MMSI aims at developing a cross-media analysis and monitoring platform that enables to measure and understand information life-cycle within a set of radio, tv, newspaper and web sources. MMSI allows to quickly build ad-hoc web applications that implements study according to customers needs. We here present MMSI Talk, a platform for quantitative and qualitative analysis of political talks. MMSI Talk is a web interface that allows a global monitoring of broadcasted political content over a set of french radio. MMSI Talk allows intuitive search through queries by media, named entities, political party and/or politician. It includes access to talks, cumulative measure of speech duration at the politician or political party level. Moreover MMSI Talk provides a set of statistical and visualization tools that allow an advance understanding of political communication strategies. We first describe the context and motivation of the MMSI Talk talk platform. We then describe the global architecture of the platform before presenting the user interface through several concrete use cases.","PeriodicalId":318758,"journal":{"name":"Proceedings of the 19th ACM international conference on Multimedia","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124810342","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}

We design a new tag query interface that allows users to input multiple tags with multiple levels of preference (denoted as an MTML query) by colorizing desired tags in a web-based tag cloud interface. When a user clicks and holds the left mouse button (or presses and holds his/her finger on a touch screen) on a desired tag, the color of the tag will change cyclically according to a color map (from dark blue to bright red), which represents the level of preference (from 0 to 1). In this way, the user can easily organize and check the query of multiple tags with multiple levels of preference through the colored tags. To effect the MTML content-based music retrieval, we introduce a probabilistic fusion model (denoted as GMFM), which consists of two mixture models, namely a Gaussian mixture model and a multinomial mixture model. GMFM can jointly model the auditory features and tag labels of a song. Two indexing methods and their corresponding matching methods, namely pseudo song-based matching and tag affinity-based matching, are incorporated into the pre-learned GMFM. We evaluate the proposed system on the MajorMiner and CAL-500 datasets. The experimental results demonstrate the effectiveness of GMFM and the potential of using MTML queries to search music from an untagged music database.","PeriodicalId":318758,"journal":{"name":"Proceedings of the 19th ACM international conference on Multimedia","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131546034","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}

Such systems are also prone to performance degradation due to undesired behavior in the event of drastic demand changes, such as view change and large-scale simultaneous viewer arrivals or departures. Therefore, it is crucial to localize undesired behavior inside the system and re-organize the streaming overlay structures accordingly. Doing this accurately for a large scale is even more challenging and it requires to capture all events effecting the data plan and control plan of the system. Moreover, to do this, we need to understand the desired behavior of the application first, which is defined by the dependency patterns of performance and configuration metadata at each participating peers. To assist that, we propose a learning framework that discovers metadata dependency patterns from the time series metadata and uses an online profiler to detect undesired behavior of the system during run-time. Such universal protocol also enables the prediction of large scale performance degradation due to irregular dependencies. Finally an adaptation is proposed that reallocates the resources and rearranges overlay structures to overcome the undesired behavior. In summary, our goal is to provide a universal session monitoring and management framework for complex multi-stream 3DTI environments to support large number of concurrent viewers. We consider the difficulty in overlay construction, collecting metadata, answering queries, learning patterns, detecting undesired behavior at the participating peers and finally overlay adaptation considering multi-stream dependencies.","PeriodicalId":318758,"journal":{"name":"Proceedings of the 19th ACM international conference on Multimedia","volume":"281 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131426079","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}
