潜在语义分析 Latent Semantic Analysis
Latent Semantic Analysis (LSA; Landauer et al., 2007) provides measures of semantic overlap between sentences or between paragraphs. Coh-Metrix 3.0 provides eight LSA indices. Each of these measures varies from 0 (low cohesion) to 1 (high cohesion).
潜在语义分析（LSA；Landauer 等，2007 ）提供了句子之间或段落之间语义重叠的测量方法。Coh-Metrix 3.0 提供了八种 LSA 指数。每个指数都从 0（低衔接）到 1（高衔接）不等。
