Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inflectional form output method in an electronic translator.

In recent years, electronic translators have been developed that, for example, input English and translate it into Japanese. However, this type of translator needs to store as many words as possible in its memory, which has limited capacity, so it is necessary to store regular forms of declensions, such as past tense of verbs and comparatives of adjectives. Things are not stored in memory. Therefore, it is not possible to know the inflectional forms of words that change regularly, such as the past tense.For example, is the past tense of "stop""stopped"?
There was a problem where I couldn't tell if it was stopped, or if it was changing irregularly but not being recorded.

This invention was made in view of the above circumstances,
The purpose of the present invention is to provide a method for outputting inflectional forms of words that undergo regular inflections without storing the inflectional forms in a memory.

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

FIG. 1 shows a plan view of an electronic translator employing the present invention. Various key groups 2 are arranged on the top surface of the main body 1 of the translator, 3 is a power on and all clear key, 4 is a power off key, 5 is a key for instructing Japanese input mode, and 6 is a key for instructing English input mode. 7 is a key for instructing translation of an input word or sentence, and 8 is a single character correction key. Also,
9 to 15 are conversion keys for finding the inflectional form of the input word, 9 is a past tense key, 10 is a past participle key, 11 is a plural key, 12 is a comparative key, and 13 is a superlative key. , 14 is the progressive key, 15
is the third person singular present tense key. On the other hand, the remaining keys are keys for inputting English or Japanese. After operating the above Japanese key 5, the kana written on each key is input, and after operating the English key 6, each key is input. The alpha alphabet written in is input. Note that 16 is a display section, which is composed of, for example, a 20-digit 5.times.7 liquid crystal dot matrix display device.

Next, the circuit configuration of this embodiment will be explained with reference to FIG. In the figure, reference numeral 21 denotes a key input unit having the above-mentioned keys, and words input from this key input unit 21 are input to an input register 22. 23 is a search circuit,
This circuit searches the dictionary memory 24 for the word input to the input register 22. The dictionary memory 24 has a first area 24, as shown in FIG.
It is divided into area A and a second area 24B. The first area 24A stores English words in alphabetical order, as shown in detail in FIG. 3b.
Each word is attached with a part-of-speech flag indicating its part of speech, an inflection flag indicating an inflection pattern, and address data indicating the address where the Japanese word to be translated is stored. However, it goes without saying that words that do not undergo inflection, such as prepositions and conjunctions, are not provided with inflection flags. Each of the above-mentioned inflection flags is composed of a predetermined code, and is decoded by a discriminating circuit, which will be described later. Furthermore, for words that change irregularly, instead of the inflection flag, address data indicating the address where the word with the inflection form is stored is stored. For example, in the area of the past tense flag for "HAVE", an address in the dictionary memory 24 where the word "HAD" is stored is written. Note that (UC) in the "plural" area of the inflection flag means an uncountable noun, and the plural and original forms are the same. On the other hand, in the second area 24B, Japanese words are arranged in alphabetical order, and address data indicating the address where the English word to be translated is stored is added to each word.

The search circuit 23 is supplied with an English→Japanese/Japanese→English mode signal from the key input unit 21, an operation signal for the translation key 7, and operation signals for various conversion keys 9 to 15. Depending on the operation signal, English →
Depending on whether the mode is Japanese mode or Japanese→English mode, English or Japanese words in the dictionary memory 24 are searched in the order in which they are stored, matched with the words in the input register 22, and the matched words are searched. With reference to the translation address, a Japanese or English word to be translated is read out and output to the output register 25. Also,
By operation signals of conversion keys 9 to 15, as above,
After searching the dictionary memory 24 for the word in the input register 22, the contents of the word's part of speech flag and inflection flag are sent to the discrimination circuit 26. This discrimination circuit 26 inputs the conversion key 9 from the key input section 21.
The above-mentioned flags are decoded based on the operation signals of ~15, the inflection pattern of the word is determined, and the corresponding address of the deformed part data table 27 that stores the deformed part data of words that undergo regular inflections is determined. This is a circuit for specifying and reading. The configuration of the deformed portion data table 27 is shown in FIG. Also,
If it is determined that the change is irregular, a determination signal is sent to the search circuit 23. The modified portion data read from the modified portion data table 27 is supplied to the synthesis circuit 28. Also, this synthesis circuit 28
is supplied with the discrimination signal from the discrimination circuit 26 and the input word from the search circuit 23, synthesizes the input word and the transformation part data to create an inflection form, and outputs the synthesized inflection form to the register 25. Send to. The contents of this output register 25 are displayed on the display section 16.
will be displayed.

Note that 29 is a control unit that controls the entire system. Various timing signals, control signals, etc. output from the control section 29 are omitted for clarity of the drawing.

Next, the operation of this embodiment will be explained.

First, the English mode input key 6 of the key input section 21
When operated, the mode changes from English to Japanese, and this mode information is given to the search circuit 23. Suppose that, for example, the word "STUDY" is input using the alphanumeric keys. This word is written to input register 22. Next, when the translation key 7 is operated, the search circuit 23 searches the dictionary memory 24, detects "STUDY", reads out the translated word "BENKIYOSURU" to the output register 25, and displays it on the display section 16, a so-called translation process. However, if you want to find an inflectional form, for example, the past tense, operate the past tense key 9. When the past tense key 9 is operated, the operation signal is supplied to the search circuit 23,
The search circuit 23 starts a search operation on the dictionary memory 24. That is, first, the address of the first word in the dictionary memory 24 is designated, the word is read into the buffer 1 (not shown) in the search circuit 23, and compared with the word in the input register 22. If there is no match, the address for the dictionary memory 24 is incremented and the next word is read. At the time of matching, the buffer in the search circuit 23 contains:
The word "STUDY", part of speech flag, inflection flag, and translation address data are written. The part of speech flag and inflection flag are then sent to the discrimination circuit 26. This discrimination circuit 26
is supplied with an operation signal for the past tense key 9 from the key input section 21, and therefore refers to the past tense flag among the supplied inflection flags. Then, y
A pattern of inflection in which "i" is changed and "ed" is added is determined, and the determined signal is sent to the transformation part data table 27. This discrimination signal is the address data of the modified part data table, and the modified part data "IED" in the modified part data table 27 is selected and sent to the synthesis circuit 28. In the synthesis circuit 28, the word "STUDY" stored in the buffer in the search circuit 23 is read into a register (not shown) in the synthesis circuit 28, the character "Y" in the lowest digit is cleared, and the word "STUDY" is transformed into the ending of the word. ``IED'' read from the partial data table 27 is written, and the synthesized ``STUDIED'' is output to the output register 25.

With the above operations, the process of synthesizing the past tense "STUDIED" for the input word "STUDY" is completed.

Other transformation processes are basically the same and will not be explained here, but for cases where the endings of the original form are overlapped, such as "STOPPED", the search circuit 23
It is necessary to read out one character of the least significant digit of the word written in the register in the synthesis circuit 28 from 1 to the buffer in the synthesis circuit 28, and then write it after the least significant digit of the register.

In the above embodiment, an inflection flag is provided along with each word in the dictionary memory to determine the inflection pattern. However, the present invention is not limited to this, and the ending of the word can be directly determined, for example, in the case of past tense, If the ending of the word is "e", add only "d", consonant +
If it is "y", clear the final consonant and say "ied"
It is also possible to perform processing such as adding .

In addition, in the above embodiment, when the original form is input and the conversion key is operated, the corresponding inflectional form is output, but the invention is not limited to this, and the inflectional form is necessary during the translation process of the sentence. It is also possible to automatically synthesize inflectional forms when

Furthermore, although the above embodiments have been explained using English as an example, it goes without saying that the invention can also be applied to other Japanese languages.

In addition, if you prepare declension forms for the translated word, it becomes possible to translate past tense, plural, progressive, etc.

In addition, electronic translators generally have a function that searches for and outputs the closest word when the input word is not recorded in the dictionary memory, but in this case, the inflectional form of the word found is If the words are synthesized and matched with the input word, it becomes possible to input the inflectional form and translate it.

Furthermore, in order to apply it to a learning machine, the learner inputs the original form and the inflected word form, and the machine compares the inputted inflected word form with the inflected word form synthesized from the original form input, and determines whether the answer is correct or incorrect. It is only necessary to configure it so that it is displayed.

In short, various application examples are possible without departing from the gist of the present invention.

As explained above, according to the present invention, for words with regular inflections, a plurality of inflection flags indicating inflection patterns are stored in the dictionary memory, and the input word and the type of conversion key (past tense key) are stored in the dictionary memory. 9, past participle key 10, etc.), the inflection flag is referred to and the corresponding inflection form is output, so the conversion key for the input word can be output without storing the inflection form itself in the dictionary memory. It is very effective when studying inflections because it allows you to know the inflectional forms according to the types of words, and it has the effect of essentially doubling the number of recorded words.
