Finding emotional-laden resources on the World Wide Web
Some content in multimedia resources can depict or evoke certain emotions in users. The aim of Emotional Information Retrieval (EmIR) and of our research is to identify knowledge about emotional-laden documents and to use these findings in a new kind of World Wide Web information service that allows users to search and browse by emotion. Our prototype, called Media EMOtion SEarch (MEMOSE), is largely based on the results of research regarding emotive music pieces, images and videos. In order to index both evoked and depicted emotions in these three media types and to make them searchable, we work with a controlled vocabulary, slide controls to adjust the emotions’ intensities, and broad folksonomies to identify and separate the correct resource-specific emotions. This separation of so-called power tags is based on a tag distribution which follows either an inverse power law (only one emotion was recognized) or an inverse-logistical shape (two or three emotions were recognized). Both distributions are well known in information science. MEMOSE consists of a tool for tagging basic emotions with the help of slide controls, a processing device to separate power tags, a retrieval component consisting of a search interface (for any topic in combination with one or more emotions) and a results screen. The latter shows two separately ranked lists of items for each media type (depicted and felt emotions), displaying thumbnails of resources, ranked by the mean values of intensity. In the evaluation of the MEMOSE prototype, study participants described our EmIR system as an enjoyable Web 2.0 service
Building heritage collections using games on social networks
Includes abstract.Includes bibliographical references.An application on a social network may provide a means to avoid the cost, decrease time and increase scale of operation of heritage preservation by motivating users to supply and process the data. This project uses a Facebook application for the purpose of gathering heritage pictures and useful metadata and tagging. The application was written in Python using the Django Web Framework, connected to Facebook using the Graph API and was hosted on an Amazon Elastic Compute Cloud instance. Motivation techniques to promote user participation were investigated
Combining Metadata, Inferred Similarity of Content, and Human Interpretation for Managing and Listening to Music Collections
Music services, media players and managers provide support for content
classification and access based on filtering metadata values, statistics of access and user
ratings. This approach fails to capture characteristics of mood and personal history that
are often the deciding factors when creating personal playlists and collections in music.
This dissertation work presents MusicWiz, a music management environment that
combines traditional metadata with spatial hypertext-based expression and automatically
extracted characteristics of music to generate personalized associations among songs.
MusicWiz’s similarity inference engine combines the personal expression in the
workspace with assessments of similarity based on the artists, other metadata, lyrics and
the audio signal to make suggestions and to generate playlists. An evaluation of
MusicWiz with and without the workspace and suggestion capabilities showed
significant differences for organizing and playlist creation tasks. The workspace features
were more valuable for organizing tasks, while the suggestion features had more value
for playlist creation activities
