Construct the lattice for the sentence
(“Everyone works for IBM”). Remember to include every kind of query that unifies with the sentence. -
Assume that indexes each sentence under every node in its subsumption lattice. Explain how should work when some of these sentences contain variables; use as examples the sentences in (a) and (b) and the query
