Transfer Semantics for the Clear Parser

ABSTRACT. Transfer semantics uses a rewriting (or transfer) system to map syntactic parses onto semantic representations [4, 5]. This form of semantic mapping was used to build broad coverage semantic text indexes at Powerset, and has been used in various other settings such as question answering for intelligence analysts and medical QA. It has been used for English, German [14] and Japanese [13]. However, in all these cases the transfer semantics has been applied to the output of just one kind of parser: LFG functional structures created by the XLE parser [6]. This paper describes the adaptation of transfer semantics to apply to the output of the Clear dependency parser [2].
