Using Visual Features to Improve Tag Suggestions in Image Sharing Sites

Reply

Social media sharing sites such as Flickr or YouTube have become immensely popular. Besides sharing actual content, users also share annotations describing or classifying the contents they publish. Although tagging is easy, annotation still is a laborious task that can be made easier by suggesting meaningful additional tags to the user automatically. In this position paper we propose a system architecture and process for supporting annotation by tag suggestion to increase the quality and quantity of social annotations. The goal is not to tag previously untagged images in a completely automatic way, but instead to extend the amount and completeness of annotations by supporting the user in the process of adding further tags.

Learner-Generated Annotation of Learning Resources – Lessons from Experiments on Tagging

Reply

The importance of comprehensive annotations for learning resources is widely recognized. However, it is often unclear how these annotations should be created. A promising solution might be that learners annotate learning resources during execution of learning processes. This paper examines tagging as a learner-driven approach that can be used to get annotations on a collaborative level. The characteristics of learner-generated annotations in learning scenarios and the applicability of these annotations to describe learning resources are investigated. As empirical grounding, the results of three independent experiments are presented in order to inform decisions concerning the establishment of stitutionalized settings deploying tagging approaches.

A Multimedia Annotation Vocabulary for Semantically Supported Multimedia Presentation Generation

Reply

As the annotation of media resources becomes increasingly viable with intuitive tools and semi-automatic extraction of information, the need for a common annotation vocabulary becomes ever stronger. Such a vocabulary needs to be able to provide enough information to a computer system to allow for media retrieval, adaptation and presentation. On the other hand, complexity will inhibit uptake on the Semantic Web, where simplicity seems to be the key to success. I present my research in building an automated multimedia presentation system and from this experience I outline a vocabulary which covers the needs of retrieval, adaptation and presentation of media by intelligent systems.
