Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention refers to a data processing system capable of acting as an electronic secretary system for performing predetermined processing operations in accordance with instructions input by a user, and for providing an interaction between the user and electronic secretary. 2. Description of the Related Art Formerly, there have been some applications, such as computation and word processor systems, in which a human image or some other kind of image is displayed and a voice is generated to improve the user/system interface. As an improvement in a user/system interface by using an autonomously acting agent, a virtual living being system is disclosed in Japanese Patent Laid-Open Publication No. 68063/1994. This system stores into a knowledge database knowledge needed for an autonomously acting virtual living being, this virtual living being simulating an action based on the knowledge stored in the knowledge database and on information stored in an internal state memory means relating to the internal state of the virtual living being and sends out the results to a drawing system, voice system, or the like. Systems for performing an application by using a plurality of pieces of equipment inter-connected through a network include, e.g., a schedule management system described in Japanese Patent Laid-Open Publication No. 6378/1993, but this prior art refers to the internal mechanism and describes nothing about a human interface. When making an information processing equipment performs a series of processing operations, especially when manipulating an application operating in a plurality of pieces of equipment through a communication network, a conventional system has been hard to manage because the internally performed processing becomes difficult for a user to understand. To solve these problems, the present invention provides a data processing system that can achieve an improvement in user/system interface by displaying the internal processing state to a user in an easily understandable form through an animation action of an electronic secretary imitating a human performing various processing operations. Morishima, S et al "Facial Expression Synthesis based on natural voice for virtual face to face communication with machine" 1993, pages 486-491, PROCEEDINGS OF THE VIRTUAL REALITY ANNUAL INTERNATIONAL SYMPOSIUM, US, NEW YORK, IEEE provides a scenario making tool in which facial expressions on a virtual human face displayed on a machine display for user-machine interfacing, are stored in a database, and are selected according to natural voice or text input. EP-A-0438017 discloses a computer system with a user interface in which a displayed control window includes a perspective view of a work area; the area has an active icon, such as an office door or a desk drawer, which can be moved between open and closed positions. SUMMARY OF THE INVENTION According to the present invention, there is provided a data processing system having a user/system interface, the system comprising: an input means for inputting information including user's instructions; a processing means for performing predetermined processing operations in accordance with the input information; a display means for displaying an output of the processing means; an internal state memory means for storing data representing the internal processing state of the processing means; an animation action description data storing means for storing animation action description data relating to respective processing operations of the processing means; and an animation action generation means, responsive to the data stored in said internal state memory means of the particular processing operation performed by the processing means, for generating, using the related animation action description data, data representing human animation of an artificial secretary performing the particular processing operation for display on said display means.

DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a first embodiment of an electronic secretary system according to the present invention will be described referring to the drawings. As shown in Figure 1, an electronic secretary system according to the present invention comprises: an input section 101 as input means, such as mouse and keyboard, for inputting operational information including user's instructions; a processing section 102 as processing means for performing predetermined processing operations in accordance with the input information; a data storing section 103 for storing input information; an internal state memory section 104 as internal state memory means for storing data representing the internal processing state of the processing means; an animation action description data storing section 106 as first animation action description data storing means for storing animation action description data relating to respective processing operations of the processing means; an electronic secretary action data storing section 107 as first data storing means for storing data, such as image of an action and voice, of the electronic secretary; an electronic secretary generation section 105 as animation action decision means for deciding and first generation means for generating an animation action of an electronic secretary as an object imitating a human action corresponding to the internal state out of the action description; a display section 108 for displaying an output of the processing section 102 and an output of the electronic secretary generation section 105; a communication interface 109 for performing data transfer with other equipment connected through a network; and an interpreter section 110 for interpreting data to be transferred and performing data transfer between the processing section 102 and communication interface 109. Data describing an action of the electronic secretary stored in the action description storing section 106 corresponding to the internal state are as shown in Figure 2. The internal state shown in Figure 2 is actually stored together with related data added thereto. The related data include, for example, names of communication partners or contents of retrieval requests, and are auxiliary information for actions of the electronic secretary, for example, information on XX for performing an action of "There was a request from XX." Next, actions of the electronic secretary generation section 105 will be described along the flowchart of Figure 3. The internal state written in the internal state memory section 104 is read by electronic secretary generation section 105 (step S1), while the action description corresponding to the internal state is read out from data stored in the action description storing section 106 (step S2). Based on the action description read out, an action of the electronic secretary is generated (step S3), and a voice, image or the like stored in the electronic secretary action data storing section 107 is outputted to the display section 108 (step S4). These actions are repeated at each elapse of a predetermined time. Next, actions in the case of retrieval will be described along the flowchart of Figure 4. When a user selects a "Retrieval" button by using a mouse or the like (step S11), "Retrieval Start" is written in the internal state memory section 104 by the processing section 102 (step S12) and at the same time a window for keyword input is opened. When "Retrieval Start" is written in the internal state memory section 104, an action of the electronic secretary corresponding to "Retrieval Start" is read out from data of Figure 2 stored in the action description storing section 106, and voice data "Input a keyword", stored in the electronic secretary action data storing section 107 is regenerated. At this time, the mouth of the electronic secretary moves corresponding to an output of voice data, where the movement of the mouth is implemented by an alternate display of images of closed mouse and opened mouth during voice output. From this point on, similarly when a voice is outputted, the mouth of the electronic secretary moves during voice output. Incidentally, the number of internal states may be plural. For example, it can also be set that a state of retrieval start sets in while keeping a state of request receipt. This means that the system stands in an allowable state of receiving a request from a user and the electronic secretary performs an action of retrieval start. When a user inputs a keyword by using a keyboard (step S13), the processing section 102 decides whether the "Break" button was pressed or not (step S14). If the "Break" button is pressed, the retrieval processing is broken off. If deciding that the "Break" button is not pressed, the processing section 102 decides whether the "Retrieval" button is pressed (step S15). If the "Retrieval" button is not pressed, the system returns to the step S14. And if the "Retrieval" button is pressed, "Partner Selection" is written in the internal state storing section 104 (step S16). When "Partner Selection" is written, "Whom do you ask?" is regenerated as an action of the electronic secretary from data of Figure 2. A "Name" button of the partner to be asked for retrieval is selected using a mouse or the like by a user (step S17). A mark is placed on the people selected and it is decided whether the "Break" button is pressed or not (step S18). If the "Break" button is pressed, the retrieval processing is broken off. Or, if the "Break" button is not pressed, it is decided whether the "OK" button is pressed (step S19). If the "OK" button is not pressed, the system returns to the step S18. or, if the "OK" button is pressed, a communication with other equipment starts (step S20). Then, when the transmit processing of requests for all selected communication partners ends (step S21), the processing of retrieval starts (step S22). Retrieval can be executed, for example, by a method for extracting a sentence in which any of keywords of sentence data stored in the data storing section 103 and a keyword inputted by a user is coincident or similar. During retrieval, "During Retrieval" is written into the internal state storing section 104. When the internal state is "During Retrieval", an action of leafing through a book is performed as an electronic secretary's action from data of Figure 2. This processing is performed for all data till the retrieval is completed (step S23). Here, the contents of communication with other equipment will be described in detail. By way of example, a communication between Equipment A (user's name: Ueda) and Equipment B (user's name: Sakamoto) will be described. The contents of communication is outputted from the processing section 102 of Equipment A to the interpreter section 110. The information of a communication partner and that of the contents of communication are converted into communication codes by the interpreter section 110 and outputted to the communication interface 109. Actual transfer of data is performed by the communication interface 109. As shown in Figure 5, the internal state in Equipment A and Equipment B, an action of the electronic secretary, and transmit data are provided. First, a request for communication start from Equipment A to Equipment B is transmitted. At this time, the internal state becomes "Communication Start Transmit", the electronic secretary performs an action of telephoning in accordance with Figure 2. In Equipment B, data of communication start request are received from Equipment A, the internal state becomes "Communication Start Receive", and data of "OK" is transmitted as a reply. At this time, the electronic secretary of Equipment B performs an action of receiving a telephone and a voice of "Hello, this is (Sakamoto's) secretary speaking." is regenerated. Incidentally, the name in a bracket is a user's name set for each equipment and differs with equipment. In Equipment A that has received data of OK, the internal state becomes "Request Transmit" and the contents of request is transmitted. In the case of retrieval, the contents of request comprise keyword, name of the retrieval requesting user ("Ueda" in this example), name of the retrieval result output file, and the like. The format is, for example, as follows: Search ("Computer Kagaku", "Ueda", "kensaku.txt"), where Search means a request of retrieval. At this time, the electronic secretary in Equipment A regenerates "This is (Ueda's) secretary speaking and there is a request from (Ueda)". The internal state of Equipment B that has received the contents of request becomes "Request Receive" and OK data is transmitted as a reply. At this time, the electronic secretary in Equipment B regenerates "I've understood and I'll tell (Sakamoto). The internal state of Equipment A that has received OK data becomes "Communication End Transmit" and a request of communication end is transmitted. The internal state of Equipment B that has received a request of communication end becomes "Communication End Receive" and the electronic secretary of Equipment B performs an action of hanging up. After the above series of communication ends, the contents of request are executed. In this example, the retrieval is executed. Next, a series of actions: receiving a request through communication, then executing the request, till returning the result of the request will be described along the flowchart of Figure 6. Keep waiting till a request from other equipment occurs (step S25). When a request occurs, receive the request following the above procedure (step 26) and execute the request (step S27). Then, transmit the result of the request to the equipment of the user that has advanced the request (step S28). Furthermore, turn the internal state into "Request End". At this time, the electronic secretary performs an action of raising her hands from data of Figure 2. Next, the procedure of communication concerning the reply of request result between Equipment B and Equipment A will be described using Figure 7. First, the internal state of Equipment B becomes "Communication Start Transmit" and a request for communication start is transmitted to Equipment A. The internal state of Equipment A that has received a request for communication start becomes "Communication Start Receive" and data of OK is transmitted as a reply. The internal state of Equipment B that has received OK data becomes "Retrieval Result Transmit". The electronic secretary of Equipment B regenerates "We'll transmit the retrieval result" and the content of request result is transmitted. The transmitted content contains the header part and text of retrieved sentences, similarity of each sentence and the keyword, name of transmitting user, and the like. The internal state of Equipment A that has received the retrieval result becomes "Retrieval Result Receive" and data of OK is transmitted as a reply. At this time, the electronic secretary of Equipment A regenerates "We're obliged." Next, the internal state of Equipment B that has received OK data becomes "Communication End Transmit" and a request of communication end is transmitted. The request of communication end is received by Equipment A and the internal state becomes "Communication End Receive". Next, the processing procedure of equipment when transmitting the requirements of a request and waiting the request result will be described along the flowchart of Figure 8. Keep waiting till a request of communication occurs (step S30). When a request of communication occurs, receive the request result as mentioned above (step S31). And, repeat the above processing till the request results return from all equipment to which the request are transmitted (step S32). When the results are transmitted from all equipment, the internal state becomes "Retrieval End" (step S33). Next, a second embodiment of an electronic secretary system according to the present invention will be described referring to the drawings. As shown in Figure 9, an electronic secretary system according to the present invention comprises: an input section 101, such as mouse and keyboard, for inputting operational information; a processing section 102 responsive to the input information for performing a predetermined processing; a data storing section 103 for storing input information; an internal state memory section 104 for memorizing the internal state of processing; an action description storing section 106 for storing the action description of an electronic secretary as an object imitating a human action; an electronic secretary action data storing section 107 for storing data, such as image of an action and voice, of the electronic secretary; an electronic secretary generation section 105 for deciding and generating an action of the electronic secretary corresponding to the internal state out of the action description; a display section 108 for displaying an output of the processing section 102 and an output of the electronic secretary generation section 105; a communication interface 109 for performing data transfer with other equipment connected through a network; an interpreter section 110 for interpreting data to be transferred and performing data transfer between the processing section 102 and communication interface 109; a second action description storing section 112 as second action description storing means for storing data describing the action of the electronic secretary in one or more communication partners; a second electronic secretary action data storing section 113 as second data storing means for storing data, such as image of an action and voice, of the electronic secretary; and a second electronic secretary generation section 111 as second generation means for generating an action of the electronic secretary. Next, actions during communication will be described. As shown in Figure 5, when advancing a request from Equipment A to Equipment B, the internal state of Equipment A becomes "Communication Start Transmit" and a request of communication start is transmitted to Equipment B. At this time, not only a request of communication start but also the user's name and internal state of Equipment A on the transmitter side are transmitted. In the interpreter section 110 of Equipment B on the receiver side, a request of communication start is outputted to the processing section 102 and the user's name and internal state, information related to the electronic secretary of Equipment A is outputted to the second electronic secretary generation section 111. In the second electronic secretary generation section 111, the action description of an electronic secretary corresponding to the internal state and data on an action of the electronic secretary responsive to the user's name are read from the second action description storing section 112 and second electronic secretary action data storing section 113 respectively, and actions of the electronic secretary are generated. Here, with respect to data on a second action description and second electronic secretary action data, it is considered that at the start of communication data are previously prepared for a plurality of communication partners, action describing data and second electronic secretary action data are selected responsive to a communication partner, and an action of another electronic secretary is generated, or that at the start of communication, data on a second action description and second electronic secretary action data are transmitted and stored in a second action description storing section 112 and second electronic secretary action data storing section 113 at the destination, respectively. Next, the above-mentioned example of actions will be described referring to an actual display screen. As shown in Figure 10, the initial screen of the display displays a schedule button 1, mail button 2, retrieval button 3, data button 4 and note button 5 which correspond to individual processing at the lower left, and an electronic secretary 6 and secretary button 7 on the right. In the middle of the screen, there are a button 21 materializing a calendar, a button 22 materializing a mailbox, a button 24 materializing a data file, and a button 25 materializing a notebook, which perform the respective processing similar to that of the schedule button 1, mail button 2, data button 4 and note button 5. Here, when pressing the retrieval button 3, a window 8 for keyword input as shown in Figure 11 comes to appear and a user inputs a keyword from the keyboard and the like. Here, when pressing the retrieval button in the window 8, a window 9 for displaying the names of those whose request is asked comes to appear as shown in Figure 12. Then, when pressing a name button, a mark for indicating a selection of the relevant person is put on the name button pressed. In the illustrated example, "Self", "Sakamoto" and "Matsuoka" are selected. Then, when pressing the OK button 10, a communication with those selected above starts. Figure 13 shows an example of a communication with the electronic secretary 11 of "Sakamoto". An action of the electronic secretary of another equipment is displayed on the upper right screen. Figure 14 shows an example of a communication with the electronic secretary 12 of "Matsuoka". After the communication with other equipment ends, a processing of retrieval starts. Figure 15 shows a book-leafing action of an electronic secretary engaged in retrieval. Figure 16 shows an example of receiving the retrieved result. Figure 17 shows an action of an electronic secretary when the request results are returned from all equipment and the retrieval ends. Here, when pressing the secretary button 7, a window 13 for the list of retrieved results is displayed as shown in Figure 18. The header part 14 of the retrieved sentences, similarity 15 to retrieved keywords and name 16 of returning users of request results is respectively displayed in the window 13. Then, when pressing a button 17 in the header part of sentences, a window 18 having the text of a sentence written thereon is displayed as shown in Figure 19. Next, an action performed when a user presses the secretary button 7 will be described along the flowchart of Figure 20. When a user presses the secretary button 7 (step S40), the internal state is checked (step S41). If the internal state is "Retrieval End", the internal state is anew turned into "Retrieved Result" (step S42). An action description is read that corresponds to the internal state "Retrieved Result", "The retrieved results are ready" is regenerated and at the same time the retrieved results are displayed (step S43). Or, if the internal state is "Request End", the internal state is anew turned into "Request Reply" (step S44). At this time, an action description is read that corresponds to the internal state "Request Reply". "There has been a request (for retrieval) from Mr (Ueda)" is regenerated and the requested results are displayed (step S45). On the other hand, if the internal state is otherwise, the internal state is anew turned into "Help" (step S46). An action description is read that corresponds to the internal state "Help" and a help screen as shown in Figure 21 is displayed (step S47). In this example, the state of the self equipment and communication partner equipment is indicated by animation, voice and the like, but may be indicated only by sentences if they represent the state of self and partners. Next, a third embodiment of an electronic secretary system according to the present invention will be described referring to Figure 22. Incidentally, by putting like symbols to constituents similar to those of Figures 1 and 9 , description is omitted. The present embodiment is featured by comprising a mode storing section 114 as mode storing means for storing the work environment of a user. Values set depending on the work environment of equipment are stored in the mode storing section 114. For example, in an equipment that cannot output voice data, a mode to output no voice is set and no voice is outputted when the electronic secretary acts. In this case, it can also be considered to output the voice content in letter. Also, in an equipment that cannot output image data, a mode to output no image is set and no action of the electronic secretary is outputted. In this case, it can also be considered to output the action content of the electronic secretary in letter. Also, it can be considered that a different value is set for each equipment, for example, the background to be displayed for an electronic secretary is varied with individual equipment. Next, a fourth embodiment of an electronic secretary system according to the present invention will be described referring to Figure 23. Incidentally, by putting like symbols to constituents similar to those of Figures 1, 9 and 22, description is omitted. The present embodiment is featured by comprising an internal state generation section 115 for generating the internal state in according with a predetermined principle. The internal state is generated by the internal state generation section 115 in according with a predetermined principle. For example, at each time determined with a random number, "wink" is written into the internal state memory section 104. When "wink" is described in the internal state memory section 104, the electronic secretary performs an action of wink in accordance with Figure 2. An action of wink can be implemented by alternately displaying images of opened eye and closed eye. The timing of writing is considered to be performed at each predetermined time or at intervals of time determined with a random number. Also by comprising timing generation means, it is possible to switch the background of an electronic secretary between that of morning, that of noon and that of night in dependence on the time of day, or to match the background with spring, summer, autumn or winter in dependence on changes of the season, or to change the costume of an electronic secretary. Next, a fifth embodiment of an electronic secretary system according to the present invention will be described referring to Figure 24. As shown in Figure 24, an electronic secretary system according to the present invention comprises: an input section 101, such as mouse and keyboard, for inputting operational information; a document data storing section 123 as storing means for storing document data as data to be retrieved; a retrieval section 122 as retrieval means for retrieving data pertinent to the retrieval condition inputted using the input section 101 from the document data storing section 123 distributed in a plurality of equipment connected through a network; an internal state memory section 104 for memorizing the internal state of processing; an action description storing section 106 for storing the action description of an electronic secretary as an object imitating a human action; an electronic secretary action data storing section 107 for storing data, such as image of an action and voice, of the electronic secretary; an electronic secretary generation section 105 for deciding and generating an action of electronic secretary corresponding to the internal state out of the action description; a display section 108 for displaying an output of the retrieval section 122 and an output of the electronic secretary generation section 105; a communication interface 109 for performing data transfer with other equipment connected through a network; an interpreter section 110 for interpreting data to be transferred and performing data transfer between the retrieval section 122 and communication interface 109; a second action description storing section 112 for storing data describing the action of the electronic secretary in one or more communication partners; a second electronic secretary action data storing section 113 for storing data, such as image of an action and voice, of the electronic secretary; and a second electronic secretary generation section 111 for generating an action of the electronic secretary. Next, actions in the case of retrieval will be described along the flowchart of Figure 4. When a user selects a "Retrieval" button by using a mouse or the like (step S11), "Retrieval Start" is written into the internal state memory section 104 by the retrieval section 122 (step S12) and at the same time a window for keyword input is opened. When "Retrieval Start" is written in the internal state memory section 104, an action of the electronic secretary corresponding to "Retrieval Start" is read out from data of Figure 2 stored in the action description storing section 106, and voice data "Input a keyword", stored in the electronic secretary action data storing section 107 is regenerated. At this time, the mouth of the electronic secretary moves corresponding to an output of voice data, where the movement of the mouth is implemented by an alternate display of images of closed mouse and opened mouth during voice output. From this point on, similarly when a voice is outputted, the mouth of the electronic secretary moves during voice output. Incidentally, the number of internal states may be plural. For example, it can also be set that a state of retrieval start sets in while keeping a state of request receipt. This means that the system stands in an allowable state of receiving a request from a user and the electronic secretary performs an action of retrieval start. When a user inputs a keyword by using a keyboard (step S13), the retrieval section 122 decides whether the "Break" button was pressed or not (step S14). If the "Break" button is pressed, the retrieval processing is broken off. If deciding that the "Break" button is not pressed, it is decided whether the "Retrieval" button is pressed (step S15). If the "Retrieval" button is not pressed, the system returns to the step 14. Or, if the "Retrieval" button is pressed, "Partner Selection" is written in the internal state storing section 104 (step S16). When "Partner Selection" is written, "Whom do you ask?" is regenerated as an action of the electronic secretary from data of Figure 2. A "Name" button of the partner to be asked for retrieval is selected using a mouse or the like by a user (step S17). A mark is placed on the people selected and it is decided whether the "Break" button is pressed or not (step S18). If the "Break" button is pressed, the retrieval processing is broken off. Or, if the "Break" button is not pressed, it is decided whether the "OK" button is pressed (step S19). If the "OK" button is not pressed, the system returns to the step S18. Or, if the "OK" button is pressed, a communication with other equipment starts (step S20). Then, when the transmit processing of requests for all selected communication partners ends (step S21), the processing of retrieval starts (step S22). Retrieval can be executed, for example, by a method for extracting a sentence in which any of keywords of sentence data stored in the document data storing section 123 and a keyword inputted by a user is coincident or similar. During retrieval, "During Retrieval" is written into the internal state storing section 104. When the internal state is "During Retrieval", an action of leafing through a book is performed as an electronic secretary's action from data of Figure 2. This processing is performed for all data till the retrieval is completed (step S23). Next, actions during communication will be described. As shown in Figure 5, when advancing a request from Equipment A to Equipment B, the internal state of Equipment A becomes "Communication Start Transmit" and a request of communication start is transmitted to Equipment B. At this time, not only a request of communication start but also the user's name and internal state of Equipment A on the transmitter side are transmitted. In the interpreter section 110 of Equipment B on the receiver side, a request of communication start is outputted to the retrieval section 122 and the user's name and internal state, information related to the electronic secretary of Equipment A is outputted to the second electronic secretary generation section 111. In the second electronic secretary generation section 111, the action description of an electronic secretary corresponding to the internal state and data on an action of the electronic secretary responsive to the user's name are read from the second action description storing section 112 and second electronic secretary action data storing section 113 respectively, and actions of the electronic secretary are generated. Next, a sixth embodiment of an electronic secretary according to the present invention will be described referring to Figure 25. Incidentally, by putting like symbols to constituents similar to those of Figure 1, description is omitted. The present embodiment is featured by comprising: a retrieval section 124 for performing a retrieval of schedule data through a network; a registry/deletion section 125 for performing a registry or deletion of schedule data through a network; and a schedule data storing section 126 for storing schedule data. Next, actions of the transmit side and receive side will be described along the flowcharts of Figure 26. First, actions of the transmit side will be described along the left flowchart of Figure 26. When the flow of Figure 26 is called from the main flow of Figure 26 and a schedule setting mode sets in, the internal state is turned into schedule setting by the processing section 102 in the internal state memory section 104 (step S51). A screen for setting a schedule as shown in Figure 27 is displayed on the display section 108 and the system waits an input of schedule data from a user (step S52). When the internal state changes, an electronic secretary action is generated in accordance with Figures 2 and 3. Incidentally, Figure 2 describes part of actions and does not describe some of those appearing in the flow of Figure 26. As shown in Figure 28, the internal state is made a communication partner of by the processing section 102 (step S53). An input of a transmit partner in a request of schedule is waiting for (step S54). As shown in Figure 29, the internal state is turned into communication start transmit (step S55). Request for communication to the equipment of a specified partner is generated (step S56). It is decided whether a connection to the communication partner is established or not (step S57). If no connection with communication partner is established, a decision of communication connection is performed (step S58). As a result, if no connection was possible, the internal state is turned into absence, and notice is given to a user through an electronic secretary that no connection with the partner was possible. Then, the internal state is turned into discontinue processing and notice is given to a user through an electronic secretary that attempt to make a connection will be given up (step S59). Then, end processing is performed (step S60). Incidentally, when a connection was impossible, various other processing, such as asking a user whether request for reconnection is performed or not, are considered. In the above step S57, when a connection with the communication partner is established, the internal state is turned into request transmit (step S61), and notice is given to a user through an electronic secretary that a request for a current schedule is sent to the communication partner. Actually, a request for schedule is sent to the communication partner (step S62). The result of whether a request is accepted or not is waited (step S63). The internal state is turned into receive result (step S64), notice is given to a user through the electronic secretary that the result of schedule request arrived from the communication partner. It is decided whether the result of schedule request is OK or not OK (step S65). If the result of schedule request is OK, the internal state is turned into result OK and the electronic secretary is made to indicate that the request was accepted (step S66). As shown in Figure 30, the detailed result of schedule request is displayed (step S67). Or, if the result of schedule request is not OK, the electronic secretary is made to indicate that the request was rejected. Here, only the outline of the currently processed content is displayed using voice/letter or image to a user by the electronic secretary and the detailed information is presented directly to a user. However, by writing not only state information, such as waiting for simple request receive, about internal state, but also detailed information, such as date, time, partner and content of schedule request presented, into the internal state, it is also possible that an electronic secretary indicates detailed information collectively to a user. Furthermore, the end processing, such as end of communication accompanying the end of schedule setting is performed (step S60). Next, actions on the receive side will be described along the right flowchart of Figure 26. The internal state is turned into request receive wait,' and an electronic secretary is made to display the request receive wait (step S71). The system comes to wait for receiving the communication request through a network (step S72). A connection request is received and a network is established (step S73). The internal state is turned into communication start receive, and the electronic secretary is made the display of replying (step S74). A request for schedule is received (step S75). The internal state is turned into request receive and the electronic secretary is made the display of receiving a request (step S76). As shown in Figure 31, the details of the request is displayed (step S77). A user's input telling the intention to accept or to refuse the schedule request is waited for and the input is checked (step S78). If the request is refused, not OK is transmitted (step S79). Or, if accepted, OK is transmitted (step S80). The internal state is turned into result transmit and the electronic secretary is made the display of transmitting the results (step S81). The end processing, such as end of communication, is performed (step S82). Next, a seventh embodiment of an electronic secretary system according to the present invention will be described referring to Figure 32. Incidentally, by putting like symbols to constituents similar to those of Figures 1, description is omitted. The present embodiment is featured by comprising: a history memory section 127 as history memory means for memorizing the history of the internal state to be memorized in the internal state memory section 104. Incidentally, if there is a problem in that the memory capacity becomes insufficient when the whole history is memorized, a ring buffer in which a predetermined number of histories from the most recent are memorized is desirable. Also, inside the history memory section, there are a time generation section and a consecutive number generation section and it is desired to memorize the generating time and the serial number of the internal state as well as the internal state. And, on the display section 108, the history including detailed information among the internal state is displayed, for example as shown in Figure 33. Next, an eighth embodiment of an electronic secretary system according to the present invention will be described referring to Figure 34. Incidentally, by putting like symbols to constituents similar to those of Figure 1, description is omitted. The electronic secretary system comprises: an electronic mail processing section 128 as electronic mail processing means for processing data interpreted as an electronic mail by the interpreter section 110; an electronic mail storing section 129 for storing data interpreted as an electronic mail; a header storing section 130 as header storing means for storing the header information of an electronic mail letter; and a classification section 131 as classification means for classifying the electronic mail letters stored in the electronic mail storing section 129. Actions of the electronic secretary corresponding to the internal state stored in action description storing section 106 include not only those shown in Figure 2 but also those shown in Figure 35. The internal state written in the internal state memory section 104 is read out by electronic secretary generation section 105. The action description corresponding to the internal state is read from data stored in the action description storing section 106. Based on the read action description, a voice, image or the like stored in the electronic secretary action data storing section 107 are displayed on the display section. The number of internal states may be plural. These actions are repeated at each predetermined time, or performed whenever the internal states change. Next, the classification processing will be described along the flowcharts of Figures 36a and 36b. First, when a user presses a "mail" button (step S91), "Mail Start" is written into the internal state memory section 104 by the processing section 102 (step S92). From data stored in the action description storing section 106 as shown in Figure 35, the action description corresponding to the internal state is read out and a mail screen is displayed on the display section 108. In an electronic mail letter, a mail flag is set by the electronic mail processing section 128. The mail flag is set to 1 for an electronic mail letter not yet read and to 0 for an electronic mail already read. By the electronic mail processing section 128, electronic mail letters having the mail flag of 1 are retrieved and the header information is displayed in a list (step S93). Then, when a user presses a "classifying" button (step S94), "Classifying Start" is written into the internal state memory section 104 (step S95). From data shown in Figure 35, voice data "Classify", stored in the electronic secretary action data storing section 107, is regenerated and classifying starts. While classifying starts, "During Classifying" is written into the internal state memory section 104 (step S96) and in accordance with data shown in Figure 35, the manner of an electronic secretary classifying the "header" buttons according to categories is displayed (step S97). When classifying ends, "Classifying End" is written into the internal state memory section 104 (step S98), an action of "During Classifying" is completed in accordance with data shown in Figure 35. The classified results are delivered to the processing section 102, classified according to categories and outputted from the display section 108 (step S99). At this time, an "End" button is displayed. When a user presses the "End" button (step S100), "Mail End" is written into the internal state memory section 104 (step S101) and the mail screen closes in accordance with data shown in Figure 35. Or, when a user does not press the "End" button, press of the "header" button by a user (step S102) causes the electronic mail letter corresponding to the header pressed to be retrieved in the electronic mail processing section 128 and the content of the electronic mail letter is displayed (step S103). When the content of the electronic mail letter is called in the electronic mail processing section 128, the mail flag for the electronic mail letter is set to 0 (step S104). Then, it is decided whether a user pressed a "Close" button or not (step S105). If a user presses the "Close" button, the indication of the content distinguishes and the system returns to the above step S100. Or, if it was decided that a user did not press the "Close" button, it is decided whether a user pressed a "Reproduce" button (step S106). If it was decided that a user did not press the "Reproduce" button, the system returns to the above step S105. If it was decided that a user pressed the "Reproduce" button, "Mail Reproduce" is written into the internal state memory section 104 (step S106), and image data, voice data or the like contained in data of the electronic mail letter are reproduced in accordance with data shown in Figure 35. Then, the processing to be performed when a new electronic mail arrived will be described along the flowchart of Figure 37. When the electronic mail arrives at the communication interface 109 (step Sill), data of the electronic mail is sent to the electronic mail processing section 128 through the interpreter section 110. At this time, "Mail Arrival" is written into the internal state memory section 104 (step S112) and in accordance with data stored in the action description storing section 106 as shown in Figure 35, an action of the electronic secretary receiving a postal card is outputted from the display section 108. An electronic mail is stored in the electronic mail storing section 129 by the electronic mail processing section 128 (step S113) and the header information is stored in the header storing section 130 (step S114). The mail flag of this electronic mail is set to 1 (step S115). "Mail Unprocessed" is written into the internal state storing section 104 (step S116) and in accordance with data stored in the action description storing section 106 as shown in Figure 35, a postal card is displayed on the desk of an electronic secretary. So long as an electronic mail having the mail flag of 1 is present in the electronic mail processing section 128, the internal state remains "Mail Unprocessed" and the display of the postal card is kept to be outputted. Next, actions of classifying will be described along the flowchart of Figure 38. When a user presses a "Classify" button while the header information of electronic mail having the mail flag of 1 is displayed in the list, first, data of the first electronic mail letter are retrieved from the electronic mail storing section 129 and the component vector is calculated (step S121). Incidentally, categories of classifying are set by a user in advance, a reference vector is calculated for each category, and the data shall be possessed by the classifying section 131. A similarity between the component vector of an electronic mail letter and the reference vector of each category is calculated (step S122). In evaluating the similarity, various methods, such as by computing the inner product or difference of vectors, are considered, but either method is possible. If the similarity is calculated concerning all categories (step S123), the name of the highest category in similarity and a value of similarity are extracted (step S124). The display of "header" buttons is so modified as to easily find the relevant category from the extracted category names in the display section 108 (step S125). For example, such processing as collectively displaying those of the same category or distinguishing different categories by color, is performed. Also, the similarity is simultaneously displayed (step S126), or the degree of closeness to a certain category is made clear. These calculations are performed for all listed electronic mail letters. When all calculations end (step S127), the classifying end flag is turned into 1 (step S128). "Classifying End" is written into the internal state storing section 104 and in accordance with data stored in the action description storing section 106 as shown in Figure 35, the electronic secretary finishes the action of "During Classifying". Incidentally, not only an electronic mail letter not yet read but also those already read can be also classified. The processing-of this case is also performed like the above. Next, the classifying processing will be described using a concrete example. As shown in Figure 39, an electronic mail letter comprises an electronic mail text and a "header" button. Figure 39 (b) shows a displayed example of 3 items, a transmitter, a received date and the content, extracted as header information. As shown in Figure 40, the categories for classifying shall be set by a user. In the classifying section 131, the component vector is calculated concerning the electronic mail letter of Figure 39 (a). The similarity between this component vector and the reference vectors of three categories in Figure 40 is respectively evaluated. As shown in Figure 41 (a), it is obtained as the calculated results that the similarity is 66 for the category 1 (VR relation), 27 for the category 2 (neuro relation) and 50 for the category 3 (others). The highest similarity among them is a similarity of 66 for the category 1, and accordingly this letter is classified into the category 1, so that the category 1 and similarity 66 are extracted. Figure 41b shows the extracted results. Seeing the result as indicated in Figure 41 (b), the display section 108 displays "header" buttons shown in Figure 39 (b) at the category 1 as shown in Figure 41c, where "header" buttons of the electronic mail classified according to categories are displayed in the respective categories. A "score" indicated by the side of a "header" button represents the similarity. In Figure 41c, the arrangement of electronic mail letters in each category is in the order of arrival. As shown in Figure 41d, a method for display electronic mail letters in sequence from the highest similarity can be also considered. In this case, it is advisable that after category names and similarity are extracted for all electronic mail letters, values of similarity are compared for the electronic mail letters belonging to the same category and the letters are arranged in sequence from the highest similarity in each category. Next, the above example of action will be described in an actual display screen. When a user presses a "Mail" button, a mail screen as shown in Figure 42 is opened, the list of header information in electronic mail letters not yet read is displayed. Hereupon, when pressing a "Classify" button, the manner of an electronic secretary to classify the "header" buttons is displayed as shown in Figure 43. Figure 44 shows the classified results, where electronic mail letters are separately displayed under classification by categories of their "header" buttons. The item indicated by scores is a similarity, while classified categories and similarity are indicated. Herein, when a user presses a definite "header" button, a window for showing the content of electronic mail letters corresponding to a pressed "header" button is displayed as shown in Figure 45. At this time, a check mark is put on the pressed "header" button, which indicates the relevant electronic mail letter has been read. When pressing a "Reproduce" button denoted by a picture of speaker, image data, audio data or the like are reproduced. When pressing a "Close" button, the mail screen closes and the processing of electronic mail letters ends. As shown in Figure 46, an example of display when a new electronic mail arrived displays a postal card receiving manner of an electronic secretary. As shown in Figure 47, an example of display when an electronic mail having the mail flag of 1 is included in the electronic mail storing section 129 displays an image that a postal card is placed on the desk of the electronic secretary, which informs a user of electronic mail arrival. Next, a ninth embodiment of an electronic secretary system according to the present invention will be described referring to Figure 48. Incidentally, by putting like symbols to constituents similar to those of Figure 34, description is omitted. The present embodiment is featured by comprising the classify mode storing section 132 as classify mode storing means for storing the classify mode in accordance with an instruction to be inputted from the input section 101. In the classify mode storing section 132, values set on classify modes in the classify section 131, estimating function, and method for indicating the classified results are stored. Next, the procedure for setting a classify mode will be described along the flowchart of Figure 49. When a user selects the "Classify Mode Setting" (step S131), "Classify Mode Setting" is written into the internal state memory section 104 (step S132). In accordance with data stored in the action description storing section 106 as shown in Figure 35, a screen for setting a classify mode is displayed and the list of classify modes stored in the classify mode storing section 132 is displayed. As shown in Figure 50, examples of classify modes include "By Content", classifying by the content of electronic mail letters; "By Transmitter", classifying by transmitters; "By Group", classifying by the belonging group of transmitters; and "By Date", classifying by the received date of electronic mail letters. It is advisable that, by preparing the item of "user Setting", a user himself can set a classify mode. When a classify mode is selected by a user from the list of classify modes (step S133), an alteration in classify mode is performed in the classify mode memory section 132 (step S134). Thereafter, an alteration in estimation function is performed according to a set classify mode (step S135). Figure 51 shows an example of estimation function. In the mode 1, "By Content", as described in a first embodiment, the similarity between the component vector of a sentence and the reference vectors is calculated and the relevant mail letter is classified in a category of the highest similarity. In the mode 2, "By Transmitter", one letter is picked up from among the electronic mail to be classified and the similarity with others is calculated. In this case, seeing the header information, to the similarity is assigned 1 for electronic mail letter of the same transmitter and 0 for that of a different transmitter, where the electronic mail having a similarity of 1 are collectively classified in one and the same category. This operation is continued till the whole electronic mail is classified. In the mode 3, "By Group", after registering the members of each group in advance, electronic mail letters are classified referring to a name of transmitter among the header information into belonging groups. In the mode 4, "By Date", seeing dates of the header information as with the mode 2, to the similarity is assigned 1 for those of the same date and 0 for others, where the electronic mail having a similarity of 1 are collectively classified in one and the same category. In relation to the memorized classify mode, an estimation function is set in advance but can be altered by a user. Then, returning to Figure 49, a display method is altered in accordance with a classify mode (step S136). In dependence on a classify mode, examples of display methods are as follows: In the mode 1, "By Content", "header" buttons are collected in display for each category as shown in Figures 41c and 41d. In the mode 2, "By Transmitter", "header" buttons are listed in display for each transmitter as shown in Figure 52a. In the mode 3, "By Group", "header" buttons are divided in display for each group as shown in Figure 52b. In the mode 4, "By Date", "header" buttons are divided in display for each date as shown in Figure 52c. Similarly in other modes, a display method is set for each mode. Thereafter, the display of similarity is set. If set to "the similarity is not displayed", such can be set that the similarity is not displayed. Meanwhile, when the similarity represents the closeness to the relevant category as withtheeighth embodiment, an electronic mail letter having a higher similarity may be regarded as high in priority. At this time, it can be set in such a manner as to display the electronic mail in sequence from the highest similarity. Furthermore, in the above step S133 of Figure 49, when selecting a "User Setting", a user sets a classifying method from the input section 101 (step S137). Hereupon, setting of an estimation function (step S138) and setting of a display method (step S139) are respectively performed. The classify mode set by a user is registered in the classify mode storing section 132 (step S140), to which a mode number is assigned. In this way, if a classify mode is set, "Mode Setting Completion" is written into the internal state storing section 104 (step S141). The screen for setting a classify mode closes and the processing ends. In selection of a classify mode, when selecting "Discontinue", an alteration in classify mode is not performed and the processing ends. Actions to be performed when a user presses a "Classify" button were described, but such setting is thinkable that classification can proceed when a user presses a "Mail" button. In this case, the classified results are arranged to be displayed instead of the list of electronic mail. This invention extends to the disclosed methods of facilitating communication at the man-machine interface of an office data processing system or electronic secretary system. The invention may be embodied in other specific forms without departing from its scope as defined by the claims.
