Abstract:

Multimedia information has been extensively growing from a variety of sources such as cameras or video recorders. In order to select the useful multimedia objects, multimedia recommender system has been emerging as a tool to help users choose which multimedia objects might be interesting for them. However, given the complexity of multimedia objects, it is challenging to provide effective multimedia recommendations. In this paper, we therefore conduct a survey in both the multimedia information system and recommender system communities. We further focus on the works that span the two communities, especially the research on multimedia recommender systems. Based on our review, we propose a set of research challenges, which can be used to implicate the future research directions for multimedia recommender systems. For each research challenge, we have also provided the insights of how to perform the follow-up research.

Abstract:

At present, the research on the theoretical system of multimedia image linguistics in my country is very limited. In order to further improve and develop the theoretical system of multimedia picture linguistics, this article extracts effective knowledge from the research results of educational technology, linguistics, psychology, and semiotics and establishes a teaching system based on image linguistics. Multimedia picture linguistics consists of three parts: structure, semantics, and pragmatics, corresponding to the artistic laws of multimedia pictures, the cognitive laws of multimedia pictures, and the humanization and naturalization of picture design. Therefore, the research in this article is an important part of establishing multimedia image linguistics. Starting from the research methods of multimedia technology and picture linguistics, this article introduces the theoretical framework and the relationship between the multimedia learning cognitive theory and Mayer’s multimedia learning cognitive theory and conducts in-depth discussion and demonstration. The thesis constructs a teaching system that combines picture linguistics and multimedia technology and makes it a language tool for developing and designing multimedia learning materials. Experiments have proved that the teaching system combining picture linguistics and multimedia technology proposed in this paper can provide a framework, ideas, and methods for the related research of multimedia picture linguistics and multimedia technology and make multimedia picture language a multimedia learning material design and development The language tools that can be followed can effectively improve the teaching effect under the background of information technology.

Abstract:

In order to study the special production, distribution, transportation, and sales of short-lived and short-lived multimedia products, this paper studies the cost and benefit optimization of a three-level supply chain network consisting of a supplier-producer-distribution center. Simultaneously, to effectively describe the actual inventory level of the retailer’s multimedia products, this paper introduces a new nonlinear function to define the real-time inventory of multimedia products to establish a biobjective nonlinear mixed-integer programming model to estimate the inventory. The research results show that the model established in this paper can not only provide the overall cost and optimal decision-making plan for the short-lived dairy supply chain but also the design method is better than the standard constraint method. Relevant research results have important potential guiding significance for research and design of supply chain network structure, measurement of multimedia product inventory levels, and improvement of customer satisfaction. The optimized design of the logistics supply chain of multimedia products with short life cycle under the background of new retail is beneficial.

Abstract:

Despite the wide usage of multimedia in several applications, research in the field of olfaction is immature in helping humans work and communicate through multi-sensory interfaces, including smell. There is no consistent method of testing user capability of smell. Therefore, smell detection and generation systems are not well integrated into today’s multimedia systems. In this paper, the authors propose an odor sensing system with the capability of the discrimination among closely similar 20 different odor patterns and propose an on-line classification method using a handheld odor meter (OMX-GR sensor) and neural network that can be used in different multimedia applications. The proposed system is integrated to enhance the functionality of an online multimedia shopping system that is capable of selling products with visual and auditory senses.

Abstract:

This paper describes ongoing research directed at formulating a set of appropriate measures for assessing and ultimately predicting effort requirements for multimedia systems development. Whilst significant advances have been made in the determination of measures for both transaction-based and process-intensive systems, very little work has been undertaken in relation to measures for multimedia systems. A small preliminary empirical study is reviewed as a precursor to a more exploratory investigation of the factors that are considered by industry to be influential in determining development effort. This work incorporates the development and use of a goal-based framework to assist the measure selection process from a literature basis, followed by an industry questionnaire. The results provide a number of preliminary but nevertheless useful insights into contemporary project management practices with respect to multimedia systems.

Abstract:

The performance indicators corporate multi-service networks based on the architectural concept of the following Next Generation Network (NGN) and Future Networks (FN) using a number of innovative technologies are considered. A significant difference between such networks and previous generation networks is that the architecture of future networks is based on technologies software defined networks, virtualization network functions and the multimedia communications subsystem. As a criterion for complex performance indicators corporate multiservice networks, we selected throughput, the coefficient effective use hardware and software systems, various resources, and probability-time characteristics. As a result of the study, a method for calculating the complex throughput indicators corporate multiservice networks based on the architectural concept NGN and FN using SDN (Software Defined Networking), NFV (Network Functions Virtualization) and IMS (Internet Protocol Multimedia Subsystem) technologies is proposed. Th essence of the new method is to find relationships with which you can calculate the maximum throughput of the communication network and the areas feasible solutions of the basic equation that belong to it. System and technical analysis showed that the transmitted heterogeneous traffic has a special structure – self-similarity properties (scale invariance) and a quantitative assessment of the degree traffic self-similarity using the Hurst parameter. Based on the proposed calculation method, the complex indicators of corporate multiservice networks are examined taking into account the parameters traffic self-similarity, QoS (Quality of Service) and QoE (Quality of Experience). Resource management methods in network nodes were studied to improve the throughput characteristics taking into account the numerous QoS & QoE parameters and the coefficient effective use hardware and software systems was determined. Based on the calculation method, analytical expressions have been obtained to evaluate the complex indicators corporate multiservice networks in establishing connections and in providing multimedia services with the necessary parameters. A numerical analysis is carried out and a graphical dependence of the maximum network throughput on the total number software and hardware systems is constructed for a given system load factor.

Abstract:

A multimedia training program for community college faculty includes research results in its training. Recent research in computer assisted multimedia instruction is examined and summarized. Changes in the technology of instruction are described and illustrated. A description of the pedagogical relevance of research to teacher training is offered. The facilities, activities, and outcomes of an instructional multimedia training project for faculty at San Juan College are described. The current principles of instructional systems design, identified by a survey of current research in cai, reflect a pedagogical shift from behaviorism through cognitivism to constructivism. Current research in cai reports that multimedia improves the effectiveness of cai, but provides little consistent empirical evidence explaining why. Questions about learner feedback and control have led to useful results in control/display ergonomics. Continued development of effective, artificially-intelligent tutoring systems has benefited from wider progress in expert systems. Research findings demonstrate that the immanent complexity of hypermedia requires methodical management, that cognitive factors limit the optimum number and effective types of hypermedia link displays, and that close monitoring of learner-system interaction reveals important cognitive differences in individual learners. That same close monitoring of interaction also enables complex instructional systems to respond differentially, thus effectively, across broad differences among individual learners. Different schools of pedagogical thought offer different theoretical explanations for cai's efficacy, but in practice cai's increasing capacity to address individual differences in learning processes is re-emphasizing the importance of teachers' ability to do the same.

Abstract:

In the context of the rapid development of wireless communication and information technology, the network has greatly shortened the actual spatial distances around the world. Multimedia technology and wireless communication, as an important branch of information technology, can better connect people and the network, exploding very powerful energy in the field of education. This research analyzes the cultural communication function of wireless communication and multimedia network technology in university teaching, especially English teaching. At this stage, almost all universities in our country are using multimedia technology to assist teaching, and even many teachers believe that multimedia has become a necessary foundation for the in-depth development of the “teaching-learning” interaction in colleges and universities in the information age. The demand for English talents in the Chinese labor market is dominated by application-oriented talents, but the purpose of English teaching in many schools is still in the reality of traditional research-based teaching. It is concluded that the root of this contradiction lies in the disconnection between the cultivation of talents in universities and the needs of society. The experimental results show that if the advantages of wireless communication and multimedia network technology can be fully utilized, the teaching efficiency of cultural communication in college English teaching can be increased by 22%. This article also analyzes, discusses, and summarizes the methods and approaches of cultural dissemination to enrich academic research results.

Since there is not yet an accepted solution to the problem of how to represent, organize and manage multimedia data and the related semantics by means of a formal framework, this paper aims at providing some major research trends in this area. The focus is on ontologies, which allow the exchange of semantics of multimedia content between distributed information systems. This paper aims at reporting on recent trends in the development of multimedia ontologies.

Abstract:

Introduction:Electronic medical healthcare systems are becoming the backbone of health organizations over the world. The huge amounts of medical multimedia produced by these systems especially images and videos are transmitted by the computer networks that connect these systems. The variability in the shape and texture of transferred medical multimedia data needs adaptable procedures to process these data efficiently. In other words, these procedures must adjust automatically based on the shape of region of interests in the medical multimedia images to cope with fast changes in the healthcare environments. In this paper, we have proposed shape adaptable watermarking approaches for medical multimedia processing systems. The medical images generated by X-rays, MRI and CT modalities are used in our experiments to test proposed approaches. In addition, these approaches were tested under different kinds of signal processing and geometric attacks. The comparative comparison of our proposed approaches with state-of-art approaches proved the superiority and capability of our approaches to adjust the number of selected subands of medical cover image to embed and extract the hospital watermark logos.Background and Objective:The development of an adjustable approach to process medical multimedia signals for healthcare system. The aim of this research is to select adaptably the number of subands of cover image to hide the information of hospital logo watermark inside them such that embedded watermarks can resist different kinds of attacks.Method:The proposed adjustable approach consists of suband selection method, criterion, embedding and extraction procedures, DWT transform, attacks, evaluation metrics,etc.Results & Conclusion:It provides robust and adjustable method to embed and extract watermark logo at different resolution levels of cover medical image and uses with images of different sizes and modalities.

Abstract:

The popularity of research on intelligent multimedia services and applications is motivated by the high demand of the convenient access and distribution of pervasive multimedia data. Facing with abundant multimedia resources but inefficient and rather old-fashioned keyword-based retrieval approaches, Intelligent Multimedia Systems (IMS) demand on (i) effective filtering algorithms for storage saving, computation reduction, and dynamic media delivery; and (ii) advanced learning methods to accurately identify target concepts, effectively search personalized media content, and enable media-type driven applications. Nowadays, the web based multimedia applications become more and more popular. Therefore, how to utilize the web technology into multimedia data management and retrieval becomes an important research topic. In this paper, the authors developed a web-based intelligent video retrieval system that integrates effective and efficient MCA-based filtering and subspace-based learning to facilitate end users to retrieve their desired semantic concepts. A web-based demo shows the effectiveness of the proposed intelligent multimedia system to provide relevant results of target semantic concepts retrieved from TRECVID video collections.

Abstract:

In this study, college undergraduate students were presented identical material on the domain of intelligent tutoring systems. The author designed his research to isolate the key variables, disallow for the effect of some of those variables, and determine in a precise way what effects are produced by a multimedia delivery system, repetition of instructional and testing material, and an intelligent tutoring system delivery system. The first phase of this study, comparing test scores of students who were presented material in two delivery systems: 1) hard-copy (printed material), and 2) a computer-based multimedia program, indicated no statistically significant difference in scores. A second part of that phase, comparing test scores and re-test scores of students studying the computer-based multimedia program, indicated no statistically significant difference in scores. The second phase of this study, comparing scores of the two initial delivery systems and scores on a multimedia modified intelligent tutoring system, resulted in a statistically significant difference in scores.

Abstract:

Multimedia case studies are effective constructivist instructional tools that can help to design contextually authentic scenarios while also scaffolding instruction to help students move beyond their current skill and knowledge base. Although there are many advantages of using multimedia case-based learning, there are also many challenges associated with designing technology-enhanced case studies for constructivist learning. The research described herein presents the advantages and challenges that emerged from three unique learning environments in health professional education programs. In each of these environments, a multimedia educational tool (named the multimedia case-based learning sports injury assessment educational tool) was designed to engage students in authentic sport injury case scenarios. Feedback was gathered from multiple stakeholders in each learning context and used to explore the effectiveness of this technology-enhanced pedagogical approach.

Abstract:

Purpose Using multimedia and print storybooks, the purpose of this paper is to compare preschool children’s reading engagement with and without adult support. Design/methodology/approach A within-subject design is used to explore the effects of multimedia stories in supporting preschool children’s story comprehension and reading enjoyment. A total of 24 children aged five to six years old from a local preschool in Taiwan participated in the experiments. Findings A statistical analysis revealed the (non)differences in story comprehension between multimedia and print storybooks, with and without adult support. A content analysis revealed several important themes affecting children’s reading enjoyment. These included multimedia elements (particularly motion and sound effects), haptic perception and the pause function. Research limitations/implications Native Chinese speaking children participated in one-to-one sessions in Taiwan. To ascertain the generalizability of the findings presented in this study, further research is encouraged in other cultural contexts and settings. Practical implications The paper provides insights into how multimedia and interactive features affect and enhance children’s enjoyment. Recommendations are made to assist library professionals to incorporate digital media into children’s programs. Originality/value Children’s reading motivation and engagement are often linked with improved reading attainments. This study elicited a range of perspectives and themes relating to what the children themselves felt influenced their enjoyment when reading print or multimedia storybooks. Findings were analyzed in a theoretical framework of facets of engagement.

Abstract:

Purpose – The overwhelming speed and scale of digital media production greatly outpace conventional indexing methods by humans. The management of Big Data for e-library speech resources requires an automated metadata solution. The paper aims to discuss these issues. Design/methodology/approach – A conceptual model called semantic ontologies for multimedia indexing (SOMI) allows for assembly of the speech objects, encapsulation of semantic associations between phonic units and the definition of indexing techniques designed to invoke and maximize the semantic ontologies for indexing. A literature review and architectural overview are followed by evaluation techniques and a conclusion. Findings – This approach is only possible because of recent innovations in automated speech recognition. The introduction of semantic keyword spotting allows for indexing models that disambiguate and prioritize meaning using probability algorithms within a word confusion network. By the use of AI error-training procedures, optimization is sought for each index item. Research limitations/implications – Validation and implementation of this approach within the field of digital libraries still remain under development, but rapid developments in technology and research show rich conceptual promise for automated speech indexing. Practical implications – The SOMI process has been preliminarily tested, showing that hybrid semantic-ontological approaches produce better accuracy than semantic automation alone. Social implications – Even as testing proceeds on recorded conference talks at the University of Tebessa (Algeria), other digital archives can look toward similar indexing. This will mean greater access to sound file metadata. Originality/value – Huge masses of spoken data, unmanageable for a human indexer, can prospectively find semantically sorted and prioritized indexing – not transcription, but generated metadata – automatically, quickly and accurately.

Abstract:

Rain Classroom, a mobile learning technology developed in China, has received great popularity. Research into its acceptance and effectiveness, however, remains sparse. Through research instruments, i.e. a questionnaire adapted from the Technology Acceptance Model (TAM), a semi-structured interview and linguistics knowledge tests, both quantitative and qualitative data were obtained to test research hypotheses. It was concluded that (1) Rain Classroom possesses significantly higher acceptance than traditional multimedia projecting systems in terms of performance expectancy, effort expectancy, social influence, facilitating conditions, and attitude at the significance level .05; and (2) Rain Classroom contributes to significantly higher linguistics knowledge gain than traditional multimedia projecting systems at the significance level .05. Future research could aim to improve and enhance the functions of Rain Classroom in order to pursue higher acceptance and effectiveness. Cross-disciplinary research could also be conducted to test its acceptance and effectiveness.

Abstract:

Getting requirements right is considered the most important and difficult part of the software development process. As organizations and stakeholders become more globally distributed, getting requirements right will pose a greater challenge. Today, organizations are offered a sophisticated array of multimedia meeting systems with video, audio and computer support for remotely specifying requirements. In the context of present day’s global workforce scenario, distributed requirements engineering is now being explored by researchers as well as industry to build an understanding of the dynamics of this highly interactive phase in a globally distributed context. Accordingly, this paper addresses the timely need of reviewing the literature on globally distributed requirements engineering. Findings highlight paucity of literature in this area. Additionally, the paper presents an innovative approach to globally distributed requirements engineering by reviewing the literature on the applicability of agile development approach in a globally distributed setting. Contributing to academic and practitioner literature, the author discusses emerging directions for future research in this area.

Abstract:

In this paper, we provide a holistic survey of multimedia content protection applications in which blockchain technology is being used. A taxonomy is developed to classify these applications with reference to the technical aspects of blockchain technology, content protection techniques, namely, encryption, digital rights management, digital watermarking and fingerprinting (or transaction tracking), and performance criteria. The study of the literature reveals that there is currently no complete and systematic taxonomy dedicated to blockchain-based copyright protection applications. Moreover, the number of successfully developed blockchain-based content protection systems is very low. This points towards a research gap. To fill this gap, we propose a taxonomy that integrates technical aspects and application knowledge and can guide the researchers towards the development of blockchain-based multimedia copyright protection systems. Furthermore, the paper discusses some technical challenges and outlines future research directions.
