Embodiment 1
[0048] This embodiment provides a query word error correction method in video search, please refer to figure 1 , the method includes:
[0049] Step S11: receiving the query word input by the user;
[0050] Step S12: Perform word deletion processing on the query words to obtain a word string set;
[0051] The rules for word deletion processing are set in advance. The word deletion processing can be to delete each word of the query word to obtain a string set, or to delete multiple words of the query word to obtain a word string set, or to delete each word of the query word to obtain a string set. Each word is deleted separately and multiple words are deleted respectively to obtain a string set.
[0052] For example, the query word (query) input by the user is "Legend of Heroes of Shooting Mink". Delete each word of the query word to obtain the string set as follows: delete the first word of the query word to get "The Legend of Diao Heroes"; delete the second word of the quer...
Embodiment 2
[0088] This embodiment provides a query word error correction device in video search, please refer to Figure 4 , the device consists of:
[0089] A receiving unit 11, configured to receive a query word input by a user;
[0090]The processing unit 12 is used to perform word-deletion processing on the query word to obtain a word string set;
[0091] The rules for word deletion processing are set in advance. The word deletion processing can be to delete each word of the query word to obtain a string set, or to delete multiple words of the query word to obtain a word string set, or to delete each word of the query word to obtain a string set. Each word is deleted separately and multiple words are deleted respectively to obtain a string set.
[0092] The matching unit 13 is used to use each word in the word string set and the query word to match the error correction candidate word dictionary obtained in advance to obtain the error correction candidate word;
[0093] The error c...
Embodiment 3
[0105] This embodiment provides another query word error correction device in video search, please refer to Figure 6 , the device is relatively Figure 4 Disclosed devices also include:
[0106] The dictionary generation unit 15 is used to receive the words input by the user, use the words as error correction candidates, perform word deletion processing on the words, obtain a set of word strings after word deletion, and establish the words and words , the corresponding relationship between the word string sets after the word deletion process.
