Author Identifiers ( [> one (1) identifier per subject]

I happened upon an author who used an author identifier at their webpage.

From the page:

It is a long-term goal of arXiv to accurately identify and disambiguate all authors of all articles in arXiv. Such identification would provide accurate results for queries such as "show me all the other papers by the particular John Smith that wrote this paper", something that can be done only approximately with text-based searches. It would also permit construction of an author-article graph which is useful for relevance
assessment and bibliometric analysis.

Since 2005 arXiv has used authority records that associate user accounts with articles authored by that user. These records support the endorsement system. The use of public author identifiers as a way to build services upon this data is new in 2009. Initially, users must opt-in to have a public author identifier and to expose the record of their articles on arXiv for use in other services. At some later date we hope to be able to improve our authority records to the point where we can create public author identifiers for all authors of arXiv articles without needing to enlist the help of each author to check their record before opting in.

The services we offer based on author identifiers are:

Significant enough in its own right but note the plans for the future:

The following enhancements and interoperability features are planned:

  • arXiv will permit authors to record other identifiers they have in other schemes and include these in the data feeds. This will allow agents and systems to link together the same author in different databases.
  • arXiv will support mechanisms for handling name changes, combination of accidentally created duplicates and separation of accidentally combined identifiers.

Recoding other identifiers? What? Acknowledge that there can be more than one identifier (yours) per subject? Blasphemy! 😉


I am sure suggestions, support, contributions, etc., would be most welcome.
