Lda-based document models for ad-hoc retrieva
WebSkip 1INTRODUCTION Section 1 INTRODUCTION. Ranking models are central to information retrieval (IR) research.With the advance of deep neural networks, we are witnessing a rapid growth in neural ranking models (NRMs) [12, 26, 58, 63], achieving new state-of-the-art results in learning query-document relevance patterns.Recent research … WebLDA-based Document Models For Ad-hoc Retrieval IF:9 Related Papers Related Patents Related Grants Related Orgs Related Experts View Highlight: In this paper, we study how to efficiently use LDA to improve ad-hoc retrieval.

WebNMF and LDA models produce topic-word and document-topic distributions, so you can compare these models on evaluation tasks of topic coherence (i.e. evaluating topic-word distributions), document clustering/classification (i.e. evaluating document-topic distributions) or information retrieval (i.e. evaluating topic-word and document-topic … WebLDA-based document models for ad-hoc retrieval were proposed by Xing Wei et al. From the paper, the authors did an experiment show that directly employing the LDA combine the original document model with the LDA model and construct a new LDA-based document model. They formulate the model through a linear combination
WebRecently, log-bilinear language model (LBL), as a form of neural language model, has been proved to be an effective way to learn semantic word representations, but its feasibility … Webmixture of unigrams model, groups documents into a finite set of clusters (topics) and associates each cluster with a multinomial distribution over the vocabulary. Later, Wei and Croft [12] proposed an LDA-based retrieval model by combining language estimation based on LDA with query likelihood model. Their results showed that the LDA-based
