x-index: A Fantastic New Indicator for Quantifying a Scientist’s Scientific Impact

Xiaojun Wan /  (Submitted on 4 May 2014)

h-index has become the most popular indicator for quantifying a scientist's scientific impact in various scientific fields. h-index is defined as the largest number of papers with citation number larger than or equal to h and it treats each citation equally. However, different citations usually come from different papers with different influence and quality, and a citation from a highly influential paper is a greater recognition of the target paper than a citation from an ordinary paper. Based on this assumption, we proposed a new indicator named x-index to quantify a scientist's scientific impact by considering only the citations coming from influential papers. x-index is defined as the largest number of papers with influential citation number larger than or equal to x, where each influential citation comes from a paper for which the average ACNPP (Average Citation Number Per Paper) of its authors larger than or equal to x . Through analysis on the APS dataset, we find that the proposed x-index has much better ability to discriminate between Physics Prize Winners and ordinary physicists.

Discovering Scholarship on the Open Web: Communities and Methods

Joan Fragaszy Troyano, Project Director 
Jeri Wieringa, Research Assistant 
Last Updated: April 2013

Online publications that aggregate content from a wide variety of sources have become increasingly valuable to readers and publishers. The academy, however, is still unsure how to efficiently identify, collect, survey, evaluate, and redistribute the valuable scholarly writing published both formally and informally on the open web. Fortunately, some scholarly communities are developing methods to draw attention to upcoming work in their fields.

This report outlines the current state of the aggregation, curation, evaluation, and distribution of scholarship on the open web. We describe the primary types of websites where open collections of scholarly work can be found, specifically repositories, aggregators, curated content, and forums for post-publication review. We suggest an eight-point rubric for analyzing similar sources of web-published scholarship. Finally, we offer an annotated bibliography of outlets for scholarly communication on the open web.

Table of Contents

1. Introduction

2. Aggregating and Curating Scholarly Content on the Web 
  • Repositories
  • Collections of Aggregated Content
  • Curated Content
  • Post-publication Review and Community Discussion
3. Conclusion: Moving toward a Rubric

  • Rubric for Scholarly Communication Outlets on the Open Web

4. Appendices 
  • Appendix A: Sites Reviewed 
  • Appendix B: Tools And Services Examined
  • Appendix C: Scholarly Communication Projects on the Open Web

Pundit: Semantically Structured Annotations

Annotating is the act of expressing knowledge about a “resource”. A variety of web annotation tools is appearing on the scene, so how does pundit differ from others?

The main idea behind Pundit is to enable users not only to comment, bookmark or tag web pages, but also to create semantically structured data while annotating, thus enriching the so called Web of Data.

The ability to express semantically typed relations among resources, relying on ontologies and specific vocabularies, not only enables users to express unambiguous and precise semantics, but also, more interestingly, fosters the reuse of such collaboratively created knowledge within other web applications. For example: provide a powerful semantic search, build innovative ad-hoc data visualizations or ultimately improve the way users explore the web.

This picture might give a better idea of what we mean by semantically structured annotations: the ability for users to create knowledge graphs where web content fragments, concepts and entities are meaningfully connected.

Technically, such a knowledge graph is represented using the Resource Description Framework (RDF), the main building block of the so called Semantic Web.

[http://www.thepund.it/introductory-videos/semantically-structured-annotations/]

Pundit enables users to create semantically structured data annotating the web. Annotations are organised in notebooks which can be shared with others to create collaborative structured knowledge. They can be simple comments, semantic links to the Web of Data or fine granular cross-references and citations done between entire pages, paragraphs or any other user-defined granularity, including custom drawn shapes over images. The created data can be exploited to build custom rich visualizations, by querying the server's open API.

SHARE Notification System Project Plan Released


The SHared Access Research Ecosystem (SHARE)—a joint initiative of the Association of Research Libraries (ARL), the Association of American Universities (AAU), and the Association of Public and Land-grant Universities (APLU)—today released the SHARE Notification System Project Plan ... .

The plan details the first in a series of activities to be undertaken by SHARE to ensure that scholarly research outputs are discovered and built upon in a manner that facilitates and accelerates the research process. The SHARE notification system is consistent with higher education’s ongoing mission to encourage community-driven solutions that increase public access to research and maximize knowledge creation.

Funding agencies, sponsored research offices at universities, institutional and disciplinary repositories, and other interested parties have found it difficult to keep abreast of the release of publications, datasets, and other results of scholarly research. Across the disciplines, principal investigators and other scholars do not have any single, structured way to report on these releases in a timely and comprehensive manner. The SHARE Notification System is a higher education–based initiative to strengthen efforts to identify, discover, and track research outputs.

Academic Torrents: Decentralized Platform To Share Papers and Datasets

Researchers from the University of Massachusetts have launched a torrent site which allows academics to share papers and datasets. AcademicTorrents provides researchers with a reliable and decentralized platform to share their work with peers, as well as the rest of the world.

[snip]

The site was launched by Joseph Cohen and Henry Lo, two PhD students working at the University of Massachusetts in Boston. The torrent site aims to provide academics with a cheap and decentralized platform to share their work and data with the rest of the world.

AcademicTorrents allows researchers to upload datasets, articles and other research material. The site runs it own tracker and supports web-seeds as well, which guarantee that files are available at all times.

Keeping Up With... Altmetrics

This edition of Keeping Up With… was written by Robin Chin Roemer and Rachel Borchardt.

Robin Chin Roemer is Instructional Design and Outreach Services Librarian at University of Washington Libraries, email: robincr@uw.edu. Rachel Borchardt is Science Librarian at American University Library, email: borchard@american.edu.

Introduction to Altmetrics

Cites. Tweets. Downloads. Views. In today’s digitally-transformed higher education landscape, the lines between popular and scholarly influence are blurry at best. More and more, scholarly communication is moving away from the strict sphere of conferences and published literature and into Internet-enabled arenas like blogs, institutional repositories, online interdisciplinary communities, and social media sites.

Into this setting, enter altmetrics. Altmetrics is an emerging category of impact measurement premised upon the value of “alternative metrics,” or metrics based distinctly on the opportunities offered by the 21st century digital environment. Originally defined in contrast to the more established field of bibliometrics, altmetrics is fast becoming a fluid area of research and practice, in which various alternative and traditional measures of personal and scholarly impact can be explored and compared simultaneously.

In this Keeping Up With… edition, we look at key points in the rapid development of altmetrics, from its 2010 origins to its more recent relevance to librarians and administrators.
