The touch pad 135 operates in association with the display unit 151. The touch pad 135 may be located parallel to the rear of the display unit 151. The touch pad 135 may have the same or smaller size as the display unit 151.

The electronic device 100 including the configuration described above may output a message transmitted or received through the wireless communication unit 110 to the display unit 151. As such, when a message is output to the display unit 151, the keyword extractor 125 may extract at least one keyword related to a schedule from the output message. Then, the controller 180 may assign a score to a keyword extracted through the keyword extractor 125 based on a predetermined criterion. If a predetermined score is given to each extracted keyword and the sum thereof exceeds a predetermined threshold value, the controller 180 may automatically generate a schedule based on the extracted keyword. The controller 180 registers the generated schedule in a scheduling calendar of the electronic device 100.

As described above, according to the electronic device according to an embodiment of the present invention, if a keyword related to a schedule is included in a message transmitted and received through the electronic device 100, the electronic device 100 extracts the keyword and sums the scores assigned to the extracted keywords. If it is determined based on the schedule to provide a user convenience by automatically creating a schedule to be registered in the calendar.

Hereinafter, a method of automatically generating a schedule from a message output from the electronic device will be described with reference to FIGS. 1, 3, and 4.

In this regard, FIG. 3 is a flowchart illustrating a method for automatically generating a schedule of an electronic device according to an embodiment of the present disclosure. 4 is a conceptual diagram illustrating the automatic schedule generation method of FIG. 3.

Referring to FIG. 3, the electronic device 100 outputs a message transmitted or received through the wireless communication unit 110 to the display unit 151 (S310).

Here, the message may mean an SMS text message, an e-mail, a chat log file using SNS, and the like. In addition, although the message transmitted or received through the wireless communication unit 110 has been described as an example, for example, a message recorded by the user by running the notepad application on the electronic device 100 may be included.

For example, referring to FIG. 4A, the electronic device 100 may output an instant message 401 written by a user and an instant message 402 received from the outside to the display unit 151.

The electronic device 100 may extract at least one keyword related to a schedule from the message output to the display unit 151 (S320). To this end, the electronic device 100 may include a keyword extraction unit 125 for extracting at least one keyword associated with a schedule.

Here, the schedule means a plan including time and / or place information scheduled by the user.

In this case, the keyword associated with a schedule may mean text including time information or place information. For example, the text includes time information such as' 5 o'clock and 'tomorrow' and the text including place information such as' My House 'and' Gangnam Station '.

For example, as shown in FIG. 4A, when an instant message 402, “There is a meeting in the afternoon and meet at 11 am tomorrow” is received, the controller 180 includes time information. The texts 'PM' 402a, 'tomorrow' 402c, 'AM' 402d, and '11 o '' 402e may be extracted as keywords related to a schedule.

In this case, the controller 180 may extract keywords related to a schedule in a space unit or extract a noun unit except a survey. In addition, the controller 180 may output a text that is recognized as a keyword related to a schedule to be distinguished from other texts, for example, an underlined process, a color change, and the like.

The keyword extractor 125 may extract the text as a keyword related to a schedule when a combination of a text including at least one of time information and place information and a pre-stored character string is found in the output message.

Here, the pre-stored character string is, for example, text to recognize that text including time information or place information is related to a schedule, and serves as a primary judgment criterion for keyword extraction. For example, special phrases frequently used for announcements related to meetings (e.g. 'Meet Let's',' Meet ',' Let's, 'Agenda', 'Let's',' Come ', etc.) Characters (eg, '// see', 'meet!',) May correspond. At this time, the pre-stored string is searched but may not be an extraction target. In other words, it may be difficult to see the keyword related to the schedule by simply including the time information or the place information. Therefore, when a predetermined string to be recognized as content related to the schedule is searched together, the keyword is restricted to be extracted. .

For example, in FIG. 4A, the received instant message 402 includes the text 'PM' 402a, 'Tomorrow' 402c, 'AM' 402d, and '11 o'clock containing time information. Strings of "meet" 402f along with "402e" will be searched, so the texts' PM '402a,' tomorrow '402c,' AM '402d, '11 o' 402e) may be extracted as a keyword.

When the keyword is extracted as described above, the controller 180 assigns a score to the extracted keyword based on a predetermined criterion (S330).

Here, the predetermined criterion may mean whether to assign a score to the extracted keyword and a setting criterion for setting a value of a score to be assigned to the extracted keyword. For example, the controller 180 may assign a score when at least a plurality of keywords are extracted. In addition, the controller 180 may assign different scores according to the type of the message, the attribute of the keyword, and the like.

In addition, the score (score) refers to a cumulative score for one extracted keywords or a plurality of keywords to be recognized as a meaningful 'schedule'. For example, the controller 180 gives 5 points when the text including time information is extracted and gives 3 points when the text including place information is extracted, and extracts text including time information and place information. If you get 8 points.

As such, the controller 180 may preset scores to be assigned to each extracted keyword. In addition, the controller 180 may preset classification criteria for classifying the extracted keywords in order to assign various scores to the extracted keywords.

In addition, the controller 180 may perform the above-described steps S320 and S330 whenever a specific message is transmitted or confirm a received specific message, or may be performed on all messages output for a preset time. You may.

When a score is assigned to the extracted keyword, the controller 180 may determine whether the sum of the scores exceeds a predetermined threshold value (S340).

As a result of the determination, if the sum of the accumulated scores exceeds a predetermined threshold value, it is determined that a schedule is detected from the message, and the controller 180 automatically generates a schedule based on the extracted keyword to schedule the calendar. Calendar) (S350).

Here, the predetermined threshold means a cumulative minimum score value for recognizing extracted keywords as a schedule. That is, it means a second judgment criterion for recognizing that the extracted text is related to a schedule. For example, when the score given to the extracted keyword exceeds 10 points, the controller 180 recognizes that the 'schedule' is detected and generates a schedule including the corresponding keywords.

For example, in FIG. 4A, the text including time information included in the instant message 402 includes 'pm' 402a, 'tomorrow' 402c, 'am' 402d, and '11 o'clock. 402e, a total of four keywords related to the schedule are extracted. The controller 180 may assign a predetermined score (eg, 5 points) to each extracted keyword. For example, if the sum of the accumulated scores is 20 and the threshold score value for recognizing that the message includes the schedule is 10, the controller 180 determines that the schedule includes the schedule in the instant message 402. Can be.

In this case, as shown in FIG. 4A, the contents of texts including time information included in the instant message 402 may collide with each other. That is, the afternoon 402a belonging to the first group and the tomorrow 402c, the morning 402d, and the 11:00 o'clock 402e belonging to the second group may not be one schedule. In this case, the controller 180 can generate a schedule by selecting a group having many extracted keywords. In other words, the text belonging to the first group may be discarded and the schedule may be generated from the text belonging to the second group.

For example, referring to FIG. 4B, '11 AM tomorrow 'may be generated as a new schedule and registered in the calendar 430. The controller 180 can directly display the contents of the generated schedule in a region where a corresponding date (eg, 2013.5.11) of the calendar 430 is displayed. In addition, the controller 180 outputs only an indicator 431 indicating that a new schedule is registered in an area where a corresponding date (eg, 2013.5.11) is displayed, and when a touch on an area where the corresponding date is displayed is detected. As shown in (c) of FIG. 4, the content of the registered schedule may be output to the display unit 180. In addition, although not shown, messages sent and received with respect to a registered schedule according to a predetermined control signal may be output together in one region of the display unit 180.

On the other hand, if it is determined in step S340 that the sum of the scores is less than the predetermined threshold value, since the schedule is not detected, the controller 180 returns to step S310 and repeats the above processes or repeats the new process. You can wait for the message to be written or received.

As described above, if a message related to a schedule is included in a message transmitted and received through an electronic device, the extracted keyword is extracted, and when the extracted keywords are recognized as a schedule, a user is automatically generated to register the calendar and registered in a calendar. Can provide convenience.

Hereinafter, a method of assigning a score to the extracted keyword will be described with reference to FIGS. 3 to 5B.

5A and 5B are conceptual views illustrating a method of assigning a score to a keyword extracted from a message according to an embodiment of the present invention.

The electronic device 100 may output a message transmitted or received through the wireless communication unit 110 to the display unit 151. Here, the message includes an SMS text message, an e-mail, a chat log file using SNS, and the like.

When the message is output, the electronic device 100 extracts at least one keyword related to a schedule from the message output to the display unit 151. Herein, a keyword related to a schedule may mean text including time information or place information. For example, the text includes time information such as' 5 o'clock and 'tomorrow' and the text including place information such as' My House 'and' Gangnam Station '.

When the keyword is extracted as described above, the controller 180 assigns a score to the extracted keyword based on a predetermined criterion. Here, score refers to a cumulative score for one extracted keyword or a plurality of keywords to be recognized as a meaningful 'schedule'.

In this case, the controller 180 may preset a score to be assigned to each extracted keyword. In addition, the controller 180 may preset classification criteria for classifying the extracted keywords in order to assign various scores to the extracted keywords.

In addition, the controller 180 may set at least one item for classifying the extracted keyword and a score corresponding to the item.

For example, the extracted keywords may be classified into a plurality of items including at least one of a time item, a place item, a topic item, and a content item related to a schedule. The time item means time information of the schedule, the place item means place information of the schedule, and the subject item means subject information of the schedule. In addition, the content refers to other information related to the schedule. For example, referring to FIG. 4A, when the extracted keyword is' am 'or '11 o', it may be classified as belonging to a time item.

In addition, as illustrated in FIG. 5A, the controller 180 may include, for example, a score of five points for a time item, a score of three points for a place item, a score of two points for a topic item, and the like. In addition, a score '1 point' may be preset to a content item related to a topic.

As such, when the extracted keyword is classified according to a predetermined category, the controller 180 may assign a score to the extracted keyword based on the item to which the extracted keyword belongs.

For example, keywords 'PM 402a', 'Meeting 402b', 'Tomorrow 402c', 'AM 402d' extracted from the instant message 402 received in FIG. '11 o'clock 402e 'may be given five points, two points, five points, five points, and five points, respectively, according to the example table shown in FIG. 5A. In this case, when the contents of the extracted keywords collide with or collide with other keywords, such as 'PM 402a' and 'meeting 402b', the contents of the extracted keywords may be discarded when calculating the total score. That is, the sum of the scores calculated from the keywords extracted from the received instant message 402 may be 15 points excluding the scores corresponding to the afternoon 402a and the meeting 402b.

In assigning a score to the extracted keyword, the controller 180 may set a score corresponding to the item based on the amount of the message and the ratio of the keyword extracted from the message.

For example, the controller 180 may predetermine the minimum number of keywords for determining that a schedule is included when the content of the message is large. Also, for example, when the content of the message is small, the controller 180 may recognize it as a schedule even if only one keyword is extracted. In addition, for example, in the case of a message type (eg, an email) having a relatively large amount of messages, the controller 180 sets a score and / or a threshold value for recognizing a schedule as a high value and a relatively small message type. In the case of (eg, a message in SNS), a score and / or a threshold value for recognizing a schedule may be set to a low value.

In addition, the controller 180 may assign a large score if the item to which the extracted keyword belongs is an item related to time, and give a small score if the item to which the extracted keyword belongs is an item related to a topic or an item related to content. Can be. In the case of a schedule or an appointment, time is the most important, and therefore, it may be reasonable to assign a higher score to a keyword belonging to a time item even when assigning a score for identifying the extracted keyword as a schedule.

For example, as shown in FIG. 5A, five points, which are the largest scores, may be set for a time item, and two or one points may be set for a topic item or a content item that is more related to a schedule.

When a score is assigned to the extracted keyword, the controller 180 may determine whether the sum of the scores exceeds a predetermined threshold. As a result of the determination, if the sum of the accumulated scores exceeds a predetermined threshold, it is determined that a schedule is detected from the message, and the controller 180 automatically generates a schedule based on the extracted keyword and schedules the schedule. You can register in the calendar.

Here, the controller 180 may determine the importance of the generated schedule based on the sum of scores. For example, if the total sum of scores is a large value, it can be determined as an important schedule. As such, when it is determined that the schedule is important, the controller 180 may register an indicator, which is distinguished from other schedules, for example, a star shape (level display may be possible depending on importance) and register it in the schedule calendar.

Herein, in order to determine the importance of the schedule based on the sum of scores, the controller 180 may preset an output range of messages for recognizing one schedule included in the output message. That is, the controller 180 extracts a keyword related to a schedule from messages exchanged during a specific time or for a specific period of time, and if a large number of keywords belonging to the same schedule are extracted during the corresponding time or during the specific period (that is, the corresponding schedule). If there are a lot of messages sent and received in connection with this), it can be judged as an important schedule.

On the other hand, when classifying the extracted keywords according to items, there may be a plurality of keywords belonging to one item.

As such, when there are a plurality of extracted keywords and a plurality of extracted keywords belong to one item, the controller 180 may select one representative keyword belonging to one item based on a predetermined priority. That is, the controller 180 may set one representative keyword for each item in the state in which the keywords are extracted.

Here, the predetermined priority may be determined according to the time when the keyword is extracted or the accuracy of information included in the extracted keyword. For example, a high priority may be given to a keyword extracted later among a plurality of keywords belonging to the item. Alternatively, a high priority may be given to a keyword including more information or more detailed information among a plurality of keywords belonging to the corresponding item.

Here, the representative keyword may be a keyword including the highest or most detailed information related to the corresponding item among the extracted keywords. For example, if a keyword belongs to a time item related to an event in the output message, and "Tomorrow" and "May 14 at 11:00" are extracted at the same time, the latter may include more detailed information. 14 days 11 o'clock may be extracted as a representative keyword of a time item.

On the other hand, in general, in the instant message or the SNS message, the final schedule is often checked once more, so the keyword extracted last among the keywords belonging to the corresponding item may be set as the representative keyword.

For example, referring to FIG. 5B, keywords belonging to a time item are 'keyword 1 and keyword 2', keywords belonging to a place item are 'keyword 3 to keyword 5', and keywords belonging to a topic item are 'keyword 6'. In this case, the controller 180 may set a keyword extracted last from each corresponding item, that is, 'keyword 2, keyword 5, keyword 6' as a representative keyword. In addition, if there is no keyword belonging to the corresponding item or there is only one keyword, there is no representative keyword or one extracted keyword is set as the representative keyword.

When the representative keyword is set in this way, the controller 180 may assign a score corresponding to the item only to the set representative keyword.

When the sum of scores assigned to each representative keyword exceeds a predetermined threshold score, it may be recognized as if a schedule is detected from the message. When the schedule is detected as described above, the controller 180 automatically generates a schedule based on the extracted keyword and registers it in the scheduling calendar.

Hereinafter, a method for recognizing a schedule related keyword from a message and detecting the schedule from the message will be described with reference to FIGS. 3 to 6.

In this regard, FIG. 6 is a conceptual diagram illustrating a method of outputting a notification message when automatically generating a schedule according to an embodiment of the present invention.

The electronic device 100 may output a message transmitted or received through the wireless communication unit 110 to the display unit 151, and extract at least one keyword related to a schedule from the output message.

Herein, a keyword related to a schedule may mean text including time information or place information.

When the keyword is extracted as described above, the controller 180 can assign a score to the extracted keyword based on a predetermined criterion. Here, score refers to a cumulative score for one extracted keyword or a plurality of keywords to be recognized as a meaningful 'schedule'. When a score is assigned to the extracted keyword, the controller 180 may determine whether the sum of the scores exceeds a predetermined threshold.

As a result of the determination, if the sum of the accumulated scores exceeds a predetermined threshold value, it may be determined that the schedule is detected from the message, and a schedule based on the extracted keyword may be generated.

As such, when a schedule based on the extracted keyword is generated, the controller 180 can control the display unit 151 to pop up a message indicating that the schedule has been created.

For example, referring to FIG. 6, when keywords related to a schedule are extracted from the received instant message 602 and recognized as a schedule according to a score calculation result, a schedule is generated in one area of the display unit 151. It is. Do you want to register as a schedule? 'Notification message 610 may pop up.

In this case, when the user pushes a key marked 'Yes', the schedule is registered on the corresponding date as shown in (b) of FIG. 4. At this time, the registered schedule, the attendees of the schedule, for example, the message sender 600 may be displayed. On the other hand, if the user pushes a key marked 'no', the generated schedule is canceled. In addition, although the form in which the notification message is displayed on the display is taken as an example, the present invention is not limited thereto. For example, the notification of automatic message generation may be output through the voice output module 152.

In the above, a method of automatically generating a schedule by extracting a keyword related to a schedule from a message has been described. Hereinafter, a method of displaying and editing an automatically generated schedule on a calendar will be described with reference to FIGS. 7, 8, and 11.

In this regard, FIGS. 7 and 8 are conceptual diagrams for describing a method of outputting a schedule calendar displaying an automatically generated schedule on a screen and a method of switching to another screen according to an embodiment of the present invention. 11 is a conceptual diagram illustrating a method for displaying confirmation of a schedule automatically registered in a calendar according to an embodiment of the present invention.

The electronic device 100 according to an embodiment of the present invention may extract at least one keyword related to a predetermined schedule from the message output to the display unit 151. When the keyword is extracted as described above, the controller 180 of the electronic device 100 may assign a score to the extracted keyword based on a predetermined criterion. When scores are assigned to the extracted keywords, the controller 180 may recognize that a schedule is detected from the message when the sum of the accumulated scores exceeds a predetermined threshold. When the schedule is detected as described above, the controller 180 automatically generates a schedule based on the extracted keyword and registers it in the scheduling calendar.

As described above, when a schedule is registered in a scheduling calendar, the registered schedule is displayed on an execution screen of the schedule calendar. Here, the execution screen of the schedule calendar may be displayed by executing a schedule calendar application through a user input, automatically executes a calendar calendar application when the transmission and reception of a message is finished, and always schedules on the initial screen of the electronic device 100. You can also display the calendar screen.

Meanwhile, when a new schedule is generated based on a keyword extracted from a message, it is necessary to distinguish between a case where a user confirms that the generated new schedule is registered in a scheduling calendar and a case where the user does not.

In detail, the controller 180 displays a first icon on the schedule calendar together with an object representing the created new schedule, and when the confirmation of the new schedule is detected, changes the first icon to a second icon. Can be displayed.

Here, the object may be at least one of text included in the generated new schedule and an image representing the same. The first icon means an indicator indicating a newly registered schedule, and the second icon means an indicator indicating a registration schedule for which a user has been confirmed. In addition, the second icon may include a case where the first icon is changed shape or the first icon disappears and there is no display.

For example, as illustrated in (a) of FIG. 11, when a new schedule extracted from a message is registered, a shape (first icon) 1110 of 'N' display may be displayed. The object 1140 indicating the new schedule may not be displayed initially but may be displayed when a touch on an area where the first icon is displayed is detected. As shown in FIG. 11B, the object 1140 may display, for example, date information 1141, content information 1142 of a schedule, and display of a previous / next schedule and / or registration of a new schedule. For example, an icon 1143 may be included. When the user confirms the registered schedule (for example, a touch on the area where the first icon is displayed), the controller 180 sets the shape 1110 of the 'N' display to the image of the 'star' display (second Icon) 1120 to display or disappear from the display unit 151 (not shown).

In addition, as described above, when the execution screen of the schedule calendar is displayed on the display unit 151, the controller 180 may display additional information related to the schedule when the first touch is applied to the region where the schedule is displayed. Can be. Here, the additional information is, for example, the author of the message, the time of creation or reception of the message, the type of message generated (e.g., auto-generated), or other information related to the schedule (maps about the place of the event, Person, schedule organizer, etc.). The first touch may be, for example, a short touch on an area in which a registered schedule is displayed (but is not limited thereto).

For example, referring to FIG. 7, when the first touch 710a is applied on the 11th day of displaying the schedule in the state where the schedule calendar of the display unit 151 is displayed, additional information related to the schedule and schedule registered on the corresponding day is displayed. 720 pops up. In the pop-up window 720, for example, 'automatic registration' is displayed as the schedule type 721, 'May 10' is displayed as the message reception time 722, and the 'Myeongrangrang' as the registered schedule 723. Appointment at 11 am.

In addition, when the execution screen of the schedule calendar is displayed on the display unit 151, the controller 180 controls to transmit the schedule information to an external electronic device when the second touch is applied to the region where the schedule is displayed. can do. Here, the second touch may be, for example, a long-touch or a flicking touch input in a predetermined direction for an area where a registered schedule is displayed (but not limited thereto).

For example, referring to FIG. 7, when the second touch 710b is applied on the 11th day of displaying the schedule on the display unit 151, the calendar is registered on the schedule calendar or the corresponding day of the calendar. An execution screen 730 of an email application having a schedule as an attachment file 740 may be displayed. According to another exemplary embodiment, only the contents related to the registered schedule may be transmitted to the selected external terminal.

In addition, when the execution screen of the schedule calendar is displayed on the display unit 151, the controller 180 includes a keyword which is a basis for generating the schedule when a third touch is applied to a region where the schedule is displayed. The message may be displayed on one area of the display unit 151. Here, the third touch may be, for example, a double-touch or a flicking touch input in a predetermined direction, but is not limited thereto.

As such, when a message including a keyword is displayed on the display unit 151 and a predetermined touch is applied to an area where the message is displayed, the controller 180 can switch the screen to the screen on which the message is output.

For example, referring to FIG. 8, when a double touch is applied to a region where a schedule is displayed while the execution screen 810a of the schedule calendar is output to the display unit 151, the execution screen 810a of the schedule calendar is displayed. ), A message screen 810b including a keyword based on generating a schedule may be displayed in a region in which) is reduced and a region is distinguished from the region. Meanwhile, although the message screen 810b is shown to be displayed in a right region distinct from the region where the execution screen 810a of the calendar is displayed, the message screen 810b may be displayed in the upper region, the left region, and the lower region, The display may overlap the execution screen 810a. When a touch is input in the area where the message screen 810b is displayed, the controller 180 switches the current screen to the execution screen 820 of the message application.

Although not shown in the drawings, the registered schedule may be deleted, a new schedule may be added, and a registered schedule may be changed through another touch input in a preset manner. To this end, when the fourth touch is applied to a region where a schedule is displayed, a list displaying the editing functions may be popped up on one region of the display unit 151.

In the above, the method of displaying and editing the schedule automatically generated by extracting the contents related to the schedule included in the message has been described. Hereinafter, a method of distinguishing between a schedule previously registered in a schedule calendar and an automatically generated schedule and a processing method at the time of a collision will be described.

The electronic device 100 according to an embodiment of the present invention may extract at least one keyword related to a predetermined schedule from the message output to the display unit 151. When the keyword is extracted as described above, the controller 180 of the electronic device 100 may assign a score to the extracted keyword based on a predetermined criterion. When scores are assigned to the extracted keywords, the controller 180 may recognize that a schedule is detected from the message when the sum of the accumulated scores exceeds a predetermined threshold. When the schedule is detected as described above, the controller 180 automatically generates a schedule based on the extracted keyword and registers it in the scheduling calendar.

As described above, when a schedule is registered in a scheduling calendar, the registered schedule is displayed on an execution screen of the schedule calendar. Here, the execution screen of the schedule calendar may be displayed by executing a schedule calendar application through a user input, automatically executes a calendar calendar application when the transmission and reception of a message is finished, and always schedules on the initial screen of the electronic device 100. You can also display the calendar screen.

As described above, while the execution screen of the calendar is displayed on the display unit 151, the controller 180 may be arbitrarily generated through a first schedule and a user input generated based on a keyword extracted from the message. An indicator for distinguishing a second schedule may be displayed on at least one of the first schedule and the second schedule.

For example, a first marker of a shape including a text and an image of 'child' is displayed together in the first automatically generated schedule, and a shape including a text and an image of 'any' is included in the randomly generated second schedule. The second indicator may be displayed together or not displayed at all.

Meanwhile, the controller 180 may edit the group of the first schedule generated automatically and the group of the second schedule randomly generated for each group. For example, it is possible to touch the indicator representing the first schedule so that the first schedules are displayed at once or selectively deleted.

In addition, as described above, while the execution screen of the calendar is displayed on the display unit 151, the controller 180 can arbitrarily generate a first schedule generated based on a keyword extracted from a message and a user input. When the generated second schedule collides, that is, when a new schedule is generated at the same time as the previously registered schedule, a notification message may be output to one area of the display unit 151. In such a case, the controller 180 updates the calendar with the selected schedule based on the selection signal by the user input.

In the above, the method of distinguishing between a schedule previously registered in a schedule calendar and a schedule automatically generated from a message and a processing method in case of a collision have been described. Hereinafter, a method of generating a schedule based on a user-selected keyword among keywords extracted from a message will be described with reference to FIGS. 9 and 10.

In this regard, FIG. 9 is a conceptual diagram illustrating a method of displaying a list of candidate keywords of a plurality of keywords extracted from a message and generating a schedule based on the selected candidate keywords according to an embodiment of the present invention. FIG. 10 is a conceptual diagram illustrating a method of generating a schedule based on a keyword input through a user input according to an embodiment of the present invention.

First, as described above, the electronic device 100 may extract at least one keyword associated with a predetermined schedule from the message output to the display unit 151. When the keyword is extracted as described above, the controller 180 of the electronic device 100 may assign a score to the extracted keyword based on a predetermined criterion.

On the other hand, when the extracted keywords are classified according to the above-described items related to the schedule (eg, a topic item, a time item, a place item, etc.), there may be a plurality of keywords belonging to one item.

As such, when there are a plurality of extracted keywords and a plurality of extracted keywords belong to one item, the controller 180 may select one representative keyword belonging to one item based on a predetermined priority. That is, the controller 180 may set one representative keyword for each item in the state in which the keywords are extracted.

Here, the predetermined priority may be determined according to the time when the keyword is extracted or the accuracy of information included in the extracted keyword. For example, a high priority may be given to a keyword extracted later among a plurality of keywords belonging to the item. Alternatively, for example, a high priority may be given to a keyword including more information or more detailed information among a plurality of keywords belonging to the corresponding item.

Here, the representative keyword may be a keyword including the highest or most detailed information related to the corresponding item among the extracted keywords.

As such, when the representative keyword is set, the controller 180 may generate a schedule based on the representative keyword set for each item.

On the other hand, a schedule generated based on a predetermined priority may be inaccurate or incorrectly generated. For example, if a keyword containing detailed information is given a high priority, and a representative keyword is set accordingly, for example, a message stating that it is difficult to meet at 3 pm today, we will meet tomorrow. Assume that it is received. Here, the text including time information '3 pm today' and 'tomorrow' including more detailed time information is the former, so '3 pm today' will be set as a representative keyword of the time item. Therefore, according to this, the wrong schedule can be registered. Thus, in the embodiment according to the present invention, if the generated schedule is displayed first, it is necessary for the user to check it and register it as it is or change.

Specifically, in a state where the item and the representative keyword belonging to the item are displayed on the display unit 151, when the first control signal is input, the controller 180 selects the representative keyword from the extracted plurality of keywords. A list of candidate keywords belonging to the item, except the list, may be popped up in one area of the display unit. Here, the first control signal means a control command for displaying a candidate keyword on the display unit. In addition, the candidate keyword means a keyword that is not a representative keyword among the keywords extracted from the message.

When a specific keyword displayed in the list is selected, the controller 180 can generate a schedule based on the selected candidate keyword.

For example, referring to FIG. 9, a new schedule is generated based on keywords extracted from transmitted and received instant messages 901, 902, and 903, and an item (eg, a topic, a time, a place) is displayed on the display unit 151. Etc.) and a new keyword 930 including a representative keyword belonging to the item (eg, “Meet Let's”, “11 AM tomorrow”, etc.). In a portion of the area where the representative keyword is displayed, a key 935 of the candidate can be displayed for each item. When a touch on a specific 'candidate' key 935 "is input through the user input, a list 940 of candidate keywords excluding representative keywords of the corresponding item is displayed. In the displayed list 940, the user selects a specific candidate keyword (eg , 'Tomorrow') changes the keyword of the corresponding item ('11 AM tomorrow ') to the selected candidate keyword (' Tomorrow '), that is, a schedule based on the selected candidate keyword is generated. The user may register the changed schedule in the schedule calendar through a predetermined key input or voice command.

In addition, in a state in which the item and the representative keyword belonging to the item are displayed on the display unit 151, when the second control signal is input, the controller 180 is associated with the schedule belonging to the item through a user input. An input area for receiving at least one keyword may be displayed on one area of the display unit. Here, the second control signal refers to a control command for displaying a predetermined input area (and keys for input) on the display unit.

When predetermined text is input to the displayed input area, the controller 180 may generate a schedule based on the keyword input to the input area.

For example, referring to FIG. 10, a new schedule is generated based on keywords extracted from transmitted and received instant messages 901, 902, and 903, and an item (eg, a topic, a time, a place) is displayed on the display unit 151. Etc.) and a new keyword 930 including a representative keyword belonging to the item (eg, “Meet Let's”, “11 AM tomorrow”, etc.). In one region of the region 930 where a schedule is displayed, an 'input window' key 937 for receiving a control command for displaying an input region may be displayed. When a user applies a touch to the 'input window' key 937, for example, at least one input window 950 may be displayed in an area where a representative keyword of an item is displayed. In the input window 950, a representative keyword is initially displayed. However, if a short touch is applied to a corresponding area, the representative keyword disappears and the user may input a new keyword with input keys. When the input is completed, a touch is applied to the 'confirmation' key 960 to generate a schedule based on the input keyword.

In addition, the controller 180 may generate a schedule through at least one combination of the representative keyword, the candidate keyword, and a keyword input through a user input.

On the other hand, when the schedule is generated in this way, it is possible to implement so that the user selects to automatically register the generated schedule to the schedule calendar and to be registered by the user.

To this end, the user input unit 130 of the electronic device 100 according to an embodiment of the present invention inputs a control command for executing at least one of an automatic registration mode and a manual registration mode that change whether or not the generated schedule is automatically registered. I can receive it.

In the automatic registration mode, when a schedule is generated, the controller 180 can automatically register the generated schedule with the schedule calendar within a preset time. Here, the predetermined time may be 'immediately after generating a schedule' or 'after a predetermined time' elapses after the schedule is generated (for example, after 1-2 hours).

Meanwhile, in the manual registration mode, the controller 180 may display the generated schedule on the waiting list of the calendar to register the user through a user input. Schedules displayed in the waiting list may be deleted when a preset time (eg, one week) is exceeded.

As described above, according to the electronic device and the schedule automatic generation method of the electronic device according to an embodiment of the present invention, if a message associated with a schedule is included in the message transmitted and received through the electronic device, the extracted keyword is extracted and extracted. When the keyword is recognized as a schedule, a user's convenience may be provided by automatically creating a schedule and registering the calendar.

In addition, according to one embodiment disclosed herein, the above-described method may be implemented as code that can be read by a processor in a medium in which a program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The electronic device described above is not limited to the configuration and method of the above-described embodiments, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications may be made. It may be.
