Dish name identification method and device

Abstract

The invention discloses a dish name identification method and device. The dish name identification method comprises the following steps: acquiring a to-be-identified original dish name; determining acontext related word vector of at least one word included in the original dish name through a language model, wherein the language model is at least learned from a first original dish name set withoutdish name information; and identifying a dish name corresponding to the original dish name according to the context related word vector through a dish name identification model, wherein the dish nameidentification model is learned from a second original dish name set marked with dish name information. By adopting the processing mode, dish names of a large number of original dish names can be well identified through the dish name identification model learned from a small number of manual annotation data sets, and the situation that dish name annotation is conducted on the original dish namesthrough a large amount of manpower and time is avoided; therefore, two aspects of relatively low manual annotation cost and relatively high dish name identification accuracy can be effectively considered.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to a dish name recognition method and device. Background technique [0002] In the local life service O2O business scenario, on the one hand, merchants are allowed to freely edit the names of dishes to attract customers, such as "Beijing Sauce Shredded Pork Package", "Beijing Sauce Shredded Pork Rice Bowl" and other dish names; The name recognition technology automatically normalizes (standardizes) the names of a large number of dishes. For example, the real dish corresponding to "Beijing Sauce Shredded Pork Package" is "Beijing Sauce Shredded Pork", and the real dish corresponding to "Beijing Sauce Shredded Pork Rice Bowl" It is "Beijing sauce shredded pork rice bowl" itself, in order to facilitate data processing such as search and recommendation on standardized dish names. [0003] A typical dish name recognition method is as follows. Through the m...
