Relevance-Based Language Models
Victor Lavrenko,W. Bruce Croft +1 more
TL;DR: This work proposes a novel technique for estimating a relevance model with no training data and demonstrates that it can produce highly accurate relevance models, addressing important notions of synonymy and polysemy.
Proceedings ArticleDOI
Automatic image annotation and retrieval using cross-media relevance models
TL;DR: The approach shows the usefulness of using formal information retrieval models for the task of image annotation and retrieval by assuming that regions in an image can be described using a small vocabulary of blobs.
Proceedings ArticleDOI
Multiple Bernoulli relevance models for image and video annotation
TL;DR: This work shows how it can do both automatic image annotation and retrieval (using one word queries) from images and videos using a multiple Bernoulli relevance model, which significantly outperforms previously reported results on the task of image and video annotation.
Proceedings Article
A Model for Learning the Semantics of Pictures
TL;DR: An approach to learning the semantics of images which allows us to automatically annotate an image with keywords and to retrieve images based on text queries using a formalism that models the generation of annotated images.
