Abstract

PURPOSE:To execute such a display, etc., as it is easy to follow and read an important part the original containing other part than the important part can be read immediately by leaving size of a character of the important part to be emphasized as standard size, and making character size of other part than the important part small. CONSTITUTION:In a step 1, in the beginning, the device is set to a standard mode in advance, and in a step 2, a digit number counter for line feed control of one line is initialized to '0' in advance. In a step 3, thereafter, a character of a document is read in by one character each, and in steps 4-6, the following processings are repeated, and when the character is gone, the processing is finished. In the main processing, the kind of a character is decided, and in the case of KANA (Japanese syllabary), the device is set to a 1/4 fold mode in a step 7, and thereafter, in a step 9, a half size null, the KANA concerned, and a half size null are outputted continuously. In this regard, when the device becomes a 1/4 fold mode already, a mode change is unnecessary and the processing advances to a step 8. Also, in the case of being other than the KANA, the device becomes the standard mode in a step 10, and thereafter, in a step 12, the character concerned is outputted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic document display system, and more particularly to a document speed reading support display system, a document processing device and a document search device. For example, it is generally applied to a document processing device such as a document editing device, a document browsing device, a document search device, etc., which needs a function of displaying or printing a document.

[0002]

2. Description of the Related Art When creating or providing a document, emphasizing important parts is an effective support for those who view it. Specifically, when displaying or printing a document,
Underlines, shades, reverses, and enlarges important parts. However, for this purpose, it is generally necessary to manually process important parts in advance. On the other hand, in many cases, a document search device or the like has a function of automatically searching for a specified word or a related word in a document and displaying the part by the above method. For example, there is the Peace Information Center: "Important Keyword Extraction System" pamphlet. As a derivative function of the English-Japanese machine translation system, only the translations of important words are displayed in correspondence with the original English sentence display, and speed reading of English sentences is supported, for example, Suzuki et al., Sharp: "Machine translation system DUET E / J II Current status and future issues ”(English speed reading support, Information Processing Society of Japan Natural Language Processing Research Material 84-16, P.125 (pp.119-116), 1991; no display example). Further, in Japanese Unexamined Patent Publication No. 2-112068 “Text Simplified Display Method”, syntax analysis is used to
Create short sentences using only the essential elements of the sentence to support speed reading. Here, in addition to displaying only the short sentences, as an example of displaying only the character strings that are the elements of the short sentences in the original text by distinguishing them from other character strings, An example of displaying in small size characters is given [Fig. 12 of the reference].

Of the above, in searching for references, it is necessary to specify in advance the necessary words (keywords).
Then, the important part to be traced is automatically extracted. Therefore, an unknown document can be efficiently browsed without human intervention in advance. When viewing a large amount of documents, such highlighting is effective, and it is considered that important reading is performed when reading a so-called oblique reading (flow reading) or a speed reading.

As described above, in general, important parts must be processed in advance, and the search device must prepare a specific word (keyword) to be searched in advance.
The method is superior in that it automatically extracts important parts. However, there are the following problems. (1) In these displays, only the important parts are displayed. In actual speed reading, this becomes a problem when reading other parts than important parts as necessary. On the other hand, in the general underline or reverse display format, the original text can always be followed, but a) important parts are emphasized more than necessary,
Since it is a normal display except for the important part b), it is relatively easy to get into the eyes, and as a result, it is easy to hinder the natural tracking of the emphasized part. In this respect, the method of changing the size of the characters, which is supplementarily shown in the above, is effective for b). However, the problem of a) remains, and the burden of browsing due to poor display balance with respect to the original text may be considered. (2) Since a costly technique called syntactic analysis is used to search for an important part, it is difficult to realize.

[0005]

[Purpose] The present invention has been made in view of the above-mentioned circumstances, and in order to efficiently browse a document, it is easy to trace the important part and read the important part as necessary. Display or print the original text including the text in a more organized format so as to reduce the burden of browsing, and do not need to process important parts in advance, and the cost is relatively low. It is an object of the present invention to provide a document speed reading support display system in which an important part is automatically detected by, and a document processing device and a document search device having the display system.

[0006]

In order to achieve the above object, the present invention provides (1)
In a document display method that displays or prints a digitized document, the character size of the character string of the other part is reduced with respect to the character string to be emphasized in the document, and the reduced character is placed at the same position as the original text. It has a function of displaying or printing, (2) Judgment of a part to be emphasized or other parts in the document by a character type, and (3) Word other than the part to be emphasized in the document. Or judging by a character string, further,
(4) A part to be emphasized or other part in the document is determined by the part of speech of the word, or (5) a document processing device using the document speed reading support display method described in (2) to (4) above. Or (6) a document display method for displaying or printing a document including a searched word portion, which has a function of searching a specific word in an electronic document or a word related thereto , Uses a document speed reading support display method characterized by reducing the character size of words other than searched words in a document and displaying or printing the reduced characters at the same position as the original text. The present invention is characterized in that it provides a document retrieval device that has been used. Hereinafter, description will be given based on examples of the present invention.

First, the invention described in claim 1 will be described. In order to efficiently browse the document, it is easy to read the important parts and read or print the original text including the non-important parts immediately if necessary so that the burden of reading is reduced. , In order to carry out in a more organized format, the size of the characters of the important part to be emphasized remains the standard, and the important part is indirectly emphasized by reducing the size of the characters of the parts other than the important part. However, the character position of the original sentence is retained in order to avoid the difficulty of seeing due to the increase of the character density due to the reduction. Note that FIG. 1 shows a display example of the original text.

In the following, in the embodiment, the size of the character to be reduced is set to 1/2 each of the vertical and width (1/4 in area) with respect to the standard character, and the positional relationship with the original sentence is maintained. In order to do that, we will show the display form in which the front and back of the character are sandwiched by white space with a width of 1/4. However, in the present invention, the reduction ratio and the ratio of blank spaces to be embedded are not limited to this. In addition, although Japanese documents are shown in the examples,
The present invention is not limited to Japanese. In addition, here, there are standard mode and 1/4 times (vertical and width each 1/2, area 1/4) mode as control for display or printing, and the mode is changed by the corresponding control code. Suppose you can. Also, assume that there are full-width characters and half-width characters.

According to this assumption, for example, when a character string "about a Japanese document" is to be emphasized in "Japanese" and "document", [mark] Japanese [1/4] _ of
By sending the data _ [mark] document [1/4] _ __ _ __ ___ _ _ _ [mark] to the display system and the printing system, the display for the original text as shown in Table 1 below. Alternatively, a print is obtained.

[0010]

[Table 1]

In the above, "[mark]" and "[1/4]" are control codes for the standard mode and the 1/4 times mode, respectively.
_ ',' __ 'are 1 or 2 half-width spaces, and'_' is a half-width space (1/4 of full-width).

In general, the words forming a sentence can be classified into types called content words and function words. The content word is a word indicating an entity or an event such as a noun or a verb, and the functional word is a word such as a particle indicating a relationship between the content words or an auxiliary verb with an attribute of the event. It can be said that the above-mentioned semantically rich portion of information substantially corresponds to the content words. That is, it is considered that the oblique reading (speed reading), which is performed by a human to roughly understand the contents of a large amount of documents, is experientially following this content word. The present invention uses a method of approximating a semantically rich portion (or other portion) to obtain characters of a portion other than the semantically rich portion shown above. Display to reduce the size of. There is a method of not displaying the part other than the part that is semantically rich in information, but it may be necessary to read it in detail as a sentence if necessary, and because it is an approximate method, it can be extracted. There are mistakes, and for these reasons, these parts are not obsolete.

Next, the invention described in claim 2 will be described. A portion other than the portion that is semantically rich in information is approximately determined by the character type. For example, in Japanese, hiragana is used as the character type. That is,
In general Japanese with kana-kanji mixing, functional words such as particles and auxiliary verbs consist of hiragana, and content words such as nouns and verbs consist of or contain kanji and katakana. FIG. 2 shows a display example by this method.

FIG. 11 is a flow chart for explaining the processing of the invention described in claim 2 (in this processing flow, prohibition processing etc. are not shown for simplification). In this process, first set the standard mode (step 1),
Also, the digit counter for line feed control of one line is initialized to 0 (step 2). Thereafter, the characters of the document are read character by character (step 3) and the main processing (steps 4 to 6) below is repeated, but the process ends when there are no more characters. In the main processing, the character type is determined, and if it is a Hiragana character, the mode is set to 1/4 times (Step 7), and then the half-width blank, the Hiragana, and the half-width blank are successively output (Step 9). However, if it is already in 1/4 mode, it is not necessary to change the mode (step 8). If it is other than hiragana, the standard mode is set (step 10) and the character is output (step 12). However, if it is already in standard mode, it is not necessary to change the mode (step 1
1). However, before the above processing, a line feed and a digit counter are zeroed if necessary by comparing the digit counter with the digit designation value in one line (step 5). After the above processing, the digit counter is added (step 13).

When this processing is performed on the document shown in FIG. 1, the hiragana portion as shown in FIG. 2 becomes a reduced character, while a display in which the positional relationship with the original sentence is maintained is obtained. Note that if you do not insert single-byte spaces before and after the hiragana, the positional relationship with the original text is not retained as shown in FIG.
As a result, the display density is high, and the output is difficult to see.

Next, the invention described in claim 3 will be described. A portion other than the portion that is semantically rich in information is approximately determined by a predetermined specific word (character string). For example, in Japanese, "ha", "ga", "ni", which is a particle as this specific word,
"He", "From", etc., and "Minor", etc.,
Adopt "etc.", "other", "other", etc. Hereinafter, an embodiment of claim 3 will be described.

First, as a first step, a search process for a designated word is performed on a document. Since the search process itself for a plurality of character strings can be easily realized as a conventional technique, the details of the process are not shown. Here, as shown in FIG. 7, special marks (in FIG. 7, before and after the searched word)
Insert '[', ']') and expand it once in memory or file. Then, as a second step, when the expanded contents of FIG. 7 are processed according to the processing flow of FIG. 12, the display shown in FIG. 4 is obtained. Steps 1 to 5 are the same as the flowchart of claim 2.

In this processing, each character is read and it is judged whether or not it is a character type (step 6). If '[', the mode is set to 1/4 times (step 7). However, if you are already in 1/4 mode, you do not need to change the mode. If the character type is "]" (step 6), the standard mode is set (step 8). However,
If already in standard mode, no mode change is necessary. If the character type is something other than '[' or ']' ((step
6) In the 1/4 mode (step 9), the half-width blank, the relevant hiragana, and the half-width blank are continuously output (step 10).
In the standard mode (step 9), the character is output (step 11). It should be noted that instead of performing the two-step process for the entire document, it may be performed for each unit of paragraph, “.”, Or “,” (in this case, initialization of the digit counter in the process flow). Will be handled slightly differently, but it is not essential so I won't discuss it here). The control of line feed is the same as in claim 1.

Next, the invention described in claim 4 will be described. The part other than the part that is semantically rich in information is approximately determined by the word of a predetermined specific part of speech. For example, in Japanese, the specific parts of speech include nouns, verbs / adjectives / adjectives, stems, adverbs,
A part-of-speech (referred to as type B) that is not any of the symbols (referred to as type A here) is adopted. Hereinafter, an embodiment of claim 4 will be described.

First, as the first step, morphological analysis (word segmentation) processing is performed on the document. Since the morphological analysis process itself can be easily realized as a conventional technique, its processing content is not shown. Here, the results shown in FIGS. 9 and 10 are obtained, and the results are once expanded in the memory or file. 9 and 10 are records for each word, and each record includes position information (the number of characters from the beginning), words, and part-of-speech information. Then, as a second step, when the developed contents of FIGS. 9 and 10 are processed according to the processing flow of FIG. 13, the display shown in FIG. 5 is obtained.

In this processing, the processing for each word record is advanced (steps 1 to 3), and the processing ends when there are no more word records. In the processing for each word record, the part of speech is determined (step
4) If the type is B, the 1/4 mode is set (step 5). However, if it is already in 1/4 mode, it is not necessary to change the mode (step 6). If the type is A, the standard mode is set (step 7). However, if it is already in the standard mode, it is not necessary to change the mode (step 8). Then, the characters of the words in the word record are sequentially read (step 9), and the next process is repeated (steps 10 and 11). When the characters are used up, the processing for each word record ends. In the 1/4 mode (step 12), the half-width blank, the relevant hiragana, and the half-width blank are successively output (steps 13 and 14). In the standard mode (step 12), the character is output (step 15). In addition,
Similar to the second aspect, the process of two steps may not be performed for the entire one document, but may be performed for each unit of paragraph, “.”, Or “,”. The control of line feed is the same as in claim 1.

Next, the invention described in claim 5 will be described. In a conventional document processing apparatus having a display or printing function, it can be easily realized by adding the above-described processing.

Next, the invention described in claim 6 will be described. By displaying the document including the search word in the document search device or the like, the search word is treated as the above-mentioned semantically rich portion. This realization is in principle the same as the method according to claim 2. Here, an example is shown in which keywords related to the information processing field (“information”, “computer”, etc.) are searched. Similarly to claim 2, the first
As a step, as shown in FIG. 8, a result in which a special mark ('[', ']') is added before and after the searched word is obtained, and thereafter, the processing flow of claim 2 is obtained. (Fig. 1
FIG. 6 is obtained by the processing in which the treatment of the 1/4 mode and the standard mode of 1) is reversed.

[0024]

[Effect] As is apparent from the above description, the present invention has the following effects. (1) Effect corresponding to claim 1: By reducing the size of the characters other than the important portion to be emphasized, the important portion is indirectly emphasized, and the indirectly emphasized portion is traced Support the efficient reading of documents (oblique reading, flow reading, speed reading) while grasping the flow. Furthermore, if necessary, it is possible to re-read the detailed portion, including the reduced portion, so that accurate reading is possible. In this display, the characters of the important part are kept in the standard size, the non-important part is reduced, and the important part is indirectly emphasized. This is more suitable for speed reading than the conventional display, because important parts are not emphasized more than necessary and non-important parts do not get into the eyes naturally. Furthermore, since the positional relationship with the original text is maintained, it is easy to correspond to the original text. Further, according to claims 2 to 4, processing on the document is not required in advance, which is advantageous for browsing an unknown document. In addition to the above, claims 2 to 4 have the following effects. (2) Effect corresponding to claim 2: Since only the part to be reduced is determined by the character type, preparation of a dictionary and specific words is not required, and processing is simple, so that it can be realized very easily. (3) Effect corresponding to claim 3: Since the part to be reduced is determined only by a predetermined word, a dictionary is unnecessary and the determination of the part to be reduced is more correct than in claim 1. For example, the hiragana noun "ambiguity" reduced in claim 2 is not reduced. (4) Effect corresponding to claim 4: Since the portion to be reduced can be other than the so-called content word, the determination of the portion to be reduced is more correct than in claims 1 and 2. For example,
Similar to claim 3, the noun consisting of the hiragana word "ambiguity" reduced in claim 2 can be left unreduced, or an auxiliary verb that is difficult to reduce because it is used in claim 3. Can be reduced. A morphological analysis process that realizes this requires a dictionary, but it can be introduced at a lower cost than the syntax analysis technique.
