Benefits of technology

This invention divides documents into smaller parts called fragments by setting certain rules before extracting specific words (called candidates) from them. These suggestions help reduce computational complexity while still capturing relevant content accurately. By doing this, it saves time and resources compared to traditional methods like keyword-based search engines.

Problems solved by technology

The technical problem addressed by this patented method for efficiently extracting important information from complex networks involves overcoming challenges associated with traditional methods such as Deep Learning models that require long processing times or manual intervention during analysis.

Abstract

The invention discloses an information extraction method and device and electronic equipment, and relates to the technical field of natural language processing. The method comprises the following steps of: segmenting a document to form a plurality of sentences; screening the plurality of sentences according to the target word rule set to generate a candidate sentence set, the candidate sentence set including a plurality of candidate sentences; obtaining text features of each candidate sentence; generating a probability that each candidate sentence is target information according to the text feature of each candidate sentence; and extracting candidate sentences of which the probabilities are greater than or equal to a preset probability threshold from the candidate sentence set to form a target information set. Therefore, through the information extraction method, preliminary screening is performed through the target word rule set, and the data processing amount of information extraction is reduced, so that the information extraction duration is shortened, and the information extraction accuracy is improved.
