FooCA: web information retrieval with formal concept analysis. ... A generalization of Web search results is conducted, leading to an FCA-based introduction of FooCA. FooCA is an application in the field of Conceptual Knowledge Processing and supports the idea of a holistic representation of Web Information Retrieval. FooCA operates on Web search results, using the itemset consisting of the title, a short description, and the URL to build a formal context and an appropriate concept lattice. In order to generate a well-arranged concept lattice, using line diagrams to retrieve and analyze the data, it is shown step by step how the prior context can be iteratively explored and enhanced. Besides serving as a tool for holistic data exploration, FooCA also enables the regular user to learn step by step how to run new, optimized search queries for his personal information needs on the Web.
