MI-score and T-score

Some important differences between MI-score and t-score are:
(1). MI-score is a measure o strength of collocation; t-score is a measure of certainty of collocation.
(2). The value of an MI-score is not particularly dependent on the size of the corpus. For the t-score, however, corpus size is important, because the amount of evidence is being taken into account.
(3). MI-score can be compared across corpora, even if the corpora are of different sizes, but absolute t-scores cannot be compared across corpora (though it is reasonable to compare t-score rankings) because the size of the corpus will affect the t-score.

请问各位:
有没有现成的可以计算MI-score的软件啊,而且我是要计算CLEC中的数据!

WST4.0和Collocate1.0以及免费的AntConc3.2等都可以计算MI值的。

Of course Xaira can also do that. But I think what Majorlv511 wanted is a more tailorable calculator like this one - Significance tests calculator:

which allows you to compute z, t and MI scores.

请教这个TZMI-score calculator 计算器中的数据,分别该填什么啊?
我现在要做一个CLEC里面的统计,我的keyword是"want", collocate是"to"
关于corpus details 部分,
tokens in corpus 是1070602 (本来是1207879,后来剔除了汉语拼音的专有名词和失误标注)
但这里的 overall occur是指什么呀?

还有后面的span是8
concordance lines是不是就指我所检索出的所有包括want的行数?
这里的observed 又该是什么呢?

谢谢了!

我这里不知道怎么贴图上来 :-(

我也不知道什么是overall occur 还有concordance lines 和observed 各指的是什么。

想请教前辈,用Antconc 3.2.1如何算MI值呀?还望赐教!!!
非常感谢!!!谢谢啦!!!

在AntConc 的 Tool Preferences 里选 Collocates, 然后选中右面的 Collocation measure, 在其下的 Other Options 选项中可以选 MI 或者 T-Score, 确定。
这样在检索一个词的搭配词的时候, 会有一栏名为 Stat, 应该就是它了。

我也想知道Antconc怎么计算MI/T值,麻烦前辈们讲解!
谢谢!

很多语料库语言学教程里都有关于MI值和T值的计算方法 公式略有一点不同 但都差不多
