Embodiment 2

[0113] Embodiment 2 On the basis of Embodiment 1, the judgment result of S205 is verified to further improve the accuracy of judging the correctness of the input character string.

[0114] When the pinyin in the log library appears in the input string but the corresponding query word does not appear, the input is wrong in most cases, but a small part is correct. Therefore, it is necessary to verify the first preliminary judgment that the input character string is wrong data in Embodiment 1, so as to avoid misjudgment.

[0115] see image 3 , is the flow chart of Embodiment 2. S301 is executed on the basis of S201-S205: when it is determined that the input character string has an error, verify the judgment result, specifically: replace the corresponding position of the input character string with the query words in the set Chinese characters, and compare the word segmentation between the original input string and the replaced string to verify whether the judgment result of the...

Abstract

The invention discloses a method and a device for confirming correctness of character strings input in a search engine, wherein, the method comprises the following steps: the input character strings input by the user in the search engine are obtained; the input character strings are utilized and Pinyin strings of the input character strings are inquired in the preset set to inquire, and the set comprises inquiry words with the one-to-one corresponding relation and Pinyin strings of the inquiry words; the correctness of character strings input is judged; if the Pinyin strings in the set are matched with the Pinyin strings of the character strings input or substrings of the Pinyin strings, and the inquiry words in the set corresponding to the Pinyin strings matched in the set are not included in the character strings input, the device can confirm that errors exist in the input character strings; otherwise, the device can confirm that the character strings input are correct. By adopting the method and the device, the invention can solve the problem of inaccuracy and misjudgement of the prior scheme.

Description

technical field [0001] The invention relates to the technical field of network search engines, in particular to a method and a device for determining the correctness of an input character string in a search engine. Background technique [0002] According to statistics, 8% of the input strings entered by users in search engines contain errors. For example, "library" is input as "library management". User "Did you mean: library". When QC is running, the first step is to judge whether the input string contains errors. If the input is correct, no error correction will be performed; otherwise, the error correction step will be performed. [0003] Search engine users mainly use the pinyin input method to type in the input string, so the wrong input is mainly a homonym error, so currently QC generally judges the correctness of the input string based on the homonym. For example, if the user enters "library management", the existing QC will retrieve all query words that are pronoun...
