Abstract

The invention provides a new energy policy information extraction method and system. The method is characterized by processing a new energy policy into a new energy policy text in a set format; basedon a pre-established new energy policy feature dictionary library, using a punctuation symbol automatic identification sentence division method to perform sentence division and marking on the new energy policy text, outputting a division and marking result, and generating a text sentence library; and based on a unified service interface, generating key information of a new energy policy feature dictionary library and a text statement library according to the text statement and outputting the key information.

Description

technical field [0001] The invention belongs to the fields of new energy policy evaluation and text mining, and specifically relates to a new energy policy information extraction method and system. Background technique [0002] Under the multiple challenges of environmental pollution, climate change and the depletion of fossil energy, new energy, mainly renewable energy, is playing an increasingly important role in the energy strategies of various countries. In order to promote the development of the renewable energy industry, my country promulgated the "Renewable Energy Law" in 2005, and established a renewable energy target and planning system, a fixed electricity price and mandatory grid connection system, and a cost sharing and subsidy system. As of May 2018, around the implementation of the "Renewable Energy Law", the central government and governments at all levels have issued a series of policies and related supporting documents, gradually forming a new energy and rene...
