an interesting ICANN development on similar domain names

[Yao Jiankang]

if SWORD's verbal search algorithms (or any other algorithms) can be used to built a similarity words set database, that seems be fine. 
what I mean is that:

For every possible domain label word or TLD word, we can classify it into the  sets of similarity words , finally we can bulit a database including all possible similarity word sets.
 
so there will have many similarity words sets
for example,
 similarity word A set (every word in this set is similar to word A)
similarity word B set (every word in this set is similar to word B)
similarity word C set(every word in this set is similar to word C)
similarity word D set(every word in this set is similar to word D)
...
...

When new word X is encountered by SWORD's verbal search algorithms, this algorithm can decide whether word X can be classified into current similarity word  sets. if yes, we will add word X into the current similarity word set; if not, we can create a new similarity word set.
if this process is repeated, the similarity word set will become larger and the database including all the similarity word sets will become larger.

This database may help us to decide whether new gTLD strings are in user confusion with existing TLDs. It can also help the registry or registrant or registrar to register IDN.
Of course, that kind of database is not easy to be built.

  tring Similarity Algorithm Update -- ICANN staff recently completed a workshop with SWORD, the partner who is assisting ICANN with the creation of an algorithm that will help automate the process for assessing similarity among proposed and existing TLD strings. SWORD's verbal search algorithms are used by various patent and trademark offices throughout the world. SWORD has completed a beta algorithm and reviewed several test cases with ICANN staff. This is being done in order to refine the parameters and discuss how the algorithm could be successfully integrated as a tool to help implement the GNSO's recommendation that new gTLD strings should not result in user confusion with existing TLDs.
