Description

INFORMATION ACQUISITION METHOD IN INTERNET AND COMPUTER READABLE MEDIUM FOR STORING PROGRAM FOR

CARRYING OUT THE METHOD

Technical Field

The present invention relates to a method for obtaining information through Internet and, more particularly, to a method of searching lots of information in a batch processing and viewing contents of the searched information.

Background Art

Owing to developments of communication technologies and generalization of computers, Internet is widely being used for obtaining information at homes or offices. The Internet is a worldwide computer network through which computer users can surf desired information or communicate with one another all any time. When acquiring information from the Internet, particularly in the World-Wide Web (WWW), a user commonly uses a program called a web browser. That is, the user who wishes to search information typically transmits an HTTP request to a specific web site by inputting the address of the web site and receives the information through an HTTP response from the web site. Those who frequently uses the Internet generally searches, during a session, various kinds of information in several fields rather than a single or a few web documents. Information which is frequently accessed by the Internet users include political and economic news, economic information such as stock quotes and economic indices, and cultural information related to performances, hobbies and leisure, etc. Detailed information frequently accessed by a specific user typically depends on the job, character, and age of the user. When the user is to obtain or view various information as above, the user typically sequentially selects a next web document by clicking a hyperlinked character string or image in the Hyper Text Markup Language (HTML) documents provided by the web site while browsing the web site. If a web site does not provide all the information which the user is concerned with, the user generally visits plural web sites as necessary. Meanwhile, due to the increase of the Internet users, the web servers of popular web sites have considerable traffic burdens. Accordingly, the users of such web sites frequently experience connection problems or too lower data rates. On the other hand, developments of Internet backbones and subscriber networks are slow compared with the increases of the Internet users and Internet traffic, which also influence on the speeds of the information searches and transmission rates. If the data transmission rates are so low, the users have to waste much time in obtaining desired information. In order to facilitate the information search in many and unspecified web sites, search engines are widely being used. The search engine, which maintains index data collected by a search robot in a huge database of data, provides the index data to the user to help the user find web sites relating to a requested subject. For this purpose, the search robot surfs the web to collect new or updated information from the Internet. However, the information collected by the search engine is not customized sufficiently to the needs of each user, but includes not so few web documents unnecessary to the user. Furthermore, the information provided by the search engine is not updated with the latest data because the search engine does not search all the web sites so frequently, for example, several times a day. Push technology is developed and utilized to reduce the burden of the users of visiting several web sites for collecting information and provide updated information relatively customized to the request of each user. The push technology means an information providing scheme in which a push server sends information to users before they actually request it once the user sets up a profile specifying the type of desired information. According to the push technology, the user can save considerable time for the information acquisition because the user needs not surfing a number of web sites individually to search the desired information and can view such information after downloading and storing in a hard disk. However, the push technology has a drawback in that the types of information which can be specified by each user are limited to several large categories preset by the push server Therefore, in the case that the user wants to acquire information directed to a specific subject rather than a general one, the push server cannot appropriately provide the push service Accordingly, the user often has to endure the receipt of unnecessary information when the user tries to receive the push service for a topic directed to a specific subject In such cases, the time required for the information acquisition may be much longer than the case that the push service is not utilized

Furthermore, the information source used by the push server is generally restricted to predetermined web sites For example, the push server providing the push service for a 'news' field may obtain and provide news articles from just a single or a few of newspaper sites Moreover, such a push server generally does not provide foreign news Therefore, the push technology is not utilized sufficiently in the information acquisition through the Internet, but used in a limited extent in receiving a News-on-Demand service

Disclosure of the Invention

In order to solve the above problems, the object of the present invention is to provide a information acquisition method enabling each Internet user to acquire information specifically required in his or her own standpoint regarding various topics The information acquisition method for achieving the above object is implemented by a program executed in a data terminal. The data terminal comprises a display and a recording medium for storing data, and is capable of being connected to multiple Internet servers through a communication network for searching and receiving web documents from the Internet servers to show the web documents on the display The program can be adapted to be executed in all types of terminal capable of accessing Internet The data terminal may be selected from a group comprising, but not limited to, a computer, a portable phone, or a personal digital assistance (PDA)

The user can selectively activate each of plural topics or channels in a main console having a shape of remote controller Also, when activating each topic, the user can set up a keyword for searching the web documents and an address of at least one Internet server of the plurality of servers For an activated topic, the program automatically searches and downloads web documents immediately or at a reserved time to save the downloaded documents in the recording medium After the completion of saving, the user can view the contents of the saved documents no matter whether the data terminal is connected to the communication network.

In the computer system of FIG 1, the hard disk 22 stores an operating system 50 and a web browser 52 as well as a search reservation program 54 according to the present invention The operating system 50 is loaded to the main memory 18 when the computer system is booted, and performs system management and carries out operations instructed by the user as long as the system is turned on Meanwhile, the web browser 52 and the reservation search program 54 may be selectively operated by the user That is, the programs are loaded into the main memory 18 to be executed according to instruction of the user In the case that the programs are inactivated for a long time after the initiation of the execution or the capacity of the main memory device 18 is insufficient, some of the programs may be stored in the virtual memory allocated on the hard disk 22 until the program is recalled by the operating system 50

Examples of the web browser 52 includes, but are not limited to, the Netscape Navigator (trademark) provided by Netscape Communications Corporation and the Internet Explorer (trademark) provided by Microsoft Corporation The web browser 52 enables the user to search and browse web documents when the system is connected to the Internet Also, the user can view web documents stored in the hard disk 22 of the computer regardless of the connection of the computer to the Internet The search reservation program 54 searches and acquires information from the Internet according to the user's setting of kinds of information and reservation time

FIG 2 illustrates the operation of the search reservation program 54 according to a preferred embodiment of the present invention

First, a main console is displayed on the display device 40 when the program is executed (step 70) One example of the main console is shown in FIG 3 The main console has a shape of a remote controller on which multiple buttons are arranged The buttons on the remote controller include a "VIEW" button 60, a "RESERVATION" button 61, an "EXECUTION" button 62, a "BACK" button 63, a "HOME" button 64, a "FORWARD" button 65, and a plurality of channel buttons 66a through 66i The channel buttons 66a through 66i are provided for respective information search topic, of which name and search environment may be set up and changed by the user Also, all or some of the channel buttons 66a through 66i can be selectively activated by the user When there are too many channel buttons to be displayed in a single screen, the channel buttons are displayed in two or more pages In such a case, the user may change the page by use of the "BACK" button 63 or the "FORWARD" button 65

The "RESERVATION" button 61 is used to reserve an information search through the Internet for activated channels at a certain reservation time The "EXECUTION" button 62 is used to carry out the information search immediately through the Internet for the activated channels The "VIEW" button 60 is used to view the information having been searched and stored in the hard disk 22 according to the execution of the "RESERVATION" or the "EXECUTION" function The "HOME" button 64 is used to make a connection to a homepage of the provider of the program of the present invention and download new channel information or a upgraded program patch The user can perform a desired function by clicking corresponding button in the main console For the purpose, the search reservation program 54 continuously checks whether there is any input of clicking button (step 72) If there is no input for a certain time while the program is executed, the operation mode of the program enters into an inactivation mode (step 74) In the "inactivation mode", the screens provided by the program disappears from the display device 40 and the program stands by while waiting for the user's input as a button in the task indication bar in the lower portion of the display device 40

Meanwhile, if it is determined that a button is clicked by the user in the step 72, the search reservation program 54 determines which button is clicked (steps 76 through 82) If one of the channel buttons is clicked (step 76), it is determined whether the channel button was single-clicked or double-clicked (step 84) If the channel button is determined to have been single-clicked, the channel is activated with the channel options of default values or those having been set up previously by the user The program of the present invention indicates an activated state of a channel by highlighting or solidifying the button of the corresponding channel Meanwhile, if the channel button is determined to have been double-clicked in the step 84, the program enables the user to change the channel setting by showing a channel setting console (step 88) In FIG 2, the steps 72 and the steps 76 through 82 may be implemented by a single step, alternatively FIG 4 illustrates an example of a channel setting console for setting and changing channel information according to the program of the present invention The channel setting console includes a title dialog box, and a plurality of site name dialog boxes and search keyword dialog boxes The title dialog box enables the user to change the tile of a channel in the main console of FIG 3 Each of the site name dialog boxes enables the user to input the name of a site from which the user wants to search information in connection with the channel The user may click an arrow button to open another dialog box for URL entry and input the URL of the site The search keyword dialog boxes are used to specify a keyword used for the information search In the preferred embodiment, the site name in each of the site name dialog boxes are linked to an execution module of the program, so that the user can verify the corresponding URL by double-clicking the site name and making a connection to the web site during the course of setting up or changing the channel information

When searching and saving web documents using the program of the present invention, the user can download and save either full texts or just titles of the documents In FIG 4, a "Search/Saving Style" field is used to determine the style that the web document is downloaded and stored in the hard disk "Stand-by Time" means the time peπod the program waits for the response from each of the web sites When the stand-by time for a web site expires, the program terminates the connection to the web site and tries to establish a connection to another web site or stop the search operation

In the preferred embodiment, the search keyword may be specified separately to each of the plurality of web sites Alternatively, however, a single keyword may be commonly specified to all the web sites belonging to a channel When carrying out the search, the program accesses a search page of each web site and provides the keyword to the search page, so that the server of the web site performs the search for the keyword and transmits the search result In case that the web site does not provide the search page, the program requests the search to an external search engine with the specification of the keyword, domain name, and created date Alternatively, the program of the present invention may include its own search robot If the channel setting is completely specified or changed in step 88, the channel is activated

Referring back to FIG 2, when it is determined that a button is clicked m the step 72 and the clicked button is the "EXECUTION" (step 78), information search process is carried out immediately according to the channel settings Searched information is sequentially stored in the hard disk FIG 5 illustrates the searching and saving process in detail First, the program searches and downloads information of the activated channels according to the setting of the channels (step 100) The downloaded web documents are stored in the hard disk (step 102) Upon completion of the search process, the program shows a completion message on the display so that the user may know the completion FIG. 6 illustrates an example of a directory structure of web documents stored in the hard disk. As shown in the drawings, the name of each subdirectory is assigned according to the date and time at which the saving task is carried out. For example, when a downloading and saving process is initiated at 05:00 of July 29, a subdirectory "0500" is created under a directory "0729" so that download web documents are stored in this directory. In case that the saving processes by the program are carried out twice in a day, for example at 05:00 and at 12:30, two subdirectories "0500" and "1230" are created and download web documents are stored in the directory corresponding to the respective session. Meanwhile, the directory structure of FIG. 6 applies in the case that each web document is saved into at least one file. However, in the case that the "Search/Saving Style" field has been set so that only the titles of web titles are stored, all the titles downloaded in a session are saved into a single file.

Referring back to FIG. 2, when it is determined that the "RESERVATION" button is clicked in the step 80, reserved search process is carried out according to the channel settings (step 26). In a preferred embodiment, the user may reserve a time and keyword after clicking the "RESERVATION" button 61 (step 92). Accordingly, the search process is carried out at the reserved time using the reserved keyword. All the channel settings mentioned in connection with the steps 86 and 88 other than the reserved time and keyword are used In the reserved search process. Alternatively, the reservation time and keyword may not be input after the "RESERVATION" button is clicked, so that all the channel settings input through the channel setting console may be used in the reservation search precess. Particularly, the reservation search precess may be performed periodically as long as the computer is turned on. In such a case, it is preferable that dialog boxes for inputting "RESERVATION TIME", "PERIODIC RESERVATION CHECK" and "RESERVATION PERIOD" is added in the channel setting console of FIG. 4. The web documents searched and downloaded during the reservation search precess are stored in the hard disk according to the directory structure of FIG. 5, also.

When it is determined that the "VIEW" button is clicked in the step 82, the program shows to the user the web documents stored according to the execution of the "EXECUTION" or the "RESERVATION" instruction (step 96) FIGS 7A and 7B illustrate the step 96 in detail, and FIGS 8A and 8B illustrate examples of displaying console for showing the stored web documents

As shown in FIGS 8A and 8B, the displaying console obviously shows the web documents found during the search process and stored in the hard disk The displaying console shows the name of the channel and site name in addition to the title for each document As shown in FIG 8A, when the program saves only the title but not the contents because the "Search/Saving Style" check box in FIG 4 has not been checked, a check box for downloading and saving the document is added for each web document while a "VIEW Immediately" and "SAVE" buttons are included in the lower part of the displaying console As shown in FIG 8B, when the program saves full text of each document according to the setting of the "Search/Saving Style" check box in FIG 4, a "VIEW Immediately" button is included in the lower part of the displaying console

Referring to FIGS 7 A and 7B, the program determines, in response to the user's clicking of the "VIEW" button in FIG 3, whether the document list exceeds one page of screen (step 110) If the document list exceeds the length of one page in the step 110, the program enables the "FORWARD" button (step 112) If the document list does not exceed the length of one page in the step 110, the program does not show or disables the "FORWARD" button (step 114) Then, the program shows the document list of the first page on the display (step 116)

When the document list is displayed, the user may check the detailed content of each document If the user double-clicks a document or single-clicks the document and then clicks the "VIEW Immediately" (step 118), the program checks whether the full text of the document is stored in the hard disk (step 120) If the full text of the selected document is stored in the hard disk, the full text is displayed on the screen (step 122) After checking the content of the document, the user may return to the document list screen by clicking a "BACK" or "PREVIOUS PAGE" button (step 124) Meanwhile, when the full texts of the listed documents are not stored in the hard disk in the step 120, the user may download the full text of one or more documents to display or save in the hard disk (step 126) On the other hand, the user may omit the downloading and saving step and return the document list screen

Steps 128 through 140 shows the downloading and saving process of selected the document When the user want to download and view a specific document in the document list screen, the user may double-click the document (step 128) Alternatively, the user may single-click the document and then click the "VIEW Immediately" in the display console of FIG 8A Then, the program makes a HTTP request to the corresponding web site to download and show the document (steps 130 and 132) On the other hand, the user may wish to download and save a plurality of documents rather than a single document, so that the user may sequentially check the contents of the selected documents In such a case, the user may select concerned documents by checking in the check boxes for the documents and click the "SAVE" button in the lower part of the displaying console of FIG. 8 A When the "SAVE" button is clicked in step 134, the program determines whether at least one check box is checked in the display console of FIG 8A (step 136) If at least one check box is checked, the program creates a new directory and downloads the checked documents to save in the new directory (step 138) If it is determined that no check box is checked in the step 136, the program downloads and saves all the documents in the list (step 140) At this time, a message confirming that whether all the documents are downloaded may be provided in the display On the other hand, if a button other than the "SAVE " button, e g , "FORWARD ",

"BACK", or "PREVIOUS PAGE" button, is clicked in the step 134, a function corresponding to the button is carried out (step 135) Similarly, if another button is clicked in the step 118, 124, or 126 in FIG 7 A, the function corresponding to the clicked button is carried out On the other hand, the amount of data stored in the hard disk may be too enormous if all the web documents corresponding to the preset keyword are downloaded and stored as described above Thus, in an alternative of the preferred embodiment, the program may download only the titles of the web documents corresponding to the preset keyword to save or display the list of the titles. The user may choose one or more titles in the list to view detailed contents of the document. Such an information acquisition method is suitable for acquiring news articles corresponding to a specific keyword from a plurality of online newspaper sites For information other than news, however, it is preferable to download whole contents of the web documents corresponding to the keyword or URL preset by the user In case that plural documents are downloaded from at least one web site, it is preferable to change URL linking information in the documents when the documents are stored in the hard disk Thus, the program of the present invention preferably includes a parser for analyzing and manipulating tags in the HTML or WAP documents For facilitating the search of news articles, the program preferably includes URLs of news providing sites famous domestically or internationally Here, the URL may be a detailed URL of the web page for the "News Search" In such a case, the program transmits a HTTP request for the web page while including the keyword set by the user in the header of the HTTP request FIG 9 illustrates the computer program according to the preferred embodiment of the present invention A user interface 300 receives user inputs from input units such as the keyboard or the mouse and shows the program execution result in the display device A main control module 302 controls the overall operation of the program A search module 304 searches and downloads information of the channel set by the user under the control of the main control module 302 In the case that the downloaded information is a news article, the downloaded result is stored in the hard disk 22 by a saving/reading module 306 In the case that the downloaded information are web documents other than the news article, the downloaded results are stored in the hard disk 22 after the URL linking information is changed by the parsing module 308 Tables 310 stores the user preset data such as channel information, URLs of each channel, the search keyword for the news channel, and a reservation time or period for the automatic searching Such tables may be stored in the hard disk 22

Although the present invention has been described in detail above, it should be understood that the foregoing description is illustrative and not restrictive Those of ordinary skill in the art will appreciate that many obvious modifications can be made to the invention without departing from its spirit or essential characteristics For example, in the preferred embodiment, the program according to the present invention includes a TCP/IP protocol interpreter, and searches information according to the TCP/IP protocol and saves the search result in the hard disk Thus, the user may view the search result using a web browser later Alternatively, however, the program may operate the web browser in response to the channel setting and the operation instruction of the user, so that the web browser searches information and saves the search result in the hard disk In another alternative embodiment, the program of the present invention may be employed in the web browser as a component In yet another alternative embodiment, the program of the present invention may a built-in web browser to perform the function of displaying the detailed contents of the searched documents In such a case, the user may easily view the obtained web documents without a separate web browser.

Even though it was described in the foregoing description that the program was installed and executed in a user's terminal such as a personal computer of the user, the program may be installed in a web server or a personal computer of the operator of the web server In such a case, the downloaded information may be stored in the LAN host, so that members of the organization can share the information Also, the program of the present invention may be implemented in an Internet-TV enabling the user to carry out web surfing In this case, the main console screen of FIG 3 for setting and changing the operating environment of the program and controlling the operation of the program may by replaced with the real remote controller of the TV which has a physical shape

The information acquisition method of the present invention differs from "push" technology in that the subject who controls the searching and downloading process is not a specific server but the user Meanwhile, according to the present invention, the user can define and organize needed information more actively and comprehensively than the conventional "pull" scheme in which the user searches and downloads individual information as necessary In this regard, the information acquisition method of the present invention can be referred to as "active pull" scheme Industrial Applicability

As described above, the present invention enables the user to set kinds of information or Internet sites which the user searches information periodically or frequently, so that the user conveniently views the information downloaded before the view Thus, the user can make a reservation when going out or leaving the office and view the downloaded information later Also, the program of the present invention can be executed while the user performs other operation according to the multitasking function provided by the operating system of the computer. Thus, when the user tries to obtain plural web documents by transmitting the plurality of HTTP requests, the user need not wait for the completion of a HTTP response before another HTTP request for obtaining next web document Accordingly, the time efficiency in surfing the Internet may be enhanced Also, since the user need not search desired information by consecutively clicking into lower depths consecutively, the user is less exposed to advertisement banners and can save time while the information is downloaded.

In addition, since the main console provided by the program has a shape of a remote controller, the user can be acquainted with and thus conveniently use the program Thus, even a novice can use the Internet easily using default channels without any training or education Further, since the user can arbitrarily add or change desired topics ,or channels, the user can customize various channels to his or her taste or needs In other words, the program according to the present invention can bring about a result that the user constructs a personalized portal site.

The user can update the program or add channel information by making a connection to a web site of the program provider to download new topics or program patches Particularly, the program provider can assign rankings to web sites of each category through a survey among the users of the program, so that each user can obtain information from most adequate sites Also, the program provider can include, in the default channels provided initially and additionally, web sites favored by the users so as to guide each web site to enhance quality of web contents. Thus, the present invention can contribute to the upbringing of healthy web sites.
