The present invention semi-automatically constructs a band word dictionary that is manually constructed by automatically generating and presenting information of a band word dictionary which is constructed for selecting a band word of a terminology frequently appearing in a Korean patent document. It relates to a device and a method for increasing the efficiency of the.

First, terms used in the present specification are defined as follows.

In a Korean-language patent document, compound noun terminology is a collection of nouns that are united in the form of thorns, embryos, embryos, cells, and discoveries. It is called a noun, and if such a compound noun has a professional character that is not used well in general fields, it is called a compound noun terminology.

In the machine translation apparatus, the band word is the target language that has the same meaning as 'apple' and 'grape' in the Korean original text such as 'apple' and 'grape'.

The machine translation apparatus, which uses Korean as its original language, refers to a device that generates a band word of a target language as an input sentence for automatically translating Korean.

In the Korean patent document, the term “noun noun” refers to the nouns that constitute each unit of the compound noun terminology. The term is a single noun. When such a noun has a professional character that is not used in general fields, It is called a noun terminology.

The terminology in a Korean patent document refers to a term that is not registered in the analytical dictionary for the general field.

The selection of the bandword of a single noun refers to the selection of a bandword that can represent the meaning of a single noun constituting a compound noun.

In the machine translation apparatus, the source language refers to a target language to be read for translation, and in the case of Korean-English machine translation, Korean is called a source language.

In the machine translation apparatus, the target language refers to a target language for translation and generation, and in the case of Korean-English machine translation, English is a target language.

Next, the prior art will be described.

In the conventional machine translation apparatus, the selection of a band word uses a method of selecting a combination of band words for an input sentence using source language headwords registered in a band word dictionary and band word information corresponding thereto. In addition, in the case of selecting a compound noun band word, the compound noun was registered in the band word dictionary, and a predetermined word for the compound noun was selected in the input sentence.

In this case, in order to select a band word of a general noun or a compound noun, there must be an entry of a band word dictionary using the word as a keyword.

However, since the number of combinations of compound nouns is infinite, the bandword of the compound noun cannot depend only on the dictionary, and the bandword is calculated by combining the bandwords of the unit nouns constituting the compound noun.

Therefore, the construction of a single noun's bandword information becomes more important than the construction of a composite noun's bandword information.

In this case, when a machine translation is intended for a document that frequently uses a terminology such as a patent document, most of the single noun terminology is not registered in the existing bandword dictionary for general field, which degrades the performance of machine translation. It is a major factor. In addition, although the necessity of constructing the mononomous terminology terminology information is raised, in the case of a patent document in which various new terminologies continue to occur, a problem arises that a large amount of manual construction work requires enormous time and capital.

Accordingly, in order to solve the above problems, an efficient construction method for the bandword information of a single noun terminology and a method of using an existing construction knowledge instead of another additional knowledge are required.

The present invention has been proposed to solve the above problems and to meet the above requirements, and an apparatus for streamlining the work of constructing mononomous terminological bandword information for selecting a bandword of a terminology frequently appearing in a Korean patent document. The purpose is to provide a method.

Characteristic of the bandword dictionary construction device of the unregistered single noun patent terminology for the translation of patent documents according to the present invention for achieving the above object is to obtain the result of the morphological analysis using the target morphological analysis dictionary of the sentence of the input patent document Extracts a compound noun consisting of a noun sequence from the morpheme analyzer and the result of the morphological analysis as a nominal candidate, and is a single noun term that is not registered in the morphological analysis dictionary among the single noun terminologies constituting the extracted noun. Using the target terminology selection unit that selects a noun as a target for bandword selection, and using the extracted and selected compound noun jargon and the bandword, the general term bandword dictionary of the remaining single nouns except for the target single noun is inputted. Single noun band required for bandword selection by deletion A full noun band word selecting unit for obtaining information, a band word candidate selection determining unit for grasping the existence of remaining word terms deleted from the single noun band word selecting unit, and a band word remaining in the band word candidate selection determining unit A terminology presenting unit for presenting the terminology candidates automatically determined to the terminology bandword information builder, and an example sentence presentation unit for outputting a predetermined example in consideration of the failure of the bandword selection when there is no remaining bandword in the bandword candidate selection determination unit; have.

Preferably, the Korean morpheme analyzer is characterized in that the Korean sentence of the patent document is input in the form of a text string.

Preferably, the predetermined example output from the example presentation unit is characterized in that the front and rear words are cut by a specified number at a position where a single noun terminology occurs due to a band word failure.

Preferably, the presence or absence of the term bandword remaining in the candidate selection possible determination unit may be determined by referring to the number of remaining band words and position information.

Preferably, the target terminology selection unit is characterized in that the terminology appearing in the title and the terminology appearing in the text for the first time is selected as an object for selecting the band word by expressing an English band word corresponding thereto in parentheses.

Preferably, the unnecessary part deleted from the single noun band word selecting unit is characterized in that the band word is a single noun and affix information forming a compound noun terminology.

In order to achieve the above object, a feature of the bandword dictionary construction method of unregistered single noun patent terminology for translating a patent document according to the present invention is to (a) use information on a band noun and an affix of unit nouns forming a terminology in a patent document Extracting a compound noun type terminology target entry and a band word using the same; (b) selecting a band word candidate of an unregistered single noun terminology from the extracted compound noun terminology object entry and a band word, and (c) the band word. If there are no candidates, the method includes extracting and presenting example sentences of the terminology for manual construction.

Preferably, the step (a) comprises (a1) extracting an analysis result including a list of nouns, affixes, and unregistered words by morphologically analyzing the sentence of a patent document, and (a2) extracting the nouns, affixes, and unregistered words. Extracting the compound nouns formed by grouping the unit nouns and the parentheses by the parenthesis when the band word is present by the parenthesis after the enumeration, and (a3) extracting the title and the corresponding band word when the band word is present by the title notation of the patent document. It further comprises a step.

Preferably, the step (b) includes (b1) when there is an unregistered word among the unit nouns, removing the corresponding band word information by using band word information according to the part-of-speech information except for the unregistered word, and (b2) removing the remaining noun. And selecting a candidate candidate for the bandword of the target unregistered word using the number of the bandwords and the position information that appears.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following embodiment of the present invention, a terminology bandword dictionary construction support apparatus operating by inputting a patent document sentence including a compound noun jargon will be described as an example.

1 is a block diagram of a band word dictionary construction device of unregistered mononomous patent terminology for patent document translation according to the present invention.

As shown in FIG. 1, the apparatus for building a band word dictionary includes a morpheme analyzer 100, a target terminology selection unit 110, a single noun band word selection unit 120, a band word candidate selection determination unit 130, and a band word presentation unit. 140 and an example sentence presentation unit 170.

In this case, the morpheme analyzer 100 receives the Korean sentence of the patent document input in the form of a natural language in the form of a text string to obtain a morphological analysis result using a morphological analysis dictionary for the general field.

Subsequently, the target terminology selection unit 110 receives the result of the morphological analysis as an input and extracts a complex noun consisting of a noun sequence as a term for term candidate. At this time, due to the characteristics of the patent document, the terminology that appears in the title indicates the band word together, and the terminology that appears first in the text also extracts the corresponding word by focusing on the English term that corresponds to it in parentheses. do.

In addition, the target terminology selection unit 110 is not registered in the morpheme analysis dictionary 150 for a general field of a single noun jargon constituting a compound noun from the compound noun terminology thus extracted. We select a single noun analyzed as a target for bandword selection.

Then, the single noun band word selecting unit 120 receives the compound noun jargon and the band word extracted as such, and obtains a single noun band word information necessary for band word selection. ) To remove parts of the compound noun jargon that are not needed. In this case, the deleted band word may be used not only for a single noun constituting a compound noun terminology but also for affix information.

In addition, the band word candidate selectable determination unit 130 determines whether there is a term word word left after the deletion.

As a result of the grasping, when there are remaining band words with reference to the number of remaining band words and the location information, the band word candidates are automatically presented to the terminology band word information builder through the band word presentation unit 140.

Also, as a result of the grasping, if there is no remaining band word, the band word selection is considered to have failed. Example sentences made by the example sentence presentation unit 170 according to the failure of the band word is made by cutting the number of words before and after the specified number of noun terminology (for example, if you specify three by three words before and after the single noun Combine the three words from the list and print out a total of seven words.

Referring to the accompanying drawings, the operation of an apparatus for pre-registering a single word noun patent term for unregistered mononomous patent terminology for translation of a patent document configured as described above will be described in detail as follows.

FIG. 2 is a flowchart illustrating a method for building up a band word dictionary of unregistered single noun patent terminology for translating a patent document according to the present invention.

Referring to FIG. 2, first, a compound noun type terminology target entry and a band word are extracted using characteristics of a patent document in a Korean patent document (S10).

In other words, the sentence of the patent document is morphologically analyzed to extract an analysis result including a list of nouns, affixes, and unregistered words. In addition, when there is a band word by parentheses after the list of nouns, affixes, and unregistered words, a compound noun formed by grouping unit nouns and a band word by parentheses is extracted.

In addition, if there is a band word by title title of the patent document, the title and the band word are additionally extracted.

In this case, most of the terminologies generated in the patent document are marked with the bandword information to explain the contents, and in view of the fact that such bandword information can be used, there is no bandword information of a single noun terminology, By using the existing bandword dictionary by using the bandword information indicated in parallel with the term, a single noun terminology that requires bandword selection is extracted.

Subsequently, a band word candidate of an unregistered single noun terminology is selected by using the single term and affix band word information constituting the extracted terminology (S20).

That is, when there is an unregistered word among the unit nouns, the band word information is removed using the band word information according to the parts of speech information except for the unregistered word. Then, the candidate bandword candidate of the target unregistered word is selected using the number of the remaining remaining bandwords and the position information.

When the automatic selection of the band word candidate fails, that is, when there is no band word candidate, an example sentence of the terminology is extracted and presented for manual construction (S30).

As such, if there is no candidate for the bandword, it is possible to streamline the construction of the single-noun terminology bandword information by extracting and presenting example sentences in which a single noun terminology occurs.

3 is a view showing an embodiment showing a single noun terminology terminology determination by means of an apparatus and method for pre-registering monolingual patent terminology for translation of a patent document according to the present invention, wherein a concentrated stigmasterol solution? This is an illustration of a single noun jargon determinant called 'stiggsterol' for a noun jargon.

Referring to FIG. 3, first, the result of the Korean morpheme analyzer 100 for a patent document sentence is input to the target terminology selection unit 110 shown in FIG. 1, and the part-of-speech information is included in each word of the sentence. It is stuck.

Therefore, the "/ n" and "/ u" notation of "concentration", "stigmasterol", and "solution" in the original text of the patent document refer to nouns and unknowns, respectively. It occurs by (S200).

Subsequently, the target terminology selection unit 110 receives the original results, first finds the parts in which the nouns, unregistered words, and affixed results are connected to each other, and combines them into a compound noun to extract the compound noun terminology. do. At this time, the English parentheses that are predicted to correspond to the compound nouns are extracted together with the parenthesis.

Accordingly, since the target terminology selection result is obtained, "concentrated + stigmasterol + solution" is extracted as the corresponding compound noun jargon, and accordingly "a concentrated stigmasterol solution" is extracted together as an English band word candidate (S210).

In addition, the nouns that are not registered in the general field morpheme analysis dictionary 150 among the single nouns forming the compound noun terminology are determined as the words to be selected for the band word selection, and the "Stig Masterol" in the "concentrated stigmasterol solution" is the bandword information. Identify a single noun jargon without

Subsequently, in selecting the target mononomous terminology bandword, the bandword information of the words "concentration" and "solution" except for the target mononoun terminology "Stigmasterol" is referred to from the existing general term bandword dictionary 160, and " Terminology such as concentrated "and" solution "and the article" a "are removed (S220).

The remaining term band "stigmasterol" thus removed is a band term candidate of the target single noun terminology term "stigmasterol" and is presented to the terminology bandword dictionary builder by the terminology band word presentation (S230).

As described above, the preferred embodiment of the present invention has been disclosed through the detailed description and the drawings. The terms are used only for the purpose of describing the present invention and are not used to limit the scope of the present invention as defined in the meaning or claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the apparatus and method for constructing a bandword dictionary of unregistered single noun patent terminology for translation of a patent document according to the present invention using a compound noun jargon bandword information appearing in a patent document are not registered in advance. Automatically determine the bandword candidates for terminology and provide semi-autonomous terminology dictionary information for a single noun terminology by presenting examples of occurrences when a single noun bandword candidate is not extracted from a compound noun terminology bandword. The effect is to improve the efficiency of the large-capacity jargon dictionary construction.
