DEVICE AND METHOD FOR ANALYZING SIMPLE SENTENCE STRUCTURE OF EVENT SENTENCE FOR EXTRACTING INFORMATION |
摘要 |
PURPOSE: A device and a method for analyzing a simple sentence structure of an event sentence for extracting information are provided to improve a performance of an information extracting system by dividing the long and complex event sentence into a simple sentence based on a declinable word, and extracting the information after analyzing the structure of the divided sentence. CONSTITUTION: A simple sentence range recognizer(10) recognizes a range of the simple sentence from the inputted complex event sentence by using the sentence form information and considering a modifier clause. A necessary component generator(20) generates a necessary component from the recognized simple sentence by using the lower category information and the object name co-occurrence information. A necessary component extender(30) obtains the finally analyzed structure of the simple sentence by recognizing/extending the generated necessary component through a complex noun dictionary and the object name information.
