This paper describes the SIAM demonstrator, a system that illustrates the usefulness of indexing multimedia segments thanks to associated microblog posts. From a socialized multimedia content (i.e. video and associated microblog posts on Twitter), the system applies text mining techniques and derives a topic model to index socialized multimedia segments. That result may then be used inside many...

Recently permutation multimedia ciphers were broken in a chosen-plaintext scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-text only attack on speech permutation ciphers. We show inherent redundancies of speech can pave the path for a successful cipher-text only attack. To that end, regularities ...

The demand for fast access of multimedia content is growing exponentially, but unfortunately the advancement in technology is not so fast. A variety of annotation techniques are proposed by the researcher in literature, but still the demand for general annotation mechanism is exists. Among different techniques available for annotation the text analysis is the first hand technique that allows th...

This position paper deals with queries beyond text, mixing several multimedia contents: audio, video, image and text. Search approaches combining some of these formats have been studied, including query by example techniques in situations where only one format is considered. It is worth mentioning that most of these research works do not deal with text content. A new approach to allow users int...

According to cognitive load theory (Sweller, 1999) and Mayer's theory of multimedia learning (Mayer, 2001), replacing visual text with spoken text (the modality effect) and adding visual cues relating elements of a picture to the text (the cueing effect) increase the effectiveness of multimedia instructions. The aim of this study was to test the generalisability of both effects in a classroom s...

The reported study examined whether the degree of spatial information conveyed through a text influences the effectiveness of multimedia presentations. It was assumed that the processing of spatial text contents might interfere in the visuo-spatial sketchpad with the execution of eye movements, associated with looking at pictures and reading. Accordingly, performance impairments were expected w...

The creation and editing of interactive computer-based presentations which combine text, graphics, audio, and video is called multimedia authoring. Contemporary tools provide both media editing and multimedia composition as well as more specialized services including database and file access, courseware support, and extensibility. Such tools make it possible to design sophisticated presentation...

The emergence of mobile communication and positioning technologies has presented advertisers and marketers with a radically innovative advertising channel: Location-Based Advertising (LBA). Despite the growing attention given to LBA, little is understood about the differential effects of text and multimedia advertising formats on the mobile consumer perceptions and behaviours. This exploratory ...

Multimedia documents place new requirements on the conventional text retrieval systems. This paper presents a multimedia retrieval system that employs the contentbased strategy to retrieve both text and speech documents. Its input can be a sequence of spoken words which are digitized waveforms or a sequence of characters, and its output is a list of ranked text and/or speech documents. In this ...
