Instead of page titles, Primal Fusion shows you the tags and concepts that are associated with your keywords, which you can use to refine or expand your search.  Strangely, you can’t really look at the results of your search and categorization from inside Primal Fusion. Instead, you click a button to create a Website with all the info (although this feature is a little unstable). In the future you’ll be able to create a document or an RSS feed instead. Semantic analysis of documents isn’t just complex as it creates an index much larger than the original document. That just wouldn’t work for the Web, so what Primal Fusion does is create a very compact semantic representation of what you’re thinking about, in real time. It then compares the semantic representation to the concepts it finds, dividing them into content that correlates with what you’re thinking about already and new topics. This is a very sophisticated system, but searches can be slow and with only a few sources and a basic interface, it’s very much a work in progress.
