IRIT @ TRECVid HLF 2009 Audio to the Rescue

This notebook paper describes the six runs submitted for the first participation of IRIT at TRECVid 2009 High-Level Feature Extraction task. They were submitted in an attempt to start answering two research questions: 1. Can acoustic information be of any help in this (historically) video-only task? 2. Are Support Vector Machines robust enough to deal with noisy and unbalanced datasets? The six...

IRIT at CLEF 2004: The English GIRT Task

This paper describes our participation to the monolingual English GIRT task. The main objectives of our experiments were to evaluate the use of Mercure IRS (designed at IRIT/SIG) on domain specific corpus. Two other techniques of automatic query reformulation using WordNet are evaluated.

IRIT @ TRECVid 2010 : Hidden Markov Models for Context-aware Late Fusion of Multiple Audio Classifiers

This notebook paper describes the four runs submitted by IRIT at TRECVid 2010 Semantic Indexing task. The four submitted runs can be described and compared as follows: • Run 4 – late fusion (weighted sum) of multiple audio-only classifiers output • Run 3 – context-aware re-rank of run 4 using hidden Markov model • Run 2 – context-aware late fusion of multiple audio classifiers output with hidde...
