Tags are useful text-based labels that encode semantic information about music (instrumentation, genres, emotions, geographic origins). While there are a number of ways to collect and generate tags, there is generally a data sparsity problem in which very few songs and artists have been accurately annotated with a sufficiently large set of relevant tags. We explore the idea of tag propagation t...

Zur Verortung der explorativen Empiriephase und ihrer Ergebnisse innerhalb des Projektes „Entwicklung von Gestaltungsanforderungen bei vernetzten Systemen“ soll der Projektverlauf kurz skizziert werden. Zur Vorbereitung diente zunächst eine ausführliche Analyse der Literatur zu vernetzten Systemen. Dazu zählten Beschreibungen im Betrieb befindlicher Systeme, Literatur zu aktuellen und potentiel...

Text-to-speech synthesizers must process text, and therefore require some knowledge of text structure. While many TTS systems allow for user control by means of ad hoc ‘escape sequences’, there remains to date no adequate and generally agreed upon system-independent standard for marking up text for the purposes of synthesis. The present paper is a collaborative effort between two speech groups ...

This paper presents a usability analysis of RECOLED, a shared document editor which supports recording of audio communication in remote collaborative writing sessions, and transparent monitoring of interactions, such as editing, gesturing and scrolling. The editor has been designed so that the collaboration results in the production of a multimedia document history which enriches the final prod...

In a recommender system where users rate items we predict the rating of items users have not rated. We define a rating graph containing users and items as vertices and ratings as weighted edges. We extend the work of [1] that uses the resistance distance on the bipartite rating graph incorporating negative edge weights into the calculation of the resistance distance. This algorithm is then comp...

This study adapts existing tools (Jigsaw and a text editor) to support multiple input devices, which were then used in a co-located collaborative intelligence analysis study conducted on a large, high-resolution display. Exploring the sensemaking process and user roles in pairs of analysts, the two-hour study used a fictional data set composed of 50 short textual documents that contained a terr...

In recent years anti-spam filters have become necessary tools for Internet service providers to face up to the continuously growing spam phenomenon. Current server-side anti-spam filters are made up of several modules aimed at detecting different features of spam e-mails. In particular, text categorisation techniques have been investigated by researchers for the design of modules for the analys...
