-rich environments but little is known about their collaborative information seeking (CIS) behavior. We have been studying the CIS behavior of teams in the context of medical care. We conducted an ethnographic field study of a multidisciplinary patient care team in an emergency department to identify (a) team information needs and (b) situations that trigger collaborative information seeking activities. We identified seven categories of information needs as expressed by questions asked by team members. The majority of questions focused on medical information, but there were a larger than expected percentage of questions focusing on organizational information. We also identified three triggers for CIS activities. These triggers are: (1) lack of expertise, (2) lack of immediately accessible information, and (3) complex information needs. The questions and triggers highlight the importance of face-to-face communication during CIS activities and how CIS activities could lead to interruptive workplaces. We also discuss organizational and technical implications for supporting CIS behavior of teams.  相似文献   

Socio-cultural framing during the emergence of a technological field: Creating cultural resonance for solar technology     

《Research Policy》2019,48(9):103830

This paper depicts how cultural resonance for novel technologies is constructed as a gradual, interactive process. We adopt a cultural framing perspective and strive to understand how actors assign meaning to the novel technology and determine its appropriateness for the local context. Existing research has largely focused on the strategic and political aspects of field framing processes through depicting conscious framing struggles between protagonist and antagonist actors. In addition to such strategic framing activities, we examine how other socio-cultural factors, such as changes in actor positions, interaction between framing activities, and the cultural “repertoire” of frames interact in producing cultural resonance. For our empirical case study, we followed the emerging technological field of solar energy during an intensive period of change. Our study contributes to the growing number of studies that draw attention to the creation of cultural resonance as an interactive multi-actor process by offering in-depth understanding of the multifaceted interactions that constitute the meaning-making process for an emerging field.  相似文献
