A lexico-syntactic pattern is a string matching pattern that is based on text tokens and syntactic structure.

- A given linguistic marker (see, e.g., table 1) can occur in different contexts, some of which are definitions, and can be a clue for different semantic relations. Lexico-syntactic patterns aim at reducing this ambiguity by specifying more restricted contexts in which a definition is found, and, furthermore, in which one specific semantic relation is involved.
- Unlike (Hearst, 1992), we started the pattern design by analysing marker occurrences in our training corpus. We designed and tuned our lexico-syntactic patterns on this corpus, patterns dedicated to the extraction of definitions and specific relations: hypernymy and synonymy.
