Decide on a lexical relation R of interest, e.g.hyponymy/hypernymy.2. Gather a list of terms for which this relation is known to hold, e.g.hyponym (car, vehicle).This list can be found automatically using the patterns already learned or by bootstrapping from an existing lexicon or knowledge base.3. Find expressions in the corpus where these terms occur syntactically near one another.4. Find the commonalities and generalize the expressions in 3 to yield patterns that indicate the relation of interest.5. Once a new pattern has been identified, gather more instances of the target relation and go to step 3.
