Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram showing a configuration of an electronic circuit of a search device according to an embodiment of the present invention.

In this embodiment, an example in which the search device is configured as, for example, an electronic dictionary 10 will be shown. The search device can be realized by various electronic devices such as a personal computer, a smartphone, and a tablet PC in addition to the electronic dictionary 10.

In the electronic dictionary 10, information on at least one word meaning corresponding to each of a plurality of headwords is recorded as dictionary data. The dictionary data includes an example (example sentence) including a word of a headword corresponding to a word meaning, and a phrase (idiom) including a headword. The electronic dictionary 10 is a word search for searching information including a word meaning and an example corresponding to a headword by inputting a character string (a word to be a search word) for designating a headword, and one or a plurality of words constituting a phrase. A phrase search that searches for a phrase by entering a character string that includes the word, and a word with a contained sentence that executes a word search and a phrase search by entering a sentence that includes the search term (hereinafter referred to as a contained sentence) together with the search term. It has a search function that can execute a search.

In the word search with a contained sentence, the electronic dictionary 10 executes a syntactic analysis on the contained sentence including the search term input as the search target, and executes a search using the syntactic analysis result. Further, the electronic dictionary 10 executes parsing not only for the contained sentences but also for the examples corresponding to each of the plurality of word meanings registered in advance in the dictionary data, and the syntactic analysis results for the examples and the syntactic analysis results for the contained sentences are obtained. Based on the comparison (similarity) of, it is possible to search for word meanings and examples corresponding to the search term.

The electronic dictionary 10 has a computer configuration in which a program recorded on various recording media or a transmitted program is read and the operation is controlled by the read program, and the electronic circuit thereof includes a CPU ( Central processing unit) 11 is provided.

The CPU 11 functions as a control unit that controls the entire electronic dictionary 10. The CPU 11 is a server through a control program stored in advance in the memory 12, a control program read from a recording medium 13 such as a ROM card into the memory 12 via the recording medium reading unit 14, or a network N including the Internet or the like. The operation of each part of the circuit is controlled according to the control program downloaded from 20 via the communication unit 15 and read into the memory 12.

The control program stored in the memory 12 is an input signal according to a user operation from the key input unit 16, an input signal according to a user operation from the touch panel display unit 17, or a server 20 on the network N connected externally. It is activated according to the communication signal with the recording medium 13 such as EEPROM (registered trademark), RAM, and ROM connected via the recording medium reading unit 14.

A memory 12, a recording medium reading unit 14, a communication unit 15, a key input unit 16, a touch panel type display unit 17, and the like are connected to the CPU 11.

The control program stored in the memory 12 includes a system program that controls the overall operation of the electronic dictionary 10, a server 20 on the externally connected network N, and a communication program for data communication with other electronic devices such as a personal computer. Is remembered. Further, the memory 12 stores a dictionary control program 12a that executes a search function that searches for information based on the input character string (search term) and outputs the information. The dictionary control program 12a includes a syntactic analysis program 12b that executes syntactic analysis on sentences such as contained sentences and examples.

Further, the memory 12 records dictionary data 12c, search key data 12d, first similarity data 12e, phrase candidate list data 12f, second similarity data 12g, search term data 12h, contained sentence data 12k, and the like. ..

The dictionary data 12c includes, for example, a database (dictionary content data) in which a plurality of dictionaries such as an English-Japanese dictionary, a Japanese-English dictionary, an English-English dictionary, and a Japanese dictionary are collected. The dictionary data 12c includes word meaning information for explaining the meaning (word meaning) corresponding to each headword for each dictionary. A plurality of word meaning information may be stored for one headword. In addition, the word meaning information includes an example showing an example of use in a sentence according to the meaning of the headword (word), and information of a phrase including the headword (word).

A word search and a phrase search can be executed on the dictionary data 12c. Therefore, the dictionary data 12c is provided with, for example, a word meaning search index 12c1 for word search and a phrase search index 12c2 for phrase search, which uses a text search algorithm with a ranking function based on an N-gram-based search index. The word meaning search index 12c1 is an index that defines a word meaning part that can handle the inside of the explanation part in which the explanation of the headword is described in the word meaning unit and ranks the dictionary content data by the word meaning unit. .. The phrase search index 12c2 is an index that defines a phrase portion of dictionary content data by collecting the places where phrases using headwords are described. That is, the dictionary data 12c in the present embodiment is used as word dictionary data in which a search is executed using the word meaning search index 12c1 and phrase dictionary data in which a search is executed using the phrase search index 12c2.

The dictionary data 12c may be acquired from a dictionary database (for example, a server 20) accessible through the network N without being built in the main body of the electronic dictionary 10.

The search key data 12d is data indicating a search key for a search term, which is generated based on the result of parsing the contained sentence. The search key is, for example, the basic form of the search word, part of speech, verb type (transitive verb / automatic verb), sentence pattern type (SVC, SVO, SVOO, SVC, etc.). It is composed of unique expression information (place, time, etc.) and syntactic features (infinitive, etc.) of the recipient. For example, in the case of the contained sentence "The boy toy a way from brother." And the search term "took", "take verb transitive verb SVOM from" is generated as a search key. The search key may include at least the basic form of the search term and data of any other syntactic analysis result.

The first similarity data 12e is data showing the similarity (first similarity) indicating the comparison result between the example of the word meaning corresponding to the search word searched by the word search by the word search with the contained sentence and the contained sentence. Is. The degree of similarity between the example of the meaning and the contained sentence (first degree of similarity) is based on, for example, the number of matches of the dependency type (dependency relationship tag) extracted by parsing. That is, the more the same dependency type (dependency-related tag) is, the higher the similarity is assumed. Furthermore, if there are multiple parsing information (examples) with the same number of matches of the dependency type (dependency relationship tag), the headwords in the dependency relationship with the same dependency type (dependency relationship tag) The one with the smaller distance from other words is judged to have the higher degree of similarity.

The phrase candidate list data 12f is data indicating a phrase candidate list in which phrases corresponding to the search terms are registered, which is searched by a phrase search by a word search with a contained sentence (see FIG. 8).

The second similarity data 12g is data showing the similarity (second similarity) indicating the comparison result between the phrase candidate registered in the phrase candidate list and the contained sentence. The similarity between the phrase candidate and the contained sentence (second similarity) is, for example, the number of words constituting the phrase candidate, the number of words constituting the contained sentence, and the number of words in which the word constituting the phrase candidate and the contained sentence match. The evaluation value (score) calculated based on is used (details will be described later).

The search term data 12h is the input search term data. The contained sentence data 12k is data indicating the contained sentence input together with the search term.

FIG. 2 is a front view showing the external configuration of the electronic dictionary 10.

In the case of the electronic dictionary 10 in FIG. 2, the CPU 11, the memory 12, the recording medium reading unit 14, and the communication unit 15 are built in the lower side of the apparatus main body to be opened and closed, and the key input unit 16 is provided, and the touch panel is provided on the upper side. The expression display unit 17 is provided.

The key input unit 16 includes a character input key 16a, a dictionary selection key 16b that can select various dictionaries and various functions, a [translation / decision] key 16c, a [back] key 16d, and a cursor key (up / down / left / right keys). It is equipped with 16e, a power button, and various other function keys. On the touch panel type display unit 17, various menus, buttons 17a, and the like are displayed according to the execution of various functions.

The electronic dictionary 10 can input an instruction by the user according to an operation on the key input unit 16 by the user or a touch operation (with a pen tip or a fingertip) on a menu or a button displayed on the display unit 17.

In the electronic dictionary 10 configured in this way, the CPU 11 controls the operation of each part of the circuit according to the instruction described in the dictionary control program 12a, and the software and the hardware operate in cooperation with each other to perform the following operations. Realize the functions described in the description.

Next, the operation of the electronic dictionary 10 in this embodiment will be described.

FIG. 3 is a flowchart showing the dictionary control process (main process) by the electronic dictionary 10 in the present embodiment, and FIG. 4 is a flowchart showing the display control process of the flowchart shown in FIG.

When the power is turned on, the CPU 11 activates the dictionary control program 12a to start the dictionary control process. The CPU 11 causes the touch panel type display unit 17 to display the home screen, which is the initial screen. The home screen includes a menu for selecting the dictionary to be searched. In the menu, you can select the dictionary to be searched. For example, as a dictionary to be searched, a specific range of dictionaries (for example, English-based dictionaries) or a specific dictionary (for example, XX English-Japanese dictionary) that searches all dictionaries can be selected. it can.

When a dictionary to be searched is selected in the menu, the CPU 11 causes the touch panel display unit 17 to display a search screen provided with an input area for inputting a search term.

FIG. 5 is a diagram showing an example of the search screen AR1 for phrase search in the present embodiment. As shown in FIG. 5, the search screen AR1 is provided with an input area AR11 for inputting a character string as a search term. When the character string (search term) is input to the input area AR11 (step A1), the CPU 11 stores the search term data 12h of the input search term in the memory 12. When the search execution is instructed by, for example, the operation of the [translation / decision] key 16c, the CPU 11 determines that the phrase search does not include a contained sentence because it is an input to the search screen for the phrase search (step A2). , No → step A10, “phrase search”), start phrase search based on the entered search term.

The CPU 11 specifies the search term data 12h of the search term (one or more) that specifies the phrase stored in the memory 12 (step A31), and uses the word meaning search index 12c1 to search for the phrase corresponding to the search term. Search from the phrase dictionary data (step A32).

The CPU 11 records the phrase searched from the phrase dictionary data in the phrase candidate list, and displays the search result of the phrase search on the touch panel display unit 17 (step A33).

FIG. 6 is a diagram showing an example of the search result screen AR2 for displaying the search results of the phrase search in the present embodiment. As shown in FIG. 6, the search result screen AR2 has a phrase list area AR21 that displays a plurality of phrases searched by the phrase search, and an example display area AR22 that displays an example using the phrase displayed in the phrase list. Is provided.

A plurality of phrases including a search term are displayed in a list in the phrase list area AR21, and an example including a phrase selected in the phrase list area AR21 is displayed in the example display area AR22. For example, in the example shown in FIG. 6, the phrase "take the cake" including the search term "cake" is selected, and the example "That takes the cake." And the translation "terrible, the worst" using this phrase are It is displayed.

The order of displaying the phrases listed in the phrase list area AR21 is the order registered in the phrase dictionary data.

On the other hand, when executing a word search, when a character string as a search term is input to the search screen for word search in the same manner as the phrase search described above, the CPU 11 searches for the input search term. The word data 12h is stored in the memory 12. When the search execution is instructed by, for example, the operation of the [translation / decision] key 16c, the CPU 11 determines that the search is a word search because it is an input to the search screen for the word search (step A2, No → step A10). , "Word search"), start a word search based on the entered search term.

The CPU 11 specifies the search term data 12h of the search term stored in the memory 12 (step A11), and uses the word meaning search index 12c1 to search for information including word meanings and examples corresponding to the headwords corresponding to the search terms. Search from the dictionary data (step A12). If there are multiple meanings for the headword, information on multiple meanings and examples is searched.

The CPU 11 causes the touch panel display unit 17 to display information including each word meaning and each example searched from the word dictionary data (step A13).

Next, a case of executing a word search with a contained sentence will be described.

FIG. 7 is a diagram showing an example of the search screen AR3 for searching for words with contained sentences in the present embodiment. As shown in FIG. 7, the search screen AR3 is provided with an input area AR31 for inputting a character string as a search term and an input area AR32 for inputting a contained sentence. When the character string (search term) is input to the input area AR31 (step A1) and the character string (contained sentence) including the search term is input to the input area AR32 (step A2, Yes), the CPU 11 is input. The search term data 12h of the search term and the contained sentence data 12k of the contained sentence are stored in the memory 12. When the search execution is instructed by, for example, the operation of the [Translation / Enter] key 16c, the CPU 11 determines that the search screen has a contained sentence and inputs the input because it is an input to the search screen for searching for a word with a contained sentence. Start the process for searching for words with contained sentences based on the search words and contained sentences.

In the above description, the search term and the contained sentence are input through the search screen AR3 for searching the word with the contained sentence, but the search term and the contained sentence may be input by another method. For example, according to the touch operation (with the pen tip or fingertip) for the sentence displayed in the sentence display area, the word at the touch position is specified as a search word, and the text data of one sentence including this word is extracted and contained. Enter as a statement. The CPU 11 stores the specified word as the search word data 12h, and stores the text data extracted from the sentence as the contained sentence data 12k in the memory 12. As a result, it is possible to easily input the search term and the contained sentence and execute the word search with the contained sentence only by the touch operation on the displayed sentence.

The CPU 11 executes a parsing process by the parsing program 12b on the input contained sentence (contained sentence data 12k) (step A3). In the parsing process, data required for generating a search key, data related to the dependency type (dependency-related tag), and the like are detected.

The CPU 11 creates a search key based on the result of parsing the contained sentence, and stores the search key data 12d in the memory 12 (step A4). As described above, the search key includes, for example, the basic form of the search term, the part of speech, the verb type, the sentence pattern type, the preposition of the dependency of the search term, the named entity information of the dependency of the search term, the syntactic feature, and the like.

When the CPU 11 inputs to the search screen for searching for words with contained sentences or executes a word search with contained sentences because a word in the sentence displayed in the sentence display area is designated as a search word (step A10). , "Word search with contained sentences"), word search by search term is performed using the search key, and phrase search is performed using the basic form of the search term in the search key.

First, the CPU 11 specifies a search term for word search and a contained sentence including the search term to be searched (steps A21 and A22). The CPU 11 searches the word dictionary data for information including word meanings and examples corresponding to the headwords corresponding to the search words using the word meaning search index 12c1 (step A23).

Next, the CPU 11 calculates the first similarity degree showing the comparison result between the contained sentence and the example of each word meaning searched by the word search based on the syntactic analysis (step A24). That is, the CPU 11 calculates the similarity (first similarity) between the example of each word meaning and the contained sentence based on the number of matches of the dependency type (dependency relationship tag) extracted by parsing, for example. The first similarity data 12e indicating the first similarity for each example is stored in the memory 12.

Further, the CPU 11 searches the phrase dictionary data for the phrase corresponding to the input search term using the word meaning search index 12c1 and registers it in the phrase candidate list (step A25).

Next, the CPU 11 calculates a second similarity degree indicating the comparison result with each phrase for the contained sentence for each of the phrases registered in the phrase candidate list based on the syntactic analysis, and the second similarity degree for each phrase. 12 g of data is stored in the memory 12 (step A26). The CPU 11 determines the degree of similarity (second similarity) with each phrase to the contained sentence, for example, the number of words constituting the phrase candidate, the number of words constituting the contained sentence, and the phrase candidate obtained by the parsing process. It is calculated based on the number of words that match the words to be written and the contained sentences.

FIG. 8 is a diagram for explaining a method of calculating an evaluation value (score) corresponding to the second degree of similarity in the present embodiment. Here, the evaluation value is calculated based on the number of matches between the plurality of words included in the contained sentence and the plurality of words included in the phrase.

In FIG. 8, for each of the plurality of phrases (phrase candidates) registered in the phrase candidate list, the number of words constituting the phrase candidate (number of words PhraseSize), the number of words constituting the contained sentence (number of words SentenceSize), and the phrase The number of words (word count) in which the words constituting the candidate and the contained sentence match is shown.

The CPU 11 calculates the evaluation value based on the following formula. The evaluation value calculated based on the following formula indicates that the smaller the numerical value, the higher the similarity.

Number of words PhraseSize − When the number of words Count ≠ 0 Evaluation value = (Number of words SentenceSize) / (Number of words PhraseSize)… (1)
Number of words PhraseSize − When the number of words Count = 0 Evaluation value = 1 / (Number of words PhraseSize)… (2)
For example, the phrase candidate “a piece of cake” shown in FIG. 8 has a (word number PhraseSize) of “4”, and the word number (word number SentenceSize) constituting the contained sentence input in the input area AR32 shown in FIG. 7 is “4”. 10 ”and (word count) are“ 4 ”. In this case, since (the number of words PhraseSize) and (the number of words Count) are equal, the evaluation value = 1/4 = 0.250 is calculated based on the equation (2).

Further, in the phrase candidate "take the cake" shown in FIG. 8, the (word number PhraseSize) is "3", the number of words constituting the contained sentence (word number SentenceSize) is "10", and the (word number Count) is "1". It becomes. In this case, since (the number of words PhraseSize) and (the number of words Count) are not equal, the evaluation value = 10/3 = 3.333 is calculated based on the equation (1).

In the above-mentioned explanation, the evaluation value is calculated based on the above-mentioned equations (1) and (2), but in order to change the priority when there are phrases with the same evaluation value, each phrase or phrase is used. The weighting may be set in advance for the included words, and the second similarity may be obtained.

The CPU 11 is a display control for displaying information on each word meaning, each example, and each phrase searched based on the input search word and the contained sentence based on the first similarity degree and the second similarity degree. Is executed (step A27).

The CPU 11 performs display control processing according to the flowchart shown in FIG. 4, for example. FIG. 9 is a diagram showing an example of the search result screen AR4 that displays the search results of the word search with the contained sentence in the present embodiment. As shown in FIG. 9, the search result screen AR4 has a phrase list area AR41 that displays a plurality of phrases searched by the phrase search, and a phrase example display area that displays an example using the phrase displayed in the phrase list. AR42 and a word meaning example display area AR43 for displaying word meanings and examples searched by word search are provided.

The CPU 11 displays the word meanings and examples searched by the word search in the word meaning example display area AR43 (step B1), giving priority to the first one having a high degree of similarity, and displays the phrases and phrases searched by the phrase search. The examples used are displayed in the phrase list area AR41 and the phrase example display area AR42, respectively, with priority given to the second one having a high degree of similarity (step B2).

In the search result screen AR4 shown in FIG. 9, the highest priority word meaning “cake” and example sentence 1 “I like the cake.” Are displayed at the head of the word meaning example display area AR43. Other meanings and example sentences are displayed after the second, but here they are hidden because the display area is set narrow, and they are displayed according to the scroll operation. Further, as a result of the phrase search, the order of a plurality of phrases set in the phrase candidate list is sorted according to the second similarity (evaluation value) and displayed in a list in the phrase list area AR41. In FIG. 9, the phrase "a piece of cake" is displayed at the beginning, and the other phrases are displayed after the second phrase. Formulaics that cannot be displayed in the display area can be displayed according to the scroll operation. Immediately after the search, the phrase displayed at the beginning of the phrase list area AR41 is automatically selected, and an example including the selected phrase is displayed in the phrase example display area AR42. There is. Example of phrase The example of the phrase to be displayed in the display area AR42 can be switched by designating a desired phrase in the phrase list area AR41 by a touch operation or the like.

In other words, when prioritizing display, the display position of the phrase that is preferentially displayed in the display area is fixed and easy to see, and the beginning that is displayed without hiding without scrolling in the initial state. It can be displayed in a part or automatically displayed in the display area without any special additional operation.

In the above description, the display control is performed to prioritize and display the first similarity and the second highest similarity, but the similarity is selectively equal to or higher than a predetermined value or only a predetermined number is selectively selected from the higher ranks. Display control may be performed such as displaying or displaying by a list sorted in order from the one having the highest degree of similarity.

In this way, in the search process with a contained sentence in which the search term and the contained sentence are input, the phrase candidate is displayed based on the comparison between the phrase candidate searched from the phrase dictionary data and the contained sentence (calculation of the second similarity). It is also possible to display the meaning of the word as a result of the word search based on the search term. Even if the user does not understand whether the word that the user wants to search is used in the normal meaning or as a phrase, just by performing a normal word search, it can be used as a search term in a contained sentence including the search term. Appropriate search results are displayed, so you can effectively know the meaning and usage of a word or a phrase containing a word.

In addition, for a plurality of phrase candidates set in the phrase candidate list, they are sorted in order of priority based on the comparison result (second similarity) with the contained sentence, so that the search term and the contained sentence are displayed. You can effectively know the meaning and usage of the corresponding phrase.

Further, on the search result screen AR4, a plurality of phrases searched by the phrase search, word meanings and examples searched by the word search, and examples using the phrases displayed in the phrase list are displayed. The meaning of the search term used in the phrase may be different from the meaning searched by the word search, so it is easy to make the difference by displaying the example and the meaning using the phrase together. Can be grasped.

Further, in the above description, the phrase including the search term is searched from a plurality of phrases stored in the phrase dictionary data, but it is possible to execute the phrase search using another processing procedure. For example, each of a plurality of phrases stored in the phrase dictionary data is compared with the contained sentence, and among the phrases whose comparison result satisfies a predetermined condition, the phrase including the search term is selected and displayed, or this comparison is performed. It is possible to control the display so that the phrases that do not include the search term are excluded when the phrases are displayed in the priority order based on the result.

In the above-mentioned display control process, the first similarity is used to control the display of the word meaning and the example, and the second similarity is used to control the display of the phrase. However, the first similarity and the second are the second. The similarity of the above may be integrated to control the display of information on word meanings, examples, and phrases.

In this case, the CPU 11 performs display control processing according to the flowchart shown in FIG. 10, for example.

In this case, the CPU 11 normalizes the first similarity and the second similarity (step C1). As a normalization method, for example, the maximum value and the minimum value that the first similarity can take and the maximum value and the minimum value that the second similarity can take are associated with each other, and the first similarity and the first are the same. The correspondence with the similarity of 2 is defined. The CPU 11 converts the first similarity degree and the second similarity degree obtained by the search process based on the above-mentioned correspondence relationship to obtain the third similarity degree.

The method of similar normalization is not limited to the above-mentioned method, and other methods may be used as long as the similarities obtained by different methods can be integrated. Further, either the first similarity degree or the second similarity degree may be weighted, and the priority may be normalized so that either priority has a greater influence on the display control.

Based on the third degree of similarity normalized in this way, the CPU 11 executes display control for preferentially displaying word meanings, examples, and phrases having a high degree of similarity (step C2).

In this way, the first similarity and the second similarity are normalized, and the display control of word meanings, examples, and phrases is performed based on the normalized similarity, so that the input search term and the contained sentence can be adjusted. It is possible to integrate the meanings, examples, and phrases, change the priority order, and present it to the user.

Next, a modified example of the dictionary control process (main process) by the electronic dictionary 10 in the present embodiment will be described. FIG. 11 is a flowchart showing a modified example of the dictionary control process (main process) by the electronic dictionary 10 in the present embodiment.

In the dictionary control process shown in FIG. 3, a word search, a phrase search, and a word search with a contained sentence are executed individually, but in a modified example of the dictionary control process shown in FIG. 11, the input search word and the contained sentence are executed. Based on the sentence, word search and phrase search are executed, and the search result (word meaning, example, phrase) is based on the similarity calculated in the search process (first similarity, second similarity). Controls whether or not is displayed.

The CPU 11 inputs the search term and the contained sentence in the same manner as in the word search with the contained sentence described above, and in the same manner as in steps A23 and A24 shown in FIG. 3, the word meaning and the example corresponding to the headword corresponding to the search term. The information to be included is searched from the word dictionary data using the word meaning search index 12c1, and the first similarity indicating the comparison result between the contained sentence and the example of each word meaning searched by the word search is calculated based on the parsing. (Steps D1 and D2)
Here, the CPU 11 causes the touch panel type display unit 17 to display the corresponding word meaning and example when there is a word meaning and example having a first degree of similarity equal to or higher than a predetermined value (step D3, Yes) (step D4).

On the other hand, when there is no meaning or example in which the first degree of similarity is equal to or higher than a predetermined value (step D3, No), the CPU 11 performs a phrase corresponding to the input search term in the same manner as in step A25 shown in FIG. , The word meaning search index 12c1 is used to search from the phrase dictionary data, and the second similarity indicating the comparison result with each phrase for the contained sentence is calculated based on the parsing (step D6).

Here, when there is a phrase whose second similarity is equal to or higher than a predetermined value (step D7, Yes), the CPU 11 displays the corresponding phrase on the touch panel display unit 17 (step D8).

When there is no phrase whose second similarity is equal to or higher than a predetermined value (step D7, No), the CPU 11 causes the touch panel display unit 17 to display all the word meanings, examples, and phrases searched by the word search and the phrase search. (Step D9).

In this way, in the modified example of the dictionary control process, in the word search with the contained sentence, the search result (word meaning, example, phrase) is based on the similarity calculated in the search process (first similarity, second similarity). ) Can be controlled.

In this way, in the electronic dictionary 10 of the present embodiment, the word search can be performed normally even if the user does not understand whether the word to be searched by the user is used in a normal meaning or as a phrase. Just by doing this, you can effectively know the meaning and usage of a word or a phrase containing a word.
