Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic mail apparatus and an electronic mail system which can effectively use limited resources such as a data display section and a storage capacity.

[0002]

2. Description of the Related Art In recent years, mobile phones and personal digital assistants capable of sending and receiving electronic mail have become widespread. In addition, by transferring the e-mail that arrived at a personal computer to a mobile phone or a personal digital assistant, it became possible to read the e-mail that arrived at me even when I was out.

[0003]

However, mobile information terminals such as mobile phones and personal digital assistants often have a smaller number of characters that can be displayed at a time than general personal computers. For this reason, it is difficult to view the entire body of the email, which hinders quick understanding of the main points of the email.

In particular, when an electronic mail sent to a personal computer is being transferred to a mobile information terminal, the sender may send a long sentence in order not to consider reception by the mobile information terminal. In this case, the above problem becomes more serious.

For example, Japanese Unexamined Patent Publication No. 2000-148338 discloses a data display device that can effectively utilize a small display area. However, this device is intended for data having a hierarchical structure created in advance, and is not intended for general electronic mail. Further, conventionally, there is no one having a means for extracting an important part from a general electronic mail.

Further, since the storage capacity for storing and storing the contents of the electronic mail is limited, the unnecessary electronic mail is deleted, but the method is to delete the oldest ones in order. Method and, for example, JP-A-9-238
There is a method disclosed in Japanese Laid-Open Patent Application No. 373, "Selective Call Receiver and Message Saving / Deletion Method" and the like. The outline of this method is as follows.

1. The user specifies lock or importance by looking at the content of the email. 2. This information is stored with the email. 3. When a new electronic mail is received and there is no storage area, the electronic mail having the lowest importance is deleted and the new electronic mail is stored together with the lock designation or the importance designation.

As described above, conventionally, in order to save necessary e-mails, various measures have been taken such as deleting the e-mails in order of importance. However, in the past, it was not possible to use the storage capacity efficiently because it was only decided whether to delete or to save each e-mail.

This problem becomes very noticeable when it becomes possible to send a long sentence by electronic mail. In particular, when the e-mail sent to the personal computer is being transferred to the mobile information terminal, the sender may send a very long sentence in order to avoid receiving the e-mail at the mobile information terminal. If this email contains some important information, if you want to erase this email you have to remember the important information in some other way, and if you want to save this email There is a problem that a large amount of storage capacity is consumed.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to specific examples. << Specific Example 1 >><Configuration> FIG. 1 is a configuration diagram showing a specific example 1 of the electronic mail apparatus of the present invention. The apparatus shown in the figure has a receiving unit 101, a processing unit 102, a transmitting unit 103, an electronic mail storage unit 104, an input unit 105, a display unit 106, an electronic mail storage unit 107, a document structure analysis unit 108, an important sentence extraction unit 109, and an important sentence. Partial data creation unit 110, display mode changeover switch 111
Consists of.

The receiving unit 101 is a functional unit that receives electronic mail. The processing unit 102 is a functional unit that manages various processes related to electronic mail, and performs, for example, a process of sending an instructed electronic mail to the transmitting unit 103 according to a command for transmitting the electronic mail input from the input unit 105. It is a thing. Further, the processing unit 102 has a function of receiving a request from the user to switch the display method by the display mode selection switch 111 and performing a process of switching between displaying only important sentences and displaying all sentences.

The transmitting unit 103 is a functional unit that receives an instruction from the processing unit 102 and transmits an electronic mail. The e-mail storage unit 104 is a functional unit that stores e-mails that have arrived and e-mails that have not been written, along with the attribute information of the e-mails. Further, the e-mail storage unit 104 stores information on important parts of the e-mail (important part data 15 described later).
It has the function of storing 6). The input unit 105 is a functional unit that inputs texts and commands such as transmission of electronic mail. The display unit 106 is the input unit 105.
It is a functional unit that displays a sentence input in step S1, an electronic mail received by the receiving unit 101, and the like, and is specifically a liquid crystal display or the like in a mobile phone.

The electronic mail storage unit 107 is a storage unit for temporarily storing the contents of the received electronic mail. The document structure analysis unit 108 is a functional unit that divides the body of the electronic mail into a plurality of blocks including sentences, that is, divides the body into paragraphs, and further divides the paragraphs into sentences. The important portion data creating unit 110 is a functional unit that creates important portion data indicating the position where the important sentence extracted by the important sentence extracting unit 109 exists.

The display mode switching switch 111 is a switch for switching between a summary display mode in which only important sentences are displayed and a full-text display mode in which all sentences are displayed when displaying the contents of the received electronic mail.

<Operation> Next, the operation of the first embodiment will be described. This device operates as an e-mail device for reading and writing e-mail as a whole. Since the only difference from the general electronic mail device is the operation at the time of receiving the electronic mail and the operation at the time of displaying the electronic mail, these operations will be described.

1. Operation when Receiving E-mail FIG. 2 is a flowchart showing the operation when receiving an e-mail in the first specific example. When the e-mail arrives, the receiving unit 101 receives the e-mail and transfers it to the e-mail storage unit 107 (step S101). Next, the document structure analysis unit 108 divides the body of the electronic mail stored in the electronic mail storage unit 107 into paragraphs, and further divides each paragraph into sentences (step S102). As a method of dividing into paragraphs, for example, when there is one blank line or when there are a plurality of blank lines in succession, this place is used as a break of the paragraph. As a method of dividing a sentence, for example, when there are characters such as “.”, “.”, “?” And “!” (Full-width characters and half-width characters), it is determined that the sentence ends.

The important sentence extraction unit 109 is the document structure analysis unit 1.
Important sentences are extracted from the sentences divided by 08 (step S103). Here, the important sentence is a sentence for summarizing the text, and various methods can be applied as a method of extracting such an important sentence. For example, JP-A-11-27
Any method may be used, such as a method in which an important expression is described in advance as disclosed in Japanese Patent No. 2686 and an important sentence is extracted based on this table.

FIG. 3 is an example of a data structure (document analysis data 150) showing the processing results of steps S102 and S103. FIG. 4 is an explanatory diagram showing an example of an electronic mail.

FIG. 3 shows a case where the electronic mail shown in FIG. 4 is processed. The document analysis data 150 created by the document structure analysis unit 108 includes paragraph number 151, sentence number 152, sentence start position 153, Sentence end position 154,
The important flag 155 includes the following meanings.

The paragraph number 151 is a serial number given to each paragraph in order from the beginning of the electronic mail text. The sentence number 152 is a serial number attached to each sentence in order from the beginning of the email body. The sentence start position 153 is
Indicates the starting position of the corresponding sentence in the email body. The sentence end position 154 indicates the end position of the corresponding sentence in the email body. The important flag 155 indicates that the important sentence extracting unit 1
"1" is assigned to the sentence extracted as the important sentence by 09, and "0" is substituted otherwise. Although there is a content column in FIG. 3, this is provided for the purpose of explanation and is not necessary for the actual data structure. Further, the sentence start position 153 and the sentence end position 154 respectively indicate the number of bytes in the text, but when the JIS code is used for the kanji code, it includes a 3-byte special code for shift-in and shift-out. Therefore, the start position and end position of the apparent number of characters in the content do not necessarily match. For example, if the content of sentence 1 is "Endo @ AAAAA part.", "Shift-in + 12 full-width characters + shift-out + line feed" = 3 + 2
4 + 3 + 1 = 31, and the end position of the first sentence is the 31st byte.

The important part data creation unit 110 takes a continuous important sentence in the document analysis data 150 as one section, and extracts the start position and the end position of the sentence.
Data indicating the range in which an important sentence exists (important part data 1
56) is created (step S104).

FIG. 5 is an explanatory diagram showing an example of the data structure of the important part data 156. This is an example of the case where the important part data 156 is created from the document analysis data shown in FIG. In the figure, the important part data 156 is composed of a partition number 157, a partition start position 158, and a partition end position 159, and their meanings are as follows. The section number 157 is a serial number sequentially assigned to each section from the beginning of the email body. The partition start position 158 indicates the start position of the corresponding partition. The partition end position 159 is
Indicates the end position of the corresponding section.

Returning to FIG. 2 again, the processing section 102 causes the important part data creating section 110 to create the important part data 156.
The information of the received electronic mail stored in the electronic mail storage unit 107 is stored in the electronic mail storage unit 104 (step S105), and the process ends.

2. Operation During Display of E-mail FIG. 6 is a flowchart showing the operation during display of the e-mail and the pressing of the display mode changeover switch 111 during the display of the e-mail in the first specific example. Figure 7
It is explanatory drawing of the switching operation between a summary display mode and a full-text display mode.

In FIG. 6, when the display mode changeover switch 111 is pressed during the display of the electronic mail, the process starts from the figure. When the electronic mail is displayed, the display mode is set to the summary display mode (step S110), and when the display mode switching switch 111 is pressed, the display mode is switched (step S111). As shown in FIG. 7, this switching causes the summary display mode and the full-text display mode to be switched each time the display mode changeover switch 111 is pressed. Then, the display mode is checked (step S112), and if the display mode is the full text mode, the full text is displayed as usual (step S113), and the process ends.

On the other hand, when the display mode is not the full-text mode, that is, in the summary display mode, first, the important part data 156 created at the time of reception and stored in the e-mail storage unit 104 is taken out (step S114). Next, from the first section of the important part data 156 in order (step S1
15), the values of the section start position 158 and the section end position 159 of the relevant section are taken out and the contents of the range are displayed (step S116). This operation is sequentially repeated until the last section (step S117), and the process is completed.

FIG. 8 is an explanatory diagram of the summary display and the full text display. As shown in the figure, the user selects and displays a summary display consisting of only important sentences and a full text display in which the entire electronic mail is displayed.

<Effect> As described above, according to the first specific example,
Since the summary display and the full text display are switched and displayed, the following effects are obtained. ● With the summary display function that displays only important sentences, even if the display area is small, you can get an overview with a small number of screen scrolls. For example, when the body of the electronic mail shown in FIG. 4 is read on a screen of 10 double-byte characters in the horizontal direction and 8 lines in the vertical direction, the whole text is for 6 screens, while the summary result is for 2 screens. In addition, in the case of this e-mail, one of the important matters is that the processing deadline is 12/20 (Wednesday), but it can be seen that the conventional display (full text display) does not reach the 5th screen. In contrast, the summary display can be seen on the second screen.

Since it is possible to know the outline to some extent only with the first one screen, when searching for the target e-mail from many e-mails that have already been received, it is possible to search for it with fewer operations because scroll operation is not necessary. The operability is improved. For example, if you display it from the beginning of the whole sentence, the screen may be filled with standard greetings and seasonal greetings, and the information that distinguishes the important contents may not be displayed on the screen. By doing so, standard greetings and seasonal greetings are omitted, and it is easy to distinguish the contents.

It is particularly easy to operate if the summary of electronic mails received before and after can be displayed one after another by pressing a specific button while displaying the summary.

After searching for the target e-mail while looking at the summary display, the user can press the button to switch to full-text display and read the e-mail as usual.

Since the important sentence extraction process only needs to be performed once upon reception, switching is smoother than when the important sentence is extracted each time it is displayed, so that it can be used comfortably.

As the information to be stored in addition to the original information of the received electronic mail, only the range in which the important sentence exists is stored, so the amount of information is small. For example, as compared with specific examples 2 and 3 described later. The storage capacity can be effectively used.

<< Specific Example 2 >> In the specific example 2, a predetermined identification symbol ([+]) is displayed in a range that is not important at the time of displaying the summary, and the contents are hidden at this position for displaying the summary. Indicates that there is an item, and if the user specifies that part, the contents of that part will be displayed, and if a part of the unimportant range displayed on the contrary is specified, the contents of that range will be displayed.
Instead, an identification symbol is displayed. FIG. 9 is an explanatory diagram of the display switching operation of the second specific example.

<Structure> FIG. 10 is a block diagram of the second specific example. The apparatus shown in the figure includes a receiving unit 101, a processing unit 102a, a transmitting unit 103, an electronic mail storage unit 104, an input unit 105, a display unit 106, an electronic mail storage unit 107, a document structure analyzing unit 108, an important sentence extracting unit 109, and an important sentence. Partial data creation part 1
10, a display mode changeover switch 111, a range data creation unit 201, and a display state changeover switch 202.

In the figure, the receiving section 101 to the display mode changeover switch 111 are the same as those in the concrete example 1 shown in FIG. 1, so the corresponding parts are designated by the same reference numerals and the description thereof is omitted. The range data creation unit 201 is a functional unit that creates range data that is separated into a range in which the important sentence exists and a range in which the important sentence does not exist based on the important sentence extracted by the important sentence extraction unit 109. The display state changeover switch 202 is a switch for changing over the display of a range in which no important sentence exists.

Then, when the processing unit 102a receives a non-display request from the user for a range including only unimportant sentences in the body of the electronic mail, instead of displaying the range, a predetermined identification symbol ([+ ]) Is displayed, and when the identification symbol is displayed while the identification symbol is displayed, the content of the range corresponding to the position of the identification symbol is displayed based on the division result in the range data creation unit 201. It is configured to display. Further, the processing unit 102a is configured to highlight important sentences in bold letters as shown in FIG.

<Operation> Next, the operation of the second specific example will be described. This device operates as an e-mail device for reading and writing e-mail as a whole. The difference from the general electronic mail device is only the operation when receiving an electronic mail and the operation when displaying an electronic mail. Therefore, these operations will be described, and the operation when the display state changeover switch 202 is pressed. Will be described.

1. Operation when Receiving E-mail FIG. 11 is a flowchart showing the operation of the second specific example. In FIG. 11, steps (steps) that are the same as those in the specific example 1 are given the same step numbers as those in the specific example 1.

Since steps S101 to S103 are the same as those in the concrete example 1, the description thereof is omitted here. After step S103, the range data creation unit 201
Creates a range where the important sentence exists and a range where the important sentence does not exist (range data 203) in the document analysis data 150 (step S201).

FIG. 12 is an explanatory diagram showing an example of the data structure of the range data 203. This is an example when the range data 203 is created from the document analysis data shown in FIG. As illustrated, the range data 203 includes a range number 204, a range start position 205, a range end position 206, and a range important flag 207, and their meanings are as follows. The range number 204 is a serial number added to each range in order from the beginning of the email body. The range start position 205 indicates the start position of the corresponding range. The range end position 206 indicates the end position of the corresponding range.
The range important flag 207 is set to 1 when the range is composed of important sentences, and is set to 0 otherwise.

Returning to FIG. 11 again, the processing unit 102a stores the range data 203 created by the range data creating unit 201 and the information of the received electronic mail stored in the electronic mail storage unit 107 in the electronic mail storage unit 104. (Step S2
02), the processing is ended.

2. Operation during Display of E-mail FIG. 13 is a flowchart showing the operation during display of an e-mail and the pressing of the display mode changeover switch 111 during the display of an e-mail in the specific example 2. 14
FIG. 7 is an explanatory diagram of a mode switching operation between a summary display mode and a full text display mode.

When the electronic mail is displayed, the display mode is set to the summary display mode (step S210). That is, since only the important sentence is displayed, it is in a state of being highlighted in bold type. When the display mode changeover switch 111 is pressed during the display of the electronic mail, the process starts from the figure.

When the display mode changeover switch 111 is pressed, the processing section 102a first confirms the current display state (step S211). The current display status is
Refers to the whole display, summary display, or intermediate state, which is the display state and range data 20 for each range at that time.
From 3 is determined as follows. When all the ranges are displayed, the important (range important flag 207
If only the range is displayed, the display is a summary display; otherwise, the display is in an intermediate state.

Next, the display mode is switched (step S212). As shown in FIG. 14, this switching is switched to the full-text display mode in the summary display mode, and to the summary display mode in the full-text display mode and the intermediate state. Then, the range data 203 is sequentially extracted from the first range (step S
213), it is checked whether the applicable range is an important range (step S214), and if important, the values of the range start position 205 and the range end position 206 are extracted, and the contents of the range are displayed in bold type (step S215).

On the other hand, when it is not in the important range, it is checked whether the display mode is the summary display mode (step S21).
6) In the summary display mode, the [+] sign is displayed (step S217), and if different, the values of the range start position 205 and the range end position 206 are extracted and the contents of the range are displayed (step S218). This operation is sequentially repeated up to the last range (step S219), and the process ends.

3. Operation when the display state changeover switch 202 is pressed FIG. 15 is a flowchart showing an operation when the display state changeover switch 202 is pressed during the email display in the second specific example. When the display state changeover switch 202 is pressed, the processing unit 102a first acquires the range number 204 corresponding to the position of the cursor at that time (step S230). Next, it is checked whether or not this range is an important range (range important flag 207 is set to 1) (step S231), and if important, a warning sound is given to inform the user that the display cannot be changed (step S231). S232). On the other hand, if not important, [+]
Check whether the symbol is displayed (step S23
3) When the [+] sign is displayed, the values of the range start position 205 and the range end position 206 of the corresponding range are extracted instead of the sign and the contents of the range are displayed (step S).
234). On the other hand, if not, the [+] symbol is displayed instead of the content display of the corresponding range (step S235).

<Effect> As described above, according to the second specific example, when a range in which an important sentence exists is obtained, and a non-display request for a range including only unimportant sentences is received, the range is displayed instead. When the identification symbol is specified while the identification symbol is displayed, the contents of the range corresponding to the position of the identification symbol are displayed, and the important sentence is highlighted. Since it is displayed, it has the following effects.

Since the important part is displayed in bold type, the important part is easy to understand. ● Since non-important parts can be hidden temporarily, a small display area can be effectively used. ● When there is a hidden sentence, the [+] symbol is displayed.
You can know the existence of hidden sentences. ● Directly specifying the [+] sign switches to display the hidden sentence in that part, so the operation is direct and easy to understand. Similarly, when hiding a sentence, it is easy to understand because the sentence can be directly specified.

<< Specific Example 3 >> In the specific example 3, display and non-display can be switched in units of sentences by the following method. ● If there is a hidden sentence in a paragraph, [+] at the beginning of the paragraph
The symbol (second identification symbol) is displayed, and when all the sentences in the paragraph are displayed, the [] symbol (first identification symbol) is displayed. ● If the user specifies the [+] sign, the entire paragraph will be displayed. ● If the user specifies the [] symbol, the paragraph is switched to display only important sentences. ● If the user specifies a sentence other than the important sentence, that sentence is hidden.

<Structure> FIG. 16 is a block diagram of the third embodiment. The apparatus shown in the figure includes a receiving unit 101, a processing unit 102b, a transmitting unit 103, an electronic mail storage unit 104, an input unit 105, a display unit 106, an electronic mail storage unit 107, a document structure analysis unit 108, an important sentence extraction unit 109, and a display. The mode changeover switch 111, the range data creation unit 201, and the sentence display state storage unit 301 are included.

In the figure, the receiving unit 101 to the display mode changeover switch 111 and the range data creating unit 201 are the same as those in the concrete example 1 or the concrete example 2, and therefore the corresponding parts are designated by the same reference numerals and the explanation thereof is omitted. To do. The sentence display state storage unit 301 is a functional unit that stores the current display state of each sentence. Further, the processing unit 102b does not display the [] symbol (first identification symbol) in the paragraph when all the sentences in the paragraph are displayed for each paragraph divided by the document structure analysis unit 108. When there is a sentence, the [+] sign (second identification symbol) is displayed at the beginning of the paragraph, and when a request to hide any sentence in the email body is received, the arbitrary sentence is hidden. If the [] symbol is specified while the [] symbol is displayed, only the important sentence in the relevant paragraph is displayed based on the result extracted by the important sentence extraction unit 109. On the other hand, when the [+] symbol is displayed and the [+] symbol is specified, the function has the function of displaying all the sentences in the corresponding paragraph.

<Operation> Next, the operation of the third specific example will be described. This device operates as an e-mail device for reading and writing e-mail as a whole. The difference from the general electronic mail device is only the operation when receiving an electronic mail and the operation when displaying an electronic mail. Therefore, these operations will be described, and the operation when the display state changeover switch 202 is pressed. Will be described. FIG. 17 is an explanatory diagram of display contents by display switching of the third specific example.

1. Operation when Receiving E-mail FIG. 18 is a flowchart showing the operation of the third specific example. In FIG. 18, the same parts (steps) as those of the concrete example 1 are given the same step numbers as those of the concrete example 1.

Since steps S101 to S103 are the same as those in the first specific example, the description thereof is omitted here. After step S103, the processing unit 102b stores the document analysis data 150 created by the document structure analysis unit 108 and the important sentence extraction unit 109 and the information of the received electronic mail stored in the electronic mail storage unit 107 in the electronic mail storage unit 104.
(Step S301), and ends.

2. Operation During Display of E-mail FIG. 19 is a flowchart showing an operation during display of an e-mail and a press of the display mode changeover switch 111 during the e-mail display according to the third specific example. Figure 20
FIG. 20 is a flowchart showing details in the case of updating the display of the paragraph in step S315 in FIG. FIG. 21 shows
It is explanatory drawing of a display mode switching operation.

When displaying the electronic mail, the display mode is set to the summary display mode (step S310). When the display mode changeover switch 111 is pressed, the processing unit 102
b first confirms the current display state (step S3).
11). The current display state indicates one of the whole display, the summary display, and the intermediate state, which is the sentence display state storage unit 30.
It is determined as follows from the display state at that time and the document analysis data 150 for each sentence stored in 1. When all the sentences are displayed, the whole display is displayed. When only the important sentence (the sentence in which the important flag 155 is set to 1) is displayed, the summary display is displayed. In other cases, the intermediate state is displayed. .

Next, the display mode is switched (step S
312). As shown in FIG. 21, this switching is switched to the full-text display mode in the summary display mode, and to the summary display mode in the full-text display mode and the intermediate state. Then, display information is set in the sentence display state storage unit 301 based on the display mode (step S313). Specifically, in the full-text display mode, all the sentences are set to be displayed, in the summary display mode, only the important sentences are set to be displayed, and the others are set to be invisible.

Finally, the first paragraph of the document analysis data 150 is taken out in order (step S314), and the display of the relevant paragraph is updated (step S315). The operation of updating the display of paragraphs will be described later. This operation is repeated until the last paragraph (step S316), and the process ends.

2. Operation when the display state changeover switch 202 is pressed FIG. 22 is a flowchart showing the operation when the display state changeover switch 202 is pressed during the email display in the third specific example. When the display state changeover switch 202 is pressed, the processing unit 102b first checks whether the cursor at that time is on the sentence or the [+] or [] symbol (step S340). When the cursor is on the sentence, the sentence is set to non-display in the sentence display state storage unit 301 (step S34).
1). On the other hand, if it is on the [+] or [] symbol, the paragraph number indicated by the symbol is acquired (step S342), and it is checked whether this symbol is [+] or []. (Step S343). When the symbol is [+], the sentence display state storage unit 301 is set to display all the sentences in the paragraph indicated by the paragraph number (S).
344). On the other hand, when the symbol is [], the important sentence is set to be displayed and the other sentence is not displayed in the sentence display state storage unit 301 for each sentence in the paragraph indicated by the paragraph number (S34).
5). Whether or not it is an important sentence is determined by referring to the important flag 155 of the document analysis data 150. Finally, the processing unit 1
02b updates the display of the paragraph according to the setting contents of the sentence display state storage unit 301 (step S346), and ends.

Finally, the operation for updating the display of the specified paragraph will be described with reference to the above-mentioned flowchart of FIG. The processing unit 102b firstly, the sentence display state storage unit 3
The display information of the specified paragraph is acquired from 01 (step S32
0), it is checked whether all the sentences in the designated paragraph are set to be hidden (step S321). If all the sentences in the designated paragraph are set to be hidden, the [+] symbol is displayed (S322) and the process ends. At this time, do not insert a line break after [+].

On the other hand, if at least one sentence is set to be displayed in the designated paragraph, it is checked whether all the sentences in the designated paragraph are set to be displayed (step S32).
3). If all the sentences in the designated paragraph are set to be displayed, the [] symbol is displayed (step S324), and if not, the [+] symbol is displayed (step S32).
5).

Next, the first sentence in the designated paragraph is sequentially extracted (step S326), and it is checked whether the sentence is set to be displayed or hidden in the sentence display state storage unit 301 (step S326). S327).
If it is set to be hidden, the process proceeds to step S331 without displaying the sentence, and if it is set to be displayed,
It is checked whether the sentence is an important sentence (S328: refer to the important flag 155 of the document analysis data 150). If the sentence is an important sentence, the sentence is displayed in bold type (step S329), otherwise the sentence is normally displayed. Yes (step S330).
This operation is repeated in order until the last sentence in the designated paragraph (step S331), and the process ends.

<Effect> As described above, according to the specific example 3, the [] symbol is displayed when all the sentences in the paragraph are displayed, and the [+] symbol is displayed when there are hidden sentences in the paragraph. ] Symbol is displayed at the beginning of a paragraph, and if a request to hide any sentence in the email body is received, this sentence is hidden and the [] symbol is displayed. When a symbol is specified, only the important sentence in the corresponding paragraph is displayed based on the result extracted by the important sentence extraction unit 109, while this symbol is displayed while the "+" symbol is displayed. When specified, all sentences in the corresponding paragraph are displayed, and important sentences are highlighted, so that the following effects are obtained.

Since the important parts are displayed in bold type, the important parts are easy to understand. ● Important sentences can also be hidden. ● Since each sentence can be temporarily hidden, a small display area can be used effectively. ● Display and non-display can be switched for each sentence, so detailed operations are possible. ● When there is a hidden sentence, the [+] sign is displayed, but
Since each paragraph is displayed, a small display area can be effectively used. In addition, it is easy to grasp the entire configuration.

<Specific Example 4> In the specific example 4, the important sentence extraction process is executed by the electronic mail transfer server, and the processing result is added to the electronic mail as important partial data and transferred, whereby the processing load on the terminal is increased. This is to reduce the above.

<Structure> FIG. 23 is a block diagram of the fourth specific example. The system shown in the figure is an important part data addition server 40.
1 and an important part data interpretation terminal 402. The important portion data addition server 401 is a server that intensively performs important sentence extraction processing instead of the terminal. The important portion data interpretation terminal 402 is a terminal as an electronic mail device capable of interpreting the processing result of the important portion data addition server 401.

Further, the important portion data addition server 401 is realized by the following constituent elements. That is, the email storage unit 1
07, the document structure analysis unit 108, the important sentence extraction unit 109, the important portion data creation unit 110, the server reception unit 403, the important portion data addition unit 404, and the server transmission unit 405.
Here, since the electronic mail storage unit 107 to the important part data creation unit 110 have the same configurations as those shown in the concrete examples 1 to 3, the corresponding parts are designated by the same reference numerals and the description thereof will be omitted.

The server receiving unit 403 is a functional unit that receives an electronic mail in the important portion data addition server 401. The important part data adding unit 404 is a functional unit that adds the created important part data to the received e-mail and creates a transfer e-mail. The server transmission unit 405 is a functional unit that transmits an electronic mail in the important portion data addition server 401.

The important part data interpretation terminal 402 is realized by the following components. That is, the reception unit 101, the processing unit 102c, the transmission unit 103, the electronic mail storage unit 104, the input unit 105, the display unit 106, the display mode changeover switch 111, and the important portion data interpretation unit 406. Here, the receiving unit 101 to the display mode changeover switch 111
Is the same as the configuration shown in the concrete examples 1 to 3, the corresponding parts are designated by the same reference numerals and the description thereof is omitted. The important portion data interpretation unit 406 is a functional unit that extracts the important portion data added to the received electronic mail. The processing unit 102c is a functional unit that performs the same operation as the processing unit 102 in the first specific example based on the processing result of the important portion data interpretation unit 406.

<Operation> Next, the operation of Example 4 will be described. Since the operation when displaying an electronic mail is the same as that of the first specific example, the description thereof will be omitted, and the operation of the important part data addition server 401 and the operation when the important part data interpretation terminal 402 receives an e-mail will be described. To do.

1. Operation of Important Partial Data Addition Server 401 FIG. 24 is a flowchart showing the operation of the important part data addition server 401 in the fourth specific example. When the electronic mail arrives, the server receiving unit 403 receives the electronic mail and delivers it to the electronic mail storage unit 107 (step S401).
Next, the process proceeds to step S102, but since steps S102 to S104 are the same as in the first specific example, description thereof will be omitted.

When the creation of the important part data in step S104 is completed, the process proceeds to step S402, and the processing unit (not shown) in the important part data addition server 401 creates the important part data 15 created by the important part data creating unit 110.
6, a new field is created, added to the header of the electronic mail stored in the electronic mail storage unit 107, and sent to the server transmission unit 405 (step S402).

FIG. 25 shows an example of a field created from the important part data 156 of FIG. 5 shown in the concrete example 1. As shown in the figure, the position information in the body of the important sentence is added to the header of the e-mail as a result of the extraction process of the important sentence in the important portion data addition server 401.

Next, when the server transmission unit 405 receives the electronic mail in which the field representing the important portion data 156 is added to the header portion, the server transmission unit 405 transmits the electronic mail based on the information of the header (step S403).

2. Operation when Important Partial Data Interpretation Terminal 402 Receives E-mail FIG.
It is a flowchart which shows operation | movement of 02. When the e-mail arrives, the receiving unit 101 receives the e-mail and delivers it to the processing unit 102c (step S410). The important portion data interpretation unit 406 creates important portion data 156 by interpreting the field added by the important portion data addition server 401 from this e-mail (step S41).
1). Finally, the processing unit 102c stores the important part data 156 created by the important part data interpretation unit 406 and the information of the received e-mail in the e-mail storage unit 104 (step S412), and ends the process.

<Effect> As described above, according to the fourth specific example, the important sentence is extracted on the server side, so that the following effects are obtained. ● Since the server extracts important sentences, the processing load on the terminal is small. ● Since the server only adds the processing result to the header and does not change the text, it can be used as before even if the transferred e-mail is received by a general terminal.

<Specific Example 5> In Specific Example 5, the electronic mail transfer server analyzes the document structure, shapes the text based on the analysis result, and executes the important sentence extraction process to obtain the process result as important sentence data. As a result, the processing load on the terminal is reduced by adding and transferring the e-mail.

<Structure> FIG. 27 is a structural diagram of the fifth specific example. The apparatus in the figure is roughly divided into an important sentence data addition server 501 and an important sentence data interpretation terminal 502. The important sentence data addition server 501 is a server that intensively performs the important sentence extraction process instead of the terminal. The important sentence data interpretation terminal 502 is a terminal as an electronic mail device capable of interpreting the processing result of the important sentence data addition server 501.

Furthermore, the important sentence data addition server 501
It is realized by the following components. That is, the email storage unit 1
07, document structure analysis unit 108, important sentence extraction unit 109, server reception unit 403, server transmission unit 405, text formatting unit 5
03, an important sentence data creating unit 504, and an important sentence data adding unit 505. Here, the electronic mail storage unit 107 to the important sentence extraction unit 109 have the same configurations as those shown in the concrete examples 1 to 3, and the server reception unit 403 and the server transmission unit 4 are also included.
Since 05 is the same as the configuration shown in the specific example 4, the same reference numerals are given to the corresponding portions and the description thereof will be omitted.

The text formatting unit 503 is a functional unit that performs formatting based on the result of document structure analysis (document analysis data 150) so that a blank line is inserted when the paragraph changes in the one-sentence one-line format. The important sentence data creation unit 504 is a functional unit that creates important sentence data from the sentence number of the important sentence. The important sentence data adding unit 505 is a functional unit that adds the important sentence data created by the important sentence data creating unit 504 to the electronic mail.

The important sentence data interpretation terminal 502 is realized by the following components. That is, the receiving unit 101, the processing unit 102d, the transmitting unit 103, the electronic mail storage unit 104,
An input unit 105, a display unit 106, a display mode changeover switch 111, an important sentence data interpretation unit 506, and a document analysis data construction unit 507. Here, since the receiving unit 101 to the display mode changeover switch 111 have the same configurations as those shown in the concrete examples 1 to 3, the description thereof is omitted here.

The important sentence data interpretation unit 506 is a functional unit that interprets the important sentence data and obtains the sentence number of the important sentence. The document analysis data construction unit 507 selects the document analysis data 15 from the format in which a blank line is inserted when the paragraph changes in the one-sentence one-line format.
This is a functional unit that constructs 0. Further, the processing unit 102d
This is a functional unit that performs the same processing as the processing unit 102b in the third specific example based on the processing results of the important sentence data interpretation unit 506 and the document analysis data construction unit 507.

<Operation> Next, the operation of the fifth specific example will be described.
Since the operation when displaying an e-mail is the same as that of the third specific example, the description thereof is omitted, and the operation of the important sentence data addition server 501,
The operation when the important sentence data interpretation terminal 502 receives an e-mail will be described.

1. Operation of Important Sentence Data Adding Server 501 FIG.
It is a flow chart which shows operation of 01. When the e-mail arrives, the server receiving unit 403 receives the e-mail and delivers it to the e-mail storage unit 107 (step S501). Next, the process proceeds to step S102, but since steps S102 to S104 are the same as in the first specific example, the description thereof will be omitted. When the important sentence data creation is completed in step S104, the process proceeds to step S502, the processing unit (not shown) in the important sentence data addition server 501 creates a new field from the important sentence data created by the important sentence data creating unit 504, and Is added to the header of the electronic mail in which the text is shaped by the text shaping unit 503 and sent to the server transmission unit 405 (step S502).

FIG. 29 is an explanatory diagram showing an example of fields created from important sentence data. FIG. 30 is an explanatory diagram showing a result of shaping the electronic mail in FIG. 4 by the text shaping unit 503. As shown in FIG. 29, the sentence number in the body of the important sentence is added to the header of the electronic mail as a result of the important sentence extraction processing in the important sentence data addition server 501.
The sentence numbers are assigned such that the first sentence in the body is 1, the second sentence is 2, and so on. Further, as shown in FIG. 30, it can be seen that the line feed codes in the middle of the fifth sentence and the twelfth sentence are removed, and the sentence is in one sentence one line format.

Returning to FIG. 28, when the server transmission unit 405 receives the electronic mail in which the field indicating the important sentence data is added to the header portion, the server transmission unit 405 transmits the electronic mail based on the information of the header (step S503).

2. Operation when Important Sentence Data Interpretation Terminal 502 Receives E-mail FIG.
It is a flowchart which shows operation | movement of 2. When the email arrives, the receiving unit 101 receives the email and the processing unit 10 receives the email.
2d (step S510). The document analysis data constructing unit 507 constructs the document analysis data 150 by utilizing the fact that the body of the received e-mail is in a one-sentence one-line format with a blank line inserted when the paragraph changes (step S511). Further, the important sentence data interpretation unit 506 acquires the sentence number of the important sentence by interpreting the field added by the important sentence data addition server 501, and sets the important flag 155 of the document analysis data 150 (step S).
512). Finally, the processing unit 102d stores the information of the document analysis data 150 having the important flag 155 set by the important sentence data interpretation unit 506 and the received electronic mail in the electronic mail storage unit 1
04 (step S513), and the process ends.

<Effect> As described above, according to Example 5,
Since the server side processes the important sentence extraction process, the text is shaped, and the terminal side uses the shaping result to switch the display, the following effects are obtained.

● Since the server performs the important sentence extraction process, the processing load on the terminal is small. ● Since the server adds important sentence data to the header, it can be used in the same way as before even if the transferred e-mail is received by a general terminal. ● The server formats one sentence and one line so that a blank line is inserted when the paragraph changes, but this is easier to read in the case of a small display area.

<Specific Example 6> In the specific example 6, in the specific example 1, if the user determines that it is sufficient to save only the content displayed in the summary display, the content not displayed in the summary display can be deleted. It was done like this.
