However, existing data caps in cellular network contracts and limitations in their upload capabilities restrict the adoption of mobile video broadcasting services. Additionally, the quality of those video streams is often reduced by the lack of skills of recording users and the technical limitations of the video capturing devices. Our research focuses on large-scale events that attract dozens of users to record video in parallel. In many cases, available network infrastructure is not capable to upload all video streams in parallel. To make decisions on how to appropriately transmit those video streams, a suitable monitoring of the video generation process is required. For this scenario, a measurement framework is proposed that allows Internet-scale mobile broadcasting services to deliver samples in an optimized way. Our framework architecture analyzes three zones for effectively monitoring user-generated video. Besides classical Quality of Service metrics on the network state, video quality indicators and additional auxiliary sensor information is gathered. Aim of this framework is an efficient coordination of devices and their uploads based on the currently observed system state.","PeriodicalId":365687,"journal":{"name":"WISMM '14","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117309148","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}

However, existing music search engines are usually not convenient or too complicated for users to create multidimensional music queries, leading to the intention gap between users' music information needs and the input queries. In this paper, we present a novel content-based music search engine, the Intelligent & Interactive Multidimensional mUsic Search Engine (i2MUSE), which enables users to input music queries with multiple dimensions efficiently and effectively. Six musical dimensions, including tempo, beat strength, genre, mood, instrument, and vocal, are explored in this study. Users can begin a query from any dimension and interact with the system to organize the query. Once the parameters of some dimensions have been set, i2MUSE is able to intelligently highlight a suggested parameter and gray out an un-suggested parameter for every other dimension, helping users express their music intentions and avoid parameter conflicts in the query. In addition, i2MUSE provides a real-time illustration of the percentage of matched tracks in the database. Users can also set the relative weight of each specified dimension. We have conducted a pilot user study with 30 subjects and validated the effectiveness and usability of i2MUSE.","PeriodicalId":365687,"journal":{"name":"WISMM '14","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121383196","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}

People share their experiences with their friends and relatives with the help of multimedia such as image, video, text, etc. The amount of such shared multimedia is also growing likewise. The large amount of multimedia data on OSNs contains in it a snapshot of user's life. This social network data can be crawled to build stories about individuals. However, the information needed for a story, such as events and pictures, is not fully available on user's own profile. While part of this information can be retrieved from user's own timeline, a large amount of event and multimedia information is only available on friend's profiles. As the number of friends can be very large, in this work we focus on identifying subset of friends for enriching the story data. In this paper we explore social relationships from multimedia perspective and propose a framework to build stories using information from multiple-profiles. To the best of our knowledge, this is the first work on building stories using multiple OSN profiles. The experimental results show that with the proposed method we get more information (events, locations, and photos) about the individuals in comparison to the traditional methods that rely on user's own profile alone.","PeriodicalId":365687,"journal":{"name":"WISMM '14","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116358892","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}

Our motivation of this work is very intuitive: we want to evaluate student performance of multimodal learning over the Internet. We are developing a system for student performance evaluation which can automatically collect student-generated multimedia data during online multimodal learning and analyze student performance. As our initial step, we propose to make use of a vector space model to process student-generated multimodal data, aiming at evaluating student performance by exploring all annotation information. In particular, the area of a study material is represented as a 2-dimensional grid and predefined attributes form an attribute space. Then, annotations generated by students are mapped to a 3-dimensional indicator matrix, 2-dimensions corresponding to object positions in the grid of the study material and a third dimension recording attributes of objects. Then, recall, precision and Jaccard index are used as metrics to evaluate student performance, given the teacher's analysis as the ground truth. We applied our scheme to real datasets generated by students and teachers in two schools. The results are encouraging and confirm the effectiveness of the proposed approach to student performance evaluation in multimodal learning.","PeriodicalId":365687,"journal":{"name":"WISMM '14","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128164586","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}
