Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a text error correction method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0027] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. figure 1 It shows a hardware structure block diagram of a computer terminal (or mobile device) for implementing the text error correction method. Such as figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more (shown by 102a, 102b, ..., 102n in the figure) processor 102 (the processor 102 may include but not...

Embodiment 2

[0116] According to an embodiment of the present invention, a text error correction device is also provided, such as Figure 5 As shown, the device includes: an acquisition module 502 , an evaluation module 504 , a determination module 506 and an error correction module 508 .

[0117] Among them, the acquisition module 502 is used to obtain the candidate words corresponding to the target text, wherein the candidate words are obtained by deforming the words contained in the target text; the evaluation module 504 is used to evaluate each candidate word by using multiple evaluation methods , to obtain the evaluation value of each candidate word under multiple evaluation methods; the determination module 506 is used to obtain at least one candidate word for error correction according to the evaluation value corresponding to each candidate word; the error correction module 508 is used to Error correction is performed on the target text based on the at least one candidate word for e...

Embodiment 3

[0134] According to an embodiment of the present application, a text error correction system is also provided, and the system includes:

[0135] processor; and

[0136] The memory, connected to the processor, is used to provide the processor with instructions for processing the following processing steps: obtain candidate words corresponding to the target text, wherein the candidate words are obtained by deforming the words contained in the target text; Evaluate each candidate word to obtain the evaluation value of each candidate word in multiple evaluation methods; obtain at least one candidate word for error correction according to the evaluation value corresponding to each candidate word; At least one candidate word corrects the target text.

[0137] Based on the scheme provided by the above-mentioned embodiments of the present application, the candidate words corresponding to the target text are first obtained, wherein the candidate words are obtained by deforming the wor...

Abstract

The invention discloses a text error correction method, device and system. The method comprises the steps that candidate words corresponding to a target text are acquired, and the candidate words areobtained by deforming words contained in the target text; evaluating each candidate word by adopting multiple evaluation modes to obtain an evaluation value of each candidate word under the multiple evaluation modes; obtaining at least one candidate word for error correction according to the evaluation value corresponding to each candidate word; and performing error correction on the target text based on the at least one candidate word used for performing error correction, thereby achieving the purpose of text error correction. According to the text error correction method and device, the candidate words are recalled through multiple means, the candidate words are scored through multiple evaluation modes, at least one candidate word used for error correction is obtained through searching and sorting, and then the technical problems that text error correction is low in accuracy and high in error correction cost are solved.

Description

technical field [0001] The present invention relates to the field of language information processing, in particular to a text error correction method, device and system. Background technique [0002] With the development of search technology, various input methods emerge in an endless stream. However, when users input text, they do not necessarily check and modify their own input. There are often spelling mistakes in the input words. During the dialogue between people, the wrong words can be interpreted by people in combination with the context. Meaning, which is equivalent to implicitly "correcting" the text. For computer systems such as similarity calculation and search inversion, such non-standard input greatly increases the sparsity of the input and has an adverse impact on system performance. So a spelling error correction method and system with good performance are very valuable. [0003] According to the situation that the user cannot get the search results from th...
