Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generates Japanese phonetic transcriptions of Roman letters and katakana from phonetic symbols of foreign language dictionaries, and uses the phonetic transcriptions as natural Japanese (hereinafter,
(It may be simply referred to as notation) or a phonetic notation fluctuation (notation variation) as a shortened phonetic notation as a search key that is unified into a prescribed phonetic notation together with the foreign language dictionary data (original data) By registering as a database, it is possible to search the foreign language dictionary database from the search key of the Japanese phonetic expression entered without paying attention to the rules of the Japanese phonetic expression of the foreign language. Related to searching electronic dictionaries.

[0002]

2. Description of the Related Art Due to the progress of internationalization, the proportion of foreign words in Japanese, which is a Japanese foreign language, so-called "Katakana", especially "Katakana English", is increasing. Most of these foreign words are used as phonetic transcriptions whose pronunciations are written in katakana. Most of the pronunciations are expressed as in line with the pronunciation of Japanese, but the Katakana expression and the Roman expression corresponding to Katakana are also mixed. In addition, many are used for meanings different from the meanings of the words in the original language (foreign language). Conventionally, for example, JP-A-61-100864, JP-A-5
As disclosed in Japanese Laid-Open Publication No. 7-161970, a correspondence table of foreign language katakana notation or katakana equivalent romanization and the spelling of the foreign language is prepared in advance, and foreign words are input to katakana notation or katakana equivalent romanization. It is known to display the spelling of a word and perform a dictionary search based on the spelling.

[0003]

It is enormous to create a correspondence table of foreign language katakana notation or romanized notation equivalent to katakana and spelling of the foreign language for all foreign language words as in the above-mentioned conventional technique. It requires a lot of work, errors are inevitable, it cannot be said that it is efficient, and it is not easy to revise it according to the daily increase of Katakana.

On the other hand, the IPA notation (International Phone) is used as a phonetic notation that represents the pronunciation of a foreign language.
There is a unified phonetic transcription such as tic Alphabet), but this is difficult for Japanese people to understand, and it is much more labor to input the new pronunciation in correspondence with the phonetic symbols of the existing dictionary. Need.

Further, even if the correspondence table as disclosed in the above publication is created and registered as an electronic dictionary, the katakana notation has fluctuations in notation, that is, variations in katakana expression,
There is inconsistency, and it is difficult to create and register a correspondence table for unifying such fluctuations in notation for all words. For example, even if we take the word "gesture," the katakana notation is "gesture,""gesture,""gesture." ． Such,
You can see a lot of vague notations (the fluctuation of the above notation). It is impossible to register this for all words.

As described above, when a foreign language is written in Japanese phonetics, the notation spanning syllables is different.
For details, since there is phonological fluctuation), it is difficult to set the search key due to the ambiguity of the above-mentioned notation in Japanese. There was a problem in simply using katakana notation without knowing the notation rules).

An object of the present invention is to search for an original foreign language from a Japanese phonetic transcription of a foreign language, such as Katakana, without paying attention to the standard Japanese phonetic transcription. It is an object of the present invention to provide a method and apparatus for searching an electronic dictionary so that a search key can be entered with a favorite notation.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a foreign language electronic dictionary generation / retrieval device according to the present invention. 1 is a phonetic transcription generation unit, 2 is a notation correction unit, 3 is a storage unit, 4 is a search key input unit, Reference numeral 5 is a search result output means.

In the figure, the phonetic transcription generation unit 1 extracts phonetic symbols from the original data of the foreign language dictionary and makes katakana or romaji phonetic symbols based on these phonetic symbols. The generated phonetic transcription is corrected by the transcription correction unit 2 according to the spelling (spelling) so that the transcription becomes natural as Japanese (easy to pronounce for Japanese).

The corrected phonetic transcription is registered in the storage unit 3 together with the original data of the foreign language dictionary which is the original dictionary. The storage unit 3 is provided with at least a phonetic transcription storage area (Japanese phonetic transcription storage area) for storing the phonetic transcription as a search key and a word record storage area for storing the original data as a record for each word. When the user inputs a phonetic symbol (phonetic notation) of a foreign language in Katakana or Roman letters from the search key input unit 4, the search result is output to the search result output unit 5.

FIG. 2 is a block diagram for explaining the configuration of the Japanese-English katakana search device according to the first embodiment of the present invention.

In the figure, the phonetic transcription generation unit 1 includes an original dictionary (English-Japanese dictionary) 21 in the form of MT and a dictionary reading means 22.
And katakana notation input means 23. The dictionary reading means 22 has a function of structuring the dictionary data of the original dictionary 21 into a form that can be processed by a computer, and the katakana notation input means 23 is a Japanese-based table based on phonetic symbols obtained from the original dictionary data. It has a function to generate phonetic notation, and here it generates katakana notation.

Next, the operation of the configuration of the embodiment shown in FIG. 2 will be described. First, a dictionary database is created based on the data of the English-Japanese dictionary which is the original dictionary, and this is registered in the storage means 3. Generally, the original dictionary 21 is supplied as electronic data in the form of MT. Read this into the dictionary reading means 22,
A computer-processed structured text is created according to a predetermined rule.

FIG. 3 is an explanatory view of an example of structured text, showing a record for one word constituting a dictionary, and 21 is a record of a dictionary item (attribute) for the word "list", which is a headword. A word "list",
Its importance ** (for example, those that should be learned in high school are marked with *, those that should be learned in middle school are marked with **), phonetic symbols [list], and part-of-speech items,
Furthermore, records 22-1, 22 decomposed into parts of speech items
-2 generates a word record structured in a tree structure or the like. In the example of the figure, the word "list" is used as a headword, and the importance **, pronunciation [list], and noun as a part of speech (meaning: name list, example: Her nameis ...,
Phrasebook: make a list of. ． , ...) and transitive verbs (meaning: represent, example: ...) are generated as structured data as shown.

The pronunciation item is extracted from the structured data, and its phonetic symbol ([list] in the example of FIG. 3).
To the katakana notation input means 23. The katakana notation input means 23 generates katakana notation from the given phonetic symbols. The generation of the katakana notation can be executed by the same algorithm as the Roman character → kana conversion used in a known Japanese word processor or the like.

The katakana notation (kana notation) generated by the katakana notation input means 23 is supplied to the correction means 24 to be corrected to the Japanese pronunciation notation. Japanese is based on the fact that each syllable ends with a vowel, which is very different from the notation in foreign languages such as English. To solve this problem, the following corrections are made to English phonetic symbols.

FIG. 4 is an explanatory view showing the correspondence of the correction information added to the English phonetic symbols, and the symbols b, d ,. ． k,
1, p ,. ． , Respectively. ． Ku, Le,
,. ． Is added. For example, the word deskk
The phonetic symbol [desk] is [s] [k], followed by [u] and [des]
uku], and as this katakana phonetic notation [desk]
To generate.

However, a warm vowel [∂] is obtained only by phonetic symbols.
The syllable notation, etc., cannot be determined. Therefore, it is necessary to give the correction means 24 spelling and syllable information (“-”) obtained from the katakana notation and the dictionary reading means to correct the pronunciation.

FIG. 5 is an explanatory diagram of a correction correspondence table for warm vowels, where [ca, ke] is [month] and [cau, co].
Is [ko] ,. ． ． ． Correspond as follows. For example,
The first half syllable of con-cern [k∂ns∂: rn]
The con 'corresponds to [k∂n], so [con], and the second half syllable'cern' corresponds to [s∂: rn] is [sarn]. Determine the pronunciation of the vowel vowel.

FIG. 6 is an explanatory view of the contents of the corrected katakana phonetic transcription record and word record stored in the storage means, and the word record 62 is stored using the katakana phonetic transcription 61 as a search key.

FIG. 7 is an explanatory diagram of a user view showing an output example of searching the English-Japanese dictionary database generated as described above and stored in the storage means. The search key input unit 4 can be composed of an OCR reading device 26 and a voice input means 27 in addition to the input means 28 consisting of a normal keyboard / mouse, and the search key input from either of them is [English]. When input, the search key [English] is displayed in the input view 72 of the view 71, and the search result "E" is displayed based on this search key.
The English word “nglish” and its related items (phonetic symbol, part of speech, meaning, ...) Are displayed in the output view 73.

As the output means for outputting the retrieval result, in addition to the visual display by the user view of the display means as described above, the hard copy means 30 for directly printing out on paper or the voice output means for outputting by voice. It can also be configured with 31 or the like.

The foreign language dictionary such as the English-Japanese dictionary generated as described above is not limited to the usage as described in this embodiment, but can be used as an original foreign language dictionary, that is, can be searched from a headword. Needless to say. In this case, if the word input from the search input unit 4 in FIG. 2 is an English character, the entry word shown in FIG. 6 is used as a key for searching.

At this time, by outputting the katakana phonetic transcription record 61 in addition to the word record 62, the learning effect is increased when a foreigner uses this dictionary for learning Japanese. There is also. With the recent internationalization, the number of foreigners living in Japan is increasing. Katakana is one of the major obstacles for foreigners to learn Japanese.

The Katakana language is often written in a pronunciation that is far from the original due to the pronunciation of the Japanese, and is often created based on the feeling of the fashionable side. Mostly confusing. The present invention is also an effective means for understanding such Katakana.

FIG. 8 is an explanatory diagram of a user view for explaining a usage pattern that contributes to understanding of Katakana language. When the user is assumed to be a foreigner and the entry word “Japanease” is input from the search key input unit 4. , The input search key is displayed in the input view 82 of the user view 81,
The search result is displayed in the output view 83.

On the output view, the Japanese katakana notation corresponding to the input English headword is output. With this katakana notation, foreigners can learn Japanese pronunciation in addition to the usual Japanese meaning. By using this, when writing a Japanese sentence, it is possible to create a Japanese sentence with Katakana language, which can be expected to improve the learning effect.

As described above, according to this embodiment, it is possible to automatically obtain Roman or Katakana notation from phonetic symbols that are generally difficult to understand, and to use a foreign language dictionary through Japanese phonetic notation. it can.

Next, generation of a foreign language electronic dictionary according to the present invention
Another embodiment of the search device will be described. FIG. 9 is a block diagram for explaining the configuration of the second embodiment in which the present invention is applied to an English-Japanese katakana search system. 1 is a phonetic notation generation unit, 2 is a notation correction unit, 3 is a storage unit, and 4 is a search. A key input unit 5 is a search result output unit. Then, as in the above embodiment, the phonetic transcription generation unit 1 extracts phonetic symbols from the original data of the foreign language dictionary and generates phonetic symbols in katakana or romaji based on the phonetic symbols. Phonetic transcription generation unit 1 is M
It comprises an original dictionary (English-Japanese dictionary) 21 in the form of T, a dictionary reading means 22 and a katakana notation input means 23. That is, the dictionary reading means 22 has a function of structuring the dictionary data of the original dictionary 21 in a form that can be processed by a computer, and the katakana notation input means 23 produces phonetic sounds based on phonetic symbols obtained from the original dictionary data. It has a function of generating symbols (phonetic notation), and here, katakana notation is generated.

As for the structuring of the dictionary data, as described in detail with reference to FIG. 3, a structured text that can be processed by a computer is created according to a predetermined rule.

Dictionary data composed of structured word records as shown in FIG. 3 is stored in the storage means 25 constituting the storage unit 3. On the other hand, the katakana notation input means 23 of the phonetic notation generation unit 1 extracts a phonetic symbol item of dictionary data, generates katakana notation from this phonetic symbol, and forms the generated katakana notation in the notation correction unit 2. It is given to the phonetic notation shortening means 241 to perform a notation shortening process for correcting the fluctuation of the notation.

The katakana notation generated from the phonetic symbols of the English-Japanese dictionary, which is the original dictionary, is often different from the Japanese notation, and there are various notations (jitters) in the katakana notation as Japanese. Registering such a variety of notations in the dictionary database consumes a large amount of storage work as well as enormous amount of generation work.
It is not efficient in terms of the entire system, such as reducing the search speed. In this embodiment of the invention,
In order to solve the above-mentioned fluctuation of the notation, processing for uniquely shortening this fluctuation, that is, processing for making a unified shortened notation is performed.

Hereinafter, the shortening algorithm in this katakana notation shortening means will be described with reference to FIGS. 10 to 13 (note that the retrieval key shortening algorithm at the time of retrieval, which will be described later, is also the same).

FIG. 10 is a flow chart for explaining the Katakana reduction algorithm, and FIG. 11 is a consonant conversion table (C
T), FIG. 12 is an explanatory diagram of a double vowel table (DT), and FIG. 13 is an explanatory diagram of a one-character substitution table (OT).

First, after the buffer is cleared and variables are initialized (step 1, hereinafter referred to as "S1"), the katakana notation input means 23 outputs a sound from the katakana character string input from the dictionary reading means 22. A data stream RS for inputting the notation shortening means (a data transfer structure for transferring the katakana notation generated from phonetic symbols, hereinafter simply referred to as stream RS) is generated (S2). At the same time, an output data stream WS (a data transfer structure for transferring the shortened katakana notation, hereinafter simply referred to as stream WS) for storing the shortened result in the storage means 25 is also generated (S3). .

The phonetic transcription shortening means 241 is a stream RS.
The first character is read and stored in the buffer (S4), it is determined whether the character is the last position of the stream RS input (S5), and if it is the last position (YE in S5).
S) Branch to S12. If it is not the last character, that is, if there are still characters in the katakana character string (NO in S5), the second character is read into the buffer BF (S).
6).

When the second character is read, the contents of the buffer BF are replaced by the consonant table DT of FIG. 11, and this is written in the buffer BF (S7). Consonant table C
When there is no replacement notation corresponding to T and the replacement cannot be performed (NO in S8), the double vowel table D in FIG.
The contents of the buffer BF are replaced by T (S9), and the replaced contents are written in the buffer BF. If the consonant table CT can be replaced (YES in S8), S14
Branch to.

Here, the consonant table CT and the double vowel table DT are provided separately in order to uniquely shorten them by prioritizing the consonant → vowel notation during the shortening process. Further, by processing every two characters, it is possible to absorb the fluctuation of the notation spanning syllables peculiar to Katakana described later. The "shortening" here is an intermediate expression for absorbing the fluctuation, and as is clear from the table of FIG. 11, the number of characters may not change even after the replacement process.

When the contents of the buffer BF are replaced using the double vowel table of FIG. 12 (YE in S10).
S) and S14. If the contents of the buffer BF have not been replaced, that is, if the contents have not been shortened (NO in S10), the second character of the buffer BF is cleared and erased (S11). That is, only one character written in ST4 exists in the buffer BF.

Next, the one character written in the buffer BF is subjected to the replacement process with reference to the one-character replacement table OT shown in FIG. 13 (S12), and the replacement result is stored in the buffer BF. At this stage, the characters that have not been replaced are still written.

In this state, since the position of the stream RS is advanced by one extra position, the position of the stream RS is returned by one (S13), and the contents of the buffer BF are written in the stream WS (S14).

After writing the contents to the stream WS, the buffer BF is cleared (S15) and it is judged whether the position of the stream RS is the last position (S16). If it is not the last position (NO in S16). ) Returning to S4, the same shortening process as above is continued. When it is determined that the stream is the last one, that is, when the reading of the stream RS is completed (YES in S16), the shortening process is finished, and the contents of the stream WS are output as a shortened character string to the search key storage area of the storage means. (S17), the process ends.

Hereinafter, a concrete example of this shortening process will be described as "gest".
"ure" will be described as an example. The word "gestur
When a "gesture" is given as the katakana notation for the pronunciation of "e", first, the first character "ji" and the second character "e" from the stream RS of the input character string are phonetic notation shortening means 2.
It is read into the buffer BF 41. The content of the buffer BF becomes "Je".

The content "Je" of this buffer BF is shown in FIG.
After being written in the buffer BF after being replaced with "Ze" by referring to the consonant table CT shown in (i.e., shortened to the one-character phonetic notation), the contents of this buffer BF are the stream of the output character string. The buffer BF is cleared as it is written to WS.

Since the katakana phonetic notation generated from the phonetic symbol of the word of the stream RS still has "... STUAR" (that is, the input position of the stream RS is not the last), the buffer BF has "STUDIO". ”
Although "chi" is read, this "suchi" is not written in either the consonant table or the double vowel table, so the replacement process is not performed. Therefore, as described above, the second character “H” read in the buffer BF is erased, and the “S” remains, which is not a replacement target even in the one-character table in FIG. 13 and is therefore written in the stream WS as it is. Be done.

After clearing the buffer BF, "HI" and "CHA" read next from the stream RS are similarly written to the stream WS. And at the end "one"
However, since this is the last position of the katakana phonetic notation of the stream RS, it is directly replaced with the one-character table, but since it is'deleted 'in this table, the buffer BF becomes empty. , Nothing is written to the stream WS, and the shortening process ends.

As a result, the content of the stream WS is "gesture", which is output to the storage means as a shortened character string in katakana notation of the pronunciation of the word "gesture". In this way, the generated short notation is registered in the storage unit 25 together with the structured word record generated by the dictionary reading unit 22 of FIG. 9 using the generated short notation as a search key. By repeating this for all the words in the original dictionary, a database of the Katakana search English-Japanese electronic dictionary is constructed.

FIG. 14 is a schematic view of the view of the display means constituting the search result output section, and executes the dictionary search using the Katakana search English-Japanese electronic dictionary database generated and constructed as described above. If the user first
The word to be searched is input in katakana notation from the keyboard 28 constituting the search key input section 4 of FIG. 9 (note that the search key input section 4 and the search result output section 5 are various means as shown in FIG. 2). Can be configured with).

The inputted search key is converted into the shorthand notation by the phonetic notation shortening unit 241 of the notation correcting unit 2 as in the case of generating the database, and this shorthand notation is registered in the storage unit 25 as the search key. Search the database you are using. Since the abbreviated notation of this search key is also the same as the abbreviation used when registering the database, the user can enter it in their favorite katakana notation, and the standard katakana notation Lulu (notation) and the above There is no need to be aware of the shortening algorithm.

When the user tries to search for "gesture", "gesture", "gesture", or "gesture" depends on the user or the feeling at that time.
Enter the search key in various katakana notation such as “gesture”, “gesture”, and so on. That is, there is a fluctuation in the notation of the search key to be input. However, the fluctuation of this notation is not limited to the case of the same "gesture" as when registering the database, but in all other cases, it is uniquely converted to the short notation "gesture", so "gesture" is stored in the storage means. As a search key, the word record of "gesture" is searched.

In FIG. 14, the search key “gesture” input by the user is displayed in the input view 132 of the user view 131, and the word record of the search result is displayed in the output view 133 and presented to the user.

The foreign language dictionary such as the English-Japanese dictionary generated as described above is not limited to the use as described in this embodiment, but is used as an original foreign language dictionary as in the first embodiment, that is, It goes without saying that it is possible to search by entry word. Also, by outputting standard katakana notation (“gesture”) in addition to the word record in the search results, the learning effect will be greater when foreigners use this dictionary for learning Japanese. There is also a utility. As mentioned above, Katakana is a phonetic transcription that is far from the original due to the pronunciation of the Japanese, and it is often created by the Japanese arbitrarily, which causes confusion for foreigners. Often there is. The present invention is an effective means for foreigners to understand such Katakana language.

FIG. 15 is an explanatory diagram of a user view for explaining a usage pattern that contributes to the understanding of Katakana language. Assuming that the user is a foreigner, the self-style katakana notation “gesture” is input from the search key input unit 4. When input, the input search key is displayed in the input view 142 of the view 141, and the search result is displayed in the output view 143.

As a result, it is possible to know the standard katakana notation of the English word without knowing it,
The learning effect of Japanese is greatly improved for foreigners (and for Japanese as well).

As described above, according to the present embodiment, when manually inputting the katakana notation as a search key, it is possible to perform a word search using the katakana notation of the own style without knowing the rules for katakana notation, and the abbreviation is used as the search key. Therefore, the capacity of the storage means is small, and high-speed search is possible.

[0061]

As described above, a phonetic transcription of Roman letters or katakana is automatically obtained from phonetic symbols that are generally difficult to understand, and this is used as a search key in a foreign language dictionary through Japanese phonetic transcription. It becomes possible to handle, and even people who are not good at foreign languages can search by pronunciation (phonetic notation). Also, when inputting phonetic notation such as katakana as a search key, without considering the standard notation rules,
It is possible to input in the notation preferred by the user and improve the Japanese learning effect for those who are not familiar with foreign languages.
