DSpace at VNU: Extraction of Vietnamese collocation from text corpora

Extraction of Vietnamese collocation from text corpora Đỗ Thị Ngọc Quỳnh Trường Đại học Công nghệ Luận văn Thạc sĩ ngành: Khoa học máy tính; Mã số: 60 48 01 Người hướng dẫn: TS Lê Anh Cường Năm bảo

in each language is really necessary, to improve the accuracy and the nature of the application of natural language processing, as well as help to learn a new language easier However, in Vietnam, the study of collocation is quite a new field This paper focused on researching some method of extracting collocations methods to find efficient model for the Vietnamese collocations extraction The mentioned methods were based on some classic statistical methods commonly used such as frequency, t-test, chi-square, mutual information We also suggested some general method using linguistic measure to increase the accuracy of the process of extraction Input data included the data has been through a POStagging and data has been parsed By running the program with different methods and combination of multiple methods together, comparing the accuracy of the method, we draw out the efficient method of extracting of Vietnamese Collocation from Text Corpora Keywords Xử lý ngôn ngữ; Xử lý liệu; Ngơn
