Subject Can't get correct co-occurrence count
Date Wed, 06 Jun 2012 17:25:44 GMT
Hi All:

I can't get correct co-occurrence count from the ItemSimilarity job;

The following parameters are used:   --similarityClassname, "SIMILARITY_COOCCURRENCE", "--booleanData",
"true", --maxSimilaritiesPerItem, "60"

I run the job on a pseudo distributed hadoop environment.

The scope of uid:   81916  -  88854 

The scope of itemId : 1000156527 - 9999751116

I am not sure if there is any bug in item index algorithm.







Thanks and regards !
