Abstract

The invention discloses a spelling error correction method and system of an ES search engine, and relates to the technical field of information. The method comprises the following steps of: dividing spelling content input by a user into a plurality of entries by adoption of an ansj word segmentation device; carrying out error detection on each entry, if an error entry exists, searching error models matched from the error entry from an error model library, and obtaining correction candidate words corresponding to the error entry from the matched error models; calculating a score, under each matched error model, of each correction candidate word according to the matched error models, and forming a score vector according to the score under each matched error model; processing the score vectors by adoption of an L2R model so as to generate scores of the error models, and determining a total score of each correction candidate word according to the scores of the error models and a language model; and determining the correction candidate word with the highest score in the total score as a correct candidate word, and displaying the correct candidate word. The method and system disclosed by the invention can improve the correctness of spelling error correction.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a spelling error correction method and system for an ES search engine. Background technique [0002] Elastic Search (ES for short) is a Lucene-based search server that provides a distributed multi-user capable full-text search engine developed in Java and released as open source under the Apache license. It is currently a popular enterprise level search engine. At present, spelling error correction in search engines, also called spell check, is a function widely used by various search engines, which can return correct query requests according to wrong query content input by users. [0003] The spelling error correction method in the prior art is usually: the number of times the user clicks and enters the search results of the query word after the error correction word is provided according to the user's search log statistics, the number of times the user clicks the error co...
