Note that, the terminal apparatuses 101, 102, and 103 may directly perform operations such as updating and managing a lexicon, and in this case, the server 105 and the network 104 may not be present.
It should be noted that the character string replacement method provided in the embodiment of the present application is generally executed by the terminal devices 101, 102, and 103, and accordingly, the character string replacement apparatus is generally disposed in the terminal devices 101, 102, and 103.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a string replacement method according to the present application is shown. The character string replacing method comprises the following steps:
In this embodiment, an electronic device (for example, the terminal devices 101, 102, and 103 shown in fig. 1) on which the character string replacement method operates may be provided with a clipboard in which a clipboard character string copied in advance by a user may be stored. The electronic device may further display a text, and when a user selects a certain region or paragraph in the displayed text, the electronic device may determine the region or paragraph selected by the user as a target text. In practice, the clipboard is an area in the memory, and information can be transferred and shared between various applications.
In this embodiment, in response to detecting a pointing operation of the user to the target text, the electronic device may extract a character string in the target text within a preset range of a position pointed by the user, determine the extracted character string as a character string to be replaced, and extract a clip character string stored in a clipboard in advance. Here, the pointing operation may be an operation of moving a mouse pointer or a cursor to a certain position in the target text, or an operation of clicking or pressing a certain position in the target text displayed on a touch panel of the electronic device by a user. It should be noted that the preset range may be a range formed by a preset number of characters (for example, 5 or 10 characters) before and after the position pointed by the user. As an example, the target text is "small edited here brings you ten taboos of wearing small girls", the user pointing position is the position where the character "woman" is located, the preset range is the range of a character string composed of 3 characters before and after the position pointed by the user, and the character string in the preset range is "small girls wearing clothes".
In this embodiment, the electronic device may perform word segmentation on the clipped character string by using various word segmentation methods to generate a clipped word set, and perform word segmentation on the character string to be replaced to generate a word set to be replaced.
In some optional implementations of this embodiment, the word segmentation method may be a statistical-based word segmentation method. Specifically, the frequency of a character combination formed by adjacent characters in the clipped character string and the character string to be replaced may be counted, and the frequency of occurrence of the character combination may be calculated. And when the frequency is higher than a preset frequency threshold value, judging that the combination forms a word, thereby realizing word segmentation of the cut and pasted character string and the character string to be replaced.
In some optional implementation manners of this embodiment, the word segmentation method may also be a word segmentation method based on a character string matching principle. Specifically, the clipped character string and the character string to be replaced may be respectively matched with each word in a machine dictionary preset in the electronic device by using a character string matching principle, where the character string matching principle may be a forward maximum matching method, a reverse maximum matching method, a segmentation labeling method, a word-by-word traversal matching method, a forward optimal matching method, or a reverse optimal matching method.
In some optional implementations of the embodiment, the electronic device may perform word segmentation on the clipped character string and the to-be-replaced character string by using a Hidden Markov Model (HMM). Taking word segmentation of the clipped character string as an example, the electronic device may first determine a quintuple that forms the markov model, where the quintuple includes an observable sequence, a hidden state set, an initial state space probability, a state transition matrix, and an observation probability distribution matrix. Wherein the observable sequence is the clip character string; the hidden state set can comprise four states of single word formation, prefix, word middle and word end; the initial state space probability may be an initial probability distribution of each state in the hidden state set in a preset lexicon; the state transition matrix may be used to represent a state transition probability (e.g., a probability of converting from a prefix to a word) of each character in the clipped character string; the observed probability distribution matrix is used to characterize the probability of each character in each state. Then, the electronic device may label a state for each character, and determine a maximum probability state of each character based on a viterbi algorithm. Finally, based on the maximum probability state of each character, the cut-and-pasted character strings are segmented, and a cut-and-pasted word set is obtained.
It should be noted that the above word segmentation methods are well-known technologies that are widely researched and applied at present, and are not described herein again.
In this embodiment, the electronic device may analyze the clipped word set and the to-be-replaced word set by using various analysis methods, and determine a target clipped word in the clipped word set and a target to-be-replaced word in the to-be-replaced word set, which is matched with the target clipped word. As an example, the electronic device may determine similarity between each clipped word and each replacement word by performing similarity calculation between words in the clipped word set and words in the to-be-replaced word set, determine the clipped word in a group of words with the highest similarity as a target clipped word, and determine the to-be-replaced word in the group of words as the target to-be-replaced word; in addition, the electronic device may further determine a word scrap word in the word scrap word set input or selected by the user as a target scrap word, and determine a word in the word to be replaced set input or selected by the user as a target word to be replaced matched with the target scrap word.
In some optional implementation manners of this embodiment, a plurality of similar phrases preset by a user may be stored in the electronic device in advance, where each of the similar phrases includes a plurality of words of mutually similar words. For example, a certain similar phrase includes the word "like" and the word "like", another similar phrase includes the word "short" and the word "small", and so on. The electronic device may extract the preset plurality of similar phrases, and for each clip word in the clip word set, the following steps may be performed:
first, a near-meaning phrase in the plurality of near-meaning phrases, in which a word matching the clip word exists, may be determined as a target near-meaning phrase. As an example, the above-mentioned plurality of similar phrases are a first similar phrase composed of the word "like" and the word "like", and a second similar phrase composed of the word "short child" and the word "small child", respectively. The above-mentioned clipword set contains the clipword "short child". The electronic device can match the cut-and-pasted word "short child" with the words in the first similar phrase and the second similar phrase one by one. In this example, there is a word matching the clipword "short child" in the second similar phrase, so for the clipword "short child", the second similar phrase may be determined as the target similar phrase corresponding to the clipword "short child".
Then, the electronic device may match each word to be replaced in the set of words to be replaced with a word in the target synonym phrase, except for the clipped word, one by one. Taking the above example as an example, the word set to be replaced may include the word "kid" to be replaced, the word "girl" to be replaced, and the word "dressing". The electronic device may match the word to be replaced "boy", the word to be replaced "girl", and the word to be replaced "dressing" with the word (i.e., the word "boy") other than the word "short" in the second similar phrase one by one.
Finally, in response to determining that there is a word to be replaced successfully matched in the set of words to be replaced, the electronic device may determine the determined word to be replaced successfully matched as a target word to be replaced matched with the clipped word, and determine the clipped word as a target clipped word. Taking the above example as an example, the target similar phrase corresponding to the clip word "short child" is the second similar phrase. After matching the word to be replaced "boy", the word to be replaced "girl", and the word to be replaced "dressing" in the word set to be replaced one by one with the word "boy" in the second similar word group, the electronic device may determine that the word to be replaced "boy" successfully matched exists in the word set to be replaced. The electronic device may determine the word to be replaced "small child" as a target word to be replaced that matches the clipping word "short child", and determine the clipping word "small child" as a target clipping word.
In some optional implementation manners of this embodiment, a plurality of similar phrases preset by a user may be stored in the electronic device in advance, where each of the plurality of similar phrases includes a plurality of words belonging to a same type. For example, a generic phrase includes the word "Integer" and the word "String" for indicating the type of variable, another generic phrase includes the word "apple" and the word "watermelon" belonging to fruit, and so on. It should be noted that, a plurality of words belonging to the same type in each similar phrase may also be a plurality of words preset by the user for describing the same object, for example, a similar phrase includes the word "red apple" and the word "green apple". The electronic device may extract the preset plurality of similar phrases, and for each clip word in the clip word set, the following steps may be performed: firstly, a plurality of preset similar phrases can be extracted; and then, regarding each clip word in the clip word set, taking the same-kind word group in the plurality of same-kind word groups in which the word matched with the clip word exists as a target same-kind word group, matching each word to be replaced in the set of words to be replaced one by one with the words except for the clip word in the target same-kind word group, responding to the determination that the word to be replaced successfully matches exists in the set of words to be replaced, determining the determined word to be replaced successfully matching as the target word to be replaced matched with the clip word, and determining the clip word as the target clip word. It should be noted that the method for determining the target clip word and the target to-be-replaced word based on the similar phrases is substantially the same as the method for determining the target clip word and the target to-be-replaced word based on the synonymous phrases, and is not described herein again.
And step 204, replacing the target word to be replaced in the character string to be replaced with the target cut-and-pasted word.
In this embodiment, the electronic device may replace a target word to be replaced in the character string to be replaced with a corresponding target clip word. As an example, the character string to be replaced is "small girl dresses", the target word to be replaced is "small", the target clip word is "short", and the electronic device may replace the character string "small" in the character string "small girl dresses" to be replaced with "short", so as to obtain a replaced character string "short girl dresses".
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the character string replacement method according to the present embodiment. In the application scenario of fig. 3, the user first selects the target text 301 and points to the location of the character "woman" in the target text 301. Then, the terminal device extracts a character string in a range formed by three characters before and after the position pointed by the user in the target text 301, that is, a character string "little girl dresses", determines the character string "little girl dresses" as a character string to be replaced, and extracts a clip character string stored in the clipboard in advance. And then, the terminal equipment divides words of the cut and pasted character string 'short child classmates' and the character string to be replaced 'small child girl dresses' respectively to generate a cut and pasted word set and a word set to be replaced. Then, the terminal device analyzes the clipped word set and the to-be-replaced word set, and determines a target clipped word "short child" in the clipped word set and a target to-be-replaced word "small child" in the to-be-replaced word set, which is matched with the target clipped word. And finally, replacing the target to-be-replaced word 'small children' in the to-be-replaced character string 'small girls dressing' with the target cut and pasted word 'short children'.
The method provided by the embodiment of the application, in response to detecting that a user performs an operation on a target text, extracts a character string in the target text within a preset range of a position pointed by the user, determines the extracted character string as a character string to be replaced, performs word segmentation on the extracted clipped character string and the extracted character string to be replaced, which are stored in a clipboard in advance, so as to generate a clipped word set and a word set to be replaced respectively, analyzes the clipped word set and the word set to be replaced, determines a target clipped word and a target word to be replaced, and finally replaces the target word to be replaced in the character string to be replaced with the target clipped word, so that manual editing and replacement are not required, the labor cost is reduced, and the text processing efficiency is improved.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a string replacement method is shown. The process 400 of the character string replacement method includes the following steps:
In this embodiment, an electronic device (for example, the terminal devices 101, 102, and 103 shown in fig. 1) on which the character string replacement method operates may be provided with a clipboard in which a clipboard character string copied in advance by a user may be stored. The electronic device may further display a text, and when a user selects a certain region or paragraph in the displayed text, the electronic device may determine the region or paragraph selected by the user as a target text. In response to detecting a pointing operation of the user to the target text, the electronic device may extract a character string in the target text within a preset range of a position pointed by the user, determine the extracted character string as a character string to be replaced, and extract a clip character string stored in a clipboard in advance.
In this embodiment, the electronic device may perform word segmentation on the clipped character string by using various word segmentation methods to generate a clipped word set, and perform word segmentation on the character string to be replaced to generate a word set to be replaced. For example, the electronic device may perform segmentation of the clipped character string and the character string to be replaced by using a hidden markov model.
In this embodiment, the electronic device may determine a word vector of each clipped word in the clipped word set and a word vector of each word to be replaced in the word set to be replaced. In practice, a word vector may be a vector used to represent word features, with the values of each dimension of the word vector representing a feature having certain semantic and grammatical interpretations. Here, the electronic device may determine a word vector of each word to be replaced by using various word vector calculation tools (e.g., word2vec, etc.) using an open source.
in this embodiment, for each clipboard word in the clipboard word set, the electronic device may use a word vector of the clipboard word as a target word vector, determine similarity between the target word vector and word vectors of respective words to be replaced by using various similarity calculation methods (e.g., a similarity calculation method based on euclidean distance, a cosine similarity calculation method, etc.) or an open-source word vector calculation tool (e.g., word2vec, etc.), in response to determining that a word to be replaced exists in the set of words to be replaced whose similarity between the word vector and the target word vector is greater than a preset similarity threshold, may determine the clipboard word as a designated clipboard word, determine the determined word to be replaced as a designated word to be replaced that matches the designated clipboard word, and perform the operation in step 405 or step 406. It should be noted that the above method for generating a word vector and the method for calculating the similarity of a word vector are well-known technologies that are widely researched and applied at present, and are not described herein again.
In this embodiment, for each determined designated clip word, the electronic device may determine, based on a preset near-meaning phrase, whether the designated clip word and a designated to-be-replaced word matched with the designated clip word are mutually near-meaning words, if so, determine the designated to-be-replaced word matched with the designated clip word as a target to-be-replaced word, and determine the designated clip word as the target clip word. In practice, for each determined designated clipword, if the designated clipword and the designated word to be replaced matched with the designated clipword belong to the same synonym phrase, the electronic device may determine that the designated clipword and the designated word to be replaced matched with the designated clipword are synonyms.
In this embodiment, for each determined designated clip word, the electronic device may determine, based on a preset homogeneous phrase, whether the designated clip word and a designated word to be replaced matched with the designated clip word belong to the same type, if so, determine the designated word to be replaced matched with the designated clip word as a target word to be replaced, and determine the designated clip word as the target clip word. In practice, for each determined designated clipword, if the designated clipword and the designated word to be replaced matched with the designated clipword belong to the same phrase group, the electronic device may determine that the designated clipword and the designated word to be replaced matched with the designated clipword are words of the same kind.
It should be noted that, for each determined specified clipword, in response to determining that the specified clipword and the specified to-be-replaced word matched with the specified clipword do not belong to the same similar phrase and do not belong to the same similar phrase, the electronic device may generate a similar phrase formed by the specified clipword and the specified to-be-replaced word matched with the specified clipword, and replace the specified to-be-replaced word matched with the specified clipword in the character string to be replaced with the specified clipword.
In this embodiment, the electronic device may replace a target word to be replaced in the character string to be replaced with a corresponding target clip word.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the character string replacement method in this embodiment highlights the parsing steps of the clipped word set and the word set to be replaced.
