In addition, by expressing detailed information of a search result according to a user's request, information can be clearly provided to the user.

The configuration of the portable terminal and the online search service system according to the preferred embodiment of the present invention is as shown in FIG.

The portable terminal H includes a control unit 100, a user interface unit 112, an external device interface unit 114, a memory unit 118, an output unit 126, a display 134, a speaker 136, and a mobile device. An external memory device 116 may be additionally connected to the portable terminal H.

The controller 100 controls the portable terminal H as a whole, and particularly, the metadata generation engine 102, the metadata management engine 104, for a search function according to an exemplary embodiment of the present invention. It is equipped with various software modules including search engine 106, result processor 108, and execution processor 110.

The metadata generation engine 102 extracts metadata from the raw data of the raw data 120 and provides the metadata to the metadata management engine 104.

The meaning of the metadata is expressed by the term attribute, which clearly expresses some information so that it is distinguished from other information. In general, the metadata is described as "data of data". do.

The raw data 120 may store various types of raw data, and the raw data may include PIMS (Personal Information Management System) information including menus, document files, multimedia files, content files, and phone books for processing functions. It may be data of all entities that can be requested by the user, such as message information and call logs.

The metadata generating engine 102 detects the type of raw data, extracts data of fields set differently according to the type of raw data, and configures meta data, or extracts semantic information. Organize your data.

This will be described in more detail with reference to FIG. 2.

Among menu items, menus, document files, multimedia files, messages, contents, and games, fields such as a name, a storage path name, and a keyword of HELP are set as metadata fields. In the case of a content file, there are various types of files. Therefore, different fields are set as metadata fields according to the type of each file. For example, in the case of an MP3 file which is an audio file, fields such as a file name and tag information are set as metadata fields. In the case of a JPEG file which is an image file, fields such as file name and EXIF information are set as metadata fields. Is set.

For downloaded files or files provided from the mobile storage, a field such as a file name is set as a metadata field. The files may be a ring tone file or a wall paper.

The PIMS information such as a task, calendar, memo, or the like, or all of the designated fields are set as metadata fields.

In the phone book, fields such as name and phone number are set as metadata fields, call log data is set as fields such as telephone numbers and callers as metadata fields, and browser book marks are strings, protocols, and created times. The field for etc. is set as the metadata field.

In the online search result, specific tag information, a document name, a protocol, and the like are set as metadata fields in an XML document.

In addition, a message such as a short text message (SMS), a multimedia message (MMS), an email (Email), and the like extracts semantic data of information and stores it as metadata, and a method of extracting semantic data from the message is shown in FIG. 3. It will be described with reference to.

The metadata generating engine 102 extracts semantic data through a parsing process and / or a summary process for the message among the raw data.

The parsing process parses the header and body words of the message to extract important information. In the case of e-mail, important words are generally bold, font color, and word size. In the parsing process, text having different bold or different colors or different sizes is extracted. In addition, in the case of a message having a field, data of a main field is extracted. The main fields may include a title, a sender, a recipient, a name and type of an attached file, and an index word input by a user.

In addition, the summary process is a function of performing a lexical analysis, and in the case of meaningful words, since the statistics tend to be statistically repeated, the main vocabulary repeated from the text is extracted and the extracted main vocabulary is extracted. The metadata may be generated by summarizing the text, or generating the metadata by abstracting the text by extracting a sentence including a predetermined vocabulary.

As described above, the meta data generation engine 102 generates the meta data with the data of the fields differently set for each kind of the raw data 120, or extracts semantic information from the raw data 120 to generate the meta data. Generate data.

Meta data configured as described above has a high search accuracy but takes a lot of time compared to a simple method of extracting a vocabulary, and according to the present invention, it is employed in MD5 (MESSAGE DIGESTION ALGORITHM 5) of cryptography to improve the efficiency of the search. Speed up the search by using the Digestion method. The MD5 is described in RFC 1321 in the Internet Intercepting Force Forum (IETF).

In the present invention, a method of expressing a keyword as a small number of bytes through a hash function (HASH FUNCTION) improves the efficiency of the search by finding a digested keyword through a constant search instead of a string when searching. For example, "South Korea" retrieves a string through a function that converts to 12345 "and the terminal" 5234. "Considering the case where different strings are mapped to the same string of numbers, it is appropriate for information engineering. Adopt a filtering technique.

As described above, the meta data generated by the meta data generation engine 102 is managed by the meta data management engine 104 by the meta data DB 122. The meta data management engine 104 converts meta data into a meta data format and registers (creates) the meta data in the metadata DB 122, and at the request of the user through the user interface unit 112, the meta data DB 122 Delete or modify the metadata registered in the C) and enable the search of the metadata DB 04 in response to a request of the search engine 106. In addition, the metadata management engine 104 updates the frequency of use / rate of the metadata in accordance with the information on the frequency of use of the metadata provided from the result processor 108.

In addition, the metadata management engine 104 may store metadata input by a user through the user interface unit 112 in the metadata DB 122.

As shown in FIG. 4, the meta data stored in the meta data DB 122 has fields such as type, category, keyword, probability, creation time, and link. The type item stores information such as the type and name of metadata, the category item stores type information of the content, and the keyword item includes data of a field extracted from corresponding raw data for use in a search. The frequency item stores the frequency of use and the rate at which the metadata is selected and executed, and the time information about the time at which the metadata was generated or updated is stored in the probability item, and the execution item is stored in the link item. Or bookmark information is stored.

The search engine 106 searches the metadata corresponding to the search term requested by the metadata DB 122 according to a user's search request through the user interface 112, and searches the result of the search result data DB. In addition to the information stored in 124, the result processing unit 108 is provided.

In addition, the search engine 106 may perform the online search by connecting to the search service server through the switch or proxy server through the mobile communication function unit 138. The search engine 106 stores the search results in the search result data DB 124 and provides them to the result processor 108 when the online search results are provided in the format of metadata through the conversion or proxy server. When the online search result is provided in an XML format, the online search result is converted into a metadata format and stored in the search result data DB 124 and provided to the result processor 108.

As described above, the present invention stores the search results in the search result data DB 124, thereby enabling to implement a favorite function.

The result processing unit 108 provides search results stored in the search result data DB 124 according to a search result provided by the search engine 106 or a user's request to perform a bookmark function through the user interface unit 112. Receives the processed form to the user and outputs through the display 134 and / or speaker 136 through the output unit 126.

For example, the portable terminal H guides the contents in the form of a list, so that the search results can also be guided in the form of a list, and the processing of the search results may include the priority of the list and the sorting of the list by items. Can be. That is, if there is a statistical record of mainly searching and executing the MP3 file, the MP3 file may be set to a higher priority, or the type of the last searched content may be set higher. Also, the guide item may be set differently according to the content and the searched keyword. That is, if a search is performed by a person's name, the phone book may indicate a phone number, and in a call log, a message such as a time of call or an e-mail may indicate a title of a message transmitted and received with the person. The object stored in the favorites can be the entire search result list and some of the items in the list. There is a save function in the list, which deletes the saved list from the list, converts the name of the saved list, and reloads the saved list.

In addition, the result processor 108 may increase the convenience of the user by dividing the search results into pages for each category.

When the execution processor 110 is commanded to execute one of the search results guided by the result processor 108 in the form of a list through the user interface unit 112, the meta data is linked using the link information of the corresponding metadata. Load and execute the source file according to the data. For example, when the item requested to be executed is a menu, an operation according to the menu may be performed to perform a role as a shortcut for the menu. When the item requested to be executed is an MP3 file, a media file. To play the selected MP3 file through the audio processing and output unit. If the requested item is a bookmark and an online search of a wireless internet browser, the wireless internet browser is activated to perform a wireless Enable internet service.

The user interface unit 112 is responsible for the interface between the user and the control unit 100.

The external device interface unit 114 provides an interface with an external memory device 116, such as a SD (SECURE DIGITAL) memory device or a SIM card, and provides data from the external memory device 116 to the controller 100. In addition, data from the controller 100 is provided to the external memory device 116.

The memory unit 118 provides a processing program of the controller 100 and a memory area according to the operation of the program, and in particular, the raw material 120, the meta data DB 122, and the search according to a preferred embodiment of the present invention. The result data DB 124 is provided.

The output unit 126 is composed of a graphics processing and output unit 128, a video processing and output unit 130, an audio processing and output unit 132, the graphic processing and output unit 128 is the control unit ( The graphic display data according to the control of 100 is processed and displayed on the display 134, and the video processing and output unit 130 processes the video data according to the control of the controller 100 to display the display 134. The audio processing and output unit 132 processes audio data according to the control of the controller 100 and outputs the audio data through the speaker 136.

The mobile communication function unit 138 is in charge of a general mobile communication function under the control of the control unit 100, as well as a request for searching according to the present invention by accessing a switch or a proxy server or a search service server through a wireless network. And receiving a search result.

When a search request is generated through the portable terminal H, the switchover or proxy server requests the search according to the request of the portable terminal H by accessing the search service server, and the search service server according to the request. When the search results are provided in the XML format, the search results of the XML format are converted into the metadata format according to the present invention and provided to the portable terminal H.

In addition, the conversion or proxy server may store the search results for a plurality of search words in advance, and when the search for the search words is requested, the stored search results may be provided to the portable terminal to reduce the online search time. In addition, the switching or proxy server transmits an error signal to the corresponding portable terminal if the search result is not provided from the online search site within a predetermined time, thereby reducing the waiting time for the user.

Now, the operation of the portable terminal H configured as described above will be described in detail.

First, the meta data generation method will be described with reference to FIG. 5.

The controller 100 starts a process for generating metadata when an event such as storing new raw data occurs (step 200).

When generation of the raw data is requested, the controller 100 detects the type of the raw data (step 202). When the type of the raw data is detected, the controller 100 determines whether the type of the raw data is a message to generate meta data by extracting semantic data (step 204). If the raw data is not a message, the controller 100 extracts data of fields preset according to the detected type as metadata (step 206).

Unlike the above, if the raw data is a message, the controller 100 generates meta data by extracting semantic data from the message through parsing and / or summarizing the raw data, which is the message (step 208). .

When the metadata is obtained as described above, the controller 100 performs a hash function conversion on the metadata to convert the data of the string into a constant string, thereby reducing the amount of data and improving the search speed. (Step 210).

Now, the meta data management method will be described with reference to FIG.

The metadata management engine 104 of the controller 100 checks whether metadata is received from the metadata generation engine 102 or the user interface 112 (step 300). When the metadata is received, the controller 100 processes the received metadata according to the metadata format and stores the metadata in the metadata DB 122 (step 302).

The metadata management engine 104 of the controller 100 confirms which execution information on which metadata is provided from the result processor 108 (step 304). When the execution information for any one metadata is received, the metadata management engine 104 updates the usage frequency / rate of the metadata (step 306).

In addition, the metadata management engine 104 of the controller 100 checks which metadata is requested to be deleted or modified through the user interface 112 (step 308). When the deletion or modification of any one of the metadata is requested, the metadata management engine 104 of the controller 100 performs the deletion or modification on the metadata requested to be deleted or modified (step 310).

Now, a search method according to a preferred embodiment of the present invention will be described with reference to FIG.

The search engine 106 of the controller 100 checks whether a search is requested through the user interface 112 (step 400).

When the search is requested, the search engine 106 of the control unit 100 checks whether the user requests an online search (step 402), and the user searches for the data of the portable terminal H instead of the online search. Upon request, the search engine 106 of the controller 100 displays a search word input window and waits for a user to input a search word (steps 406 and 408). When the user requests an online search, the control unit 100 proceeds to step 404 to perform a predetermined online search operation according to the present invention.

When a user inputs a search word in the displayed search word input window, the search engine 106 of the controller 100 searches for metadata corresponding to the input search word among metadata stored in the metadata DB 122 (410). Step), the search result is stored in the search result data DB 124 and provided to the result processing unit 108. The result processor 108 outputs a plurality of metadata provided as the search result to the display 134 through the output unit 126 (step 412).

Here, since the meta data stored in the meta data DB 122 is converted into a constant string through a hash function conversion, the search engine 106 converts a search word input to the search word input window into a hash function and then converts the search word. By searching the meta data corresponding to the search, the search efficiency can be improved.

In addition, it is obvious that the output unit 126 restores and displays the hash function converted metadata.

An example of displaying a search result by the output unit 126 will be described with reference to FIG. 8. 8 is a screen in the process of inputting a phone number to make a call. As shown in FIG. 8, the search results are displayed in the form of a list, and the priority of the list depends on the frequency of use / rate, the category of raw data executed by the user, or the raw set by the user. It depends on the category of the data. In particular, when outputting the search result, a part or all of the meta data is additionally displayed, so that the user can easily identify the data he / she wants to find.

During the display of the search result, the controller 100 checks whether a detailed search is requested in the input process through the user interface 112 (step 414). When a detailed search within the search result is requested according to an option set by the user, the controller 100 displays a search word input window and waits for a user input of the search word (step 416).

When a search word for the detailed search is input, the controller 100 extracts and guides a search result corresponding to the input search from the search results (step 420).

In further detail, the present invention applies a trie structure to the data structure of computer engineering for a quick search in a detailed search. The tri structure is a type of tree structure, which is an effective data structure when implementing a dictionary or the like as a data structure in which a child node is determined by a value at each node of the tree. Therefore, it is suitable for the metadata DB 122 and the search result data DB 124. In addition, in the mobile terminal (H), since the number of buttons is limited, it is very difficult to enter a large number of words from a small number of buttons. Perform a quick search.

In the example illustrated in FIG. 9, when abc1 and abd are stored in the phone book, when the user inputs a (500), the tri-structure 502 is searched for and both abc1 and abd appear in the list. If the user inputs ab (504), the tri structure 506 is searched to display abc1 and abd in the list. When the user inputs abc (508), only one path from two paths is found and the search result 512 is valid. In addition, even when the user enters abd, only one path from two paths is found and the search result 516 is valid.

The tri structure as described above is a valid data structure when the distribution of words is gathered in a specific word, such as the name of a telephone book, due to its efficiency. Therefore, it is suitable as a structure of metadata of contents such as a phone book.

As described above, while displaying the search result or the detailed search result, the control unit 100 confirms which one of the displayed search results is focused through the user interface unit 112 (step 422), and displays the displayed search. If any one of the results is focused, it is checked whether the user commands a detailed search for the corresponding meter data using a menu key or the like (step 424).

When the user requests a detailed search, the controller 100 shows specific information about the focused result, for example, a name, a folder path name in the case of a menu, and a file name and meta information in the case of a content file. Guide the user to find exactly the desired information (step 426).

In addition, the controller 100 checks whether the one-click execution is requested for the focused meter data through the user interface 112 (step 428).

When the one-click execution is requested, the control unit 100 executes an application program corresponding to the requested search result (step 430) and meta-executes execution information for updating the use frequency / rate of the corresponding metadata. Provided to the data management engine 104 (step 432).

Unlike the above, when the user selects a menu through the user interface unit 112, the controller 100 performs an operation for setting the menu (steps 438 and 440).

In addition, if the user selects a menu without inputting a search word through the user interface unit 112 in step 408, the controller 100 provides a bookmark through menu setting and previous search results (steps 434 and 436). .

Now, an online search method according to a preferred embodiment of the present invention will be described with reference to FIG.

When the user requests an online search, the controller 100 displays a search word input window and waits until the user inputs a search word (step 600). When the user inputs a search word through the search word input window (step 602), the controller 100 requests a search by accessing a search service server through the switch server or proxy server through the mobile communication function unit 138. do. When the control unit 100 requests the search service server to search through the switch server or proxy server, the search service server performs a search according to the search request, and sends the search result to the switch server or proxy server. to provide. The conversion server or proxy server converts the search result into a metadata format according to a preferred embodiment of the present invention and provides the converted result to the controller 100 through the mobile communication function unit 138. When the online search result of the metadata format is provided from the conversion server or the proxy server, the control unit 100 stores the search result data in the search result data DB 124 and the display unit through the output unit 126. (134).

For the displayed search results, detailed search or focusing, one-click execution, etc. are provided according to a preferred embodiment of the present invention, which is the same as the description of FIG.

However, since the search result is the wireless Internet link information, when a one-click execution command is received for the search result, the search result may be a connection to a web site or a download performed by the wireless Internet browser. .

Since the above-mentioned online search connects to a search service server through a switching server or a proxy server and performs an online search, the predetermined profit can be expected by limiting in advance a search service server to which the switching server or proxy server is connected.

In addition, the conversion server or proxy server is an example of converting the online search results into the metadata format according to the present invention to provide to the portable terminal, the conversion server or proxy server is the XML data provided from the search service server as it is It can also be provided as a portable terminal. In this case, converting the XML data into the metadata format is implemented in the portable terminal.

In addition, since a mobile terminal often uses a content search site of a mobile communication service provider rather than a general online search service, a download link to the content may be a result of the search. The results of the downloadable search for such a portable terminal can be shown like an offline search result.

In the case of a conversion server, a cache or a proxy function can be used to store frequently used content in advance so that it can be quickly transmitted to many users without delay in retrieval time.
