Pearson-correlation
在统计学中,皮尔逊积矩相关系数(英语:Pearson product-moment correlation coefficient,又称作 PPMCC或PCCs[1], 文章中常用r或Pearson s r表示)用于度量两个变量X和Y之间的相关(线性相关),其值介于-1与1之间。在自然科学领域中,该系数广泛用于度量两个变量之间的相关程度。它是由卡尔·皮尔逊从弗朗西斯·高尔顿在19世纪80年代提出的一个相似却又稍有不同的想法演变而来的。这个相关系数也称作“皮尔森相关系数r”。(In statistics, Pearson product-moment correlation coefficient (English: Pearson product-moment correlation coefficient, also known PPMCC or PCCs [1], the article used or Pearson s r r representation) is a measure of the two variables X and Y between correlation (linear correlation), a value between-1 and 1. In the natural sciences, the coefficient is widely used to measure the degree of correlation between the two variables. It is made a similar Karl Pearson Francis Galton in the 1880s but made a slightly different idea evolved. The correlation coefficient is also called Pearson s correlation coefficient r .)

说明: LSA的第一步是要去创建词到标题(文档)的矩阵。在这个矩阵里,每一个索引词占据了一行,每一个标题占据一列。每一个单元(cell)包含了这个词出现在那个标题中的次数。例如,词”book”出现在T3中一次,出现在T4中一次,而”investing”在所有标题中都出现了一次。一般来说,在LSA中的矩阵会非常大而且会非常稀疏(大部分的单元都是0)。这是因为每个标题或者文档一般只包含所有词汇的一小部分。更复杂的LSA算法会利用这种稀疏性去改善空间和时间复杂度。(The Little Book of Common SenseInvesting: The Only Way to Guarantee Your Fair Share of StockMarket Returns ,)
