[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0043] The components of the embodiments of the present application generally described and shown in the drawings herein may be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0044] Hereinafter, the terms "including", "having" and their cognates, which may be used in various embodiments of the present application, are intended only to indicate specific features, numbers, steps, operations, elements, components, or combinations of the foregoing items, and should not be understood as first excluding the existence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing items or adding the possibility of one or more features, numbers, steps, operations, elements, components, or combinations of the foregoing items.

[0045] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0046] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as those generally understood by those skilled in the art to which the various embodiments of the present application belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present application.

[0047] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] Usually, a large number of repeated words and sentences are marked in the marking process of key words and sentences, which makes the marking process occupy a large amount of memory and consume a large amount of CPU, thereby reducing efficiency.

[0049] Further analysis of the reasons shows that we usually extract key words and sentences from the chat text first, and then mark all the key words and sentences. However, due to the inclusion relationship between sentences and words in the chat text, the relationship between words in each sentence is complicated (including inclusion relationship and intersection relationship, etc.), and it is not possible to use a simple expression to extract each important word and sentence without duplication and separately.

[0050] Therefore, in order to solve the above problems, the present application proposes a keyword tagging method.

[0051] Please refer to Figure 1 , is a flowchart of a keyword tagging method proposed in an embodiment of the present application. Exemplarily, the keyword tagging method is applied to a tagging tool, for example, the tagging tool can be applied to a computer device such as a mobile phone, a host, or a tablet.

[0052] In some embodiments, Figure 1 As shown, the keyword tagging method includes:

[0053] S110, obtaining an original text, and numbering the characters of the original text.

[0054] The original text may be formed by a chat record between a client and a user, or may be formed by a text document converted from a voice call between a client and a user, or may be formed by other means, which are not limited here. The original text may be understood as the initial text that needs to be marked with keywords, and the text includes various characters, such as Chinese characters, English letters, Arabic numerals, punctuation marks, etc.

[0055] The text in the numbering of the original text can be understood as one or more of Chinese characters, English letters, Arabic numerals and punctuation marks, which can be freely selected according to actual conditions.

[0056] In the keyword tagging method of some embodiments, the characters of the original text are numbered, including:

[0057] Starting from the first character of the original text, each character is numbered in ascending order until the last character of the original text to obtain the digital number corresponding to each character.

[0058] For example, if Chinese characters, Arabic numerals and punctuation marks are all numbered, if the first sentence in the current original text is "The bank now gives you a quota for adjustment, which is equivalent to a 1 percentage point interest rate cut", then the corresponding numbers will be 0~20, "silver" will be numbered 0, and "1 percentage point" will be numbered 18, 19, and 20 respectively.

[0059] S210, extracting all keywords from the original text and obtaining a location identifier corresponding to each keyword.

[0060] The positioning identifier is composed based on the numbers of the characters in the keyword, and the positioning identifier includes the number corresponding to each character in the corresponding keyword.

[0061] For example, if Chinese characters, Arabic numerals, and punctuation marks are all numbered, if the current original text contains "The bank now gives you a quota for credit adjustment, which is equivalent to a 1-point interest rate cut", and the keywords are "quota adjustment" and "The bank gives you a quota for credit adjustment, which is equivalent to a rate cut", the corresponding numbers are [8, 9] and [2, 17] respectively. Then the positioning identifiers are divided into [8, 9] and [2, 17].

[0062] S310, obtaining fused positioning identifiers of all targets according to all positioning identifiers.

[0063] After obtaining the location identifier of each keyword, since the location identifiers contain and intersect each other, it is necessary to deduplicate these location identifiers to obtain target location identifiers without duplication and intersection.

[0064] It should be noted that not all target positioning identifiers are obtained by fusing multiple positioning identifiers. This is because all positioning identifiers include two types: positioning identifiers that meet the fusion conditions, and positioning identifiers that do not meet the fusion conditions. When the fusion conditions are not met, the positioning identifier is the target positioning identifier. When the fusion conditions are met, the positioning identifier needs to be fused to obtain the target positioning identifier.

[0065] In some embodiments of the keyword tagging method, Figure 2 As shown, all the fused target positioning identifiers are obtained based on all the positioning identifiers, including:

[0066] S311, sort all positioning identifiers.

[0067] In order to determine whether there is a positioning identifier that meets the fusion condition among numerous keywords, the positioning identifier of each keyword needs to be sorted.

[0068] In some implementations of the keyword tagging method, each location identifier corresponds to a start value and an end value; sorting all the location identifiers includes:

[0069] Step 1: Sort all positioning identifiers according to the starting value.

[0070] Step 2: Sort by the size of the starting value of the positioning identifier corresponding to each keyword. The sorting method can be descending or ascending, and there is no restriction here. The coded value corresponding to the first character in the keyword can be used as the starting value, and the coded value corresponding to the last character in the keyword can be used as the ending value.

[0071] Exemplarily, if the location identifier of a keyword is [8, 12], 8 is the starting value and 12 is the ending value.

[0072] S312, taking the first positioning identifier after sorting as the reference positioning identifier, and sequentially fusing the reference positioning identifier with the remaining positioning identifiers in the order of sorting to obtain all target positioning identifiers.

[0073] In some embodiments of the keyword tagging method, Figure 3 As shown, the first positioning mark after sorting is used as the reference positioning mark, and the reference positioning mark and the remaining positioning marks are merged in sequence according to the sorting order, including:

[0074] S3121, taking the first positioning identifier as the reference positioning identifier, and merging the reference positioning identifier with the next positioning identifier.

[0075] The fusion is performed in sequence according to the sorting order. Each time the fusion is performed, the current reference positioning identifier and the next positioning identifier are fused, and the fused positioning identifier becomes the new reference positioning identifier.

[0076] S3122: If the starting value of the next positioning marker is within the reference positioning marker, the ending value of the reference positioning marker is updated to the ending value of the next positioning marker to obtain a new reference positioning marker.

[0077] In this embodiment, the condition for the fusion of the current reference positioning identifier and the next positioning identifier is that "the starting value of the next positioning identifier is within the current reference positioning identifier". Once this condition is met, the current reference positioning identifier and the next positioning identifier are fused to obtain a fused positioning identifier, and the fused positioning identifier is used as the new reference positioning identifier, and then fused with the next positioning identifier based on the new reference positioning identifier.

[0078] For example, if the current reference positioning identifier is [2, 4] and a reference positioning identifier is [3, 6], then 3 is within [2, 4] and needs to be fused. The positioning identifier obtained after the fusion is [2, 6]. Then [2, 6] is used as the new reference positioning identifier, and [2, 6] is fused with the next positioning identifier until the last positioning identifier is fused.

[0079] It should be noted that each reference positioning identifier corresponds to the next positioning identifier. If the last positioning identifier and the corresponding reference positioning identifier meet the fusion condition, they are fused. If the fusion condition is not met, the last positioning identifier and the corresponding reference positioning identifier are both used as the target positioning identifier.

[0080] Exemplarily, if the current reference positioning identifier is [89, 102], and the next positioning identifier is [104, 105], and [104, 105] is the last positioning identifier, then both [89, 102] and [104, 105] are used as target positioning identifiers.

[0081] S3123: If the starting value of the next positioning identifier is not within the reference positioning identifier, the reference positioning identifier is used as the target positioning identifier, and the next positioning identifier is used as a new reference positioning identifier.

[0082] During the fusion process, there may be a situation where the current reference positioning marker and the next positioning marker do not meet the fusion conditions. At this time, the current reference positioning marker is used as the target positioning marker, and the next positioning marker is used as the new reference positioning marker to continue the fusion.

[0083] Exemplarily, if the current reference positioning marker is [52, 53] and the next positioning marker is [65, 66], [52, 53] is used as the target positioning marker, and [65, 66] is used as the new reference positioning marker, and then [65, 66] is merged with the next positioning marker.

[0084] S3124, continue to merge the new reference positioning markers until they are merged to the last positioning marker.

[0085] S3125, after the fusion is completed, the last positioning identifier is used as the target positioning identifier.

[0086] After the fusion is completed, there are two situations: first, the last positioning identifier is fused, in which case the positioning identifier obtained after the fusion of the last positioning identifier is used as the target positioning identifier. Second, the last positioning identifier is not fused, in which case the last positioning identifier is used as the target positioning identifier, and the reference positioning identifier corresponding to the last positioning identifier is also used as the target positioning identifier.

[0087] S410, marking the keywords corresponding to the target positioning identifier.

[0088] In order to facilitate quality inspection, the keywords corresponding to the target positioning identifier need to be marked so that the keywords can be highlighted later.

[0089] In some embodiments of the keyword tagging method, tagging the keyword corresponding to the target positioning identifier includes:

[0090] Step 1: Add tag labels to keywords corresponding to all target positioning identifiers to obtain tag text.

[0091] Step 2: When displaying the marked text, the words with the marked tags are rendered with a preset color.

[0092] The original text after adding the mark tag is used as the mark text. The preset color can be a single color, which is not limited here. Of course, the marked keywords can also be rendered with a preset font size.

[0093] The embodiment of the present application proposes a keyword tagging method, including: obtaining the original text, numbering the characters of the original text; extracting all the keywords in the original text, and obtaining the location identifier corresponding to each keyword, wherein the location identifier is composed based on the number of the characters in the keyword; according to all the location identifiers, all the fused target location identifiers are obtained; and the keywords corresponding to the target location identifiers are marked. The present application reduces the memory occupied during tagging and improves the tagging efficiency by numbering each character, then obtaining the location identifier of each keyword, and finally obtaining the target location identifier for tagging.

[0094] Another embodiment of the present application also provides a keyword tagging system 500, such as Figure 4 As shown, the keyword tagging system 500 includes:

[0095] The acquisition unit 510 is used to acquire the original text and number the characters of the original text.

[0096] The extraction unit 520 is used to extract all the keywords in the original text and obtain the location identifier corresponding to each keyword, wherein the location identifier is composed of the serial numbers of the characters in the keyword.

[0097] The fusion unit 530 is used to obtain fused positioning identifiers of all targets according to all positioning identifiers.

[0098] The marking unit 540 is used to mark the keywords corresponding to the target positioning identifier.

[0099] Furthermore, in some embodiments of the keyword tagging system, each positioning identifier corresponds to a start value and an end value; the fusion unit includes a sorting component and a merging component.

[0100] The sorting component is used to sort all positioning identifiers.

[0101] The merging component is used to take the first positioning identifier after sorting as the reference positioning identifier, and merge the reference positioning identifier and the remaining positioning identifiers in the sorting order to obtain all target positioning identifiers.
