P06-1061 significantly improved by our segment HMM IE system . The important improvement from
P06-1061 extraction redundancy in the document HMM IE system from Section 2 . We calculate
P06-1061 confidence intervals ) of our Document HMM IE system ( Doc HMM ) . The performance
P06-1061 criterion for evaluating our document HMM IE systems in Section 2 . Although it might
P06-1061 the SGT smoothing method to our HMM IE systems to alleviate the data sparseness
P06-1061 measure the performance of an HMM IE system . Document HMM IE modelling does
P06-1061 evaluating these document-based HMM IE systems . We used the same criterion
P06-1061 extraction performance of the segment HMM IE system . In the future , we intend to
P06-1061 important improvement from the segment HMM IE system that it has achieved zero extraction
P06-1061 system ( Doc HMM ) and the segment HMM IE system ( Seg HMM ) . Compared to the

P06-1061 performance than traditional document HMM IE systems . 2 Document-based HMM IE with
P06-1061 we train an HMM in the document HMM IE system from a set of training documents
P06-1061 possibly extracted by a document HMM IE system , for filling in the slot template
P06-1061 work We evaluated our document HMM IE system on the seminar announcements
P06-1061 comparison between the document HMM IE system ( Doc HMM ) and the segment HMM
P06-1061 segments . The resulting segment HMM IE system using the segment retrieval method
P06-1061 better on all slots than their HMM IE system using absolute discounting .
P06-1061 an issue in the training for an HMM IE system , especially when more advanced
