A study of smoothing methods for language models applied to Ad Hoc information retrieval
SIGIR '01: Proceedings of the 24th annual international ACM SIGIR conference on Research and development in information retrievalPages 334–342https://doi.org/10.1145/383952.384019Language modeling approaches to information retrieval are attractive and promising because they connect the problem of retrieval with that of language model estimation, which has been studied extensively in other application areas such as speech ...

Structure and content-based segmentation of speech transcripts
SIGIR '01: Proceedings of the 24th annual international ACM SIGIR conference on Research and development in information retrievalPages 404–405https://doi.org/10.1145/383952.384041algorithm for the segmentation of an audio/video source into topically cohesive segments based on automatic speech recognition (ASR) transcriptions is presented. A novel two-pass algorithm is described that combines a boundary-based method with a ...

Topic segmentation with an aspect hidden Markov model
SIGIR '01: Proceedings of the 24th annual international ACM SIGIR conference on Research and development in information retrievalPages 343–348https://doi.org/10.1145/383952.384021We present a novel probabilistic method for topic segmentation on unstructured text. One previous approach to this problem utilizes the hidden Markov model (HMM) method for probabilistically modeling sequence data [7]. The HMM treats a document as ...
