The Flickr Commons was created as a forum for institutions to share their rich photographic collections with the emerging
Web 2.0 audience of Flickr; the Smithsonian Institution was the fourth member of the Commons. The Smithsonian effort was a
direct collaborative effort of the libraries, archives, museums, and information technology staff that generated new pathways
for collaboration between these units. As the world’s largest museum complex, these Smithsonian units serve as a microcosm
for collaboration in the information age. The Flickr Commons project provided insights into how the knowledge, skills, and
abilities of libraries, archives, and museums (LAM) can converge in the Web 2.0 environment to provide collection access to
new, and in some cases unknown, audiences. Simultaneously, by putting “LAM” content into an environment that allows for direct
interaction by these audiences, the knowledge of the content for holding institutions is enriched. By exposing Smithsonian
content within the Flickr environment, the Institution is learning what content is desired by the Web 2.0 world, how to bring
crowd-sourcing into professionally curated collections, and how to bring diverse institutional skills together in a collaborative
project. 相似文献

Carol McCormick was Learning Resources Advisor in the library at James Cook University Hospital, South Teesside when she completed her BSc (Hons) Librarianship (Work Based Learning) degree at Northumbria University. She gained a 1st Class Honours and is now Learning Resources Librarian. Carol's dissertation formed part of a wider action research project into the provision of current awareness services at James Cook University Hospital. This article reports on the evaluation which was conducted after a Web 2.0 Startpage, or portal, had been introduced to improve access to current awareness information for all staff within the Trust. It is the second article in the Dissertations into practice series to examine the use of web‐based tools to improve access to information for NHS staff. AM 相似文献

Objectives:
The research evaluated participant satisfaction with the content and format of the “Web 2.0 101: Introduction to Second Generation Web Tools” course and measured the impact of the course on participants'' self-evaluated knowledge of Web 2.0 tools.Methods:
The “Web 2.0 101” online course was based loosely on the Learning 2.0 model. Content was provided through a course blog and covered a wide range of Web 2.0 tools. All Medical Library Association members were invited to participate. Participants were asked to complete a post-course survey. Respondents who completed the entire course or who completed part of the course self-evaluated their knowledge of nine social software tools and concepts prior to and after the course using a Likert scale. Additional qualitative information about course strengths and weaknesses was also gathered.Results:
Respondents'' self-ratings showed a significant change in perceived knowledge for each tool, using a matched pair Wilcoxon signed rank analysis (P<0.0001 for each tool/concept). Overall satisfaction with the course appeared high. Hands-on exercises were the most frequently identified strength of the course; the length and time-consuming nature of the course were considered weaknesses by some.Conclusion:
Learning 2.0-style courses, though demanding time and self-motivation from participants, can increase knowledge of Web 2.0 tools.Highlights
- Course participants'' knowledge of Web 2.0 tools increased significantly.
- Medical Library Association members liked the online course format, particularly the hands-on exercises and self-pacing.
- There was no significant difference in course completion rate or course satisfaction among participants from academic, hospital, or other library settings.
- Few survey respondents pointed specifically to workplace technology blocking as a reason for non-completion, though this underestimates the effect of such blocking on hospital and corporate library staff.
Implications
- MLA members appreciate having online continuing education (CE) courses. New short, online CE courses were developed based on the findings of this survey.
- Hands-on exercises may improve learning and increase motivation.
- Time and self-motivation are necessary for completing online courses.

The TREC 2009 web ad hoc and relevance feedback tasks used a new document collection, the ClueWeb09 dataset, which was crawled
from the general web in early 2009. This dataset contains 1 billion web pages, a substantial fraction of which are spam—pages
designed to deceive search engines so as to deliver an unwanted payload. We examine the effect of spam on the results of the
TREC 2009 web ad hoc and relevance feedback tasks, which used the ClueWeb09 dataset. We show that a simple content-based classifier
with minimal training is efficient enough to rank the “spamminess” of every page in the dataset using a standard personal
computer in 48 hours, and effective enough to yield significant and substantive improvements in the fixed-cutoff precision
(estP10) as well as rank measures (estR-Precision, StatMAP, MAP) of nearly all submitted runs. Moreover, using a set of “honeypot”
queries the labeling of training data may be reduced to an entirely automatic process. The results of classical information
retrieval methods are particularly enhanced by filtering—from among the worst to among the best. 相似文献

We investigate temporal factors in assessing the authoritativeness of web pages. We present three different metrics related
to time: age, event, and trend. These metrics measure recentness, special event occurrence, and trend in revisions, respectively.
An experimental dataset is created by crawling selected web pages for a period of several months. This data is used to compare
page rankings by human users with rankings computed by the standard PageRank algorithm (which does not include temporal factors)
and three algorithms that incorporate temporal factors, including the Time-Weighted PageRank (TWPR) algorithm introduced here. Analysis of the rankings shows that all three temporal-aware algorithms produce rankings more
like those of human users than does the PageRank algorithm. Of these, the TWPR algorithm produces rankings most similar to human users’, indicating that all three temporal factors are relevant in page
ranking. In addition, analysis of parameter values used to weight the three temporal factors reveals that age factor has the
most impact on page rankings, while trend and event factors have the second and the least impact. Proper weighting of the
three factors in TWPR algorithm provides the best ranking results. 相似文献

ABSTRACTOne of the big challenges facing academic libraries today is to increase the relevance of the libraries to their user communities. If the libraries can increase the visibility of their resources on the open web, it will increase the chances of the libraries to reach to their user communities via the user's first search experience. BIBFRAME and library Linked Data will enable libraries to publish their resources in a way that the Web understands, consume Linked Data to enrich their resources relevant to the libraries' user communities, and visualize networks across collections. However, one of the important steps for transitioning to BIBFRAME and library Linked Data involves crosswalks, mapping MARC fields and subfields across data models and performing necessary data reformatting to be in compliance with the specifications of the new model, which is currently BIBFRAME 2.0. This article looks into how the Library of Congress has mapped library bibliographic data from the MARC format to the BIBFRAME 2.0 model and vocabulary published and updated since April 2016, available from http://www.loc.gov/bibframe/docs/index.html based on the recently released conversion specifications and converter, developed by the Library of Congress with input from many community members. The BIBFRAME 2.0 standard and conversion tools will enable libraries to transform bibliographic data from MARC into BIBFRAME 2.0, which introduces a Linked Data model as the improved method of bibliographic control for the future, and make bibliographic information more useful within and beyond library communities. 相似文献
