The invention discloses a text expectation consistency evaluation method and system based on an ID3 algorithm, and relates to the crossing field of text analysis and data mining, and the process of the method comprises the following four steps: 1, collecting multi-source text and expert experience data, and generating a structured feature data set through cleaning, OCR conversion, word segmentation and TF-IDF extraction; 2, constructing a general index library and a special index library, and dynamically adjusting weights; 3, training an ID3 decision tree by using the labeled historical text to realize matching of classification of the to-be-evaluated text and the reference text, and changing a C4.5 adaptive complex text; fourthly, scores and grades are calculated according to three indexes such as the text target coverage rate in a weighted mode, manual abnormal value correction is supported, and Top5 similar reference texts are recommended. The problems that in the prior art, index construction depends on manpower, evaluation is one-sided, and algorithm interpretation is weak are solved, and the method is suitable for scenes such as enterprise document auditing, academic paper checking and government affair text specification checking.

This application provides a method and related equipment for identifying water traffic events in port waters, belonging to the field of intelligent transportation technology. The method includes: acquiring first port data within a target port waterway; wherein the first port data includes vessel AIS data and port business data; preprocessing the first port data to obtain second port data; constructing preset semantic feature data based on the second port data; and identifying traffic events using a preset event recognition decision tree model based on the preset semantic feature data to obtain traffic event type data; wherein the preset event recognition decision tree is constructed based on the ID3 algorithm. This application can effectively improve the accuracy of identifying water traffic events in port waters and enhance the reliability and generalization ability of event recognition in complex water environments.
