The present invention relates to a file management system, and more particularly, to a file management system that enables each client to share and search each other's files by field, by mutually searching and using files of each networked client.

Many clients (eg, personal computers, laptops, PDAs, etc.) distributed in universities, national and corporate research institutes store the research results of each researcher who runs the client in the form of a file. These files are stored in a specific folder (for example, "My document" folder) under the researcher's control, and in the case of files created by programs in the electronic and mechanical fields, the files generated by the program are not included in any of the folders that constitute the program. Often stored in one folder. In addition, in the case of a company mainly for paper work, the files generated by the terminal of each office worker are stored in a folder determined by the office worker. This file management method does not have a big problem in managing and using files for each individual, but it is difficult to share files created by each individual with others. Of course, there is a method of providing a file server in a company or a research institute and sharing a file of each individual through the file server, but this is a problem that can be shared only when each individual registers a file in the file server. There is. In particular, in the case of researchers working in research institutes, many researchers conduct research on a common research topic, and data (files) can be obtained only by requesting data (files) from other researchers. At this time, the researcher who requested the data does not know what the other researcher has.

Accordingly, an object of the present invention is to provide a file management system that enables each individual client to mutually search for files of other clients and classify the searched files by subject to enable file sharing for each individual. Another object of the present invention is to provide a file management system for extracting files from each networked client, classifying the extracted files according to a predetermined classification criteria, and then searching and sharing them with each client. In providing.

According to the present invention, the above object is network-connected with at least one client, a file search unit for searching files provided in each client, and indexing each searched file according to at least one field, and the searched file. And a file database for storing the data according to the field index setting, wherein the file search unit provides the client with a list of files corresponding to the search request in response to a search request from the client, and the client provides the file list. When selecting a desired file in the, it is achieved by a file management system to call the corresponding file in the file database and provide.

Advantageously, further comprising an index database having a unique identifier for each retrieved file in accordance with said index setting.

When a search request is generated from the client, the file search unit provides the client with a file list corresponding to the search request by referring to the index database, and when the client selects a desired file from the file list, It is desirable to provide a file to be called from the file database.

The file search unit preferably indexes the file based on the file extension and the words included in the file name.

It is preferable that the file search unit performs word extraction through morphological analysis on the file name and indexes the extracted word based on the extracted word.

The client is provided with a manager program for accessing the classified file for each sector, and searching for files in the file database for each sector through the manager program.

The file search unit indexes a file collecting module for collecting files from each client and a file collected by the file collecting module, and searches for a corresponding file among the indexed files in response to a search request from the client. A file search unit for generating a file list for the file, and communicating with the manager program installed in each of the clients, providing a search request through the manager program to the file search unit, and providing a file list corresponding to the search request. It is preferable to include a search module for receiving from the search unit and providing it to the manager program.

Preferably, the apparatus further includes a search robot that periodically visits a website and extracts a document file from the website.

The file database may include files stored in the clients and files extracted from the website for each of the fields.

The above object includes at least one client and a file server network-connected with the client, the file server indexing and storing a file retrieved from each client, wherein the client is connected to the other network through the network. A file search module for searching the client by a search word and registering the searched file in a predetermined tree-shaped directory, wherein the file searched by the file search module is registered by a file search system registered in the file server. Is achieved.

The file retrieval module is preferably installed in each of the clients, and can set the tree-shaped directory structure differently for each client.

Preferably, the file server further comprises a search robot that collects files from a website connected via the network.

Preferably, the file server includes a file database including a file provided from each client, an index database including index information of a file collected through the search robot, and a file corresponding to the index information. .

According to an embodiment of the present invention, a file search unit for searching a file included in each of the at least one client and classifying the searched file by applying an index criterion provided for each of the searched files; An index database having a unique identifier for a file, and a file database for storing each indexed and classified file, wherein the file search unit refers to the index database when a search request is generated from the client; It is achieved by a file management system that provides a file list corresponding to a search request to the client, and when the client selects a desired file from the file list, calls the corresponding file from the file database and provides the file.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a block diagram of an example of a file management system according to the present invention.

The illustrated file management system includes a file search unit 201, an index database 202, a database (DB) 203, and a search robot 204. The file retrieval unit 201 collects files stored in a storage medium (for example, a hard disk drive) of each client (for example, reference numeral “100”, hereinafter omitted). At this time, the file collection of the file search unit 201 may be performed by the following method.

1) The file search unit inquires and collects files of each client every predetermined period (for example, several minutes to several hours).

2) A method of installing a manager program for file management in each client and obtaining and collecting file information newly generated by the installed manager program.

When the file search unit 201 collects files by the method of 1), the file search unit 201 accesses each client at a predetermined time, searches for files, and collects newly created or modified (deleted) files. . In this case, the file search unit 201 classifies and indexes files collected from each client and provides the index to the index database 202. Classification of the collected files is performed by referring to words and extensions included in the name (or contents) of the file. In addition, the file search unit 201 may perform word extraction through morphological analysis on the name of the file and classify the file through the extracted word. For example, if the name of the file is "What is ubiquitous.pdf", the noun "ubiquitous" is extracted from the file through morphological analysis of the file name, and the classification is performed according to the extracted noun. If such a collection of files is made in a laboratory, the file (what is ubiquitous.pdf) may be considered to be a file in the ubiquitous technical field. When the file retrieval unit 201 collects files by the method of 2), the file retrieval unit 201 collects files by receiving newly generated or changed file information from a manager program installed in each client. In this case, the file retrieval unit 201 does not need to retrieve the file stored in the storage medium of each client at predetermined intervals.

The index database 202 stores index information for each file collected by the file search unit 201. Index information includes unique identifiers representing each file instead of the full information for each file. This will be described with reference to FIG. 2 together.

2 is a diagram for conceptually describing a method of indexing a file including a name. As shown, in the case of a file containing a name, when the names are classified by name, the names with the last name of Kim, Kang, Gam, and Kum are given to "ㄱ", and the names with Na, old name are "B". Can be classified as Kim's surname is indexed by being classified into a "b" field, the file search unit 201 can immediately find this by searching only the "a" field when searching for a name with Kim. With the same tips, the same can be applied to surnames corresponding to b-ㅋ. In this sorting by indexing, the file searching unit 201 classifies a file containing a person's name into a field of a to ㅋ and stores it in the index database 202, and responds to a search request from a client. The search speed of the file search unit 201 may be improved by searching the file through 202. On the other hand, the files classified according to a ~ will have a unique identifier, respectively, A1 to A3 is illustrated as a unique identifier in the figure. The unique identifiers (for example, A1 to A3) are representative values corresponding to the files stored in the database (DB) 203, and the file search unit 201 can immediately access the files stored in the database (DB) 203 using them. Can be. Accordingly, the file search unit 201 searches for a field stored in the index database 202 when the search request for the name having the last name from the client is received, and index information of the file including the name (eg, A1). And the file corresponding to the index information A1 is accessed from the database 203 and provided to the client. Although FIG. 2 has been described with reference to a user's name that is easy to understand and explain in order to explain how to perform an index, indexing of a file may include technical terms, file creator, file creation date, update date, It can be indexed by various criteria such as file extension and file modification. 2 is only one of these various criteria, and the invention is not limited thereby.

On the other hand, the indexing method described with reference to FIG. 2 may include a method of using a name included in a file name or a method of indexing for each technical field. For example, if one of the research institutes of the research institute is a "mobile phone", based on a mobile phone, "RF" (Radio Frequency) mounted on the mobile phone, "DSP" (Digitl Signal Procssor) mounted on the mobile phone, and "folder" A file including a technical term, or a file name may be provided by matching a search word of a mobile phone. Here, the description term included in the file may be a file name of the file, but may be obtained through text included in the file. This will be described later in detail.

Figure 3 shows a block diagram of another embodiment of the present invention.

The illustrated file management system is similar to that shown in FIG. 1, but has a file retrieval unit 201 and an index database 206 embedded in each client. Accordingly, each client is connected to the file server 205 through a network, and the files searched and shared with each other are provided to the file server 205 and stored. To this end, each client is provided with a manager program having a function of searching for a file provided to another client, providing a result to a user of the client, and providing a file provided to the file to the file server 205. . The manager program can form a search tree for each user of the client, and can obtain a desired search result through each search tree. This will be described with reference to FIGS. 4 and 5 together.

4 illustrates an example of a main interface screen of a manager program executed on a client.

The illustrated manager program includes an integrated search, thesaurus search, terminology search, FAQ search, ontology search, My search, and management menu. Each menu is summarized as follows.

1) The integrated search shows a menu for searching both web search and files provided in each client. The integrated search retrieves all documents containing the search term entered by the searcher in the manager program and displays the list for the user. Here, the search results according to the integrated search menu may be sorted according to accuracy, registration date, source, and file format.

2) Thesaurus search refers to a search menu that provides searchers with results that include words associated with a search word. This will be described with reference to FIG. 5 together. As shown in FIG. 5, when a searcher enters the search word "peritoneum" in the manager program and requests a file search for the file, the search result is a word including "peritoneum" and a word associated with "peritoneum" (eg, abdomen, Peritoneal cavity, peritoneal cavity, membrane, laparoscope, etc.). This search method is useful when the searcher does not know the exact file name or has only the concept of the file to be searched. For this purpose, although not shown in FIG. 1 and FIG. 3, information on the relation between these words (eg, "peritoneum" and "veil") is provided inside the file search unit 201, or the file search unit 201 is provided. It is preferable to further include a database for providing association information of these words.

3) The term search displays a glossary of dictionaries and related vocabulary corresponding to the search word entered through the manager program. Frequently Asked Question (FAQ) search refers to a search function for an Internet document or a file in which a query is answered. In general, in order to view the FAQ document through the Internet, the manager program should search the Internet document or file collected through the search robot 204. The index information for Internet documents or files collected by the search robot 204 is stored in the index database (DB) 203, and the files or Internet documents are stored in the database (DB) 203, so that the manager program is a file server. Through 205, Internet documents or files stored in the database (DB) 203 are obtained.

4) Ontology search searches the words semantically related to the search word for the search word entered by the searcher through the manager program and provides the searcher with the result. For example, if the search word is "immunology", since the search word is related to medicine, the file search unit 201 searches a file for medicine, immunology, and "serumology" having a high correlation with immunity and medicine.

Meanwhile, the ontology search method may be implemented through the file search unit 201 illustrated in FIGS. 1 and 3, but may be implemented through a separate search module connected to the file search unit 201 or having a relevance to a search word. It can be implemented through a database with information. Hereinafter, the ontology search will be described with reference to FIG. 6.

6 illustrates an example of a search result by ontology search and an interface screen corresponding thereto. When the searcher selects "Ontology Search" from the main menu and enters the search term "protein", the searcher enters the file containing the search term "protein" among the files included in each client of the search term ("C-reactive protein") and By displaying the search results files and their interrelationships for similar files (eg, "Activation", "reactant", "sub_class_of" in the drawing) and listing them in a tree structure, it makes it easier for searchers to find what they are looking for. Make sure

7 and 8 illustrate examples of interface screens for extended search and cluster search, respectively.

First, FIG. 7 illustrates an extended search interface screen displayed on a screen when a searcher presses an extended search key (not shown) provided on one side of files searched by a search word. As shown, the extended search extracts words constituting the file from the file selected by the searcher and re-performs the searched word again, thesaurus search, terminology search, and ontology search. The words that make up the file selected by the user in the drawing include "direct", "ubiquitous", "introduction", "existence", "latin", "computon" ..., and "online". After selecting one of these items, you can rescan the selected word. If there is a word among the above words that the searcher wants to know the term meaning, the searcher can select the "Terminology" tab and get an answer.

8 shows an interface screen for clustering search. As shown, the clustering search groups together categories that are semantically similar to the search results. In the drawing, when the search word is "Internet", even though the Internet is not included, the searcher is provided with a file for "Ubiquitous.doc" and "License.txt" for the Internet license.

9 illustrates an example of an interface screen displaying a distribution of words included in a file selected by a searcher among files searched by the searcher.

As illustrated, the searcher may select any one of the files searched for the search word and classify the description type of the corresponding file through distribution of words included in the selected file. To this end, the search unit 201 may extract a word for each of the collected files, and calculate a frequency of distribution of the word by referring to a predetermined technical classification table for the extracted word. A technical classification table refers to a classification table for concepts mainly shared by the Internet, wireless communication, health, and other research institutes or company organizations for word-gathered data such as electronic dictionaries. Here, the search method illustrated in FIGS. 7 to 9 may be implemented by installing a program module supporting the thesaurus search, ontology search, terminology search, and integrated search in the file search unit 201. 201 may be implemented in conjunction with the file database 203 storing the files collected by each client and the index database 202 for the file database 203.

10 illustrates an example of an interface screen for forming a knowledge map for each client by using a manager program in which each client connected to the file management system is installed.

As shown, the manager program installed in each client may form a directory ② by each searcher or technical field by a searcher. In the figure, the top-level directory is the "knowledge map", and the directories are shown below in the order of "health care", "organ", "technology", "food and ingredients", and "chemicals and drugs". have. Each directory may be arbitrarily created and deleted by a searcher, and each directory may search for and register a file according to a search formula set by the searcher, or a file arbitrarily selected by a searcher may be registered. This directory structure allows the searcher to find the desired file easily, and allows the searcher to selectively search only the desired file.

As described above, the present invention enables each individual client to mutually search for files of other clients and classify the searched files by subject to enable file sharing for each individual. In addition, the present invention may provide a variety of information required by the searcher by searching for information associated with the search word and providing the searcher in addition to a search corresponding to a single search word.
