Conjunctions are particularly difficult to parse in tra- ditional, phra.se-based gramniars. This paper shows how a different representation, not b.xsed on tree structures, markedly improves the parsing problem for conjunctions. It modifies the union of phra.se marker model proposed by GoodalI [19811, where conjllnction is considered as tile lin- earization of a three-dimensional union of a non-tree I),'med phrase marker representation. A PItOLOG grantm~tr for con- junctions using this new approach is given. It is far simpler and more transparent than a recent phr~e-b~qed extra- position parser conjunctions by Dahl and McCord [1984]. Unlike the Dahl and McCor, I or ATN SYSCONJ appr~ach, no special trail machinery i.~ needed for conjunction, be- yond that required for analyzing simple senten...
