    An empirical study of inter-concept similarities in multimedia ontologies

    Generic concept detection has been a widely studied topic in recent research on multimedia analysis and retrieval, but the issue of how to exploit the structure of a multimedia ontology as well as different inter-concept relations, has not received similar attention. In this paper, we present results from our empirical analysis of different types of similarity among semantic concepts in two multimedia ontologies, LSCOM-Lite and CDVP-206. The results show promise that the proposed methods may be helpful in providing insight into the existing inter-concept relations within an ontology and selecting the most facilitating set of concepts and hierarchical relations. Such an analysis as this can be utilized in various tasks such as building more reliable concept detectors and designing large-scale ontologies

    A lightweight web video model with content and context descriptions for integration with linked data

    The rapid increase of video data on the Web has warranted an urgent need for effective representation, management and retrieval of web videos. Recently, many studies have been carried out for ontological representation of videos, either using domain dependent or generic schemas such as MPEG-7, MPEG-4, and COMM. In spite of their extensive coverage and sound theoretical grounding, they are yet to be widely used by users. Two main possible reasons are the complexities involved and a lack of tool support. We propose a lightweight video content model for content-context description and integration. The uniqueness of the model is that it tries to model the emerging social context to describe and interpret the video. Our approach is grounded on exploiting easily extractable evolving contextual metadata and on the availability of existing data on the Web. This enables representational homogeneity and a firm basis for information integration among semantically-enabled data sources. The model uses many existing schemas to describe various ontology classes and shows the scope of interlinking with the Linked Data cloud

    This paper presents a vision for the future of the e-books as part of the growing collective intelligence. The vision entails further development of technologies that will facilitate the creation and use of a new generation of ‘smart’ books: e-books that are evolving, highly interactive, customisable, adaptable, intelligent, and furnished with a rich set of collaborative authoring and reading support services. The proposed set of tools will be integrated into an intelligent framework for collaborative book authoring and experiencing called SmartBook. The paper also discusses the opportunities to use SmartBook as a vehicle for building professional virtual communities of practice in the framework of a University 2.0 organization dedicated to industry-university cooperation

    Towards NLP-based Semi-automatic Preparation of Content for Language Learning using LingoSnacks m-Learning Platform

    Vocabulary growth is an important element for language learning but it requires repeated and varied exposure to the new words and their usage in different context. However preparing suitable learning content for effective language learning remains a challenging and time-consuming task. This paper reports the experience of designing and developing a m-Learning platform (named LingoSnacks) for semi-automatic preparation of content for language learning using Natural Language Processing (NLP) services. LingoSnacks Authoring Tools provide an environment of assisted authoring of learning content and delivering it to the learner in game-like interactive learning activities. Empirical testing results from teachers who used LingoSnacks indicate that the participants were able to ease their lessons preparation tasks. Also the resulting learning packages helped learners in vocabulary acquisition as the number of new vocabulary that they can recognize, recall and retain was significantly higher that participants who just used conventional lessons in a classroom

    Сучасні інструменти проектування мультимедійних повідомлень студентами радіотехнічних спеціальностей

    У статті описуються переваги та недоліки використання сучасних мультимедійних ресурсів у процесі навчання іноземної мови. Розглядається можливість поліпшити результати навчання студентів за допомогою використання мультимедійних доповідей, як інструменту взаємодії на практичному занятті. Особливу увагу приділено веб-ресурсам у реальному часі, які можуть використовуватись студентами радіотехнічних спеціальностей. Ці ресурси можуть підвищити рівень мотивації до вивчення іноземних мов. Також ми описуємо декілька принципів розробки мультимедійних продуктів, які ґрунтуються на результатах одинадцяти дослідницьких робіт у сучасній науковій літературі. В даній статті термін «мультимедіа» належить до освітньої доповіді з використанням в основному відео-, текстового супроводу та зображень. На відміну від гіпертексту і навчання, заснованого на технологіях веб, увага в мультимедійних продуктах на текстову складову зведена до мінімуму. Результати роботи показують, що мультимедіа протягом багатьох років має високий потенціал розвитку в якості інструменту для викладачів англійської мови. Однак автор підкреслює дві супутні проблеми: до цих пір існує порівняно мало результатів, що свідчать про значення мультимедіа в освітньому середовищі при тому, що вартість мультимедійних продуктів залишається досить високою.The paper describes the advantages and disadvantages of using modern multimedia recourses in the foreign language teaching process. It considers whether multimedia report as a collaborative tool is perceived by radio engineering students as a positive way to improve learning outcomes. Special attention is devoted to the web resources used by students. These resources can increase the level of motivation to learn foreign languages. Also we describe several principles of multimedia design based on eleven research study findings in modern scientific literature. In this paper the term «multimedia» refers to an educational presentation made using primarily video, text and images. Unlike hypertext and web-based instruction the reliance on text is minimized in a multimedia product. The results of the paper show that multimedia has for years been considered high in development potential as a tool for English language teachers. However, the author notices two difficulties: there is still relatively little evidence to support the value of multimedia for enhancing learning and the cost of most multimedia production is still relatively high
