A Layered Bayesian Network Model for Document Retrieval

  title={A Layered Bayesian Network Model for Document Retrieval},
  author={Luis M. de Campos and Juan M. Fern{\'a}ndez-Luna and Juan F. Huete},
We propose a probabilistic document retrieval model based on Bayesian networks. The network is used to compute the posterior probabilities of relevance of the documents in the collection given a query. These computations can be carried out efficiently, because of the specific network topology and conditional probability tables being considered, which allow the use of a fast and exact probabilities propagation algorithm. In the initial model, only direct relationships between the terms in the… CONTINUE READING
