A query expansion framework in image retrieval domain based on local and global analysis
2011
Information Processing & Management
We present an image retrieval framework based on automatic query expansion in a concept feature space by generalizing the vector space model of information retrieval. ...
We also analyze the concept similarities in the collection as a whole in the form of a similarity thesaurus and propose an efficient query expansion based on the global analysis. ...
We propose automatic query expansion approaches in a concept feature space based on both the local and global analysis. ...

Inter-media Pseudo-relevance Feedback Application to ImageCLEF 2006 Photo Retrieval
[chapter]
2007
Lecture Notes in Computer Science
We show in particular how inter-media re-ranking and pseudo-relevance feedback have been used for producing the results. We have also tested Latent Semantic Analysis (LSA) approach on visual runs. ...
This paper provides a description of the way results has been produced. The text/image database used is IAPR [1]. We have tested a cooperative use of a text retrieval and an image retrieval engine. ...
For visual only runs, Latent Semantic Analysis (LSA) leads to slightly better results compared to retrieval based on visual similarity in the feature space. ...

Semantic concept-based query expansion and re-ranking for multimedia retrieval
2007
Proceedings of the 15th international conference on Multimedia - MULTIMEDIA '07
Three general approaches are illustrated for identifying relevant semantic concepts to a query-based on textual query analysis, visual content-based query modeling, and pseudorelevance feedback. ...
In addition, we study several other recently proposed methods for concept-based query expansion. In total, we compare 7 different approaches for expanding queries with visual semantic concepts. ...
We take a more robust feedback approach, termed probabilistic local context analysis(pLCA) [1] , that automatically leverage useful high-level semantic concepts to improve the initial retrieval output ...

Conference and Labs of the Evaluation Forum
We also test a visual retrieval system based on manual query design and visual task fusion. ...
For images, this knowledge is in semantic features that are learned from examples within structured learning framework. We propose to represent both image and text using UMLS concepts. ...
In the near future, we plan to use the LVM terms from local indexing for semantics-based retrieval (i.e. cross-modal retrieval: processing textual query on LVM-based image indexes). ...

Video Retrieval Based on Semantic Concepts
2008
Proceedings of the IEEE
| An approach using many intermediate semantic concepts is proposed with the potential to bridge the semantic gap between what a color, shape, and texture-based Blowlevel[ image analysis can extract from ...
We illustrate how semantic concept retrieval can be automatically exploited by mapping queries into query classes and through pseudo-relevance feedback. ...
Over and the TRECVID organizers for shepherding the video retrieval evaluations. They are also indebted to W. ...

The Use of Ontology in Retrieval: A Study on Textual, Multilingual and Multimedia Retrieval
2019
IEEE Access
Ontological information retrieval systems retrieve data based on the similarity of semantics between the user query and the indexed data. ...
Trivial keyword-based information retrieval systems highly depend on the statistics of data, thus facing word mismatch problem due to inevitable semantic and context variations of a certain word. ...
Relevance Feedback (RF): is a user response based on-line process in which semantic space between semantic concepts and features is reduced. ...

In this article, we present a semantic image query system with integrated feedback mechanism. Our system has two major components: the low-levelfeature space and the semantic space. ...
In the low-level feature space, images are described by multidimensional vectors and are clustered based on the similarity of their contents. ...
Image Retrieval -, . _ In our image database, a labeled image is retrieved based on its low-level features or its semantic expression. ...

How to Visually Retrieve Images from the St. Andrews Collection Using GIFT
[chapter]
2005
Lecture Notes in Computer Science
The imageCLEF task of the Cross Language Evaluation forum has as its main goal the retrieval of images from multi-lingual test collections, or retrieval of images where the query is in a different language ...
Input for these queries were only the query images. No feedback or automatic query expansion was used. ...
Retrieval systems can then try to find as many of the images with respect to the topic as possible based on visual features only or based on visual and textual features. ...

IEEE Transactions on Pattern Analysis and Machine Intelligence
Given a query keyword, a pool of images are first retrieved based on textual information. ...
By asking the user to select a query image from the pool, the remaining images are re-ranked based on their visual similarities with the query image. ...
