语类加标与特征参数理论

Category Labeling and Feature Parametric Theory

在解释性结构语言学框架下,加标理论旨在根据合并中心语及其(扩展)投射,以结构核查程序确认语类特征标签,因此加标算法(LA)具有跨范畴的概括性和语义接口解释的指向性。加标理论的本质是实现句法范畴化的语类加标。特征参数理论确立特征层级,该理论与加标理论的互动成为最简方案研究的焦点问题。文章结合特征经济(FE)和输入概括(IG)分析语类加标以及功能中心语的参数特征解释效应,明晰了加标理论与语类特征会对窄式句法(NS)的输出表征产生解释效应和过滤效应并确立逻辑式(LF)无歧义解释。语类特征可统一界定为词汇和功能语类携带的解释特征。基于此,语类特征及其组合确定参数层级(语序、词汇结构、话语构型等)和参数变异。解释特征可涵盖合并触发特征和语段边界特征。加标贯穿于推导、表征和语类投射。结合聚合参数理论以及参数特征进一步论证加标程序及特征解释有助于解决投射问题、结构依存问题,确立语义解释规则和范畴化,而通过整合词库、特征经济和计算经济原则来深入分析微观参数理论是推进结构微观描写的优选方法。

Within the framework of interpretative structural linguistics,labeling theory with checking procedure aims to identify categorial features based on merged head and its(extended)projection,and so labeling algorithm(LA)has the property of cross-category generalization and semantic interface directionality.The nature of labeling theory is the categorial labeling for realizing syntactic categorization.The feature parametric theory establishes feature hierarchies,and its interaction with labeling theory is the focus of minimalist program research.This article analyzes the interpretative effects of categorial labeling and the feature parameters of functional heads with reference to feature economy(EC)and input generalization(IG).And it is further made explicit that labeling theory and categorial features can produce interpretive and filtering effects on the output representations generated by narrow syntax(NS)and establish an interpretive model for ambiguous logical form(LF).Categorial features can be uniformly construed as interpretive features carried by lexical and functional categories.In light of this,categorial features and their combination can specify the parametric hierarchies(word order,lexical structures and discourse configurations,etc.)and parametric variation.Interpretive features can encompass merge triggering features and phase edge features.Labeling is implemented throughout the derivations,representations and categorial projections.To illustrate labeling procedure and feature interpretations with bundling parametric theory and parametric features will contribute to solving projection problem and structural dependency,establishing semantic interpretative rules and categorization.Moreover,it is one optimal approach to investigate microparametric theory by integrating lexicon,feature economy and computational economy for promoting microstructural descriptions.
