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 ,)
