  This paper presents a tool, TyDI, and methods experimented in the building of
a termino-ontology, i.e. a lexicalized ontology aimed at fine-grained
indexation for semantic search applications. TyDI provides facilities for
knowledge engineers and domain experts to efficiently collaborate to validate,
organize and conceptualize corpus extracted terms. A use case on biotechnology
patent search demonstrates TyDI's potential.
