In order to eliminate such inconvenience, a table of contents or a headline is added as a menu content in advance to the mail to be distributed, and what information content is included simply by looking at the menu content is simply displayed. There may be.
However, even in this case, it may take time to reach the target information. For example, even if the information you want is included in the delivered mail, if that information is listed at the end of the long mail, the user will end up scrolling down to reach the desired information. Inevitably, it took a lot of time to do so.

  On the other hand, keywords are extracted from plain text, the document structure is determined, link targets are selected from the extracted keywords and document structure, and link information for the table of contents and text is automatically created for the user to view. Conventionally, there is a method for making it easy (see, for example, Patent Document 1).

A. Configuration (1) Appearance of Mobile Phone 10 and Network System Configuration FIG. 1 is a perspective view of a mobile phone 10 according to an embodiment of the present invention and a partially enlarged view thereof. The cellular phone 10 includes a display unit 11 and an operation unit 12 as illustrated. The display unit 11 allows the user to browse a document acquired by the mobile phone 10 (see an enlarged view). The operation unit 12 includes a plurality of keys such as a numeric keypad.
The mobile phone 10 also exchanges radio waves with a base station connected to the mobile phone network via an antenna ANT (see FIG. 2). The cellular phone network is connected to the Internet network via a gateway server, and various service centers are connected to the Internet network. Through such a well-known network system (not shown), the mobile phone 10 can receive mail distributed by various service centers.

(2) Internal Configuration of Mobile Phone 10 Next, the configuration of the mobile phone 10 will be described with reference to FIG. In FIG. 2, the CPU 100 controls the operation of each unit of the apparatus based on various programs stored in the ROM 101 in accordance with a signal supplied from the operation unit 12 or the like.
The ROM 101 includes a program area and a data area. Various programs executed by the CPU 100 are stored in the program area of the ROM 101. The various programs herein include an application program that performs a main routine, title portion candidate character number determination processing, document storage processing, and the like, which will be described later. In the data area of the ROM 101, in addition to control data referred to by a predetermined program, various screen data forming a standby screen, for example, are stored.
The CPU 100 and the ROM 101 integrally realize the functions of an extraction unit, a position specification unit, an allocation unit, a link information table creation unit, and a link display control unit.

The RAM 102 includes a link information table storage unit 102a and a link information table-added document storage unit 102b.
The link information table storage unit 102a includes link information tables (1) -0, (1) -1 and (1) -2 shown in FIG. 3, which will be described later, and link information tables (2) -1 and (2) shown in FIG. ) -2 is stored. These various link information tables will be described in detail in the description relating to the operation of the present invention.
The link information table-added document storage unit 102b stores the link information table-added document created in step SF3 described later.

  The wireless communication transmitting / receiving unit 103 exchanges data with a base station (not shown) via an antenna ANT under the control of the CPU 100 during data communication, and receives and demodulates voice data received and demodulated via the antenna ANT during a voice call. While outputting to CPU100, the transmission signal obtained by modulating the audio | voice data supplied from CPU100 is amplified by high frequency, and is sent out from antenna ANT.

  The audio signal processing unit 104 includes a speaker SP and a microphone MIC. The audio data supplied from the CPU 100 is D / A converted into an audio signal to generate sound from the speaker SP, or the audio signal supplied from the microphone MIC is converted into audio data. Or A / D-converted and supplied to the CPU 100.

The display unit 11 is configured by, for example, a color liquid crystal panel including a display driver and a backlight. The display driver receives display data from the CPU 100 under the control of the CPU 100 and displays the display data on the display unit 11. On the other hand, the backlight receives power from a power circuit (not shown) under the control of the CPU 100 and irradiates the display unit 106.
The display unit 11 constitutes a link function display unit by displaying not only the document acquired by the mobile phone 10 but also a link teaching described later.

  The operation unit 12 includes various operation keys such as a power button for turning on / off power, an off-hook / on-hook button operated at the start / end of a call, and a character input button also used as a numeric keypad, and generates signals corresponding to these key operations. To the CPU 100.

B. Operation Next, the operation of the above-described embodiment will be described.
(1) Main Routine FIG. 12 is a flowchart for explaining the operation of the main routine of the mobile phone 10 according to the present embodiment. The following processes including the process related to the subroutine are executed by the CPU 100, and some processes are executed by the CPU 100 in response to a user operation.
First, the CPU 100 acquires a plain document in step SA1. The plain document here refers to a document that can be processed electronically obtained by receiving (downloading) news distribution or the like. The plain document may be read from a recording medium (not shown) that can be connected to the mobile phone 10, or may be processed in some way as long as the present invention can be applied. .
FIG. 3A and FIG. 7A each show an example of a plain document. 3A differs from the plain document in FIG. 3A in that there is no table of contents and the plain document in FIG. 7A has a table of contents.
Subsequent to step SA1, the document size of the acquired plain document is determined (step SA2). The document size is determined by, for example, comparing the number of lines of the plain document with the number of lines when the plain document is displayed on the display unit 11 and determining whether the plain document can fit on one screen. .
Subsequently, in step SA3, it is determined whether the acquired plain document is longer than a predetermined length. For example, it is determined by determining whether the acquired plain document has a length that does not fit on one screen or exceeds the length of 30 lines.

If the length is longer than the predetermined length, the process proceeds to step SA4 to analyze the syntax (format) of the acquired plain document, and in step SA5, 1 to n title part candidates to be linked are extracted (n is a natural number).
Title part candidates can be extracted by, for example, extracting the part from the number displayed at the beginning of the document or at the beginning of a line break to the next line break, or analyzing the font usage status in the document. The method of extracting a predetermined font style part with low usage frequency can be performed alone or in combination. This is because the object extracted by these methods is often the title of each article.

Subsequently, in step SA6, it is determined whether or not the extraction of the title part candidate has succeeded.
In the case of NO in the previous step SA3 (when the length is equal to or less than the predetermined length) or in the case of NO in this step SA6 (when the candidate extraction fails), the process proceeds to step SA18, and the user browses in plain text as usual. . That is, the user operates a cursor key provided on the operation unit 12 of the mobile phone 10 to browse the plain text while scrolling down the window of the display unit 11.
On the other hand, if “YES” in the step SA6, that is, if the extraction of the title part candidate is successful, the process proceeds to a step SA7 to determine the number of characters of the title part candidate. This is a process for determining whether or not the number of characters of the approximate title portion candidate is within a predetermined range, and details will be described later in a subroutine.
Subsequently, it is determined whether or not each title part appears only in one place (steps SA8 and SA9). If the obtained plain document appears only in one place, the obtained plain document is a document without a table of contents (step SA10). If two or more locations appear, it is determined that the document has a table of contents (step SA13). Specifically, in the plain document of FIG. 3 (a), each title part appears only at one place, so it is determined that the document has no table of contents. In the plain document of FIG. 7 (a), two title parts appear in the table of contents. It is determined that the document is present.

If it is determined that the document does not have a table of contents, the link information table (1) -0 is created (step SA11), and if it is determined that the document is a table of contents, the link information table (2) -1 is created (step SA14). Each created table is stored in the link information table storage unit 102a.
FIG. 3B shows a specific configuration example of the link information table (1) -0.
As shown in this figure, the link information table (1) -0 is composed of headings of symbols / title portions / link destination positions and main bodies corresponding to these.

The symbol refers to an index uniquely given to each extracted title part, and is assigned as a link key in association with any key of the operation unit 12 by the CPU 100 (see step SB5 described later). Here, the link key refers to a conceptual and functional key composed of hardware (such as a numeric keypad) and software (a predetermined process). As such a link key, from the viewpoint of operability, it is desirable that the ten key “1” and the symbol “1”, the ten key “2” and the symbol “2”, the ten key “3” and the symbol “3” are used. It is good to assign it correspondingly. In the following description, the word “link key” may be used even when the elements constituting the link key such as a numeric keypad and symbols are conscious of the functional aspect.
The title part is a title part extracted from a plain document. Each title portion preferably refers only to a title portion that has been determined to be a title portion through a predetermined process described later (see step SB4 described later).
The link destination position is a position occupied by each extracted title portion in the plain document, and is specified by the CPU 100. This link destination position is also a position to jump to when a predetermined operation is performed during browsing (step SA16) using link display control described later. Therefore, the word “jump destination position” may be used in this specification as meaning the word “link destination position”. Since it is sufficient to jump to the head of each title part, it is not necessary to specify the column position as the link destination position, but of course, this may be specified.
The link information table correlates these symbols / title portions / link destination positions. By associating the symbols 1 to 3 with the numeric keys 1 to 3, it is possible to associate each identified link destination position with each key of the numeric keypad.

  In the case of a document without a table of contents, after the link information table (1) -0 as shown in FIG. 3B is created, the table of contents list in FIG. 3C composed of the link key and the extracted title part. Is created, and this table of contents list is added to the head portion of the plain document as shown in FIG. 3D, and link teaching is performed (step SA12). Since the position information of the title part is changed by adding the table of contents list, the link information table (1) -0 is updated to become the link information table (1) -1 in FIG. By displaying as shown in FIG. 3D, the user is instructed that the numeric keypad and symbol as the link key are associated with the title part of the link destination. Note that the added table of contents list may be popped up as shown in FIG. 4B for emphasis, or one or both of the added table of contents list and jump destination may be underlined. Good (see FIG. 4 (b) etc. and FIG. 8 (b) etc.).

On the other hand, in the case of a document with a table of contents, after a link information table (2) -1 as shown in FIG. 7B is created, a symbol is added at the head of each title in the table of contents as shown in FIG. 7D. (Number) 200 is added and link teaching is performed (step SA15). By being displayed as shown in FIG. 7D, the user is instructed that the numeric keypad and symbol as the link key are associated with the title part of the link destination.
As shown in FIG. 11 (a), when the original document includes a lot of title parts, the numbers 1 to 9 are not sufficient, and as shown in FIG. 11 (b), asterisks “*” and sharp “#” A symbol such as “1” + “0” may be recognized, for example, “10” may be recognized as “1” + “0”. Alternatively, for example, a certain title portion is grouped to reduce the number of assignments, such as assigning a link key “1” to A to C and a link key “2” to E to A. Also good.
As described above, after the predetermined processing of steps SA10 to SA15 is performed according to the presence or absence of the table of contents, the user browses using the link display control in step SA16, and the document is stored according to the user's desire, The main routine document processing is terminated.

(2) Title Part Candidate Character Number Determination Process FIG. 13 is a flowchart showing the operation of the process relating to the title part candidate character number determination in step SA7. This process is based on the outline extracted as the title part candidate, and further extracts the number of characters within a predetermined number of characters.
In the title part candidate character number determination process, the CPU 100 first assigns 1 to i representing the ordinal number of the extracted title part and initializes i = 1 (step SB1).
Subsequently, the number of characters of the i-th title part candidate is determined (step SB2). Here, the number of characters of the first title part candidate is determined, and it is determined whether or not the determined number of characters is within a predetermined number of characters (step SB3). That is, since the title portion is generally characterized by being within a range of an appropriate length as a title, it is too short (for example, 5 characters or less), or conversely, is too long (for example, 25 characters or more). By appropriately omitting things, it is possible to screen out title parts from those that are not.
Therefore, in step SB3, if the number of characters of the title part candidate is within the predetermined number of characters, it is determined that the title part candidate is the title part (step SB4), and if not within the predetermined number of characters. It is determined that the title part candidate is not a title part (step SB6).

If it is determined that it is a title part, first, the position occupied by the title part in the plain document is specified as a jump destination (step SB4-2). For example, as shown in the link information table (1) -0 in FIG. 3B, the “second line head position” is specified. As described above, the column position may be specified. Subsequently, after assigning any key of the operation unit 12 of the mobile phone 10 as a link key to the title portion determined to be the title portion (step SB5), i is incremented by 1 from the state of i = 1. Then, i = 2 is set (step SB7).
On the other hand, if it is determined that it is not the title portion, i is incremented by 1 from i = 1 to i = 2 (step SB7).
Following step SB7, it is determined whether the ordinal number i of the title part is larger than the number n of candidate title parts (step SB8). If NO (if i is n or less), the process returns to step SB2. The processes of SB2 to SB8 are repeated. On the other hand, if YES (i is greater than n), the subroutine relating to the title part candidate character number determination is terminated and the process returns to the main routine.

In the above embodiment, a link key is assigned in step SB5 whenever it is determined in step SB4 that the title portion is determined and the position of the title portion is specified in step SB4-2.
However, pasting a link to something that is immediately visible to the user may result in excessive links.
Therefore, a link may not be pasted for a user at a position that can be seen immediately.
For example, the two titles “A. Push this week” in the menu content part and the information content part of FIG. 14A are linked to each other as shown in FIG. Is close. Therefore, the CPU 100 may determine whether or not to assign a link key based on whether or not to enter one screen between the steps SB4 and SB4-2 or between the steps SB4-2 and SB5. A predetermined number of lines (for example, 10 lines) or a predetermined number of characters (for example, 160 characters) may be used as a criterion for assignment determination.

(3) Browsing Using Link Display Control Hereinafter, the procedure of browsing (step SA16 in FIG. 12) using link display control related to a user operation will be specifically described with reference to the flowchart of FIG.
(3.1) When there is no table of contents list in the original document As described above, when there is no table of contents list in the original document as shown in FIG. 3 (a) or FIG. 4 (a), FIG. The document to which the table of contents list is added (popped up) as shown in 4 (b) is displayed on the display unit 11.
When the user touches this table of contents list, the link keys “1”, “2”, and “3” indicate the titles “1. Push this week”, “2. New strategy of Oyama company” and “ It is recognized that “3. Chairman Koyama, hit the world!” Is linked (step SC1 in FIG. 15).
Subsequently, the user operates a desired link key (step SC2). That is, for example, when browsing an article titled “1. Press this week”, the user selects the link key “1” and presses the center key (soft key label) “jump”.
Then, based on the link information table (1) -1, the CPU 100, as shown in FIG. 5A, the head of the title “1. Press this week” that is the link destination corresponding to the link key “1”. Display control for jumping to is performed (step SC3).
Similarly, if you want to browse articles related to “2. New Oyama company strategy”, use link key “2”. If you want to browse articles related to “3. When the user selects “3” and performs a jump operation, the CPU 100 causes the jump to the link destination corresponding to the link key “2” or “3” as shown in FIG. 5B or 5C. Take control.
When the document browsing is completed by the above procedure, the process is returned to the main routine.
As described above, according to the mobile phone 10 to which the present invention is applied, since it is possible to jump to the target article content at a stretch, the convenience is greatly improved.

In the present invention, in order to further improve convenience, in addition to being able to jump to the article content as described above, it is also possible to return jump from the jumped article content.
Specifically, as described above, by operating the return key as the soft key label from the jump destination as shown in FIG. 5A, FIG. 5B, or FIG. 5C, FIG. a), it is possible to return to the table of contents list as shown in FIG. 6B or 6C. Each time the link key is pressed (the display position) may be toggled.
When the return operation is also possible in this way, the link information table (1) to be created is also input with information related to the “link source position” as in the link information table (1) -2 in FIG. Must be.
In the link information table (1) -2, in all cases, the link source position is the table of contents list position as a whole, but the return position is different for each of the first, second, and third lines. Also good.
In this way, when the return operation is also possible, the procedure related to the return operation is added after step SC3 in FIG.

(3.2) When there is a table of contents list in the original document Even in this case, the browsing procedure is the same as when there is no table of contents list.
Since the original document originally has a table of contents list as shown in FIG. 8A, the displayed document has a symbol (number) added to the head of each title of the table of contents as shown in FIG. 8B. It will be.
When the jump operation is performed by selecting the link key “1”, “2” or “3” (step SC2), the jump is made to the corresponding position as shown in FIG. 9A, FIG. 9B or FIG. 9C. (Step SC3).
When a return key is selected and a return jump operation is performed, a jump is made to a corresponding position as shown in FIG. 10 (a), FIG. 10 (b), or FIG. 10 (c).
Each of FIGS. 10A to 10C shows the case where the information table (2) created in step SA14 is the information table (2) -1 as shown in FIG. 7B. It is shown.
If the table to be created is the information table (2) -2 as shown in FIG. 7C, the first line start position is designated as the link source position (table of contents part), so the return operation is performed. In this case, the process returns to FIG. 10 (a) from any of the cases of FIGS. 9 (a) to 9 (c).
When the document browsing is completed by the above procedure, the process is returned to the main routine.

(4) Creation timing of link information table In the above embodiment, the link information table (1) or (2) is created immediately before step SA16, that is, at the time of browsing. However, the link information table can be created when the user receives mail or when the user transmits mail. This point will be described with reference to FIGS. 16 and 17.
FIG. 16 is a flowchart for showing that a link information table is created when mail is received.
First, the CPU 100 receives a mail at step SD1.
Subsequently, when it is possible to display with a link function in step SD2, that is, when YES is determined in step SA6 in FIG. 12, a document with a link function is displayed in step SD3.
In step SD3, a process corresponding to steps SA7 to SA9 to SA12 or steps SA7 to SA9 to SA15 is performed, so that a link information table (1) or (2) is created and a document with a link function is displayed. Is done.
Thereafter, the user performs browsing using the link display control in the same manner as in step SA16 (step SD4).

On the other hand, FIG. 17 is a flowchart for showing creation of a link information table at the time of mail transmission.
The user first creates a plain mail document in step SE1, and prepares for mail transmission in step SE2.
If display with a link function is enabled in step SE3, that is, if YES is determined in step SA6 in FIG. 12, a document with a link function is displayed in step SE4.
In step SE4, a process corresponding to steps SA7 to SA9 to SA12 or steps SA7 to SA9 to SA15 is performed, so that a link information table (1) or (2) is created and a document with a link function is displayed. Is done.
Subsequently, in response to the user's transmission instruction, the CPU 100 transmits a mail with a link information table in step SE5.

(5) Document Storage FIG. 18 is a flowchart showing a subroutine for document storage processing in step SA17 of FIG.
First, in step SF1, the user determines whether or not to save a document with a link information table, and performs a necessary operation via the operation unit 12.
When the user gives an instruction to save with the link information table (YES in step SF1), the CPU 100 adds an appropriate identifier to the link information table (step SF2). After the document is stored in the document storage unit 102b as a document with a link information table (step SF3), the process is returned to the main routine.
On the other hand, when the user gives an instruction not to attach the link information table (NO in step SF1), the CPU 100 returns the process to the main routine without performing any special process.

(6) Work on Document As described above, a document is stored with or without an identifier added depending on the presence or absence of a link information table. Hereinafter, the processing procedure according to the presence or absence of the identifier will be briefly described with reference to FIG.
First, in step SG1, the CPU 100 acquires a link information table (with / without) document.
Subsequently, by determining the identifier (step SG2), it is determined whether or not the link table is attached to the document (step SG3).
If the link table is not attached, the user performs a desired operation on the document without the link table (step SG6).

Is assigned as a link key, and a link information table is created in which each identified position is associated with each link key. Each link key is associated with the title portion at the jump destination position. The link position is taught based on the link information table when the user operates the link keys. Acquires, has a configuration for controlling the display to jump to the document location of the jump destination.
Therefore, it is possible to comfortably perform browsing using the document link function by using input means such as a numeric keypad originally provided in the mobile phone 10.

In addition to these, the following effects (a) to (j) can also be achieved.
(A) Since the table of contents is created and displayed even when there is no portion corresponding to the table of contents, browsing using the link function can be performed comfortably.
(B) Even if the symbol included in the title part of the original document does not correspond to the key originally provided in the document processing apparatus, the correspondence between the title part and the key can be clearly shown. Can be done comfortably.
(C) Only an appropriate title part can be easily (accurately) extracted.
(D) The link information table creation work (which is a heavy work to some extent) can be performed only when necessary.
(E) The link function can be assigned only to a location where browsing using the document link function is required.
(F) A display with a link function can be automatically prepared without the user being aware of it.
(G) When a mail is received, browsing using a link function becomes possible.
(H) Since a document with a link information table can be sent at the time of mail transmission, the load on the receiving side can be reduced when browsing on the receiving side using the link function.
(I) If a link information table is created once, a link information table that has already been created can be used for the second and subsequent times.
(J) A document with a link table and a document without a link table can be properly used as needed.
