[0004]
In Japanese Patent Laid-Open No. 2001-249950 (hereinafter referred to as “conventional literature”), the similarity between the included information elements is calculated by comparing the community type with the personal information of the participant. By selecting the community that should provide information based on the statistical information, it is possible for the information provider to easily select the optimal community as the information providing destination, and to receive only the information preferred by the participants Proposal of information provision / collection device and method.
[0005]
In the technique of this prior art document, the type of community is determined by calculating the statistics of similarity for each community based on the personal information using gender, preference, age, region, etc. as personal information. Also, related terms may be extracted from keywords of personal information and based on them. For example, “UK” and “overseas travel” are extracted as related words from the keyword “London”.
[0006]
[Problems to be solved by the invention]
However, it is difficult to accurately create an item representing a community type, a keyword, and a related word for the keyword.
[0007]
If a similar relationship and related words are made narrow, it will not hit unless a part of the item is a keyword, and if a similar relationship and related words are made wide, it will hit a lot and it will not always be possible to select the community properly. .
[0008]
The present invention is intended to provide a community providing system and a community providing method that allow a user to appropriately select a desired community.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
(A) First embodiment
Hereinafter, a first embodiment of a community providing system and a community providing method according to the present invention will be described in detail with reference to the drawings.
[0012]
(A-1) Configuration of the first embodiment
FIG. 1 is a block diagram illustrating a configuration of a community providing system according to the first embodiment.
[0013]
In FIG. 1, the community providing system 1 is configured such that a server 3 on the Internet 2 can connect to a user terminal 4 via the Internet 2. Although not shown in FIG. 1, the server 3 can be connected to another server or the like via the Internet 2.
[0014]
The server 3 includes an HTTP daemon 10, a log analysis unit 11, an access log storage unit 12, a Web server 13, a community service unit 14, and various information databases 15. , H It has a TML parser 17 and an input / output device 18.
[0015]
Here, the Web server 13 functionally includes a communication tool 13a, a community service management unit 13b, a dictionary management unit 13c, a user registration / authentication unit 13d, and a community management unit 13e. The community service unit 14 includes a community information provision / collection unit 14a. Further, the various information databases 15 include a technical term dictionary information unit 15a, a user information unit 15b, a community classification information unit 15c, and a community information unit 15d.
[0016]
The user terminal 4 instructs the Internet 2 to search for a home page or a web page (hereinafter collectively referred to as a web page) 5. Here, the user who has concluded the community service provision contract with the operator of the server 3 can use the user terminal 4 to provide information about the desired community, and from the desired community. Information can be collected. For example, the user can input information provided on a Web page provided by the server 3 and can collect information in a Web page format.
[0017]
In the server 3, the HTTP daemon 10 transfers a Web page (HTML document) or the like according to a predetermined transfer protocol.
[0018]
The log analysis unit 11 obtains an access log from the web page to be searched from the user terminal 4 and communication information defining the user terminal 4 and stores the access log in the access log storage unit 12 and logs in the web server 13. Log out. When logging in, user authentication is required.
[0019]
The communication tool 13a in the Web server 13 bears a communication function with the user terminal 4, a communication function for searching a Web page, and the like.
[0020]
The community service management unit 13b communicates with the community service unit via the HTML parser 17 when providing information to a certain community by writing on the Web page, or when collecting information from the community by writing on the Web page. 14, a web page is given to execute an information providing process and an information collecting process related to the web page.
[0021]
Here, the HTML parser 17 extracts only the information provision part and the information collection request part from the input Web page (HTML document) based on the tag information and the like, and gives them to the community service unit 14. The tag information is returned to the information etc. and returned to the Web page (HTML document).
[0022]
In the community service unit 14, the information provision / collection processing unit 14a adds information to the community information unit 15d, which will be described later, modifies information in the community information unit 15d, Community information provided to the user from the unit 15d is collected.
[0023]
The technical term dictionary information section 15a in the dictionary database 15 stores various types of dictionary information. Each technical term dictionary (including the general term dictionary) in the technical term dictionary information unit 15a has a one-to-one correspondence with each community (community classification) described later. In other words, the technical term dictionary information unit 15a stores technical terms for each community.
[0024]
FIG. 2 shows an example of data in the technical term dictionary. One piece of data consists of a community name, headword, definition, comment, and author name. The community name is the name in the community classification, the headword is the technical term, the definition is the meaning and definition of the technical term, the comment is the free description column of the data, and the author name is the name of the user or system administrator who created it. In the comment, a comment by an arbitrary user such as when it was registered or “it is better to review the definition” is inserted.
[0025]
For example, in a community related to “dogs”, the name of the dog type is described in the headword so that each user can communicate smoothly, and the origin, appearance, and characteristics of the type of dog are described in the definition. The
[0026]
The user information section 15b of the dictionary database 15 stores information on a user who has concluded a contract using the server 3 with the operator of the server 3. The user information section 15b also stores information such as whether or not the registered user can receive community services.
[0027]
The community classification information section 15c of the dictionary database 15 stores information on the structure related to each community as shown in FIG.
[0028]
In FIG. 3, each community basically has a hierarchical structure of a tree structure. A general community is used as a root node, and a community when a specialized field or genre is roughly classified is provided in the next layer. The lower hierarchy is provided with a community when the higher-level specialized fields and genres are further classified, and the number of branches (hierarchy depth) reaching the terminal node need not be uniform.
[0029]
The community information section 15d of the dictionary database 15 stores information provided by the user (written by the user) for each community.
[0030]
The dictionary management unit 13c of the Web server 13 edits and manages the technical term dictionary information unit 15a.
[0031]
Whether the user registration / authentication unit 13d of the Web server 13 is a person who can register a user, authenticate whether a person who has accessed the server 3 is a legitimate user, or provide a service when a community service is required. It is to confirm.
[0032]
The community management unit 13e of the Web server 13 manages information in the community classification information unit 15c and the community information unit 15d. For example, when the user selects a desired community, a hierarchical structure of the community is provided, and when the desired community becomes clear, editing of the community information unit 15d is allowed.
[0033]
The input / output device 18 is used when the operator of the server 3 activates editing of a dictionary or edits a dictionary.
[0034]
Note that the system of the first embodiment can cope with simultaneous access from a plurality of users. For example, one set of community service unit 14 or HTML parser 17 may be used in a time-sharing manner to support a plurality of accesses, or a plurality of sets of community service unit 14 or HTML parser 17 may be prepared in advance. In addition, a plurality of accesses may be supported. In the latter case, each time access is requested, an original community service program or the like may be loaded into a plurality of prepared CPU main memories or the like so that a plurality of accesses can be handled simultaneously.
[0035]
FIG. 4 is a diagram in which the functional block is rearranged and rewritten from the relationship with the feature (community selection) of the first embodiment in the configuration shown in FIG.
[0036]
The community selection unit 20 performs processing so that a user can select a desired community. The community selection unit 20 corresponds to the log analysis unit 11, the communication tool 13a, the user registration / authentication unit 13d, the community management unit 13e, and the like in FIG.
[0037]
(A-2) Operation of the first embodiment
Next, characteristic operations of the community providing system according to the first embodiment will be described with reference to the drawings.
[0038]
(A-2-1) Technical term user registration operation
Next, an operation when a user registers a technical term in the technical term dictionary information unit 15a will be described with reference to a flowchart of FIG.
[0039]
For example, in this processing, information exchanged between the user terminal 4 and the server 3 is information in the format of an HTML document. Moreover, although registration of technical terms may be performed after entering a community desired by the user, FIG. 5 shows a case where technical terms are registered without entering the community.
[0040]
For example, the user uses the user terminal 4 to display a predetermined Web page provided by the server 3 and to instruct a technical term registration mode.
[0041]
At this time, first, the server 3 (user registration / authentication unit 13d) determines whether or not the user can register technical terms, and the user is not a person who can register technical words. Then, the server 3 replies to that effect, ends the registration process, and enters the process shown in FIG. 5 if the user is a person who can register a specialized word.
[0042]
The server 3 (dictionary management unit 13c) transmits a technical term registration input screen to the user terminal 4 and takes in registered technical term information from the user terminal 4 (step 101). In addition, the user sends a plurality of registered technical term information together. Ru You can do it. Hereinafter, for simplification of explanation, it is assumed that one piece of registered technical term information is transmitted.
[0043]
When the registered technical term information is given, the server 3 (dictionary management unit 13c) searches the technical term dictionary information unit 15a with the headwords included therein (step 102), and the technical term data having the headwords is obtained. It is determined whether or not a search has been performed (step 103).
[0044]
If the technical term data including such a headword does not exist in the technical term dictionary information unit 15a, the given technical term data is registered in the technical term dictionary information unit 15a (step 104), and this is indicated to the user terminal 4 To end the series of processing.
[0045]
On the other hand, when the technical term data including the headword of the technical term data to be registered by the user already exists in the technical term dictionary information unit 15a, the community name in the existing technical term data and Send definition to user terminal 4 and register technical term data requested for registration The The user confirms whether or not to perform a new operation (steps 105 and 106).
[0046]
When the user confirms the intention to newly register, the server 3 (dictionary management unit 13c) registers the given technical term data in the technical term dictionary information unit 15a (step 104), and informs the user of that fact. It returns to the terminal 4 and a series of processes are complete | finished.
[0047]
On the other hand, when an intention confirmation that new registration is unnecessary is obtained from the user, the user is prompted to confirm whether or not to correct and register (step 107).
[0048]
When the user's intention confirmation that the corrected registration is unnecessary is obtained, the series of processes is terminated. When the user's intention confirmation that the corrected registration is required is obtained, the one used for the correction is selected from all the technical term data including the corresponding headword obtained from the search of the technical term dictionary information section 15a. (Step 108), the selected terminology data is corrected to be additionally registered or re-registered (step 109), and the series of processes is terminated.
[0049]
If it is not preferable for each user to freely register or add to the technical term dictionary information unit 15a, only the community operator may register, add, or delete. .
[0050]
(A-2-2) Community selection operation
Next, an operation when the user selects a community to join will be described with reference to the flowchart of FIG.
[0051]
For example, the user uses the user terminal 4 to display a predetermined Web page provided by the server 3 and instruct a community participation mode.
[0052]
At this time, first, the server 3 (user registration / authentication unit 13d) determines whether or not the user is a person who can participate in the community. If the user is able to participate in the community, the process shown in FIG. 6 is entered.
[0053]
The server 3 (community service management unit 13b) obtains a hierarchical structure of community classification from the community classification information unit 15c, can specify a participating community specifically from the hierarchical structure, and searches and selects a participating community from input of technical terms A selection input screen indicating that it can be transmitted is transmitted to the user terminal 4, and the content of the reply is determined (steps 200 and 201).
[0054]
When the community to participate in is specifically designated, the server 3 ends the series of processes. At this time, the process shifts to specific community service processing.
[0055]
When a technical term (headword) is input to the selection input screen of the participating community, the server 3 sends technical term data including such technical term (headword) from the technical term dictionary information unit 15a. A search is performed (step 202), and it is determined whether or not the corresponding technical term data exists (step 203).
[0056]
If the corresponding technical term data does not exist, the server 3 returns to step 200 and causes the user terminal 4 to transmit the selection input screen of the participating community. At this time, a message indicating that there is no corresponding community in the input technical term (headword) is also displayed.
[0057]
On the other hand, if there is at least one technical term data including technical terms (headwords) input by the user in the technical term dictionary information unit 15a, the server 3 will search for all technical term data obtained by the search. The community name and definition are transmitted to the user terminal 4 (step 204), and the community designated by the user is captured (step 205). Also at this time, if the community to participate in is specifically designated, the server 3 ends the series of processes. Then, the process shifts to specific community service processing.
[0058]
In addition to sending the community name and definition in the terminology data obtained from the search, if the community specified by the community name is in a lower hierarchy, the community name of the higher community is also clarified and sent, You may make it permit designation | designated of a high-order community.
[0059]
For example, if the user wants to find a community related to the computer address and has searched for the community “computer” from the display of the hierarchical structure of the community but cannot find it (see FIG. 3), enter the technical term “address”. Then, the community names “computer” and “golf” are returned (see FIG. 2). Here, as shown in FIG. 2, even if there are two communities that use “address” as a technical term, the definition etc. is transmitted as judgment material, so it is called “computer” in line with the user's intention. You can find a community.
[0060]
(A-3) Effects of the first embodiment
According to the first embodiment, when the community to be joined cannot be determined from the community name or the like, the community system side to be joined is prepared by inputting the technical terms of the community to be joined. You can get the community name you have and join the desired community.
[0061]
Here, technical terms unique to the community are registered in the technical term dictionary information unit 15a and correspond to the specialized technical terms for each community, so that the desired community can be found accurately.
[0062]
As a result, a keyword database used only for community selection can be eliminated.
[0063]
(B) Second embodiment
Next, a second embodiment of the community providing system and the community providing method according to the present invention will be described in detail with reference to the drawings.
[0064]
(B-1) Configuration of the second embodiment
FIG. 7 is a block diagram illustrating the configuration of the community providing system according to the second embodiment, and the same and corresponding parts as those in FIG. 1 according to the first embodiment are denoted by the same corresponding reference numerals.
[0065]
The community providing system of the second embodiment has a configuration related to machine translation in addition to the configuration of the first embodiment. That is, it includes a web translation processing unit 13f, a machine translation system 25, a dictionary converter 26, and a translation result information unit 15e.
[0066]
When the web page or the like needs to be translated, the web translation processing unit 13f gives the machine translation system 25 a web page via the HTML parser 17 and executes the translation of the web page.
[0067]
In the machine translation system 25, the translation engine 25a is a part that executes machine translation, and the dictionary unit 25b stores dictionary information used when the translation engine 25a performs machine translation. Note that dictionary information (technical term data) stored in a technical term dictionary information unit 15a described later is converted for the translation engine 25a by the dictionary converter 26 and stored in the dictionary unit 25b.
[0068]
The translation result information unit 15e stores translation results for other community participants in response to a request from a user who has requested machine translation.
[0069]
In the case of the second embodiment, the configuration of technical term data in the technical term dictionary information unit 15a is slightly different from that of the first embodiment as shown in FIG. That is, the technical term data is different in that it includes a community name, a headword, a translation, a definition (which can be omitted), a comment, and an author name, and a translation of the headword is added. Depending on the type of translation engine 25a, information such as part-of-speech information may be included.
[0070]
FIG. 9 is a diagram in which the functional block is rearranged and rewritten from the relationship with the feature (community selection) of the second embodiment in the configuration shown in FIG.
[0071]
(B-2) Operation of the second embodiment
Also in the second embodiment, the operation of registering the technical term data (opposite data) in the technical term dictionary information unit 15a is the same as that of the first embodiment, and the description of the operation is omitted. However, the technical term data to be registered has items shown in FIG.
[0072]
Next, an operation for selecting a community to be joined by the user and an operation for allowing the user to select a community of a target document for machine translation will be described with reference to the flowchart of FIG.
[0073]
For example, the user uses the user terminal 4 to display a predetermined Web page provided by the server 3 and instructs a community participation mode or a machine translation mode.
[0074]
At this time, first, the server 3 (user registration / authentication unit 13d) determines whether or not the user can participate in the community and whether or not the user can receive the machine translation service. If a negative result is obtained, the server 3 returns that fact and ends the process. If a positive result is obtained, the server 3 enters the process shown in FIG.
[0075]
The server 3 (community service management unit 13b) can obtain a hierarchical structure of community classification from the community classification information unit 15c, can specifically specify a community from the hierarchical structure, and can search and select a desired community from input of technical terms. Is sent to the user terminal 4 to determine the reply content (steps 300 and 301). The terminology input here may be either a headword language or a bilingual language, and may be both languages.
[0076]
When the desired community is specifically designated, the server 3 ends the series of processes. At this time, the process shifts to a specific community service process or a specific machine translation process.
[0077]
When technical terms (entry words and / or translations) have been input on the selection input screen of the community, the server 3 uses technical terminology data including such technical terms (entry words and / or translations) as technical terms. A search is performed from the dictionary information section 15a (step 302), and it is determined whether or not the corresponding technical term data exists (step 303).
[0078]
If the corresponding technical term data does not exist, the server 3 returns to step 300 and causes the user terminal 4 to transmit a selection input screen of a desired community. At this time, a message indicating that there is no community corresponding to the input technical term (entry word and / or translation) is also displayed.
[0079]
On the other hand, if at least one terminology data including the terminology (entry word and / or translation) input by the user exists in the terminology dictionary information unit 15a, the server 3 can search for all the terminology obtained by the search. The community name and translation in the term data are transmitted to the user terminal 4 (step 304), and the community designated by the user is captured (step 305). Also at this time, the process proceeds to a specific community service process or a specific machine translation process, and the series of processes ends. Then, the process shifts to specific community service processing.
[0080]
Also in the second embodiment, in addition to the transmission of the community name and the translation in the technical term data obtained by the search, if the community specified by the community name is a lower hierarchy, the community name of the upper community is also the same May be transmitted to allow designation of a higher-level community.
[0081]
For example, even if it is not a technical term describing a definition, such as the title of a movie or a theater, if it is a technical term describing a translated word, the user can search for a desired community through a search of the technical term dictionary information unit 15a. Can be found. Also, for example, if you want to find a community to find out about a molecule, but you do n’t know the name of the community, enter the word “numerator” and the “math” community is “numerator” and the “physics” community Since it is understood that it is “molecule” (see FIG. 8), it can be clearly distinguished by the English translation, and the user who is better at English can select the intended community.
[0082]
In machine translation processing, by specifying a community as described above, technical terms related to that community ( Top Information (including community technical terms) is extracted from the technical term dictionary information unit 15a and unnecessary item information is removed via the dictionary converter 26, and then set in the dictionary unit 25b of the machine translation system 25. After that, the designated document is machine-translated.
[0083]
For example, when a document is translated in the “general” community, “tee” is translated as “tea”, and when a document is translated in the “golf” community, “tee” is translated as “tee”.
[0084]
(B-3) Effects of the second embodiment
By searching from the bilingual dictionary of the community, words with translations unique to the community are registered, so it is possible to deal with unique expressions for each community, and when there are multiple data with the same headword, it differs depending on the translation Is clear, so that there is an effect that a desired community can be accurately found. Moreover, when translating, there is an effect that it is possible to translate with an accurate translation for each community.
[0085]
Also in the second embodiment, when the community to be joined cannot be determined from the community name or the like, the system side of the community to join by preparing the entry and / or translation of the community to join is prepared. You can get the name of the community you are doing and join the desired community.
[0086]
Here, headwords and / or translation words unique to the community are registered in the technical term dictionary information section 15a, which corresponds to technical terms unique to each community, and search based only on headwords In addition, since a search based only on a translation word and a search based on both a headword and a translation word are possible, a desired community can be accurately found.
[0087]
As a result, a keyword database used only for community selection can be eliminated.
[0088]
(C) Other embodiments
In the second embodiment, the system capable of supporting both the information providing and collecting community service and the machine translation service has been described. However, a system corresponding only to the machine translation service may be used. Even in this case, the machine translation service is a community service in which a plurality of users can share and use technical terms and can also perform registration and the like. The term “community” in the claims also applies to a system that performs only such a machine translation service.
[0089]
In each of the above embodiments, when searching for technical terms, in addition to the community name, Definition Other information such as translation and other information is also shown to be transmitted to the user terminal to select the community, but only the community name may be transmitted to the user terminal to select the community.
[0090]
Further, in each of the above-described embodiments, the number of technical terms input to obtain a community name is one, but a plurality of technical terms may be used. In such a plurality of cases, a search condition may be specified by a search expression for a plurality of technical terms. For example, in the case of two technical terms, the server 3 may be made to search for a community name that includes both of the two technical terms, and the server 3 may be made to search for a community name that includes even one of them. Alternatively, the server 3 may be made to search for a community name that includes one technical term and does not include one technical term.
[0091]
【The invention's effect】
As described above, according to the community providing system and the community providing method of the present invention, the user can accurately select a desired community.
