Periphraser

Periphraser is a tool for storing and presenting knowledge base of conventionalized periphrastic nominal expressions (i.e. phrases headed by a noun) together with their textually attested realizations. For instance, the database entry for the phrase Robert Lewandowski in the refered below demo for Polish will include the phrase the Polish international while pediatrics will be featured as medical care for children.
