In addition, the telephone number 1 is a telephone number for a mobile phone terminal of a communication partner, and the telephone number 2 is a telephone number of a communication partner, for example, home or work.

  The attribute information is attribute information related to the user of the mobile phone terminal of the communication partner. Similar to the attribute information of the user address data described with reference to FIG. , In addition to information about "what you want", information about "what you care about", information about "what you don't like", date of birth, blood type, etc. It consists of various information about the person.

  As shown in FIG. 3, each piece of information about the communication destination of the general address data shown in FIG. 3 includes, for example, the infrared transmission / reception unit 113, the wireless LAN communication antenna 111 and the wireless LAN communication control unit 112, and the built-in When mail addresses are exchanged through communication means such as the antenna 101 and the communication circuit 102, information from another device is received, and in the form shown in FIG. It can be stored in.

  In addition, the general address data shown in FIG. 3 can be provided and stored from other devices when exchanging mail addresses, but can be registered or modified by the user through the operation unit 106. And can be deleted.

  It should be noted that the address data supplied from the communication partner is not necessarily provided with all the information shown in FIG. 3, but only the name, e-mail address, and attribute information are provided. In some cases, only the information provided is provided. In such a case, the storage area of the data that was not provided is initialized (initialized), and no data exists.

  As can be seen from the description of the user address data shown in FIG. 2 and the general address data shown in FIG. 3, the mobile phone terminal 100 of this embodiment is able to exchange the name and mail address in exchange of address data. In addition, various attribute information related to the user, which has not been handled in the conventional mobile phone terminal, can be exchanged with each other.

  In other words, when exchanging e-mail addresses, in addition to your name and e-mail address, you also provide self-related attribute information (attribute information about the user) to the other party. In addition, attribute information related to the user is also provided, each of which is stored and held so that it can be used.

  As shown in FIG. 3, the received communication partner attribute information is stored and held as one piece of data constituting the general address data, so that the “favorite” in the friendship relationship of the self is obtained. Various information can be obtained by analyzing the attribute information such as the tendency and the tendency of “desirable things”.

[Content data metadata]
FIG. 4 is a diagram for explaining metadata added to various content data stored and held in the nonvolatile memory of the memory unit 105 of the mobile phone terminal 100 of this embodiment.

  The cellular phone terminal 100 according to this embodiment can acquire various content data through several paths, store it in the nonvolatile memory of the memory unit 105, and read and use it as necessary. It is.

  That is, the cellular phone terminal 100 of this embodiment is connected to the Internet via the communication circuit 102 and the antenna 101, and acquires various content data such as image data, text data, and music data from the target server device. This can be stored in the nonvolatile memory of the memory unit 105.

  In addition, various content data such as image data, text data, and music data is acquired from a device such as a personal computer on an unrelated LAN through the wireless LAN antenna 111 and the wireless LAN communication control unit 112, and is stored in the nonvolatile memory of the memory unit 105. Can be stored in memory.

  In addition, by photographing a subject through the camera unit 118, image data of the subject can be captured and stored in the nonvolatile memory of the memory unit 105. Also, an e-mail addressed to the own device received through the Internet or an e-mail transmitted from the own device input through the operation unit 106 can be stored in the nonvolatile memory of the memory unit 105.

  Although not shown, the mobile phone terminal according to this embodiment includes, for example, an input / output terminal of a digital interface, receives content data from an external device through the digital interface, and stores the content data in the memory unit 105. It is stored and held in a non-volatile memory, and can be read and used as needed, as with other content data.

  As described above, the cellular phone terminal 100 according to this embodiment can use various data captured as content data through the Internet, LAN, camera unit 118, operation unit 106, digital interface, and the like. In the cellular phone terminal 100 according to this embodiment, as shown in FIG. 4, the title, acquisition date (shooting date), keyword, and the like are stored in the various content data captured and stored in the own device. Various metadata such as can be added.

  Here, the title is a title (title) for the content data, and is text data. The acquisition date (shooting date) is date information indicating the date when the content data was acquired. If the content data is acquired data image data through the camera unit 118, it is date information indicating the date of shooting. . Here, the acquisition date (shooting date) is the date information, but the day of the week information and the time information may be included.

  The keyword is text data that can be arbitrarily input by the user through the operation unit 106. For example, information such as “delicious cake” and “delicious shop”, “favorite things” such as bags and jewelry, and “desired things”. The general name and name of the product, the company name of the manufacturer or distributor of the target product, the name of the store that sells the target product, the name of the creator of the content data or the name of the person concerned, etc. A plurality of various attribute information about data can be set.

  Such metadata is added to a predetermined area of the file in which the content data is stored, or is associated with a file name or the like, and only the metadata is managed separately from the content data. To be able to do so.

  Also, the metadata shown in FIG. 4 is an example. For example, when image data is obtained by photographing a subject through the camera unit 118, the image data is obtained through a clock circuit (not shown). Along with the date and time information, position information indicating the shooting position acquired through the GPS receiving antenna 116 and the GPS unit 117 may be added as metadata.

[Ontology dictionary]
5-7 is a figure for demonstrating the ontology dictionary mounted in the mobile telephone terminal 100 of this Embodiment. The term “ontology” originally means ontology, but in recent years, technology to structure the knowledge system that people have unconsciously formed in their heads, sharing knowledge with others , It is used as a word to indicate a technology that is attracting attention as a technology for facilitating fusion.

  In other words, ontology is a technical method for defining simple definition semantic information. By using ontology, knowledge can be shared using semantic connections. A dictionary formed using this ontology is called an ontology dictionary.

  FIG. 5 is a diagram for explaining a UML (Unified Modeling Language) class diagram used for describing an ontology dictionary. In the case of an ontology dictionary, a description method such as UML is used to define a semantic connection between words. As shown in FIG. 5, in the case of UML, three model elements, ie, class, association (generalization), and association (aggregation) are prepared.

  A class originally means a group of similar things, but in this example, it corresponds to each word (word). That is, the class name of each class corresponds to a word (word) constituting the ontology dictionary, and an attribute name can be added to each class (each word).

  The relationship (generalization) represents a generalization / specialization relationship between classes, and is described so as to connect classes with so-called triangular arrows as shown in the middle of FIG. is there. Then, as shown in the middle of FIG. 5, when class A and class B are connected by association (generalization) so that a triangle is located on the class B side, class A is class B It is shown that they are in a subset relationship. That is, as shown in the middle part of FIG. 5, when class A and class B are connected by association (generalization), class A is included in class B. For implementation, class A is class The features of B will be inherited and expanded.

  The relationship (aggregation) represents an aggregation relationship between classes, and is described so as to connect classes with so-called square arrows (diamond arrows) as shown in the lower part of FIG. As shown in the lower part of FIG. 5, when class A and class B are connected by association (aggregation) so that a square (diamond) is located on the class B side, class A is It is shown that the aggregate is class B.

  An example of the ontology dictionary described using the UML described with reference to FIG. 5 is shown in FIG. FIG. 6 shows a part of an ontology dictionary for “food” described using UML. As shown in FIG. 6, the ontology dictionary in this example includes words “words” such as “tiramisu”, “cream cheesecake”, “cheesecake”, “dessert”, “main dish”, “cooking”, and “food”. ) As a class.

  As shown in FIG. 6, as indicated by “+ taste (taste)”, for example, attributes about tastes such as “delicious” and “bad” can be added to each class, and as necessary. Accordingly, as indicated by “+ type”, an attribute about the type can also be added.

  And as shown in FIG. 6, “tiramisu (class C11)” and “cream cheesecake (class C12)” are generalized (is−) between “cheesecake (class C21)”. “Cheesecake (Class C21)” has a generalization relationship (is-a relationship) with “Desert (Class C31)”, and “Cooking (Class C41)” (Class C51) ”has a generalization relationship (is-a relationship), and“ dessert (class C31) ”and“ main dish (class C32) ”are between“ dish (class C41) ” It is shown that there is an aggregation relationship (part of relationship).

  In other words, in the ontology dictionary shown in FIG. 6, “tiramisu (class C11)” and “cream cheesecake (class C12)” belong to “cheesecake (class C21)” and “cheesecake (class C21)”. “C21)” belongs to “dessert (class C31)”, “dish (class C41)” belongs to “food (class C51)”, “dessert (class C31)” and “main dish (class C32)”. Clearly indicates that there is a series of relationships that are aggregated in “dish (class C41)”.

  FIG. 7 is a diagram illustrating a hierarchical relationship of words (words) related to “food” to which an attribute (attribute value) “delicious” is added based on the ontology dictionary of “food” illustrated in FIG. 6. In the ontology dictionary for “food” shown in FIG. 6, the attribute “delicious” is added to each of the five words “food”, “cooking”, “dessert”, “main dish”, and “cream cheesecake”. It is assumed that

  The hierarchical relationship of the words in the ontology dictionary shown in FIG. 6 is as follows. As shown in FIG. 7, the first hierarchy is “food”, the second hierarchy is “dish”, and the third hierarchy is “dessert”. The “main dish”, the fourth level is “cheese cake”, and the fifth level is “tiramisu” and “cream cheesecake”.

  As described with reference to FIGS. 6 and 7, the ontology dictionary does not simply store words (words), but the words are associated with each other. For this reason, by having the ontology dictionary described with reference to FIGS. 6 and 7 in both the own device and the communication partner, information exchange about “food” can be smoothly performed. Sharing and integration of knowledge and information can be facilitated.

  As described above, the cellular phone terminal 100 according to this embodiment includes the user address data described with reference to FIG. 2, the general address data described with reference to FIG. 3, and the ontology dictionary described with reference to FIGS. In addition, as described with reference to FIG. 4, metadata can be added to various content data stored and held in its own device.

  In the case of the mobile phone terminal 100 of this embodiment, for example, at the time of address exchange, attribute information registered as user address data can be exchanged in addition to a name and an e-mail address. The In other words, the name, e-mail address, and attribute information can be transmitted from the own device and provided to the other party, and transmitted from the other party communication terminal having the same configuration as the mobile phone terminal 100 of this embodiment. The incoming name, e-mail address, and attribute information are received and can be additionally recorded in the general address data shown in FIG.

  Therefore, each time the address exchange is performed, the mobile phone terminal 100 according to this embodiment provides attribute information, which is information about the user of the communication terminal of the other party, in addition to the name and e-mail address of the other party. In response to this, as shown in FIG. 3, in addition to name, e-mail address, etc., attribute information can also be collected and stored.

  Then, the cellular phone terminal 100 according to this embodiment uses the metadata added to the content data stored and held in its own device, or when the content data is text data such as e-mail data. The title and text data body are also analyzed using the ontology dictionary installed in the device, and the content data is classified based on the appearing words (words).

  From the content data classified as described above, content data having the same metadata and word as the high rating attribute information is searched and extracted from the attribute information included in the general address data described with reference to FIG. In addition, systematic output of relevant content data can be realized according to the collected attribute information.

[Specific example of systematically outputting content data]
FIG. 8 also shows that attribute information is exchanged by exchanging address data between the mobile phone terminal 100A and the mobile phone terminal 100B, and the collected attribute information is obtained in each of the mobile phone terminal 100A and the mobile phone terminal 100B. By using information, metadata such as metadata added to content data, and ontology dictionaries, the content data stored in the device can be organized without bothering the user (user). It is a processing flow for demonstrating an example of the process in the case of outputting.

  Here, each of the mobile phone terminal 100A and the mobile phone terminal 100B has the configuration shown in FIG. 1, and the nonvolatile memory of the memory 105 stores the user address data shown in FIG. General address data, content data to which metadata as shown in FIG. 4 is added, and ontology dictionary described with reference to FIGS. 5 to 7 are stored and held.

  As described with reference to FIG. 1, each of the mobile phone terminal 100A and the mobile phone terminal 100B includes a system connected to a wide area network through the built-in antenna 101 and the communication circuit 102, a wireless LAN communication antenna 111, and a wireless LAN communication. A system that connects to a wireless LAN through the control unit 112 and a system that communicates one-to-one with infrared through the infrared transmission / reception unit 113 are provided. In the example shown in FIG. 8, a case where address exchange is performed by performing communication in the ad hoc mode through the wireless LAN communication antenna 111 and the wireless LAN communication control unit 112 will be described as an example.

  As shown in FIG. 8, the mobile phone terminal 100A includes an ontology dictionary AJ, user address data A1, and general address data A3. The mobile phone terminal 100B includes an ontology dictionary BJ, user address data B1, and general address data B3. The ontology dictionaries AJ and BJ are configured as described with reference to FIGS.

  Further, the user address data A1 and B1 are formed as described with reference to FIG. Further, the general address data is composed of a name, an address, mail addresses 1 and 2, telephone numbers 1 and 2, and attribute information as described with reference to FIG. However, here, in order to simplify the explanation, each of the general address data A3 and B3 will be described as having at least names, e-mail addresses, and attribute information for a plurality of communication destinations as communication destinations.

  In the case of the example shown in FIG. 8, the user of the mobile phone terminal 100A performs a predetermined operation for exchanging addresses, so that the mobile phone terminal 100A performs an ad hoc mode on the mobile phone terminal 100B. When a request to perform one-to-one communication is transmitted and a response is returned from the mobile phone terminal 100B, a communication line is connected and communication in a one-to-one ad hoc mode (ad hoc communication) ) Is started (step S1).

  Specifically, when a predetermined operation for exchanging addresses is accepted, the control unit 108 of the mobile phone terminal 100A controls the wireless LAN communication control unit 112, and the wireless LAN communication control unit 112, wireless LAN A request to perform one-to-one communication in the ad hoc mode is transmitted through the communication antenna 111.

  In the mobile phone terminal 100B that has received this, the control unit 108 of the mobile phone terminal 100B controls the wireless LAN communication control unit 112 by performing a predetermined operation to which the user of the mobile phone terminal 100B responds. Then, by returning a response through the wireless LAN communication control unit 112 and the wireless LAN communication antenna 111, a communication line is connected on the wireless LAN between the mobile phone terminal 100A and the mobile phone terminal 100B, and in the ad hoc mode. Communication can be performed one-to-one.

  Then, the mobile phone terminal 100A forms exchange data A2 based on the user address data A1 of its own device, and transmits it to the mobile phone terminal 100B that is the communication partner (step S2). The exchange data A2 is formed from the user address data described with reference to FIG. 2, but the data to be exchanged can be limited in advance.

  That is, for each data constituting the user address data, the security level can be set, and the user can set in advance the data that can be provided and the data that is not provided. In particular, with respect to attribute information, what can be provided and what cannot be provided can be specified in detail. In the example shown in FIG. 8, the exchange data A2 transmitted from the mobile phone terminal 100A to the mobile phone terminal 100B includes a name, a mail address, and attribute information.

  Then, the mobile phone terminal 100B receiving the exchange data A2 from the mobile phone terminal 100A receives the exchange data A2 from the mobile phone terminal 100A and adds this to the general address data B3 of the own device. In FIG. 8, the data of the hatched portion at the end of the general address data B3 of the mobile phone terminal 100B is information corresponding to the exchange data A2 from the mobile phone terminal 100A.

  Correspondingly, the mobile phone terminal 100B forms exchange data B2 based on the user address data B1 of its own device, and transmits it to the mobile phone terminal 100A that is the communication partner (step S3). . Even in the mobile phone terminal 100B, the exchange data B2 is formed from the user address data described with reference to FIG. 2, but in the mobile phone terminal 100A, the exchange data A2 is formed from the user address data. Similarly, the data to be exchanged can be limited in advance.

  That is, in the example shown in FIG. 8, the exchange data B2 transmitted from the mobile phone terminal 100B to the mobile phone terminal 100A is composed of a name, a mail address, and attribute information. Then, the mobile phone terminal 100A that receives the exchange data B2 from the mobile phone terminal 100B receives the exchange data B2 from the mobile phone terminal 100B and adds it to the general address data A3 of the own device. In FIG. 8, the data in the hatched portion at the end of the general address data A3 of the mobile phone terminal 100A is information corresponding to the exchange data B2 from the mobile phone terminal 100B.

  Thus, after the mobile phone terminal 100A and the mobile phone terminal 100B exchange addresses with each other, the communication line on the connected wireless LAN is released, and communication in a one-to-one ad hoc mode (ad hoc communication) Is finished (step S4).

  Thereafter, the cellular phone terminal 100A performs an attribute determination process for the stored content data based on the ontology dictionary and the attribute information of the general address data (step T1). Specifically, the control unit 108 of the mobile phone terminal 100A is included in the metadata of the image content data, the title of the e-mail, and the text stored in the own device based on the ontology dictionary dictionary AJ of the own device. Performs keyword parsing and classification, and searches and extracts content data with high rating attribute information added or included in general address data registered on the device itself .

  Then, the control unit 108 of the mobile phone terminal 100A automatically selects content data to which high rating attribute information is added or included based on the result of step T1, and based on the ontology dictionary. Then, systematically output the content data (step T2).

  In this step T2, for example, in the nonvolatile memory of the memory unit 105 of the mobile phone terminal 100A, as shown in the content data group A4 in FIG. 8, the content data includes image c, image d, image e, image f, Mail g, mail h, and mail i are stored and held. Of these, image e, image f, mail g, mail h, and mail i have information a added or included as attribute information. In this case, the image e, image f, mail g, mail h, and mail i are selected as content data to be output, and are systematically output based on the ontology dictionary. In the mobile phone terminal 100A of this example, the information is displayed on the display unit 107.

  On the other hand, in the cellular phone terminal 100B, similarly to the case of step T1 in the cellular phone terminal 100A, the attribute determination process for the stored content data is performed based on the ontology dictionary and the attribute information of the general address data. Perform (step T3).

  Then, based on the result of step T3, the control unit 108 of the mobile phone terminal 100B automatically selects content data to which high rating attribute information is added or included, and based on the ontology dictionary. Then, systematically output the content data (step T4).

  In step T4, for example, in the nonvolatile memory of the memory unit 105 of the mobile phone terminal 100B, as shown in the content data group B4 in FIG. 8, the content data includes image c, image d, image l, image m, Mail n, mail o, and mail p are stored and held. Among these, image l, image m, mail n, mail o, and mail p have information b added or included as attribute information. In this case, the image l, the image m, the mail n, the mail o, and the mail p are selected as output target content data, and are systematically output based on the ontology dictionary. In the mobile phone terminal 100B of this example, the information is displayed on the display unit 107.

  As described above, in each of the mobile phone terminal 100A and the mobile phone terminal 100B in this example, various attributes acquired from the other party of communication without a troublesome effort such as the user classifying the content data in advance. Based on the information, the ontology dictionary, and the information about the content such as the metadata added to the content data and the text data that constitutes the content data, the content data is classified and organized, and the content data to be output is specified. This is systematically output.

  As described above, it is possible to set a security level for each data constituting user address data, in particular, attribute information. When exchanging data other than a dictionary, a preset security level is set. It is possible to control whether or not data exchange is possible. In addition, for mobile phone terminals that do not have an ontology dictionary, it is possible to provide an ontology dictionary held by the device itself, or to exchange an ontology dictionary between mobile phone terminals. It is.

  Further, in the above-described embodiment, the description has been made assuming that communication is performed in the ad hoc mode. However, in addition to so-called ad hoc communication, even when using a network such as a WLAN, the exchange data is pre- It is possible to exchange according to the set security level.

  Further, in the description of step T1 in FIG. 8, based on the ontology dictionary dictionary of the own device, the metadata of the image content data stored in the own device, the title of the e-mail, and the keyword analysis included in the text are analyzed. In the general address data registered on the device, the content data with high rating attribute information added or included is described as being searched and extracted. However, it is not limited to this.

  In addition to extracting content data having high rating attribute information in general address data, the content data having high rating attribute information is searched for classified content data regardless of the attribute information of general address data. May be extracted.

  In the case of the above-described example, content data including high rating attribute information in general address data is extracted, or content data having high rating attribute information is extracted regardless of general address data. Although the case has been described, the present invention is not limited to this. For example, content data including attribute information designated by the user can be extracted and systematically output based on an ontology dictionary.

  In addition, systematic output of content data based on ontology dictionary is to perform hierarchical output (hierarchy display) according to is-a relationship (generalization / specialization relationship) and part of relationship (aggregation relationship). Is also possible.

[Specific examples of systematic output of content data]
Next, a specific example of systematic output (display) of content data in the case of the mobile phone terminal 100A described with reference to FIG. 8 will be described more specifically with reference to FIGS.

  FIG. 9 is a diagram for explaining attribute information stored in the general address data of the mobile phone terminal 100A. In FIG. 8, as shown in the general address data A3, the general address data stored and held in the mobile phone terminal 100A is for three persons, Mr. C, Mr. D, and Mr. B. The address data for Mr. B is provided from the mobile phone terminal 100B owned by Mr. B in the process of step S3 and is collected the latest.

  Originally, the so-called address book that stores general address data is capable of storing and managing information on the other party with whom communication is possible in units of several hundred people. For the sake of simplicity, it is assumed that data of three people, Mr. C, Mr. D, and Mr. B, are stored and held.

  In the case of the general address data A3 in FIG. 8, the attribute information of Mr. C is “b”, but the attribute information of Mr. D and Mr. B is “a”. Of course, the attribute information is not limited to one, and there may be a plurality of pieces of attribute information. More specifically, the attribute information “b” and “a” are information indicating “favorites”, and the attribute information “a” is attribute information “cream cheesecake”. The information “b” is attribute information “ramen”.

  This state can be summarized as shown in FIG. 9A. In the case of this example, as is clear from FIG. 9A, since the attribute information of Mr. D and Mr. B other than Mr. C is “Cream cheesecake”, the attribute information of high rating (in this example) As shown in FIG. 9B, the attribute information having a high appearance frequency is “cream cheesecake”.

  In FIG. 8, as can be seen from the exchange data A2 formed from the user address data A1 of Mr. A who is the user of the mobile phone terminal 100A, the attribute information of the user A of the mobile phone terminal 100A is also shown. Also, “a”, that is, “cream cheesecake”. For this reason, as will be described below, content data stored in the nonvolatile memory of the memory unit 105 of the mobile phone terminal 100A includes content data to which attribute information “cream cheesecake” is added. To do.

  FIG. 10 is a diagram for explaining the content data stored in the nonvolatile memory of the memory unit 105 of the mobile phone terminal 100A shown in FIG. As shown in FIG. 10, a plurality of image content data PT1, PT2, PT3,... And a plurality of e-mail data ML1, ML2, ML3,. .

  Here, each of the image content data PT1, PT2, PT3,... Is acquired through the Internet or wireless LAN, acquired by photographing through the camera unit 118, or through the infrared transmission / reception unit 113, as described above. It is acquired. Further, each of the e-mail data ML1, ML2, ML3,... Is addressed to the own device received through the Internet as described above.

  In FIG. 10, the image content data PT1 is about a sweater (clothing), and is added with two metadata of “autumn / winter” and “sweater”. Each of the image content data PT1, PT2, and PT3 relates to a cream cheese cake, and two metadata, “delicious” and “cream cheese cake”, are added.

  The image content data PT5 is for a ring, and is added with two metadata “diamond” and “ring”. The image content data PT6 is for a pendant, and is added with two metadata, “diamond” and “pendant”.

  Here, although it has been described that two pieces of metadata are added to each image content data, the present invention is not limited to this. One or more arbitrary numbers of metadata can be added. In addition to the above keywords, the contents can include various information such as acquisition date / time, acquisition position, URL (Uniform Resource Locators), etc. as metadata. Information such as explanatory text (text data) can also be added.

  In FIG. 10, e-mail data ML <b> 1 is information regarding cream cheesecake, and includes the word “cream cheesecake” in the text. The e-mail data ML2 informs that a new sweater has been purchased, the e-mail data ML3 informs that the e-mail address has been changed, and the e-mail data ML4 informs of a schedule change. Is. That is, the e-mail data ML1 includes a word (word) “cream cheesecake” which is high rating attribute information in the general address data.

  Then, the control unit 108 of the mobile phone terminal 100A, for example, based on the ontology dictionary formed as shown in FIG. 7, the title of the e-mail data that is metadata or text data added to the content data Parse and classify text and body text. More specifically, the control unit 108 performs syntax analysis on the title and the main part of the metadata and e-mail data to identify words (words), and the ontology dictionary formed as shown in FIG. And classifying the content data having high rating metadata and words (words) so as to be positioned higher.

  Thereafter, the control unit 108 extracts content data including high rating attribute information as metadata or words (words) in the attribute information of the general address data based on the classification result, as shown in FIG. 9B. This is output (displayed) according to the ontology dictionary.

  FIG. 11 is a diagram for explaining an example in which content data including high rating attribute information in general address data as metadata or words (words) is displayed preferentially. That is, as shown in FIG. 9B, the attribute information of the general address data of the mobile phone terminal 100A is “cream cheesecake”, so that the content data shown in FIG. By performing analysis, classification processing, and extraction processing, image content data PT2, PT3, PT4 and e-mail data ML1 are extracted, and these are preferentially based on the ontology dictionary shown in FIG. , The word “cream cheesecake” is finally assigned to the component of the folder FL1 called “food”.

  As a result, as shown in FIG. 11, when the “food” folder FL1 is opened (opened), the image content data PT2, PT3, PT4, and e-mail data assigned as components of the “food” folder FL1. ML1 is displayed so that it can be selected. When one of the image content data PT2, PT3, and PT4 is selected in the state shown in FIG. 11, for example, the enlarged image and detailed information can be displayed on the display unit 107. The Further, when the e-mail data ML1 is selected, the body data can be displayed on the display unit 107.

  As described above, the user of the mobile phone terminal 100A simply attaches metadata to the image content data stored in the device so that the image content data can be analyzed and classified. For text data such as e-mail data, etc., syntactic analysis and classification processing according to the ontology dictionary is performed, and attribute information collected at the time of address exchange is taken into consideration, among attribute information collected as general address data, Content data having high-rating attribute information as metadata or words (words) is extracted, and can be displayed with priority based on an ontology dictionary.

  In the case of this example, the finally extracted content data is stored in the top “food” folder. Therefore, as described with reference to FIG. 11, for example, even if the folder “Cream Cheesecake” is not opened, only the folder “Food” is opened, and extraction is performed according to the high rating attribute information of the general address data. Content data with the word “cream cheesecake” and content data can be systematically output, so that information can be used in preference to other content data. Be made possible.

  In addition, content data having metadata and words (words) corresponding to high rating attribute information in the attribute information of general address data collected at the time of address exchange is preferentially extracted. Content data can be systematically output in accordance with attribute information according to the friendship of the user. As a result, the content data that the user may need can be preferentially provided.

  Further, hierarchical display can be performed based on the ontology dictionary shown in FIG. FIGS. 12 and 13 are diagrams for explaining an example in which hierarchical display is performed according to the ontology dictionary. That is, according to the ontology dictionary shown in FIG. 7, as shown in FIG. 12, a food folder FL1, a cooking folder FL2, a main dish folder FL3, a dessert folder FL4, a cheesecake folder FL5, a cream cheesecake, Folder FL6 and tiramisu folder FL7 can be formed.

  Even in this example, based on the ontology dictionary formed as shown in FIG. 7, the title and body of the e-mail data, which is metadata and text data added to the content data, are Analyze and classify. Thereafter, based on the classification result, content data including high rating attribute information as metadata or words (words) is extracted from the attribute information of the general address data, and the target folder is extracted according to the ontology dictionary. Assign to.

  Specifically, when the state of the attribute information for the general address data of the mobile phone terminal 100A is in the state shown in FIG. 9 and the content data is in the state shown in FIG. 10, the image content data PT2, PT3, PT4, Since the e-mail data ML1 has “cream cheesecake”, which is high rating attribute information, as metadata and words (words), these are extracted, and in this example, the cream cheesecake The folder FL6 is assigned.

  Then, as shown in FIG. 12A, the food folder FL2 can be accessed by opening the food folder FL1, and the main dish folder FL3 and the dessert folder FL4 can be accessed by opening the food folder FL2. When the dessert folder FL4 is opened, the cheesecake folder FL5 can be accessed, and when the cheesecake folder FL5 is opened, the cream cheesecake folder FL6 and the tiramisu folder FL7 can be accessed.

  When the cream cheesecake folder FL6 is opened at this time, as shown in FIG. 13, the image content data PT2, PT3, PT4, and e-mail data extracted as described above and assigned to the cream cheesecake folder FL6 are displayed. It is made possible to access ML1.

  In this case, since the hierarchy display based on the ontology dictionary shown in FIG. 7 can be performed, the analysis is performed based on the ontology dictionary as described above by tracing the folder hierarchy according to the ontology dictionary. Thus, it is possible to use the content data which is classified and extracted as including high rating attribute information of general address data as metadata or words (words).

  Here, in order to simplify the explanation, the attribute information of the general address data is used. However, the present invention is not limited to this. Of course, not only attribute information of general address data but also attribute information of user address data may be included.

[Other examples of ontology dictionaries and how content data is displayed]
Next, another example of the ontology dictionary will be described, and a display mode of content data using the ontology dictionary will be described.

  14 and 15 are diagrams for explaining another example of the ontology dictionary. As shown in FIGS. 14 and 15, the ontology dictionary of this example is composed of eight layers from the first layer to the eighth layer. FIG. 14 shows the first layer to the fifth layer, and FIG. Shows from the fifth layer to the eighth layer. That is, FIG. 14 and FIG. 15 describe the fifth hierarchy in an overlapping manner.

  As shown in FIG. 14, the ontology dictionary of this example has items such as “Society”, “Culture”, “Hobby”, “Practical”, “Science”, “Politics”, “Life” as the first hierarchy. When the item “Society” of the large category is selected, the second hierarchy (small category (small category)) consisting of the item “brand product” is included. Yes.

  In FIG. 14, the item constituting the small category of the second hierarchy is only “brand product”. However, the present invention is not limited to this, and as will be described later, the contents of the ontology dictionary can be increased by adding items constituting a small category. For example, various items such as “no brand product” and “shop (store)” can be added to the second hierarchy.

  When the “brand product” at the second level is selected, the third level (the level of the production area) including the items “France”, “America”, and “Italy” is provided. When the item “France” in the third layer is selected, the fourth layer (store name (brand name) layer) including items “VVVVV” and “EEEEEE” is provided.

  Similarly, when the item “America” in the third hierarchy is selected, the fourth hierarchy (store name (brand name) hierarchy) consisting of items such as “CCCCCC” is provided, and when the item “Italy” in the third hierarchy is selected. , “FFFFF” has a fourth hierarchy (store name (brand name) hierarchy).

  And if you select the brand name “VVVVV” which is the item of the 4th hierarchy, for women (women), “city bag”, “luggage”, “pochette & clutch”, “wallet & leather goods (accessories)”, In addition to items such as “Diary”, “Shoes”, “Jewelry”, etc., there is a fifth hierarchy (product genre hierarchy) that is not shown in detail but also has items for men. Yes. Similarly, when the brand name “EEEEEE”, which is an item in the fourth hierarchy, is selected, the fifth hierarchy (product genre hierarchy) having each item for ladies and each item for men is provided.

  Next, as shown in FIG. 15, when the item “city bag” in the fifth hierarchy (product genre hierarchy) for the brand name “VVVVV” is selected, “normal pattern type”, “normal pattern type / denim”, “ The sixth hierarchy (product category hierarchy) having items such as “normal pattern type / multicolor”, “normal pattern type / VVX”, “normal pattern type / suede”, “composite pattern type”,... .

  Then, when the item “regular pattern type / denim” in the sixth layer (product category layer) is selected, the seventh layer (product) having items such as “Mini XXX”, “GGGG”, “PPPP”,... Name hierarchy). When the item “Mini ○○○○” of the seventh hierarchy (product name hierarchy) is selected, the eighth hierarchy (product attribute (color) hierarchy) including items such as “blue” and “pink” is provided. The

  When the item “normal pattern type / multicolor” in the sixth hierarchy (product category hierarchy) is selected, the seventh hierarchy (product name hierarchy) having items such as “XX”, “YYYYY”, “ZZZZZ”,... Is made to have. When the item “XX” in the seventh hierarchy (product name hierarchy) is selected, the eighth hierarchy (product attribute (color) hierarchy) including items such as “blue” and “pink” is provided.

  Similarly, as shown in FIG. 15, when the item “city bag” in the fifth hierarchy (product genre hierarchy) for the brand name “EEEEEE” is selected, “AA”, “BB”, “CC”, “DD” ,... Are included in the sixth hierarchy (product category hierarchy).

  When the item “AA” in the sixth hierarchy (product category hierarchy) is selected, the seventh hierarchy (product name hierarchy) having items such as “AA-1”, “AA-2”,... The When the item “AA-1” in the seventh hierarchy (product name hierarchy) is selected, the eighth hierarchy (product attribute (color) hierarchy) including items such as “gray” and “beige” is provided.

  As described above, the ontology dictionary in this example is composed of eight layers, and is downloaded through the Internet, acquired from an external device through a wireless LAN, or provided by another mobile phone terminal. Be able to get. After the ontology dictionary is acquired, for example, “like”, “dislike”, “desire”, “not want”, “cheap” for each item (word (word)) constituting the ontology dictionary. , Attribute information such as “high” can be added.

  Also, based on the ontology dictionary, when the metadata or content data added to the content data includes text data, the title and the main part are analyzed and classified based on the ontology dictionary, and specific attribute information is obtained. It is possible to acquire and hold summary information of content data possessed.

  In addition, after acquiring the ontology dictionary, in the case of the missing branch, for example, the ontology dictionary shown in FIGS. 14 and 15, the product genre, product category, brand name “CCCCC” and brand name “FFFFF” The product name, product attribute, etc. can be acquired and added.

  Therefore, by adding attribute information or adding missing branches to the ontology dictionary, the ontology dictionary that is installed in the device is customized, and each user's mobile phone terminal is customized. It is also possible to make it a customized dictionary unique to.

  Next, a specific mode in the case of outputting (displaying) content data in the mobile phone terminal 100 of this embodiment that stores and holds the ontology dictionary described with reference to FIGS. 14 and 15 will be described. In the case of the example described with reference to FIG. 8, the content data stored in the own device is systematically output using the attribute information received and collected at the time of address exchange or the like. I made it. However, in the case of the example described below, a case will be described in which content data stored in the own device is systematically output using attribute information set by the user for user address data.

  FIG. 16 is a list of attribute information in the user address data stored and held in the portable information terminal 100 of this embodiment. As shown in FIG. 16, in the user address data stored in the nonvolatile memory of the memory unit 105 of the mobile phone terminal 100, there are three types of “sex”, “favorite”, and “desirable”. The attribute information is registered.

  Then, as shown in FIG. 16, the sex is “female”, the “favorite” is “XX-chan (model)”, “VVVVV (brand name)”, “regular pattern type denim”, “bag”. , “Pink” and “Jewelry”, and what you want is registered as “Cheap brand goods” and “Normal pattern type / multicolor”.

  In FIG. 17, in this example, the control unit 108 of the mobile phone terminal 100 that has received an operation for displaying content data using the ontology dictionary through the operation unit 106 is displayed on the display screen 107 of the mobile phone terminal 100. It is a figure for demonstrating the display image displayed initially.

  As shown in FIG. 17, the uppermost portion 107T of the display screen 107 has an electric field strength icon for notifying the reception electric field strength of the transmission signal from the base station, and an e-mail icon for instructing execution of the e-mail function. In addition, a battery remaining amount icon indicating the remaining amount of battery and a current time display are displayed.

  As shown in FIG. 17, a function unit 71, a MENU (menu) unit 72, a selection unit 73, an opening unit 74, and a display switching unit 75 are provided as guidance information at the bottom of the display screen 107. Yes. Each of the operation keys provided on the operation unit 106 can be operated by operating an operation key corresponding to the function unit 71, and an operation corresponding to the MENU unit 72. The menu can be displayed by operating the keys.

  Further, by operating the operation keys corresponding to each triangle mark of the selection unit 73, the cursor can be moved to select an item, and by operating the operation keys corresponding to the opening unit 74, The selected folder or file can be opened to display target information, and the display on the display unit 107 can be switched by operating an operation key corresponding to the display switching unit 75. Will be able to.

  Then, as described above, the control unit 108 of the mobile phone terminal 100 that has received the operation for displaying the content data using the ontology dictionary receives the items based on the ontology dictionary shown in FIGS. 14 and 15. Items for the second to third layers where “brand product” is the only component are displayed.

  That is, as shown in FIG. 17, “France”, “America”, and “Italy” exist as the second hierarchy in the “brand products” in the first hierarchy, and “France” exists in the second hierarchy. Indicates that “VVVVV” and “EEEEEE” exist as brand names. In addition, it is indicated that “CCCCC” exists as a brand name in “America” in the second hierarchy, and a brand name “FFFFF” exists in “Italy” in the second hierarchy. .

  Then, the user of the mobile phone terminal 100 operates the operation key of the operation unit 106 corresponding to each triangle of the selection unit 73 to position the cursor SL at the brand name “VVVVV” in FIG. When the operation key corresponding to the operation key 106 is operated to open the folder where the cursor SL is positioned, the control unit 108 of the mobile phone terminal 100 displays as shown in FIG. The display image of the unit 107 is changed.

  FIG. 18 is a diagram for explaining the screen display following FIG. In FIG. 17, when the cursor SL is positioned on the brand name “VVVVV” and the folder corresponding to the brand name “VVVVV” is opened, the control unit 108 displays the brand name “VVVVV” in the fourth hierarchy shown in FIG. "Is positioned at the top and items for three layers from the brand name" VVVVV "are displayed. Specifically, as shown in FIG. 18A, items from the brand name “VVVVV” in the fourth layer to the product category in the sixth layer.

  That is, in the case of the example shown in FIG. 18A, hierarchical display is performed according to the ontology dictionary for the branded product described with reference to FIGS. 14 and 15, but the user of the user shown in FIG. Considering the attribute information, the item corresponding to the attribute information registered as “favorite” or “desirable” of the user of the device is preferentially displayed. That is, in the attribute list shown in FIG. 16, “regular pattern type / denim” is registered as attribute information of a favorite item. In the product category of the sixth hierarchy, “regular pattern type / denim” is registered. It is made to be located at the highest level.

  18A, when the cursor SL is positioned on the “normal pattern type / denim” of the product category and the folder corresponding to the product category “normal pattern type / denim” is opened, The control unit 108 transitions the display screen as shown in FIG. 18B. That is, the product category “ordinary pattern type / denim” in the sixth hierarchy shown in FIG. 15 is positioned at the top, and the ontology dictionary for the brand product shown in FIG. 14 and FIG. Is displayed.

  First, the control unit 108 positions the product category “ordinary pattern type / denim” at the top in accordance with the ontology dictionary for branded products described with reference to FIGS. Items such as “GGGG”, “Mini XXX”, and “Mini XXXX”, which are the product names of the seventh hierarchy to which they belong, are displayed.

  Next, in accordance with the ontology dictionary, the control unit 108, when the metadata or content data added to the content data stored in its own device is text data such as e-mail data, Is analyzed according to each recognized word (word), and the result of this classification process is used to extract and output content data having the product category and product name to be displayed. To do.

  In this case, considering the attribute information of the user address data, the product category and product name corresponding to the attribute information about the user registered in the user address data are included in the metadata, title, and text. Content data is output (displayed) preferentially. Here, the term “priority” means that the data is output more preferentially than the content data that does not have attribute information, such as output to a higher rank or output larger than other content data. .

  In this way, analysis and classification are performed using an ontology dictionary for brand products, so it is possible to extract and display content data having words (words) corresponding to the ontology dictionary in the metadata, Furthermore, it is possible to preferentially output content data that has the same information as the user's attribute information as metadata, or has words (words) in the title or text.

  In the case of FIG. 18B, as described above, the image content data in which the image SN11, the image SN12, and the image SN13 have the display target product category and product name extracted based on the results of analysis and classification as metadata. It is. In this case, the content data corresponding to the user attribute information is preferentially displayed as described above.

  Also, not only image content data but also e-mail data can be output. In the case of the example in FIG. 18B, there is an e-mail notifying that Mina has purchased a product with the product name “Mini XXX” belonging to the product category “Normal pattern type denim”. Is displayed. Then, by selecting the e-mail icon P11, the text of the e-mail can be displayed and read.

  Also, by selecting the icon P12, related information is acquired via a network such as the Internet based on attribute information corresponding to the user's preference registered in the own device and displayed. You can also The related information is, for example, headline information described by RSS (RDF Site Summary / Rich Site Summary / Really Simple Syndication).

  Further, by selecting the icon P13, an attribute corresponding to the preference of the user registered in the user's device from the GPS (Global Positioning System) map information held by the user or the map information published on the Internet. Based on the information, it is also possible to acquire and display map information indicating the position of a shop selling items according to the attribute information.

  In addition, by operating the operation key corresponding to the display switching unit 75, it is possible to perform hierarchical display according to the ontology dictionary without considering the attribute information of the user.

  In addition, when the metadata added to the content data or the content data is text data such as e-mail data, the user address is used for a large number of words (words) included in the title and body text. Register in the attribute information of the data. Thus, without inputting the attribute information itself, the attribute information can be maintained by preparing the content data, such as adding metadata to the content data stored in the own device.

  Further, as described above, attributes such as “like”, “want”, “cheap”, etc., for each word (word) constituting the ontology dictionary for the branded product described with reference to FIGS. If you set the information and create a customized ontology dictionary, the word (word) for which the attribute information of the ontology dictionary is “like” or the word (word) that is “want” ) May be registered as attribute information of user address data.

  In this way, depending on the hierarchy of the ontology dictionary and taking into account the user's attribute information registered in its own device, the content data will be displayed in a systematic manner, which the user will need. The content data can be preferentially displayed.

[Dictionary exchange]
Next, not only address exchange including attribute information but also general dictionary information is exchanged between the cellular phone terminal 100A and the cellular phone terminal 100B configured similarly to the cellular phone terminal 100 of this embodiment. A specific example of the case will be described.

  FIG. 19 is a diagram for explaining examples of display screens of the mobile phone terminal 100A and the mobile phone terminal 100B. It is assumed that each of the mobile phone terminal 100A and the mobile phone terminal 100B is provided with an ontology dictionary for a branded product, which is customized by the user. In addition, it is assumed that attribute information about the user is registered in the user address data.

  In the mobile phone terminal 100A, as shown in FIG. 19A, the product category “normal pattern type / denim” in the sixth hierarchy of the brand ontology dictionary is positioned at the top, and the “normal pattern type / denim” is set. Items such as “GGGG”, “Mini XXX”, and “Mini XXXX”, which are product names of the seventh hierarchy to which the page belongs, are displayed.

  Further, as shown in FIG. 19A, the display screen of the display unit 107 of the mobile phone terminal 100A is extracted through analysis processing such as metadata according to the ontology dictionary, classification processing, and extraction processing according to the attribute information. However, the images SN11, SN12, SN13 corresponding to the image content data, the title of the e-mail data, and other related information are displayed, and icons P11, P12, P13 are displayed.

  Further, in the mobile phone terminal 100B, as shown in FIG. 19B, the product category “shoes” and the “city back” in the fifth hierarchy of the brand ontology dictionary are positioned at the top, and “shoes” Image content extracted through analysis processing, classification processing, and extraction processing according to attribute information such as metadata according to the product category “ordinary pattern type / denim” of the sixth hierarchy and ontology dictionary An image SN21 corresponding to data and an icon P21 for acquiring related information and related information are displayed.

  For “city back”, the product category “normal pattern type / multicolor” in the sixth layer, the analysis processing such as metadata according to the ontology dictionary, the classification processing, and the extraction processing according to the attribute information An icon P22 for acquiring the image SN22 corresponding to the image content data, related information, and GPS map information is displayed.

  The cellular phone terminal 100A and the cellular phone terminal 100B that perform image display as shown in FIG. 19 store and hold attribute information about the user as shown in FIG. FIG. 20 is a list of attribute information regarding the user stored and held in the mobile phone terminal 100A and the mobile phone terminal 100B in this example.

  FIG. 20A is an attribute list related to the user of the mobile phone terminal 100A. As attribute information, name (Aya), gender (female), favorite thing (XX-chan (model), VVVVV (brand name), normal It shows that information such as pattern type denim, bag, pink, jewelry, what you want (cheap brand products, normal pattern type multicolor) is registered.

  FIG. 20B is an attribute list for the user of the mobile phone terminal 100B. As attribute information, name (Mina), gender (female), favorite items (VVVVV (brand name), normal pattern type denim, This indicates that information such as normal pattern type / multi-color, shoes (shoes), OO-chan (model)) and things you want to know (cheap shops, delicious shops) are registered.

  Then, dictionary exchange is performed between the mobile phone terminal 100A and the mobile phone terminal 100B. Here, the dictionary exchange does not simply mean an exchange of ontology dictionaries, but also includes content information (metadata, etc.) that includes attribute information about the user and attribute information of high ratings in addition to information on the missing branch of the ontology dictionary. In other words, content data extracted by performing aggregation based on attribute information (summarization (aggregation result of content data)), collected attribute information on communication partners, and the like can be exchanged together. It shall be possible.

  In the dictionary exchange, exchange conditions can be set. For example, dictionary exchange is performed when there is partial match of attribute information, dictionary exchange is performed when attribute information is totally matched, or partial matching or overall matching of high rating attribute information. In this case, it is possible to set appropriate conditions such as performing dictionary exchange, or performing dictionary exchange when having the same type of ontology dictionary. Further, by exchanging information that can be exchanged and information that cannot be exchanged in advance, it is possible to perform dictionary exchange based only on exchangeable information.

  When the content data is displayed after the dictionary exchange between the mobile phone terminal 100A and the mobile phone terminal 100B, the content data can be displayed as shown in FIG. Is done. FIG. 21 is a diagram for explaining a display example of content data after dictionary exchange.

  When the content data and the like are displayed after exchanging the dictionary between the mobile phone terminal 100A and the mobile phone terminal 100B that have been displaying the content data as shown in FIG. 19, the mobile phone terminal 100A is displayed. As shown in FIG. 21A, in addition to the display contents described with reference to FIG. 19A, a display of a portion surrounded by a dotted line is added according to information from the mobile phone terminal 100B. In other words, the item category “normal pattern type / multicolor” in the sixth hierarchy of the brand ontology dictionary, the image SN22 corresponding to the image content data belonging to the item, related information, and related GPS map information are acquired. An icon P22 for executing the processing to be displayed is displayed.

  Similarly, in the mobile phone terminal 100B, as shown in FIG. 21B, in addition to the display contents described with reference to FIG. 19B, a display surrounded by a dotted line is added according to information from the mobile phone terminal 100A. To be done. In other words, the item “normal pattern type / denim” in the sixth layer of the ontology dictionary of the brand product, the related information belonging to the item, the icon P12 for executing the processing for acquiring the related information, and the related GPS An icon P13 for executing processing for acquiring map information is displayed.

  More specifically, in FIG. 21A, the portion surrounded by a dotted line is displayed as content data having attribute information “like” as metadata in addition to branch information that is lacking in the ontology dictionary, or high rating. The display is realized by receiving content data having the attribute information as metadata from the mobile phone terminal 100B.

  Similarly, in FIG. 21B, the portion surrounded by a dotted line is displayed as content data having attribute information “like” as metadata in addition to branch information that is lacking in the ontology dictionary, and high rating attribute information. This is a display that is realized by receiving content data, etc., that has as a metadata from the mobile phone terminal 100A.

  As described above, the user of the mobile phone terminal 100A and the mobile phone terminal 100B can exchange the dictionaries without performing complicated operations such as manually inputting various information to the mobile phone terminal 100B. Branch information that lacks a dictionary is collected, and in response to this, systematic display of content data is performed so that necessary content data can be used quickly. Although the ontology dictionary is described here as exchanging information on a missing branch part, the entire dictionary may of course be exchanged. Here, the word “exchange” does not mean replacement, but means mutual provision.

  Next, processing when dictionary exchange is performed between the mobile phone terminal 100A and the mobile phone terminal 100B will be described with reference to the processing flow of FIG. FIG. 22 is a processing flow for explaining the processing performed in each of the mobile phone terminal 100A and the mobile phone terminal 100B that perform dictionary exchange and the processing that is performed in cooperation.

  For example, the mobile phone terminal 100A downloads an ontology dictionary from a predetermined system 200 on the Internet in advance and stores it in the nonvolatile memory of the memory unit 105 as its own ontology dictionary AJ (step S100). S11). The ontology dictionary AJ is an ontology dictionary for brand products described with reference to FIGS. 14 and 15, for example.

  The mobile phone terminal 100B also includes an ontology dictionary BJ in the nonvolatile memory of its own memory unit 105. The ontology dictionary BJ is recorded in advance by a manufacturer at the time of manufacture, for example. The ontology dictionary BJ is related to the brand product, similar to the ontology dictionary AJ of the mobile phone terminal 100A. For example, the information on the brand name “EEEEEE” on the fifth hierarchy and below, that is, the product genre and the product category Information on product names and product attributes is not provided. As described above, in the individual examples, the ontology dictionary AJ and the ontology dictionary BJ are dictionaries for the same brand product, but have different branches.

  The mobile phone terminal 100A has user address data A1 and general address data A3, and the mobile phone terminal 100B also has user address data B1 and general address data B2. These user address data A1, B1 and general address data A3, B3 are the same as those described with reference to FIG.

  In the cellular phone terminal 100A, the ontology dictionary AJ is gradually customized and the content data is accumulated by performing dictionary customization processing (step T111) and content data import processing (step S112) as needed. Go (step T11).

  Here, the dictionary customizing process is a process of adding attribute information to each word (class) or adding missing branch information. In addition, the content data capturing process downloads the desired content data through the Internet, collects the content data through the wireless LAN, acquires the content data through the infrared transmission / reception unit 113, and takes an image through the camera unit 118. In this way, image data is acquired.

  Similarly, in the mobile phone terminal 100B, dictionary customization processing (step T211) and content data import processing (step S212) are performed as needed, and the ontology dictionary BJ is gradually customized and content data is accumulated. Go (step T21).

  At this stage, the cellular phone terminal 100A uses a customized ontology dictionary AJ (described as a customized dictionary in FIG. 22) and attribute information of user address data A1 and general address data A3. As shown in FIG. 19A, display regarding content data can be performed (step T12).

  Similarly, in the cellular phone terminal 100B, by using the customized ontology dictionary BJ (described as a customized dictionary in FIG. 22) and the attribute information of the user address data B1 and the general address data B3, FIG. As shown, it is possible to display content data (step T22).

  Thereafter, a communication line is connected (step S12), and dictionary exchange is performed between them (step S13, step S14). Information provided from the mobile phone terminal 100A to the mobile phone terminal 100B in step S13 is information such as ontology dictionary AJ, user address information A1, summary information of contents including these tags, general address data A3, and the like. is there.

  Information provided from the mobile phone terminal 100B to the mobile phone terminal 100A in step S14 includes an ontology dictionary BJ, user address information B1, summary information of contents including these tags, general address data B3, and the like. Information.

  In this embodiment, the control unit 108 of the mobile phone terminal 100A first determines its own device from the summary information of the content including the ontology dictionary BJ and the user address information B1 tag from the mobile phone terminal 100B. A summary of matching contents is extracted in accordance with predetermined conditions such as the ontology dictionary AJ and user address information A1 tag and attribute partial match, attribute total match, or high rating attribute information. In addition, the general address data B3 is added to the general address data A3. In this case, duplicate address data is not added.

  In this embodiment, the control unit 108 of the mobile phone terminal 100B first determines its own device from the summary information of the content including the ontology dictionary AJ and the user address information A1 tag from the mobile phone terminal 100A. A summary of matching content is extracted according to predetermined conditions such as the ontology dictionary BJ and user address information B1 tag and attribute partial match, attribute total match, or high rating attribute information. In addition, a branch that is missing from the ontology dictionary BJ of the own device is extracted from the ontology dictionary AJ and added.

  Then, in the mobile phone terminal 100A, an attribute determination process is executed including information acquired by dictionary exchange (step T13). In this step T13, based on the ontology dictionary AJ, the metadata and title body of the content data are analyzed and classified, and based on the classification result, the attribute information of the user address data A1 is also taken into consideration. Extract content data to be displayed preferentially.

  Based on the attribute determination processing in step T13, content data and the like are displayed (step ST14). In step T14, as described with reference to FIG. 21A, in addition to the display shown in FIG. 19A, display including information obtained by dictionary exchange is performed.

  Similarly, the cellular phone terminal 100B executes attribute determination processing including information acquired by dictionary exchange (step T23). In this step T23, based on the ontology dictionary BJ, the metadata and title body of the content data are analyzed and classified, and based on the classification result, the attribute information of the user address data B1 is also taken into consideration. Extract content data to be displayed preferentially.

  Based on the attribute determination processing in step T23, content data and the like are displayed (step ST24). In step T24, as described with reference to FIG. 21B, in addition to the display shown in FIG. 19B, display including information obtained by dictionary exchange is performed.

  In this way, by exchanging dictionaries, users of each mobile phone terminal can acquire necessary information without having to perform various troublesome operations such as registering various types of information in their mobile phone terminals. By displaying the content data in a systematic manner according to this information, the content data that the user may need can be displayed preferentially.

[Others]
In the above-described embodiment, when address exchange and dictionary exchange are performed, it is described that information is mutually provided. However, the present invention is not limited to this. As long as at least necessary information such as user attribute information of other people and dictionary information can be received from another device, a configuration for providing information from the own device may not be provided.

  In the above-described embodiment, the case where the present invention is applied to a mobile phone terminal has been described as an example. However, the present invention is not limited to this. It is possible to collect content data and collect necessary information such as user attribute information and dictionary information using some means such as wireless LAN, infrared communication, short-range wireless communication, communication via wire, etc. The present invention can be applied to various devices having various configurations, for example, various electronic devices such as a personal digital assistant (PDA), a notebook personal computer, and an electronic notebook.

  In addition, various ontology dictionaries have been created in various fields as well as those related to food and brand products described above, and various ontology dictionaries can be used. Therefore, it is possible to maintain multiple different ontology dictionaries and select which dictionary is used to analyze and categorize the title and body of content data that is metadata or text data added to the content data. You can also do it. In addition, it is possible to analyze and classify the title and body of content data that is metadata or text data added to the content data using each of a plurality of different ontology dictionaries.

  In the above-described embodiment, the case where only the attribute information of the general address data (address book data) in which the address data of the communication destination is accumulated is used or only the user address data is used has been described as an example. However, it is not limited to this. For example, attribute information specific to the user, such as name and gender, is obtained from the user address data, and attribute information according to preferences such as "favorite", "dislike", "desirable" May be collected from both user address data and general address data to form one attribute list data, which may be used for systematic display of content data.

  In the above-described embodiment, the rating of attribute information has been described mainly using the case of appearance frequency, but is not limited to this. As described above, in this specification, the term “rating” means appearance frequency, user prioritization (weighting), rating, ranking, and the like.

  Therefore, for example, the user prioritizes each attribute information (by setting the priority), and extracts content data having the same metadata and word information as the high-priority attribute information that has been set. Of course, you may make it output.

  In addition, ranking is performed for each attribute information, and content data having the same metadata and word information as the attribute information set with a high rank is extracted and output. The content data can be extracted and output using the automatic or manual setting.

  In the above-described embodiment, the case where content data to be displayed such as image data and text data is handled has been described. However, the present invention is not limited to this. Audio content data such as music data can also be included in content data that is systematically output. For example, when content data is systematically displayed and music content data is also included, a title (text data) or an image that is added to the music content data may be output. .

  Further, systematic output of content data is not limited to display. For example, output through a printer, or if the content data is music data, the music content to be output with priority may be specified, and this may be played sequentially to emit sound. .
