Abstract

The invention discloses an information extraction method and system for an international electric connection radio rule, and the method comprises the steps: carrying out the preprocessing of a text of the international electric connection radio rule, and building a database for recording all terms; identifying all terms which may have a relationship from a database; for each clause possibly having the relationship, analyzing a specific relationship type between the clause possibly having the relationship and the clause having the association relationship; and by using a natural language processing method based on rule matching, extracting the number of the clause which has an association relationship with the clause which possibly has the relationship, and writing the number of the clause which has the association relationship and the specific relationship type into a corresponding position in a database. According to the method, named entity and entity relationship extraction is carried out on an international electric connection radio rule by adopting an NLP technology based on knowledge engineering; and the mutual relation among the terms is automatically combed, and a satellite network operator is supported to quickly track and master the radio rules.

Description

technical field

[0001] The invention relates to the field of satellite network frequency and orbit position resource protection, in particular to an information extraction method and system for ITU radio regulations. Background technique

[0002] The current satellite network data declaration is based on the Radio Regulations of the International Telecommunication Union (ITU). Operators need to be familiar with the provisions of the "Radio Regulations", but the "Radio Regulations" has many clauses, the full text is nearly 200,000 words, including thousands of various clauses, and will be revised and updated every time. It takes a lot of energy to understand and master the terms again.

[0003] In addition, the relationship between the clauses is intricate and complicated, and there are relationships such as "restrictive premise", "interdependence", "mutual exclusion", etc., which leads to relevant domestic satellite network declaration operators spending a lot of energy on ...
