With continued reference to FIG. 2, a flow 200 of one embodiment of an information output method according to the present application is shown, comprising the steps of:
step 201, in response to receiving an image acquisition request of a user, acquiring an image including a question to be solved.
In this embodiment, after receiving an image acquisition request from a user, an executing subject (for example, the terminal device in fig. 1) may acquire an image including a question to be answered through a shooting device configured by the executing subject, or may acquire an image including a question to be answered and stored locally by the executing subject.
In this embodiment, the operation of initiating the image acquisition request by the user may be submitted in a human-computer interaction manner in the prior art or in a future developed technology. These human-computer interaction means include, but are not limited to: shaking the terminal, clicking on a virtual button (e.g., a virtual button displayed on a display screen), clicking on a physical button, gesture recognition, voice recognition, or other human-machine interaction means developed in the future. Taking gesture recognition as an example, the camera of the execution main body acquires gesture information of the user, and compares a predefined operation gesture corresponding to an operation of initiating the image acquisition request. And submitting the operation of the image acquisition request if the user gesture is identified as an operation gesture corresponding to the operation of initiating the image acquisition request. Correspondingly, the execution subject of the embodiment may provide for receiving and identifying the image acquisition request submitted based on the submission method described above.
In this embodiment, the questions to be solved may be various disciplines and types of questions in education and learning, including but not limited to calculation questions in the mathematics discipline, blank filling questions in the Chinese discipline, and shape filling questions in the English discipline. The image of the question to be solved may be an image of an examination paper, an image of an exercise book.
In some optional implementation manners of this embodiment, the image acquisition request of the user may be used to instruct to continuously shoot a preset number of images including the question to be answered within a preset time period; the execution main body continuously shoots a preset number of images including the questions to be answered within a preset time period according to the image acquisition request; and selecting the image with the highest definition from the preset number of images including the questions to be solved as the image for performing text extraction next.
Step 202, extracting text content in the image, and performing structured classification on the text content.
In this embodiment, the text content in the image may be extracted by an OCR (Optical Character Recognition) method. In some optional implementation manners, the execution subject firstly performs image processing on the image to be solved, and performs text recognition based on the image after the image processing to extract text content in the image. The specific image processing process is as follows: firstly, carrying out gray level processing on an image comprising a question to be answered, and generating a gray level image through a color image; then, generating a black-white image of the image according to the gray scale image of the image, wherein the black-white image only has black and white colors; then, eliminating noise points in the black and white images, because the quality of the image to be recognized is limited by the input equipment, the environment and the printing quality of the document, before the characters in the image are recognized, the image to be recognized needs to be subjected to denoising processing according to the characteristics of the noise, and the recognition processing accuracy is improved. Then, performing tilt correction on the noise-reduced image to enable text content in the image to be displayed horizontally; and finally, horizontally cutting and vertically cutting the corrected image to obtain a single character based on the text content in the image.
The specific text recognition process is as follows: firstly, generating template characters of characters in various fonts based on all characters used in life and study of people; normalizing the character to be recognized based on the text content obtained after image processing, and recording meta (element) information of the character; finally, according to the normalized character to be recognized and the corresponding meta information, matching the template character with the character to be recognized to recognize the character to be recognized, wherein the specific matching method comprises but is not limited to: character pixel matching, projection block matching, Sudoku matching, center matching, aspect ratio matching and the like.
In this embodiment, after the text information in the subject recognition image is executed, the text information needs to be classified structurally. And the structured classification is used for classifying the recognized text information based on the keywords of the questions to be solved, and the text information after structured classification comprises the question stems of the questions to be solved. For example, if the execution subject recognizes a keyword of "happy anti-sense word" from the text information, the execution subject performs structured classification based on the keyword to obtain a stem indicating to fill in the space with the anti-sense word. In some optional implementation manners, the structured and classified text content further includes a text to be solved corresponding to the question stem, and the text to be solved is used for representing text information of the text to be answered, which needs to be output according to the question stem. For example, the structured and classified text content may include stem information of "filling out similar meaning words" and a text to be solved under the stem information, where the text to be solved is various words in which the similar meaning words need to be filled out.
The execution subject for executing the present step may be a mobile terminal or a server. When the execution main body is the mobile terminal, after the mobile terminal acquires the image comprising the questions to be solved, extracting and structurally classifying the text content of the image; when the execution subject is the server, the server extracts and structurally classifies the text content of the image according to the image which is acquired by the mobile terminal and comprises the question to be answered.
And step 203, outputting an answer text of the question to be solved through a pre-trained answer model based on the text content after structured classification.
In this embodiment, the pre-trained answer model may obtain, through a machine learning method, an answer text of the to-be-solved question corresponding to the text content according to the input text content based on semantic understanding. The answer model carries out directional training in different categories through questions to be solved based on different subjects and different question types, so that the model can identify the questions to be solved of each question type to obtain corresponding answer texts.
In some alternative implementations, the answer model is trained by: acquiring a training sample set corresponding to the question type of a question to be answered, wherein the training sample set comprises a text set to be answered and an answer text set, and answer texts in the answer text set correspond to texts to be answered in the text set to be answered one by one; and taking the text to be answered in the text set to be answered as the input of the initial answer model, taking the answer text corresponding to the text to be answered in the text set to be answered in the answer text set as the target output, and training the initial answer model to obtain the answer model. Specifically, the executing body may use models such as a convolutional neural network, a deep learning Model, a Naive Bayesian Model (NBM), or a Support Vector Machine (SVM), take the text to be solved in the text set to be solved as the input of the Model, take the answer text corresponding to the text to be solved in the text set to be solved in the answer text set as the output of the Model, and train to obtain the answer Model.
The execution main body can acquire answer texts of the questions to be answered through a pre-trained answer model according to the text contents after structured classification; in other optional embodiments, the execution subject may also obtain an answer text of the to-be-answered question by combining the preset database and the pre-trained answer model, where the combination may be that, first, the answer text is obtained through the preset question library, and under the condition that the preset database cannot obtain the answer text, the answer is obtained through the pre-trained answer model; or the answer text of the question to be solved can be simultaneously obtained through a preset database and a pre-trained answer model. In some optional implementation manners, the answer text of the question to be solved is obtained simultaneously by the following method: firstly, according to the question stem, obtaining an answer text corresponding to a text to be answered through a preset database; and according to the question stem, obtaining an answer text corresponding to the text to be answered through a pre-trained answer model. And then, setting the answer text obtained by the pre-trained answer model and the text with the highest matching degree with the text to be answered in the answer texts obtained by the preset database as the final answer text of the question to be answered.
The matching degree of the answer text obtained by the answer model and the text to be answered is determined by the confidence coefficient which is output by the answer model and corresponds to the answer text; the matching degree of the answer text obtained through the preset database is determined by the matching degree between the questions in the question bank and the questions to be solved, and the matching degree between the questions in the question bank and the questions to be solved comprises the matching degree of the question stem between the questions in the question bank and the questions to be solved and the matching degree of the text to be solved.
The matching degree of the question stem and the matching degree of the text to be solved can be determined according to the number of matched keywords and the total number of the keywords. For example, the question stem of the question to be solved is "to perform space filling with an antisense word", the text to be solved includes 9 words such as "open heart", "weak small", and the like, wherein the keywords recognized according to the question stem are "space filling with an antisense word", the keywords recognized by the text to be solved are 9 words of the text to be solved, and thus, the total number of the keywords to be solved is 10. If 7 keywords of the topics searched in the preset database are the same as the keywords of the questions to be solved, it is determined that the matching degree of the answer text of the topics searched in the question database is 7/10, that is, the matching degree is 70%. In some alternative implementations, different weights may be set for the keywords of the question stem and the keywords of the text to be solved, so as to obtain a more accurate matching degree. The preset database is a database containing all disciplines, all types of questions and corresponding answers. In order to avoid the problem of inaccurate answer caused by incomplete database, the preset database needs to be updated in time, and the updating manner includes, but is not limited to, correction of wrong answers, supplement of data, and the like. In some optional embodiments, the update time may be preset, and the preset database may be updated in time in response to the update time being reached. The channels for acquiring the updated contents of the database include, but are not limited to, various academic databases, browsers, electronic books and the like.
The execution subject for executing the present step may be a mobile terminal or a server. When the preset database and the pre-trained answer model are arranged in the mobile terminal, the execution main body of the step is the mobile terminal provided with the preset database and the pre-trained answer model; when the preset database and the pre-trained answer model are arranged in the server, the execution main body of the step is the server provided with the preset database and the pre-trained answer model.
In the embodiment, the execution main body obtains the answer text of the to-be-solved question through the pre-trained answer model, so that the problem that the question analysis is inaccurate due to incomplete database and untimely database updating when the answer text is obtained through the preset database can be solved, and the accuracy of intelligent question solving is improved.
Fig. 3 schematically shows one application scenario of the information output method according to the present embodiment. The user 301 clicks a virtual button on the smartphone 302 and initiates an image acquisition request. The smartphone 302 receives an image acquisition request of the user 301, and captures a language test paper 304 being processed by the user 301 to obtain an image including a question to be solved in the language test paper. The smart phone 302 uploads the acquired image to the server 303, the server 303 processes the image transmitted by the smart phone 302, extracts text content in the image, and structurally classifies the text content; then, based on the structured and classified text content, the server 303 outputs an answer text of the question to be solved through a pre-trained answer model in the server.
