This study examined the Twitter streams and websites of 36 university innovation centers and identified 14 service categories the centers offered. Exploring the present Twitter use practices of innovation centers and the services the centers provide can inform the design and planning of service offerings at new innovation centers and support training for center staff in the use of this social media platform. In addition, existing innovation centers can benchmark their service offerings against those services. Furthermore, mapping the services the innovation centers offer to the activities in an innovation workflow model can help center managers optimize the information architecture of their websites and resource guides. In this way, students can easily be informed about the help and resources available for each activity or phase of the innovation process. A comparison of the tweet categories identified in the present study with those of academic libraries assembled in a previous study revealed significant overlap, but some differences as well. In contrast to the Twitter accounts of academic libraries, the Twitter accounts of innovation centers did not tweet about their information services even if they offered them. Innovation centers also did not use Twitter to provide Q&A services to their users. Furthermore, innovation centers tweeted not only about the technological resources they provided, but also about the human resources they recruited to serve as student mentors and advisors. Finally, technology use was more mediated in innovation centers than in libraries, and some centers offered their users fee-based assistance from professionals with their 3D design and printing tasks. 相似文献

This study examined factors that might affect researchers' willingness to collaborate with a specific researcher and the priorities given to those factors. In addition, it investigated how researchers determined the ownership of collaborative project data and how they determined the order of authorship on collaborative publications in condensed matter physics. In general, researchers rated their intrinsic motivations the highest, such as the quality of ideas a potential collaborator might have and their satisfaction with a past collaboration, followed by their extrinsic motivations, such as the complementary knowledge, skills, or resources the collaborator could provide. In addition, researchers who had a greater number of collaborative projects and researchers who had served as a project PI or co-PI valued the deep-level, personality-related characteristics of a collaborator higher than did those who had not. Younger researchers were more risk averse and more concerned with a collaborator's reputation and the possible cost of a collaboration decision. Additionally, younger researchers indicated more often than older researchers that they did not know whether their project teams followed any rules or norms or engaged in negotiation to determine the order of authorship on collaborative publications. 相似文献

As the amount of research data management is growing, the use of identity metadata for discovering, linking, and citing research data is growing too. To support the awareness of different identifier systems and the comparison and selection of an identifier for a particular data management environment, there is need for a knowledge base. This article contributes to that goal and analyzes the data management and related literatures to develop a data identifier taxonomy. The taxonomy includes four categories (domain, entity types, activities, and quality dimensions). In addition, the article describes 14 identifiers referenced in the literature and analyzes them along the taxonomy. 相似文献

Consumer health information-seeking behavior of members of a local Korean community in Tallahassee, Florida, was explored through semi-structured interviews. Questions explored how this community assessed the quality of health information, and what cultural values influenced their understanding of its quality. Accuracy and reliability were identified as the two most valuable quality characteristics. A commercial type of webpage was considered as a negative indicator for reliability, while information described in detail or displayed reiteratively was a positive indicator. In addition to functional quality criteria, nonfunctional characteristics such as sympathy were found. Above all, findings highlighted that cultural differences limited the use of health information. Quality based selection of information is an important part of a health information seeking process. Findings can give the designers of Web-based consumer health information systems important insights into how to support evaluation of the quality of health information by consumers, and how to reduce barriers to health information seeking and use caused by cultural differences. 相似文献

In the second half of the 20th century, scientific research in physics, chemistry, and engineering began to focus on the use of large government-funded laboratories. This shift toward so-called big science also brought about a concomitant change in scientific work itself, with a sustained trend toward the use of highly specialized scientific teams, elevating the role of team characteristics on scientific outputs. The actual impact of scientific knowledge is commonly measured by how often peer-reviewed publications are, in turn, cited by other researchers. Therefore, how characteristics such as author team seniority, affiliation diversity, and size affect the overall impact of team publications was examined. Citation information and author demographics were reviewed for 123 articles published in Physical Review Letters from 2004 to 2006 and written by 476 scientists who used the National High Magnetic Field Laboratory's facilities. Correlation analysis indicated that author teams that were more multi-institutional and had homogeneous seniority tended to have more senior scientists. In addition, the analysis suggests that more mixed seniority author teams were likely to be less institutionally dispersed. Quantile regression was used to examine the relationships between author-team characteristics and publication impact. The analysis indicated that both weighted average seniority and average seniority had a negative relationship with the number of citations the publication received. Furthermore, the analysis also showed a positive relationship between first-author seniority and the number of citations, and a negative relationship between the number of authors and the number of citations. 相似文献

Academic libraries can effectively plan and market their services by identifying the value users perceive in their services and in their social media communications about those services. This study reports on findings of a survey of 104 undergraduate students in information technology courses at a large research university. Results of an ordered logistic regression analysis indicated that students considered access to information and computer resources and study support services as the most important library services offered. Likewise, students perceived library social media postings related to operations updates, study support services, and events as the most useful. Future related research will investigate the needs and priorities for library services of other key user populations of academic libraries, such as graduate students and online students, to assemble service repertoires that are tailored to individual user groups. In addition, future research will examine whether and how libraries can use the analysis of users' engagement with a library's social media postings to inexpensively gauge the value they perceive in library services. 相似文献

An initial exploration into the issue of information quality evaluation across different cultural and community contexts based on data collected from the Arabic, English, and Korean Wikipedias showed that different Wikipedia communities may have different understandings of and models for quality. It also showed the feasibility of using some article edit-based metrics for automated quality measurement across different Wikipedia contexts. A model for measuring context similarity was developed and used to evaluate the relationship between similarities in sociocultural factors and the understanding of information quality by the three Wikipedia communities. 相似文献

There have been ample suggestions in the literature that terms added to documents from Flickr and Wikipedia can complement traditional methods of indexing and controlled vocabularies. At the same time, adding new metadata to existing metadata objects may not always add value to those objects. The potential added-value of using user-contributed (“social”) terms from Flickr and the English Wikipedia in image indexing is compared with using two expert-created controlled vocabularies—the Thesaurus for Graphic Materials and the Library of Congress Subject Headings—without those social terms. Experiments confirmed that the social terms did add value, relative to terms from the controlled vocabularies. The median rating for the usefulness of social terms was significantly higher than the baseline rating, but was lower than the ratings for the terms from the Thesaurus for Graphic Materials and the Library of Congress Subject Headings. Furthermore, complementing the controlled vocabulary terms with social terms more than doubled the average coverage of participants' terms for a photograph. The relationships between user demographics and users' perceptions of the value of terms were also investigated, as well as the relationships between user demographics and indexing quality, as measured by the number of terms participants assigned to a photograph. Participants with more tagging and indexing experience assigned a greater number of tags than did other participants. 相似文献

Value-based metadata quality assessment 总被引：1，自引：0，他引：1
This article proposes a method that allows a value-based assessment of metadata quality and construction of a baseline quality model. The method is illustrated on a large-scale, aggregated collection of simple Dublin core metadata records. An analysis of the collection suggests that metadata providers and end users may have different value structures for the same metadata. To promote better use of the metadata collection, value models for metadata in the collection should be made transparent to end users and end users should be allowed to participate in content creation and quality control processes. 相似文献
