Revisiting the dependence language model for information retrieval

Loïc Maisonnasse, Eric Gaussier, Jean-Pierre Chevallet
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
In this paper, we revisit the dependence language model for information retrieval proposed in [1] , and show that this model is deficient from a theoretical point of view.  ...  We then propose a new model, well founded theoretically, for integrating dependencies between terms in the language model.  ...  DEPENDENCE LANGUAGE MODELS [1] introduces a dependence language model (that we will refer to as DLM) for IR which, based on the standard language model ( [5] ), integrates syntactic dependencies in  ...

A New Language Model Combining Single and Compound Terms

Arezki Hammache, Rachid Ahmed-Ouamer, Mohand Boughanem
2011 2011 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology  
Particularly in language modeling approaches this is achieved through the use of the bigram or n-gram models. However, in these models all bigrams/n-grams are considered and weighted uniformly.  ...  Most traditional information retrieval systems are based on single terms indexing.  ...  For this purpose, we propose in this section a mixture language model (LM_CT) for information retrieval which combines single terms and compound terms language models.  ...

Revisiting the "Video" in Video-Language Understanding [article]

Shyamal Buch, Cristóbal Eyzaguirre, Adrien Gaidon, Jiajun Wu, Li Fei-Fei, Juan Carlos Niebles
2022 arXiv   pre-print
Building on recent progress in self-supervised image-language models, we revisit this question in the context of video and language tasks.  ...  We propose the atemporal probe (ATP), a new model for video-language analysis which provides a stronger bound on the baseline accuracy of multimodal models constrained by image-level understanding.  ...  This work is supported in part by Toyota Research Institute (TRI), the Stanford Institute for Human-Centered AI (HAI), Samsung, NDSEG Fellowship (for S.B.).  ...

Revisiting the Divergence Minimization Feedback Model

Yuanhua Lv, ChengXiang Zhai
2014 Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management - CIKM '14  
In this paper, we revisit a PRF method based on statistical language models, namely the divergence minimization model (DMM).  ...  Pseudo-relevance feedback (PRF) has proven to be an effective strategy for improving retrieval accuracy.  ...  We argue that, although the smoothing methods using a collection language model, such as the Dirichlet prior smoothing, have been shown to be effective for smoothing document language models in retrieval  ...
