Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a browsing client server system in which a client browses a content file composed of a large number of pages stored in a server, and in particular, designates and browses only a predetermined page of a content file in a server at the client, or It is related with the browsing client server system which can attach only the keyword and mark of this, or can browse only the page which attached the keyword.
[0002]
[Prior art]
Nowadays, with the development of computers and data communication technologies, it is widely performed that a lot of information related to a predetermined matter is collected in a storage device of a computer and used by referring to necessary information when necessary. Examples of such a set of information include a dictionary file that collects interpretations of words, an information file that collects business information such as business reports, an information file that collects management information such as personnel information, and a photo book. As mentioned.
[0003]
Particularly recently, with the development of computer communication networks such as the Internet and LAN, it has been widely performed that a large number of image information such as photographs is stored in a predetermined server and image data is distributed at the request of a client.
[0004]
The present invention relates to search, distribution, and use of such information, but in order to clarify the invention, some terms used in this specification are defined here.
[0005]
The “server” and “client” are a plurality of computers that constitute a system (client server system) via communication means and perform predetermined information processing in cooperation with each other. The server is a computer that performs predetermined processing and output in response to a client request. A client is a computer that requests processing or output from a server. Servers and clients are logical entities, and there is no limit to the physical number, and there is no limit to the spatial distance. That is, there are cases where two adjacent computers construct a client-server system, a system in which a large number of terminals are connected as clients to one server having a large processing capacity, or a computer system connected by a communication network. A client-server system can be constructed.
[0006]
The “communication means” for connecting the server and the client may be any means for exchanging data and commands so that the server and the client can perform cooperative processing, and may be any of a single communication line, a communication network, a LAN, and the Internet. .
[0007]
The information stored in the server includes image data such as photographs and document data such as documents, which are collectively referred to as “content”.
[0008]
Further, the term “browsing” included in the name of the present invention refers to browsing the contents of the contents of the server.
[0009]
Now, a conventional technique for browsing the contents of the server will be described using a case where the server is on the Internet.
[0010]
Conventionally, when browsing the contents of a server on the Internet, the client starts up browsing software called a browser, accesses (connects) to the server, accesses a predetermined content file on the server, downloads, that is, the client from the server Enable transfer to. Here, in order for the user to proceed and browse the contents of the content file, the content file is once downloaded to the client, and then the content is viewed by the browser function on the client side.
[0011]
[Problems to be solved by the invention]
However, the conventional browsing technology described above has low information use efficiency and communication efficiency, and the hardware and the network on the client side are heavily loaded.
[0012]
As described above, conventionally, in order to view the content stored in a server on the Internet, the entire content must first be downloaded to the client side.
[0013]
However, when the content includes a lot of image data, it takes a long time to transfer. This is because image data generally has a large amount of data, and thus it is necessary to take time for the current communication means.
[0014]
Until the entire content has been transferred, the client cannot see the content, so the user has to wait for the transfer to finish, and in spite of having to wait for such a long time. Often, the content of the content actually viewed is only a small part of the content.
[0015]
In this case, the time for referring to the information is extremely short compared with the time for acquiring the information, and the efficiency is very low in terms of information use. In addition, hardware resources such as a computer and a communication network are used to transfer data that is not actually referred to.
[0016]
Conventionally, since the entire content is first transferred to the client, a large amount of data must be stored in the client storage device, and the client is inevitably required to have a large storage capacity. In addition, since a large amount of data is processed, it may be a burden on the information processing of the client.
[0017]
In view of the above-mentioned problems of the prior art, the problem to be solved by the present invention is that it is possible to quickly acquire only the information required by the user among the contents of the server, and to the hardware of both the server and the client The object is to provide a browsing client server system with a low load.
[0018]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings attached to the application.
[0032]
FIG. 1 shows the configuration of a browsing client server system according to an embodiment of the present invention.
[0033]
As shown in FIG. 1, the browsing client server system 1 according to the present embodiment includes a server 2, a client 3, and communication means 4.
[0034]
As described above, the server 2 is a computer that performs predetermined processing and output in response to a request from the client 3. The client 3 is a computer that requests the server 2 for processing and output. The server 2 and the client 3 are logical entities and are not limited to physical configurations. In other words, as long as it is a computer that has a relationship of performing processing, output, and cooperation processing according to a request as described above, it is not related to their physical arrangement, configuration, or number. In terms of time, the server 2 and the client 3 are not fixed. For example, there may be a plurality of computer systems connected by a communication network, where the computers request each other for processing and are in a requested relationship. In this case, when one computer functions as a server, Sometimes when acting as a client. FIG. 1 shows a case where a pair of computers functions as a server and a client in a fixed manner for easy understanding. However, as described above, the present invention is not limited to the configuration shown in FIG.
[0035]
The server 2 and the client 3 are connected by communication means 4. The communication means 4 includes a communication line, a communication device such as a modem, and software for controlling communication. The communication means 4 can be any communication network including a single communication line connecting a pair of computers, a LAN, the Internet, and the like.
[0036]
The server 2 has at least one content file 5a, 5b, 5c,... The content management means 6 functions as an interface with the client 3 and manages the content file 5 (5a, 5b, 5c,...).
[0037]
The content file 5 is a file that collects information based on documents, images, sounds, and the like. Content refers to the information content. The same type of information is gathered in one content file 5, and usually consists of a number of pages due to the browser function.
[0038]
According to the file structure of the present invention, the content file 5 includes a number of page files 7i (i = 1,..., N) corresponding to the apparent pages of the content, and each page file 7i (i = 1,. , N) has an index file 8 in which page numbers and addresses are entered.
[0039]
In FIG. 1, 00001.tif, 00002.tif,..., 0000n.tif are given as file names of the page file 7i (i = 1,..., N). Yes, the numbers such as 00001, 00002,..., 0000n of the file names do not correspond to the apparent page numbers of the content file 5. This will be described later with a specific example.
[0040]
The index file 8 has a certain rule that the file name of each page file 7i (i = 1,..., N), the apparent page number on the content file, and the address of the stored location can correspond to each other. Filled in by
[0041]
The content management means 6 is a means for receiving a content browsing request from the client 3 and searching for and outputting a designated content file 5 or page file 7i (i = 1,..., N). The content management means 6 also performs content management such as addition, change, and deletion of the content file 5, page file 7i (i = 1,..., N) and index file 8.
[0042]
For the server 2, the client 3 includes request means 9, content operation means 10, and display means 11.
[0043]
The requesting unit 9 is a unit that requests the server 2 to output data or files in the content, or to add or update a predetermined file as will be described later.
[0044]
As will be described later, the content operation means 10 uses the index file 8 of a predetermined content file to search for content (page file) that the user desires to browse or to select content (page file) designated by the user. It is means for receiving from the server 2 and displaying it on the display means 11. In other words, the content operating means 10 can be said to be a means for performing various operations (searching and displaying) for browsing the content on the server 2 as if it were actually on the client 3. Note that the content operation means 10 includes known input means for a user to input a command or to search and specify a predetermined page. This input means may be the same as the input means of the client 3.
[0045]
In order to perform various operations for browsing, the content operation means 10 first inputs an index file 8 of a predetermined content file 5, extracts data (index data) in the index file 8, and stores them in a table. Alternatively, a database is formed, and a predetermined page file 7i (i = 1,..., N) is searched using the index data table or database. Note that a method of searching for a predetermined page file 7i (i = 1,..., N) will be further described later.
[0046]
The display means 11 is means for displaying a predetermined page file 7i sent from the server 2 to the client 3 in a predetermined format by the action of the requesting means 9 and the content operation means 10. The predetermined format refers to a display format in which, for example, each page file 7i of content is displayed as if it is a book page. The format may be arbitrary as long as the contents of the page file 7i can be browsed.
[0047]
The above is the description of the configuration of the browsing client server system 1. Next, the flow of processing for browsing content in the browsing client server system 1 will be described with reference to FIG.
[0048]
As shown in FIG. 2, browsing of predetermined content by the browsing client server system 1 designates a predetermined content file 5 (5a, 5b,...) From the client 3 to the server 2 and transmits a request to view it. (Step S100).
[0049]
The content management means 6 of the server 2 that has received the request transmits only the index file 8 of the designated content file 5 (5a, 5b,...) To the request means 9 of the client 3 (step S110).
[0050]
The index file 8 is sent to the content operation means 10 via the request means 9. The content operation means 10 extracts the index data in the index file 8 and creates a table or database (step S120).
[0051]
The user designates a page desired to be browsed by the content operating means 10 using the index data table or database (step S130). This specific page designation method will be described later.
[0052]
After the predetermined page file is designated by the user, the file name of the page file designated by the user and the address where the page file is stored are sent from the request unit 9 of the client 3 to the content management unit 6 of the server 2. It is transmitted (step S140).
[0053]
The content management unit 6 of the server 2 that has received the user-specified file name and address acquires the corresponding page file by the file name and address, and transmits it to the request unit 9 of the client 3 (step S150).
The page file is sent from the request unit 9 of the client 3 to the display unit 11 and displayed by the display unit 11 in a predetermined format (step S160).
[0054]
Through the processes in steps S100 to S160, the user designates a predetermined page in the content file, and only necessary pages are sent from the server 2 to the client 3 and displayed.
[0055]
Here, a method for searching and specifying a page file that the user desires to browse will be described. FIG. 3 illustrates the necessary page file search and designation method in steps S120 and S130 in the series of processes described above.
[0056]
The upper part of FIG. 3 shows an index file 8 and the lower part shows a table / database of index data.
[0057]
The index file 8 is described based on a certain rule so that the file name, page number, and address of the page file 7i (i = 1,..., N) can be handled. “Fixed rules” means, for example, the order of index data, such as the page number next to the file name, the address next to the page number, the file name, the page number, the number of digits in the address, numeric data, and character data This is an agreement regarding the format of the data type.
[0058]
The content operation means 10 extracts index data such as a file name, a page number, and an address based on the description rule of the index file 8, and configures a table or database as shown in FIG.
[0059]
In this index data table or database, each page file 7i included in the content file 5 constitutes one record. In the record of each page file 7i, the address (for example, http://www.xxx/.../00001) where the page file 7i is stored is always described. As shown in FIG. 3, the order of the file names does not always match the apparent page number of the content. For example, file 00002tif is apparently located on the fifth page of the content. This is because the page file input order and the apparent page position of the content do not always match.
[0060]
The file name, page number, and address are fields (data items) of the table or database. The index data table or database is preferably provided with a mark column indicating the presence / absence of designation, a pointer column indicating the position of the pointer, and the like.
[0061]
According to the index data table or database configured as described above, it is possible to sort (rearrange in a certain order), specify a certain page section, and search for each field such as a file name, page number, and address.
[0062]
The user can also infer the contents of the page file from the file name and designate a specific page file. In this case, the file name is preferably not a number as shown in FIG. 3, but a file name representing the contents of the page file.
[0063]
A designation mark is attached to the mark column of the designated page file 7i. Finally, the file names and addresses of all the page files 7i to which the designation mark is attached are stored in the server 2 as described above. It is sent (step S140), and only these page files are distributed (step S150).
[0064]
According to the browsing client server system 1 described above, when the user browses the content file 5 having a large number of page files 7i (i = 1,..., N), the index file 8 and the user truly want to browse. Only the page file 7i (i = 1,..., N) can be transmitted and received. The index file 8 has a small amount of data, and its transmission / reception time and communication load are small. Since only the page file 7i (i = 1,..., N) that the user really wants to browse is transmitted / received, the page file 7i (i = 1,. It is possible to avoid waste of transmission and reception.
[0065]
As a result, the time required for communication is shortened, and for the user, only necessary information can be browsed in a short time.
[0066]
Further, the search process of the page that the user desires to browse is performed on each client 3, and the processing is not concentrated on the server 2, so that an excessive processing load is not imposed on the server 2.
[0067]
It should be noted that a function of “page turning” can be added to the display of the page by the display means 11.
[0068]
“Page turning” is a function of continuously displaying a predetermined section of a page transmitted to the client one page at a time or a fixed number of pages. According to this function, the page file 7i (i = 1,..., N) searched by the user within a certain ambiguous range is sequentially displayed at a constant speed so that the page that the user really wants is displayed. I can find it. This function can be added to any of the embodiments described below.
[0069]
Although the description of the first embodiment of the present invention has been completed, more convenient page search can be performed by adding various information to the index data. An embodiment in the case where various information is added to the index data will be described below.
[0070]
In the second embodiment of the present invention, keywords are added as index data. The keyword is a word related to the contents of the page file for each page file and is used for searching the page file.
[0071]
In the browsing client server system according to the present embodiment, the system configuration, the flow of page search and designation are the same as those in the first embodiment except for the page search by keywords (see FIGS. 1 and 2). Therefore, only a method of searching for pages by keywords will be described with reference to FIG. In addition, the same part as 1st embodiment is demonstrated using the same code | symbol.
[0072]
FIG. 4 shows the configuration of the index data table or database formed by the index file 8 and the content operation means 10 when keywords are added as index data.
[0073]
As shown in FIG. 4, in this embodiment, in addition to the file name, page number, and address, keywords are described in the index file. As described above, the keyword is a word related to the contents of each page file, and, for example, monthly report, January, Tokyo, sales, total, nationwide, etc. The content operation means 10 is configured such that the user can input a predetermined keyword by an input means (not shown). When the user inputs a predetermined keyword, the content operation means 10 is configured to search for a keyword in the index data table or database and search for a page file having the corresponding keyword.
[0074]
The keyword search of the page file 7i (i = 1,..., N) by the content operating means 10 can be performed by combining a plurality of keywords according to AND and OR conditions.
[0075]
According to this embodiment, a browsing client server system that allows a user to search the page file 7i (i = 1,..., N) that the user desires to browse in various ways using keywords, and enables accurate and convenient page search. be able to.

In the following description, the input date and time and creation date and time will be described as representatives.
[0076]
The input date / time is data of the date / time when the page file 7i (i = 1,..., N) is subscribed to the content file 5, and the creation date / time may be the same as the input date / time. This is the date and time when the page file was created or the date and time of the information of the page file. For example, in the daily work report, two date / time data, that is, an actually created date / time and a date / time added to the content file can be used as index data.
[0077]
FIG. 5 shows a table or database of index data constituted by the index file 8 and the content operation means 10 when input or creation date / time data is added as index data. As in the above-described embodiments, the file name, page number, address, input or creation date / time data are configured to be compatible with each other.
[0078]
The browsing client server system according to this embodiment is configured such that a user can input a predetermined date and time by an input unit (not shown) of the content operation unit 10, and the predetermined date and time are input as a search condition. When this is done, the content operating means 10 is configured to search the corresponding page file from the index data table or database.
[0079]
According to this embodiment, it is possible to obtain a browsing client server system that can search for a page file 7i (i = 1,..., N) that a user desires to browse on a time axis.
[0080]

Editing operations are divided into editing of page file contents and subscription of editing information. Editing the contents of a page file refers to an editing operation for adding, changing, or deleting the contents of an existing page file or adding a new page file. The addition or addition of editing information does not directly edit the contents of the page file, but refers to an editing operation for adding a mark or inserting a separator page.
[0091]
When the user performs the above editing work, the content operation means 10 of the browsing client server system 12 of the present embodiment enters editing information related to the index data in the index data, that is, the index file (step S220). The editing information related to the index data is information indicating that a mark (mark A, mark B, etc. depending on the type) is added to a predetermined page file as shown in FIG. 8, for example. Other editing information includes, when a separator page is inserted, the insertion position of the separator page and the type of separator page, and when a new page is added, the entire index data of the additional page, its insertion position, and the existing page When editing the contents of the file, there is necessary editing history information such as editing date and time.
[0092]
In short, when the user performs some processing on the page file or the content file, the editing information can search the processed page file by searching for the processing action. As long as the editing information falls within this category, any specific editing work such as a mark or a separator page may be used.
[0093]
When the user finishes the editing work, the changed page file and the changed index file 8 are transmitted from the request unit 9 of the client 3 to the content management unit 6 of the server 2 (steps included). S230). The content management means 6 of the server 2 that has received the information on the changed file searches for the corresponding file, updates (including addition or deletion), and manages the new file.
[0094]
As described above, the editing information is used for searching the edited page file.
In other words, the page file on which the editing operation has been performed can be searched by searching the editing information item by the content operating means 10 (step S240). For example, in the example shown in FIG. 8, the file 00001.tif can be searched by searching the page file with the mark A. The search for page files based on various types of editing information will be further described below.
[0095]
FIG. 10 visually illustrates an editing operation for attaching a mark.
As shown in FIG. 10, in the browsing client server system 12 of this embodiment, a plurality of types of marks can be added. For example, in addition to a mark attached to a sentence, a sticky note attached to a page is a kind of mark. In addition, a plurality of types of marks can be attached to the marks in the sentence with different colors and patterns.
[0096]
As described above, when a certain type of mark is added to a page file, in the system of the present embodiment, the content operation unit 10 adds the mark of that type to the index data of the marked page file. Editing information indicating that is entered.
[0097]
As described above, if editing information indicating that a predetermined type of mark is added to a predetermined page of one content file is accumulated, a page with the predetermined type of mark is searched for in the editing information item of the index data. Can do it.
[0098]
According to the browsing client server system 12 of the present embodiment, the content processed by the user can be searched according to the type of processing, and free and multifaceted use can be expected.
[0099]
FIG. 11 visually illustrates an editing operation when a separator page is inserted.
[0100]
As shown in FIG. 11, the browsing client server system 12 of this embodiment can insert a separator page between existing page files. This separator page is inserted mainly for the purpose of dividing the content file into chapters, has a tag, and can also give a name to the separator page.
[0101]
Further, the separator page can be a separator page with a hierarchy as shown in FIG. A “separated page with a hierarchy” refers to a separator page having a size or level of a separator such as chapter, section,.
[0102]
When a separator page is inserted into the content, if the page is inserted between the apparent pages 1 and 2 at the corresponding position by the content operation means 10, for example, the apparent 1.5th page, Editing information related to the name and hierarchy information is written in the index data.
[0103]
In this way, if editing information in which a predetermined type of separator page is inserted in one content file is accumulated, a separator page with a predetermined name is searched for in the edit information item of the index data, or a predetermined separator page is stored. The page file of the section can be searched. Note that the text page in the content can be used as a separator page.
[0104]
According to this browsing client server system 12, the content that the user has divided into chapters can be searched by the separator page and the section of the separator page, and free and multifaceted use can be expected.
[0105]
Also, according to the browsing client server system of the present invention, a clip function can be added to the editing means 13. The clip function is a function for attaching a virtual clip that groups a plurality of apparent pages of a content file as a group. By attaching virtual clips to a plurality of apparent pages of the content file, the pages are grouped. Grouped pages can be searched or flipped together. By grouping pages with the same content, it is possible to quickly grasp the content of the content file. It is also possible to send only page files of the same group from the server.
[0106]
The editing unit 13 can add a new page file at a predetermined position on the existing page file array. In this case, a new page file is created by an input means such as a scanner or a keyboard, and is transmitted to the server 2, and is inserted into the corresponding position by the content operation means 10, for example, between the apparent pages 1 and 2. If it is, the additional page file index data is inserted as if it is the 1.5th page, the changed index file is transmitted to the server 2, and the existing index file is updated.
[0107]
When a new page file is added, editing information indicating that the page file is the added file can be added to the index data. Moreover, the data of the added person can also be added. Thereby, only an additional page can be browsed.
[0108]
In addition, in a system for adding and editing a new page file, an “insert” function can be added.
The “insertion” function is a function that takes in a page file created by other existing software and edits it using the software.
[0109]
When adding a new page in a system with an “insert” function, the data is added to the content file in the file format of other application software, and is expressed by the control code of the application software as necessary. Add image data as image data.
[0110]
When editing the additional page, the editing unit 13 starts up other application software and allows the user to edit it, and updates the corresponding file as the file format and image data of the application software again after the editing. .
[0111]
According to the system having the “insertion” function, information created by existing software can be used, and a browsing client server system for a wide range of uses can be constructed.
[0112]
Finally, an embodiment in which page files constituting one content file are stored in a plurality of servers will be described.
[0113]
FIG. 12 shows the configuration of the browsing client server system of the above embodiment. In this figure, for the sake of easy understanding, the same parts as those in FIG.
[0114]
As shown in FIG. 12, in the browsing client server system 14 of this embodiment, page files constituting one content file are stored in a plurality of servers. It should be noted that the “one content file” here is an apparent one content file, not a file handled by a computer.
[0115]
That is, the address of the location where each page file is stored is entered in the index file 8 of one apparently content file. The page file is stored in a plurality of content files (5a,..., 5f) of a plurality of servers (2a,..., 2n) on the computer.
[0116]
In the browsing client server system 14 of this embodiment, when there is a browsing request from the request unit 9 of the client 3 to the content management unit 6 of the server 2a, the index file 8 is sent to the client 3 by the content management unit 6.
[0117]
As described above, when the user designates a file desired to be browsed using the index file 8, the content management means 6 of the server 2a converts the designated page file to each server (2a,..., 2n) from the content files (5a,..., 5f) and transmits them to the client 3. The operational effects of this embodiment are not different from the browsing client server system of the above embodiments. Furthermore, by specifying the type of information collected by the server, a more extensive information utilization system can be constructed.
[0118]
【The invention's effect】
Thus, according to the “browsing client-server system” of the present invention, the efficiency of information use and communication is high, and the load can be reduced on both the client and the server.
[0119]
That is, for the user, data that the user really wants to browse can be received from the content file having a huge amount of data, and the desired information can be immediately accessed in a short transfer time.
[0120]
In addition, the client is not required to have a storage capacity for temporarily storing an enormous amount of data, and the burden on the hardware is small.
[0121]
In addition, according to the present invention, processing such as a search for a page file required by the user is performed by the client, so that the above processing is not concentrated on the server and added excessively.
[0122]
Furthermore, since only the file of the page required as a result of the search is transmitted, the load on the communication network can be significantly reduced.
