Abstract

The embodiment of the invention provides a text matching method based on a text similarity model. The method comprises the following steps of: receiving text information and determining a feature vector of the text information, wherein, the feature vector at least comprises a text string, a text phonetic alphabet and a word vector; Feature vectors are input into the text similarity model; Obtaining the feature similarity of the output of the text similarity model; At least one preset statement reach a preset feature threshold is determined as match text of that text information according to the feature similarity. The embodiment of the invention also provides a text matching system based on a text similarity model and a training method and system of the text similarity model. The embodiment of the invention determines the feature similarity between the user input statement and each preset statement in the text similarity model by using the text similarity model considering a pluralityof dimension feature vectors, and further determines the matching text with relatively high precision.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to a text matching method and system based on a text similarity model. Background technique [0002] Text similarity calculation is a basic problem in natural language processing, and text similarity algorithms are needed as support in many fields. In daily life, due to the user's colloquial description, the use of input methods, or hand errors, the user's description is not as standard as the formal text, but the user's description still contains the information that the user wants, accurate To capture these weak information, you need to use text similarity algorithm. For example, the user inputs "Where is the Yangtze River Bridge?" In fact, the user really wants to ask "Where is the Yangtze River Bridge". How to search for "Yangtze River Bridge" in the preset corpus according to "Where is the Yangtze River Bridge?" is an important application scenario of the text simil...
