In analogy to the example in Figure 7.4, can you model the relations for a word or set of words in WordNet (http://wordnet.princeton.edu/) in a similar manner using FCA? How can you derive a formal context? If you start with a word and collect all related words, where do you stop collecting? How do you determine the formal attributes? Can you see a way of how the process of generating concept lattices from WordNet could be automated?
