A lexico-syntactic pattern is a string matching pattern that is based on text tokens and syntactic structure.
- AKA: Lexico-Syntactic String Matching Pattern, Lexico-Syntactic String Pattern.
- Context:
- It can be a Regular String Expression Pattern.
- It is restricted to a single language.
- Example(s):
- any Lexical Pattern.
- any Syntactic Pattern.
- See: Information Extraction Pattern, Hearst Pattern.

- 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.
