A language independent Linearization Engine. OxyGen takes an input expression in the form of the Abstract Meaning Representation (AMR) developed for the Nitrogen generator and works out a linear ordering for the specified lexical items. The output of the linearization process is a word lattice. A language (oxyL) is specified for writing linearization rules. The linearization process is hybrid, combining symbolic and statistical information. The system has been used in machine translation efforts such as ChinMT and others from Bonnie Dorr.
