- Start with a small set of seed patterns and seed tuples
- e.g. seed pattern: /* has a hub at */
- seed tuple: Ryanair - Charleroi
- Search for the terms in the seed tuple, within a corpus of documents
- Use the search results to extract new patterns
- /[ORGANISATION], which uses [LOCATION] as a hub/
- consider context before, between and after the 2 entities
- Search for additional tuples using the new patterns (to grow set of tuples)
