Information Extraction from Broadcast News
This paper discusses the development of trainable statistical models for extracting content from television and radio news broadcasts. In particular we concentrate on statistical finite state models for identifying proper names and other named entities in broadcast speech. Two models are presented: the first represents name class information as a word attribute; the second represents both word-...
متن کاملOverview: Information Extraction from Broadcast News
Broadcast news is a rich domain for information extraction, but one that presents new challenges for evaluation. In this paper we present an overview of the first evaluation of information extraction from broadcast news that was conducted as part of the DARPA-funded Hub 4 1998 workshop. We discuss the work that was required to design and administer the evaluation, describe some of the challenge...
متن کاملInformation Extraction from Broadcast News Speech Data
In this paper we describe a robust algorithm for information extraction from spoken language data. Our probabilistic algorithm builds on results in language modeling, using classbased smoothing to produce state-of-the-art performance for a wide range of speech error rates. We show that our system performs well with sparse data, as well as with out-of-domain data.
متن کاملMining broadcast news data: robust information extraction from word lattices
Fine-grained information extraction performance from spoken corpora is strongly correlated with the Word Error Rate (WER) of the automatic transcriptions processed. Despite the recent advances in Automatic Speech Recognition (ASR) methods, high WER transcriptions are common when dealing with unmatched conditions between the documents to process and those used to train the ASR models. Such misma...
