Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document display device, and more particularly to general information equipment for handling documents (including a printing device).
The present invention relates to a document display device having information presenting means using the visual sense of the user.

[0002]

2. Description of the Related Art Many of the display means of document processing apparatuses that are widely used at present have a plurality of display forms depending on attributes such as presence / absence of underline, font and color for each character. Although it should be possible to reduce the effort for the user to understand the document if it is switched according to the document, the display form can be switched by the control characters embedded in the document data or the switch switching by the user. There is. Regarding the important word detector, for example, Japanese Patent Publication No. 57-21720 discloses a system for detecting a keyword in a continuous language by utilizing a continuous asynchronous correlation operation. In addition, by storing unnecessary extraction character strings in an unnecessary word file, removing unnecessary words in sentences by referring to the file, and extracting keywords, the extraction process is simplified and the processing time is shortened. It is also known to process Japanese sentence data at high speed.

Further, it is also known that a memory is provided with a dictionary table accommodating unsuitable words as keywords for each field so that words most suitable for a document to be registered can be displayed as keywords in order of appearance frequency in the document. Has been. Further, it is also known that a keyword can be searched for in an emphasized section in a sentence so that the amount of calculation can be reduced and the keyword can be searched efficiently. Further, as previously proposed, there is a "document display device" that automatically determines the document type and switches the display form for the entire document. Also, an important word detector has been proposed.

When embedding a display type switching control character inside the document data, the creator is required to perform extra work when the document is created, and when the user switches the switch, the user performs extra work. If you do not do any of the above, and the display form is constant regardless of the nature of the document, the individuality of the document will be buried, and the effort for the user to understand the document can be reduced. There was a problem that it could not be done. Particularly, since the important words and the unimportant words are not displayed in different display forms, there is a problem that the user cannot understand the contents of the displayed document unless he or she carefully looks at the displayed document. Further, for example, even when considering a document dividing unit that divides an input document into important words and unimportant words, what kind of words are important is different for each document type. Therefore, it is not appropriate to use the common document dividing means regardless of the document type.

Next, regarding the discrimination of the document type, depending on the editing system, the editing mode may be switched according to the document type designation command embedded in the document or the document name. (Example: In emacs, "-*-" is added to the first non-blank line.
If the character string "C-*-" is included, or if the document name ends with .c or .h in the first non-blank line and no type is specified, the C program edit mode is set ("GNU Emac
s Manual ”Chapter 18)).

Regarding the discrimination of the document type, when the type designation command is embedded in the document, the document creator is still required to perform extra work. In addition to being required to manage the names consciously, there is a problem that the discrimination by this method is invalid at the time of new creation without assigning a document name.

[0007]

[Object] The present invention has been made in view of the above-mentioned circumstances, and reduces an effort to understand a document by displaying important phrases and insignificant phrases in different display forms. The type is determined, the type is determined in parallel with the document creation even when a new document name is not assigned yet, and the document dividing means is switched according to the document type to flexibly handle various documents. The object is to provide a corresponding document display device.

[0008]

In order to achieve the above object, the present invention provides (1)
Document input means for inputting document data, document dividing means for dividing the document input by the document input means into several parts having different characteristics, and a plurality of display forms depending on the attribute for each character are provided. A display output means capable of selecting and using for each character a plurality of display forms possessed at the time of display, and a display of the characters included in the portion of the input document divided by the document dividing means according to the nature of each portion. Selecting a shape and controlling the display output means, automatically selecting a display shape to be used according to the property of each part of the input document, and (2) the document dividing means. In the above, there is provided an important word detecting means for detecting an important word from the input document, and the input document is divided into an important word and an unimportant word, or (3) a document input means for inputting document data, The A document type discriminating means for discriminating the type of the document input by the handwriting inputting means, and a plurality of display types for each character having different attributes can be selected and used for display. The display / output means and the control means for controlling the display / output means by selecting a display form according to the input document type determined by the document type determination means are used automatically according to the type of the input document. And (4) the document type discrimination means collates the fixed pattern pattern storage unit for storing the fixed pattern pattern of the document and the document fixed pattern pattern stored in the fixed pattern pattern storage unit with the input document. A fixed pattern detection unit including a pattern matching unit and a control unit, a type-corresponding vocabulary storage unit that stores the correspondence between a vocabulary and a document type, a morphological analysis unit, and And at least one of a type-corresponding vocabulary detection unit including a collating unit and a control unit for collating the data stored in the type-corresponding vocabulary storage unit, and at least one of the detected fixed pattern and the type-corresponding vocabulary. Determine the type of input document using
Alternatively, (5) document input means for inputting document data,
A document type discriminating means for discriminating the type of the document input by the document inputting means, a document dividing means for dividing the document input by the document inputting means into several parts having different properties, and the document type discriminating means. The selecting means for selecting the document dividing means according to the document type determined by the above, and the plural display shapes which have plural display shapes depending on the attribute for each character and which are held at the time of display are selected for each character. Display output means that can be used as the display output means, and the display output means by selecting the display form of the characters included in the portion of the input document divided by the document dividing means selected by the selecting means according to the property of each portion. It is characterized by having a control means for controlling and automatically selecting a display form to be used in accordance with the property of each part of the input document. Hereinafter, description will be given based on examples of the present invention.

FIG. 1 is a block diagram for explaining an embodiment of a document display device according to the present invention. In the figure, 1 is a document input means, 2 is a document dividing means, 3 is a display output means, and 4 is a control. It is a means. Input the document data by the document input means 1,
The document inputted by the document dividing means 2 is divided into several parts having different properties. The display output means 3 has a plurality of display forms depending on attributes such as presence / absence of underline, font, color, and brightness for each character, and selects a plurality of display forms possessed at the time of display for each character. use.
The control means 4 controls the display output means 3 by selecting the display form of the characters contained in the portion of the input document divided by the document dividing means 2 according to the property of each portion.

That is, the document data input by the document input means 1 in FIG. 1 is divided into several parts by the document dividing means 2 and then displayed by the display output means 3. At this time, the display form is selected by the control means 4 so as to correspond to the property of each divided portion of the document. As the selection method, for example, the position in the document is regarded as a property and the background color is changed for each line, or the importance is regarded as a property and a bold word is used for a part of the important phrase. It is conceivable to have a database that holds the correspondence between the and display forms and search it. Even if the document is divided according to position and the background color is changed line by line, the user is less likely to lose track of what is being read, thus reducing the effort for understanding the document.

According to another aspect of the document dividing means of the present invention, the input document is divided into an important word portion and an insignificant word portion, and the input document is an important word portion detected by the important word detector and other portions. Split into and. Although a conventional important word detector is used, the performance of this document segmentation means depends largely on the nature of the important word detector. If this dividing means is used in the document display device according to claim 1 and the important words are emphasized and displayed, the user can read the document after knowing the important points in advance, and can read only the important words diagonally. However, since the outline of the document content can be grasped, the labor of the user for understanding the document content can be particularly reduced.
As the document dividing means, in addition to the one described in claim 2,
A simple one in which the position in the document is regarded as a property and the document is divided according to the position may be considered.

FIG. 2 is a diagram showing another embodiment of the document display device according to the present invention. In the figure, 11 is a document input means, 12 is a document type discrimination means, 13 is a display output means, and 14 is a control means. is there. The document input unit 11 inputs the document data, and the document type determination unit 12 determines the type of the input document. The display output means 13 has a plurality of display forms depending on attributes such as presence / absence of underline / font / color / brightness for each character, and selects and uses a plurality of display forms held at the time of display. The control unit 14 controls the display output unit 13 by selecting a display form according to the input document type determined by the document type determination unit 12.

That is, the document data input by the document input means 11 in FIG. 2 is used for the document type by the document type determination means 12, and then displayed by the display output means 13.
At this time, the display form selected by the control means 14 corresponds to the discrimination result by the document type discrimination means 12.
As a selection method, for example, the program is displayed in a fixed width typewriter font,
It has a database that holds correspondences between document types and display forms, such as displaying in non-fixed width fonts such as roman font, or displaying handwritten fonts in documents that are written in Japanese colloquial language. It may be possible to search for it. An example corresponding to claim 4 of the processing in the document type discriminating means will be given below, but as for claim 3, this may be a simple one for discriminating the document type from a conventional document name or the like.

FIG. 3 is a block diagram of the document type discriminating means. In the figure, 15 is a fixed pattern detection unit, 16 is a fixed pattern matching unit, 17 is a fixed pattern storage unit, 18 is a control unit, and 19 is a control unit.
Is a type-corresponding vocabulary detecting unit, 20 is a morpheme analyzing unit, 21 is a type-corresponding vocabulary collating unit, 22 is a type-corresponding vocabulary storage unit, 23,
Reference numeral 24 is a control unit. If the line “conference holding notice” exists in the document in the fixed pattern storage unit 17, the document is a notice holding the conference, or a line starting with “From:” and “T:
If a line starting with "o:" exists, the document is an email or an electronic news article, or if a line starting with "#include" exists, the document is a C program. Correspondences between patterns and document types are stored, and the fixed pattern matching unit 16 matches the fixed patterns with the input document. When the input document is successfully matched with a plurality of standard patterns and the document types corresponding to the standard patterns are not the same, the conflict resolution is not performed by the standard pattern detection unit 15, but is performed by the control unit 24 of the entire document discrimination means. Be done. However, it is sufficiently conceivable to add information for conflict resolution to the data stored in the fixed pattern storage unit 17.

If the type-corresponding vocabulary storage unit 22 has colloquial interjectional particles such as "sa", "na", "ne", and "yo" in the document, the document only needs to be written in colloquial language. The correspondence between the vocabulary and the document type, such as a document, is stored, and the type-corresponding vocabulary collating unit 21 collates the type-corresponding vocabulary with the output of the morphological analysis unit 26. When a conflict occurs, the conflict is resolved by the control unit 24 of the entire document discriminating means, but information for conflict resolution may be added to the data stored in the type-corresponding vocabulary storage unit 22. I think enough.

The control unit 24 of the entire type selection unit discriminates the document type by using the detection results of all of the fixed pattern detection unit 15 and the type-corresponding vocabulary detection unit 19 constituting the type selection unit. . As a method of prioritizing when a conflict occurs, detection of a fixed pattern or vocabulary corresponding to each document type is simply calculated, or stored in the fixed pattern storage unit 17 or the type-corresponding vocabulary storage unit 22. It is conceivable that a weight is added to the data as conflict resolution information and the detection of a fixed pattern or vocabulary corresponding to each document type is counted with a weight. It should be noted that the document type discriminating means may be composed of only one of the fixed pattern detecting unit and the type corresponding vocabulary detecting unit.

As described above, the document type discriminating means and the document dividing means have been described above. Since what word is important differs for each document type, there may be a plurality of document dividing means depending on the degree of importance for each document type. For example, when the input document is a program, the part indicating the function definition or control structure is important, and in the case of a newspaper article or the like, the part indicating 5W1H is important. Assume that the input document is a C language program. The document type discriminating means discriminates the program in the C language from the unique vocabulary. In that case, the document dividing means is, for example, / *
It is possible to divide into 3 parts in the part surrounded by and / *, keywords such as if, for, while, and other parts. If this division means is selected for a C language program by the document division selection means, the program is divided into comments, keywords, and others. For example, comments are italic, keywords are bold, and the others are typed. Readability can be increased by displaying in a writer font.

[0018]

As is apparent from the above description, the present invention has the following effects. (1) Effects corresponding to claims 1 and 3; The labor for the user to understand the document can be reduced without requiring extra work for the document creator and the user. (2) Effect corresponding to claim 2; The labor for the user to understand the document can be particularly reduced. (3) Effect corresponding to claim 4; The document creator can determine the document type without requesting extra work. In addition, when creating a new document that has not been given a document name, the type determination can be performed in parallel with the document creation. (4) Effect corresponding to claim 5: Since the document dividing means is switched according to the document type to flexibly deal with various documents, it is possible to display the readability so as to increase the readability.
