摘要

Disclosed is a device for generating an aligned corpus based on unsupervised-learning alignment, and a method thereof, a device for analyzing a destructive expression morpheme using an aligned corpus, and a method for analyzing a morpheme thereof.;The morpheme analyzing device includes a knowledge database and an analyzer. The knowledge database includes an aligned corpus for storing a plurality of knowledge information sets used for a per-language morpheme analysis, and stores a morpheme dictionary for storing morpheme information corresponding to a normal expression and normal expression information corresponding to a destructive expression (here, the destructive expression represents an expression that is erroneous in orthography or is not normalized and standardized). The analyzer performs a morpheme analysis on an input separate word by use of the knowledge database and outputs an analysis result, and when a morpheme on the input separate word is not provided in the morpheme dictionary, finds a normal expression corresponding to the destructive expression by use of the aligned corpus regarding the destructive expression included in the input separate word, and performs a morpheme analysis.
