| Abstract: |
| The authors proposed the concept of reduce probability and derive probability. With the modifications on the I/O algorithm, the probability parameters of general context free grammar can be trained from unanalyzed corpus. |
| Key words: Inside outside algorithm derive probability reduce probability corpus. |
