Exploring External Links in Twitter
Due to the space limitation of a Twitter message, the role of external links grows immense. External links can provide additional information, back up a statement, enliven a discussion, etc. The aim of this work is to explore the intended use of external links in the context of Twitter and how they can be considered in order to improve the performance of state-of-the-art topic detection and tracking approaches.
Visualization of Large Video Collections
Existing video collections are usually visualized using simple list view based on coarse categories. Such collections easily become unbearable with increasing size of the dataset. The goal of this work is to provide an alternative to the conventional list view of large video collections that allows for an intuitive and fast browse and retrieval. Next to user-provided metadata, this work will explore the feasibility of content-based features in this context.
