|TalkBank||MOR and UD Grammars|
We are currently transitioning the TalkBank system for morphosyntactic analysis from the MOR/POST/MEGRASP system to the UD (Universal Dependencies) system which is described in detail here . We apply UD taggers to TalkBank files using Chris Manning's Stanza system that has been built into the Batchalign program created by Houjun Liu.
The great advantage of UD over MOR is that it is available for many more languages. It also seems to perform as well as or better than MOR for computing dependency relations on the %gra line. However, its control of morphological analysis on the %mor line is not yet as good as MOR. So, for English and a few other languages, we will retain use of MOR for this purpose until we have finally harmonized codes with UD.
As of September 2023, we have tagged these languages in CHILDES using UD: Afrikaans, Dutch, German, Icelandic, Italian, Norwegian, Portuguese, Romanian, and Swedish. We hope to eventually apply UD through Batchalign to all languages in CHILDES. Until that work is completed, users may wish to continue use of MOR through these grammars:
