We present a mobile touchable application for online topic graph extraction and exploration of web content. The system has been imple- mented for operation on an iPad. The topic graph is constructed from N web snippets which are determined by a standard search en- gine. We consider the extraction of a topic graph as a specific empirical collocation ex- traction task where collocations are extracted between chunks. Our measure of association strength is based on the pointwise mutual in- formation between chunk pairs which explic- itly takes their distance into account. An ini- tial user evaluation shows that this system is especially helpful for finding new interesting information on topics about which the user has only a vague idea or even no idea at all.
