Surface Realization

As mentioned above, the tree adjoining grammars developed by Talaris associate with each natural language expression not only a syntactic tree but also a semantic representation. In addition, because these grammars are unification based, they can be used either to derive a semantic representation from a sentence (analysis) or to generate a sentence from a semantic representation (generation). We are actively exploring how the grammars we develop, can be used to support data-to-text generation. After having developed several sentence generation algorithms (GenI, RTGen and D-RTGen) ([57] , [54] , [56] , [53] ), we are currently investigating: how to further optimise them; how to use them to verbalise knowledge bases and queries on knowledge bases; and how to evaluate their output.
