The touch pad 16 is installed so as to cover the display screen of the display unit 15 and constitutes a touch panel together with the display unit 15.

  FIG. 2 is a block diagram showing a detailed configuration of the related page search unit 20. The related page search unit 20 includes a related page search management unit 21 that manages each unit in the related page search unit 20, a browser cooperation unit 22 connected to the control unit 11 and the browser unit 17, a text region extraction unit 23, A dictionary 24 for morphological analysis, a keyword extraction unit 25, a keyword storage unit 26, a search query generation unit 27 connected to the mobile communication network transmission / reception unit 13, and a search result connected to the mobile communication network transmission / reception unit 13. The analysis unit 28 includes a UI input / output unit 29 connected to the display unit 15 and the touch pad 16. In FIG. 2, the signal flow is indicated by a solid line with an arrow, and the stored information is indicated by a broken line with an arrow. The directions of these lines and arrows are understood for the operation of each part. It does not show all signal flows and information references.

  The operation of each part of the mobile communication apparatus configured as described above according to the embodiment of the present invention will be described with reference to FIG. 1 and FIG. The mobile communication network communication unit 12 transmits the high frequency signal transmitted from the base station and received by the antenna 12a to the mobile communication network transmission / reception unit 13, and the high frequency signal transmitted from the mobile communication network transmission / reception unit 13 is transmitted to the antenna 12a. To the base station.

  The mobile communication network transmission / reception unit 13 amplifies, converts and demodulates a high frequency signal from the mobile communication network communication unit 12, and transmits a digital voice signal to the call unit 14, a control signal to the control unit 11, and a web page. The signal is transmitted to each unit of the apparatus via the control unit 11.

  The mobile communication network transmission / reception unit 13 further receives a digital voice signal transmitted from the call unit 14, a control signal transmitted from the control unit 11, and a web page access signal transmitted from each unit of the apparatus. Modulation, frequency conversion and amplification are performed to obtain a high frequency signal, which is sent to the mobile communication network communication unit 12.

  The calling unit 14 converts the digital audio signal transmitted from the mobile communication network transmitting / receiving unit 13 into an analog audio signal, amplifies it, and sends it to the speaker 14a. In addition, the analog audio signal transmitted from the microphone 14 b is amplified, converted into a digital audio signal, and transmitted to the mobile communication network transmitting / receiving unit 13.

  The display unit 15 is an organic EL display used for display for prompting the user to operate, display of the contents operated by the user, display of the operation state of the apparatus, etc. By including the program and being controlled by the control unit 11 and each part of the apparatus, image data including characters, numbers, and icons is displayed. Also, image data for identifying the operation is displayed.

  The touch pad 16 includes an element for detecting contact and a driver program. When a finger or the like is touched for a predetermined time, the touch pad 16 detects the touch. The method for determining whether or not the touch pad 16 is touched may be a pressure-sensitive type that senses a change in pressure, or a capacitance type that detects a change in capacitance with a finger or the like. Other methods may be used. When contact is detected, the touch pad 16 transmits coordinates indicating the touched position to the control unit 11. In addition, when each part of the apparatus requests notification of the coordinates, a coordinate indicating a position touched to the part is transmitted instead of the control part 11.

  The touch pad 16 constitutes a touch panel together with the display unit 15. Therefore, when a finger or the like touches the position of the display screen of the display unit 15 on which the image data is displayed, the coordinates of the position are transmitted, and each unit of the apparatus that has received the coordinates is identified by the image data. By performing the operation, it is possible to provide an easy-to-understand user interface for the user of the apparatus. For example, when a position where an image for identifying a processing unit of the apparatus is displayed is touched, the processing unit is activated. In addition, when a QWERTY-type keyboard is displayed and each key is touched at the displayed position, a character identified by the key is input. In this way, an input operation by the user of the apparatus is performed by the touch pad 16.

  Therefore, hereinafter, the contact of the finger or the like with the touch pad 16 is referred to as an input operation from the touch pad 16. The contact is referred to as touch. Further, an image in which an input operation is performed by touching a position where the image is displayed, such as the image data, is referred to as a soft key. The keyboard displayed for character input is referred to as a soft keyboard. Note that an image that is not input by touching the displayed position is not a soft key.

  The key input unit 16a includes operation keys pressed by the user. When the operation key is pressed, the key input unit 16a notifies the control unit 11 of the identifier of the key. The operation keys include keys for inputting limited instructions such as a power ON / OFF key, a volume adjustment key during a call, a call incoming / outgoing call, and a call end key.

  The browser unit 17 starts operation by an input operation from the touch pad 16 or the key input unit 16a, and accesses a web page identified by a predetermined URL. Then, still images and moving images and characters included in the web page are displayed on the display unit 15, and sound is generated from the speaker 14a or the second speaker for generating sound.

  Further, when a URL is designated by an input operation from the touch pad 16, the browser unit 17 accesses a web page identified by the URL. Furthermore, according to the touch on the position where the link is displayed, the web page identified by the URL associated with the link is accessed. The browser unit 17 ends the operation by an input operation from the touch pad 16 or the key input unit 16a.

  The related page search management unit 21 starts the operation based on an instruction from the browser cooperation unit 22 triggered by the browser unit 17 starting the operation. Then, based on the input operation from the touch pad 16 notified via the UI input / output unit 29, the keyword extracted by the keyword extracting unit 25 is specified, and the search query generating unit 27 is controlled to display the web on the search site. Search for a page.

  Then, the related page search management unit 21 causes the search result analysis unit 28 to analyze the search result. Then, a list of analyzed search results is displayed on the display unit 15 via the UI input / output unit 29. Further, the URL of the search result selected based on the input operation from the touch pad 16 notified via the UI input / output unit 29 is notified to the browser unit 17 via the browser cooperation unit 22 and the URL is accessed. Let

  The browser cooperation unit 22 is a plug-in to the browser unit 17, starts operation when the browser unit 17 starts operating, and immediately activates the related page search management unit 21. The message from the control unit 11 to the browser unit 17 is set to be received instead of the browser unit 17. Then, the received message is transmitted to the browser unit 17 and transmitted to the related page search unit 20. Here, the message includes a control signal to the browser unit 17 and web page data (html file) downloaded by the browser unit 17. Further, the browser cooperation unit 22 receives an event in the browser unit 17, transmits the event to the related page search unit 20, further acquires data in the browser unit 17, and acquires the data in the related page search unit 20. Send in.

  An example of a method in which the browser cooperation unit 22 receives a message from the control unit 11 to the browser unit 17 instead of the browser unit 17 will be described. When the control unit 11 calls a function belonging to the browser unit 17 and the message is transmitted via the callback function, the browser cooperation unit 22 replaces the function belonging to the browser unit 17 with the browser cooperation unit 22. The address of the function referred to by the control unit 11 is rewritten so that the control unit 11 calls the function belonging to. Then, the message is received via the callback function, and the message is transmitted to the browser unit 17 instead of the control unit 11. By this operation, the message can be used in the related page search unit 20 without affecting the operation of the browser unit 17.

  The control signal from the control unit 11 to the browser unit 17 received by the browser cooperation unit 22 is an instruction to access a web page specified by the URL. In addition, the events in the browser unit 17 received by the browser cooperation unit 22 are the start of downloading a web page, the end of downloading, and the like. The browser cooperation unit 22 notifies the related page search management unit 21 of these control signals and events. When the browser cooperation unit 22 receives a download completion notification from the browser unit 17, the browser cooperation unit 22 acquires the downloaded web page data from the browser unit 17. Then, the data is transmitted to the text area extraction unit 23, and after the text area extraction unit 23 and the keyword extraction unit 25 are sequentially operated, the related page search management unit 21 is notified of the end of the operation.

  The browser cooperation unit 22 transmits a message to the browser unit 17 instead of the control unit 11. This message is a control signal for instructing access to the web page specified by the URL. This URL is notified from the related page search management unit 21 to the browser cooperation unit 22.

  The text area extraction unit 23 starts an operation in accordance with an instruction from the browser cooperation unit 22 and extracts a text from the web page transmitted from the browser cooperation unit 22. That is, since the web page is described in the html language, a character string other than the text such as a tag, an advertisement, the name of the person who operates the website, and a table of contents is removed from the character string to obtain a text. The text and non-text are determined by, for example, a character string statistic including a character type. The text area extracting unit 23 transmits the extracted text to the keyword extracting unit 25.

  The keyword extraction unit 25 starts the operation according to the instruction of the browser cooperation unit 22, extracts one or a plurality of keywords from the text extracted by the text region extraction unit 23, and assigns a score to each of the extracted keywords. The keyword storage unit 26 stores the information and notifies the browser cooperation unit 22 of the completion of keyword extraction. That is, first, the text is analyzed with reference to the dictionary 24. Among the obtained morphemes, a morpheme that satisfies all of the following conditions or a part of the following conditions more is set as a keyword, and the number of conditions that are satisfied is set as a score.

  To illustrate the conditions, first, it is stored in the dictionary 24, second is stored as a noun, third is stored as a proper noun, and fourth is a name. It is remembered that there is, 5th appears at the beginning of the text, 6th it appears many times in the text, 7th is the type of morpheme character (Kanji, Hiragana, Katakana, or , Any alphabetic character or combination).

  Eighth, the words are stored in the related page search unit 20. This word is stored in accordance with the user's input operation according to the user's preference. The dictionary 24 stores semantic attributes in association with morphemes, and when the apparatus stores user preferences, the ninth condition is that the user preferences and semantic attributes are closely related. That is. When semantic attributes are stored in the dictionary 24, the keyword extraction unit 25 adds the semantic attributes associated with the extracted keywords to the keyword storage unit 26 and stores them.

  The user's preference includes, for example, sports, soccer, music, jazz, and the like, but includes user attributes such as sex, age, address, and the like. When the semantic attributes stored in the dictionary 24 are broad concepts compared to tastes such as music and sports, for example, a thesaurus that soccer is included in sports is also stored in the dictionary 24, and soccer and sports are It is said that there is a close relationship. The user's preference may be stored in the related page search unit 20 or may be stored in the control unit 11 as a part of information related to the user.

  Note that conditions opposite to those described above may be used. For example, it is expected to be a morpheme but is not stored in the dictionary 24, is not a proper noun, has a small number of occurrences in the text, and has a predetermined range of relationships between user preferences and semantic attributes.

  Also, scoring is not limited to one. Some of the above-described conditions may be different. In addition, the condition may be weighted, and the score may be the sum of the weights for each condition that is satisfied. When a plurality of scoring is performed, a plurality of sets of keywords are stored in the keyword storage unit 26 along with the conditions under which the score is assigned to each set.

  The search query generation unit 27 starts to operate according to an instruction from the related page search management unit 21, receives a category and a keyword related to web page search from the related page search management unit 21, and sets the mobile communication network transmission / reception unit 13. Via the search site connected to the Internet.

  In addition, when a plurality of keywords are received, another search is performed for each keyword. However, a plurality of keywords may be collected and searched for each collected keyword. When keywords are collected, the number of searches can be less than the number of received keywords, at least once, and the search time can be shortened. Further, the search site may be a device that searches a web page by being given a keyword, and may be a device in which the searched web page is limited to a page stored in the device of the search site. In addition, the apparatus is not limited to the page.

  In this search, the search site is determined by any of the following or a combination of a plurality of search sites. In addition, when searching for each grouped keyword, the following criteria are applied to each grouped keyword. If different decisions are made according to each of those keywords, the decision with more individual keywords is taken as the decision for the combined keywords.

  First, a search site associated with each category is used. This association is stored in the search query generation unit 27. Second, when a semantic attribute is attached to a keyword, a search site associated with each semantic attribute is used. This association is stored in the search query generation unit 27. Third, a search site associated with the preference of the user of the device is used. This association is stored in the search query generation unit 27. Fourth, the number of times the user of the device has instructed access to a web page searched by a search site in the past is stored in the related page search unit 20 for each search site, and a search site with a large number of times is selected. .

  The search result analysis unit 28 receives a search result of a search performed according to an instruction from the search query generation unit 27. This search result indicates a web page, and includes a title, a snippet, and a URL. One or a plurality of search results can be obtained for one search, and the search result may not be obtained. is there. The search result analysis unit 28 analyzes each search result obtained for one search, and selects at least one useful for the user of the apparatus from the search results.

  This selection criterion is any one or a combination of the following. First, when the search site sends the search results with rankings, the search results of the first ranking are selected. This is because the ranking by the search site is considered to be grounded.

  Secondly, it depends on the degree of similarity with the text from which the keyword specified in the search is extracted, that is, the text extracted by the text area extraction unit 23. The similarity is, for example, the ratio of the morpheme (or character string) included in the title and snippet and the morpheme (or character string) included in the text. The morpheme is analyzed with reference to the dictionary 24 as described in the explanation of the operation of the keyword extraction unit 25. Then, a search result whose similarity is within a predetermined range is selected. That is, a search result whose similarity is larger than the maximum similarity threshold and a search result smaller than the minimum similarity threshold are not selected.

  This is because a high degree of similarity is not useful because the content of the web page obtained by the search is similar to the content of the web page displayed by the browser unit 17 and includes the exact same text. Because. The small degree of similarity is because the content of the web page obtained by the search is not useful because it may be far from the content of the web page displayed by the browser unit 17.

  Third, a search result that matches the preference of the user of the device is selected. That is, a search result having a close relationship between the semantic attribute stored in the dictionary 24 in association with the morpheme included in the title and snippet and the user's preference is selected.

  When the number of characters in the selected search result snippet exceeds a predetermined snippet character count threshold, the search result analysis unit 28 shortens the snippet within the threshold. At the time of this shortening, the keyword specified in the search is made to appear at least once in at least one of the title and the snippet. Also, a predetermined number of characters before and after the keyword are not deleted as much as possible. This is so that the contents of the selected search result can be easily understood.

  In this way, the search result analysis unit 28 selects at least one search result for every search result of all searches, and if necessary, shortens the snippet and searches all the selected search results for related pages. Transmit to the management unit 21. Alternatively, it is transmitted every time the selected search result is obtained.

  As described above, the search query generation unit 27 performs a web page search for each keyword extracted by the keyword extraction unit 25, and the search result analysis unit 28 selects at least one search result for each search. Therefore, at least one search result is obtained for each extracted keyword, and the extracted keyword is included in the title or snippet of at least one selected search result even if the snippet is shortened. None of the keywords are buried and appear in search results.

  The UI input / output unit 29 causes the display unit 15 to display in accordance with an instruction from the related page search management unit 21. When this display is a soft key, the coordinates of the range of the position to be displayed are specified, and when there is a touch on the coordinates, the touch pad 16 is requested to be notified. When a notification indicating that a touch has been made is received from the touch pad 16 in accordance with this request, the UI input / output unit 29 notifies the related page search management unit 21 of information for identifying the touched soft key, for example, coordinates. To do.

  When there is an instruction to display a different soft key from the related page search management unit 21, the UI input / output unit 29 designates a range of positions to be displayed by the new soft key and performs the above operation on the touch pad 16. Make a request. Further, when there is an instruction to erase the display of the soft key from the related page search management unit 21, the above request is canceled with respect to the touch pad 16.

  Next, with reference to the flowcharts shown in FIGS. 3 and 4, the operation of the related page search management unit 21 for controlling the search for a web page related to the web page accessed by the browser unit 17 will be described. In this description, the transition of the screen displayed on the display unit 15 will be described together.

  The related page search management unit 21 is activated by the browser cooperation unit 22 that has started operating when the browser unit 17 starts operating (step S21a). 5 and 6 show the transition of the screen displayed on the display unit 15 by the operation of the related page search management unit 21, and FIG. 5A shows the screen when the related page search management unit 21 starts the operation. Indicates.

  This screen includes a URL field 15a and a browser part display field 15b. This screen is a screen immediately after the browser unit 17 is activated. The URL column 15a displays the URL of the web page that the browser unit 17 accesses when the operation starts, and the browser unit display column 15b displays the URL. Nothing is displayed.

  Note that the URL field 15a and the browser part display field 15b are always displayed by the browser part 17 when the browser part 17 is operating, so that they are always displayed when the related page search management part 21 is operating. In addition to these, a title bar and a menu bar are displayed by the browser unit 17, and basic command soft keys and pictographs including an incoming call key and an end call key are displayed by the control unit 11. Since it does not change depending on the operation of the page search management unit 21, the illustration is omitted.

  The related page search management unit 21 determines whether a notification that a web page download start event has occurred in the browser unit 17 from the browser cooperation unit 22 is received (step S21b). Continue stepping. On the other hand, if received, the UI input / output unit 29 is instructed to display the function non-operation icon 15c on a part of the browser part display field 15b as shown in FIG. 5B (step S21c). This display informs that the download has started.

  In this step, the browser unit 17 has not finished downloading the web page, and the related page search management unit 21 cannot search for a web page related to the web page accessed by the browser unit 17. Therefore, the function non-operation icon 15c is displayed in the first display form in order to indicate that the related page search management unit 21 is in operation but cannot perform processing based on the input operation of the user of the apparatus. , Not a soft key. Here, the first display form is a plain display, for example, a gray display.

  Whether the related page search management unit 21 receives a notification from the browser cooperation unit 22 that a web page download end event has occurred in the browser unit 17 and that the keyword extraction by the keyword extraction unit 25 has been completed. (Step S21d), if not received, the operation of this step is continued. On the other hand, when received, as shown in FIG. 5C, the UI input / output unit 29 is instructed to replace the function non-operation icon 15c with the function active icon 15d in a part of the browser portion display field 15b. (Step S21e). By this display, the download is completed, and the related page search management unit 21 is informed that the function is operating by touching the function operating icon 15d.

  As already described, the text region extraction unit 23 and the keyword extraction unit 25 operate based on an instruction from the browser cooperation unit 22 when a web page download end event occurs in the browser unit 17. . This is because keyword extraction becomes possible as the download ends, and control of the related page search management unit 21 is unnecessary. However, the present invention is not limited to this, and the browser cooperation unit 22 notifies the related page search management unit 21 that a download end event has occurred, and the related page search management unit 21 detects the text area extraction unit 23 and the keyword extraction unit 25. May be operated.

  On the screen shown in FIG. 5C, the browser part display field 15b displays the contents of the web page including the scroll bar by the browser part 17. The function operating icon 15d is a soft key displayed in a second display form different from the first display form in order to prompt a touch. Here, the second display form is a display that is conspicuous as compared with the first display form and that does not become noticeable when browsing the display by the browser unit 17, for example, a purple display. The first display form and the second display form are display forms that can be clearly identified by the user of the apparatus.

  Furthermore, since the UI input / output unit 29 is notified that the function operating icon 15d is a soft key, a touch on the function operating icon 15d is notified to the related page search management unit 21 via the UI input / output unit 29. The browser unit 17 is not notified via the control unit 11. Conversely, touches on the browser part display field 15b other than the function active icon 15d are not notified to the related page search management part 21, but are notified to the browser part 17 and displayed on the browser part display field 15b. The contents are scrolled.

  The operations up to step S21e are performed without an input operation from the touch pad 16 and the key input unit 16a, and the related page search unit 20 gives the user of the apparatus an impression that it is a part of the browser unit 17. . Therefore, the user can easily try searching for a web page. Further, the operation so far does not involve communication via the mobile communication network communication unit 12. Therefore, there is no power consumption by the communication.

  The related page search management unit 21 determines whether or not the function operating icon 15d has been touched by a notification from the UI input / output unit 29 (step S21f), and if not touched, continues the operation of this step. When touched, the UI input / output unit 29 is instructed, and as shown in FIG. 5D, the operation menu 15e including a plurality of categories as soft keys is arranged in a row or column with the function active icon 15d. Is displayed on a part of the browser section display field 15b (step S21g). This display informs the user that the related page search management unit 21 searches for a web page corresponding to the category by touching any category in the operation menu 15e.

  Here, the image of the function operating icon 15d, which is a soft key, is illustrated so as not to change, but the image may be changed according to the operation step. This is because, when the display shown in FIG. 5C is displayed by the operation of step S21e, the function active icon 15d indicates that the related page search management unit 21 can start the operation of causing the search site to search for the web page. Show. However, in operation steps other than step S21e including step S21g, the operation of the related page search management unit 21 may be returned to the previous stage by touching the function operating icon 15d. For example, “x”, “ This is because a display such as “return” helps the user to understand intuitively.

  The operation menu 15e illustrated in FIG. 5D includes five categories of “dictionary”, “moving image”, “breaking news”, “topic”, and “reputation”. When touched, the search query generation unit 27 performs a search using a search site excellent for searching web pages of bulletin boards such as encyclopedias, movies, news, blogs, and reviews.

  There are no restrictions on the category, such as “Dictionary”, “Map”, “Weather”, etc., for obtaining more detailed information, “Video”, “Image”, “Game”, etc. To obtain reference information on user behavior, such as “eating”, “travel”, “buying”, uploading information such as “bulletin board”, “rental”, There are things such as “work”, “byte”, etc. for searching for businesses. When the number of categories is large, the operation menu 15e has a plurality of levels, and in the first level, a purpose such as to obtain information, to enjoy, to obtain action reference information is selected, and the second level In the hierarchy, a category belonging to the selected purpose may be selected.

  Here, when “Map” is touched, a search using a search site excellent for searching a web page of a map is performed. When “weather” is touched, a search using a search site excellent for searching a weather forecast web page is performed.

  Furthermore, when “eating” is touched, for example, a search using a search site excellent for searching a restaurant web page or a search site excellent for searching a recipe web page is performed. When “travel” is touched, for example, a search using a search site excellent for searching a map web page or a search site excellent for searching a web page for weather forecast is performed. Further, when “buy” is touched, for example, a search using a search site excellent in searching a web page of a store or a search site excellent in searching a web page of an Internet auction site is performed.

  The categories included in the operation menu 15e include keywords extracted by the keyword extraction unit 25 (including attached semantic attributes), user preferences of the device, conditions used for keyword scoring, Or you may select according to the weighting to the conditions. For example, when a dish name is extracted, the category “eat” is selected. In addition, if the preference is eating, regardless of the extracted keyword, the category “eating” is selected.

  In addition, if it is a proper noun, or if it is weighted, it is preferable to select a category such as “breaking news”, “topic”, and “reputation”, and a category “dictionary” is preferable. Absent. This is because proper nouns, especially personal names, are often not listed in encyclopedias. In addition, the category “dictionary” is preferably selected on the condition that it is expected to be a morpheme but is not stored in the dictionary 24 or when the condition is weighted. This is because a detailed explanation of the keyword described in the encyclopedia is considered useful for the user of the apparatus.

  The related page search management unit 21 determines whether or not the touch pad 16 has been touched by a notification from the UI input / output unit 29 (step S21h). Continue to work. On the other hand, when any of the categories in the operation menu 15e is touched, the UI input / output unit 29 is instructed to display the searching display 15f instead of the operation menu 15e as shown in FIG. Is displayed in a part of the browser part display field 15b, and the search query generating part 27 and the search result analyzing part 28 are operated (step S21i). This display during search 15f is not a soft key, and this display displays on the display unit 15 that a web page is being searched. In addition, although it has shown in figure that the display 15f in search includes the display of the touched category, it does not need to be included.

  When the function operating icon 15d is touched while the search display 15f is displayed, the related page search management unit 21 ends the operation of the search query generation unit 27 and / or the search result analysis unit 28. This interrupts the search site to search the web page, instructs the UI input / output unit 29 to delete the searching display 15f, moves to step S21e, and displays the display unit 15 in FIG. Is displayed (not shown). Or it moves to step S21g and the display shown in FIG.5 (d) is displayed on the display part 15 (not shown). By this touch, the user of the apparatus can instruct to interrupt or redo the operation of causing the search site to search for the web page.

  Further, when operating the search query generation unit 27, the related page search management unit 21 uses the keyword determined to be extracted in step S21d and the category determined to be selected by touch in step S21f as the search query. The data is transmitted to the generation unit 27. The keywords are given a score and stored in the keyword storage unit 26, and a predetermined number of keywords having higher scores are selected and transmitted.

  In addition, when the semantic attribute is attached | subjected to the keyword, the related page search management part 21 depends on the selected category in addition to or instead of having a high score, A keyword with a semantic attribute to be determined may be selected. In addition, as a result of a plurality of scoring, when a plurality of sets of keywords are stored using any condition or with a weight attached to the condition, the related page search management unit 21 selects Depending on the category, a set of keywords is selected, and a keyword to be transmitted is selected from the keywords included in the set.

  An example of selecting a keyword with reference to the selected category and the semantic attribute is to select a keyword that is a brand name when the category “buy” is selected. When the category “eat” is selected, a keyword that is a dish name is selected. When the category “map” is selected, a keyword that is a place name is selected.

  In addition, an example of selecting a keyword set with reference to the selected category is that when the category “buy” is selected, the keyword set extracted by using a proper noun or weighted is used. Is to choose. When the category “map” is selected, it is a proper noun, in particular, a place name, or a combination of keywords extracted by weighting is selected.

  Returning to the description of the operation for controlling the search of the web page by the related page search management unit 21 with reference to FIG. The related page search management unit 21 determines whether or not the search result transmitted from the search result analysis unit 28 has been received (step S21j). If not received, the operation of this step is continued. When one or more search results are received, the UI input / output unit 29 is instructed to erase the function operating icon 15d and the search in progress display 15f, which are soft keys as shown in FIG. 6B. A return instruction display 15g and a search result display 15h, which is a soft key, are displayed in the browser section display field 15b (step S21k). The number of displayed search result displays 15h is the number of received search results. The search result display 15h includes display of titles, snippets, and URLs included in the search results.

  For example, when the searched web page includes an image, the search result may include a thumbnail image or a URL where the thumbnail image is stored. In this case, the related page search management unit 21 searches the thumbnail image received via the search result analysis unit 28 or the thumbnail image received by accessing the URL received via the search result analysis unit 28. It is included in the result display 15h and displayed on the display unit 15 as shown in FIG. The display in FIG. 7 is obtained by adding a thumbnail image to the display in FIG.

  The thumbnail image is displayed so as to overlap with the browser section display field 15b. For this reason, it may be necessary to perform processing in which the thumbnail image is not disturbed due to the display in the browser section display field 15b. For example, specific colors included in the thumbnail image, for example, colors represented as 0, 0, and 0 by the three primary colors R, G, and B, are transmitted through the display of the browser display column 15b under the control of the control unit 11. , The related page search management unit 21 replaces the color with a similar color in which the three primary colors R, G, and B are represented as 4, 4, 4, and the like.

  The related page search management unit 21 determines whether or not the touch pad 16 has been touched by a notification from the UI input / output unit 29 (step S21m), and if not touched, continues the operation of this step. On the other hand, when any one of the search result displays 15h is touched, the URL included in the touched search result display 15h is notified to the browser unit 17 via the browser cooperation unit 22 and accessed (step S21n).

  Then, the related page search management unit 21 instructs the UI input / output unit 29 to delete the return instruction display 15g and the search result display 15h (step S21o), and proceeds to the operation of step S21b. Here, the browser unit 17 erases the contents of the web page displayed in the browser unit display field 15b when a new access to the web page is instructed.

  Therefore, although the content displayed in the URL field 15a is different on the display unit 15, the display shown in FIG. 5A is displayed, and this display is related to the related page in step S21a as the operation of the browser unit 17 starts. The display is the same as when the search management unit 21 starts operation. That is, the display transition already described with reference to FIGS. 5 and 6 occurs with the operation after step S21b.

  For example, when it is determined in step S21b that the download of the web page identified by the URL notified in step S21n is started, the function non-operation icon 15c shown in FIG. 5B is displayed. When it is determined in step S21d that the download has been completed and the keyword has been extracted from the web page, the contents of the web page and the function active icon 15d are displayed as shown in FIG. Is done. This display is the same as the display shown in FIG. 5C, although the content displayed in the URL column 15a and the content displayed in the browser unit display column 15b are different, and the related page search management unit 21 is the same. Corresponds to being in an operational step.

  When the return instruction display 15g is touched in step S21m, the related page search management unit 21 instructs the UI input / output unit 29 to delete the return instruction display 15g and the search result display 15h (step S21p). The process moves to S21e. At this time, as a result of the operation in step S21p, the display shown in FIG. Or it moves to step S21g and the display shown in FIG.5 (d) is displayed on the display part 15 (not shown).

  If it is determined in step S21j that there is no search result, that is, 0 is received, the related page search management unit 21 instructs the UI input / output unit 29 to delete the search-in-progress display 15f. As shown in (d), the no-search-result display 15i is displayed over a predetermined search-result-notifying notification time to notify that there is no search result (step S21q), and the process proceeds to step S21e. At this time, the display shown in FIG. Or it moves to step S21g and the display shown in FIG.5 (d) is displayed on the display part 15 (not shown). The no search result display 15i is not a soft key.

  If the function active icon 15d is touched while the no search result display 15i is displayed, the related page search management unit 21 instructs the UI input / output unit 29 to erase the no search result display 15i. Then, the process proceeds to step S21e, and the display shown in FIG. 5C is displayed on the display unit 15 (not shown). Or it moves to step S21g and the display shown in FIG.5 (d) is displayed on the display part 15 (not shown). By this touch, the user of the apparatus can instruct the search site to redo the operation of searching for a web page.

  When the function operating icon 15d is touched in step S21h, the related page search management unit 21 instructs the UI input / output unit 29 to delete the operation menu 15e (step S21r), and proceeds to step S21e. At this time, as a result of the operation in step S21r, the display shown in FIG.

  As described above, the related page search unit 20 performs not only keyword extraction by the keyword extraction unit 25 but also category selection displayed in step S21g by the related page search management unit 21, and keywords transmitted to the search query generation unit 27 in step S21i. Selection of a search site by the search query generation unit 27, selection of a search result by the search result analysis unit 28, and many operations, for example, an operation according to the preference of the user of the apparatus can be performed. it can. As a result, even if the web page accessed by the browser unit 17 is the same, the web page searched by the related page search unit 20 is not necessarily the same, and a web page useful for the user of the apparatus is searched.
