动态竞争情报是企业在复杂多变的竞争环境中取得成功的关键.针对传统的竞争情报分析模型无法有效地对信息资源进行深层次的多维分析,获取语义层面的动态竞争情报,本文构建了基于联机分析挖掘的动态竞争情报多维语义分析模型.该模型利用竞争情报领域本体指导目标信息的采集与监控和实体与关系的抽取,实现竞争情报的语义组织和存储;设计了一种基于语义的多维关联分析算法进行语义层面的数据挖掘、学习和推理,实现竞争情报多维语义挖掘和知识发现.实验结果表明,该模型取得了很好的预期效果,显著提高了情报分析的深度与广度和情报分析的准确率与效率. 相似文献

文章在对产业竞争情报和产业链理论讨论的基础上,明确了产业链理论用于产业竞争情报分析的重要意义。从产业链角度出发,提出产业链主导范式下的产业竞争情报分析框架,即由宏观经济、金融市场、产业政策、政治法律构成的产业链外部情报,以及产业链中的企业和产品服务、供需信息、技术信息构成的产业链内部情报,阐述了其在产业链中的流动机制,并提出了相应的分析方法。 相似文献

Twitter has become a global, social media platform that is reshaping the way journalists communicate, gather information, and disseminate news. This study builds on the relatively young field of research by using diffusion of innovation theory to gauge what factors influence the spread and adoption of Twitter. Case-study and in-depth interview methods were used in collecting data from 50 journalists at 4 metropolitan newspapers. Results show that the adoption and implementation of Twitter relies on peer pressure and coaching to get reluctant journalists to try Twitter. Adoption is then immediate because journalists see how Twitter is a gateway to new sources of information and story tips. Ultimately, journalists embrace Twitter because it provides instant gratification from followers, allowing them to share stories with a broader, global audience. 相似文献

Anthropologists at seven universities were surveyed in order to discover: the ways in which they go about locating information of value to them; the information sources that they use and that are of the greatest significance to them; the adequacy of the library service being currently provided to anthropologists; and any opinions they have on the subject of their information needs. Results show that anthropologists; information requirements differ somewhat from those of other social scientists. Reference lists in journals and books are often used to locate information sources; journals are the most important information source. However, cultural anthropologists report that their own field data is their most significant source. Anthropologists use pictorial sources and maps more frequently than social scientists in general do; they also make great use of interlibrary loan. Most of the information needs of the majority of respondents are met by their university's library. Older scholars tend to use databases less than younger ones do; online abstracts and indexes are most important to anthropologists than their print versions are. Some respondents express a great desire for a database which would include current references, abstracts, and articles in anthropology. 相似文献

This article analyses the professional interactions between female journalists and their sources, key moments in the information production process, and explores, in the context of the Swiss daily press, one of the most masculine journalistic universes: sports journalism. It illustrates that because of the specific mode of recruitment into this journalistic speciality, women are confronted with various constraints—a lack of knowledge in the domain of sports, overwhelmingly male sources, and tensions linked to the fact that they are women—and with expectations from their chief editors that they will develop a “feminine” view of sports news. They are required to adapt and adjust to their role in a way that severely constrains their interactions with their male sources. Thus, controlling their appearance, language, and attitudes, these women make intentional use of certain stereotypes associated with femininity—“women as object of seduction” and “women as weak and inoffensive”—for professional goals, when the interaction warrants. They believe that those strategies allow them to have easier access to their sources and to create interactions encouraging the exchange of information that they judge to be sincere, authentic and more private, that would permit them to write deeper and more “human” articles. 相似文献

Dentists, as health professionals, need access to information. As in other health sciences, the increase in the rate and volume of published information has made it more difficult for them to keep up with new developments. Five hundred randomly selected dentists in Louisiana were surveyed to determine what information dentists seek and what sources they prefer. Responses indicated that dentists need information on new techniques in dentistry and that preferred sources are professional colleagues and personal journal collections. Libraries were found to be used only infrequently as sources for information. Implications for planning libraries for applications- and technique-oriented professions are discussed. 相似文献

Geographic information sources have evolved at the same rate as the many other information sources in the last half a century. This article discusses geographic literacy and spatial thinking, and the questions that derive from geographic inquiry. Librarians in academic libraries are most often called on to meet the complex specialized geographic information needs that arise from study and practice in those areas. The sources we use and the ways we respond to these needs have evolved and expanded with the advent of various digital technologies. In order to be able to work with these new technologies, librarians can develop specialized competencies in geographic information systems (GIS) which allow them to go beyond print maps and atlases in the provision of geographic information. 相似文献

ABSTRACTAs information sources have expanded, there have been parallel changes in the way students and researchers find and use that information. The role of the library has shifted to embedding information literacy skills into the curriculum as a primary function. This presentation explored how librarians are becoming more involved with information literacy curriculum and how publishers can assist them, particularly regarding access to information and the scholarly publishing process. Since 2015, Rebecca Donlan at Florida Gulf Coast University (FGCU) and Stacy Stanislaw at Taylor & Francis Group have been collaborating on an information literacy program for FGCU students and faculty that focuses specifically on navigating the scholarly publishing landscape. Donlan and Stanislaw provided an overview of the project, its formation, implementation, and progress to date. 相似文献

This paper attempts to make a comparison between a western culture, Canada, and an eastern culture, China, in the use of business information. As part of a larger project of measuring the impact of information on development, four surveys of the business communities in these two countries were conducted. Two of them were carried out in Shanghai, China, with one aimed at small business and the other at medium-sized business. The other two were conducted in Canada with the same coverage as the corresponding surveys in China. Data were collected on the use of various types of information sources in business operations. Results show that informal information sources are more important and better used than the formal ones in both cultures. However, business people's self-perception of their information use differs between the two cultures. Electronic information sources are currently poorly used in both countries. 相似文献
