FINAL DRAFT VERSION TO BE VOTED UPON BY THE ALAC

ALAC Advice to the ICANN Board on String Similarity

On 24 June 2013, as requested by the GAC, the Board New gTLD Program Committee (NGPC) considered the issue of singular and plural strings being confusingly similar and decided to let the original process as documented in the Applicant Guidebook stand (i.e. subject to individual objections).

Events and findings, which have occurred since then, indicate that the transparent, predictable and objective criteria called for by the GNSO New gTLD Policy Recommendations 1 and 9 have not been met, ultimately resulting in Internet end-user confusion.

As examples, recent string similarity objection decisions have ruled:

The ALAC is particularly concerned with the issue of singular versus plural strings. A central issue is that the "confusingly similar" test relies purely on visual similarity. Based on the initial evaluation adding an "s" makes it a recognizably different string. The recent NGPC decision (http://www.icann.org/en/groups/board/documents/minutes-new-gtld-25jun13-en.htm#2.d), re-affirms this position, although several NGPC members expressed regret that the wording of the Applicant Guidebook effectively forced this outcome.

The Applicant Guidebook section 2.2.1.1 describes the string similarity review:

This review involves a preliminary comparison of each applied-for gTLD string against existing TLDs, Reserved Names (see subsection 2.2.1.2), and other applied-for strings. The objective of this review is to prevent user confusion and loss of confidence in the DNS resulting from delegation of many similar strings.

Note: In the Applicant Guidebook, “similar” means strings so similar that they create a probability of user confusion if more than one of the strings is delegated into the root zone.

The visual similarity check that occurs during Initial Evaluation is intended to augment the objection and dispute resolution process (see Module 3, Dispute Resolution Procedures) that addresses all types of similarity.

The ALAC disagrees with the NGPC decision. The problem is the belief that "visual similarity" relies purely on what would be called "pattern matching" in computer terminology. Pattern matching is certainly part of human perception, but it is not limited to that issue alone. At issue is whether two strings will be PERCEIVED as being equivalent, and perception is a far more complex (and less understood) issue.

Consider strings pairs such as:

Will these be memorably equivalent or different to typical Internet users, individuals who have no knowledge of terms such as ICANN, domain name, TLD and second level? The ALAC strongly doubts that most Internet users will note the subtle differences.

If both singular and plural TLDs are delegated:

The ALAC advises the Board to revisit the issue of new TLD strings, which are singular and plural versions of the same word, and ensure that ICANN does not delegate strings that are virtually certain to create confusion among Internet users and therefore result in loss of faith in the DNS.

The ALAC is also concerned with the lack of predictability and consistency in objection decisions. Allowing identical strings to be individually evaluated (based on different arguments and by different panelists) opens the door to inconsistent decisions. Moreover the clear lack of consistency among the evaluations of different panelists implies that overall, ICANN will either put some TLDs in contention sets where it is not justified, or delegate strings that will cause user confusion.

It is not clear how this can be fixed at this time, but proceeding with no change is either going to unfairly disadvantage some applicants and their target markets or cause guaranteed user confusion.

The ALAC advises the Board to:

It is not clear how this can be fixed at this time, but proceeding with no change is either going to unfairly disadvantage some applicants and their target markets or cause certain user confusion.

The ALAC advises the Board to review not only the obvious cases such as .cam/com where conflicting objection decision have forced such review, but the general case and determine a viable way forward which will not create contention sets where it is unwarranted, nor delegate multiple TLDs destined to ensure user confusion and implicit loss of faith in the DNS.
