Frames and Overflows in Rights Expression Languages

Gary J. Hausman 6 December 2006 (has links)
This paper analyzes the visions, schemas, and vocabularies of prominent rights expression languages, including Creative Commons, METS, ODRL, and MPEG-21. The paper extends Michel Callon’s sociological insight that all forms of human agency are multiple and diverse. Callon argues, in the context of economic sociology, that one must constantly decide between a strategy emphasizing “framing” as the norm with “overflows” treated as leaks, or conversely a strategy accepting “overflows” as the norm with “framing” as inherently imperfect. Callon’s categories are extended, through a modeling exercise, to the classification of current metadata schemes. The analysis suggests that metadata developers should explore what semantic choices and strictures are left out of metadata schemes, as well as those that are included. Such a thought exercise is especially useful in distinguishing areas suited for XML rights markup extensions.

A method for mapping XML-based specifications between development methodologies

Huang, Fei 17 April 2009
The Unified Modeling Language (UML) is widely used by software engineers as the basis of analysis and design in software development. However, UML ignores human factors in the course of software development because of its strong emphasis on the internal structure and functionality of the application. This thesis presents a method of mapping human-computer interaction (HCI) requirement specifications generated by usability engineering (UE) methodologies (e.g. Putting Usability First (PUF)) into UML specifications. These two sets of requirement specification are specified, using Extensible Markup Language (XML) so that HCI requirement specifications can be integrated into UML ones. A Mapping Tool was developed to facilitate the creation of mappings between PUF XML tags and XMI tags. The Mapping Tool was used to create mappings between PUF and UML requirement specifications. This mapping process and its outputs were evaluated to demonstrate that the tool worked. The results of the evaluation show that the HCI requirement specification represented by the PUF XML tags can improve the UML specification by adding them into the XMI tags.

Predicting Community Preference of Comments on the Social Web

Hsu, Chiao-Fang 2009 December 1900 (has links)
Large-scale socially-generated metadata is one of the key features driving the growth and success of the emerging Social Web. Recently there have been many research efforts to study the quality of this metadata - like user-contributed tags, comments, and ratings - and its potential impact on new opportunities for intelligent information access. However, much existing research relies on quality assessments made by human experts external to a Social Web community. In the present study, we are interested in understanding how an online community itself perceives the relative quality of its own user-contributed content, which has important implications for the successful selfregulation and growth of the Social Web in the presence of increasing spam and a flood of Social Web metadata. We propose and evaluate a machine learning-based approach for ranking comments on the Social Web based on the community's expressed preferences, which can be used to promote high-quality comments and filter out low-quality comments. We study several factors impacting community preference, including the contributor's reputation and community activity level, as well as the complexity and richness of the comment. Through experiments, we find that the proposed approach results in significant improvement in ranking quality versus alternative approaches.

Metadatadriven transformering mellan datamodeller

Åhlfeldt, Fredrik January 2000 (has links)
<p>För att flytta information från en databas till ett datalager används det idag olika tekniker. Existerande transformeringstekniker baseras på att en applikation hanterar detta. Detta examensarbete går ut på att skapa och undersöka en metod som istället genomför transformeringen i en databas. Denna transformering är metadatadriven, eftersom metadata är den information om data som krävs för att en transformering ska vara möjlig. Arbetet bygger därför på en metadatastudie som behandlar representation och struktur av metadata. Målet med arbetet är att få fram en så generell transformeringsmetod som möjligt och metoden går ut på att transformera data från en normaliserad databasstruktur till en denormaliserad datalagersstruktur.</p>

En utvärdering av verktygsstödet för den semantiska webben

Fredriksson, Pär January 2004 (has links)
<p>Då den webb som vi idag använder har växt snabbt har ett antal problem uppstått. Antalet tjänster är många och mängden information är stor. Den enorma informationsmängden gör att det är svårt att hitta relevant sådan vid sökningar. Om maskiner kunde hjälpa till med sökningen skulle problemet minska.</p><p>Den semantiska webben beskrivs som en förlängning av den nuvarande webben skapad för att låta maskiner kunna utnyttja den information som finns representerad på webben. För att kunna göra webben maskinläsbar krävs det att webben kodas med semantisk information. Detta kan göras av personer som författar webbsidor. För att detta ska kunna göras krävs det att det finns verktyg som tillåter att det görs, verktygen ska gärna kunna användas samtidigt som webbsida skapas. Denna studie har utvärderat hur de webbsidesredigeringsverktyg som används idag kan användas för att skapa semantisk uppmärkning. Studien går igenom ett antal verktyg ur olika kategorier och utvärderar det semantiska stödet dessa ger användaren. Utvärderingen görs med hjälp av kriterier som tagits fram genom att studera ett antal prototypverktyg för semantisk uppmärkning.</p><p>Resultatet av studien ger en indikation på att de verktyg som idag används inte är redo för att låta användaren skapa webbsidor märkta med semantisk information.</p>

Picnic - a platform for sharing pictures and socialize people

Putz, Daniel Robert January 2007 (has links)
<p>The internet itself is continuously changing. Since it was widely introduced, the users’ main focus has shifted from a communication tool, to a huge file sharing pool, to a marketing tool, to an information gathering and information reproducing tool.</p><p>Nowadays the way of sharing files needs to be reconsidered, because more and more private information is shared over the internet. The common file sharing applications are no longer appropriate for today’s purposes. Also the common way of socializing people is not up to date anymore.</p><p>Sharing files already implies a communication between users. But why do we not use the given information of shared data in order to socialize them? This thesis discusses the problematic domains of sharing images and socializing and introduces a tool named Picnic that has been conceived and implemented in order to overcome those problems.</p>

Considerations for IP-Based Range Architectures

Kovach, Bob 10 1900 (has links)
ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / In the past several years there has been a good amount of effort expended in migrating telemetry streams to IP-based infrastructure, especially in the area of ground-based transport. This has yielded a number of benefits, from leveraging the properties of IP transport to enable multicast transport, to the integration of the wide number of COTS equipment that also is IP-based, such as digital video encoder/decoders into range networks. This paper will provide a model for identifying areas to accelerate the integration of IP-based assets into the range infrastructure at the application level. In particular the integration of metadata between the telemetry and video application interfaces will be explored.
