Dear colleagues, I updated the routines for generating Korean word/document matrices (including word frequency counts, co-occurrence, and cosine-normalized matrices in the Pajek format) for 64-bits operating machines at http://www.leydesdorff.net/software/korean . I acknowledge Han Woo Park for the functional specification. The routines for Chinese (at http://www.leydesdorff.net/software/chinese) are a bit different.
