2. Description of the Related Art As a known document describing the prior art relating to the present invention, for example, "text abstraction device" in Japanese Patent Laid-Open No. 61-117658 or Japanese Patent Laid-Open No. 2-11206.
There is a "text simple display method" in Japanese Patent No. 8 publication. JP-A-6
According to Japanese Patent Laid-Open No. 1-117658, a summary of sentences is useful when quickly reading a large amount of documents, and for this reason, the summary is automatically generated. With current technology, the summarization is not well-suited and important parts are likely to be missing.

On the other hand, in Japanese Patent Laid-Open No. 2-112068, the intermediate language format of a text is identified as an essential constituent element and an optional constituent element, and only a character string corresponding to the essential constituent element is used, which is different from the original document. In addition to displaying a short abbreviated document, the original document is displayed in conjunction with the abbreviated document display,
By displaying a character string corresponding to an essential component as a character string corresponding to another optional element and displaying the character string, a missing part of an important portion is complemented, and the latter identification display has an effect of speed reading. In the invention described in this publication, it is considered that the essential constituent elements in the identified intermediate language form correspond to the verb of the predicate of the main sentence and its essential case pattern.

Further, the previously proposed Japanese Patent Application No. 3-34967.
No. 6 “Document speed reading support display system and document processing device and document retrieval device” is for a character string to be emphasized in a document,
For the character strings of other parts, the size of the characters is reduced, and the characters to be reduced are displayed or printed at the same position as the original text.The emphasized part or other parts are the character type, specific word, specific part of speech. The key word is emphasized by making a decision. Further, the previously proposed Japanese Patent Application No. 5-66048, “Document Display Device, Document Summarizing Device, and Digital Copying Device” focuses on the words included in the heading portion in the display for a document consisting of the heading portion and the text. , And identifies and displays the relevant word portion in the text and a sentence including the relevant word.

[0005]

[Purpose] The present invention has been made in view of the above situation, and it is effective to identify and display a specific portion in order to quickly read a large amount of documents. The parts that are suitable for are not limited to the essential components and keywords, so phrases that are suitable for following the flow of sentences are extracted, and phrases for reading such as the subject and new information presentation are extracted. In the identification display, the non-emphasized portion complements the information loss, but in some cases, the non-emphasized portion is annoying and difficult to read. Therefore, by providing a document speed reading support display device, a document processing device and a digital copying device that complements the information loss of the non-emphasized part by displaying only the emphasized part and making it easy to return to the original text immediately when necessary. To do It has been made for the purpose of.

It has an identification display / printing means 2, and the specific portion extracting means 1 identifies a portion suitable for speed reading of a document.

FIG. 2 is a diagram showing another embodiment (claims 2, 3, 4, and 5) of the document speed reading assistance display device according to the present invention.
In the figure, 3 is a sentence analysis means, and other parts having the same operations as in FIG. 1 are given the same reference numerals. Claims 2, 3, 4
2 is another embodiment of claim 1, and as shown in FIG. 2, a sentence analyzing means 3 is further added to the specific portion extracting means 1 of claim 1, and a syntactic structure obtained by the sentence analyzing means 3 is also added. And a phrase suitable for following the flow of sentences (Claim 2), an important phrase in reading such as a subject or new information presentation (Claims 3 and 4).
Is extracted, and the extracted phrase is identified and displayed or printed.

Hereinafter, the sentence analysis means 3 has already been used in a source language sentence analysis unit such as a machine translation system. In the present invention, the language of the document is not specified, but in the following description, a Japanese document is shown as an example. The syntactic structure obtained by the sentence analysis means used in the embodiment will be described below. As a result of sentence analysis for the following example sentence 1 “delivering a message to a designated party at a designated time”, it is possible to obtain syntax structure information as shown in the following Table 1 (as the syntax structure, There are various types, but here we have a form that represents the dependency structure of the clause.

[0010]

[Table 1]

Here, each line shows information in units of phrases. Taking the third line as an example, “[3]” indicates a clause number, and “[designated {sahen noun} sa {saheno tail = un}} {rel = use} {ta = body}]” , The composition of words in a phrase is indicated by a pair of notation (“designation” or “sa” etc.) and a part of speech (“Sahen noun” or “Sahen ending = not yet”) shown in “{}”. "{Verb phrase union form union}" indicates a sequence of information indicating the attribute of the bunsetsu, and "→ [4]" indicates the bunsetsu number to which the bunsetsu is modified. Note: Regarding the part of speech, "not" after "="
And "for" are "pre-forms" and "consecutive forms", "lower la" in front of "=" is an abbreviation for "la line lower one-stage verb", and if "upper" or "five" It is an abbreviation for "Ka line first stage verb" and "Sa line five stage verb". In addition, the katakana string before “=” indicates the final form of the functional word to be used, for example,
“Rel” means “auxiliary verb“ ru ”.” “Delivery” etc. before “:” means the final form of the independent word to be used.

According to the information on the destination of the clause modification, the dependency structure tree of the clause as shown in Table 2 below can be obtained.

[0013]

[Table 2]

Further, according to the information on the destination of the clause modification, the clause number that modifies the clause can be easily obtained as shown in Table 3 below.

[0015]

[Table 3]

Next, claim 2 will be described. It has sentence analysis means 3 for analyzing the sentence of the language of the target document to obtain a syntactic structure, and the specific part extraction means 1 uses the syntactic structure by the sentence analysis means 3 to determine the head element of the syntactic structure and the predicate modifier. A predicate element and a noun element that modifies the noun modifier predicate element and the noun element that modifies the predicate element, and a formal noun element and an element that modifies the formal noun element; Some or all of the elements that directly modify the above elements are extracted.

That is, according to claim 2, as a phrase suitable for following the flow of a sentence, a1. Head element of syntactic structure, b1. A predicate element of predicate modifier, b2. A noun modifier predicate element modified by the predescriptor modifier predicate element (b1), b3. A noun element modified by the noun modifier predicate element (b2), c1. A formal noun element, c2. An element that modifies the formal noun element (c1), d. Part or all of the elements that directly modify the elements shown in the above sections are extracted as the specific part.

The respective terms of claim 2 have the following meanings. a1: It is the top of the sentence syntactic structure. b1: Corresponding to a part of "... shi (te)" of "... shi, ... shi, ...", and tracing a continuous predicate. b2: Corresponding to the "-do" part of "...- do ...- do ... do ...", which corresponds to the ending part of a continuous predicate. b3: Corresponds to the noun phrase portion "..." That is modified by the above-mentioned continuous predicates. c1: This is a phrase that receives an abstract concept, such as "koto" or the semi-positional particle "no". c2: It corresponds to the head part of the above abstract concept. d: A part that supplements a predicate element or the like, such as "ga" or "to" for "do" in "... ~ ga ... ... do".

These can be extracted as follows, for example. ． All clauses are sequentially examined, the (clause) element of the next condition is extracted, and marks (a1, b1, c1) are added. a1: A clause whose destination is empty. b1: The bunsetsu attribute is "verb phrase", "adjective phrase" or "copula phrase", and it is "usual adjective" or "te-usual". c1: "bunsetsu attribute" is "formal noun phrase" or "quasi-form phrase" ,. Subsequently, all clauses are sequentially examined, the (clause) element of the next condition is extracted, and the marks (b2, c2) are added. b2: a noun element which is modified to a bunsetsu marked with b1 and which is modified by the predicate element of the noun modifying property, and a bunsetsu attribute is a "verb phrase", an "adjective phrase" or a "copula phrase", and a "adnominal form union" The phrase that is ". c2: A clause that modifies a clause marked with c1.

[0020]. Subsequently, all clauses are sequentially examined, the (clause) element of the next condition is extracted, and the mark (b3) is added. b3: A phrase modified to a phrase marked with b2 and having a phrase attribute of "noun phrase". ． Subsequently, all clauses are sequentially examined, the (clause) element of the next condition is extracted, and the mark (d) is added. d: a clause that modifies a clause marked with a1, b1, b2, b3, c1, c2.

Although the bunsetsu attribute is used as a condition, the bunsetsu attribute is obtained by the sentence analysis means from the word structure of the bunsetsu in order to recognize the modification destination of the bunsetsu, and especially for the present invention. Not set. The clause attribute that appears above is
It is given for the clauses shown in Table 4 below.

[0022]

[Table 4]

Assuming that the phrase marked by the above process is extracted as the specific part, finally ,. All the clauses are sequentially examined, and the notation of the clauses is obtained from the notation of the words that compose each clause, and according to the marked clauses or other clauses, they are identified and displayed or printed out.

When selecting an element to be extracted, a part of the above processes (1) to (4) may be skipped or the corresponding mark may be ignored. Note that the process from extraction to display / printing (-) can be performed in one scan for all clauses, but for the sake of simplicity of explanation, a plurality of scans were performed. In the above-mentioned example sentence 1, the first scan is marked with "a1" and "c1" in the phrase "koto", and the second scan modifies "koto" of "c1". The phrase "deliver" is marked with "c2" .- No mark is attached in the third scan.-In the fourth scan, "to the other party" that modifies "deliver" of "c2". , "At time", "message" clauses are marked with "d". Next, in the final scan, highlight the marked clauses,
This is an example in which identification is displayed as shown in Table 5.

[0025]

[Table 5]

FIGS. 3 to 6 (a) and 6 (b) show an example sentence 2 (published patent publication), its dependent structure information, a dependent structure tree, and an example of identification display according to this method. Note that FIG. 6B is an example in which the specific portion is displayed normally and the other portions are displayed in a reduced size so that the specific portion is highlighted.

Next, claims 3 and 4 will be described. In claim 3, based on the syntactic structure, as an important phrase in reading such as the subject or new information presentation, h1. Elements leading by the particle "ha", g1. Either or both of the elements led by the case particle "ga" in the main sentence are extracted as the specific part. In claim 4,
Further, h2. The main sentence or the main element in the sentence including the element led by the particle "ha" g2. Some or all of the entire main sentence or the main elements in the sentence including the element guided by the case particle "ga" in the main sentence are extracted as the specific part.

Each of the terms h1 and g1 in claim 3 is usually
The particle "ha" indicates the subject, and the case particle "ga" in the main sentence corresponds to the function of guiding new information (unknown). Example sentence 3 below
Then, I will briefly explain the functions of "ha" and "ga". "Once upon a time, there were an old man and an old woman . The old man went to the mountain to Shibakari. The old woman went to wash the river. <br/> When the old woman was washing in the river, a big peach was found. It started flowing with Dombri Codon Brico. "

In the first sentence, "grandfather and grandmother" having new information is introduced by "ga", and in the second sentence and the third sentence, respectively.
Of the known information, "grandfather" and "grandmother" are taken up and explained, and in the fourth sentence, the new information "big peach" is introduced again. These thematic phrases and new information phrases are extremely important in terms of the function of language communication, and identifying and displaying them is useful for speed reading and reading comprehension.

The clauses "h1" and "g1" in claim 3 are:
First, h1: a phrase including a particle "ha" in a phrase, g1: a phrase including a case particle "ga" in a phrase and whose modification destination is a head element are extracted ("the modification of" g1 " The phrase "head is the head element" requires that it is a phrase in the main sentence. Furthermore, for each, all the subordinate phrases in the dependency structure are extracted. Once the phrase to be modified is obtained, it can be easily obtained by recursively obtaining the lower-level phrase, for example, the phrase “[2,4,5]” that modifies the phrase “[6]” in the example sentence 1. However, if the clauses that modify these are recursively obtained, the clause "[1, 2, 3, 4, 5]" under "[6]" is finally obtained.

Since claim 4 is the entire sentence including the above clause or its main elements, if the former includes the above clause, all clauses may be extracted, and the latter may be the same as in claim 2. Can be obtained by combining with extraction. However, "g2"
As for, the clause of the main sentence may be a clause obtained by removing the clause of the head of the subordinate sentence and the clauses under it from the whole clause. The head of the subordinate sentence modifies the head element and is a clause of the following condition.・ The phrase attribute is "conjunctive form" or ・ The word at the end of the phrase is "connective particle". 7 and 8 show examples of identification display in Example sentence 4 and claim 3.

Next, claims 5 and 6 will be described. The identification display that emphasizes a specific portion may hinder speed reading even if other portions are not emphasized. In contrast,
For an invention in which a particular character string in a document to be emphasized is displayed normally, and for the character strings of other parts, the character whose size is reduced is displayed at the same position as the original text. No. 3-349676, "Document Speed Reading Support Display System, Document Processing Device and Document Retrieval Device"
However, this alleviates the above-mentioned adverse effects.

According to the fifth aspect, on the assumption that the original document is displayed, other parts are hidden and only a specific part is displayed while maintaining the same positional relationship as that. As a result, if the user wants to return to the corresponding portion of the original sentence while eliminating the above-mentioned adverse effects and improving the effect of speed reading, it can immediately return because the same positional relationship is maintained. In addition, the hidden character string is a character string to be hidden and has a space or dot (“.”) Equal to its length.
You can replace with.

According to a sixth aspect, the specific portion identifying display / printing means 2 displays or prints the original document together.
That is, it is paired with the display of the original document. Figure 9
(A), (b) is a figure which shows the example of a display in Claim 5, 6 of an example sentence. FIG. 9A shows an example in which a keyword-like word is used as the specific portion. Keywords-like words are extracted by a simple method based on character types such as a kanji string of three or more characters and a katakana string.

Next, claims 7 and 8 will be described. A seventh aspect is an embodiment in which the document speed reading support display device according to the present invention is applied to a document processing device. FIG. 10 is a block diagram of a digital copying apparatus according to the present invention (claim 8), which is an embodiment in which the document speed reading support display apparatus according to the present invention is applied to a digital copying apparatus having a character recognition function. 11 in the figure

2 reads an image as digital image data. The output means 16 outputs the digital image data obtained by the image data reading means 12 and its processed data. The character recognition means 13 recognizes characters from the document digital image data read by the image data reading means 12. The character data processing unit 14 processes the document data digitized by the character recognition unit 13 based on part or all of the document speed reading support display device according to the first to sixth aspects. The document speed reading support means 15 includes the document speed reading support display device according to any one of claims 1 to 6.
