Methods for Web 2.0 Data

Developing large scale technologies, e.g., mobile communication systems, requests the study of peoples acceptance and risk sense. For such research topics interdisciplinary collaboration is essential. In cooperation with textlinguists, we focus on the investigation of grammatically non-standard Web comments and their ability to serve as source for automatic opinion detection in terms of acceptance research. Three steps are included in our research:

• The aquistion of Web comments by means of Web Search/Focused Crawling Algorithms,
• the detection/classification of Web comments and their meta data in Web pages, and
• the adaption of natural language processing methods, e.g., POS Tagging to Web comment language.

The figure above shows the interaction between the different methods.
