This thesis compares different vector space projection techniques for creating two–dimensional maps out of text document collections. I describe the process from raw text information to similarity maps and implemented a working prototype.

Document mapping is a recently developed sub–discipline of interactive information visualization. The core idea is to combine traditional cartographic techniques with today’s possibilities for automated analysis of text data in an interactive interface. It is hypothesized that this form of presentation for text documents facilitates a quick perception of the similarity of their contents. Hence, it can constitute a valuable addition to traditional browsing and search methods.
