Meaning

Analysis; analytical study; parsing. Breaking down complex data, structures, or phenomena into component parts to understand them.

A central term in mathematics (mathematical analysis — 解析学), computer science (parsing — 構文解析), and natural science. In mathematics, 解析 specifically refers to the branch of calculus and complex analysis. In computing, 構文解析 (syntactic parsing) and 字句解析 (lexical analysis) are key compiler design concepts. The compound appears in 解析的 (analytical) and 解析解 (analytical solution), contrasted with 数値解 (numerical solution). Distinguished from 分析 (bunseki), which is more common in social science contexts.

Examples

1. このデータセットを統計的に解析することで、潜在的なパターンが浮かび上がるだろう。 By statistically analysing this dataset, latent patterns will likely emerge.
2. 流体力学の問題では、解析的な解が得られない場合に数値計算が用いられる。 In fluid dynamics problems, numerical computation is used when an analytical solution cannot be obtained.
3. コンパイラは、ソースコードを構文解析して中間表現に変換する。 A compiler parses source code and converts it into an intermediate representation.
