Embodiment 1

[0032] Such as figure 1 As shown, it is the error correction method provided by Embodiment 1 of the present invention, which is used to correct the incorrect keywords entered by the user when searching, that is, to correct the keywords entered by the user when searching for which the search results cannot be obtained. Error correction, the method includes:

[0033] Step 101 , perform word segmentation processing on the keyword input by the user, and obtain the word segmentation of the keyword.

[0034] No matter in the field of search technology or other technical fields, it is first necessary to perform word segmentation processing on keywords input by users. The keyword entered by the user is usually a long character string, so it is necessary to segment the keyword entered by the user before performing subsequent query operations. If the keyword input by the user is "Beijing University of Posts and Telecommunications", the keyword is segmented to obtain three word segment...

Embodiment 2

[0080] Based on the aforementioned error correction method, Embodiment 2 of the present invention provides an error correction device, the structure of which is as follows Figure 4 shown, including:

[0081] A word segmentation unit 41, configured to perform word segmentation processing on the keywords input by the user, to obtain the word segmentation of the keywords;

[0082] Segmentation validity checking unit 42, used to check the validity of each segmentation, use the segmentation that has not passed the validity check as an invalid segmentation, and start the segmentation error correction unit;

[0083] Segmentation error correction unit 43, for correcting the invalid participle according to the outer code of the invalid participle, to obtain the participle after error correction;

[0084] The keyword error correction unit 44 is configured to replace the corresponding invalid participle in the keyword with the corrected participle to obtain the corrected keyword.

Abstract

The invention discloses an error correction method and a device thereof. The error correction method comprises the steps of performing word segmentation on keywords input by a user, so as to obtain the participles of keywords; performing the word segmentation on the keywords input by the user, detecting the effectiveness of each participle by the participles of the obtained keywords, and taking the participles which can not pass the effectiveness detection as invalid participles; correcting the invalid participles according to the outer codes of the invalid participles, so as to obtain the corrected participles; and using the corrected participles to replace the corresponding invalid participles in the keywords, so as to obtain the corrected keywords. According to the technical scheme, the participles can be corrected through the outer codes, the reasons for causing the input errors of the participles can be dramatically determined, the accuracy of correcting the participles can be improved, and the accuracy for correcting the keywords can be improved.

Description

technical field [0001] The invention relates to the field of search technology, in particular to an error correction method and device for correcting incorrect keywords input by a user when searching. Background technique [0002] With the development of search technology, for the situation that the search results cannot be obtained according to the keyword input by the user, the prior art provides several methods for error correction of the keyword input by the user: [0003] Method 1. Convert the keyword into pinyin, search the word segmentation corresponding to the pinyin from the database, and recommend the word segmentation with higher query frequency among the searched word segmentation to the user, so that the user can confirm the real keyword to be queried; And according to the keyword confirmed by the user to carry out the corresponding search. [0004] Method 2. Match the keyword entered by the user with the query word in the query word lexicon. If it is completel...
