FIG. 1 shows a basic embodiment of the present invention. Reference numeral 2 denotes a structured document generation device capable of transmitting and receiving non-character data such as audio data, still image data or moving image data, and converting these into text data. The converted structured document can be transmitted and received. The structured document generation device 2 can read still image data and the like, and reads a program for generating a structured document from an appropriate storage medium and executes the program. The structured document generation device 2 is connected to the LAN 4 and performs transmission and reception of non-character data and transmission and reception of a structured document.
In addition, it is connected to the public telephone network (PSTN)
Sends and receives facsimile data. Further, it is connected to a network such as the Internet and transmits and receives Internet facsimile, moving image data, audio data, and the like.

The structured document generation device 2 has a data extraction and
There is a conversion unit 6 and a text conversion unit 8, and the data extraction / conversion unit 6 extracts information to be used as an attribute of the structured document from information on the communication itself, and converts a part of the attribute into data that is easier to handle. To the attributes of the structured document, and the rest is converted as is to the attributes of the structured document. Further, the data extraction / conversion unit 6 adds data indicating a conversion method from non-character data to text data to the attribute as data for conversion to the original non-character data. In addition, a title or the like may be input as appropriate to make it an attribute. When used as an image scanner, the date and time of scanning, the number of sheets, scanning conditions, and the like are added to the attribute as keywords. The text conversion unit 8
The main body of the non-character data received by communication is converted into text data. The structured document generation device 2
A structured document generation program stored in a storage medium 9 such as a VD or a CD-ROM is read, and accordingly, its own resources are allocated to a data extraction / conversion unit 6 and a text conversion unit 8 to generate the structured document 10. Be able to do it. The structured document 10 is composed of two parts: the ID of the sender, the type of data, the data for restoration for converting the text data into non-character data, the transfer destination, and the like, and the text data. I have. The structured document 10 is transferred from the structured document generation device 2 to a predetermined destination such as the structured document processing device 12 via the LAN 4 or the like.
In FIG. 1, for the sake of illustration, the display is as if it were not via the LAN 4.

The structured document processing device 12 performs processing such as data conversion to original non-character data, print, display, storage, distribution (transfer), etc., using the attributes of the structured document, and performs processing of the structured document. Processing program for DVD or CD-R
It is read from the storage medium 13 such as OM. In order to determine these processing contents, the data extraction unit 14 extracts an attribute structured information or the like relating to the communication itself, and searches the processing condition used in the processing condition storage unit 16 using the extracted data. The processing of the transferred structured document is determined according to the above. The non-text converter 18 converts the data body in the structured document into the original non-character data. The storage unit 20 stores the structured document itself, its processing, main attributes, and the like.

The embodiment shown in FIG.
FIG. 2 shows a specific example of the relationship between the document management server 24 and the document management server 24. The facsimile server 22 and the document management server 24 are connected via the LAN 4, and facsimile data is transmitted to the facsimile server 22 from the Internet or a public telephone line network. The facsimile data includes, in addition to the still image data serving as the data itself, the transmission source address, resolution, encoding method, paper size, number of data, confidential transmission, polling transmission, and other special mode transmission. Data regarding the communication itself, such as a mode, is added. In the facsimile server 22 that has received the facsimile data, the received date and time, the number of the receiving device when there are a plurality of receiving devices, the communication time, the communication result, etc.
Generates information that is found on the receiving device side. The information on the communication itself received by the facsimile server 22 and the information on the communication itself that can be generated by the facsimile server 22 are set as information on the communication itself. Data is extracted from the information on the communication itself by the data extraction / conversion unit 6, and a part of the data is handled such as the titles of documents such as design drawings and accounting documents, related client names, circulation, distribution to all members, and secret class 2. Convert to conditions etc. Further, data for conversion between text data / non-character data (conversion method) is added to the attribute of the structured document. As described above, the text converter 8 converts the still image data that is the main body of the facsimile data into text data. Then, the still image data converted into the text data by the text conversion unit 8 is added to the data extracted and converted as the attribute by the data extraction and conversion unit 6 to create the structured document 10.

The structured document 10 is transferred to the document management server 24, and the information on the communication itself is structured from
The data extraction unit 14 extracts processing conditions, classification search keywords, and the like. From the extracted data, a corresponding processing condition is determined with reference to the data in the processing condition storage unit 16, stored in the storage unit 20, distributed to predetermined clients 26 to 28, and printed out. The non-text conversion unit 18 converts the structured document stored in the storage unit 20 into the original non-character data with reference to the attribute of the conversion condition.

FIG. 3 shows a structuring algorithm of received data, taking the case of FIG. 2 as an example. When facsimile data is received in step 1, information about a communication path including the own device and information about a communication method are extracted. The information on the communication path includes the number of the receiving device, the communication time, the reception date and time, the communication result, the source number, the sub address of the source, and the like. The information on the communication method includes the resolution of facsimile data, the encoding method, the size of paper, and the like (step 2). Next, by referring to the structuring condition table stored in the processing condition storage unit, the extracted information to be used as it is as an attribute, the converted information to be attributed, and the discarded part are determined, and the information to be structured is determined. Attach appropriate tags.
Further, the transfer destination of the structured document is determined (step 3). Next, the still image data is converted into text data, and the used conversion data (conversion method) is added to the attribute (step 4). Then, the structured document is transferred, and the data used for structuring, the transfer destination, and the transfer result are stored (step 5).

FIG. 4 schematically shows the relationship between the structured document generation device 2 and the structured document processing device 12 in FIG. If the text data or structured document side is the upper layer and the non-character data side is the lower layer, the structured document generation device 2
Receives the still image data 40 and the information 42 on the communication itself regarding the communication path and the communication method. Then, data is extracted from the information related to the communication itself, a part of the data is converted into a keyword or the like by the data conversion unit 44, and a structuring unit 46 adds a tag or the like to structure the data. In addition to this, the conversion method for converting the still image data into text is structured by attaching a tag or the like. Further, the still image data is converted into text data by the text conversion unit 8 and structured by attaching a tag or the like. The combination of these is the structured document file 10.

The structured document file 10 is transferred to the structured document processing apparatus 12, and the processing conditions are determined by the data extracting unit 14, or keywords for storage and retrieval are extracted, and the processing conditions are stored in accordance with the extracted data. The processing / processing conditions are determined by the unit 16. When processing is performed by restoring to non-character data, the non-text data is restored to still image data or the like by the non-text converter 18 and the processing unit 48 performs predetermined processing and outputs the processed data. When the text data is processed as it is, the data is similarly processed and output by the processing unit 48. The processing includes storing in a storage unit under predetermined conditions, transferring to a predetermined client, creating a database using information related to communication itself, and restoring to still image data, etc. Or combining the extracted keyword with the still image data and displaying it.

FIG. 5 shows an example in which TIFF data is structured according to the XML standard. The upper left side of FIG. 5 shows TIFF data, and BASE is used as a text conversion method for still image data.
64, and is converted into text data. Other methods of text conversion of still image data include BinHex, u
uencode and the like. The original data was in TIFF format, the TIFF data was converted to text data by BASE64, and information obtained from the communication itself was attributed as a keyword. Describe the image data.

The operation and effect of the embodiment will be described. In the embodiment, data that is not originally suitable for a structured document, such as facsimile data, moving image data, and audio data, can be converted into a structured document. Keywords for performing processing, management, and the like of the structured document can be extracted and converted from information related to the communication itself, so that these keywords can be automatically generated. For this reason, the structured document can be managed without interpreting the meaning of the non-character data itself or extracting features. In the structured document, the non-character data is converted into text data to be a part of the structured document, so that the management becomes easy unlike the case where the file is attached to another file. If information relating to the communication itself is extracted and converted into a keyword, the meaning and content of the data can be specified to a considerable extent from the source, the date and time of the communication, the type of data, and the like. In addition, if simple data such as data sent by facsimile from a certain source is a design document can be freely input to the extraction and conversion unit,
The content of the document itself can be identified to a large extent. Further, if attributes such as the date and time at the time of image scanning, the condition, the number of copies, the user name, the title of the file, and the like, the content of the structured document can be specified. Then, since the conversion condition from the text data to the non-character data is described in the structured document, the original non-character data can be restored if necessary.
