Technical Field

The present application relates to the field of terminal technologies, and in particular, to a one-handed operation method, an apparatus, a terminal, and a storage medium.

Background

With the continuous development of terminal technology, large-size screens are increasingly applied to terminals. However, as the screen size increases, the difficulty of one-handed operation increases. For example, for a mobile phone with a large-size screen, when a user performs a one-handed operation, the user cannot control the mobile phone through the one-handed operation because the fingers cannot cover the entire area of the screen.

In the related art, in order to facilitate a user to operate the terminal with a single hand, the terminal provides a single-hand operation mode, and in the single-hand operation mode, the terminal may reduce a display interface of the screen and display the reduced display interface in a left area or a right area of the screen, so that the user can operate on the reduced display interface with the single hand.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Before explaining the embodiments of the present application in detail, an application scenario of the embodiments of the present application will be described. The method and the device are applied to scenes needing to operate the terminal with one hand, for example, scenes needing to operate the terminal with a large-size screen with one hand. The terminal can be a mobile phone or a tablet computer.

Fig. 1 is a flowchart of a one-handed operation method provided in an embodiment of the present application, where the method is applied to a terminal, and the terminal may be a mobile phone or a tablet computer, as shown in fig. 1, the method includes the following steps:

step 101: and displaying a floating selector on the upper layer of the display interface, wherein the floating selector is used for selecting a target display item from the display items included in the display interface.

It should be noted that the display interface may be a main interface of the terminal or other display interfaces, and may also be an application page or a web page. The presentation item may be an interface element and/or text. Interface elements refer to various elements in a display interface, such as icons, controls, buttons, pictures, or links. The text may be a text directly displayed in the display interface, or may also be a text in a picture displayed in the display interface, which is not limited in the embodiment of the present application.

In addition, the target display item is a display item selected from the display interface, and can be any display item in the display interface. For example, the target presentation item is any presentation item outside the area covered by the floating selector, or any presentation item covered by the floating selector. That is, any display item can be selected from the display interface through the floating selector, so that flexible selection of remote display items is realized, and the user can conveniently perform one-hand operation.

Furthermore, the floating selector is displayed on the upper layer of the display interface in a floating mode and can move on the display interface. For example, the display interface may be moved according to a drag operation by the user. Of course, the movement may be performed according to other trigger operations.

In addition, the floating selector can be displayed on the upper layer of the display interface by default, namely, the floating selector is automatically displayed on the upper layer of the display interface after the user opens the display interface. Or, the upper layer of the display interface does not display the floating selector first, and then the floating selector is triggered and displayed according to the user's call-up operation. The call-up operation may include a click operation, a touch operation, a voice operation, a gesture operation, or the like, which is not limited in this embodiment of the present application. That is, when the floating selector is not displayed on the display interface, if the call-up operation for the floating selector is detected based on the display interface, the floating selector can be displayed on the upper layer of the display interface.

As an example, the call-out operation may be an operation of holding down a certain position of the display interface and lightly shaking the terminal. For example, when the floating selector is not displayed on the display interface, if a pressing operation on the display interface is detected and a swing operation on the current terminal is detected, the floating selector is displayed on the upper layer of the pressing position of the pressing operation. Thus, referring to fig. 2, if the user wants to invoke the floating selector, the user can press the edge area of the display interface with the thumb and shake the terminal from side to side, so that the floating selector can be called from the pressed position of the user, and the floating selector is displayed at the pressed position of the user.

The pressing position of the pressing operation can be any position of the display interface, and is generally a position which can be touched by a user under the operation of one hand. In addition, the pressing position of the pressing operation may be located in a preset designated position area, for example, the designated position area may be an edge area of the display interface.

As an example, in the case where a floating selector is displayed on the display interface, a selection focus corresponding to the floating selector may also be displayed on the display interface. The selection focus is used for selecting the display item on the display interface, namely the selected target display item can be determined according to the position of the selection focus. The floating selector may control the selection focus to move on the display interface to determine the target presentation item based on a position of the moved selection focus.

As an example, the selection focus may be displayed in the form of a cursor, an arrow, or the like, and may be moved on the display interface according to a user operation, and the target presentation item may be selected from the display interface by moving the selection focus.

As an example, when a floating selector and a selection focus are displayed on a display interface, if a movement instruction for the selection focus is received based on the floating selector, the selection focus may be controlled to move on the display interface according to the movement instruction, and then a display item corresponding to a position where the moved selection focus is located is determined as a target display item.

As one example, the floating selector may also include a direction selection button that may be used to control the direction in which the presentation item is selected, i.e., along which direction of the display interface the presentation item is selected. In this manner, the user may be facilitated to select a presentation item from various directions.

As an example, in the case where the floating selector further includes a direction selection button, a pointing axis extends from the direction selection button in a direction away from the direction selection button, and the selection focus is located on the pointing axis and can be moved along the pointing axis. The direction selection button can be used for controlling the pointing axis to rotate around the direction selection button as a center and controlling the selection focus to move on the pointing axis.

The display item intersected with the pointing axis can be used as an alternative display item, and the selection focus can be moved on the pointing axis, so that switching can be performed between different alternative display items. And the alternative display item at the position of the selection focus is the selected target display item.

As one example, presentation items that intersect the pointing axis may be highlighted in a first form and alternate presentation items that select where the focus is located may be highlighted in a second form. Wherein the first form is different from the second form. For example, the display items intersecting the pointing axis are highlighted with a thin line box, and the alternative display items at the position of the selection focus are highlighted with a thick line box.

As an example, the user may change the direction of the pointing axis by rotating the direction selection button, and control the selection focus to move on the pointing axis by clicking the direction rotation button. In the process that the selection focus moves on the pointing axis, the display item at the position of the selection focus can be used as the selected target display item, and the selected target display item can be switched along the pointing axis by moving the selection focus.

As an example, if the terminal detects a rotation instruction based on the direction selection button, the pointing axis is controlled to rotate around the direction selection button according to the rotation direction indicated by the rotation instruction; after the pointing axis stops rotating, if a movement instruction is detected based on the direction selection button, controlling the selection focus to move on the pointing axis according to the movement direction indicated by the movement instruction; and determining the display item corresponding to the position of the moved selection focus as a target display item.

As an example, by default, the pointing axis would point to a presentation item that is farthest away, and the direction selection button would be highlighted. The user taps the directional selection button and can switch different presentation items along the pointing axis.

As one example, the pointing axis is shown in dashed line form, and the selection focus is a cursor on the pointing axis.

As an example, please refer to fig. 3, fig. 3 is a schematic diagram of a floating selector 30 provided in an embodiment of the present application, and as shown in fig. 3, the floating selector 30 includes a circular ring area 31 and an inner circular area 32 inside the circular ring area. The inner circle region 32 is a display region, and the ring region 31 includes two direction selection buttons at opposite positions. Further, a pointing axis 33 extends from the direction selection button in a direction away from the direction selection button, and the selection focus 34 is located on the pointing axis and can move along the pointing axis.

As an example, the floating selector may further have a free selection mode, in which a selection focus corresponding to the floating selector is displayed on the display interface, and the user may control the selection focus to move freely on the display interface according to a sliding direction of the sliding operation through an operation on the display interface, and further freely select the display item in the interface through the movement of the selection focus.

As an example, a selection focus corresponding to the floating selector is displayed on the display interface, and if a sliding instruction is detected based on the display interface, the selection focus is controlled to move on the display interface according to the sliding direction indicated by the sliding instruction; and determining the display item corresponding to the position of the moved selection focus as a target display item.

As one example, the floating selector may also have a move option displayed thereon for moving the floating selector. For example, when a drag operation on a move option is detected, the floating selector is moved in accordance with the drag direction of the drag operation. In this manner, the user may drag the floating selector to any location on the display interface by dragging the move option. Wherein the movement option can be displayed at any position of the floating selector. For example, at the border of the floating selector. Referring to fig. 3, a move option 35 is displayed on the floating selector 30.

As an example, the floating selector may also have a close option displayed thereon for closing the floating selector, i.e., hiding the floating selector. The user may close the floating selector by clicking on the close option. Referring to fig. 3, a close option 36 is displayed on the float selector 30.

As one example, the floating selector further includes a mode switch option for switching a selection mode of the floating selector, the selection mode including an element selection mode for selecting an interface element from the display interface and a text selection mode for selecting text from the display interface. For example, the user may switch the selection mode of the floating selector by clicking on a mode switch option.

Step 102: and displaying the alternate display item in the display area of the floating selector, wherein the alternate display item is obtained by copying according to the target display item.

After the target display item is selected from the display interface through the floating selector, the floating selector can display the alternate display item of the target display item in the display area of the floating selector, so that the user can operate the target display item through the operation of the alternate display item.

For example, referring to FIG. 3, after selecting the interface element "perimeter tour/travel" at the selection focus, the substitute element "perimeter tour/travel" may be displayed in the display area of the floating selector.

In addition, in the case where the floating selector is in the text selection mode, a text selection list may also be displayed in the display area of the floating selector. The text selection list comprises a plurality of levels of text fragment thumbnail information, the plurality of levels of text fragments are text fragments in a text displayed on the display interface, and the text ranges of the plurality of levels of text fragments are sequentially increased. The thumbnail information of the text passage of the plurality of levels is an alternate display item of the text passage of the plurality of levels.

As an example, in the case that a selection focus is further displayed on the upper layer of the display interface, and the floating selector is used for controlling the selection focus to move on the display interface, if the selection focus reaches the edge of the screen, the relevant display item of the edge of the screen can also be evoked. For example, if the selection focus reaches the edge of the screen, a display item that can be called by a sliding operation of the edge of the screen may be determined, and then the display item corresponding to the sliding operation of the edge of the screen may be displayed in the display area.

As one example, a presentation item that can be evoked by a slide operation at the edge of the screen refers to a presentation item that can be evoked by an operation of sliding from the edge of the screen toward the inside of the screen. Such as sliding an evoked notification bar or setting options from top to bottom of the screen. In addition, when the selection focus reaches the edge of the screen, a flashing line can be displayed at the edge of the screen to remind the user that the current selection focus reaches the edge of the screen.

The screen edge has special purpose, when sliding from outside to inside, it can trigger many functions, but the edge itself has no visible interface elements in the screen. In order to enable the user to conveniently operate the invisible elements, the floating selector can automatically detect the edge of the screen, when the selected focus reaches the edge of the screen, a flashing line is displayed at the edge, and a function name which can be called by the sliding operation of the edge of the screen can be automatically displayed in the display area of the floating selector, so that the user can operate the function name.

As an example, in general, the presentation item evoked by the sliding operation of the screen edge may include the following four cases:

1) and sliding the screen from top to bottom above the screen to call out system functions and message notification. .

2) And (4) sliding from bottom to top below the screen to call out the quick function customized by the system.

3) And sliding the left side of the screen to the right and left, and returning to the previous page.

4) And the right side of the screen slides from left to right and advances to the next page.

In another embodiment, if there are no selectable display items in the entire display page, the floating selector is invoked without selecting any display item by default, the selection focus is not displayed in the display page, and there is no content in the display area of the floating selector, which is in an invalid state. When the edge of the screen is selected forcibly, if no triggerable behavior exists at the edge, the state is also invalid.

Step 103: and if the first operation event of the substitute display item is detected, simulating a second operation event aiming at the target display item according to the first operation event.

After the floating selector displays the alternate representation item, the user can operate the alternate representation item, for example, tap, drag, long press, multi-finger touch, and the like. And after the user operates the substitute presentation item, the terminal can create a simulated second operation event according to the first operation event aiming at the substitute presentation item.

In addition, if the screen supports recognition of multiple pressures, the pressure operation with different strength for the substitute display item can be reflected on the target display item.

When the user performs any operation on the avatar presentation item, a simulation event (second operation event) for the target presentation item can be immediately created. The simulation event needs to copy the data of the original event in real time, including the event type, the carried data, the coordinate needing to be changed, and the like of the original event. After the simulation event is created, the simulation event can be dispatched immediately. At this time, the event monitoring function of the target display item starts to execute, monitors the simulation event and responds to the simulation event, so that the operation of the remote display item is realized.

Step 104: responding to the second operation event according to the target display item.

That is, after simulating a second operation event for the target presentation item according to the first operation event, the second operation event may be dispatched, so that the event monitoring function of the target presentation item monitors the event, and then responds to the second operation event, so that the remote operation on the target presentation item may be implemented.

As one example, if the floating selector is in the text selection mode, the display area of the floating selector displays thumbnail information for text snippets in multiple levels. In this case, if a first operation event of the thumbnail information of the reference text segment in the thumbnail information of the text segments of the plurality of hierarchies is detected, a second operation event of the reference text segment is simulated according to the first operation event, and a response is made to the second operation event according to the reference text segment. The reference text fragment is any one of the text fragments of the plurality of levels.

Next, a detailed description will be given of a process of implementing one-handed operation of a text in a display interface by the floating selector in a case where the floating selector is in a text selection mode.

Fig. 4 is a flowchart of another one-handed operation method provided in an embodiment of the present application, where the method is applied to a terminal, where the terminal may be a mobile phone, a tablet computer, or a computer, as shown in fig. 4, and the method includes the following steps:

step 401: and displaying a floating selector on the upper layer of the display interface, wherein the floating selector is in a text selection mode, and the text selection mode is used for selecting text from the display interface.

The text may be a text directly displayed in the display interface, or may also be a text in a picture or a text in a table displayed in the display interface, which is not limited in the embodiment of the present application.

In the embodiment of the application, if a user wants to quickly select a text, even a character in a picture, the user can select a text selection mode of the floating selector, and at this time, only the text content will display a focus in a display item crossed by a steering axis corresponding to the floating selector, that is, only the text can be selected.

Step 402: and displaying a text selection list in a display area of the floating selector, wherein the text selection list comprises a plurality of levels of thumbnail information of text segments, and the text segments of the plurality of levels are text segments in the text displayed by the display interface.

It should be noted that the interaction mode of the text selection mode is similar to the element selection mode, but the content displayed in the display area of the floating selector is slightly changed, and the display area no longer displays only a selected interface element, but automatically generates a text selection list according to the characteristics of the text, so that the user can switch the text segment to be selected.

The thumbnail information of the text segments of the multiple levels is the substitute display items of the text segments of the multiple levels, and the text ranges of the text segments of the multiple levels are sequentially increased. The hierarchical structure of the text fragments of the multiple hierarchies is as follows: the text selection list includes abbreviated information of words, participles, phrases, sentences, paragraphs, chapters and full texts in the display interface. The thumbnail information of the text segment may be a keyword or a beginning and ending character string of the text segment.

As an example, if the number of characters of the text segment is small, the thumbnail information of the text segment may be the text segment itself; if the number of characters of the text segment is large, the thumbnail information of the text segment can be a keyword or a head-tail character string of the text segment.

For example, for any one of the text segments in the multiple hierarchies, if the number of characters in the text segment is less than or equal to the number threshold, the thumbnail information of the text segment includes the text segment; if the number of characters in the text segment is larger than the number threshold, the abbreviated information of the text segment comprises a starting character string and an ending character string of the text segment.

The starting character string and the ending character string comprise M characters, and M is a positive integer. For example, if the number of characters in a text segment is greater than a number threshold, the thumbnail information of the text segment may include the first two characters and the last two characters of the text segment.

As one example, between the start string and the end string, an ellipsis may be used.

As one example, a selection focus corresponding to the floating selector is displayed in the current display interface, and the plurality of hierarchical levels of text segments include a target text segment at a location of the selection focus. The other levels of text fragments are generated based on the target text fragment, that is, the other levels of text fragments are lower levels of text fragments included in the target text fragment or are higher levels of text fragments containing the target text fragment.

Referring to fig. 5, if the target text segment at the position of the selection focus is the segmentation word "fund", the text selection list displayed in the display area of the floating selector may sequentially include: the word "fund" includes the word "fund", the word "fund" the phrase "fund return", the abbreviation "paired … return" of the sentence the word "fund" is in, and the abbreviation "if … return" of the paragraph the word "fund" is in.

After the text selection list is displayed in the display area, a user can freely select the thumbnail information of any text segment from the text selection list and operate the thumbnail information of the selected text segment, so that the remote operation of the same text segment in the display interface is realized. Therefore, remote selection and operation of the displayed text in the current display interface can be realized, the selection mode is simple and convenient, and any text fragment can be conveniently and quickly selected.

As shown in fig. 5, if "fund turn" is selected from the text selection list in the display area, the operation of selecting "fund turn" in the display interface can be realized, and the selected "fund turn" is highlighted.

It should be noted that, in order to enable the user to conveniently select the text, the structure of the text displayed on the current display interface may be analyzed in advance, that is, the displayed text is identified and analyzed into structured data.

As an example, in order for a user to select text in one piece, a full-text parse tree may be created that may be represented in the form of a list of text structures that is a nested structure.

As an example, before displaying the text selection list, for the text displayed on the current display interface, a text structure list of the text displayed on the display interface needs to be determined. The text structure list comprises a plurality of levels of text fragment lists, and each level of text fragment list comprises the thumbnail information of at least one text fragment positioned in each level.

For example, the text structure list includes at least one of a chapter list, a paragraph list, a sentence list, a phrase list, a participle list, and a word list. The chapter list comprises the thumbnail information of all chapters of a text displayed by the display interface, the paragraph list comprises the thumbnail information of all key paragraphs in any chapter, the sentence list comprises the thumbnail information of all key sentences in any paragraph, the phrase list comprises the thumbnail information of all key phrases in any sentence, the participle list comprises the thumbnail information of all key participles in any phrase, and the word list comprises the thumbnail information of all key words in any participle.

In addition, the text structure list may further include a picture list including thumbnail information of text identified from the picture and a table list including thumbnail information of text identified from the table.

It should be noted that the text structure list may be a nested structure, which may be as shown in fig. 6, a full text is nested with a chapter list, each chapter is nested with a paragraph list, each paragraph is nested with a sentence list, and may also be nested with a picture in a paragraph and a word in a table, and each sentence is nested with a phrase and a word.

When the text selection list is displayed in the display area of the floating selector, if a switching instruction of the thumbnail information of the reference text segment in the thumbnail information of the text segments of the multiple hierarchies in the text selection list is detected, the thumbnail information of the reference text segment can be switched to the thumbnail information of other text segments in the text list of the hierarchy where the reference text segment is located based on the text structure list, and the reference text segment is any one of the text segments of the multiple hierarchies. Therefore, any text segment can be switched quickly, and the text selection efficiency is further improved.

For example, referring to fig. 5, if a switching instruction for the phrase "fund return" in the current text selection list is detected, the phrase "fund return" may be switched to other phrases in the phrase list corresponding to the current paragraph, for example, the phrase "fund return" is switched to the previous phrase "self-contact".

For another example, if a switching instruction of "follow pair … turn" in the current text selection list is detected, the sentence "follow pair … turn" may be switched to other phrases in the sentence list corresponding to the current paragraph, for example, "follow pair … turn" may be switched to the previous sentence "please refer to the … number".

The switching instruction of the thumbnail information of the reference text segment may be triggered by a user through a switching operation, where the switching operation may be a sliding operation or a clicking operation of the thumbnail information of the reference text segment, and the switching operation is not limited in this embodiment of the application. For example, if the thumbnail information of the reference text segment slides to the left, the previous text segment of the reference text segment may be switched to, and if the thumbnail information of the reference text segment slides to the right, the next text segment of the reference text segment may be switched to.

For example, referring to fig. 5, if "fund return" is slid to the left, it may be switched to the previous phrase in the current paragraph, and if "fund return" is slid to the right, it may be switched to the next phrase in the current paragraph.

As one example, when a user first selects text using the floating selector, the word pointed by the selection focus is selected by default, and the participle list is selected in the display area of the floating selector, and if a change is desired, the list in the display area can be slid to switch. For example, referring to FIG. 5, sliding down the selectable sentences and updating the list into a list of selectable sentences; sliding the selectable paragraph down continues to generate a selectable paragraph column.

As one example, the operation of determining a list of word segments in the text structure list may include: performing word segmentation processing on a text displayed on a display interface to obtain a plurality of words; determining at least one keyword from the plurality of segmented words; based on the at least one keyword, the list of participles is determined.

Word Segmentation is also called Text Segmentation, which is the most basic technology in NLP (Natural Language Processing), and for languages such as chinese and japanese, it is not necessary to separate words by using spaces, and it is necessary to recognize continuous character sequences as independent words to facilitate users to accurately and quickly select words, which is also a precondition of syntactic analysis. Although English naturally separates words by spaces, independent words cannot be resolved by spaces completely, and punctuation marks are also considered. Therefore, the word segmentation process is required to be performed on the text.

Wherein the operation of determining at least one keyword from the plurality of segmented words comprises: performing part-of-speech tagging on the multiple participles to obtain the part-of-speech of the multiple participles; selecting a participle meeting the part-of-speech requirement from the participles based on the part-of-speech of the participles; and extracting the keywords from the selected participles to obtain the at least one keyword. The participles meeting the part-of-speech requirement can be preset, such as nouns and verbs.

As one example, word segmentation and part-of-speech tagging may be performed using DAG (Directed acyclic graph) and HMM (Hidden Markov Model) models.

For example, an offline statistical dictionary is first constructed, where the offline statistical dictionary includes a plurality of words and the word frequency and the word property of each word, and then a prefix dictionary is constructed based on the statistical dictionary. Then, each sentence in the displayed text is scanned based on the prefix dictionary to form a directed acyclic graph formed by all possible word-forming words based on the prefixes, and all the possible word-forming words are labeled with parts of speech in the process. For the unknown part-of-speech words, part-of-speech tagging can be performed on the unknown part-of-speech words through an HMM model.

The HMM model finds a maximum probability path by adopting dynamic planning, finds out a maximum text segmentation combination based on word frequency to obtain an optimal state sequence, and then outputs the results of word segmentation and part of speech tagging according to the state sequence.

When extracting the keywords from the selected segmented words, the method may be performed by using supervised learning, or may be performed by using unsupervised learning.

As an example, the keyword extraction may be performed by combining TF-IDF (Term Frequency-Inverse Document Frequency, a commonly used weighting technique for information retrieval and data mining) and TextRank algorithm, that is, extracting a first keyword set from the selected participles through TF-IDF, extracting a second keyword set from the selected participles through TextRank algorithm, and using an intersection part of the first keyword set and the second keyword set as a final extracted keyword set.

In addition, if the intersection of the first keyword set and the second keyword set is empty, the first keyword set is used as the final extracted keyword set. The TF-IDF does not consider semantics, when the threshold is set in a certain range, the result of the TextRank algorithm is only a subset of the TF-IDF result, the convenience of one-hand operation is considered, the selection of the keywords is as comprehensive as possible, and the condition that the keywords need to be clicked independently is avoided, so that the first keyword set can be used as the finally extracted keyword set.

The TF-IDF algorithm is to calculate the TF-IDF value of each selected participle respectively, arrange the participles in a descending order according to the TF-IDF value of each participle, and take the sequenced participles with the appointed number as possible keywords. Where the TF-IDF value is the word frequency multiplied by the inverse of the number of times a word appears in the document.

The TextRank algorithm refers to that grammar units in a text are regarded as nodes in a graph, if two grammar units have a certain grammar relationship (for example, co-occurrence), the two grammar units have one edge in the graph and are connected with each other, different nodes have different weights finally through a certain number of iterations, and grammar units with high weights can be used as keywords.

As one example, the operation of determining a list of sentences in the text structure list may include: for a plurality of sentences included in the text displayed on the display interface, carrying out abstract extraction on the plurality of sentences to obtain the abstract of the plurality of sentences; deleting redundant sentences from the sentences based on the abstracts of the sentences to obtain at least one sentence; determining thumbnail information for each of the at least one sentence; the list of sentences is determined based on the abbreviated information of the at least one sentence.

Wherein, the abstract of the sentence can be the central word of the sentence, etc.

As an example, the headword of each sentence can be extracted by using a combination of a PCFG (Probabilistic Context Free Grammar) algorithm and a TextRank algorithm.

For example, a syntactic structure tree may be formed based on the context-free dependency parsing using the calculation result of the PCFG algorithm as the parsing basis, and then the first importance of each participle in each sentence may be determined based on the syntactic structure tree. And determining a second importance degree of each participle of each sentence by adopting a TextRank algorithm. And then carrying out weighted summation on the first importance degree and the second importance degree of each participle in each sentence according to the weight to obtain the third importance degree of each participle in each sentence, and taking the participle with the highest third importance degree as the central word of the sentence. Wherein the second degree of importance is the TextRank value of the participle.

It should be noted that for the PCFG algorithm, it is important to specify a word if it appears after many words. For the TextRank algorithm, if a word with a high TextRank value is followed by a word, the TextRank value of the word is correspondingly increased, and the importance degree is correspondingly increased.

As an example, when a redundant sentence is deleted from the sentences based on the digests of the sentences, the digests can be regarded as an optimization problem with constraints, and solved based on the ILP (Integer Linear Programming), and the redundant sentence is removed to form a sentence digest set.

Wherein the operation of determining the sentence list based on the thumbnail information of the at least one sentence comprises: the list of sentences is determined based on the summary and the abbreviated information of the at least one sentence. For example, a summary and thumbnail information of at least one sentence are formed into a sentence list.

As one example, the operation of determining a list of paragraphs in a text structure list may include: for at least one paragraph included in the text displayed by the display interface, determining the thumbnail information of each paragraph; the paragraph list is determined based on the thumbnail information of the at least one paragraph.

In addition, before determining the paragraph list based on the thumbnail information of the at least one paragraph, for a reference paragraph in the at least one paragraph, keywords of each sentence in at least one sentence included in the reference paragraph may also be determined; determining a central word of each sentence from the keywords of each sentence; determining at least one headword from the headword of the at least one sentence as a paragraph title of the reference paragraph based on the keyword weight of the headword of each sentence; the paragraph list is determined based on the paragraph titles and the thumbnail information of the at least one paragraph. Wherein the reference paragraph is any one of the at least one paragraph.

As an example, the central word of each sentence can be determined from the keywords of each sentence by using a combination of the PCFG algorithm and the TextRank algorithm.

As an example, the process of performing structure analysis on the text may obtain a text structure list through the processing flow shown in fig. 7, as shown in fig. 7.

It should be noted that the text structure analysis of the present application may include two parts, namely, offline preprocessing and online real-time processing, for a text known to the system, preprocessing may be performed at the server in advance, and for a newly appearing text, real-time analysis may be performed after the text is displayed and when the text selection mode of the floating selector is turned on.

It should be noted that, for the pictures in the display interface, text recognition may be performed on the pictures by using a CRNN (convolutional neural network) model to obtain a text recognition result, and then the recognized text is added to the paragraph list of the current paragraph.

As an example, when text recognition is performed on a picture using a crnn (Convolutional Neural network) model, a CNN (Convolutional Neural network) may be used in a Convolutional layer, a feature sequence of the picture may be extracted through the Convolutional layer, a two-layer LSTM (Long Short-Term Memory ) may be used in a cyclic layer to predict a label distribution of the feature sequence, and then, a recognition result text may be finally formed in a transcription layer through processing such as de-duplication and integration.

It should be noted that if the selected text range is to be fine-tuned, a fine-tuning tool in the display area may be used, that is, icons on the left and right sides of the selected item are pressed and the icons on either side are slid in any direction, so that the text selection range can be adjusted. The self-contained selection and adjustment tool of the system can be used, and the self-contained tool of the system can be operated only by simulating a corresponding event.

In addition, after fine tuning, if the selected text is not a complete word or phrase, nor a complete sentence, the currently selected text can be inserted into the text structure list as a new item.

Step 403: if a first operation event of the thumbnail information of the reference text fragment in the thumbnail information of the text fragments of the multiple hierarchies is detected, simulating a second operation event aiming at the reference text fragment according to the first operation event, wherein the reference text fragment is any one of the text fragments of the multiple hierarchies.

Under the condition that a selection focus corresponding to the floating selector is further displayed on the display interface, the text segments of the multiple hierarchies comprise a reference segmentation and at least one text segment covering the reference segmentation, and the reference segmentation is a segmentation corresponding to the position of the selection focus.

Step 404: and responding to the second operation event according to the reference text segment.

The text operation may be a selection operation, a copy operation, a cut operation, or the like, and the embodiment of the present application is not limited thereto.

The target indicated by the selection focus is generally a single character or a continuous character, the leftmost side of the first character is the starting point, and the rightmost side of the last character is understood to be the ending point. The coordinates of the longitudinally centered point of the left edge of the starting point are used as the remote coordinates of the starting point of the fine tuning tool, and correspondingly, the coordinates of the longitudinally centered point of the right edge of the end point are used as the remote coordinates of the end point of the fine tuning tool.

When the fine tuning tool in the display area is used, the adjustment coordinate of the user can be obtained when the adjustment event of the user is obtained, and the movement event can be continuously triggered when the finger of the user moves. In the process, the key points can continuously acquire new coordinates, calculate relative positions and create new simulation events so as to dispatch the new events above the starting point or the ending point of the actual text to generate relative movement.

It should be noted that from the perspective of the provider of the application, if some text is not intended to be selected by the user, it may also be set to disallow selection.
