## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of Korean Patent Application No. 10-2007-0055788, filed on Jun. 8, 2007, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety for all purpose.
BACKGROUND OF THE INVENTION
The present invention relates to a method and system for providing additional information service onto e-mail in response to receiving a user-initiated selection, more particularly to a method and system for providing additional information service onto e-mail where the information pattern of a predetermined string of the content of a received e-mail is automatically recognized, and the additional information related with the string can be provided to the user along with the content (basic information) of the e-mail by a simple operation, so the user can conveniently use the e-mail service.
Email system facilitates the exchange of electronic mails over a network, such as a LAN (local area network), WAN (wide area network), or public network (e.g., Internet). FIG. 1 illustrates an exemplary screen display of a web page for providing a conventional e-mail service. The conventional e-mail service only provides content of an e-mail that is written by a sender. However, a recipient sometimes wants to obtain additional information related to some text or graphical items included in the content. For example, when the text of the e-mail includes a person's name or company name, if the user wants to check the related information (e.g., the person's address, phone number, e-mail address, etc.), he would have to find the information by executing a separate address list program, operating a PDA, or using other ways.
Especially, if a person receives a meeting or business-related e-mail wherein names or phone numbers are included, it might take significant time for him to search related information about each name or each phone number, that is additional contact information for the each person or the each phone number.
Generally, a portal website having an e-mail service provides an online service for searching an address list. However, where the user searches the related information using an external service or separately implementing program, it is still inconvenient because the user should temporarily leave the web page showing the email and move to the service page or a search screen, and search the name or the phone number one by one, and while frequently changing the screen, requesting a separate service, and executing a separate program, the efficiency of computer resources or network resources manage is lowered, which is problematic.
It is therefore desirable to provide a method and system for providing additional information related to content of an e-mail without leaving the web page showing the email.
Specific advantages and features of the invention will be apparent from the attached drawings and description of an illustrative embodiment of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The exemplary embodiments are described below in order to explain the present invention by referring to the figures.
FIG. 2 illustrates the configuration of a system for providing an additional information service onto e-mail according to an exemplary embodiment of the present invention.
Referring to FIG. 2, the system for providing an additional information service onto e-mail of the present invention can have access to a browser 10 mounted on a user terminal through a network, wherein the system may include a web server 50 and an e-mail server 60.
The user terminal where the browser 10 is executed is a device that can connect to Internet network, and search, output and store information according to manipulation of a predetermined input means such as a keyboard, a mouse and a touch pad. Some examples of the user terminal are a general computer such as a desktop computer and a notebook computer, other devices where information networking is possible in a ubiquitous environment, and a mobile device such as a PDA and a mobile phone.
The e-mail server 60 implements a web page for providing an e-mail service to a registered user, provides an e-mail account of a certain capacity, and provides the user with e-mails sent or received through the allocated account.
The web server 50 transmits data that constitute the web site so that the e-mail service can be provided through the browser 10, and transmits the related data according to the user's request transmitted from the browser 10.
Further, the system for providing the additional information system onto e-mail according to the present invention searches additional information related with predetermined information included in the request message in accordance with the request message from the e-mail server 60 or the web server 50, and can further include a content server 70 that transmits the search result to the e-mail server 60 or the web server 50.
The content server 70 can be linked with a server for additional services such as an address list service, a location-based service, a time/date-based service and a knowledge-providing service, or can be implemented in the form of an additional service server, so it is possible for directly or indirectly accessible various databases to be referred and for the information to be searched and provided.
The system for providing the e-mail service according to the present invention may be implemented in the form of a portal server 20 that includes the e-mail server 60, the web server 50 and the content server 70. The portal server 20 can provide many and unspecified persons or registered users with several services such as a search service, an e-mail service, a chatting service, a club service, a text message service, a shopping mall service, a game service and a blog service integrally by including all of the above-mentioned servers and by being connected to each sever through network, and transmitting and receiving data.
Based on the above-mentioned network infrastructure and the various modified environments, the web server 50 of the embodiment analyzes the information pattern by determining whether there is any string corresponding to a predetermined information pattern after analyzing basic information of an e-mail (content of an e-mail) for the e-mail provided to a user, by checking each string whether it corresponds to a predetermined information pattern, or according to other modified algorithms.
The information pattern is used for providing related information that can be useful when the user refers to received e-mails, and there can be various items such as a name/title, a unit, market information, an e-mail address, a phone number, location information such as an address and time/date information. Further, the types of the related additional information that can be provided through a search according to each classified pattern can vary depending on the setting, and some examples of the types are an address list, weather information, the exchange rate, a news article, fortune information, person search information, stock price information, book information and URL.
Hence, various types of additional information can be searched for a string that belongs to one of the information patterns. Here, it is possible to provide various types of additional information in parallel so that the user can selectively refer to the information. Further, after analyzing the user's disposition including the frequency of types of content provided through the web server, it is possible to provide high-ranking items by selecting additional information corresponding to the content types of high frequency among the searched types of additional information.
The analysis of the information pattern and providing of the corresponding additional information can be set to be provided only when requested by the e-mail sender or receiver, or the types of the information pattern included in the analysis can be set to be specified by the sender or receiver.
The additional information according to the obtained information pattern is provided to the user's terminal when the user refers to the basic information of an e-mail using the terminal. Here, in order not to hinder the reading of the basic information, it may be desirable for the additional information to be shown when the information region including the string is indicated instead of showing the additional information continuously.
For example, if a certain person's name is written in an e-mail, when a region around the text is indicated by the mouse, it is possible to show the search result of the address list, for example, the phone number, the e-mail address, the occupation and the address. Further, it is possible to show the information on the screen using secured space by changing the basic information format of the e-mail service or using a separate window. Detailed description of the operation will be described in the following using an exemplary embodiment, so the description is omitted here.
FIG. 3 is a flowchart illustrating a method of providing an additional information service onto e-mail according to an exemplary embodiment of the present invention. Referring to FIG. 3, when one of the displayed received e-mails is selected by an input means such as a mouse, a keyboard, a touch pan or a touch pad in step S10, the browser 10 can generate a text-request message of the selected e-mail, and send the message to the web server 50 in step S20.
In step S30, the web server 50 reads the received text-request message, and sends a request for the original content of the e-mail to the e-mail server 60, and the e-mail server 60 searches the e-mail corresponding to the request message, and transmits the original text of the searched e-mail to the web server 50.
In step S40, the web server 50 analyzes text data of the content of the e-mail received from the e-mail server 60, determines whether some of the strings that constitute the text data can be classified as a predetermined information pattern, and classifies the corresponding strings according to each pattern.
Specific examples of classification algorithms by information patterns can vary. For example, if two to four consonants and vowels of Korean letters or two to four Chinese characters are consecutively arranged, or the first alphabet out of multiple alphabets arranged right and left based on the space is a capital letter, the string can be classified as having an information pattern corresponding to “Name.”
As another example, in the case where a multiple of numbers are connected by two or three hyphens, or a string is a combination of a multiple or numbers and letters, if the string includes at least one of “year”, “month” and “day”, and at least one number is arranged before the word, the string can be classified as having an information pattern corresponding to “Date.”
In the string where a multiple of numbers are connected by two or three hyphens, if the string is started with the number of “010”, “011”, “016” or “019”, the string can be classified as having an information pattern corresponding to “Phone number”.
Also, if there is a symbol “@” between multiple letters, and at least one “.” is included in letters following “@”, the string can be classified as having the information pattern of “e-mail address.”
Likewise, if there is at least one of the strings classified according to the information pattern, in step S50, the web server 50 transmits each string and the corresponding information pattern to the content server 70 to request additional information related with each string, and the content server 70 searches additional information related with the requested string with reference to the information pattern item, and the search result data to the web server 50.
For example, while analyzing the text of an e-mail, the string “Hong, Gil-Dong” is classified as the information pattern of “Name”, and the data is transmitted to the content server 70. The content server 70 recognizes that there is a need for additional information corresponding to the information pattern of “Name” through the received data, and searches data corresponding to “Hong, Gil-Dong” from the content server 70 or the address list database of the linked additional service server. If there is any related information such as the person's e-mail address, mobile phone number and address, the content server 70 transmits the information to the web server 50.
Next, in step S60, the web server 50 includes the additional information data received from the content server 70 in the basic information data of the e-mail. Here, it may be desirable for the additional information data included in the basic information data of the e-mail to be included in the hid format within the text of the e-mail so that the additional information does not hinder the reading of the basic information of the e-mail.
In step S70, the web server 50 transmits the text data of the e-mail including the additional information data to the web browser, and the web browser displays the content of the e-mail on the screen in such a manner that the additional information data is not shown.
Further, in step S80, while the user reads the content of the e-mail displayed on the browser, if a pointer (or another user interface means such as a cursor) outputted on the terminal screen is positioned in the information region related with the string of the predetermined pattern, in step S90, the browser 10 recognizes that the pointer is positioned in the region, and displays the additional information that has been hid.
In step S40, if the name “Hong, Gil-Dong” is searched and a multiple of persons of the name are found in the address list, all found data may be displayed, or the first found data may be displayed and it may be implied that there is more data by indicting a mark for additional data so that the user may choose to read the additional data. Here, the frequency of access to data may be referred.
Here, the web server 50 can allow the additional information to be outputted in a pop-up format in an appropriate position to be outputted right after the string of the text of the e-mail if the amount of the additional information is not much by automatically changing the basic information format of the e-mail. Also, various other separate window formats such as a pop-up window, a layer and a balloon can be used using related technologies such as HTML tag, JavaScript and CSS (Cascaded Style Sheet) code.
FIG. 4 is a block diagram illustrating a configuration of a web server in a system for providing an additional information system onto e-mail according to an exemplary embodiment of the present invention. The web server used in the embodiment can include a server-control module 51, a pattern-recognition module 52 and an information-search module 53, and can further include a user database 54 and a communication module 55.
The server-control module 51 controls general operation of the web server 50, and if the user terminal is connected to the web server 50 through the browser 10, the server-control module 51 transmits a main web page that includes a service list available in the web server 50 to the user terminal. Further, in the case where the user intends to use a service that requires user authentication, the user authentication data is received from the browser, and it is determined whether the received authentication data coincides with the registered user data.
Especially, in using an e-mail service, the server-control module 51 transmits the list of the received e-mails to the browser, and if one of the letters is selected, and a request for the content of the selected letter is received, the server-control module 51 requests the content of the e-mail to the e-mail server 60, and receives the content. Further, if the additional information is received for a predetermined string included in the e-mail, the server-control module 51 transmits the data to the browser 10 along with the content of the e-mail.
Here, it may be desirable for the additional information data included in the basic information data of the e-mail to be included in the hid format within the text of the e-mail so that the additional information does not hinder the reading of the basic information of the e-mail. That is, when the content data of e-mail is transmitted to the browser 10 and the content data is displayed on the browser, the additional information is not shown. Meanwhile, when the pointer on the browser is positioned at the predetermined string, the additional information is displayed on the browser. As mentioned above, the displayed additional information may be displayed in various types through the use of related technologies applicable to the browser.
The pattern-recognition module 52 analyzes at least one of the strings that constitute the content of the e-mail transmitted through the server-control module 51, and determines whether the string can be classified as a predetermined information pattern. In this case, various analyzing methods such as analyzing by recognizing morphemes that constitute each string using a morpheme analyzer or analyzing ASCII code corresponding to each letter may be used, and the methods may be applied in various manners depending on the intention of the e-mail service provider of the present invention.
The pattern-recognition module 52 classifies the analyzed strings according to the information pattern. As described above, the information patterns can be classified as Name/Title, Phone number, E-mail address, Address, Time/Date, etc., and the types of the related content can be selected according to the classified information pattern.
For example, in the case of a string recognized as the information pattern “Date”, the related additional information may include the weather, the calendar, exchange rate information, traffic information, stock price information, etc. Here, if all the searched additional information is included in the content of the selected e-mail, the amount of data transferred increases, by which it may take significant time in transferring data and in processing the data in order to output the data. Hence, it may be desirable for the user to choose desired types of information so that only the selected information is included in the content of the selected e-mail.
Hence, if a multiple of sets of related additional information for the string corresponding to a predetermined information pattern are searched, the pattern-recognition module 52 analyzes the frequency of the content used, selects the content type of high frequency, transmits the string of the information pattern and the data of the selected content type to the information-search module 53 so that the additional information may be searched according to the selected content type in the information-search module 53.
The information-search module 53 searches the string of a predetermined pattern transmitted from the pattern-recognition module 52, and if the content type data is received along with the string of a predetermined pattern, the information related with the string is searched for the content type.
Here, the content database may be included in the web server 50, or if the database is built in a separate form of a content server 70, which is a network server, the information-search module 53 generates a message to request a data search, transmits the message to the content server 70, and the related information received from the content server 70 is transmitted to the server-control module 51. Here, the content server 70 can include a content database 71 where a great amount of content that can be provided through the web server 50 is stored, and a server-control module 72 that reads the request message received from the information-search module 53, searches the string included in the message according to the content type, and transmits the search result to the web server 50. Various types of content can be integrally stored in the content database (DB) 71, or the content DB 71 may establish a separate sub database by types. Here, if the provider is different according to the content type, the related information can be provided as a multiple of content servers are linked with the web server.
Further, the web server 50 includes personal information of registered users, a user DB 54 that stores user profile such as service-related data for each user, and a communication module 55 that converts data so that the data can be transmitted and received through network.
FIG. 5 illustrates a screen of providing an e-mail service shown on a terminal according to an exemplary embodiment of the present invention. If one of the received e-mails is selected in a browser 10 connected to Internet, the content of the selected e-mail is shown as illustrated in FIG. 5. Here, when a pointer (or another means to indicate the position in the screen such as a cursor) such as a mouse is positioned in the region where a phone number string is positioned, a pop-up window arranged adjacent to the pointer is outputted. The pop-up window has been transmitted along with the text of the e-mail after the phone number string was automatically recognized in the web server, and the related information was received from the content server 70. It is desirable for the pop-up window to be shown only when the pointer is positioned in the phone number string in order not to hinder the reading of the e-mail. The illustrated drawing shows a case where an e-mail address is shown through a separate window if the region is indicated when a mobile phone number of a certain person is shown in the text of an e-mail.
FIG. 6 illustrates a screen of providing an e-mail service shown on a terminal according to an exemplary embodiment of the present invention, FIG. 6A illustrates a screen right after the text of the selected e-mail is outputted, and FIG. 6B illustrates a screen where the related information is inserted to a phone number string if a pointer is positioned in the string.
Referring to FIG. 6A, if one of the received e-mails is selected, the content of the selected e-mail is outputted. Here, the text of the outputted e-mail includes the additional information transmitted from the web server 50, but the additional information is not yet shown.
While the user reads the text, if the user positions the pointer in the string recognized as a phone number pattern, as illustrated in FIG. 6B, the format of the basic information of the e-mail is automatically changed, and the additional information is inserted in the space secured by the change of the format, so there is a change in the content of the outputted e-mail shown in the screen.
Here, the string recognized as “Name” information pattern or “Phone number” information includes different types of related information, information additional information such as the name may be outputted in such a manner that the information is inserted in the text, and the additional information with large amount such as a phone number or an e-mail address may be outputted on the screen as a separate format such as a pop-up window.
FIG. 7 illustrates a screen of providing an e-mail service shown on a terminal according to an exemplary embodiment of the present invention. Here, a screen of providing an e-mail service in the case of a string recognized as a date pattern is illustrated here. Referring to FIG. 7, before the text of the selected e-mail is outputted, the web server 50 receives the text data of the e-mail transmitted from the e-mail server 60, and determines whether there is a string of a predetermined information pattern. As a result, if there is a string having “Date” information pattern, the web server 50 sends a request for weather information of the date corresponding to the string to the content sever 70 in order to obtain weather information data. The content server 70 transmits the weather information data received from the weather information database to the web server 50, and the web server 50 transmits the received weather information data and the text of the received e-mail to the terminal. The browser 10 outputs the text data of the received e-mail on the screen, and the enclosed weather information data is hid while being connected to the “Date” pattern string of the text of the e-mail. While user reads the text, if the pointer is positioned at the date pattern string, the weather information data may be outputted in the browser as a separate format such as a pop-up window.
