Annotation

What is annotation exactly? What types of annotation are there? And which type would fit my project? My first step is to just ‘google’ annotation and find an understandable and good working definition for myself. Annotation is a critical or explanatory (body of) note(s) added to any form of text. An example that immediately comes into my mind is a highlighted sentence in a summary or book. Wolfe and Neuwirth (2004) have identified four functions of annotation in their article. Annotation can be used to:
1)     Facilitate reading and later writing
2)     Eavesdrop on insights of other readers
3)     Provide feedback for the writer
4)     Call attention to topics and important passages
The functionalities of annotation are very useful in the process from scientific article to CDSS app. The goal of the annotation step in this process is to filter out the most important information of the article and then turn this into a flowchart. To be able to do this, medical specialists will have to work together to annotate scientific articles. By collaborative annotating they can call attention to important topics and passages and facilitate reading for specialists who will read the article after them. They can help each other and make use of each other’s insights.
Annotating used to be done on paper, but now it is also possible to this on a web resource: web-based annotating. A user needs web annotation system to add, modify, and remove information from a web resource. This system makes it possible to annotate in a separate layer so the original source is not modified. Web-annotating has several applications. For instance, web-annotating can be used to rate a web resource or to improve the content of a source. A third option is to use web-annotating for collaborative annotating since it is easy to share (annotated) documents with the annotation software. Therefore, web-based annotating can be a helpful tool to support the collaborative annotating process by the medical specialists.
As a next step, I am going to investigate and compare different web-based annotation system. This comparison will be, among others, based on the user-friendliness and different features, like the option to highlight text, make different types of notes, and the type of documents that can be annotated.
