Note

The author ID (authorid) can be obtained in either of the following ways:

The API method Get a list of authors lists authors matched some criteria along with their IDs - stored in attribute id of author tag.
When you query for an author from Scholarometer browser extension, the URL of the citation analysis page will be of the form

Introduction
Sample Resources
Links to external datasets
Primary Application

Linked Data is a style of publishing and interlinking structured data on the Semantic Web. In the Semantic Web, data is described and linked using a language called RDF (Resource Description Framework). You can use generic RDF browsers (e.g. Tabulator, Disco, OpenLink Browser), RDF crawlers (e.g. SWSE, Swoogle), and query agents (e.g. SemWeb Client Library, SWIC) to explore the data.

Scholarometer publishes crowdsourced data according to the basic principles of Linked Data. The aim is to make information about authors and disciplines based on citation analysis available on the Semantic Web.

Scholarometer assigns URIs (Uniform Resource Identifiers) to authors and disciplines. We implement an HTTP mechanism called content negotiation in order to provide an HTML representation in addition to the RDF representation of a resource. Some example Linked Data URIs, taken from the Scholarometer dataset, are listed below.

URIs of Authors:

http://scholarometer.indiana.edu/resource/author/authorname

Example:

http://scholarometer.indiana.edu/resource/author/f%20menczer

URIs of Disciplines:

http://scholarometer.indiana.edu/resource/discipline/disciplinename

Example:

http://scholarometer.indiana.edu/resource/discipline/computer%20science

(Note that spaces in URLs are encoded as "%20")

Specific Format:

We allow you to specify the desired format of a resource:

RDF/XML: add "data" to the URI after "resource".

http://scholarometer.indiana.edu/resource/data/author/authorname
http://scholarometer.indiana.edu/resource/data/discipline/disciplinename

HTML: add "page" to the URI after "resource".

http://scholarometer.indiana.edu/resource/page/author/authorname
http://scholarometer.indiana.edu/resource/page/discipline/disciplinename

Scholarometer Vocabulary:

We introduce a new RDF vocabulary to represent impact measures that are not represented in existing vocabularies. The new vocabulary is described at:

http://scholarometer.indiana.edu/namespaces/

Linked Data encourages interlinks between different data sources, which enable Semantic Web browsers and crawlers to navigate between them. In Scholarometer, RDF links primarily point to the following data sets using the owl:sameAs property, which indicates that two URIs refer to the same thing:

DBpedia: a multi-domain ontology derived from Wikipedia
DBLP: bibliographic information about scientific publications
Freebase: an open-license database about millions of things from various domains
Opencyc: an open-license version of the Cyc Ontology

Linking from your HTML webpage or FOAF profile to Scholarometer data

If you are an author, then a URI may already have been created for you in Scholarometer. You can simply add a link from your webpage or FOAF profile to your impact data. If you are not in Scholarometer, don't worry; just install the Scholarometer browser extension and query yourself. We will then serve you the citation-based impact analysis and generate a URI for you.

The example below shows an RDF link from a FOAF profile to Scholarometer, which allows navigation from your profile to your impact analysis data.

<foaf:Person rdf:about="your_foaf_url"> <owl:sameAs rdf:resource = "http://scholarometer.indiana.edu.cn/resource/author/your_name"/> </foaf:Person>
