The invention provides an error correction method and device for search terms, wherein the method comprises the steps of recognizing wrong search terms; calculating weighted edit distance between the search terms and hot terms obtained in advance using weighted edit distance algorithm, wherein during the weighted edit distance calculating process, with respect to operations to transform the search terms into hot terms, respectively operation of inserting characters, operation of deleting characters, operation of replacing characters with similar form or pronunciation, operation of replacing characters without similar form or pronunciation and operation of switching characters, weightings of different numerical value are set; selecting hot terms of preset numbers to conduct error correction prompt according to the weighted edit distance and hotness of the hot terms. According to the error correction method for search terms , error correction accuracy rate for the wrong search terms can be reduced.

The invention discloses a Chinese error correction method based on mutual information. The method comprises the following steps: obtaining a target short sentence to be corrected, performing word segmentation processing on the target short sentence, obtaining a word segmentation sequence, and determining a pinyin combination sequence corresponding to the word segmentation sequence , each pinyin combination in the pinyin combination sequence corresponds to each participle in the word segmentation sequence one by one, and based on the homophone words mapped by each pinyin combination in the pinyin combination sequence, the error correction word sequence set is obtained, and the error correction word sequence set is calculated. The mutual information of each error correction word sequence, according to the size of the mutual information, determines the error correction result of the target short sentence. By applying the technical solution provided by the embodiment of the present invention, the error correction of the target short sentence can be performed according to the frequency of words and the frequency of word collocation, and the accuracy rate of Chinese error correction can be improved. The invention also discloses a mutual information-based Chinese error correction device, a mutual information-based Chinese error correction device and a computer-readable storage medium with corresponding technical effects.

The invention relates to a correction system and method mainly used for a large-span gantry crane and particularly relates to an automatic correction system and method for traveling of a gantry crane. The automatic correction system comprises an encoder group, a programmable controller, a traveling motor for driving traveling mechanisms of rigid legs and flexible legs of the gantry crane and a frequency converter for controlling the traveling motor, wherein the encoder group is connected with the programmable controller, and the frequency converter is connected with the traveling motor. Therefore, the automatic correction system has the advantages that (1) the automation degree is high, and automatic correction can be realized without need of artificial intervention; (2) the error correction accuracy is high, the deviation degree can be accurately detected by utilizing the encoder group, the traveling motor is driven by the frequency converter to carry out accurate adjustment, simultaneously, the slipping phenomenon of the low-speed ends of traveling wheel groups can be found in time, and corresponding adjustment can be made; and (3) the application scope is wide, the deformation of a traveling track of a cart and the whole deflection of the cart can be judged and error operation can be prevented.

The invention discloses a data error correction method and a device on a flash storage medium and relates to the field of data storage. The data error correction method and the device on the flash storage medium are used for improving error correcting accuracy of data on the flash storage medium. Metadata which correspond to user data are written into a physical main sector and a physical backup sector. When the user data is read, the metadata in the physical main sector and the physical backup sector can conduct automatic error correction processing, and the metadata obtained by the automatic error correction processing conduct error correction to the user data. The data error correction method and the device on the flash storage medium can improve error correction accuracy of the data on the flash storage medium.

Embodiments of the present application provide a text information processing method, device, storage medium, and electronic equipment. The method includes: performing word segmentation processing on the text recognition result to be corrected to obtain multiple text entries; identifying the text to be corrected Inputting the results into a search engine to obtain at least one search result; matching each text entry in the plurality of text entries with the search result to obtain a matching result of the text entry in the search result; splicing matching results corresponding to each text entry in the plurality of text entries to obtain a splicing result of each of the at least one search result, and a collection of each of the splicing results forms a candidate result set; The text recognition result to be corrected is matched with each splicing result in the candidate result set to determine the corrected text recognition result. In order to improve the accuracy of error correction of text recognition results.
