Hi Is there currently implementation of getting Topk segmentation of an address? And How can I get the probability of each segmentation? Thanks Xu |

Hi all I just checked out CRF. I found there are some newly added features to it. Specifically there are four new packages, iitb.AStar, iitb.BSegment, iitb.BSegmentCRF, iitb.KernelCRF. But there aren't enough documentation. Can anyone tell me what are those for? Any reference paper about those packages? Thanks a lot Regards, Xu |

Well, except for the BSegment* package that implement my ICML 2006 paper (Efficient inference on sequence segmentation models), the other packages are quite exploratory and can be ignored.
