Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called electronic book in which character information and image information are recorded on a CD-ROM and a search method for the electronic book.

[0002]

2. Description of the Related Art In a conventional electronic book reader, the number of input keys is smaller than that of a computer keyboard. Therefore, when inputting Japanese, "Hiragana" converted by Romaji conversion is used. Even when searching for a kanji or a word having a kanji at the beginning of the word, the search is executed by matching / mismatching the reading of the "hiragana".

FIG. 3 shows a display example of an electronic book player at the time of a conventional search. When "KAMI" is entered from the keyboard, the key code-kana conversion means provided inside the electronic book player is used. The kana character is converted into "kami", and this "kami" is displayed as a search word on the search screen illustrated in FIG.

The search condition is shown in the next line of this screen. As is well known, the search is a match search such as whole match, start match, partial match, end match, etc. Although there is an unmatched search for searching, in this figure, the case where the leading match search is selected as the search condition is illustrated.

As described above, if the search word is "Kami" and the search condition is the head match search, the electronic book player accesses the electronic book and the content of the article in which the Hiragana "Kami" is the head of the reading kana. Alternatively, the index heading in which the kana of "Hiragana" is read and which is the head of the kana is displayed. In the illustrated example, the following ten index headings are exemplified as the search results.

When the index heading is displayed as in the example shown in the figure, by selecting any one of the ten search results with the numeric keys or the cursor keys, the selected index can be displayed. The corresponding more detailed contents will be read from the electronic book and displayed on the screen.

[0007]

Even if the word "Kami" entered from the keyboard in the above example is to be searched for a word related to "God", as shown in the example of FIG. Besides words such as "God" and "God",
Search results include homonymous kanji such as “top”, “paper”, and “hair”, “paper bags” and “hairstyles” that begin with these kanji, and “nap” that happens to match the beginning of the reading. Is displayed.

These useless search answers increase the number of answers, and it becomes necessary to further select a desired word or phrase regarding "God" from the search answers. Especially, the number of answers is large and the answers are displayed on a plurality of screens. In such a case, there is a problem that the screens must be sent one after another to find a desired word or phrase.

An object of the present invention is to provide an electronic book and electronic book player search system in which homonyms are not returned as search results.

[0010]

[MEANS FOR SOLVING THE PROBLEMS] Input means for inputting kana characters by key code-kana conversion from input key code, character pattern ROM for converting character code into character pattern, and recorded in electronic book by character code An electronic book for use in an electronic book player having at least a search means for searching an index, wherein kana-kanji conversion for converting a character code of kana character into a character code of kanji appearing in the index The dictionary is recorded along with the index and text.

Further, in the above-mentioned electronic book player, the code corresponding to the kana character obtained by the key code-kana conversion in the input means is recorded in the electronic book, and the kana-kanji conversion dictionary is used for the kanji character code. After converting to, I tried to search by the character code of this Kanji.

[0012]

According to the present invention, a search is executed by using the Kanji converted from the Roman character input by the Roman character conversion as the search condition, and only the search result matching the search key is displayed and output. Kanji is not output in the search answer.

Therefore, in the above-mentioned example illustrated in FIG. 1, "same", "paper", "hair" and other synonymous kanji, and "first stage", "paper bag", and "hairstyle" having these kanji as the initial words Are not output because they do not match the search conditions, and only the words beginning with the required “God” are displayed as the search results, as illustrated in FIG. 2 (b) described later.

1 is a flow chart conceptually showing an embodiment of a search method in an electronic book player according to the present invention, and FIG. 2 is a display example of an electronic book player when the search method according to the present invention is applied. It is the figure which showed.

The left side of FIG. 1 is the processing in the electronic book player, and the right side is the items recorded by the electronic book, and the line connecting them and the characters written on them are used to connect between the electronic book and the electronic book player. The relationship is shown.

When a user inputs a key from the keyboard of the electronic book player, the key code corresponding to this key is converted into a character code corresponding to a kana character by the Roman character-kana conversion dictionary.

This character code is sent to the character pattern ROM in the electronic book player, and the character pattern of the kana character read from the character pattern ROM by this kana character code is displayed at the top of the display device illustrated in FIG. 2 (a). Display in the search word column of the line.

Further, the area of the kana-kanji conversion dictionary created with a structure such as "kana character code (column) + separator + kanji character code (column)" of the electronic book with this character code. To read the character code (column) of the kanji (kana) having the character code corresponding to this kana character at the head from the electronic book.

Then, the read character code (column) of the kanji (kana) is converted into a corresponding character pattern in the character pattern ROM, and this pattern is sequentially displayed in the following ten display areas in FIG. 2 (a). indicate.

Incidentally, is it recorded in this electronic book?
It is not necessary to prepare conversion data for all kanji in the kanji conversion dictionary, and it is preferable to target only the kanji that appear in the index of the electronic book in terms of extra kanji not being displayed and recording capacity. The contents of the dictionary will vary depending on the type of electronic book.

When hiragana is used as a search word, the character code of this hiragana is used for the electronic book
Since it is not necessary to convert to the kanji character code using the kanji conversion dictionary, the hiragana character code from the romaji-kana conversion dictionary is shown by the dotted line in FIG. 1 in order to select the search character described below. You may use it as it is.

In the display screen as shown in FIG. 2 (a), the user presses a numeric key corresponding to the number attached to the head of the display area in which the kanji (kana) desired to be searched is displayed or the cursor is pressed. When you select a display area by operating the keys and then instruct execution by pressing the "YES key", for example, the character code (column) of the kanji (kana) displayed in this selected display area will Do a search.

In other words, the electronic book records an index that stores the places where the text appears in correspondence with the character code (column) of the kanji (kana), and the electronic book player uses the search word and the search as described above. This index is searched according to the condition and the corresponding index is read from the electronic book, the text is read according to the information indicating the place of publication in this index, and the following 10 areas of the display screen shown in FIG. indicate.

As a method of reading and displaying the text, one search result (text) is displayed by using the entire display area described below instead of the above display method, and further, a predetermined appropriate operation key is used. The next search result may be displayed by operating.

Further, in the above-mentioned embodiment, the text is displayed directly from the result of searching the index, but as in the above-mentioned conventional example, the contents of the index are displayed as a search result and further selection is made. However, in this case, it is preferable to keep the character code (column) of the kanji (kana) of the index, that is, the headline, long enough to estimate the content of the text.

[0026]

According to the present invention, since a search is performed using Chinese characters, homonyms can be excluded from the search answer, and a particular effect can be achieved in which only the desired answer is obtained.
