Provided are a method and an apparatus for generating a keyword. The method for generating a keyword in a target document includes: extracting primitive single words from the target document; generating a candidate keyword by a combination of the primitive single words; calculating cohesion score between a first word and a second word included in the candidate keyword; calculating a context score of the first word and the second word based on similarity between two contexts by determining a periphery of a word where the first word and the second word simultaneously occur in a neighboring document as one context and determining the target document as a remaining one context; and selecting a final keyword based on the cohesion score between the first word and the second word and the context score of the first word and the second word.
