The use of video segmentation as an early processing step in video analysis lags behind the use of image segmentation for image analysis, despite many available video segmentation methods. A major reason for this lag is simply that videos are an order of magnitude bigger than images; yet most methods require all voxels in the video to be loaded into memory, which is clearly prohibitive for even...

Adolescent suicide is now a major health concern for many countries. However, there is paucity of systematic studies and lack of official statistics on adolescent suicide in Ghana. Mass media coverage of adolescent suicide (even though crude), at least, may reflect the reality of the phenomenon. With an ecological orientation, this study used qualitative content analysis to analyse the pattern ...

BACKGROUND Approximately 5.5 million Americans are living with Alzheimer's disease (AD) in 2017. YouTube is a popular platform for disseminating health information; however, little is known about messages specifically regarding AD that are being communicated through YouTube. OBJECTIVE This study aims to examine video characteristics, content, speaker characteristics, and mobilizing informatio...

Social media provides a platform where users share an abundance of information on anything and everything. The information may consist of users’ emotions, feedbacks, reviews, and personal experiences. In this research a novel Ontology-based Sentiment Analysis Process for Social Media content (OSAPS) with negative sentiments is presented. The social media content is automatically extracted from ...

Intelligent systems for the annotation of media content are increasingly being used for the automation of parts of social science research. In this domain the problem of integrating various Artificial Intelligence (AI) algorithms into a single intelligent system arises spontaneously. As part of our ongoing effort in automating media content analysis for the social sciences, we have built a modu...

Lots of repetition units exist in digital multimedia especially television programmes and other kinds of broadcastings. In this paper a new information compression algorithm named Auditory Content-Based Information Compression (ACBIC) is proposed to detect repeated programme segments in order to further reduce information redundancy. This algorithm is quite different from former data compressio...

The analysis of media content has been central in social sciences, due to the key role that media plays in shaping public opinion. This kind of analysis typically relies on the preliminary coding of the text being examined, a step that involves reading and annotating it, and that limits the sizes of the corpora that can be analysed. The use of modern technologies from Artificial Intelligence al...

Social media have been adopted by many businesses. More and more companies are using social media tools such as Facebook and Twitter to provide various services and interact with customers. As a result, a large amount of user-generated content is freely available on social media sites. To increase competitive advantage and effectively assess the competitive environment of businesses, companies ...
