Description

Input method, apparatus and medium

Technical Field

The embodiment of the invention relates to the technical field of input methods, in particular to an input method, an input device and a medium.

Background

The input method refers to a coding method adopted for inputting various characters into equipment (such as a computer, a mobile phone, a tablet computer and the like). The handwriting input method is an input method suitable for a touch screen device. Taking handwriting input of Chinese characters as an example, a user inputs Chinese character strokes by sliding on a touch screen device through a finger or a touch pen, the touch screen device recognizes characters formed by a group of Chinese character strokes as corresponding characters by recognizing the Chinese character strokes, and displays the characters in a certain font such as a song style and a regular script.

The current handwriting input process is generally as follows: the user inputs the characters one by one in the handwriting area, and waits and selects the single character candidate after one-time handwriting input is finished; after the user selects a single character candidate, the input method clears the handwriting area to continue the input of the next character.

The inventor finds that the current word-by-word input mode avoids the character segmentation problem of continuous handwriting recognition and has higher recognition rate in the process of implementing the embodiment of the invention; however, one handwriting input of the above-described character-by-character input mode can only realize input of one character, so that the handwriting input efficiency is low.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Current handwriting input methods typically employ a word-by-word input mode. The implementation process of the character-by-character input mode specifically comprises the following steps: after a user inputs track data of a character in a handwriting area, waiting and selecting single character candidates; after the user selects a single character candidate, the input method clears the handwriting area to continue the input of the next character. Since one-time handwriting input of the above-mentioned character-by-character input mode can only realize input of one character, the efficiency of handwriting input is low.

Aiming at the technical problem of how to improve the handwriting input efficiency, the embodiment of the invention provides an input scheme which can acquire track data input by a user; identifying the track data to obtain an identification character corresponding to the track data; determining and displaying the expansion candidate items corresponding to the recognition characters; the extension candidate may correspond to a language unit of a preset type, where the preset type specifically includes: sentence type.

The embodiment of the invention displays the language units of the sentence types as the expansion candidate items. The expansion candidate item of the sentence type can break through the limitation of only providing single word candidates and inputting word by word, and can provide more choices for the handwriting input of the user. Under the condition that the expansion candidate of the sentence type meets the requirements of the user, the handwriting input times of the user can be reduced, the operation cost of the user is saved, and therefore the handwriting input efficiency can be improved.

For example, in the case where the user inputs track data of "early", the embodiment of the present invention may provide expansion candidates of sentence types of "like all parents in the morning", "early" and the future ". The expansion candidate item can provide more choices for the handwriting input of the user, and under the condition that the expansion candidate item meets the requirements of the user, the handwriting input times of the user can be reduced, the operation cost of the user is saved, and therefore the handwriting input efficiency can be improved.

The embodiment of the invention can be applied to the Application environment of an input method APP (Application program), and can improve the handwriting input efficiency. In addition, the embodiment of the present invention may be applied to any input scenarios such as text editing, instant messaging, and web search, and it can be understood that the embodiment of the present invention does not limit the specific application environment and the specific input scenario.

The input method provided by the embodiment of the present invention can be applied to the application environment shown in fig. 1, as shown in fig. 1, the client 100 and the server 200 are located in a wired or wireless network, and the client 100 and the server 200 perform data interaction through the wired or wireless network.

The client 100 may run on a terminal with a touch screen, where the terminal specifically includes but is not limited to: smart phones, tablet computers, electronic book readers, MP3 (Moving Picture Experts Group Audio Layer III) players, MP4 (Moving Picture Experts Group Audio Layer IV) players, laptop portable computers, car-mounted computers, desktop computers, set-top boxes, smart televisions, wearable devices, and the like.

In practical applications, the client 100 may display an input interface, which may optionally include a handwriting area to receive trajectory data of the user via the handwriting area.

According to an embodiment, the client 100 may further obtain track data input by the user in the handwriting area, recognize the track data to obtain a recognition character corresponding to the track data, and determine and present an expansion candidate corresponding to the recognition character.

According to another embodiment, the client 100 may send the trajectory data input by the user in the handwriting area to the server, so that the server 200 recognizes the trajectory data to obtain the recognition character corresponding to the trajectory data, and determines the expansion candidate corresponding to the recognition character. It can be understood that the embodiment of the present invention does not limit the specific implementation subjects of recognizing the trajectory data and determining the expansion candidates corresponding to the recognition characters.

Method embodiment one

Referring to fig. 2, a flowchart illustrating steps of an input method according to an embodiment of the present invention is shown, which may specifically include the following steps:

step 201, acquiring track data input by a user;

step 202, identifying the track data to obtain an identification character corresponding to the track data;

step 203, determining and displaying the expansion candidate items corresponding to the recognition characters; the extension candidate may correspond to a language unit of a preset type, and the preset type may specifically include a sentence type.

The embodiment of the invention can be applied to the intelligent terminal with the touch screen, and in practical application, the track data input by the user can be acquired through the touch screen. Alternatively, the trace data may be generated by a finger or a stylus, and in particular, the path of movement of the finger or stylus on the input interface may form the trace data. In practical application, the track data generated by the finger or the touch pen can be sensed through a sensing device which is arranged in or out of the terminal. Optionally, the trajectory data may include: position coordinates of the trace points, etc.

In step 201, a sensing device may be used to sense the displacement and the lifting motion of the finger or the touch pen, and when the displacement of the finger or the touch pen is detected, the trajectory of the finger or the touch pen in the displacement process is recorded until the lifting motion of the finger or the touch pen is detected, and one lifting motion may correspond to one trajectory. In practical applications, the trajectory data may include: at least one track. For example, for a user not accustomed to a running stroke, the trace data corresponding to the word "rancour" may include 9 traces, and for a user accustomed to a running stroke, the trace data corresponding to the word "rancour" may include less than 9 traces. It is to be understood that the number of tracks included in the track data is not limited by the embodiment of the present invention.

In step 202, the trajectory data may be recognized using handwriting recognition techniques. HandWriting Recognition (HandWriting Recognition) refers to a process of converting ordered tracks generated during writing on a HandWriting device into Chinese character internal codes in an informationization manner.

In a specific implementation, for a character, the corresponding character code may be determined, and the mapping relationship between the character code and the character may be stored through a word stock. For handwriting input, the corresponding character code may be determined according to the font of the character, and it is understood that the specific character code is not limited in the embodiment of the present invention.

In the embodiment of the present invention, the process of identifying the Chinese character from the trajectory data may include: the method comprises the steps of identifying a character formed by a group of Chinese character strokes as a Chinese character code, inquiring a character library according to the Chinese character code, and obtaining the character corresponding to the Chinese character code from the character library. For the recognition process from the track data to the numbers, letters, symbols or other characters, the process is similar to the recognition process from the track data to the Chinese characters, so that the description is omitted and the mutual reference is only needed.

The handwriting input mode provided by the embodiment of the invention can comprise the following steps: a single write input mode, an overwrite input mode, or a line write input mode, etc. Wherein, the single-writing input mode takes all written tracks as the tracks of one character; the over-write input mode may support a track of one character overlaid on a track of another character; the line writing input mode can support continuous input of a plurality of characters and a certain distance is reserved between different characters. And if the user can select different handwriting input modes in advance, the input method determines the recognition characters corresponding to the track data according to the handwriting input mode selected by the user.

According to different handwriting input modes, the number of characters corresponding to the recognized character in the embodiment of the present invention may be one or greater than one.

Wherein, when the handwriting input mode is the single-writing input mode, the number of characters corresponding to the recognized character may be one. For example, if the user inputs the trajectory data of "early", the identification characters may be "early", "drought", and the like, and these identification characters include one character.

In the case that the handwriting input mode is the overlay or line writing input mode, the number of characters corresponding to the recognized character may be one or more than one. For example, if the user sequentially inputs the trajectory data of "early" and "up", the identification characters may be "early morning" and the like, and these identification characters include two characters.

It can be understood that the number of characters corresponding to the recognition character may correspond to the trajectory data, and the number of characters corresponding to the recognition character is not limited in the embodiment of the present invention.

In practical applications, the recognition character itself may be a candidate. For convenience, the candidate word corresponding to the recognition character itself may be recorded as a common candidate.

In step 203, the expanded candidate may be used as a supplement to the general candidate, so as to increase information of the candidate, and further increase the selection chance of the user for the candidate.

In particular, the preset types of the expansion candidates may specifically include: the word type, the phrase type, the sentence type and the like can realize the input of a plurality of characters through one input operation under the condition that the expansion candidate items of the preset type meet the requirements of the user, so the input times of the user can be reduced.

The phrase refers to a certain combination relationship of two or more words. The sentence is a basic unit for language application, is composed of words and phrases, can express a complete meaning, such as telling others about a thing, proposing a problem, expressing a requirement or a stop, expressing a certain probability of feeling, and expressing the continuation or omission of a section of speech. The expansion candidate item of the sentence type of the embodiment of the invention can express a complete meaning and can effectively save the input times of the user.

The embodiment of the invention can provide the following technical scheme for determining the expansion candidate item corresponding to the recognition character:

the technical scheme 1,

In technical solution 1, the determining and presenting the expansion candidate corresponding to the recognition character may specifically include:

searching language units of a preset type in a word stock by taking the identification characters as prefixes; and/or

And searching a language unit of a preset type in a word stock by taking the identification character and the corresponding text as prefixes.

In practical applications, the word stock may specifically include: at least one of a system thesaurus, a user thesaurus and a cell thesaurus.

The word stock of the system can be a word stock provided by the input method, and can be a local word stock of the terminal, or a network word stock or a cloud word stock acquired by the input method from a server. Typically, the system thesaurus provided by the same input method to different users is the same.

The user word bank is a word bank relative to the system word bank, the same content is provided for different users relative to the system word bank, and the input method can store the entry on the screen (the entry on the screen after the action of the entry on the screen) input by the user into the user word bank by learning words. Typically, the system lexicon provided by the same input method to different users is different.

A cell word bank is a vocabulary set of a fine category, and the category of the cell word bank can be a professional field (such as a medical field word bank), a region (such as a Beijing place name word bank), a game (such as a magic animal world vocabulary) and the like;

it is understood that the system thesaurus, the user thesaurus and the cell thesaurus are only examples of thesaurus, and the embodiment of the present invention is not limited to the specific thesaurus.

In a specific implementation, the characters can be recognized as prefixes, and language units of preset types are searched in a word stock. The language unit may correspond to a unit of a language, and the language unit may correspond to a word, a phrase, or a sentence. Where a word may represent a single word, a phrase may represent a combination of multiple words.

For example, in the case that the recognized character is "early", the embodiment of the present invention may obtain the following search result based on the search of the lexicon: language units of word types such as "morning", "morning" and "breakfast" and "morning" and language units of sentence types such as "morning and" morning are good "and" morning and "future" and the like.

In one implementation, the search result may be directly used as an extension candidate corresponding to the recognition character. For example, when the number of search results is small, the search results may be directly used as the expansion candidates corresponding to the recognition characters.

In another implementation, the expansion candidate may be selected from the search results. Correspondingly, the determining and presenting the expansion candidate corresponding to the recognition character may further include: and selecting the expansion candidate items from the search result according to the use frequency.

The use frequency is used for representing the use times of the user for the search result. In the field of input methods, the frequency of use can be characterized by word frequency. The word frequency can represent the input times of the user for the entry corresponding to the search result, and the word frequency can be recorded as a parameter of the word bank. According to the embodiment of the invention, the expansion candidate item is selected from the search result according to the use frequency, and a more common expansion candidate item can be provided for the user, so that the matching degree between the expansion candidate item and the user requirement can be improved.

In practical application, the expansion candidate item whose usage frequency meets the first preset condition may be selected from the search result. The first preset condition may include: the usage frequency exceeds a frequency threshold, or the usage frequency is ranked N (N is a positive integer) bits first, and the like. Wherein, the search results can be ranked according to the order of the use frequency from high to low.

In an alternative embodiment, the expansion candidate items may be selected from the search results for a plurality of preset types, respectively. For example, for a word type, i expansion candidate items are selected from the search result; for another example, j expansion candidate items are selected from the search result aiming at the phrase type; as another example, k expansion candidates are selected from the search result for the sentence type, and so on. In this embodiment, i, j, and k may be positive integers, for example, the ranges of i, j, and k may be 1 to 3, and it is understood that the specific number of the corresponding expansion candidates is not limited in the embodiment of the present invention.

For example, in the case that the recognition character is "early", the embodiment of the present invention may select "morning", "early" from the search result for the word type; aiming at the phrase type, selecting 'good morning' from the search result; and aiming at the sentence types, selecting ' morning good like ' parents ', ' morning good, future ' and the like from the search results.

Technical scheme 2,

In technical solution 2, the number of identifiers may be multiple, and the determining and presenting the expansion candidates corresponding to the identifier may specifically include: selecting a target recognition character from the plurality of recognition characters according to the scores of the recognition characters; and determining and displaying the expansion candidate items corresponding to the target recognition characters.

Technical means 2 selects a target recognition character from a plurality of recognition characters based on the score of the recognition character. The score can represent the quality of the recognition character, so that a target recognition character with higher quality can be selected from a plurality of recognition characters, and an expansion candidate item is provided for the target recognition character, so that the matching degree between the expansion candidate item and the user requirement can be improved.

In a particular implementation, the score of the recognized character may be determined based on a degree of match between the recognized character and the trajectory data. In general, the higher the degree of matching between the recognition character and the trajectory data, the higher the score of the recognition character.

In practical application, the expansion candidate item with the score meeting the second preset condition may be selected from the search result. The second preset condition may include: the score exceeds a score threshold, or the score is ranked M top (M is a positive integer), and so on. Wherein the recognized characters may be ranked in order of scores from high to low. For example, the recognition character having the highest score may be selected as the target recognition character.

After the target recognition character is determined, the expansion candidate corresponding to the target recognition character can be determined and displayed by using the technical scheme 1. In other words, a combination of the technical solution 1 and the technical solution 2 can be adopted by those skilled in the art according to the actual application requirements.

In the process of presenting the expansion candidate items, the embodiment of the invention can present one of three preset types, or two or three types. For example, one of the expansion candidates of the sentence type may be presented. As another example, expansion candidates for sentence types and word types may be presented. As another example, expansion candidates for sentence type and phrase type may be presented. Alternatively, expansion candidates for sentence types, word types, and phrase types may be presented.

Also, presentation positions of extension candidates of different preset types may have different priorities. For example, a word type has a higher priority than a phrase type, which has a higher priority than a sentence type.

In a specific implementation, the extended candidate of the word type may be presented in front of the extended candidate of the word group type or the sentence type; and/or, showing the expansion candidate item of the phrase type in front of the expansion candidate item of the sentence type.

In practical application, common candidate items corresponding to the recognition characters can be displayed; the above-mentioned common candidate may be located in front of the extended candidate. For example, in order from front to back, the presented candidates may include in order: a common candidate item and an extended candidate item; wherein, in order from front to back, the expansion candidates may sequentially include: an extended candidate of a word type, an extended candidate of a phrase type, and an extended candidate of a sentence type.

In one implementation, the candidate region may include: the display device comprises a first area and a second area, wherein the first area and the second area are arranged up and down, and the first area is positioned above the second area. Wherein the first region may exhibit in sequence: the common candidate, the extended candidate of the word type, and the extended candidate of the phrase type, and the second region may show: the sentence type expansion candidates, of course, the above implementation is only an example, and in practice, the common candidates and the expansion candidates may be arranged in sequence from front to back and from top to bottom according to the specific sizes of the first region and the second region.

It should be noted that common candidates in the embodiments of the present invention specifically include: target recognition characters and non-target recognition characters. In practical applications, the target recognition character may be presented in front of the expansion candidate. For non-target recognition characters, they may not be presented, or they may be presented after the expansion candidates.

To sum up, the input method of the embodiment of the present invention displays the language units of the sentence types as the expansion candidates. The expansion candidate items of the sentence types can express a complete meaning, and can break through the limitation of only providing single word candidates and inputting word by word, thereby providing more choices for the handwriting input of the user. Under the condition that the expansion candidate of the sentence type meets the requirements of the user, the handwriting input times of the user can be reduced, the operation cost of the user is saved, and therefore the handwriting input efficiency can be improved.

Method embodiment two

Referring to fig. 3, a flowchart illustrating steps of an input method according to an embodiment of the present invention is shown, which may specifically include the following steps:

301, acquiring trajectory data input by a user;

step 302, identifying the track data to obtain a plurality of identification characters corresponding to the track data;

step 303, judging whether a target recognition character meeting a second preset condition exists in the plurality of recognition characters, if so, executing step 304, otherwise, executing step 306;

step 304, determining an expansion candidate item corresponding to the target recognition character;

the extension candidate may correspond to a language unit of a preset type, and the preset type may specifically include at least one of the following types: word type, phrase type, and sentence type.

Step 305, displaying the target recognition character and the expansion candidate item; wherein the target recognition character is located in front of the expansion candidate item;

and step 306, displaying the plurality of recognition characters according to the sequence of the scores from high to low.

The embodiment of the invention identifies the track data and can obtain a plurality of corresponding identification characters. For example, when the user inputs the trajectory data of "early", a plurality of recognized characters such as "early", "drought", and the like can be obtained.

When a target recognition character meeting a second preset condition exists in the plurality of recognition characters, a corresponding expansion candidate item can be determined for the target recognition character, and the target recognition character and the expansion candidate item are displayed. The second preset condition can improve the matching degree between the target recognition character and the track data, namely the matching degree between the target recognition character and the user requirement. On the basis, the expansion candidate item is provided for the target recognition character, and the matching degree between the expansion candidate item and the user requirement can be improved.

In this case, the non-target recognition character can be displayed. For example, non-target recognition characters may be presented behind the expansion candidates. As another example, non-target recognition characters may be presented between the target recognition characters and the expansion candidates. As another example, non-target recognition characters may be presented between different preset types of expansion candidates. It will be appreciated that it is also possible that non-target recognition characters are not presented.

In the case that there is no target recognition character meeting the second preset condition among the plurality of recognition characters, the plurality of recognition characters may be presented in an order of scores from high to low according to a conventional flow.

It should be noted that, for simplicity of description, the method embodiments are described as a series of motion combinations, but those skilled in the art should understand that the present invention is not limited by the described motion sequences, because some steps may be performed in other sequences or simultaneously according to the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no moving act is required as an embodiment of the invention.
