A text data retrieval method and device

Abstract

The present application discloses a text data retrieval method and device. The method includes: firstly, constructing feature vectors extracted from preset text data into a vector set, and the feature vectors include first keywords and first feature weights; then, Classify the set of vectors according to the first similarity between the preset hotspot vectors and the feature vectors to obtain the feature vector category library; secondly, construct the search vector according to the preset search hotspots, and the search vector includes the second keyword and the second feature weight ; Then, randomly select a category in the feature vector category library, calculate the second similarity between each feature vector in the category and the retrieval vector, and obtain the maximum similarity; finally, use the first feature weight instead of the second one according to the preset conditions Two feature weights, and iterative retrieval, get the retrieval feature vector. It solves the technical problem that the retrieval effect is poor and the actual application requirements cannot be efficiently met.

Description

technical field [0001] The present application relates to the technical field of text retrieval, in particular to a text data retrieval method and device. Background technique [0002] In recent years, the rapid development of the Internet has ushered in an era of explosive growth of information. With the gradual transfer of daily life to the Internet, the era of big data has become inevitable. As a frontier concept of the global Internet, big data mainly includes two characteristics: one is the sharp increase in the amount of information; the other is the exponential growth in the amount of information available to individuals. [0003] Artificial intelligence is the study of how computers simulate or implement human learning behaviors to acquire new knowledge or skills, and reorganize existing knowledge structures to continuously improve their own performance. With the development of artificial intelligence, artificial intelligence has also been applied to various fields...
