Web1 sep. 2024 · In a seminal paper on model-based IR, Wei and Croft introduced LDA-based IR [19], a term-weighting scheme computed in the latent space of document topics. The model’s core is based on the query likelihood model for IR [20], in which each document is scored by the likelihood of its topic model generating the formulated query.
