The present invention relates to an apparatus and method for constructing a translation dictionary, and more particularly, to an apparatus and method for constructing a patent translation dictionary based on a large-capacity monolingual patent document.

Techniques for building a translation dictionary include a method of manually attaching a band language of a target language (or target language) manually with respect to a jargon of a source language (or source language). This is, for example, a method of performing machine translation on a starting language in a translation system using a network, and then manually attaching (translating) the band language of the target language to the terminology of the starting language.

Further, a technique of extracting unregistered words and grasping relationship information between the unregistered words may be cited as an example. For example, the information retrieval system extracts unregistered words in relation to search term expansion, attaches conceptual information to the unregistered words, analyzes the conceptual information, and manually registers them in a translation dictionary (eg, a compound noun). In the case of ambiguity removal).

These methods ultimately constitute a critical factor for human intervention in order to build a translation dictionary, and this human intervention has a problem in that an excessive amount of time and effort is spent in constructing a large-capacity translation dictionary.

Accordingly, it is an object of the present invention to provide an apparatus and method for constructing a large volume of patent translation dictionaries that minimize human intervention.

As shown in FIG. 1, the apparatus includes a term reconstruction unit 200 for constructing an extended DB for general translation dictionary (hereinafter referred to as DB for extended dictionary) based on existing terminology. Semi-automatically translates the term processing unit 300 to add unregistered terminology not registered in the extended dictionary DB, and the patent translation dictionary DB 500 according to the present invention by translating into a band language suitable for the patent field based on the extended dictionary DB. Band word specialization unit 400 to be built.

In addition, the apparatus is a DB 100 for general translation dictionary, instrument axis term input unit 600 for receiving existing technical terms, and starting language patents to build a DB for patent translation dictionary 500 according to the present invention The apparatus further includes a starting language input unit 700 for receiving a document and a target language input unit 800 for receiving a target language patent document.

The operation of the patent translation dictionary construction device according to the embodiment of the present invention configured as described above will be briefly described.

First, the term reconstruction unit 200 is a form that can be recorded in the patent translation dictionary DB (500) based on the general translation dictionary DB (100) by receiving the existing terminology established in the instrument axis term input unit (600) Change the format to build the extended dictionary DB (900).

Subsequently, the term processing unit 300 receives a specific departure language patent document from the departure language input unit 700 and extracts unregistered terminology not registered in the newly constructed extended dictionary DB 900 from this patent document. In addition, the term processing unit 300 classifies the single word entry among the extracted unregistered terminology and manually attaches the single word entry without the band word attached thereto, and adds the entry to the extended dictionary DB 900.

Subsequently, the band language specialization unit 400 receives a target language patent document from the target language input unit 800 and selects a band word suitable for the patent field from a plurality of band words in the extended dictionary DB 900 in which unregistered terminology is added. In addition, the compound language is translated into a specialized monolingual language to construct a DB 500 for a patent translation dictionary.

Hereinafter, an apparatus for constructing a DB for patent translation dictionary according to the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 2 is a detailed block diagram illustrating the term reconstruction unit of FIG. 1.

As shown in FIG. 2, the term reconstruction unit 200 is a term comparison unit 210 that compares general terms of the DB 100 for general translation dictionary and headwords and band words of existing terminology, and term comparison. The term conversion unit 220 converts the existing terminology inputted according to the comparison result of the unit 210 into the format of the DB 100 for general translation dictionary, and the DB for general translation dictionary The term removing unit 230 which deletes or adds to the DB 100 according to the existence of the entry in the DB 100, and separates the added terminology into a single word compound and a compound word entry, and separately stores the extended dictionary DB 900. Includes a terminology processor 240 to add to.

In addition, the term reconstruction unit 200 further includes a general translation dictionary DB 100 referred to the term comparison unit 210, and an instrument axis term input unit 600 for receiving existing technical terms.

The term reconstruction unit 200 configured as described above will be described in more detail.

The term comparison unit 210 receives a conventionally constructed terminology and compares the terminology and band language of the terminology with the language recorded in the DB 100 for a general translation dictionary. As a result of the comparison, if the heading language of the DB 100 and the heading language of the terminology are the same, or if the heading language of the DB 100 and the head language of the terminology are the same, the term comparison unit 210 converts the term. The terminology is transferred to the unit 220, and other than that, the term is simply returned without passing the terminology to the term conversion unit 220.

The term converter 220 converts the transferred terminology into a format suitable for the DB 100 for a general translation dictionary. The term removing unit 230 adds a counterpart of the term to the corresponding heading of the DB 100 when the converted term is an entry existing in the DB 100 for a general translation dictionary, and an entry that does not exist. If the term is added as a new entry of this DB (100).

The terminology processor 240 separates the entry of the DB 100 and the terminology into single word entries and compound word entries, respectively. In addition, the terminology processor 240 records in the extended dictionary DB 900 for the single word entry where the band words are combined among the separated single word entries, and manually attaches the appropriate band word for the single word entry where the band words are not combined. Record in the extended dictionary DB (900). In addition, the terminology processor 240 records the separated compound word entry as it is in the extended dictionary DB 900.

For example, 1) a general translation dictionary DB 100

solution-> {solution, solution, description, solution},

fluid-> {fluid, liquid},

melting-> {melting, melting}, etc.,

2) In the existing terminology

Solution-> {solution},

Solution-> {solution, fluid},

Assuming that the solution is recorded as {solution, melting}, etc., the term comparison unit 210 may match the head language of the DB 100 and the band language of the terminology (eg, solution, fluid, melting). ) Compare / detect.

Then, since the terminology conversion unit 220 and the term removal unit 230 is an entry existing in the DB 100, the term translation unit 220 and the term removal unit 230 add a band word of the terminology to the corresponding headword of the DB 100. That is, solution becomes {solution, solution, explanation, solution, dissolution}, fluid becomes {fluid, liquid, solution}, and melting becomes {dissolution, melting} as before.

Since the terminology processor 240 is a single word entry with all the above-described solution, fluid, and melting, and the band word is attached, the terminology processing unit 240 is recorded in the extended dictionary DB 900 as follows.

solution-> {solution, solution, description, solution, dissolution},

fluid-> {fluid, liquid, solution},

melting-> {melting}

3 is a detailed block diagram illustrating the term processor of FIG. 1.

As shown in FIG. 3, the term processing unit 300 receives a large-capacity patent document composed of a starting language, and classifies it into an industrial field according to the IPC classification. A term extraction unit 330 for extracting unregistered terminology that is not listed in the translation dictionary DB 100, an unregistered term alignment unit 350 for sorting the extracted unregistered terminology in order of appearance, and an ordered unregistered term The terminology processor 240 separates a term into a single word entry and a compound word entry, and separately adds the term to the extended dictionary DB 900.

In addition, the term processor 300 may include a departure language input unit 700 for receiving a departure language patent document, a mapping table 320 for mapping between the IPC and the industrial classification for classification of the patent document, and a morpheme analyzer 340.

The term processing unit 300 configured as described above will be described in more detail.

The document classifier 310 receives a large-scale starting language patent document and classifies it into an industrial field according to the IPC classification with reference to the mapping table 320. Here, the industrial sectors according to the IPC classification are classified into 12 (ie, machinery, agriculture, forestry and fisheries, office supplies, textiles, beverage food, medical hygiene, sundries, electrical and electronics, mining metals, computers, civil engineering, and general chemical).

The term extracting unit 330 extracts the registered language of the patent field, which is not recorded in the DB 900 for the expansion dictionary, using the morpheme analyzer 340 of the patent documents classified as described above. Here, since the morpheme analyzer 340 is known to those skilled in the art, detailed description thereof will be omitted to clarify the present invention. In addition, the unregistered term alignment unit 350 sorts the extracted unregistered terminology in the order of high frequency.

Thereafter, the terminology processor 240 separates the terminology sorted in the order of high frequency for each field into a single word entry and a compound word entry. In addition, the terminology processor 240 records in the extended dictionary DB 900 for the single word entry where the band words are combined among the separated single word entries, and manually attaches the appropriate band word for the single word entry where the band words are not combined. Record in the extended dictionary DB (900). In addition, the terminology processor 240 records the separated compound word entry as it is in the extended dictionary DB 900.

For example, after extracting the unregistered terminology based on the starting language patent document described with reference to FIG. 3, an example of the extended dictionary DB 900 constructed by attaching a band word to an entry without a single word band word is shown in Table 1 below.

FIG. 4 is a detailed block diagram illustrating the bandword specialized unit of FIG. 1.

As shown in FIG. 4, the band word specialization unit 400 receives a large-capacity patent document composed of a target language and classifies it into an industrial field according to IPC classification, and a vocabulary on the classified patent document. A term analyzing unit 420 for classifying single words and compound words, a term sorting unit 440 for sorting the classified single words and compound words in frequency order according to patent fields, an unregistered term sorting unit 350 described above with reference to FIG. 3, The term selector 450 may include a term selector 450 that selects a band word specialized for a band word recorded in the DB 900 for the expansion dictionary based on the terminology list sorted by the term sorter 440 and the unregistered term sorter 350.

In addition, the band language specialization unit 400 may include a target language input unit 800 that receives a target language patent document, a mapping table 320 that maps between the IPC and the industrial classification for classification of the patent document, and a morpheme analyzer 340. The apparatus further includes a compound word automatic translation unit 460, an extension dictionary DB 900, and a patent translation dictionary DB 500 reflecting the bandword information to which the patent information is attached.

The bandword specializing unit 400 configured as described above will be described in more detail.

The document classifier 310 receives a large-capacity patent document composed of a target language and classifies it into an industrial field according to the IPC classification by using the mapping table 320. Here, the industrial sectors according to the IPC classification are classified into 12 (ie, machinery, agriculture, forestry and fisheries, office supplies, textiles, beverage food, medical hygiene, sundries, electrical and electronics, mining metals, computers, civil engineering, and general chemical).

The term analyzing unit 420 classifies the vocabulary on the classified patent document using a morpheme analyzer 340 as a single word and a compound word. The term alignment unit 440 sorts the single words and compound words classified as described above in high frequency order by patent field.

The compound word automatic translation unit 460 automatically translates the compound word without the target language band word from the extension dictionary DB 900 constructed in FIG. 3 and adds the compound word to the extension dictionary DB 900 described above. As a result of this, both the single word and the compound word recorded in the extended dictionary DB 900 have a target language band word. Here, the compound word automatic translation unit 460 may use a mechanical compound word translator, and in some cases, may be manually.

In addition, the term selector 450 is a list of target language terminology high frequency for each patent field sorted by the term sorter 440 and the starting language terminology high frequency order for each patent field sorted by the unregistered term sorter 350. Based on the list, the band word recorded for each patent field is selected for the band word recorded in the extended dictionary DB 900 (a detailed description of the band word selection will be described later based on FIG. 5). In this way, the patent translation dictionary DB 500 reflecting the information of the patent field can be constructed.

In order to help the above-described band word specializing unit 400, a DB 500 for patent translation dictionary is constructed by classifying band words for each patent field for entries having two or more band words existing in the extended dictionary DB 900. How to do this will be described with a specific example.

First, an example recorded in the extended dictionary DB 900 is shown as Table 2 described above. Among these, the headwords for entries with two or more bandwords are solution, fluid, and melting.

Subsequently, headings are sorted according to the high frequency order of the patent fields with respect to the target language sorted by the term alignment unit 440 via the document classification unit 310 and the term analysis unit 420. For example, in the case of solutions, in the general chemical field (e.g., "PAT-chemical general") and in the medical hygiene field (e.g., "PAT-medical hygiene"), {solution} is the default word and the default for all patents In the furnace, {solution, solution, explanation, solution, dissolution} is summarized in the band word. Because, in general chemical field and medical hygiene field, {solution} can be a band word in a specific field because the frequency of {solution} is used more frequently than {solution} which is the default of all patent fields.

An example of classifying band words by patent field is shown in Table 3 below.

entry Band word solution {PAT-Chemical Solution} {PAT-Hygiene Solution} {PAT-DEFAULT Solution, Solution, Description, Solution, Dissolution} fluid {PAT-DEFAULT Fluid, Liquid, Solution} melting {PAT-DEFAULT Molten, Melt} nitride_based {PAT-DEFAULT nitride_based} untrusted {PAT-DEFAULT unreliable} intermediate_transfer {PAT-DEFAULT intermediate_send} paintball {PAT-DEFAULT Paintball} in-cylinder {PAT-DEFAULT cylinder_in} pressurized_fluid {PAT-DEFAULT pressurized_fluid} crosslinked {PAT-DEFAULT Crosslink} alkoxylated {PAT-DEFAULT alkoxylation} condensable_hydrocarbon {PAT-DEFAULT Condensable Hydrocarbons}

On the other hand, in contrast to the above description, in the case of fluid, "PAT-DEFAULT" is assigned because there is no band word in a specific field which appears at a higher frequency than {solution}, which is the default in all patent fields.

In addition, in Table 2, a compound word without a band word is automatically translated by the compound word automatic translation unit 460, and a band word is attached to the headword.

FIG. 5 is a flowchart illustrating an operation of the term selector of FIG. 4, wherein the term selector 450 selects the terminology terminology based on the bandword recorded in the DB 900 for the extended dictionary by the bandword specialization unit 400. Illustrated.

First, when an entry recorded in the extended dictionary DB 900 is input, it is determined whether the current entry is the last (S501). As a result of the determination, if it is the last time, the entire operation is terminated.

Next, it is determined whether there is one band word of the headword for the entry (S503). As a result of the determination, if there is one, the band word for the corresponding headword is added / recorded in the patent translation dictionary DB 500 (S504), and step S501 is performed again. However, if there is more than one, step S505 is performed.

Then, since there are a plurality of band words for the current entry, one of them is set as a default band word in all patent fields (S505). That is, in the high frequency order list of target language jargon by patent field arranged by the term aligning unit 440, the band word used at the highest frequency throughout the patent field is determined as the default band word of the entire patent field.

Then, in the high-frequency order list of the starting language terminology for each patent field organized by the unregistered term sorting unit 350, the heading of the current entry has a specific cumulative frequency in the list (e.g., 70% of the cumulative frequency from the top of the total frequency). It is determined whether or not (S506).

As a result of the determination, the entry of the corresponding starting language headword is separated only (S507), and the default band word for each patent field is determined through the translator (S508). This decision is made manually in some cases.

If less than that, the band word of the specific field only if the default band word of the specific field is more frequent in the high frequency order list of the starting language terminology than the default band word of the entire patent field in the target language terminology high frequency order list. Is automatically set (S509). For example, in the case of the above-described solution, this case is the case where {solution} is used as a band word in the chemical general field and the medical hygiene field.

Subsequently, the band word determined or selected in steps S505 to S509 is recorded in the patent translation dictionary DB 500 (S510), and the next entry is repeatedly performed from step S501 to record in the extended dictionary DB 900. This operation is performed until the lost entry (S511).

While the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will recognize that various modifications or changes can be made without departing from the spirit and scope of the invention.

As described in detail above, according to the present invention, by using a conventional general translation dictionary, existing terminology, and linguistic resources readily available such as a large amount of patent documents, only experts in the relevant field For known patent document terminology, there is an effect of saving time and cost for constructing a large-capacity patent translation dictionary in which band words are divided by patent field.
