Vieira和Poesio(2000年)提出了一种Definite Description(DD)解析算法，该算法结合了许多用于检测语篇新描述的启发式算法。这种检测器被纳入的动机是观察到，在平均语料库中超过50%的Definite描述(DD Vieira)是语篇新的(Poesio和Vieira，1998)，但是尽管在算法中包括非指代代词的检测器导致了精确度的明显提高，这些检测器带来的照应消解(相对于经典fi阳离子)的改善相当小。事实上，Ng和Cardie(2002a)对加入这种探测器的动机提出了质疑，报告没有改进，甚至性能更差。我们详细地重新审查了有关这个主题的文献，并提出了一个修订的算法，利用了Uryupina(2003)开发的改进的话语-新检测技术。
Vieira and Poesio (2000) proposed an algorithm for definite description ( DD ) resolution that incorporates a number of heuristics for detecting discourse-new descriptions. The inclusion of such detectors was motivated by the observation that more than 50% of definite descriptions ( DD s) in an average corpus are discourse new (Poesio and Vieira, 1998), but whereas the inclusion of detectors for non-anaphoric pronouns in algorithms such as Lap-pin and Leass’ (1994) leads to clear improvements in precision, the improvements in anaphoric DD resolution (as opposed to classification) brought about by the detectors were rather small. In fact, Ng and Cardie (2002a) challenged the motivation for the inclusion of such detectors, reporting no improvements, or even worse performance. We re-examine the literature on the topic in detail, and propose a revised algorithm, taking advantage of the improved discourse-new detection techniques developed by Uryupina (2003).
