The forum paradigm is adopted by the most followed websites, such as social networks and blogs. The effectiveness of discussion forums as information source, i.e., the capability to satisfy their users' information needs, depends on their information richness first, but also on how their are organized and effectively moderated. Forums organized and moderated by topics of discussion tend to host messages on related subjects and, overall, provide a classification of message threads which eases information search. In this paper we propose a semi-automatic approach to detect topics of discussion in a forum and to enhance its organization by providing a hierarchical topic-driven navigation view on its messages. We adopt Information Retrieval (IR) techniques, such as topic modeling, and formal concept analysis (FCA) to identify discussion topics and to provide a hierarchical topic-centered view on messages. We tested the validity of our approach on four forums of the e-learning platform of an Italian distance-learning university which provides around 20 moderated and unmoderated main forums followed actively by almost 5000 users, including students and teachers, each year. We validated the topics identification and messages to topics allocation process with a specific empirical experiment obtaining promising results.","PeriodicalId":297233,"journal":{"name":"2013 IEEE Global Engineering Education Conference (EDUCON)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126118826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of a plurality of cheaper and more powerful devices, having the ability to play, create, and transmit video content, has led to a dramatic increase in the multimedia content distribution, especially for engineering educational purposes on both wireline (e.g., cable) and wireless networks. Also, the reduction of cost of digital video cameras along with the development of user-generated content video sites (e.g., YouTube™) stimulated a new user-generated video content sector and made very strong demands for the high-quality and low-delay video communication, especially for online education courses and lectures in the engineering field. In addition, much of the attention in the field of video/multimedia adaptation is currently directed to the SVC, which is an extension of the H.264/AVC video standard. A major requirement for the SVC is to enable encoding of a high-quality video stream that contains one or more subset video streams, each of which can have for example, various temporal and spatial resolutions (i.e., QCIF, CIF, 720p, 1080p) to be presented on heterogeneous user devices, such as mobile/cellular phones, laptops, personal computers, TV sets, and the like. In this work, we focus on online multimedia engineering education by employing Region-of-Interest SVC, thereby enabling to provide an ultimate solution for streaming educational multimedia content to a plurality of heterogeneous end-user devices.","PeriodicalId":297233,"journal":{"name":"2013 IEEE Global Engineering Education Conference (EDUCON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124746951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Tokyo University of Technology, role-play training has been carried out as a part of project management education. We have been developing an on-line group work training system named PROMASTER (Project Management Skills Training Environment) which can gather the behavior records of each learner to realize PBE (Profile Based Education). Also we have developed a software agent system, named BONAMI (agent system Based ON Aggregated Mentoring and expert Intelligence for project management), which plays the role of an adviser, and monitors the behavior of each learner, when necessary encouraging a learner to take the action. However BONAMI cannot suggest that a learner takes the proper procedures in a timely manner. In this paper, we propose an instruction method for providing advice or a hint in a timely manner. The proposed method is based on the principle that “the correct solution should be derived through the correct orderly manner”. In particular, the method is to extract the conversation patterns from the chat messages and then to compare them to model patterns. According to the result of analyzing the actual conversation patterns, the learners' acquired skill level was found to be positively correlated with the degree of the desirable patterns. This result suggests that the degree of desirable patterns might correspond to the correct orderly approach. Consequently the proposed method encourages learners to discuss in an orderly correct manner to arrive at a correct solution.","PeriodicalId":297233,"journal":{"name":"2013 IEEE Global Engineering Education Conference (EDUCON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131715250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
