Problems solved by technology
[0003] The existing address processing steps mainly include text preprocessing, feature extraction, and specific downstream business models. Most of the text preprocessing methods are different, resulting in inconsistent data usage. Different processing logic may be designed for different data, and Will cause waste of data usage
In addition, the existing address feature representation is strongly dependent on the preprocessing rules, which is easy to cause error accumulation, and the representation vector is extremely sparse, which is not conducive to the calculation when applied to subsequent models

The invention provides a logistics address feature extraction method, system and device and a storage medium. The method comprises the steps of connecting information, corresponding to all attributes,of a logistics address in series to obtain a text character string; mapping the text character string into an ID sequence based on a text mapping dictionary, wherein the text mapping dictionary comprises preset mapping relationships between various attribute values of each attribute and IDs; mapping the ID sequence into a vector sequence by adopting an embedded layer; and inputting the vector sequence into an interactive feature extraction model, and extracting address features from output data of the interactive feature extraction model. The invention provides a unified text representation method based on pre-training, and the method comprises the steps of firstly mapping a text to an ID sequence based on a pre-processed text mapping dictionary, then mapping the ID sequence to a vector sequence through an embedded layer, carrying out the feature extraction in the vector sequence, and obtaining a logistics address feature in a unified form through extraction; therefore, unified representation after address feature extraction is realized.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a logistics address feature extraction method, system, equipment and storage medium. Background technique [0002] In logistics business scenarios, addresses are used everywhere, including address transfer to longitude and latitude, intelligent order distribution, and recommendation of collection points. Since each business scenario is relatively independent of each other, there are often differences in the processing and use of the address text. [0003] The existing address processing steps mainly include text preprocessing, feature extraction, and specific downstream business models. Most of the text preprocessing methods are different, resulting in inconsistent data usage. Different processing logics may be designed for different data, and It will cause waste of data usage. In addition, the existing address feature representation is strongly dependent on the preproc...
