Poll about new RePEc institution ranking

January 26, 2015

The rankings provided by RePEc are becoming increasingly popular. They are far from perfect, though. One frequent criticism is that institution rankings depend on the size of the institution, as they simply add the scores of all affiliated economists. It is unfortunately not possible to offer per-capita rankings, as the registration system does not distinguish between faculty and students. What one could do, however, is to count only the top x people from every institution. The question is what this x should be.

We want to ask the RePEc community to determine this x with the poll below. The vote will be open for a month, the option closest to the median will be selected.

A few technicalities: As economists with multiple affiliations have to set shares for each, those shares will therefore also be used to determine who counts up to x. This means that more than x people will likely count towards the institution’s score. Also, institutions with fewer than x registered economists will not be compensated for the remainder of the allocation.

Enrichment facilities for papers readers

January 19, 2015

This post is the last in a series on the new enrichment facility on Socionet.

When you are logged into the Socionet system and browse a publication that is not one of yours, you will see close to the bottom of the page the following three menus

The first one allows readers, if they are registered authors with publications linked to their personal profiles, to check a paper from the list of own claimed papers and select a taxonomy value at the drop-down list “Relationship type” in such a form

For this use case we support a taxonomy of recommendations or just useful comments that can be provided by a reader  to the author of the browsed paper based on a content of some publication of the reader. The taxonomy has following values:

You can apply software that I used
Your results are analysed in my publication
Your idea/method/model/results are itemized in my publication
Your data/method/model/results are illustrated in my publication
Your results are interpreted in my publication
My data/method/model are better
Your idea/method/model/results are generalized in my publication
A similar problem is discussed in my publication
Your results are refuted in my publication
I received the same results
Your idea/method/model are implemented in my work
Your errors are detected and corrected in my publication

The second menu is called the “Scientific developments and associations with this publications“. It opens the same form. The taxonomy in this case allows a user to specify the development and complement relationships between a user paper and the currently browsed paper. This taxonomy has been already used in some other use cases and has following values:

uses data from
uses method from
uses a model from
uses software from
uses statistics from
details idea/method/model from
generalizes idea/method/model from
implements idea/method/model from
analyzes results from
illustrates results from
interprets results from
corrects errors in
refines results from
refutes results from
develops results from

The third menu option is called the “Professional opinion on this publication“. It allows readers sharing with the community their opinions about the browsed paper. It opens the same form and provides the same taxonomy as described for the use case of the annotating paper’s abstract. But in this case a user does not need to select a text fragment within an a paper’s abstract to open the form.

A new ecosystem for authors of research papers in RePEc

January 12, 2015

This post is part of a series about the new enrichment facility at Socionet.

RePEc users can use now some new tools and services, which forms together following ecosystem:

A. If a user is logged into the Socionet system, which processes whole RePEc dataset, the user can create different types of semantic linkages between papers, personal profiles, etc. This new users’ facility is illustrated by following main use cases:

1. A user can specify the roles of their co-authorship in the making of a collective paper.

2. A user can annotate text fragments of a paper’s abstract to provide readers with additional and/or newer information on the topic.

3. A user can link their papers together, e.g. to provide information about its open access or newest versions; and to show to readers an evolution of ideas or a development of approaches through a set of own papers.

4. A user can contribute data on how the works referenced in their paper are used.

5. A user can share their professional opinion, or make recommendations, comments  about relationships between their papers and the one that is currently browsed.

B. All user-created outgoing and ingoing semantic linkages are visualized on the paper page together with initial metadata of the paper.

C. All created semantic linkages are processed by the Socionet system on the everyday base to collect statistical data and to build different scientometric indicators. For personal and organizational profiles the statistics are aggregated by links between OrgUnit <-> Person <-> Paper. Such indicators are available for every paper (example), personal (example) or organizational (example) profile. And also for every RePEc archive and series.

D. The community of RePEc user can create new and develop already existed taxonomy of scientific relationships which are used in tools to create semantic linkages. The same they can propose new use cases of using this technique over RePEc dataset. Please send such proposals to me or leave it in comments.

E. The registered users can switch on the e-mail notification service, which will inform them when someone creates/modifies a semantic linkage with their papers, or when someone is changing papers that the user linked together, and so on.

F. Developers of RePEc services can harvest and use the data of all created semantic linkages. The data are freely available by three ways: 1) by FTP from the Socionet server; 2) by OAI-PMH protocol with CERIF output format; 3) by REST API in XML form.

RePEc in December 2014, and a look back at 2014

January 6, 2015

Let us first discuss what is new from last month. First, IDEAS changed its website layout to be more friendly for our users on mobile users. Other RePEc websites will soon follow suit. Second, the NEP-CWA (Central and Western Asia) has been revived. And third, we welcome the following new RePEc archives: University of Tennessee, KSP Journals, Davidson College, Instytut Badañ Strukturalnych, Montana State University, Institute of Agroecology and Environmental Management. For the set of RePEc services that share such statistics, we counted 497,673 file downloads and 1,901,689 abstract views in December 2014.

This all helped us pass the following thresholds last month:

1700000 items listed in RePEc
600000 items with extracted and matched references
500000 working papers with abstracts
400000 cited articles
300000 working papers with JEL codes
1750 participating archives
1000 followers on NEP twitter feeds

Now, what have we acheived in 2014? For one, our archive maintainers (of which there are 122 more) have added a ton of material: over 200’000 works, or an increase of 14%. While 54’000 working papers and 220 new series were added, the big push came from journals with 266 new journals and almost 150’000 new articles indexed in RePEc. Over 4’000 authors are newly registered. We counted 25 million abstract views and over 6 million downloads. The RePEc team has also worked hard to improve the user experiences, making the website more accessible for mobile devices as well as secure, and adding many features: NEP reports are now available through Twitter, CitEc added many new features, and we are now working with the Replication Wiki.

While in some ways one can consider RePEc to be a mature project, it dates back to 1997 in its current form, it is still surprising how much growth it is experiencing. And there is still a lot of potential, especially in terms of enhancing the information disseminated by RePEc. We will see more of that over the next year.
