The invention provides an NER-based non-standard Chinese express sending information identification method and system. The method comprises the steps of: uniformly acquiring express sending information from order placing data of an express company, and preprocessing the data to obtain a labeling data set; reading the data, and establishing a text vectorization model for word feature representation to obtain word embedding and position embedding; establishing a time sequence probability prediction model for semantic decoding to obtain a corresponding tag score probability; establishing a label transition probability in a maximum probability prediction learning data set, and correcting the output of the time sequence probability prediction model to obtain an accurate and reasonable label prediction sequence; and carrying out visual display on a non-standard Chinese express sending information entity identification result. According to the NER-based non-standard Chinese express sending information identification method, the context information in the text is mined from the forward and backward directions, and the relevance between the characters is considered, so that a more accurate prediction sequence is output, and the condition that the element recognition precision of the mailing information is relatively low when the input of the user is not standard is well improved.
Description
Technical field [0001] The present invention relates to the field of intelligent express delivery, and more particularly to NER-based non-standard Chinese express delivery information identification methods and systems. Background technique [0002] With the rise of the Internet and e-commerce, the express delivery industry has developed rapidly. This has brought huge pressure to the end courier's quarters and factions. How to enhance the user experience and the shipping efficiency of the express delivery industry have become the current focus of the current research. By reducing the cumbersome to standardize user express mail information in the delivery of the courier, it is possible to improve the delivery efficiency of the courier, the delivery efficiency of the end courier. It is a feasible and effective way to solve the current express delivery and delivery efficiency. . [0003] In the prior art, only the user input specification, that is, each customer enters the text form...
