Abstract: PURPOSE: A method for automatically indexing sentences is provided to increase the efficiency of extracting index terms by automatically indexing Korean and English sentences standardized using a PDA(Push Down Automata). CONSTITUTION: Sentences in a document are recognized(201). Disused words are registered in a disused word database(203). The disused words registered in the disused word database are extracted. After that, arbitrary characters are substituted for the words(202). The sentences substituted are read in the unit. In case that an error is generated, an error message is transmitted. Index terms are extracted from the sentences using a PDA indexing engine(205). In case that the processing of a sentence is completed, a next sentence in the document is recognized(204). The structure of the stack of the PDA is divided into a state, an index and a symbol stack.
