Description

  The present invention relates to a technique effective when applied to a learning system that displays a sentence for language learning.

  As a technique related to an apparatus for presenting a sentence structure to a user for learning sentences such as English, there is a technique for displaying a dependency in a sentence. For example, Japanese Patent Laid-Open No. 5-35781 (Patent Document 1) describes that a dependency analysis is performed based on a morphological analysis result of a character string and the dependency analysis result is displayed. As an example of the dependency analysis result, an example in which the dependency is indicated by an arrow is described in FIG. In addition, as shown in FIG. 14A, it may be possible to show the dependency of English sentences.

  The various servers described above include an OS (Operating System), a DBMS (DataBase Management System), and a Web server program that are expanded on a memory from a recording device such as an HDD (Hard Disk Drive) by a CPU (Central Processing Unit) (not shown). By executing middleware such as the above, and software running on the middleware, various functions described later relating to learning service provision are realized.

  The syntax analysis server 5 is a server device that executes syntax analysis and the like. The syntax analysis server 5 acquires a learning target sentence from the learning data generation server 3 and receives a syntax analysis request. The syntax analysis server 5 performs morphological analysis and syntax analysis on the acquired sentence to be learned, and transmits analysis information to the learning data generation server 3 as a result of the syntax analysis.

  Here, the analysis information is information based on the result of the syntax analysis of the sentence to be learned, and specifically indicates the word (morpheme) in the sentence and the dependency of the word in the sentence to be learned. Information (intercept information) and information indicating the part of speech of each word of the sentence to be learned are included. Note that morphological analysis and syntax analysis are performed by known methods. The information indicating the dependency includes information indicating the parent-child relationship of the dependency, information indicating the dependency hierarchy (for example, information indicating one of the parent, the immediate child, and the child immediately below). It is.

  The dictionary management server 6 is a server device that provides translations of words acquired from the learning data generation server 3. The dictionary management server 6 stores dictionary information (dictionary information indicating the meaning of each word) in advance. Examples of this dictionary include an English-English dictionary, an English-Japanese dictionary, a Japanese-English dictionary, and a collection of important words with English qualifications. The dictionary management server 6 receives the word and the part of speech of the word from the learning data generation server 3 and also receives a word translation request. When the dictionary management server 6 receives the word translation request, the dictionary management server 6 refers to the dictionary information, acquires a translation corresponding to the part of speech of the word, and transmits word semantic information indicating the translation to the learning data generation server 3.

  Here, the word meaning information is information indicating the meaning of each word of the sentence to be learned. In addition, the dictionary management server 6 also holds information defining important words in advance, and when there is a word corresponding to the important word among the words received from the learning data generation server 3 with reference to the information, Information indicating that it is an important word is also transmitted to the learning data generation server 3.

  The grammar server 7 is a server device that generates grammar information based on analysis information and provides the grammar information. Here, the grammatical information is information indicating the sentence type of the sentence to be learned based on the sentence to be learned (for example, information indicating which word is the subject, verb, or object of the sentence). The grammar server 7 acquires analysis information from the learning data generation server 3 and receives a grammar information generation request. The grammar server 7 generates grammatical information of a sentence by a known method based on the part of speech and dependency (acceptance information) of each word included in the analysis information, and transmits the grammatical information to the learning data generation server 3.

  The translation server 8 is a server device that provides a translation of a learning target sentence group (word group) acquired from the learning data generation server 3. The translation server 8 stores dictionary information for translation in advance. The translation server 8 acquires a group (for example, phrase, clause) of a sentence to be learned from the learning data generation server 3 and receives the group translation request. The translation server 8 translates each group with reference to the dictionary information for translation, and transmits group translation information, which is information obtained by translating each group, to the learning data generation server 3. The translation method is performed by a known method.

  The voice server 9 is a server device that provides read-out information (voice information) such as a sentence to be learned. The voice server 9 receives a sentence to be learned and also receives a reading information transmission request. When the voice server 9 receives the learning target sentence from the learning data generation server 3, the voice server 9 generates read-out information by a known method and transmits it to the learning data generation server 3. The reading information is reading information for the entire sentence, reading information for each group, reading information for each word, or any one kind of reading information.

  The development server 10 is a server that manages an output program for performing output control (display output control, audio output control) on a learning target sentence in the user terminal 4. When receiving the output program transmission request from the learning data generation server 3, the development server 10 transmits the output program to the learning data generation server 3.

  The user terminal 4 is configured by an information processing terminal such as a tablet terminal or a smartphone, for example, and can access the learning data generation server 3 by a web browser or a dedicated application (not shown).

  The learning data generation server 3 includes, for example, each unit such as an acquisition unit 31, a learning data generation unit 32, and a transmission unit 33 implemented as software.

  The acquisition unit 31 is a part that acquires a learning target sentence from the user terminal 4. The acquisition unit 31 acquires a learning target sentence from the user terminal 4 and accepts a learning data transmission request from the user terminal 4. The acquisition unit 31 sends the acquired sentence to be learned to the learning data generation unit 32.

  The learning data generation unit 32 is a part that generates learning data based on the result of syntax analysis of the learning target sentence. Here, the configuration of the learning data will be described with reference to FIG. FIG. 2 is a diagram conceptually showing learning data. As shown in FIG. 2, learning data is data including a sentence to be learned, analysis information, word semantic information, group information, grammar information, group translation information, reading information, and an output program. It is.

  Group information is information indicating a group of sentences to be learned.

  Returning to FIG. 1, when the learning data generation unit 32 acquires the learning target sentence from the acquisition unit 31, the learning data generation unit 32 transmits the learning target sentence to the syntax analysis server 5 and requests a syntax analysis. When the learning data generation unit 32 receives the analysis information from the syntax analysis server 5, the learning data generation unit 32 transmits the word (morpheme) included in the analysis information and the part of speech information of the word to the dictionary management server 6, and requests a word translation.

  The learning data generation unit 32 acquires word meaning information corresponding to the request from the dictionary management server 6. When the learning data generation unit 32 acquires the word semantic information, the learning data generation unit 32 divides group information in which sentences are divided into groups (groups of phrases and clauses) based on words included in the analysis information, parts of speech of the words, and dependency. Generate. This method of generating group information is performed by combining a known method with dependency information and morphological analysis. In addition, the learning data generation unit 32 transmits analysis information to the grammar server 7, requests grammar information generation, and acquires grammar information from the grammar server 7.

  Subsequently, the learning data generation unit 32 transmits the group information to the translation server 8 and requests group translation. The reason for translating the sentences into groups by translating the sentences into sentences without translating them in sentence units is to help beginners of English improve their ability to translate full sentences themselves with the help of group translation. . The learning data generation unit 32 acquires group translation information that is information obtained by translating group information in response to the group translation request from the translation server 8.

  Subsequently, when the learning data generation unit 32 acquires the group translation information, the learning data generation unit 32 transmits the learning target sentence (or the entire learning target sentence), the group information, and the word to the voice server 9 and also reads the reading information transmission request. do. The learning data generation unit 32 acquires read-out information from the voice server 9 in response to the read-out information transmission request.

  Subsequently, the learning data generation unit 32 requests the development server 10 to transmit an output program. When the learning data generation unit 32 acquires the output program from the development server 10, the learning data generation unit 32 generates learning data including the information generated and acquired above. That is, the learning data generation unit 32 generates learning data including a sentence to be learned, analysis information, dictionary information, group information, grammar information, group translation information, reading information, and an output program. To do. The learning data generation unit 32 sends the generated learning data to the transmission unit 33 in a batch.

  As described above, the parsing server 5, the dictionary management server 6, the grammar server 7, the translation server 8, the speech server 9, and the learning data generation unit 32 of the learning data generation server 3 function as a generation unit.

  The transmission unit 33 is a part that transmits learning data to the user terminal 4. The transmission unit 33 acquires learning data from the learning data generation unit 32 and transmits the acquired learning data to the user terminal 4.

  Next, details of the user terminal 4 will be described. The user terminal 4 includes various units such as a display output unit 41, an audio output unit 42, an input reception unit 43 (acquisition unit), a reception unit 44, and an output control unit 45 (output control unit).

  The display output unit 41 is a part that displays a sentence or the like to be learned. Specifically, the display output unit 41 is a display or the like whose left and right sides of the screen are small compared to the screen of a personal computer.

  The voice output unit 42 is a part that outputs the read-out information as a voice. Specifically, the audio output unit 42 is a speaker or the like.

  The input receiving unit 43 is a part that receives an input of a learning target sentence, transmits the learning target sentence to the learning data generation server 3, and requests transmission of learning data. Here, an example of a sentence to be learned is shown in FIG. The learning target sentence is, for example, an English news article published on the site. The input receiving unit 43 acquires information including the learning target sentence acquired with permission from the publishing site. As a method of acquiring from a publishing site, there is RSS or the like.

  When a file including a learning target sentence is specified on the input screen, the input receiving unit 43 transmits a sentence having the content of the file to the learning data generation server 3 and requests transmission of learning data. Here, FIG. 4 shows an example of the input screen.

  FIG. 4A is a screen of the user terminal 4 that specifies a file including a sentence to be learned. First, by the user's operation (for example, manual input operation by the user), the address of the file is directly input to the file storage destination input field 431, or the reference button 432 is pressed, and the address of the file is selected. Is done. Subsequently, when the upload button 433 is pressed by the user's operation, the input reception unit 43 sends the sentence of the contents of the file indicated by the address input in the file storage destination input field 431 to the learning data generation server 3. Along with transmission, a transmission request for learning data is made.

  In addition, when a learning target sentence is input on the input screen, the input receiving unit 43 may transmit the learning target sentence to the learning data generation server 3 and also make a learning data transmission request. For example, in an input screen having a learning target sentence input area 434 as shown in FIG. 4B, the user's operation leads to the learning target sentence input area 434 as in FIG. 4A. When a learning target sentence is input and the analysis start button 435 is pressed, the input receiving unit 43 transmits the learning target sentence to the learning data generation server 3 and requests transmission of learning data.

  Further, the input receiving unit 43 may receive an input of a URL (Uniform Resource Locator) indicating a web page on which the learning target sentence is posted, and extract the learning target sentence on the URL. . For example, an input screen having a URL input field 436 as shown in FIG. Similarly to FIG. 4A, a URL indicating the web page is directly input to the URL input field 436 by the user's operation. Subsequently, when the analysis start button 437 is pressed by the user's operation, the input receiving unit 43 transmits the sentence posted on the web page corresponding to the input URL to the learning data generation server 3. Request transmission of learning data.

  The receiving unit 44 is a part that receives learning data from the learning data generation server 3. When receiving the learning data from the learning data generation server 3, the receiving unit 44 sends the learning data to the output control unit 45. The receiving unit 44 may store the received learning data once and send the learning data to the output control unit 45 at a predetermined timing.

  The output control unit 45 is a part that performs output control of the learning target sentence based on the learning data. For example, the output control unit 45 changes the display mode of the word of the sentence based on the dependency of the sentence indicated by the dependency information included in the analysis information of the learning data, and outputs the display to the display output unit 41. Further, the output control unit 45 outputs the meaning of each word specifying the part of speech of the parsed sentence based on the word meaning information of the learning data.

  Further, the output control unit 45 outputs translation information based on the translation result (group translation information) for each group of sentences based on the result of the syntax analysis. Further, the output control unit 45 outputs information indicating the sentence pattern based on the grammatical information included in the learning data. Further, the output control unit 45 outputs the read-out information included in the learning data as a voice from the voice output unit 42.

  In addition, the output control part 45 exhibits a function by installing the output program contained in learning data. An output program may be installed in advance before acquiring learning data.

  Here, the aspect displayed on the user terminal 4 is demonstrated using FIGS. First, FIG. 5 shows a display example of the initial screen. FIG. 5A shows an initial screen displayed for each sentence (sentence). When “sentence” is selected in the display check button 436, the output control unit 45 displays a target sentence for each sentence. When “only root word” is selected in the sentence check button 437, the output control unit 45 highlights and displays the root word (reference word) for each sentence.

  The root word is the most important word in the sentence (for example, the verb of the main sentence is defined as the root word in the sentence). In this way, the output control unit 45 can easily understand the meaning of each sentence by highlighting the root word. In the first sentence of the sentence shown in FIG. 5A, “type” becomes the root word, and in the next sentence, “present” becomes the root word.

  Further, the output control unit 45 displays the meaning of the important word for each sentence in the meaning display area 438 under the sentence display. This important word is a word in which information indicating that it is an important word is included in the word semantic information acquired from the dictionary management server 6. Further, the output control unit 45 displays the voice button 439 in association with the sentence. When the voice button 439 is pressed by a user operation, the output control unit 45 outputs the corresponding sentence reading information from the voice output unit 42 as a voice.

  FIG. 5B is an initial screen displaying the whole sentence. When “full text” is selected in the display check button 436, the output control unit 45 displays the full text with the root word highlighted. Thus, in response to the selection of “full text” or “sentence” in the display check button 436, the output control unit 45 switches between sentence display and full text display. Further, the output control unit 45 displays the important words of the whole sentence in the semantic display area 438 immediately below. Further, the output control unit 45 displays a voice button 439 in association with the entire sentence. When the voice button 439 is pressed by a user operation, the output control unit 45 outputs the full text reading information from the voice output unit 42 as a voice.

  Next, a display example when a displayed word is tapped will be described with reference to FIG. FIG. 6A shows an example in which a certain word (structure in the example shown in the figure) is tapped when displayed for each sentence. When detecting that a certain word has been tapped, the output control unit 45 acquires the meaning of the word from the learning data, and displays and outputs the meaning. When the target word has a plurality of part of speech meanings, the output control unit 45 displays the meaning corresponding to the part of speech obtained by the syntax analysis in the sentence.

  Further, the output control unit 45 highlights the words corresponding to the dependency parent and child of the tapped word with different colors and fonts. The output control unit 45 refers to the reception information, and the root word, the word corresponding to the parent, the word corresponding to the child immediately below the parent, and the child word immediately below the parent are different from each other. Highlight with color or font. In other words, the output control unit 45 changes the display mode of the words in the dependency parent-child relationship with the designated word and displays them.

  For example, the output control unit 45 corresponds to a red gothic character as a root word, a brown gothic character as a parent word, an italic character in another font in green, and a word immediately below as a word corresponding to a child immediately below. Highlight words in blue italic letters. When the legend 440 is pressed, the output control unit 45 displays the color coding and font examples described above as a legend. The display mode may be changed in other modes based on the dependency parent-child relationship. For example, it may be displayed in a character background color font that differs between the parent and child. Similarly to the example shown in FIG. 5A, when the voice button 439 is pressed by a user operation, the output control unit 45 outputs the corresponding sentence reading information from the voice output unit 42 as a voice.

  FIG. 6B shows an example when a certain word is tapped when the full sentence is displayed. When the output control unit 45 detects that a certain word has been tapped, the output control unit 45 acquires the meaning of the word from the learning data, and displays and outputs the meaning. Further, the output control unit 45 highlights the words corresponding to the dependency parent and child of the tapped word in different colors, fonts, character background colors, and the like. Similarly to the example illustrated in FIG. 5B, when the voice button 439 is pressed by a user operation, the output control unit 45 outputs the full-text reading information from the voice output unit 42 as a voice.

<Process flow>
FIG. 12 is a diagram showing an overview of an example of the flow of output control processing in the present embodiment. First, the input receiving unit 43 transmits a sentence of the contents of the file indicated by the address input in the file storage destination input field 431 to the learning data generation server 3 and requests transmission of learning data (S1). In response to this, the acquisition unit 31 acquires a learning target sentence from the user terminal 4 and accepts a learning data transmission request from the user terminal 4 (S2).

  When the learning data generation unit 32 acquires the learning target sentence from the acquisition unit 31, the learning data generation unit 32 transmits the learning target sentence to the syntax analysis server 5, requests a syntax analysis, and receives analysis information from the syntax analysis server 5. (S3). Subsequently, the learning data generation unit 32 transmits the word included in the analysis information and the part-of-speech information of the word to the dictionary management server 6 and acquires word semantic information from the dictionary management server 6 (S4).

  When the learning data generation unit 32 acquires the analysis information, the learning data generation unit 32 generates group information such as a main clause, a clause, a phrase, and a word group based on the analysis information. Further, the learning data generation unit 32 transmits the analysis information to the grammar server 7 and requests generation of the grammar information to acquire the grammar information from the grammar server 7 (S5). The learning data generation unit 32 transmits the group information to the translation server 8 and requests group translation. The learning data generation unit 32 acquires group translation information that is information obtained by translating the group information in response to the group translation request from the translation server 8 (S6).

  Subsequently, when the learning data generation unit 32 acquires the group translation information, the learning data generation unit 32 transmits a learning target sentence, group information, and a word to the voice server 9 and requests a reading information transmission. The learning data generation unit 32 acquires read-out information from the voice server 9 in response to the read-out information request (S7). The learning data generation unit 32 generates learning data including the acquired / generated information (learning data obtained by collecting the acquired / generated information), and the transmission unit 33 transmits the learning data to the user terminal 4 ( S8).

  The receiving unit 44 receives the learning data (S9), and the output control unit 45 performs output control using the learning data (S10). As the output control, the output control unit 45 performs display output to the display output unit 41 while changing the display mode of the word of the sentence based on the dependency of the sentence indicated by the dependency information of the analysis information.

  As described above, according to the learning system 1 according to the embodiment of the present invention, the output control unit 45 has the dependency information of the analysis information included in the learning data generated by the learning data generation unit 32. Since the display mode of the word of the sentence is changed based on the dependency of the sentence to be displayed and output to the display output unit 41, even if the sentence to be learned is presented to the user terminal 4 which is a small screen device on the left and right , You can easily understand the structure of the sentence.

  In addition, the output control unit 45 changes the display mode of the words that are in the parent-child relationship of the dependency with the word specified (tapped) by the user and outputs the display, so that it has a parent-child relationship with the word specified by the user. By changing the display mode of the word, the display mode is changed to a portion desired by the user, and the structure of the sentence can be understood more easily.

  In this way, the learning system 1 displays the information in a compact and easy-to-understand form without displaying it in an academic and complex manner as in the prior art. The complicated display contents of the dependency can be expressed simply.

  In addition, when the root word is tapped, the output control unit 45 changes the display mode of the word having a dependency relationship with the root word and outputs it, so that the word that is related to the more important word in the sentence is displayed. By changing the mode, the structure of the sentence can be understood more easily.

  Further, since the output control unit 45 displays and outputs words in different colors for each hierarchy of dependency parent-child relationships, the dependency can be understood without adding an arrow indicating the dependency as in the prior art. Can do.

  Further, the output control unit 45 uses morphological analysis and syntax analysis to specify the part of speech of the word and display the meaning of the specified part of speech, so that it is possible to display the exact meaning of the word.

  Further, the output control unit 45 outputs group translation information included in the learning data. In this way, the output control unit 45 outputs the translation result (group translation information) for each group of sentences (for example, noun phrases, verb phrases), so that the beginner of language can more easily It is possible to guide for translation.

  An English sentence consists of words, phrases, and phrases consisting of multiple words. However, most of the words only make sense when combined with other words. In English, all words belong to some kind of word group. Parsing shows well that English sentences consist of various word groups. If this parsing is further analyzed, clauses, phrases and word groups are identified and extracted, and the English sentences are interpreted for each word group, it will be much easier to understand the structure and meaning of the sentence than it is to interpret the whole sentence suddenly. become.

  Until now, there has been a technique for delimiting sentences and interpreting them, but they are mechanically delimited by parts of speech and the like, and are not based on parsing. This system identifies and separates main clauses, clauses, phrases, and word groups, which are essential semantic groups of sentences, by syntactic analysis, which is different from conventional methods.

  Further, the output control unit 45 further outputs the grammar information included in the learning data, so that the learning system 1 can simplify the complicated display contents of each English grammar even in the user terminal 4 having a small screen. It can be expressed.

  In addition, the output control unit 45 outputs the read-out information included in the learning data by voice according to the designation from the user, so that the structure of the sentence can be understood from the ear more easily than when only the display is performed. be able to. In addition, the output control unit 45 can output voice more finely when outputting the reading information divided for each group.

  For example, there are the following effects. A sentence consisting of multiple sections can be read out separately for each section. As a result, the learner can accurately understand the sentence breaks and proceed with reading English from the ear. In addition, beginners will be able to read English more easily, and English will be heard more appropriately.

  In addition, the learning system 1 reads out the word group unit such as a section unit with a short interval, so that the user can continue to read this example and the shadow wing is uttered by the user. It becomes possible. The shorter the reading unit, the easier the shadow wing will be, and not only will users at various levels read, listen to and understand, but will also be able to train to speak. That is, the learning system 1 can support learning from a plurality of angles of reading, listening, and speaking for the user of the user terminal 4.

  In general, the dependency syntax differs greatly between English and Japanese, and this is said to be one of the reasons that makes learning English difficult for Japanese. Japanese dependency is usually left-to-right in the order of the sentences, and many of the most important root words that are the parents of all dependency are located last. On the other hand, English sentences always have a dependency that returns the word order from right to left, and are mixed with a dependency from left to right. Most root words are in the sentence. As described above, the learning system 1 expresses the dependency parent-child relationship by changing the display mode of the word or presents the semantic translation of the word group. It can help with grasping powerfully.

  In the above-described embodiment, the learning data generation server 3 transmits information (learning data) in which analysis information, word semantic information, grammatical information, and the like are collected to the user terminal 4. Thus, once the learning data is received, the user terminal 4 does not need to communicate with the learning data generation server 3 even when trying to switch and display the learning target sentence. As an example of switching and displaying the learning target sentence, switching from the display of only the root word to the display of the word group is applicable.

  In the above-described embodiment, the server group (the learning data generation server 3, the syntax analysis server 5, the dictionary management server 6, the grammar server 7, the translation server 8, the voice server 9, and the development server 10) and the user terminal 4 Although the case of configuring the learning system 1 has been described, the user terminal 4 may have all the functions of the server group. The functions of the server group may be realized by a single server.

  Although not particularly described in the above-described embodiment, as shown in FIG. 13, a tree display style devised so that the dependency list can be displayed in an easy-to-understand manner even on a compact smartphone screen is conceivable. This technique realizes display using five symbols at the bottom of FIG. In this tree display style, the word order of sentences is arranged vertically from the top, and it is possible to point to the parent of each word, and even on a small smartphone screen, you can check all the parent-child relationships of the dependency while scrolling vertically . Devices such as smartphones exhibit excellent performance in scrolling up and down even if the left and right sides of the screen are small. The ease of use of the scroll may outperform the PC. The display example of FIG. 13 uses this feature. The dependency relationships of all the words shown in FIG. 7 are displayed by arranging the words in the sentence in the vertical order. Here, grammar display such as SVO of main sentence and clause is also performed. The learner can easily understand the whole dependency of sentences by using smooth scrolling even if the screen is small to the left and right.
