Embodiment Construction
[0039] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0040] Embodiment 1 of the present invention provides an information extraction method for the ITU Radio Regulations. The method mainly includes two steps for information extraction of Articles of the Radio Regulations: text preprocessing and article understanding. In addition, a professional corpus based on the field of frequency declaration has been constructed;
[0041] Step 1) Text Preprocessing
[0042] Since the electronic version of ITU's official "Radio Regulations" is provided in the form of pdf and docx files, and there are thousands of clauses, some clauses are further subdivided, which makes it extremely inconvenient for satellite reporting operators to consult and analyze. In addition, the pdf and docx file formats are not conducive to computer understanding and processing. Therefore, it is necessary to preprocess the text of th...
