Problems solved by technology

However, for error types 4 and 5, effective and accurate error correction cannot be performed, and the error correction accuracy is low
[0009] It can be seen that the existing vertical search engine query information error correction scheme cannot be applied to all error types, even if it is barely capable of error correction, the accuracy of error correction is low

Embodiment 1

[0035] refer to figure 1 , shows a flow chart of steps of a method for correcting query information of a vertical search engine according to Embodiment 1 of the present invention.

[0036] The query information error correction method of the vertical search engine of the embodiment of the present invention may include the following steps:

[0037] Step S102: Segment the query information input by the user into words.

[0038] For example: the query information entered by the user is "the latest issue of the fast east base camp", and the subsequent query information is "fast / east / base camp / latest / first issue".

[0039] Step S104: After initializing the cursor, move the cursor in units of word segmentation according to the set rules to obtain subquery information.

[0040] Wherein, the query information includes multiple sub-query information, and each sub-query information includes at least one participle.

[0041] The number of cursors can be two. The two moving cursors are...

Embodiment 2

[0052] refer to figure 2 , shows a flow chart of the steps of a query information error correction method for a vertical search engine according to Embodiment 2 of the present invention.

[0053] The query information error correction method of the vertical search engine of the embodiment of the present invention may include the following steps:

[0054] Step S202: The search engine generates an error correction dictionary.

[0055] A preferred way of generating an error correction dictionary is as follows:

[0056] S1: Receive an initial alias table for input.

[0057] The initial typographical list is composed of common typographical pairs artificially sorted out according to the structure and shape of Chinese characters and writing habits. The typographical list mainly includes typographical typos, such as: (爱, 爽), (子, 孙), (沉,酒) ), (Mother, Wu), (Yu, She), (Mother, Wu), (Day, Yue), (Mei, Jiu), (Le, East) and so on. The search engine receives an initial alias table ente...

Embodiment 3

[0098] refer to image 3 , shows a flow chart of steps of a method for correcting query information of a vertical search engine according to Embodiment 3 of the present invention.

[0099] The query information error correction method of the vertical search engine in the embodiment of the present invention mainly includes two parts, the first part is the creation and update maintenance of the error correction dictionary, word segmentation protection table, error correction blacklist, and the second part is the search engine through the error correction dictionary , word segmentation protection table, and error correction blacklist for the specific process of error correction. Below, refer to image 3 The contents of these two parts are explained separately.

[0100] The creation, update and maintenance of the error correction dictionary includes the following steps:

[0101] Step 1: Create an initial alias table.

[0102] According to the structure and shape of Chinese cha...

Abstract

The invention provides an error correction method and system for query information of a vertical search engine. The method comprises the steps of performing word segmentation on query information input by a user; initializing a cursor and moving the cursor by taking a segmented word as a unit according to a set rule to obtain query information; obtaining error correction information corresponding to sub query information from an error correction dictionary; adopting the error correction information to replace the sub query information in the query information to obtain query information subjected to error correction; judging whether operation of traversing the query information by moving the cursor is ended or not; if not, returning to perform the step of obtaining the sub query information by moving the cursor according to the set rule; or if yes, taking the query information subjected to the error correction as an error correction result of the query information input by the user. The error correction method for the query information of the vertical search engine, provided by the invention, can be suitable for error correction of any error type; and the error correction is performed based on the error correction dictionary, so that the accuracy of error correction is high.

Description

technical field [0001] The invention relates to the technical field of search engines, in particular to a query information error correction method and system for a vertical search engine. Background technique [0002] With the rapid development of the Internet in modern society, search engines have become one of the main ways for people to obtain information from the Internet with massive data, and the way users interact with search engines comes from the queries entered by users. The correctness of query content is to improve search results. critical factor in the accuracy of the results. Therefore, the query error correction of search engines is of great significance for improving the accuracy of query results and improving user experience. [0003] For vertical search engines (such as video search engines), the common types of Chinese query errors mainly include: 1. Homophony typos (such as: "Rooting Tomb Notes" written as "Rooting Tomb Notes"); 2. Fuzzy pinyin errors (...
