Description

The present invention relates to an electronic device used when browsing electronic documents and a method of displaying electronic document data.

In industry, the demand and supply of electronic documents are increasing day by day. Examples of electronic documents include papers and electronic books published on the Internet. Patent publications such as this specification are one example. Moreover, even when the data is finally printed on paper, it is often electronic data in the elaboration stage.

On the other hand, demand for reading electronic documents at high speed is increasing day by day. With the spread of electronic devices such as smartphones, electronic documents can be read anytime and anywhere.

When people read text, they move their eyeballs up, down, left, and right. In order to read documents faster, there is a speed reading method that trains the muscles used for eye movement.

However, training these muscles is not easy. Furthermore, in the case of an electronic document, the display device emits light, which tends to tire the eyes as compared to a paper book. Fatigue accumulates even with trained eyeballs and can impair reading speed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and it is an object of the present invention to reduce eye strain when reading electronic documents and to improve a reader's reading speed.

The electronic document browsing electronic device 10 of the present invention has the following. That is, the character string data input device 12 for inputting the first character string data 12x;
a syntactic analysis device 14 for parsing the first character string data 12x and outputting second character string data 14x divided into units of noun phrases replaceable by demonstrative pronouns and others;
a display device 16 for sequentially displaying the second character string data 14x from the front;
is.

Further, the method for displaying electronic document data according to the present invention has the following steps. i.e.
inputting first string data 12x;
parsing the first character string data 12x and outputting second character string data 14x divided into units of noun phrases replaceable by demonstrative pronouns and others;
a step of sequentially showing the second character string data 14x from the front;
is.

Here, a noun phrase refers to a unit that can be replaced by a demonstrative pronoun.

By dividing the documents and displaying them sequentially, eye movement is eliminated and fatigue is reduced. Therefore, you can concentrate on reading.

Furthermore, since the text of the document is syntactically analyzed in advance and the part of the document is sequentially displayed in units of noun phrases, it is possible to save the trouble of combining the displayed part with the currently displayed part. As a result, the fatigue of the brain is reduced, and the user can concentrate on reading.

FIG. 1 is a representative diagram that best represents the features of the present invention, in which the present invention is applied to a certain Japanese sentence. FIG. 2 is a diagram showing the constituent elements of the present invention together with the process flow of the present invention. FIG. 3 shows the application of the prior art in the area of the present invention to the Japanese text.

EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated in detail.

First, the character string data input device 12 for inputting the first character string data 12x to the parsing device 14 is prepared. The first character string data 12x is provided, for example, in Microsoft Word docx format, pdf, html, or the like. Alternatively, the information can be obtained by applying optical character recognition (OCR) to those for which such information is not previously obtained (eg, paper documents). The character string data input device 12 is assumed to be a storage device such as an HDD or SSD, or a server, but any device that provides character string data may be used.

Next, a syntactic analysis device 14 is prepared for parsing the character string data 12x and providing second character string data 14x divided into units of noun phrases and others. It should be noted that a noun phrase refers to a unit that can be replaced by a demonstrative pronoun. Examples of application in Japanese and English are given below.

For Japanese documents, a morphological analyzer such as Mecab can be used as the parser 14 . As a simple method for extracting noun phrases from Mecab's output results, for example, an operation of extracting parts between particles and punctuation marks and excluding those containing verb-like elements can be mentioned. However, it is not limited to this method. For example, in the case of an additional element, a patent publication, for example, instead of having two noun phrases, "first" and "○○", for "first XX", It can be devised such as setting an exception rule to treat it as a single noun phrase. The latter case also conforms to the rule that noun phrases are replaced by demonstrative pronouns. It is easy for those who have ordinary knowledge in the technical field of the present invention to extract noun phrases in various forms from the results of morphological analysis by Mecab.

In the case of an English document, for example, Stanford Parser can be used as the parser 14 to extract noun phrases. As in the case of Japanese, there are multiple possible extraction methods for noun phrases. For example, there are differences such as when segmenting with a preposition and when not.

Finally, the second character string data 14x is input to the display device 16, and the divided character string data are sequentially displayed to the reader in order from the front. Examples of the display device include the configuration of a graphic board and a display of a personal computer, a tablet, or a smartphone.

The above is the embodiment of the present invention. Next, the result of applying the present invention to a certain Japanese sentence will be shown as a specific example.

(First embodiment)
FIG. 1 is an example of applying the present invention to a sentence 12x saying "This invention is new and innovative." The procedure for obtaining these will be specifically described below.

The text 12x is input to the input device 12 such as a PC or smart phone.

The sentence 12x is then parsed. As a result of syntactic analysis, the sentence 12x is converted into character string data 14x of noun phrases and others. It is assumed that the character string data 14x maintains the order in the original sentence 12x. In other words, it is assumed that the text 12x can be roughly restored by combining the character string data 14x. Generally, I assume the possibility that some full-width characters will be converted to half-width characters.

Next, the character string data 14x are sequentially displayed to the reader. As the display device 16, the PC or smart phone can be used.

In the case of the sequential display, it is preferable that the display speed can be changed so that the display can be made in accordance with the reader's ability to read quickly. Furthermore, the format of the character string data 14x may be appropriately changed. For example, the font size of noun phrases may be made larger than that of others, or the characters may be colored.

FIG. 3 shows the prior art of the present invention. Displayed at a certain speed from top to bottom. Here, the text 12x is input to the morphological analyzer Mecab and the words written in spaces are sequentially displayed. This is an unnatural unit, and the number of parts after division increases, so there are disadvantages that the brain gets tired when reading the sequential display, and the reading time increases as the number of displays increases.

FIG. 1 shows an embodiment of the present invention. This display is divided into units called noun phrases, so the brain doesn't get tired. Furthermore, since the number of parts after division is reduced, the reading time is shortened.
