BBN at TREC Using Hidden Markov Models for Information Retrieval

We present a new method for information retrieval using hidden Markov models HMMs and relate our experience with this system on the TREC ad hoc task We develop a general framework for incorporat ing multiple word generation mechanisms within the same model We then demonstrate that an extremely simple realization of this model substantially outper forms tf idf ranking on both the TREC and TREC a...

BBN at TREC 7 : Using Hidden Markov

We present a new method for information retrieval using hidden Markov models (HMMs) and relate our experience with this system on the TREC-7 ad hoc task. We develop a general framework for incorporating multiple word generation mechanisms within the same model. We then demonstrate that an extremely simple realization of this model substantially outper-forms tf :idf ranking on both the TREC-6 an...

Introducing Busy Customer Portfolio Using Hidden Markov Model

Due to the effective role of Markov models in customer relationship management (CRM), there is a lack of comprehensive literature review which contains all related literatures. In this paper the focus is on academic databases to find all the articles that had been published in 2011 and earlier. One hundred articles were identified and reviewed to find direct relevance for applying Markov models...
