Towards Multimedia Opinion Mining*
Both opinion mining and multimedia retrieval are active research areas with challenging applications, but as far as we know the present vision paper is the first attempt to integrate them into multimedia opinion mining. Here we address the specific case of satirical comments in politics by exploiting the presence of photomontage to infer a tendentially negative opinion. In order to do so, we in...
متن کاملRetrieval of Diverse Images by Pre-filtering and Hierarchical Clustering
In this paper, we describe our approach and its results for MediaEval 2014 Retrieving Diverse Social Images Task. The basic idea of our proposed method is to filter out non-relevant images at the beginning of the process and then construct a hierarchical tree which allows to cluster the images with different criteria on visual and textual features. Experimental results shown that it is stable a...
متن کاملA joint asymmetric watermarking and image encryption scheme
Here we introduce a novel watermarking paradigm designed to be both asymmetric, i.e., involving a private key for embedding and a public key for detection, and commutative with a suitable encryption scheme, allowing both to cipher watermarked data and to mark encrypted data without interphering with the detection process. In order to demonstrate the effectiveness of the above principles, we pre...
متن کاملMultimodal-based Diversified Summarization in Social Image Retrieval
In this paper, we describe our approach and its results for the MediaEval 2015 Retrieving Diverse Social Images task. The main strength of the proposed approach is its flexibility that permits to filter out irrelevant images, and to obtain a reliable set of diverse and relevant images. This is done by first clustering similar images according to their textual descriptions and their visual conte...
متن کاملGlocal Multimedia Retrieval
Personal experience is intrinsically local while common knowledge is global. As a consequence, standard multimedia search engines suffer from a gap between local content and global concept, due to the diversity of context. Here we design a new multimedia retrieval system which integrates local diversity into an evolving global knowledge. A suitable personalization of global ontologies allows to...
