Knowledge Representation for Semantic Multimedia Content Analysis and Reasoning

In this paper, a knowledge representation infrastructure for semantic multimedia content analysis and reasoning is presented. This is one of the major objectives of the aceMedia Integrated Project where ontologies are being extended and enriched to include low-level audiovisual features, descriptors and behavioural models in order to support automatic content annotation. More specifically, the ...

Semantic Indexing and Multimedia Event Detection: ECNU at TRECVID 2012

1 Abstract This year we participated in two tasks: Semantic Indexing (SIN) and Multimedia Event Detection (MED). In this paper, we present our approaches and discuss the evaluation results. Semantic Indexing (SIN): For video semantic indexing, we focus on the performance improvement by using a Weighted Hamming Embedding kernel compared with traditional BoW approaches. Below are the brief descri...

We report on our results in the TRECVID 2011 Multimedia Event Detection (MED) and Semantic Indexing (SIN) tasks. Generally, both of these tasks consist of three main steps: extracting features, training detectors and fusing. In the feature extraction part, we extracted many low-level features, high-level features and text features. We used the Spatial-Pyramid Matching technique to represent the...

Semantic Representation of Multimedia Content

Multimedia documents constitute extremely rich information resources, whose efficacious management is intertwined with the effective capturing of the underlying semantics. The conveyed meaning may span along multiple levels and relates to search and retrieval tasks, much as to the very extraction and interpretation of content descriptions. In this chapter we consider the formal representation o...

Consumer-level multimedia event detection through unsupervised audio signal modeling

In this work1, a novel acoustic characterization approach to multimedia event detection (MED) task for unconstrained and unstructured consumer-level videos through audio signal modeling is proposed. The key idea is to characterize the acoustic space of interest with a set of fundamental acoustic units around which a set of acoustic segment models (ASMs) is built. A vector space modeling techniq...
