摘要: 1 Terabyte 1.1 Model The retrieval model implemented in the Indri search engine is an enhanced version of described [30], which combines language modeling [35] and inference network [38] approaches to information retrieval. resulting allows structured queries similar those used INQUERY [4] be evaluated using estimates within network, rather than tf.idf estimates. Figure shows a graphical representation network. As original framework, documents are ranked according P (I|D,α, β), belief need I met given document D hyperparameters α β as evidence. Due space limitations, general understanding framework assumed. See [30] fill any missing details.
