Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a language conversion system and a language conversion method for performing conversion between different languages such as natural languages such as English and Japanese, or program languages such as C and Java.

[0002]

2. Description of the Related Art In recent years, it has become possible to realize a language conversion system for converting a certain language into another language using an electronic computer. For example, as a language conversion system,
A machine translation system that converts (translates) a natural language such as English or Japanese from English to Japanese or from Japanese to English is used.

In a machine translation system, an input sentence to be translated and an output sentence after translation can be displayed at the same time, or an input sentence and an output sentence can be arbitrarily switched and displayed. FIG. 11 shows an example of a state in which an input sentence (English) and an output sentence (Japanese) are displayed.

[0004]

As described above, in a conventional language conversion system, an input sentence to be translated and an output sentence as a translation result can be displayed and confirmed. However, as shown in FIG. 11, since the output sentence is displayed as a series of sentences, it is necessary to determine which word (or idiom) of the input sentence is translated corresponding to which word of the output sentence or the like. Has become difficult.

[0005] For this reason, for example, when registering words, when it becomes difficult to know which words should be registered and how to register them, or when correcting the translation result, the words in the input sentence and the words in the output sentence are not registered. It is difficult to easily determine the correspondence, and the efficiency of the correction work has been reduced.

For example, in FIG. 11, "co" in an input sentence
Even if we wanted to know how "mpatible" was translated, the conventional language conversion system could not easily distinguish it from the output sentence.

The present invention has been made in view of the above-described circumstances, and is a language conversion system capable of easily determining the correspondence between a sentence in a language as a conversion source and a sentence in a language as a conversion result. It is an object to provide a system and a language conversion method.

[0008]

SUMMARY OF THE INVENTION The present invention provides a language conversion system for converting an input sentence in a first language into an output sentence in a second language. Input sentence separating means, conversion means for converting the output sentence in the second language for each range separated by the input sentence separating means, and an output sentence converted by the converting means An output sentence separating unit that separates by a predetermined range corresponding to a range of the input sentence separated by the separating unit; and an input sentence in the first language separated by the input sentence separating unit and the output sentence separating unit. Range display control means for displaying the separated output sentences in the second language by explicitly displaying the correspondence between the range in the input sentence and the range in the output sentence And wherein the door.

[0009] The range display control means may control the first display.
A range where there is no corresponding range between the range of the input sentence in the second language and the range of the output sentence in the second language is explicitly displayed to indicate that there is no corresponding range. .

A range designating means for designating an arbitrary range of the input sentence or the output sentence displayed by the range display control means, wherein the range display control means designates a range by the range designating means; When a range is specified in the input sentence, the contents of the range in the output sentence corresponding to this range are displayed at a specified position or near a specified range, and the range is specified in the output sentence. In this case, the content of the range in the input sentence corresponding to this range is displayed at a specific position or in the vicinity of the specified range.

A range designating means for designating an arbitrary range of the input sentence or the output sentence displayed by the range display control means, wherein the range display control means designates a range by the range designating means; When a range is specified in the input sentence, a range in the output sentence corresponding to this range is displayed with a specific attribute added thereto, and when a range is specified in the output sentence, A range in the input sentence corresponding to the range is added and displayed.

The machine translation unit 24 includes an input sentence separation unit 24a
, The input sentence is divided into an appropriate range serving as a unit of processing for machine translation of words, collocations, idioms, etc.
2 (input buffer 12b).

FIGS. 4 (a1) and 4 (b1) show examples (two types) of states in which input sentences are divided into predetermined ranges and stored in the input sentence storage section 22 (inputs shown in FIG. 11). Statements). FIG. 4 (a1) shows an example in which delimiter information for identifying each range is added and stored for each delimited range. FIG. 4 (b1) shows an example in which, for each word of the input sentence, common delimiter information is added to each word included in the delimited range and stored.
The input sentence is assumed to be stored in the input sentence storage unit 22 in any format.

The machine translation unit 24 performs machine translation on the input sentence stored in the input sentence storage unit 22 (step A).
3). The machine translation unit 24 generates a sentence in an intermediate language by sequentially performing, for example, morphological analysis, syntax analysis, and semantic analysis on an input sentence, and performs syntax generation, word string generation, and morpheme generation for the intermediate language. By doing so, a translation result (output sentence in the second language) is generated. It should be noted that the machine translation unit 24 can of course use another machine translation method.

The machine translation unit 24 includes an output sentence separation unit 24b
With respect to the output sentence that is the result of machine translation, the input sentence separating unit 24a
The output sentence storage unit 26 (output sentence buffer 12c) stores the output data in the output sentence storage unit 26 (output sentence buffer 12c) (step A4). In machine translation, a plurality of translation candidates (conversion candidates) may be obtained for one range to be translated. These conversion candidates are also stored in association with each other.

FIGS. 4 (a2) and (b2) show examples (two types) of states in which output sentences are divided into predetermined ranges and stored in the output sentence storage unit 26 (the output shown in FIG. 11). Statements). FIG. 4A2 shows an example in which, for each divided range, delimiter information for identifying each range is added and stored. FIG. 4 (b2) shows an example in which delimiter information is added and stored for each word of the output sentence. It is assumed that the output sentence is stored in the output sentence storage unit 26 in any format corresponding to the format in which the input sentence is stored in the input sentence storage unit 22.

Indicating the correspondence between the input sentence stored in the input sentence and the output sentence stored in the output sentence storage unit 26 (output sentence buffer 12c) is set in the correspondence table storage unit 28 (step A).
5).

FIG. 5 is a diagram for briefly explaining a method of setting the correspondence between the range of the input sentence and the range of the output sentence. First, it is assumed that an output sentence "3 piglets" as shown in FIG. 5A2 is generated for the example of the input sentence "Three child pigs." Shown in FIG. 5A1. As shown in FIGS. 5A1 and 5A2, for each of the input sentence and the output sentence, delimiter information is added to a unit in each sentence.

Further, in order to set the correspondence between the input sentence and the output sentence, for the input sentence, delimiter information in the output sentence indicating the corresponding unit in the output sentence is added as correspondence information for each unit, Similarly, for the output sentence, delimiter information in the input sentence indicating a corresponding unit in the input sentence is added as correspondence information for each unit.

For example, "chil" of the delimiter information 2 in the input sentence
"d" is added as the corresponding information the "child" delimiter information 4 which is the translation result of "child" in the output sentence, and "chil" in the input sentence is conversely added to the "child" of the delimiter information 4 in the output sentence.
The delimiter information 2 indicating “d” is added as the corresponding information.

It should be noted that the unit indicated by the delimiter information 2 or 3 in the output sentence does not have a corresponding one in the input sentence, and thus “φ” indicating that there is no corresponding one is added as corresponding information.

An example of an input sentence shown in FIG.
It is assumed that an output sentence “pig.” as shown in FIG. 5B2 has been generated for “e child pig.”. FIG. 5 (b1)
In the example shown in (b2), the delimiter information and the corresponding information are set for each unit of the input sentence and the output sentence as described above. However, as shown in FIG. “Φ” is set as the corresponding information of “The”.

The delimiter information and the correspondence information are stored in the input sentence storage unit 22 and the output sentence storage unit 26 in addition to the input sentence and the output sentence, respectively.
May logically represent the delimiter information and the corresponding information. The correspondence table storage unit 28 may store the delimiter information and the correspondence information separately from the data of the input unit and the output sentence.

The range display control unit 30 includes an input sentence display unit 30
a and the output sentence display sentence 30b, the input sentence storage unit 22
The input sentence stored in the output sentence storage unit 26 and the output sentence stored in the output sentence storage unit 26 are defined based on the correspondence relationship stored in the correspondence table storage unit 28 so as to clearly indicate a corresponding relationship for each appropriate range. Is displayed on the display device 14 (step A6).

Taking the input sentence and the output sentence shown in FIGS. 5 (a1) and 5 (a2) as an example, the input sentence display section 30a, as shown in FIG. The input sentence of the range and the corresponding information are managed, and the output sentence display sentence 30b manages the output sentence and the corresponding information of each range stored in the output sentence storage unit 26, as shown in FIG. 6B. .

FIG. 7 shows an example in which an input sentence and an output sentence are displayed so as to clearly indicate the correspondence between each appropriate range (division according to FIGS. 4 (a1) and (a2)). In the example shown in FIG. 7, each of the input sentence and the output sentence is underlined so as to indicate a delimited range, and the correspondence between the input sentence and the output sentence is clearly indicated by a numeral. ing.

For example, “provides” in the input sentence is assigned the numeral 2 and the same numeral 2 is assigned to indicate that “provide” in the output sentence corresponds. Also, in the input sentence, there is a "that" in which there is no corresponding range in the output sentence, but unlike other character strings, the correspondence between the underline indicating the delimited range and the specific range of the output sentence By not adding the number indicating, it is clearly indicated that there is no corresponding range.

The display form shown in FIG. 7 is an example, and in order to indicate the break positions of each range, in addition to underlining,
Use certain symbols, fonts, and character modifiers such as "/"
Alternatively, a specific color display may be performed. In addition, the correspondence between each range of the input sentence and the output sentence may be a specific symbol, font, character modification, or a specific color display in addition to the numeral.

In the above description, as shown in FIG. 7, each of the input sentence and the output sentence is displayed so as to clarify the correspondence in each specific range. In A6), it is possible to display a portion (range) corresponding to a range arbitrarily specified in the input sentence or the output sentence.

FIG. 8 is a flowchart showing a processing procedure for clearly displaying a portion (range) corresponding to an arbitrarily designated range. Hereinafter, description will be given according to the flowchart shown in FIG.

First, by operating the input device 16, the range specifying unit 32 inputs a specification indicating a specific range in an input sentence or an output sentence, and notifies the range display control unit 30. The default position may be a range located at the beginning of the input sentence.

When the input device 16 is a keyboard, the range designating section 32 may function in response to an operation on a cursor key, or keys specially assigned for range designating, for example, “shift” + “→”. (Cursor key) or the like. Alternatively, the designation may be made using a pointing device such as a mouse.

The target of range specification may be either an input sentence or an output sentence. When the range is specified in the input sentence, display control is performed so that the corresponding specific range in the output sentence is specified, and when the range is specified in the output sentence, the corresponding specific range in the input sentence is specified. . Here, a case where a range is specified in an input sentence will be described as an example.

The range display control unit 30 converts the output sentence corresponding to the range in the input sentence designated by the range designating unit 32 into
The determination is made based on the correspondence information in the correspondence table storage unit 28 (step B2).

Here, if the corresponding range is present in the output sentence, the range display control unit 30 adds the specific attribute to the corresponding range and displays the corresponding range in a form different from other ranges (step). B4).

In the same manner, if there is a portion corresponding to the designated range according to the range designation from the range designation section 32, the corresponding relationship is clearly displayed. FIG.
Shows an example in which a portion corresponding to the specified range is specified according to the range specification. In FIG. 9, in the input sentence and the output sentence, a specific range is indicated by a cursor (a range including a plurality of characters is displayed in reverse video and the size can be changed). Of course, any display form can be used as long as it can be distinguished from the others, such as underlining, change of font, change of display color, and the like.

First, as shown in FIG. 9 (a1), when the cursor which was initially located at "It" in the input sentence is moved to "provides", as shown in FIG. The “offer” of the range to be displayed is highlighted (cursor moved).

Next, as shown in FIG. 9 (a2), when the input sentence is moved to the next range "DOCVA102 and Tectron",
As shown in FIG. 9B2, “DOCVA102 and Tectron” in the corresponding range in the output sentence are highlighted (moved by the cursor).

Subsequently, as shown in FIG. 9A3, when the input sentence is moved to the next range "4444",
As shown in (b3), “4444” in the corresponding range in the output sentence is highlighted (moved by the cursor), and FIG.
When the input sentence is moved to the next range “compatible” as shown in 4), “compatible” in the corresponding range in the output sentence is highlighted (cursor) as shown in FIG. Moved).

Therefore, by designating a specific range of an input sentence or an output sentence only by an operation of designating a range (specifically, an operation of a cursor key of a keyboard), the corresponding range is moved by a cursor (reverse display) or the like. Can be clearly displayed by the display mode of (1).

In the input sentence, there is a "that" for which no corresponding range exists in the output sentence. If this range is specified (step B3), the range display control unit 3
0 displays a message notifying that the corresponding range does not exist in the output sentence, or deletes (or does not move) the cursor in the output sentence,
Specify that the range does not exist (Step B
5).

FIG. 10 shows an example of a display mode different from the example shown in FIG. In FIG. 10, a portion corresponding to the designated range is displayed by providing another window (display area) in accordance with the designated range.

First, as shown in FIG. 10 (a 1), when “provides” of the input sentence is specified, a window is provided near the position specified by this range, and as shown in FIG. 10 (b 1) Displays the character string "Provide" in the corresponding range in the output sentence.

Similarly, as shown in FIG. 10 (a2), when "compatible" of the input sentence is designated, a window is provided near the position designated by this range, and FIG.
As shown in 2), the character string “provide” in the corresponding range in the output sentence is displayed.

As shown in FIG. 10 (a 3), when “that” in which no corresponding range exists in the output sentence is designated in the input sentence, a window is provided near the position designated by this range, As shown in FIG. 10 (b3), a message “not supported” notifying that the corresponding range does not exist in the output sentence is displayed.

In FIG. 10, a window is provided in the vicinity of the range specified in the input sentence, and the character string in the corresponding range in the output sentence is displayed.
The position of the window does not necessarily have to be in the vicinity, but may be any position on the display screen.

In the case of the format shown in FIG. 10, a specific range of an input sentence or an output sentence is designated only by a range designation operation (specifically, an operation of a cursor key of a keyboard), so that a corresponding range is designated. It can be displayed explicitly in the window.

As described above, the input sentence to be converted and the output sentence as the conversion result are respectively divided into predetermined ranges, and the correspondence between the respective ranges is managed in the correspondence table storage unit 28. The range display control unit 30 enables display control to clearly show the correspondence between the ranges. By operating the input device 16, an arbitrary range in the input sentence or the output sentence can be designated by the range designation unit 32.
More input can be performed to display a corresponding range.

Therefore, when performing word registration, it is not lost which word should be registered and how to register it. Also, when correcting the translation result, the words in the input sentence and the words in the output sentence cannot be registered. Correspondence can be easily determined, and work efficiency of correction work can be improved.

In the above-described embodiment, since the language conversion for performing the machine translation for the input sentence is described as an example, the word, the collocation, and the translation unit of the machine translation are used.
Although the input sentence is divided into idioms and the like, the input sentence may be separated in an arbitrary range such as line by line or by sentence. Also, when performing another type of language conversion instead of natural language conversion, it is possible to divide by an arbitrary range according to the type of language conversion. In addition to language conversion for performing machine translation for natural languages, there is language conversion between C languages and programming languages such as Java.

The method described in the above-described embodiment includes, as programs that can be executed by a computer, for example, a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM,
It is also possible to write the data on a recording medium such as a DVD or a semiconductor memory and apply it to various devices, or to transmit it via a communication medium and apply it to various devices. A computer that realizes the present apparatus reads the program recorded on the recording medium, and executes the above-described processing by controlling the operation of the program.
