An Annotation Scheme for Information Status in Dialogue
Malvina Nissim, Shipra Dingare, Jean Carletta, Mark J. Steedman · 2004
We present an annotation scheme for information status (IS) in dialogue, and validate it on three Switchboard dialogues.We show that our scheme has good reproducibility, and compare it with previous attempts to code IS and related features.We eventually apply the scheme to 147 dialogues, thus producing a corpus that contains nearly 70,000 NPs annotated for IS and over 15,000 coreference links.* This work was supported by a Scottish Enterprise Edinburgh-Stanford Link Grant (265000-3102-R36766). 1 We follow (Prince, 1992) in using " old" rather than "given" to refer to "not-new" information, but regard the two as identical.For the sake of space we do not discuss terminology.For an overview see (Vallduví, 1992;Steedman, 2000).2 This type corresponds to Prince's (1981; 1992) inferrables.
