Fine-grained hidden markov modeling for broadcast-news story segmentation
Warren R. Greiff, Alex A. Morgan, Randall K. Fish, Marc Richards, Amlan Kundu · 2001
We present the design and development of a Hidden Markov Model for the division of news broadcasts into story segments. Model topology, and the textual features used, are discussed, together with the non-parametric estimation techniques that were employed for obtaining estimates for both transition and observation probabilities. Visualization methods developed for the analysis of system performance are also presented.
