概率分析策略

Probabilistic Parsing Strategies

Mark-Jan Nederhof, Giorgio Satta

摘要:

我们提出了新的结果之间的关系,纯粹的符号上下文无关的分析策略和它们的概率对应部分。这样的分析策略被看作是从语法的下推设备的建设。我们证明了概率分布的保持在两个条件下是可能的,即正确前缀性质和强预测性质。这些结果概括了现有的结果在文献中,通过考虑分析策略孤立地获得。从我们的一般结果,我们也得到负面的结果,所谓的广义LR分析。

英文摘要:

We present new results on the relation between purely symbolic context-free parsing strategies and their probabilistic counter-parts. Such parsing strategies are seen as constructions of push-down devices from grammars. We show that preservation of probability distribution is possible under two conditions, viz. the correct-prefix property and the property of strong predictiveness. These results generalize existing results in the literature that were obtained by considering parsing strategies in isolation. From our general results we also derive negative results on so-called generalized LR parsing.
