TUD-MIR at MediaEval 2011 Genre Tagging Task: Query expansion from a limited number of labeled videos
نویسندگان
چکیده
In this paper we present results of our initial research on genre tagging. We approach the task from information retrieval perspective using a relatively small number of labeled videos in the development set to mine query expansion terms characteristic of each genre. We also investigate which sources of information associated with the videos or extracted from their audio channel, e.g. title, description, tags and automatic speech recognition transcripts yield the highest improvement within our query expansion framework. The experiments performed on MediaEval 2011 Genre Tagging dataset demonstrate the effectiveness of our approach.

In this paper, we investigate the internet video categorization problems on genre related labels. The videos are represented by features extracted from different modalities. Then for each category, one-vs-all SVM classifiers are trained based on features from different modalities. The weighted Reciprocal Rank Fusion method is used to combine the classifiers for each modality. The experiments ar...

In this paper we present the second participation of the NLP&IR group at UNED in the MediaEval Genre Tagging Task. This categorization task was carried out applying an Information Retrieval (IR) approach considering the video collection’s textual data and query expansion techniques. The results show that the combination of social tags and language models is useful to perform query expansion.

This paper describes our participation in Genre Tagging Task of MediaEval 2011, which aims to predict the videos’ category label. We use bag-of-words approaches with different features derived from visual content and associated textual information. We perform different experiments in which different constellations in respect of single modalities, classification methods, visual features and thei...
متن کاملLIA @ MediaEval 2011: Compact representation of heterogeneous descriptors for video genre classification
This paper describes our participation in Genre Tagging Task @ MediaEval 2011, which aims at predicting the Genre of Internet videos. We propose a method that extracts low dimensional feature space based on text, audio and video information. In the best configuration, our system yields a 0.56 MAP (Mean Average Precision) on the test corpus.
