    Lemmatized searches (BETA version)

    We are pleased to release a new feature of the TLG search engine, i.e. lemmatized searches. The new feature is still work in progress and is released for testing purposes.

    The TLG Lemmatization Project
    Work on lemmatization began in 2003 and benefited from access to software known as Morpheus developed by the Perseus Project. Morpheus was designed to deal effectively with a relatively narrow, well-documented cross section of the Greek language, i.e. the classical canon, meaning Epic and Attic Greek with some Doric, Ionic, and Koine forms. The TLG corpus encompasses the totality of Greek literature, including Early Modern Greek, and Byzantine texts. As a result, lemmatization of the TLG corpus required a different philosophy and a significantly more complex architecture, which combines lexical and morphological databases, and extensive programming in order to increase parses and achieve higher and more accurate form recognition.

    At the time of its first release in December 2006, the TLG lemmatizer recognized approximately 88% of the unique wordforms in the TLG corpus.
    We welcome suggestions and feedback from our users.
