Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a language processing system, and more particularly to a language processing system for performing language processing by a client / server system.

[0002]

2. Description of the Related Art Recently, various systems for performing various language processing such as document retrieval and translation on a computer interconnected via a network have been proposed. Such a method has been proposed.

As a first method, a system has been proposed in which a document to be subjected to language processing is input to the client side and language processing is executed on the input document on the server side. Specifically, in such a system, a program and a dictionary for executing language processing are stored in the server, and the client sends an input document for language processing to the server via the communication line. Then, the server performs language processing such as translation on the received document, and returns the obtained processing result to the client.

As a second method, there is proposed a system in which a server loads a program or dictionary required for language processing into a client and the client performs language processing of an input document according to the loaded program or dictionary. ing. Specifically, in such a system, a program or a dictionary for executing language processing is stored in the server, and when the server makes a language processing request, the server performs language processing via the communication line to the client. Load the required programs and dictionaries. Then, the client changes the input document for language processing to
Perform language processing according to the loaded programs and dictionaries.

[0005]

However, in the above-mentioned first method, since the dictionary used for language processing is shared by the clients, there is an advantage that the dictionary is collectively managed and the storage capacity of the dictionary is saved. However, when a plurality of clients make processing requests to the server at the same time, the load is concentrated on the server, which requires a large amount of processing time.

On the other hand, in the second method, although the language processing is performed on the client side, the load is distributed, but when a large-scale program or dictionary is used, a large amount is required to load the program or dictionary from the server to the client. There is a problem that it takes a long time.

The present invention has been made in view of the above problems, and an object thereof is to provide a language processing system in which the processing time required for language processing is reduced.

[0008]

The invention according to claim 1 is
In order to solve the above problem, a client that issues a language processing request is connected to the client via a communication line, and the processing result obtained by executing the language processing according to the language processing request issued from the client is given to the client. In the language processing system including a server for transferring, the client analyzes the character string input from the input means for inputting the character string to be subjected to the language processing and the character string input from the input means, and For words that have different notations ,
Only a different word to create a different word list including the different word, and the language processing request, and information corresponding to the different word list created by the word extracting means to the server. A first communication means for transmitting, the server, using the word as a search key, a dictionary storing word information corresponding to the word, and word information corresponding to the different word in the different word list,
It is configured to include a dictionary search unit that refers to the dictionary to obtain a search result, and a second communication unit that transmits the search result obtained by the dictionary search unit to the client.

That is, according to the above-mentioned configuration, the client can input the character string to be subjected to the language processing,
The words having different notations, that is, different words are extracted, a different word list including the different words is created, and information corresponding to the different word list is transmitted to the server, while the server is the words corresponding to the different words. Since the information is searched by referring to the dictionary and the search result is transferred to the client, duplicate words in the input character string are not duplicately sent from the client to the server, and as a result, the server does not. , Such duplicate words are not duplicately searched in the dictionary. Therefore, the amount of data transmitted during the dictionary search between the client and the server can be reduced, and the dictionary search time at the server can be reduced, so that the processing time required for the language processing of the entire language processing system can be significantly reduced. Is possible.

In order to solve the above problems, a second aspect of the present invention is to connect a client that issues a language processing request to the client through a communication line, and perform language processing in accordance with the language processing request issued from the client. A language processing system comprising a server for transferring a processing result obtained by execution to the client, wherein the client is an input means for inputting a character string to be subjected to the language processing, and a first type word. As the search key
A first dictionary that stores word information corresponding to different words and a character string that is input from the input unit are analyzed to identify words that are different from each other in the character string and that are duplicate words.
As a result, a word extracting unit that extracts only one word as a different word and creates a different word list including the different word,
A first search is performed for word information corresponding to a different word in the different word list with reference to the first dictionary to obtain a search result.
Dictionary search means, and first communication means for transmitting to the server information corresponding to an unsearched different word not searched by the first dictionary search means, together with the language processing request,
Wherein the server uses a second type word as a search key, stores a second dictionary that stores word information corresponding to the second type word, and word information corresponding to the unsearched different word, Second dictionary searching means for referring to the second dictionary to obtain a search result, and second communication means for transmitting the search result obtained by the second dictionary searching means to the client,
It is configured to include.

That is, according to the above configuration, the client and the server are provided with the first and second dictionaries, respectively, and the client is a character string to be subjected to the language processing, in which words different in notation, that is, , Extracting a different word, creating a different word list including the different word, searching the word information corresponding to the different word in the different word list with reference to the first dictionary, and no search result is obtained. While transmitting the unsearched different word to the server, the server refers to the second dictionary for the word information corresponding to the unsearched different word and transfers the obtained search result to the client. Therefore, from the client, only the words that do not overlap each other in the input character string and whose word information is not searched in the first dictionary are transmitted to the server, and the server relates to such unsearched words. Only word information is searched in the dictionary. Therefore, the data transmission amount at the time of the dictionary search between the client and the server can be reduced, and
The dictionary search time in the server can be reduced, and the processing time required for the language processing of the entire language processing system can be significantly reduced.

Further, like the invention according to claim 3, in the invention according to claim 2, the word of the first type is replaced with the word of the second type.
It may be a word that appears more frequently in the character string than the seed word. In this case, since the word information about the frequently appearing words is stored in the client and the word information about the less frequently appearing words is stored in the server, it is possible to transfer the less frequently appearing words from the client to the server. Therefore, it becomes possible to further reduce the amount of data transmission at the time of the dictionary search between the client and the server.

Further, as in the invention described in claim 4, in the invention described in claim 1 or 2, the different word list is
The different word may be configured to be associated with position information indicating the position of the different word in the character string. Therefore, since the different word list is configured by associating the different words with the position information indicating the position of the different words in the character string, it is easy to associate the result of the dictionary search with the original character string. Becomes This is especially useful when translating a character string.

Further, as in the invention described in claim 5, in the invention described in any one of claims 1 to 4, the word information may be part-of-speech information indicating a part of speech of the word. Therefore,
It is possible to retrieve the part-of-speech information of the word in the character.

FIG. 15 shows a second example created by the process on the server 3 side in the dictionary search process.
It is a figure which shows the different word list with a search result of.

The dictionary search process executed by the language processing system 1 will be described below with reference to FIG. 12
Before executing the dictionary search process shown in
Also, it is assumed that the server 3 has already been turned on and the initial settings have been completed.

First, from the input unit 21 of the client 2,
For example, The contact glass is the surface on which a
docment is placed for scanning. "(step S20), the CPU of the client 2
27 analyzes the appearance position (appearance order) of each word in the input character string (step S21), further extracts a different word in the character string (step S22), and extracts the extracted "different word". , Create a different word list as shown in FIG. 4 in which the appearance positions in the character string of the "different word" are associated,
Store in the different word list storage unit 23 (step S2
3).

Next, the CPU 27 searches the word information corresponding to each different word in the created different word list shown in FIG. 4 by referring to the local dictionary 26 shown in FIG. 10 (step S24), and performs the search. The word information is added to the different word list shown in FIG. 4 to create a different word list with the first search result as shown in FIG. 13 (step S
25). The first different word list with search results shown in FIG. 13 indicates that the word information of “contact”, “glass”, and “surface” of the “different word” has not been searched.

Then, the CPU 27 executes the first operation shown in FIG.
The unsearched “different word” and the corresponding ““ appearance position ”are extracted from the different word list with search result of (1) to create an unsearched list as shown in FIG. 14 (step S26). Subsequently, the communication unit 24 of the client 2 transmits a search request signal together with the unsearched list shown in FIG. 14 to the server 3 (step S27).

On the other hand, when the communication unit 31 of the server 3 receives the search request signal and the unsearched list transmitted from the client 2 (step S30), the CPU 35 causes the word information corresponding to each different word in the unsearched list. Is searched with reference to the remote dictionary 38 (step S31), the searched word information is added to the different word list shown in FIG. 14, and the different word list with the second search result as shown in FIG. 15 is added. Is created (step S32). Next, the communication unit 31 of the server 3 transmits the different word list with the second search result shown in FIG. 15 to the client 2 (step S
33), the dictionary search process on the server 3 side ends.

On the other hand, when the communication unit 24 of the client 2 receives the second different word list with search result shown in FIG. 15 transmitted from the server 3 (step S28), the CPU 27 of the client 2 shows in FIG. 15 is added to the first different word list with search result and the word information of the second different word list with search result shown in FIG.
A different word list with a search result is created (step S29), and the dictionary search process on the client 2 side is terminated.

As described above, in the second embodiment, the client 2 and the server 3 are provided with the local dictionary 26 and the remote dictionary 38, respectively. Then, the client 2 extracts words having different notations, that is, different words from the input character string to be subjected to the language processing, creates a different word list including the different words, and creates the different word list. This is a configuration in which word information corresponding to a different word therein is searched with reference to the local dictionary 26, and an unsearched different word for which no search result has been obtained is transmitted to the server 3. On the other hand, the server 3 is configured to search the word information corresponding to the unsearched different word by referring to the remote dictionary 38, and transfer the obtained search result to the client 2.

Therefore, from the client 2, only the words which do not overlap each other in the inputted character string and whose word information is not searched in the local dictionary 26 are transmitted to the server 3, and the server 3 takes such a word. Only the word information related to the word not searched is searched in the dictionary. Therefore, it is possible to reduce the amount of data transmission at the time of the dictionary search between the client 2 and the server 3, and it is possible to reduce the dictionary search time at the server 3, which significantly reduces the processing time required for the language processing of the entire language processing system. Can be reduced to.

Further, in the above-described second embodiment, the local dictionary 26 of the client 2 stores the word information about the frequently appearing words, and the remote dictionary 38 of the server 3 stores the word information about the less frequently appearing words. Because of the configuration, words that occur less frequently are transferred from the client 2 to the server 3, and it is possible to further reduce the amount of data transmission at the time of dictionary search between the client 2 and the server 3.

In the first and second embodiments described above,
Dictionaries (Dictionary 33, Local dictionary 26, Remote dictionary 3
Although the part-of-speech information is stored as the word information in 8) and the part-of-speech information is searched, the word information stored in the dictionary is not limited to the part-of-speech information, and for example, the corresponding Japanese notation is stored. Is also good. Further, the word information is not limited to one type of information, and a plurality of types of information may be stored, and for example, two types of the above-mentioned part-of-speech information and Japanese notation may be used.

Further, in the above-mentioned first and second embodiments, an example of retrieving the part-of-speech information of a word in an English text is shown. The present invention is applicable to Japanese as well, because there are a plurality of overlapping words.

[0074]

As described above, according to the invention of claim 1, the duplicated words in the input character string are
Duplicates are not sent from the client to the server, so that the server does not duplicate search such duplicate words in the dictionary. Therefore, the data transmission amount at the time of the dictionary search between the client and the server can be reduced, and
Since the dictionary search time in the server can be reduced, the processing time required for language processing of the entire language processing system can be significantly reduced.

According to the second aspect of the present invention, the client transmits only the words that do not overlap each other in the input character string and whose word information is not searched in the first dictionary to the server. At the server, only the word information regarding the unsearched word is searched in the dictionary.
Therefore, it is possible to reduce the amount of data transmission at the time of the dictionary search between the client and the server, and it is possible to reduce the dictionary search time at the server, which significantly reduces the processing time required for the language processing of the entire language processing system. It becomes possible.

According to the invention described in claim 3, in addition to the effect of the invention described in claim 2, word information regarding a word with high appearance frequency is stored in the client, and word information regarding a word with low appearance frequency is stored in the server. Since the word is stored with a low frequency, the words that appear less frequently are transferred from the client to the server, and the amount of data transmission when searching the dictionary between the client and the server can be further reduced.

According to the invention described in claim 4, in addition to the effect of the invention described in claim 1 or 2, the different word list includes the different words and the position information indicating the position of the different words in the character string. Since and are associated with each other, the process of associating the result of the dictionary search with the original character string becomes easy. This is especially useful when translating a character string.

According to the invention described in claim 5, in addition to the effect of the invention described in any one of claims 1 to 4, it is possible to retrieve the part of speech information of the word in the character.
