Description
Technical Field
The application relates to the technical field of education and internet, in particular to an internet-based education information search system.
Background
At present, electronic products are more and more popular, intelligent terminal products are widely used, methods for shooting a difficult problem and seeking network answering by using camera functions of mobile phones, tablet computers and the like are widely used, however, in the existing methods, after the difficult problem is shot, a user needs to manually pull a clip frame to select a target area, much time and energy are often needed for the operation, the dragging and selecting of the question is not easy to operate and is not accurate enough, the manual dragging often causes the problem of more frames or less frames, the answer seeking process is difficult, the answer seeking process is slow, and even the situation of wrong answering is caused, nowadays, the student academic industry is heavy, and the difficulty of seeking the answer by students is reduced as much as possible.
At present, many electronic education products on the market can realize the function of shooting and searching questions, and corresponding paraphrases are searched by shooting words or phrases, or corresponding answers are searched by shooting questions. The realization of the existing photographing and question searching function mostly needs to be realized through the following steps: starting a camera, photographing, intercepting a search object in an image, converting the search object into text through an OCR technology, searching by a server and matching a search result, and feeding the search result back to the electronic terminal by the server. However, when a user takes a question, the image often has many questions, and in the prior art, the question that the user wants is intercepted through a fixed question intercepting frame, so that the operation is complicated and errors are easy to occur.
In view of the above problems, the document CN106326415A provides a method for acquiring a shooting object and a test question text block by cursor positioning, which is simple in operation, and can effectively improve the precision of test question capturing, and also omits the step of confirming the test question, optimizes the whole process of shooting and searching the test question, and enhances the user experience.
The document CN106295514A, by applying APP of the scanned textbook image recognition technology, does not need to search the textbook according to the subject, version, and grade of the book when performing the synchronous learning tutoring or searching for a certain page of content of the textbook, and then searches for the required content page by page, and does not need to waste the whole flow and download the whole textbook, and only needs to scan lightly to accurately locate the required textbook page for the synchronous operation tutoring.
Firstly, although the above methods improve the picture taking, the above methods do not integrate the resources on the server side, so that the search results of the resources are inevitably difficult to satisfy the diversified topic requirements; secondly, the method only improves the title acquisition process, but does not optimize the search part in the title searching process, which may cause the problems of low searching efficiency and inaccurate searching result; finally, the method for processing the shot image and acquiring the title needs to be realized by means of the position change of a manual trigger cursor of the user, so that the method for manually acquiring the title is low in efficiency and low in intelligent degree, and cannot meet the automatic requirement of the user easily.

Detailed Description
The embodiments of the present invention are further described below with reference to the drawings.
The first embodiment is as follows:
as shown in fig. 1, the present invention provides an internet-based educational information search system, which includes a mobile terminal, an internet gateway, an internet-side database, and a search engine, wherein the internet gateway establishes communication connections with the mobile terminal, the internet-side database, and the search engine, the internet-side database and the search engine are respectively provided in plurality, and the mobile terminal is further provided with a plurality of local databases; the educational information search system performs the following operations by a processor of the mobile terminal:
s1, setting a database for searching questions, a search engine and a priority relation thereof by a user through a mobile terminal, wherein the database comprises a local database and an Internet end database; it should be noted that the setting is performed before the topic search is performed, for example, the database may be a wrong-question database stored in the process of performing the topic practice in other application programs of the mobile terminal of the user or a practice question database directly calling other answer practice application programs, at this time, the mobile terminal needs to be changed to obtain corresponding database reading rights to obtain the topics and answers thereof in the multiple different databases. In addition, the search engines are implemented based on the internet, and for example, the search engines are one or more of hundredths, google, 360 and the like; once the priority relation between the database and the search engine is set, the corresponding database and the corresponding search engine can be directly called to search in the searching process, and characters do not need to be manually analyzed from the image and then copied to a search window to execute searching operation; the invention directly and automatically extracts the keywords from the analyzed character information and executes the search, thereby improving the search efficiency and avoiding the complicated steps of manual operation of the user.
S2, the mobile terminal receives the title search command of the user, obtains the category of the title search command, and if the title search command is an image title identification search command, the step S3 is executed; if the title searching instruction is a text title identification searching instruction, acquiring a text of a selected area in a current display interface of the mobile terminal selected by a user, and taking the text of the selected area as an object of title identification; if the area is not selected by the title searching instruction, all texts in a webpage where a current display interface of the mobile terminal is located are used as objects for title identification; automatically judging the type of the titles and the number of the titles based on the title identification objects of the texts, and marking the type information of the titles to the corresponding titles; proceeding to step S4; it should be noted that, in the step S2, the categories of the topic search instruction are distinguished, that is, the text category and the image category, so that the efficiency and the speed of identifying the topic are improved; in addition, the image types are not limited to the currently stored pictures of the mobile terminal, and may also be image information acquired by a camera of the mobile terminal in real time, which is not limited herein. In addition, aiming at the problem identification without text selection operation of the user, all texts for identifying the webpage where the current display interface is located are adopted as the object of the problem identification, so that the flexibility of text identification can be improved, and the diversified and personalized requirements of the user can be met.
S3, automatically judging the type of the topics and the number of the topics based on the image, and marking the type information of the topics to the corresponding topics; the number of the titles and the types of the titles are one or more; it should be noted that the content of the image generally includes a region where the title is located, a region where the paper including the title is located, and an unrelated region outside the paper; in addition, besides acquiring image information of a topic by a camera, the image information may also be acquired by screen capture of a mobile terminal, or image information received from a server or the like, that is, the source of the image information may be various, which is not limited herein. Because the titles in the image information are usually in the middle or in a specific rectangular area, different titles can be distinguished by special marks such as lines, titles, serial numbers and the like; therefore, the number of the topics can be judged based on the position of the region and the special marks such as the row, the line, the title, the serial number and the like, that is, each judged region which is relatively independent is used as one topic; preferably, the type of the topic is determined according to the information such as the row and column where the topic is located, the upper and lower positions of the topic, the row and column indentation relationship, and the serial number obtained by the analysis, for example, the keyword "determination" in the primary topic, and if the serial numbers 1/2 appear in a plurality of secondary topics identified by the row and column indentation relationship at the lower part of the primary topic, the topic type after the serial number 1/2 is identified as the determination topic, and the serial number 1/2 indicates that there are 2 choice topics. In addition, one picture may include not only a plurality of titles of the same type but also titles of different types, and the determination method is similar to the above method, which is not described herein again.
S4, searching the titles in the database with the first priority and the search engine with the first priority respectively based on the type information of the titles, comparing a search result A1 in the database with a search result B1 in the search engine, and feeding back the search result A1 or B1 to the user through the mobile terminal if the database search result A1 is consistent with the search engine search result B1; if the database search result A1 and the search engine search result B1 do not match, proceed to step S5; it should be noted that, continuing with the above embodiment, if the search result a1 in the database of the above judgment topic 1 is "pair" and the search result B1 in the search engine is "pair", the "pair" of the search result is fed back to the user through the mobile terminal; in addition, for blank filling questions or question answering questions, since the answer of the search result may not be unique, a fault tolerance mechanism is established for such questions to avoid a judgment error, for example, a keyword may be extracted for the user to show the search result. In addition, a search mechanism different from that of a search engine is adopted for searching the database, namely, the database is divided according to the topic types, each topic type corresponds to one sub-database, and when the searched topic type is judged to be a judgment question, the search operation is only carried out in the sub-database corresponding to the judgment question, so that the search efficiency can be improved; and for the search engine, because the search capability is more intelligent, the search can be more flexible at the moment, and a search mode combining the topic type and the topic can be adopted to search in the search engine, so that the search efficiency is improved, and the interference to the search result caused by data redundancy is avoided.
S5, searching the titles in a database with a second priority and a search engine with a second priority respectively based on the type information of the titles to obtain a search result A2 in the database and a search result B2 in the search engine, comparing the search results A1, B1, A2 and B2, and if only one search result with the largest occurrence number exists, providing the search result with the largest occurrence number to the user; and if the search results with the largest number of occurrences are multiple, feeding back error information to the user, and providing the multiple search results with the largest number of occurrences to the user. It should be noted that, continuing with the above embodiment, if the search result a1 in the database of the above determination question 1 is "pair", the search result B1 in the search engine is "error", and since the search results of the first priority are inconsistent, the correctness of the search result cannot be determined at this time, the questions are searched in the database of the second priority and the search engine of the second priority, and then 4 search results are compared, and if only one search result with the largest occurrence number is found, for example, "error", the search result with the largest occurrence number is provided to the user as "error"; if the search results with the largest number of occurrences are multiple, for example, two of 'error' and 'pair', the search results are judged to be contradictory at the moment, error information is fed back to the user, and the multiple search results with the largest number of occurrences are provided for the user.
As a preferred embodiment, the setting, by the user, of the database and the search engine for title search and the priority relationship thereof through the mobile terminal specifically includes:
recommending and setting a plurality of databases and priority relations thereof, a plurality of search engines and priority relations thereof for the user through a mobile terminal according to the historical setting information of the user or the ranking information of the server side; and after receiving the command of searching the titles, the database and the search engine with the same priority simultaneously trigger the search operation. It should be noted that, for the priority setting mode of the database, the setting order under the initialization condition or the default condition is displayed for the user during the first setting, and the user can adjust the setting order on the basis; defaulting the last setting sequence for the user during subsequent setting, and further adjusting the sequence by the user on the basis; the search engine may set the priority by using a method similar to the above-mentioned database, which is not described herein. Thereby, the setting efficiency of the user can be improved. In addition, the efficiency of searching can be improved by triggering the searching operation for the database and the search engine with the same priority.
As a preferred embodiment, the mobile terminal obtains the clear image of the title, and automatically determines the type of the title and the number of the titles based on the clear image, and specifically includes:
the mobile terminal acquires the clear image of the title, divides the image according to regions, only one title is included in each divided region, and deletes the image of the divided region without the title; automatically judging the type of the topic based on the image of the segmentation region of the topic, wherein the type of the topic comprises any one or more of the following items: filling in blank questions, judging questions, selecting questions and asking and answering questions; and the number of the images of the segmentation areas is used as the number of the titles. It should be noted that, because all the titles in the image information are usually in the middle or in a specific rectangular area, different titles can be distinguished by special marks such as rows, columns, titles, serial numbers, etc.; therefore, the number of the topics can be judged based on the position of the region and the special marks such as the row, the line, the title, the serial number and the like, that is, each judged region which is relatively independent is used as one topic; preferably, the type of the topic is determined according to the information such as the row and column where the topic is located, the upper and lower positions of the topic, the row and column indentation relationship, and the serial number obtained by the analysis, for example, the keyword "determination" in the primary topic, and if the serial numbers 1/2 appear in a plurality of secondary topics identified by the row and column indentation relationship at the lower part of the primary topic, the topic type after the serial number 1/2 is identified as the determination topic, and the serial number 1/2 indicates that there are 2 choice topics. In addition, one picture may include not only a plurality of titles of the same type but also titles of different types, and the determination method is similar to the above method, which is not described herein again.
As a preferred embodiment, one or more of the titles and the types of the titles thereof specifically include:
when only one question exists, automatically judging the type of the question based on the image of the segmentation region of the question, and converting the image of the segmentation region of the question into character information; searching in a sub-database of the topic type of the database corresponding to the priority according to the topic type; and converting the type of the title into text information, and searching in a search port of the search engine with corresponding priority based on the text information of the title and the text information of the type of the title. It should be noted that, when a search is performed on a topic in a search engine, a keyword extraction operation needs to be performed on the topic to improve the search efficiency.
As a preferred embodiment, one or more of the titles and the types of the titles thereof specifically include:
when the number of the titles is only a plurality, automatically judging the type of each title based on the image of the segmentation area of the title, and converting the image of the segmentation area of each title into character information; searching each topic in a sub-database of the topic type of the database corresponding to the priority according to the topic type in a pipeline mode; converting the type of each topic into text information, and searching each topic in a searching port of the searching engine with corresponding priority based on the text information of the topic and the text information of the type of the topic in a pipeline mode. It should be noted that, when there are a plurality of topics, the plurality of topics are sequentially and automatically searched, the search result may be automatically covered in the region where the topic corresponding to the acquired image is located, and the search result may also be displayed in a dialog box, which is not limited herein. The title search mode of the pipeline is exemplarily as follows: for the titles M1-M3, the database and the search engine with the first priority search the title M1 first, if the search results are consistent, the database and the search engine with the first priority directly exit the search pipeline, if the search results are inconsistent, the database and the search engine with the second priority search the title M1 first, at this time, the database and the search engine with the first priority search the title M2 first, and so on.
In addition, when there are only one or a plurality of questions, the question type may be determined by the question internal information determination, for example, by a sentence break of the analyzed question information, and as an example, if there is an underline in the question sentence, it is determined as a blank question, and if there is a bracket at the end of the question sentence, it is determined that the question is a determination question.
As a preferred embodiment, if the title search instruction is a text title identification search instruction, acquiring a text of a selected area in a current display interface of the mobile terminal selected by a user, and taking the text of the selected area as an object of title identification specifically includes:
judging whether a user selects a text in the current display interface of the mobile terminal, if so, displaying a title search option at the edge of the selected text after the user completes the selected operation, taking the search option as a text title identification search instruction after detecting that the user selects the search option, automatically acquiring the text of a selected area in the current display interface of the mobile terminal selected by the user, and taking the text of the selected area as an object of title identification. It should be noted that the title search option displayed at the selected text edge after the selected operation may be a search option popped up directly after the selected operation by the user, or a search option displayed after the right key operation after the selected operation by the user. Because the presentation mode of the title is not limited to the text, but may also include the content of pictures, characters and the like in the middle of the text, the text of the selected area also includes the information of the pictures, characters and the like in the text of the selected area; in this case, it is necessary to identify the text of the selected region and the contents such as pictures and characters in the middle of the text as subjects.
As a preferred embodiment, if the area is not selected by the title search instruction, taking all texts in a webpage where a current display interface of the mobile terminal is located as objects of title identification specifically includes:
judging whether a user executes long press operation in a current display interface of the mobile terminal, if so, displaying a title search option on the current display interface of the mobile terminal after the user finishes the long press operation, automatically acquiring a source file of a webpage where the current display interface of the mobile terminal is located after detecting that the user selects the search option, reading text information in the source file < body >, and taking the text information in the source file < body > as an object for title identification. It should be noted that after the user completes the long-press operation, a title search option is displayed on a current display interface of the mobile terminal, which may be a search option displayed after the user performs the long-press operation or after the user performs the right-key operation; at the moment, if the user selects the search option, because the text selection operation is not carried out, all titles in the current page document are defaulted as search objects; in order to quickly acquire title information in a page document, a source file of a current page, namely an xml file, can be automatically acquired, and text content is usually stored in a < body > </body > tag according to the editing habit of the xml file, so that the text information in the < body > </body > tag is directly acquired by the method, and the identification speed of interface display content is improved. Furthermore, similar to the above embodiment, since the presentation manner of the title is not limited to only text, but may also include the contents of pictures, characters, etc. in the middle of the text, the text in the < body > </body > tag also includes the information of pictures, characters, etc. in the text of the selected area; in this case, it is necessary to identify the text in the < body > </body > tag and the contents of the picture, character, and the like in the middle of the text as objects for title recognition.
