For example, an index can be defined as an index data set by extracting meaningful keywords from a document included in a document collection, and then indexing data on the appearance frequency, appearance position, and appearance document in an index word and sorting the data by indexes to be.

And, 'index volume' can refer to the index data set which is the final result through the indexing process.

1 is a diagram for explaining the overall configuration of a cloud disk-based personalized data retrieval system in an embodiment of the present invention.

A cloud service 101 is coupled to a network via a network interface (not shown) and is capable of communicating with a user terminal 102 coupled to the network.

The cloud service 101 may store personalization data in a cloud server 103 in a communication environment with the user terminal 102 or may edit the personalization data stored in the cloud server 103, Lt; RTI ID = 0.0 > 103 < / RTI >

The cloud server 103 refers to a server group (CS) that groups a plurality of data servers (not shown) together and operates as if they were one computer. At this time, the data server may be one of the triple servers of the cloud server as individual servers included in the cloud server. Hereinafter, a triplicated cloud server in which three servers are combined and used as one server will be described as an example.

The cloud server 103 has a plurality of data servers as a unit and has the same data in a disc, and can write / read / modify data through the CS API, which is an application program interface (API). At this time, the CS API serves as an interface for requesting the cloud service 101 to perform a computing task. When the cloud server 103 requests the cloud service 101 through the CS API, the cloud server 103 selects one specific data server among the plurality of data servers through the API program, and performs a CPU operation and a disk operation from the computer .

The index request control server 104 controls the indexing process of the personalized data according to the index request of the cloud service 101. [ The index request control server 104 may assign personalization data for each user to a specific data server by using the CS API to control the index to be assigned by the data server. At this time, the cloud service 101 can request an index on the personalization data when the user terminal 102 logs in or an indexing event occurs due to a request such as creation, editing, movement, or deletion of personalization data.

The search API (application program interface) server 105 requests the search server 106 to search according to the search request of the user terminal 102 through the cloud service 101 and searches the search server 106 for search results And returns it to the cloud service 101.

The search server 106 is a search execution subject for searching personalized data stored in the cloud server 103, and may be implemented as a system independent from the cloud server 103.

In particular, the search server 106 may access the disk of the cloud server 103 directly via the file access system 107. At this time, the file access system 107 is based on a file system implemented by the cloud server 103 and acts as a relay for allowing the search server 106 to access the file system.

Referring to FIGS. 2 and 3, an indexing process of cloud disk-based personalization data according to an embodiment of the present invention will be described.

When the index request control server 104 receives an index request related to the user terminal 102 from the cloud service 101, it searches the cloud server (CS) 103 to which the user ID belongs through the CS API (S31). Since the personalization data is contained in a specific cloud server (CS) 103, a process of searching for the cloud server (CS) 103 containing the data of the corresponding user ID through the CS API is required.

The index request control server 104 is connected to any one of the data servers DS constituting the cloud server (CS) 103 to which the user ID belongs, for example, the data server DS having the smallest load, (S32).

The index request control server 104 may request an index to the data server DS selected in step S32 (S33). In other words, the index request control server 104 stores the index request received from the cloud service 101 as a queue in the database DB. In the cloud server (CS) 103 to which the user ID belongs It is possible to request an index to the data server DS by allocating a data server DS having the smallest load to the queue.

The data server (DS) selected from the index request control server (104) retrieves the index job assigned from the queue of the index request control server (104) and performs an index operation using the personalized data stored on the disk The index volume generated through the index operation can be distributed to all the data servers DS in the cloud server (CS) 103 to which the user ID belongs via the CS API (S34).

Accordingly, in the present embodiment, the cloud server (CS) 103 containing the personalization data of the user ID is searched and the data server DS having the most room in the cloud server (CS) 103 is selected and the personalization data To perform the indexing.

Referring to FIG. 2 and FIG. 4, a process of searching for cloud disk based personalized data according to an embodiment of the present invention will be described.

When the personalized data stored in the cloud server (CS) 103 is directly retrieved from the cloud server (CS) 103, the management of the search for the cloud server (CS) 103 must be continued.

First, when receiving a search request of the user terminal 102 from the cloud service 101 through the search API server 105, the cloud server (CS) 103 searches the data server DS to which the user ID belongs via the CS API (S41).

At this time, the cloud server (CS) 103 can generate a configuration file for searching the selected data server DS and distribute it to the search API server 105 and the search server 106 (S42 ).

The search API server 105 may request the search server 106 to search the search request of the user terminal 102.

When the search server 106 receives the search request of the user terminal 102 from the cloud service 101 via the search API server 105, the search server 106 searches for the user ID 102 based on the configuration file distributed by the cloud server (CS) The search can be performed using the data server DS to which the mobile terminal belongs.

At this time, the search server 106 accesses the disk of the data server DS to which the user ID belongs through the file access system 107, and reads the index volume stored in the disk of the corresponding data server DS to perform the search (S43). The search server 106 can open the index volume of the path in real time by creating a symbolic link in real time on the search standard path for the index volume stored on the disk of the data server DS to which the user ID belongs .

In other words, the search server 106 loads the index volume stored in the disk of the data server (DS) to which the user ID belongs at the moment of starting the search, and performs the search, and sends the search result to the search API server 105 And returns it to the cloud service 101.

The cloud service 101 receives the search result from the search server 106 through the search API server 105 (that is, a result obtained by using the index volume stored in the data server DS to which the user ID belongs) (Highlighting, passages, etc.) (S44).

Since the data stored in the cloud server (CS) 103 has a very large capacity, the entire data can not be retrieved in the memory. In this embodiment, a configuration file is created and distributed to perform a search for a specific data server DS at the moment of starting a search, and the search can be performed by placing an index volume stored in the data server DS in memory.

The above-described cloud disk-based personalized data retrieval method may include more shortened operations or additional operations based on the details described with reference to FIGS. In addition, more than one operation may be combined, and the order or location of the operations may be changed.

[ For example, the memory 501 may be a hard disk, an SSD, an SD card, and other storage media.

The interface unit 502 may support an interface between the search server and the search API server and an interface between the search server and the cloud server in order to search personalized data stored in the cloud server.

The processor 500 is an apparatus for processing according to instructions of a program stored in the memory 501, and may include a microprocessor such as a CPU. The detailed configuration of the processor 500 is as follows.

When the cloud server receives a search request of the user terminal from the cloud service through the search API server, the cloud server searches for and selects the data server (DS) to which the user ID belongs through the CS API, The file can be created and distributed to the search server.

When the access unit 510 receives the search request of the user terminal from the cloud service through the search API server, the access unit 510 accesses the data server DS to which the user ID belongs based on the configuration file distributed by the cloud server CS, Lt; / RTI > At this time, the access unit 510 can open the index volume of the path in real time by creating a symbolic link in real time as a search standard path for the index volume stored in the disk of the data server DS to which the user ID belongs.
