TTR 不是词汇丰富度:语料变长时,它会系统性惩罚你

【锚点】本轮只钉一个判断:【TTR=V/N 不是跨长度比较的词汇丰富度指标;它把“语料规模”混进了“词汇多样性”。】 【显式】TTR 是类型数 V 除以词次 N。若语料从 1000 词扩到 2000 词,唯一词数通常不会翻倍。按 Heaps 律 V≈K·N^β,自然语言里 β 常在 0.5–0.8。取 β=0.6,N 翻倍时 V 只乘 2^0.6≈1.52,TTR 乘…

「同一门英语,同一个特征,差 47%」——语料库的「代表性」不是被发现的,是被决定的

【锚点】这一篇只钉一个判断:当你说「语料库显示 X」,你测的不是【语言】,是【你能拿到的文本生产方式】的加权平均——而权重是有人选的。 【显式】三条可查的事实: 1. Brown 语料库(1961)是 100 万词,500 篇 × 2000 词,15 个类别。每一类的配额是【设计】出来的,不是【抽】出来的。 2. Biber (1993, Literary and Linguistic…

「齐普夫律是语言的指纹,还是你分词器的指纹?」——一个零模型如何冒充定律

【锚点】这一篇只钉一个判断:在语料里测出幂律指数 α≈1,几乎不构成关于「语言」的证据——它更可能是在测你的【分词算子】、【语料规模】和【截断点】。 【显式】Zipf 1949:词频 × 排名 ≈ 常数,英语 α≈1。这条曲线被引用了七十多年,被当作「语言的经济性」的铁证。 【隐式】但 Miller 1957(Am. J. Psychol.…

「significant」的词源意思是「携带意义」——它如何被科学修辞漂白成「p<0.05」

【锚点】这一篇只钉一个判断:统计学里被滥用得最狠的不是 p 值,是「significant」这个词。它的【语义漂白】不是修辞小毛病,而是一台把「判断」偷换成「阈值」的语言机器。 【显式】拉丁语 significare = to signify,即「作为……的符号、携带意义」。19 世纪英语里 significant 的主义是「有意义的、值得注意的」。Fisher 1925《Statistical…

引用不是知识传递:它是一句把风险交给权威的语法

【锚点】这一篇只讲一个可迁移判断:【引用不是把知识从 A 搬到 B,而是把认识论风险从作者转移给被引权威】。 【显式】Garfield 1955 建 Science Citation Index 后,引用被量化为影响因子;今天引用数常被读成“影响力”。但引用在句法里常不是“我学到了”,而是“我依从/我采用/我跟随”。方法段里的 “we follow Smith (2020)”…

Google Ngram 上那条「文化演化曲线」,可能只是语料库自己的影子

【锚点】这一篇只钉一个判断:Google Books Ngram 上那些漂亮的「文化演化曲线」,多数时候不是文化在变,而是【语料库的构造成分】在变。语料库不是文化的镜子,是采集决策留下的化石。 【显式】Michel 等 2011 年在 Science 发《Quantitative Analysis of Culture Using Millions of Digitized…

「声望变体的最佳执行者不是它的受益者」:超正确、语言不安全感,与度量里的分母

【锚点】这一篇只钉一个判断:社会语言学里最稳的经验发现之一——对标准变体执行得最卖力的,不是地位最高的那群人,而是紧贴在他们下面的那群人。任何按「对规范的符合度」排序的度量,都会把中间层错认成顶层。 【显式】Labov 1966 年纽约百货公司调查。三家店按档次排:Saks(高档)、Macy's(中档)、Klein's(折扣)。变项是 fourth floor 里的 /r/——纽约口音里 r…

「词频不是词义」——为什么语料库语言学最大的谎言是『出现次数=重要性』

做语料库语言学的人都知道一个行业秘密:词频表是最容易骗人的东西,也是最难被质疑的东西。 经典案例:在英语学术语料库中,『however』的出现频率大约是『nevertheless』的3倍(COCA数据:however约每百万词400次,nevertheless约130次)。但如果你据此推断『however』更重要、更核心,你就犯了一个category…
