The calculated distance information is evaluated and stored in the evaluation history storage unit 114.

  When the user of the mobile terminal device 110 displays a mail list, the mail display unit 115 refers to the distance information calculation unit 113 and the evaluation history storage unit 114 and presents the most effective mail at the current location.

  Note that FIG. 1 is limited to the mail reception process for the sake of clarity, but in an ordinary mail server and portable information terminal, various electronic mail control processes such as a mail transmission process and a deletion process. Needless to say, it is done. The above is the description of the configuration example of the system in the embodiment of the present invention shown in FIG.

  Next, with reference to FIG. 2, the hardware configuration of various apparatuses according to the embodiment of the present invention will be described. FIG. 2 is a diagram illustrating a hardware configuration of various apparatuses according to the embodiment of the present invention.

  The CPU 201 comprehensively controls devices and controllers described later connected to the system bus 204. In the ROM 203 or the external memory 211, a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as OS), which is a control program of the CPU 201, various processes described later in the mail receiving server 100 and the portable terminal device 110 are stored. Various programs, data, and the like necessary for executing are stored. The RAM 202 functions as a main memory, work area, and the like for the CPU 201.

  The CPU 201 implements various processes to be described later by loading a program or the like necessary for executing the process into the RAM 202 and executing the program. An input controller (input C) 205 controls input from the input device 209.

  The input device 209 is configured by, for example, a mechanical keyboard, a software keyboard, a touch panel, or the like. A video controller (VC) 206 controls display on the display device 210. The display device 210 is configured by a liquid crystal display, for example.

  The memory controller (MC) 207 is stored in a hard disk (HD), solid state disk (SSD), or PCMCIA card slot for storing boot programs, browser software, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a flash memory connected via an adapter.

  A communication I / F controller (communication I / FC) 208 is connected to and communicates with an external device via a network, and executes communication control processing in the network. For example, Internet communication using TCP / IP is possible.

  The position information positioning device 212 measures the current position of the mobile terminal device 110. For example, it is comprised from GPS, an electronic compass apparatus, etc. Alternatively, the approximate current position can be determined based on the radio wave intensity and SSID information of the access point information of the neighboring wireless LAN via the communication I / FC 208. The location information positioning device 212 is not necessarily required for the mail receiving server 100.

  Note that the CPU 201 enables display on the display device 210 by executing, for example, outline font rasterization processing on a display information area in the RAM 202. Needless to say, the hardware configuration illustrated in FIG. 2 is not necessarily required as long as various processes described below can be performed. The above is the description of the hardware configuration of the mobile terminal device 110 in the embodiment of the present invention of FIG.

  Next, the mail receiving process in the mail receiving server 100 will be described with reference to FIGS. First, with reference to FIG. 3, the mail receiving process of the mail receiving server 100 in the embodiment of the present invention will be described. FIG. 3 is a flowchart showing the mail receiving process of the mail receiving server 100 in the embodiment of the present invention.

  3 is performed by the CPU 201 of the mail receiving server 100, the CPU 201 of the mobile terminal device 110 may perform the processing in the mobile terminal device 110.

  In step S301 of FIG. 3, when the mail receiving unit 101 receives an e-mail from an external mail server, the CPU 201 of the mail receiving server 100 initializes the position information list (step S301). The location information list is an area for temporary storage and aggregation processing of descriptions related to location information extracted in received mail analysis processing described later.

  In the subsequent step S302, the CPU 201 of the mail receiving server 100 performs an analysis process on the received electronic mail (step S302). The received mail analysis process in step S302 will be described later with reference to FIG.

  Here, with reference to FIG. 4, an example of the received mail analysis processing of the mail receiving server 100 in the embodiment of the present invention will be described. FIG. 4 is a flowchart showing received mail analysis processing of the mail receiving server 100 according to the embodiment of the present invention.

  4 is performed by the CPU 201 of the mail receiving server 100, the CPU 201 of the mobile terminal device 110 may perform the processing in the mobile terminal device 110.

  In step S401 of FIG. 4, the CPU 201 of the mail receiving server 100 performs processing for analyzing the mail address described in the header part of the e-mail (step S401). The mail address analysis process in step S401 will be described later with reference to FIG.

  Here, with reference to FIG. 5, an example of the mail address analysis process in the embodiment of the present invention will be described. FIG. 5 is a flowchart showing mail address analysis processing in the embodiment of the present invention.

  Here, the processing in FIG. 5 is performed by the CPU 201 of the mail receiving server 100, but the CPU 201 of the mobile terminal device 110 may perform the processing in the mobile terminal device 110.

  The e-mail address described in the header part of the e-mail exists mainly in the From part representing the sender and the To part or Cc part representing the recipient. In step S501 of FIG. 5, the CPU 201 of the mail receiving server 100 performs mail address analysis processing for all mail addresses described in the header part of these electronic mails (step S501).

  The description format of the mail address can be described in the form of ““ name ”<mail address>” in addition to the case where the mail address itself is used. In this case, “name” and “mail address” can be associated with each other.

  In step S502, the CPU 201 of the mail receiving server 100 determines whether “name” is included in the mail address description (step S502). If “Yes” in step S502, that is, if the e-mail address description includes name information, the process proceeds to step S503.

  In step S503, it is searched whether or not the mail address is registered in the database unit 105 (step S503). If the e-mail address is not registered ("No" in step S503), the process proceeds to step S504, the e-mail address and the name are registered in the database unit 105 in association with each other (step S504), and the process proceeds to step S505. .

  If the e-mail address description does not include name information (if “No” in step S502), or if the e-mail address is already registered in the database unit 105 (“Yes” in step S503), the process proceeds to step S505. .

  In a succeeding step S505, it is determined whether or not the mail address description is a description of the From part (step S505). If “YES” in step S505, that is, if the mail address description is a sender, the process proceeds to step S507, and the mail address is added as sender information to the position information list (step S507). Details of the position information list will be described later with reference to FIG.

  Here, an example of the position information list in the embodiment of the present invention will be described with reference to FIG. FIG. 9 is a diagram showing an example of the position information list in the embodiment of the present invention.

  The position information list 900 is stored in the external memory 211 of the mail receiving server 100 in this description, but may be stored in the external memory 211 of the mobile terminal device 110. The position information list 900 includes an extracted character string 901, an extraction location 902, a state 903, a key 904, and longitude / latitude information 905, as shown in FIG.

  The extracted character string 901 is a description extracted from the electronic mail. For example, in the case of the mail address description described above, the mail address is stored as shown in FIG.

The extracted location 902 indicates the location where the extracted character string 901 is extracted. For example, in the case of the email address description described above, if the sender information is the sender information, as shown in FIG. Saved.

The state 903 is used in the position information aggregation process. In the case of the email address description described above, the status email address is saved. The position information aggregation process will be described later with reference to FIG.

A key 904 is used to extract the extracted character string 901 from a document using a keyword. Used to extract from the document anything other than a clear extracted character string, such as an email address or address string. The key 904 will be described later with reference to FIG.

  Here, with reference to FIG. 10, an example of a keyword set for aggregating position information in the embodiment of the present invention will be described. FIG. 10 is a diagram illustrating an example of a keyword set for position information aggregation in the embodiment of the present invention.

  As shown in FIG. 10, the keyword set 1000 for position information aggregation includes a keyword 1001 and an attribute 1002.

  The keyword set 1000 may be stored in the external memory 211 of the mail receiving server 100, or may be stored in the external memory 211 of the mobile terminal device 110. Here, it is assumed that the keyword set 1000 is stored in the external memory 211 of the mail receiving server 100.

  In this description, the keyword set for collecting location information is not a word indicating a place by itself, or a destination indicating a place differs depending on a situation, and is combined with other information of the e-mail. Means a keyword that can clearly indicate the location.

For example, in the case of the keyword “our company” in FIG. 10, it is not possible to specify the organization of the organization by the word alone, but the organization indicated by the keyword “our company” can be specified together with the sender information of the e-mail. Therefore, in the case of the keyword “our company”, “from” indicating the sender is defined by the attribute 1002. Similarly, in the case of the keyword “your company”, the attribute 1002 defines “to” indicating the recipient.

An example of an embodiment using the keyword “our company” is shown. If there is a “meeting in our conference room” in the body of the email, the keyword “our company” can be found by pattern matching, and it can be determined that the sender information is by referring to the attribute 1002.

  In this case, the position information specified from the keyword “our company” is determined to be position information indicated by the address of the company that sent the mail, which is included in the signature of the mail. An extraction method for obtaining the extracted character string “in our conference room” from the character string will be described later with reference to FIG.

The above is an explanation of an example of a keyword set for location information aggregation in the embodiment of the present invention in FIG.

Returning to the description of FIG. The longitude / latitude information 905 quantifies and stores the longitude / latitude of the place indicated by the extracted character string 901. The conversion process from the extracted character string 901 to the longitude / latitude information 905 will be described later with reference to FIG.

The above is an explanation of an example of the position information list in the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. If “NO” in step S505, that is, if the mail address description is a To part or a Cc part, the CPU 201 of the mail receiving server 100 proceeds to step S506, and the mail information is stored in the position information list as recipient information. An address is added (step S506).

  As described above, all the mail address descriptions described in the header part are added to the position information list by the processing from step S501 to step S508. The above is an explanation of an example of the mail address analysis process in the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. The CPU 201 of the mail receiving server 100 proceeds with the process to step S402, and determines whether or not the body part of the e-mail is in the multipart format (step S402). If it is in the multi-part format (“Yes” in step S402), the process proceeds to step S403.

  From step S403 to step S410, analysis processing is individually performed for all parts. Proceeding to step S404, it is checked whether the part is the first part of the multipart, that is, the mail body part (step S404). When it is the first part (in the case of “Yes” in step S404), the process proceeds to step S405, and text analysis processing is performed (step S405).

  The body text analysis process is a process of adding information obtained by analyzing the text of an e-mail to the position information list 900 described above. The text analysis process will be described later with reference to FIG. After the body text analysis process, the process returns from step S410 to step S403 to start the analysis process for the next part.

  Since all the second and subsequent parts are “No” in step S404, the CPU 201 of the mail receiving server 100 proceeds with the process to step S406, and determines whether text can be extracted from the part (step S406). The criterion is a data format described in the Content-Type part of the part.

  For example, when “image / jpeg” is included in the Content-Type portion of the part, it is understood that an image file is attached. If valid text information can be extracted by performing OCR analysis processing on the image file (“Yes” in step S406), the process proceeds to step S407. Alternatively, if an image file is attached, it can be determined that text extraction cannot be performed (“No” in step S406), and the process can proceed to step S410.

It is desirable that the text extraction possibility determination according to the data format of the content-type part of the part can be selected depending on the setting of the mail receiving server 100 or the presence or absence of a text extraction library program corresponding to the data format.

  When valid text information can be extracted (in the case of “Yes” in step S406), the CPU 201 of the mail receiving server 100 proceeds to step S407 and performs text extraction processing for the part (step S407). As described above, text information is extracted using various text extraction library programs, and the process proceeds to step S408. If the data format is a text format, nothing is done and the process proceeds to step S408.

  In step S408, the CPU 201 of the mail receiving server 100 performs text analysis processing on the extracted text information (step S408). The text analysis process is a process for extracting a description related to location information from a text, such as a character string indicating an address itself (hereinafter referred to as an address character string), an organization name, a store name, a station name, a public facility name, or the like. A keyword that can specify the location (hereinafter referred to as a location keyword) or a location that can be estimated to indicate the location as a result of analysis by language processing (hereinafter referred to as language processing estimation).

  The address character string or the location keyword can be extracted by simple pattern matching by registering in advance in the database unit 105, or attribute information as a result of morphological analysis in language processing to be described later. It is also possible to extract the character string by referring to it, or extract the character string from the dependency analysis result.

  In the language processing estimation, a morpheme sequence is obtained by performing morphological analysis on the text. In the current general morpheme analysis program, various attribute information is added in addition to the part of speech information. For example, name attribute information, place name attribute information, and the like are added to the morpheme. With reference to such attribute information, for example, it is possible to determine a morpheme string having a place name attribute as a character string representing an address, or to determine a morpheme string having a name attribute as a character string representing a name. is there. In this case, it is assumed that the process for specifying the position information directly from the morpheme string having the name attribute is not performed. For example, it is not judged that Mr. A = A prefecture.

  Moreover, the dependency structure of a sentence can be obtained by performing syntax analysis, and it becomes possible to extract the information regarding a place more correctly. For example, FIG. 7 shows a dependency analysis result obtained from a sentence “I will make a meeting in our conference room”.

  Here, with reference to FIG. 7, an example of the result of the dependency analysis in the embodiment of the present invention will be described. FIG. 7 is a diagram illustrating an example of a dependency analysis result according to the embodiment of the present invention. The dependency structure is one of the results of the parsing, and indicates which character string in the sentence is related to which character string and the structure of the modification relationship in the sentence.

  FIG. 7 shows that, for example, the character string 701 “Meeting” has a structure related to the character string 705 “I will do it”. Further, “room”, which is a partial morpheme of the character string 704 “room”, has a place attribute as morpheme attribute information. Therefore, it is possible to extract a character string related to a place by following a portion related to the character string 704 “in the room”. From the character string 704 “in the room”, the character string 703 “meeting” and the character string 702 “our company” can be traced, and the character string “in our meeting room” can be extracted.

  Further, as a result of the dependency analysis, when time information that is date and time information is confirmed in the character string related to the extracted character string, the time information is associated with the position information list 900 and mail Store in the external memory 211 of the receiving server 100. The above is an explanation of an example of the result of dependency analysis in the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. The CPU 201 of the mail receiving server 100 extracts a description about the location from the text using the address character string obtained as a result of the analysis in step S408, the location keyword, or the language processing estimation, and in the subsequent step S409, The extracted character string is added to the position information list together with the extracted part (step S409).

  The CPU 201 of the mail receiving server 100 advances the process to step S410, and if the analysis has not been completed for all parts, the process returns to step S403, and analysis of the next part is started. If the analysis of all parts has been completed, the received mail analysis process ends.

  If “NO” in step S402, the e-mail is not a multi-part, so only the body analysis (step S411) is performed. The above is an example of the received mail analysis process of the mail receiving server 100 in the embodiment of the present invention shown in FIG.

  Next, the flow of text analysis processing in the embodiment of the present invention will be described with reference to FIG. FIG. 8 is a flowchart showing text analysis processing in the embodiment of the present invention. The description in this drawing corresponds to the details of step S405 and step S411 in FIG.

  8 is performed by the CPU 201 of the mail receiving server 100, the CPU 201 of the mobile terminal device 110 may perform the process in the mobile terminal device 110.

  The CPU 201 of the mail receiving server 100 determines whether the e-mail subject to text analysis is a reply mail to an arbitrary mail or a transfer mail for transferring an arbitrary mail (step S801). . If it is not a reply mail or a forward mail ("No" in step S801), the process proceeds to step S803. If it is a reply mail or a forward mail ("Yes" in step S801), the process proceeds to step S802, and the reply / forwarding unit is removed so that the portion is not subject to text analysis (step S802).

In subsequent step S803, text analysis of the e-mail is executed (step S803). Note that the text analysis in step S803 is the same as the text analysis (step S408) in FIG. 4 described above, and a description thereof will be omitted here.

  In subsequent step S804, the CPU 201 of the mail receiving server 100 performs a signature column determination process (step S804). In the signature column determination process, a signature part written at the end of the mail body is extracted.

As described above, since the e-mail address analysis process has been performed in step S401 of FIG. 4, at least the e-mail address of the sender is determined at the start of the signature field determination process and stored in the position information list. Has been. Therefore, in the signature field determination process, the end of the mail text is determined from the mail address having the sender attribute stored in the position information list or the name information obtained by searching the database unit 105 using the mail address as a key. It is possible to extract the signature information in the part.

  When the signature area to be extracted is restricted, the setting information of the mail receiving server 100 is restricted with an arbitrary number of lines, or the final part having no sentence structure as the result of parsing the mail body is the signature area. Can be specified as

  Subsequently, in step S805, the CPU 201 of the mail receiving server 100 adds information obtained by text analysis to the position information list in the same manner as in step S409 in FIG.

S805). At this time, referring to the analysis result in step S803 and the signature field determination result in step S804, if the extracted portion of the extracted character string is included in the signature part, the extraction location is changed to “signature”. Add to the location information list.

  Through the above-described received mail analysis process, the location information written in the electronic mail is stored in the position information list. The above is the description of the flow of text analysis processing in the embodiment of the present invention in FIG.

  Returning to the description of FIG. The CPU 201 of the mail receiving server 100 analyzes the electronic mail in step S302 and collects the position information list (step S303).

  Here, with reference to FIG. 6, the state transition of the positional information aggregation process in the embodiment of the present invention will be described. FIG. 6 is a diagram showing a state transition of the position information aggregation process in the embodiment of the present invention.

  The position information is defined as consisting of longitude and latitude. In FIG. 6 showing the state transition of the aggregation method, position information 607 is set as the final state. The purpose of use of the state transition diagram in FIG. 6 is to acquire longitude / latitude information by making various information extracted from the electronic mail transition as much as possible to the position information 607 using FIG.

  For example, when a sentence describing an address is extracted from an e-mail, a state is set in the address 605 in FIG. 6, and position information 607 can be obtained according to the state transition diagram. Although it is not difficult to imagine that it is easy to obtain the position information 607 from the address 605, for example, it is clear that a conversion database from address to longitude / latitude information such as a geocoding service is necessary. is there.

Such a conversion database may use the above-described geocoding service, or may be provided on the database unit 105 on the mail receiving server 100 or on another server in the network.

  Next, an e-mail sender will be described. The sender of the e-mail is described as a mail address in the header part of the e-mail. When the mail address is extracted from the electronic mail, the state is set to the mail address 601 in FIG.

  From the email address 601, a transition to an organization name 603 and a transition to a name 602 associated with the email address 601 are defined by referring to the domain name of the email address.

  For example, when the e-mail address extracted in the database installed in the external memory 211 of the e-mail receiving server 100 has been registered, the name 602 and the organization name 603 corresponding to the e-mail address can be specified from the e-mail address. .

  Further, it is possible to acquire an address registered in the address book or the like of the external memory 211 corresponding to each of the name 602 and the organization name 603 and set it as a state in the address 605 to acquire the position information 607. is there.

  Furthermore, the location information 607 can be acquired via the address 605 by acquiring the location information from the keywords extracted from the mail (for example, description of the meeting location) and setting the status in the location 606. Similarly, the name 602 and the organization name 603 can be specified from the keyword, and the position information 607 can be acquired.

  In addition, for example, when an organization name 603 “Co., Ltd. A” is identified from the keyword 604 “our company”, an address “Co., Ltd. xx prefecture XX city” is described in the e-mail signature column. If there is, the position information 607 indicated by the keyword 604 “our company” can be specified via the address 605 extracted from the e-mail. The above is the description of the state transition of the position information aggregation processing in the embodiment of the present invention in FIG.

Returning to the description of FIG. The CPU 201 of the mail receiving server 100 writes the position information in the extension header of the e-mail (step S304). When the time information of the e-mail is specified by the text analysis described above, the time information is similarly written in the extension header of the e-mail. Details of the extension header will be described later with reference to FIG.

Here, an example of the extension header in the embodiment of the present invention will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of the extension header in the embodiment of the present invention.

As shown in FIG. 11, the extension header 1100 is composed of an extension header name “X-GPS-Priority”, as its value, longitude / latitude information calculated by the above-described position information aggregation processing, and a unique numerical value indicating an extraction location. The The longitude / latitude information is the longitude / latitude information 905 shown in FIG. Further, the unique numerical value indicating the extraction location is a numerical representation of the extraction location 902 shown in FIG.

The extension header 1100 is referred to in the position information evaluation process of the mobile terminal device 110. The position information evaluation process will be described later in detail with reference to FIG. The above is an explanation of an example of the extension header in the embodiment of the present invention shown in FIG.

Returning to the description of FIG. The CPU 201 of the mail receiving server 100 saves and stores the electronic mail in the external memory 211 or the like (step S305).

  If a plurality of pieces of position information are specified and collected by the position information collection process in step S303, the plurality of pieces of position information specified and collected in step S303 are written in the extension header when the extension header is written in step S304. It may be.

  In addition, by incorporating a character string that indicates which state information 903 and position information identified and aggregated based on the extraction location 902 into the extension header, You may make it make a portable terminal device judge which position information of position information should be used for calculating the later-described evaluation information.

  In addition, this is a table in which priority levels indicating which position information identified and aggregated based on the state 903 and extraction location 902 of the aggregated position information is preferentially written to the extension header 1100 is written. By providing the illustrated priority order table or the like, it may be determined which position information is written in the extension header 1100.

  The priority order table is, for example, a table in which the combination of the state 903 and the extraction location 902 is associated with the priority order. That is, in the location information aggregation process of step S303, there is location information aggregated based on the mail address of the transmission source and location information aggregated based on the keyword, and the two location information is different. The priority table indicates “1” for the combination of “extracted part = text” and “state = keyword”, and the priority of the combination of “extracted part = From header” and “state = email address” is “1”. In the case of 2 ″, the position information written in the extension header is the position information aggregated based on the keyword.

  The above is the description of the mail reception processing of the mail reception server 100 in the embodiment of the present invention shown in FIG.

  Next, with reference to FIG. 12, the mail acquisition process of the portable terminal device 110 in the embodiment of the present invention will be described. FIG. 12 is a flowchart showing mail acquisition processing of the mobile terminal device 110 according to the embodiment of the present invention.

  Here, the processing in FIG. 12 is performed by the CPU 201 of the mobile terminal device 110, but the CPU 201 of the mail receiving server 100 may perform the processing in the mail receiving server 100.

  The CPU 201 of the mobile terminal device 110 acquires unread mail to the mail receiving server 100 according to a user's instruction, or is automatically read to the mail receiving server 100 at regular time intervals by a program operating in the mobile terminal device 110. May get mail.

  In the mail acquisition process, in step S1201, the CPU 201 of the mobile terminal device 110 inquires whether there is an unread mail in the mail receiving server 100 (step S1201). If there is no unread mail (“No” in step S1201), the process proceeds to step S1203.

  When there is an unread mail (in the case of “Yes” in step S1201), the process proceeds to step S1202, and the CPU 201 of the mobile terminal device 110 is the mail acquisition unit 112 and the mail storage unit 104 (external memory 211 or the like) of the mail receiving server 100. The user's unread mail is acquired (step S1202), and the process proceeds to step S1203.

  In steps S1203 to S1205, the position information evaluation process is performed in step S1204 for the unread mail newly acquired in step S1202 and all the unread mail acquired through the mail acquisition process but not yet viewed by the user. Here, it is described that the position information is evaluated for the unread mail, but the position information evaluation process may be performed for the read mail. Hereinafter, for the part describing unread mail, for example, processing may be applied only to read mail, or processing may be applied to both read mail and unread mail. Also good.

  Here, with reference to FIG. 13, the positional information evaluation process of the portable terminal device 110 in embodiment of this invention is demonstrated. FIG. 13 is a flowchart showing position information evaluation processing of the mobile terminal device 110 according to the embodiment of the present invention.

  Here, the processing in FIG. 12 is performed by the CPU 201 of the mobile terminal device 110, but the CPU 201 of the mail receiving server 100 may perform the processing in the mail receiving server 100.

  In the position information evaluation process, the position information obtained by the current position positioning unit 111 of the mobile terminal device 110 is compared and evaluated with respect to the position information described in the extension header in step S304 of FIG.

In step S1301, it is checked whether or not an extension header is added to the mail that is the position information evaluation processing target (step S1301). If the extension header has not been assigned (“No” in step S1301), the position information evaluation process ends.

When the extension header is added (in the case of “Yes” in step S1301), the process proceeds to step S1302, and the current position positioning unit 111 measures and acquires the position information of the current position (step S1302). The current location positioning unit 111 may perform positioning with high accuracy using a GPS function, or may determine an approximate position from an access point of a surrounding wireless LAN, radio wave intensity, and the like.

  13 is the mail receiving server 100, in step S1302, the CPU 201 of the mail receiving server 100 receives and acquires the current position information of the mobile terminal device 110 from the mobile terminal device 110.

  In subsequent step S1303, it is confirmed whether or not the current location information measured in step S1302 has moved since the previous positioning (step S1303). That is, if there is no movement of the current location since the previous position information evaluation process was performed (in the case of “Yes” in step S1303), the position information evaluation process ends. If the current location has been moved (NO in step S1303), the process proceeds to step S1304.

  In subsequent steps S1305 to S1308, position information evaluation is performed for all extension headers attached to the position information evaluation target mail (step S1304).

  Proceeding to step S1305, the difference between the position information described in one extension header and the position information measured in step S1302 is calculated as evaluation information (step S1305). The evaluation information here is, for example, information on the distance between the places indicated by the two pieces of position information.

  The evaluation information calculation method is a method of calculating a linear distance from two longitudes and latitudes (linear distance method), or by extracting the nearest station for each of the two longitudes and latitudes and the travel time between the nearest stations. There are a method (calculation distance method) for calculating travel time on a map by referring to road information for two longitudes and latitudes (a map distance method).

  As the linear distance method, a publicly available calculation method can be used. The public institution distance method and the map distance method can be calculated by installing a program or data in the mobile terminal device 110, or the longitude / latitude information is transmitted to an external server to calculate the travel time. A scheme is also possible.

  In addition, when there are a plurality of pieces of position information described in the extension header, the position information in the extension header that is closest to the position of the mobile terminal device 110 among the position information, and the position of the mobile terminal device 110 The evaluation information may be calculated using information.

  Further, when it is possible to specify which state 903 and position information 903 are aggregated and specified based on the extraction location 902, the priority table (not shown) described above in the description of step S303. Based on the above, it may be determined which of the position information in the extension header is used to calculate the evaluation information.

  In subsequent step S1306, it is confirmed whether or not the number of evaluation information histories stored is within a limit value (step S1306). Although the calculated evaluation information is stored in the mobile terminal device 110, the number of stored information is limited, and a mail display method using the storage history is disclosed in the mail display processing described later.

  If the number of evaluation information histories stored is within the limit value (if “Yes” in step S1306), the process proceeds to step S1308, and the calculated evaluation information is stored (step S1308). The evaluation information is stored for each extension header. If the stored number of evaluation information histories is not within the limit value (if “NO” in step S1306), the process proceeds to step S1307, the required number of oldest evaluation information is deleted (step S1307), and then the process proceeds to step S1308. The evaluation information is saved (step S1308).

  Proceeding to step S1309, steps S1305 to S1308 are repeated until evaluation information is calculated from all extension headers.

  When the evaluation of all the extension headers is completed, the process proceeds to step S1310, and representative evaluation information is selected (step S1310). The representative evaluation information is the evaluation information calculated in steps S1305 to S1308 that has the best evaluation, that is, the position information that is determined to be the closest among the current position and the position information of the mail.

  The representative evaluation information may be determined according to the priority order in which the position information is used as the representative evaluation information in the priority table (not shown). The above is the description of the position information evaluation process of the mobile terminal device 110 according to the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. When the position information evaluation process for all unread mails ends, the mail acquisition process ends (step S1205). The above is the description of the mail acquisition process of the mobile terminal device 110 in the embodiment of the present invention of FIG.

  Next, mail display processing of the mobile terminal device 110 in the embodiment of the present invention will be described using FIG. FIG. 14 is a flowchart showing mail display processing of the mobile terminal device 110 according to the embodiment of the present invention. The mail display process is a process when the user of the mobile terminal device 110 performs mail browsing mainly on unread mail.

  14 is performed by the CPU 201 of the mobile terminal device 110, the CPU 201 of the mail receiving server 100 may perform the processing in the mail receiving server 100. In this case, only the display processing in step S1409 is executed by the CPU 201 of the portable terminal device 110 having a display screen, and the processing from step S1401 to step S1408 is executed by the CPU 201 of the mail receiving server 100.

  In step S1401, the CPU 201 of the mobile terminal device 110 checks the mail display mode of the mobile terminal device 110 (step S1401). When the mail display mode is not the position information priority display mode (in the case of “No” in step S1401), the process proceeds to step S1408, and it is determined to perform normal mail display (step S1408).

  In step S1409, the CPU 201 of the mobile terminal device 110 executes normal display processing according to the determination in step S1408. In the normal display process, a display operation similar to that of a general mail program, for example, arranging in the order of the transmission time of the mail is performed.

  When the position information priority display mode is set (in the case of “Yes” in step S1401), the process proceeds to step S1402, and the processing from step S1403 to step S1407 is performed for all unread mails (step S1402). That is, one mail is acquired from the unread mails, the processes from step S1403 to step S1407 are performed on the one mail, and when the unread mail becomes 0, the process proceeds to step S1409.

  In step S1403, the above-described position information evaluation process (see FIG. 13) is performed (step S1403). If there is a difference between the current location when the mail acquisition process in FIG. 12 is performed and the mail display process in FIG. 14 is performed, the position information evaluation process is performed (determined in step S1303 in FIG. 13).

  In subsequent step S1404, it is confirmed whether or not there is a history of the evaluation information calculated in the position information evaluation process described above (step S1404). If there is no history (“No” in step S1404), the process proceeds to step S1407.

  In the position information priority display in step S1407, in order to perform the mail list display based on the representative evaluation information obtained in the position information evaluation process, not the normal display as shown in step S1408 in the mail list display. The priority order is determined (step S1407).

  For example, for unread emails, an icon list is used so that the list of emails is displayed in order of good representative evaluation information (that is, in order of proximity to the current location), and the representative evaluation information is displayed when the list is displayed. Or a decorative display such as displaying with a color or character decoration different from other mail is desirable.

  Here, it is assumed that a sort process is executed so that electronic mails are displayed in the mail list in the order of good representative evaluation information (that is, the order close to the current location). The order after sorting is called sort order. The determination of the sort order (priority display order determination) will be described later with reference to FIG.

  Here, with reference to FIG. 15, the details of the priority display order determination processing in the embodiment of the present invention will be described. FIG. 15 is a flowchart showing details of the priority display order determination processing in the embodiment of the present invention.

  The CPU 201 of the mobile terminal device 110 acquires current time information using a clock function or the like mounted on the mobile terminal device 110. The time information is information indicating date and time (step S1501). Then, it is determined whether or not time information can be acquired from one of the unread mails acquired in step S1402 of FIG. 14 (step S1502). That is, whether or not time information is included in the extension header 1100 is determined. judge.

  If it is determined that the time information can be acquired (YES in step S1502), the time information is acquired as time information of the e-mail (step S1503), and the time information of the e-mail is acquired in step S1501. It is determined whether the time after the time information is indicated (step S1504).

  If the CPU 201 of the mobile terminal device 110 determines that the time information of the e-mail indicates a time later than the current time information acquired in step S1501 (YES in step S1504), Sorting is performed using the representative evaluation information selected in step S1310 of step 13 (step S1505). For example, in order to display e-mails in order from an e-mail having position information indicating a position close to the current position, the e-mail is information on a distance farther than the distance between the position information of the e-mail and the current location (evaluation information) The emails are sorted so that the emails having priority are displayed with priority. “Preferential display” means, for example, displaying the e-mail above the other e-mails.

  If it is determined that the time information of the e-mail indicates the time before the current time information acquired in step S1501 (NO in step S1504), the e-mail is sorted based on the reception time (step S1507). ). For example, the e-mails are sorted so that the e-mails are displayed in order of the reception time.

  Here, the emails sorted in step S1505 and the emails sorted in step S1507 are treated as different email groups. For example, the list of e-mails sorted in step S1505 is identified as sort group 1 and the list of e-mails sorted in step S1507 is distinguished as e-mails belonging to sort group 2, and the storage area such as the external storage memory 211 of the mobile terminal device 110 Temporarily store.

  The CPU 201 of the mobile terminal device 110 determines whether or not the sorting process for all unread mails has been completed (step S1506). If it is determined that the sorting process has not ended (NO in step S1506), the process is performed as shown in FIG. Return to step S1402. If it is determined that the process has been completed (YES in step S1506), the process proceeds to step S1508, and the sort group 1 e-mail is sorted to be displayed with priority over the sort group 2 e-mail. (Step S1508), the mail display order is determined (Step S1509).

  For example, if there is “Meeting at our conference room from 15:00” in the body of the email, the location information of the company indicated by “our company” from the key 904 “our company” The location information of the company that sent the mail is specified from the address described in the signature column or the address corresponding to the mail address of the sender of the electronic mail in the address book.

  In addition, information indicating a time of “15:00” is specified as time information from the text. Furthermore, the current time information and the current position information of the mobile terminal device 110 are acquired, and the e-mail that is the identification source of the time information after the current time information or after the current time information, Control is performed so that the e-mail that is the identification source of the position information closest to the current position information of the mobile terminal device 110 is displayed on the display screen in preference to other mails.

  That is, for example, when there is an e-mail A having position information of 100 m from the current position of the mobile terminal device 110 and an e-mail B having position information of 200 m, in the present invention, the e-mail A, Although displayed on the display screen in the order of mail B, the time information specified from the electronic mail A (for example, the start time of the meeting) has passed the current time, the time information and the position of 100m When the information has a relevance such as acceptance, the e-mail A is not determined to be preferentially displayed with respect to the e-mail B, and the display screen displays the e-mail B and the e-mail A. Mail will be displayed in the order of.

  By doing so, it is possible to specify an e-mail that does not need to be displayed preferentially, such as when the e-mail requirement is related to the past. The above is the description of the details of the priority display order determination processing in the embodiment of the present invention in FIG. In the description of the present embodiment, as described above, the e-mail related to the past (the e-mail having time information prior to the current time) is assumed not to be sorted based on position information and distance. However, for example, the processing of steps S1501 to S1504, step S1507, and step S1508 in FIG. 15 may not be performed, and e-mail sorting and display order determination may be performed in step S1505. That is, emails may be sorted using position information and distance information without using time information. On the other hand, without using the position information and the distance information, the time information specified from the e-mail (for example, the time information written in the extension header in step S304) is used to sort and display the e-mail. A decision may be made.

  Further, when the time information specified from the e-mail indicates a time that is more than a certain time, for example, when the time information indicates 24 hours or more, the position information specified from the e-mail is determined from the current position of the mobile terminal device 110. Even if the position is closer than the position information of other mail, it may be determined that the e-mail does not need to be displayed with priority over other mail.

  In this case, a time priority table such as a display priority table based on time information is provided in the external memory 211 or the like and stored in the time priority table. (See time priority table 1700 in FIG. 17).

  In this case, the external memory 211 in which the time priority table is stored may be the external memory 211 of the mail receiving server 100 or the external memory 211 of the mobile terminal device 110.

  In the time priority table, for example, “distance”, which is the difference between the mobile terminal device 110 and the position specified from the e-mail, and the difference between the current time and the time specified from the e-mail “ Assume that a combination condition (display combination condition) of “time difference” and “priority order” that determines display priority is registered. (Corresponding to distance 1701, time difference 1703, priority 1704 in the time priority table 1700 of FIG. 17).

  Here, with reference to FIG. 17, an example of the structure of the time priority table in the embodiment of the present invention will be described. FIG. 17 is a diagram showing an example of the configuration of the time priority table in the embodiment of the present invention. The time priority table 1700 is assumed to be set in advance. Each value of the time priority order table 1700 can be arbitrarily set according to an instruction from the user via the display screen.

  As shown in FIG. 17, the time priority order table 1700 includes a distance 1701, a time relation 1702, a time difference 1703, a priority order 1704, and the like. The time priority order table 1700 of FIG. 17 has a combination condition that combines a distance 1701, a time relation 1702, and a time difference 1703, and sets rules for determining the priority order of displaying e-mails that match each condition. It is data. As described above, the distance 1701 is a distance that is a difference between the position of the mobile terminal device 110 and the position specified from the e-mail.

  The time relation 1702 indicates whether the time information acquired from the e-mail indicates after (after) the current time or before (before) the current time. As described above, the time difference 1703 indicates a time difference that is a difference between the current time and the time specified from the electronic mail. As described above, the priority order 1704 indicates the priority order for determining the priority of display of e-mails that satisfies the conditions of the distance 1701, the time relation 1702, and the time difference 1703.

  If not used as a condition or condition, a null value is set. For example, when sorting e-mails based on only the distance 1701, a null value is set for the time relation 1702 and the time difference 1703. In the present embodiment, e-mails that do not meet the conditions set in the priority table 1700 are displayed in the order of reception date and time after e-mails that match the conditions set in the priority table 1700. And

  In this embodiment, when there are two or more unread e-mails within a distance of 1701 = 1 km, the e-mails are sorted in ascending order of distance. Further, when there are two or more e-mails within the time difference 1703 = 24h, the e-mails are sorted in ascending order of the time difference. This is the same even if the values of the distance 1701 and the time difference 1703 are different from the above.

  For example, in the time priority table, “distance = 1 km or less” + “time difference = currently within one day” + “priority = 1” and “distance = 1 km” “time difference = currently within three days” + When registered as “priority = 2”, among the e-mails of the location information specifying source within a distance of 1 km from the current location, the specifying source of the time information within one day (24h) after the current time The e-mails are sorted to be displayed preferentially with respect to e-mails from which time information is acquired within 3 days (72h) before the current time.

  In this case, mails that do not match the combination conditions registered in the time priority table are sorted to be displayed after the mails that match the combination conditions registered in the time priority table. The above is an example of the configuration of the time priority table in the embodiment of the present invention shown in FIG. It should be noted that the e-mail is sorted and the display order is determined using the time information specified from the e-mail (for example, the time information written in the extension header in step S304) without using the position information and the distance information. For example, in the time priority table 1700 of FIG. 17, “distance 1701 = null, time relationship 1702 = after, time difference 1703 = 24h, priority 1704 = 1” and “distance 1701 = null, time relationship 1702 = before, time difference If “1703 = 72h, priority 1704 = 2” is set, the e-mail has time information after the current time, and the time information is given priority to an e-mail within 24 hours from the current time. Display and then an email with time information before the current time, where the time information is the current time E-mail within et al 72 hours to be displayed by priority. In this case, for example, the processes of steps S1504, S1507, and S1508 in FIG. 15 are not performed, and instead of the current step S1505, the e-mails are sorted in ascending order of the time difference between the time information specified from the e-mail and the current time. Execute.

  Returning to the description of FIG. The CPU 201 of the mobile terminal device 110, when the e-mail evaluated in step S1403 has a position information evaluation history different from the previous position information evaluation (in the case of “Yes” in step S1404), that is, the unread mail When the position information evaluation process is performed in step S1204 in FIG. 12 before the mail display process is performed (before the position information evaluation process in step S1204 in FIG. 12 performed immediately before), step S1405 is performed. Proceed to

  The highlighting process in step S1405 is basically the same as the position information priority display shown in step S1407. At this time, it is determined to display the unread mail by emphasizing the unread mail having a plurality of evaluation information, that is, the change of the evaluation information accompanying the movement of the user (step S1405).

  For example, when the evaluation value in the arbitrary evaluation information of the mail is selected as the representative evaluation information in the mail information display process and the position information evaluation process immediately before the mail display, and when the mail display has a better evaluation value, In other words, since it can be seen that the current position has moved closer to the position information described in the extension header that has been evaluated, the decorative display (highlighted display) as described above is further highlighted. Decide what to do.

  As described above, for the highlighting, for example, a method of changing the color of the e-mail or displaying an icon for emphasizing the e-mail can be considered. An example of the mail display method and display screen will be described later with reference to FIG.

  Here, with reference to FIG. 16, an example of the configuration of the mail display screen in the embodiment of the present invention will be described. FIG. 16 is a diagram showing an example of the configuration of a mail display screen in the embodiment of the present invention.

  As shown in FIG. 16, an e-mail display screen 1600 includes an e-mail 1601, a sender 1602, a subject 1603, a place 1604, a date 1605, a received date 1606, an emphasis display unit 1607, an e-mail 1608, an e-mail 1609, an e-mail 1610, and the like. It is configured.

  The e-mail 1601 and the e-mails 1608 to 1610 are unread e-mails. A sender 1602 indicates the sender of the e-mail. A subject 1603 indicates the subject of the e-mail. A place 1604 indicates a place indicating position information of the electronic mail. For example, the character string that is the acquisition source of the representative evaluation information of the electronic mail 1601 is displayed. The character string can be displayed by the CPU 201 of the mail receiving server 100 writing it in advance in the e-mail extension header 1100 and acquiring it by the CPU 201 of the portable terminal device 110. The distance (representative evaluation information) displayed together with the place 1604, for example, “(500 m)” indicates the distance between the position information of the e-mail and the mobile terminal device 110.

  The date and time 1605 is time information specified from the electronic mail 1601 and is time information written in the extension header 1100. The reception date and time 1606 is the reception date and time of the electronic mail 1601. The highlight display unit 1607 is a display unit that displays an icon for highlighting the electronic mail 1601. 16 displays an icon indicating that the mobile terminal is approaching the position indicated by the position information of the e-mail 1601, that is, A Corporation.

  The display order of e-mails on the mail display screen 1600 will be described using the time priority table 1700. FIG. It is assumed that the current date and time is “March 30, 2012 10:15:00”.

  Since the e-mail 1601 and the e-mail 1608 correspond to the priority order 1704 = 1, that is, the distance from the mobile terminal device 110 is within 1 km, and the time information (date and time 1605) of the e-mail is within 24 hours after the current time. Therefore, the e-mail 1609 and the e-mail 1610 are displayed with priority. Further, since the distance between the position indicated by the position information of the e-mail 1601 and the mobile terminal device 110 is closer than the distance to the e-mail 1608, the e-mail 1601 is displayed with priority over the e-mail 1608. .

  Since the e-mail 1609 falls under priority = 2, that is, the distance from the mobile terminal device 110 is within 1 km, and the e-mail time information (date and time 1605) indicates a time within 72 hours before the current time. Therefore, it is displayed with priority over the email 1610.

  Since the e-mail 1610 corresponds to the priority order 1704 = 3, that is, the distance to the mobile terminal device 110 is within 2 km, priority is given to other e-mails whose distance from the mobile terminal device 110 exceeds 2 km. Is displayed. The above is the description of an example of the configuration of the mail display screen in the embodiment of the present invention shown in FIG.

  The time priority order table 1700 is described as being one in the present embodiment, but may be plural. For example, a plurality of time priority tables 1700 in which a plurality of combination conditions are set and display priority levels of e-mails that match the respective conditions are provided, and those rules (time priority table 1700) are provided to the user on a display screen or the like. By making the selection, the display order of the e-mails may be switched according to the rule (time priority table 1700) selected by the user. As a result, for example, “rules for giving priority to display of e-mails having position information at a short distance” as work rules, and “e-mails having position information at a long distance” as premier rules for pleasure. "Rules to display" can be used properly. That is, according to the purpose and application, rules and display order can be used properly.

  For example, by providing a rule selection button on the display screen 1600 and accepting an instruction to press the button, using the rule (time priority table 1700) corresponding to the button, the electronic processing in steps S1401 to S1409 is performed. The mail sort and display process may be re-executed to change the display order of the e-mails. That is, rule A (time priority table 1700-A) not shown is a rule for determining the display order of e-mails based only on position information, and rule B (time priority table 1700-B) not shown. Is a rule for determining the display order of e-mails based only on time information, when accepting the pressing of a button corresponding to rule A on the display screen 1600, the CPU 201 of the mobile terminal device 110 uses only position information. Steps S1401 to S1409 and steps S1505 to S1509 are executed again to switch the display order. When the pressing of the button corresponding to the rule B is accepted on the display screen 1600, the CPU 201 of the mobile terminal device 110 performs the processes of steps S1401 to S1409 and steps S1501 to S1509 using only the time information and switches the display.

  Further, there may be a case where the representative evaluation information selection target is different between the mail information display process and the position information evaluation process immediately before. For example, the location information written in the signature column of the email was close when the email was acquired, but when the email was displayed after the user moved, the location information extracted from the email text was closer This is the case. In such a case, it is determined to perform highlighting that highlights the fact that it has become closer and also indicates that there is representative evaluation information that has become farther away.

  Further, both the highlighting process in step S1405 and the position information priority display in step S1407 refer to an email that has only evaluation information that exceeds the threshold with reference to an arbitrary threshold, that is, an email that has only location information very far from the current location. It is desirable not to display mail using location information.

  Further, for example, the evaluation value in the arbitrary evaluation information of the mail is selected as the representative evaluation information at the time of displaying the mail and the position information evaluation process immediately before the mail, and has a better evaluation value at the time of displaying the mail. In the e-mail, that is, the e-mail from which the current position information is determined to have moved closer to the position information described in the extension header that has been evaluated, the movement distance is Sort processing may be executed to display e-mails in descending order (in order of increasing distance).

  That is, in step S1404 in FIG. 14, whether or not the distance is shortened by acquiring the latest evaluation information and the latest evaluation information for the electronic mail for which the evaluation information is determined to be stored in the history at least twice. Determine. When it is determined that the distance is shortened, the reduced distance (the distance at which the mobile terminal device 110 approaches the position indicated by the position information of the e-mail) is acquired. These processes are executed for all unread mails, and the electronic mails are sorted in descending order of the shortened distance. In this way, an e-mail having position information close to the destination to which the mobile terminal device 110 moves can be displayed with priority over other e-mails. A user who has the mobile terminal device 110 and is moving can check an e-mail that describes the content related to the location and position that the mobile terminal device 110 will exist at.

  Further, for example, in calculating the shortened distance, information on the moving distance from the position of the mobile terminal device 110 when the immediately previous evaluation information is calculated to the position of the current terminal device, and the moving distance is Using the distance indicated by the evaluation information, the mobile terminal device 110 determines whether or not the position indicated by the position information of the e-mail is approaching, and sorts the e-mails in descending order of the approaching distance. May be.

  That is, the immediately preceding evaluation information indicates “2 km”, the distance (movement distance) from the position where the immediately preceding evaluation information is calculated to the current location is 3 km, and the latest (current) evaluation information indicates “1 km”. The pointing to the e-mail X and the previous evaluation information indicates “5 km”, the distance (movement distance) from the position where the previous evaluation information is calculated to the current location is 3 km, and the latest (current) evaluation If there is an email Y whose information points to “2 km”, the mobile terminal 110 determines that the position indicated by the email X has already passed, lowers the display priority, It is determined that the position shown is approaching, and control for increasing the priority is performed.

  Specifically, E-mail X: 2 km (immediate evaluation information) −3 km (movement distance) = − 1 km (latest evaluation information), E-mail Y: 5 km (immediate evaluation information) −3 km (movement distance) = It is +2 km (latest evaluation information), and the email Y with a positive solution is displayed with priority over the email X with a negative solution. By doing so, it is possible to preferentially display an e-mail having position information of a position to which the mobile terminal 110 is directed. In addition to the distance calculation method described here, for example, using the GPS function of the mobile terminal device 110, the position information of the mobile terminal at the time when the previous evaluation information is calculated, and the current It may be determined whether or not the mobile terminal device 110 is approaching the position indicated by the e-mail using the position information and the position indicated by the e-mail. When the calculated movement distances are the same for a plurality of e-mails, the e-mails are sorted in ascending order of the latest evaluation information (distance between the mobile terminal device 110 and the position indicated by the e-mail).

  When the CPU 201 of the mobile terminal device 110 executes the processing of step S1404 and subsequent steps for all unread emails, an email (mail display screen 1600) is determined based on the determination made in the processing of steps S1405 to S1407. Is displayed on the display screen (step S1409), and the process is terminated. If the processing from step S1404 onward is not executed for all unread mails, the process returns to step S1402. The above is the description of the mail display processing of the mobile terminal device 110 according to the embodiment of the present invention shown in FIG.

  In the present embodiment, the mail receiving server 100 specifies location information from the email and stores it as an extended header in association with the email. The mobile terminal device 110 stores the location information of the mobile terminal device 110 and the extension header. Although the evaluation information is calculated using the position information, for example, all the above-described processing may be performed by the mobile terminal device 110.

  Further, for example, in the mail receiving server 100, the location information is specified from the email and stored as an extension header in association with the email, and the location information of the mobile terminal device 110 acquired from the mobile terminal device 110 and the location information of the extension header are stored. May be used to calculate the evaluation information, determine an email to be displayed based on the evaluation information, and transmit the mail to the mobile terminal device 110.

  Further, in this embodiment, the CPU 201 of the mail receiving server 100 and the CPU 201 of the mobile terminal device 110 determine the priority order for displaying e-mails using only the position information specified from the mail. In the above, position information and time information may be used in combination.

  As described above, according to the present invention, it is possible to provide an imaging apparatus, a control method therefor, and a program that enable efficient mail presentation using information acquired from an electronic mail.

  In addition, the present invention can take the form of, for example, a system, apparatus, method, program, or storage medium, and may be applied to a system composed of a plurality of devices. Further, the present invention may be applied to an apparatus composed of one device.

  It should be noted that the configuration and contents of the various data described above are not limited to this, and it is needless to say that they are configured with various contents according to applications and purposes.

  Needless to say, the present invention can also be applied to a case where the present invention is achieved by supplying a program to a system or apparatus. In this case, by reading a storage medium storing a program represented by software for achieving the present invention into the system or apparatus, the system or apparatus can enjoy the effects of the present invention.

  Furthermore, by downloading and reading a program represented by software for achieving the present invention from a server, database, etc. on a network using a communication program, the system or apparatus can enjoy the effects of the present invention. It becomes.

  Hereinafter, which description in the specification corresponds to which description in the claims will be described. The mobile terminal device 110 has a function for displaying a display screen on the display device 210 (display control means). Note that the main body provided with the display control means is not necessarily the portable terminal device 110. For example, a client terminal such as a PC (not shown) may be used.

  The CPU 201 of the mail receiving server 100 extracts the mail address and character string included in the e-mail, and specifies the position information (step S303 / first position information specifying means). The configuration / function corresponding to the first position information specifying unit may be mounted on the mobile terminal device 110.

  The CPU 201 of the mobile terminal device 110 specifies the current location information of the mobile terminal device 110 by the GPS function or the like (step S1302 / second location information specifying means), and the location information specified from the character string or the like of the mail. Then, based on the location information of the mobile terminal device 110, which of the e-mails is preferentially displayed is determined (step S1405, step S1407 / decision means).

  Note that the processing of step S1405 and step S1407 corresponding to the determining means may be provided and executed by the mail receiving server 100. The acquisition of the position information of the mobile terminal device 110 in step S1302 is executed on the mail receiving server 100 side by receiving from the mobile terminal device 110, and the processing in steps S1405, S1407, and S1408 is executed on the mail receiving server side. Thus, the processing of the CPU 201 of the mobile terminal device 110 is performed according to the reception processing for receiving the display order of the emails determined on the mail receiving server 100 side and the determination result of the display method, and the display processing of step S1409 according to the determination results It can be limited to two.

  The CPU 201 of the mail receiving server 100 extracts character information in the e-mail when specifying the first position information from the e-mail (step S407, step S504, step S506, step S507, step S801 / extraction means). . Note that the extraction unit may be included in the mobile terminal device 110.

  When the extracted character string is a character string indicating the position information itself, such as “address” (character string determination means), the CPU 201 of the mail receiving server 100 sets the character string as the address 605 in FIG. Position information 607 (first position information) is acquired (first position information specifying means of claim 6). The character string determination means may be included in the mobile terminal device 110 and determined.

  When the extracted character string is not a character string indicating the position information itself such as “address” (character string determination means), the CPU 201 of the mail receiving server 100 extracts, for example, the keyword 604 that is a character string “our company”. If so, information indicating position information related to the “our company” is acquired (step S409, name 602, organization name 603, address 605, location 606 from the keyword 604 in FIG. 6). The character string determination means may be provided and executed by the mobile terminal device 110. The process of step S409 may be executed by the CPU 201 of the mobile terminal device 110 in the mobile terminal device 110.

  In other words, when the organization name 603 “corporation A” is specified from the keyword 604 “our company”, and the address “corporation A XX prefecture XX city” is described in the signature column of the e-mail. Then, the location information 607 indicated by the keyword 604 “our company” is specified via the signature column address 605 extracted from the e-mail (character string acquisition means), and specified (first location information specification of claim 2) Means) is also possible.

  The character string includes a mail address, a mail text, a signature field, and a character string obtained by reading an attached file attached to an e-mail. When the extracted character string is an e-mail address, the CPU 201 of the e-mail receiving server 100, the extracted address registered in the e-mail receiving server 100 or the address book stored in the external memory 211 of the mobile terminal device 110, or The first position information is specified by referring to address information of an address that matches the domain of the extracted address (corresponding position information storage means, first position information specifying means of claim 5). The corresponding position information storage means may be a person included in the CPU 201 of the mobile terminal device 110.

  Further, which other character string is associated with the character string extracted by the extraction means is specified by dependency analysis shown in FIG. 7 (related character string specifying means, dependency specifying means). In the present embodiment, the related character string specifying unit and the dependency specifying unit are included in the mail receiving server 100 and execute processing, but may be included in and executed by the mobile terminal device 110.

  The CPU 201 of the mobile terminal device 110 calculates the distance between the first position information and the second position information indicating the position of the mobile terminal device 110 (step S1305 / distance calculation means), and the distance is small. The e-mails are sorted in order, and it is determined that the e-mails are displayed on the display screen of the mobile terminal device 110 in the sorted order (step S1407 / deciding means of claim 7). The distance calculating unit and the determining unit may be provided in the mail receiving server 100.

  In addition, when a plurality of pieces of first position information are specified from the e-mail, the character string that is the identification source of each first position information, the extraction location 902 as the group to which the character string belongs, and the state 903 are the mail receiving server 100. Thru | or the character string conditions which are the character strings set to the priority order table (condition memory | storage means) not shown memorize | stored in the external memory 211 of the portable terminal device 110, and the group conditions which are the extraction location 902 and the state 903 correspond. (Condition matching judgment means). The condition match determination means may be provided in the mobile terminal device 110 or the mail receiving server 100.

  Then, the CPU 201 of the mobile terminal device 110 obtains the character string condition having the highest priority among the character strings and groups that match the conditions, the character string that matches the group conditions, and the position information 607 specified from the group as the distance. The calculation means selects and specifies the first position information (representative evaluation information) used for calculating the distance information (step S1310 / third position information specifying means). The third position information specifying unit may be provided in the mail receiving server 100.

  Further, for example, when the position of the mobile terminal apparatus 110 moves and the distance between the first position information and the second position information changes, the CPU 201 of the mobile terminal apparatus 110 moves the movement distance. And sorts the e-mails in the order of the moving distance and determines to control to display on the display screen (step S1405 / moving distance calculating means, determining means of claim 11). The moving distance calculation means and the determination means of claim 11 may be provided in the mail receiving server 100.

  In this case, for example, the distances of the first position information and the second position information are closer to each other, and the movement distances are sorted in descending order (deciding means according to claim 12). By doing so, it is possible to preferentially display an e-mail having information on the position where the user having the mobile terminal device 110 is approaching on the display screen.

  Further, the CPU 201 of the mail receiving server 100 specifies time information from the electronic mail (first time information specifying means). For example, time information indicating the start time of “meeting” described in the electronic mail is specified. Then, the CPU 201 of the mail receiving server 100 acquires the current time (second time information specifying means), determines whether the meeting start time is a time after the current time, and the meeting start time is a time after the current time. If it is, the e-mail of the identification source of the start time of the meeting is determined as the mail to be displayed on the display screen with priority over other mails (Determination means according to claims 8 and 11).

  Note that the first time information specifying means, the second time information specifying means, and the determining means according to claims 8 and 11 may be provided in the mobile terminal device 110.

  In this case, the display priority order of the e-mail is stored in a time priority table that is a display priority table based on time information stored in the external memory 211 of the mail receiving server 100 to the portable terminal device 110 or the like. (Time order priority storage means).

  The CPU 201 of the mobile terminal device 110 calculates the difference time between the first time information and the second time information (time difference calculation means), and is the time that is the difference time set in the time priority table. The match determination is performed with reference to the combination of the condition and the priority order corresponding to the time condition (display condition match determination means). Note that the display condition match determination means may be provided in the mail receiving server 100.

  Then, the e-mail corresponding to the first time information, which is the identification source of the time difference that matches the condition, is determined as an e-mail preferentially displayed with respect to other mails. .

  By performing all of the processing and means described above with the mobile terminal device 110, the present invention can be realized with the mobile terminal device 110 alone, without the processing of the mail receiving server 100.

  Further, the mail receiving server 100 performs all the processes in FIGS. 1 to 13 in the present invention and the processes other than the display process in step S1409 in FIG. It is possible to limit only the display priority of the e-mail determined in step 1 and the display execution process according to the priority.
