This study shows that the structure of openly available social media records, such as Twitter, offers a possibility for building a unique dynamic signature of urban neighborhood function,...

This paper describes a method for using supervised learning to generate sheet music from audio files of single instrument melodies. Support Vector Machines were used to detect the presence of up to 88 notes with one-versus-all classification. We also outline preliminary steps toward transcribing a whole melody by using a sliding window to detect note changes in an audio sample.

World-Wide Web technologies have rapidly transformed the entire design, development and implementation process for all types of Decision Support Systems. In particular, Web technologies have provided a new media for sharing information about decision support and a new means of delivering decision support capabilities. For DSS developers, the big leap forward is to use the “Web as computer”.

This paper proposes an integrated approach to discriminate news reporting from everything else in broadcast news data based on both audio and visual information. The separation of news reporting segments from others not only can provide useful indices for video streams but also serves as a pre-processing step for tasks such as speaker identi cation and speech recognition so that only speech seg...
