Abstract The Papuan language Mian allows us to refine the typology of nominal classification. Mian has two candidate classification systems, differing completely in their formal realization but overlapping considerably in their semantics. To determine whether to analyse Mian as a single system or concurrent systems we adopt a canonical approach. Our criteria – orthogonality of the systems (we give a precise measure), semantic compositionality, morphosyntactic alignment, distribution across parts of speech, exponence, and interaction with other features – point mainly to an analysis as concurrent systems. We thus improve our analysis of Mian and make progress with the typology of nominal classification.

单一系统与并发系统：棉棉的名义分类

摘要巴布亚语Mian使我们能够完善名词分类的类型。Mian有两个候选分类系统，它们的形式实现完全不同，但语义上却有很多重叠。为了确定是将Mian分析为单个系统还是并发系统，我们采用规范方法。我们的标准-系统的正交性（我们给出精确的度量），语义组成，句法句法对齐，语音各部分之间的分布，指数以及与其他功能的交互-主要指向作为并发系统的分析。因此，我们改善了对棉棉的分析，并在名词分类的类型学上取得了进步。
