位移演算

Displacement Calculus

Universitat Pompeu Fabra(庞培法布拉大学)

摘要:

Lambek演算以连接逻辑的形式为范畴语法提供了基础。但是自然语言的特征是依赖性,这种依赖性也可能是不连续的。本文介绍了Lambek演算的推广--位移演算,它在包含不连续性和包含不连续性的同时保持了Lambek演算良好的证明理论性质,并举例说明了它在语言学中的应用,证明了割消、子公式性质和可判定性

英文摘要:

The Lambek calculus provides a foundation for categorial grammar in the form of a logic of concatenation. But natural language is characterized by dependencies which may also be discontinuous. In this paper we introduce the displacement calculus, a generalization of Lambek calculus, which preserves its good proof-theoretic properties while embracing discontinuiity and subsuming it. We illustrate linguistic applications and prove Cut-elimination, the subformula property, and decidability
