概要	Keyword-in-context (KWIC) analysis is the indexing and display technique that presents every occurrence of a chosen keyword aligned in a fixed central column, flanked by a set span of the words that precede and follow it. Invented by H. P. Luhn in 1960 to index technical literature, the KWIC format became the standard way to read a concordance: by stacking instances of the keyword so they line up vertically, it lets an analyst scan the surrounding co-text for recurrent neighbors and patterns. It is the specific display layer underlying broader corpus concordance work, valued because alignment turns a list of scattered occurrences into a visually legible pattern. Today KWIC views are the default output of every corpus-analysis tool and the entry point for studying collocation, colligation, and meaning in context.	Corpus concordance analysis is a core corpus-linguistic technique that retrieves every occurrence of a search word or phrase from a large body of machine-readable text and displays them in keyword-in-context (KWIC) format — the target term aligned in a central column with its surrounding co-text. By reading and sorting these lines, analysts uncover the recurrent patterns, collocations, and meanings of words as they are actually used, grounding linguistic claims in attested evidence rather than introspection.
