[0020]

FIG. 1 shows a schematic configuration of a dictionary search system according to an embodiment of the present invention. This system is an operating system such as Windows (hereinafter referred to as “O
S), and operates in conjunction with applications such as word processing software, e-mail software, and Web browser, and includes a character string extraction processing unit 1, a designated position recognition unit 2, a language recognition processing unit 3, a morpheme Analysis processing unit 4, dictionary search processing unit 5, meaning display processing unit 6, mark display processing unit 7
In addition to the above processing units, an electronic dictionary storage unit 9 storing a plurality of types of dictionary files 8 to be searched is provided as a configuration.

The above-mentioned dictionary search system is, specifically,
A program file for realizing the functions of the processing units 1 to 7 of FIG. 1 and each dictionary file 8 for constructing the electronic dictionary storage unit 9 are installed in the hard disk device 13 of the personal computer 17 as shown in FIG. It is constituted by.

Each program file is stored in a CD-ROM provided as package software for search processing.
It is stored in the hard disk drive 13 by setting it in the ROM drive 14 and performing a predetermined installation operation.

The dictionary file 8 is a computerized "semantic dictionary" for performing a search using words in a predetermined language as a key, such as a Japanese language dictionary, a Chinese-Japanese dictionary, and a Korean-Japanese dictionary. Is provided in a form recorded on one or more CD-ROMs for each dictionary. However, the present invention is not limited to this, and a plurality of types of dictionary files 8 may be provided as one package software, or a predetermined dictionary file 8 may be incorporated in the search processing package software. The dictionary file 8 fetched from an external database such as the Internet is stored in the hard disk drive 13.
It is also possible to install it inside.

However, it is not always necessary to set data of a plurality of types of dictionaries in the electronic dictionary storage unit 9. To implement the present invention, at least one dictionary (however, a plurality of dictionaries are not line-filled without filling one word). The dictionary file 8 may be stored as long as the dictionary file 8 is limited to a dictionary of a language that takes a form of displaying over lines. Instead of installing the dictionary file 8 on the hard disk device 13, a CD-ROM storing the dictionary file 8 to be searched is stored in a CD-ROM.
The search may be performed by setting in the ROM drive 14.

The hard disk device 13 is also installed with program files and data files for operating the OS and various applications. The CPU 10 serving as a control subject is appropriately provided with a ROM 11
By executing various programs in the hard disk 13 while accessing the RAM 12 and the RAM 12, the dictionary search system is started up in a state where higher-level applications such as the word processing software, the e-mail software, and the Web browser are operating, and a predetermined Is executed.

The input unit 15 in FIG. 2 is constituted by a keyboard for inputting characters and a pointing device such as a mouse. The monitor 16 is composed of a display device such as a CRT or an LCD. On the display screen at the time of the search processing, a display window of a host application and a meaning display window for displaying a search result of an electronic dictionary are provided. Be established.

The dictionary search system of this embodiment is activated in response to a user's search operation while a document in a predetermined language is displayed in a display window of a higher-level application. This search operation is performed by operating a search icon in the window with a mouse or the like and then specifying a keyword to be searched on the document.
In this embodiment, in order to simplify the operation, the setting is made such that the keyword is automatically extracted just by clicking the display position of any character constituting the keyword. However, the present invention is not limited to this. Alternatively, a method of specifying a range of two or more characters constituting a keyword or all characters may be adopted.

The character string extraction processing unit 1 incorporates an API function for redrawing a character string in a display window. Normally, this function is executed on the OS side. However, in this embodiment, the API function of the character string extraction processing unit 1 is first executed in response to the search operation, and the Data for redrawing all character strings (hereinafter, simply referred to as “redraw data”) is fetched, and after that, the process is passed to an API function on the OS side to execute the actual redraw process.

More specifically, the redrawing data includes, for each line in the display window, a character code of each character constituting the line, coordinate position data of a character at the head of the line, a font code, and the like. . The character code is code information assigned to each character in order to display characters corresponding to a language, such as S-JIS code for Japanese and GB code for Chinese. In addition to the reference code information set in, the code information uniquely set by a maker of a character input support system (IME) is also an object. The font code is a code indicating the name of the typeface of the character to be displayed, and it is possible to specify a language suitable for the document from the code. The redrawing data is provided to the language recognition processing unit 3 and the morphological analysis processing unit 4 to perform a process of specifying a word to be a keyword, and to a mark display processing unit 7 for displaying a mark of a keyword described later. Used for

When the above-described search operation is performed, the upper application sends a "message" notifying the click position in the display window to the OS. The designated position recognizing unit 2 recognizes the click position by executing a “hook” process referring to the message. The recognized coordinate position is given to the morphological analysis processing unit 4.

The language recognition processing section 3 uses the font code in the re-drawing data obtained from the character string extraction processing section 1 to determine in which language the original is created. This determination result is given to the morphological analysis processing unit 4 and the dictionary search processing unit 5.

The morphological analysis processing unit 4 receives the result of the determination, performs morphological analysis on the character string based on the redrawn data according to the determined language, and decomposes the character string for each word. . Further, the morphological analysis processing unit 4 refers to the morphological analysis result corresponding to the click position provided by the designated position extraction unit, and specifies a word existing at the click position as a keyword. Note that when performing the search operation, the user has designated any character that constitutes the word to be a keyword, so that the character at this click position is the first character, the last character,
Any of the words located in the middle of the character string will be extracted as a keyword.

As described above, since the redrawing data extracted by the character string extraction processing unit 1 represents the data of all the character strings in the display window, in the morphological analysis processing, two lines are displayed. The words that are being
It will be extracted without any problems. Also, if the number of characters in one line is extremely small, such as in a headline, one word may be displayed over three or more lines.In such a case, the word may be divided. It is extracted without.

Therefore, even when a character string of a word specified as a keyword extends over a plurality of lines, the possibility of erroneous extraction of the keyword is extremely low, and a highly accurate search process can be performed.

The dictionary search processing section 5 selects a dictionary file 8 to be searched according to the result of the judgment by the language recognition processing section 3 and then extracts the dictionary file 8 by the morphological analysis processing section 4. Execute a search process using a keyword. This search result is passed to the meaning display processing unit 6, and the meaning display processing unit 6 opens a meaning display window at a predetermined position on the monitor screen and displays the search result in the window.

The mark display processing unit 7, which is another display processing unit, receives the re-drawing data from the character string extraction processing unit 1.
Each of the keywords is given by the dictionary search processing unit 5. After extracting all positions where the keyword is displayed in the entire character string represented by the redrawing data, the mark display processing unit 7 extracts the keyword at each display position of the keyword in the actual display window. The character string to be displayed is switched to a state where marking such as black-and-white inversion display and color display is performed and displayed (hereinafter, this display is referred to as “mark display”).

For the purpose of simply specifying a keyword, it is not always necessary to extract all the character strings in the display window, but only to extract the display line of the designated character and the character strings of each line before and after it. May be. However,
In order to extract keywords with high accuracy from a document created under any conditions, it is desirable to extract all character strings. In addition, in order to display marks at all positions where the extracted keywords are displayed in the display window, it is necessary to extract all character strings.

FIG. 3 shows a procedure of a series of search processing by the electronic dictionary search system. In the following description, the search operation is described as being performed by a mouse click operation. However, the search operation can be realized by an operation such as pressing a carriage return key with a cursor positioned at a predetermined position using a keyboard. The control procedure of FIG. 3 is started in response to a click operation of a search icon by a mouse. In the first ST1, a process of recognizing a click position in a display window of a higher-level application in response to a click operation, A process of reading a character string constituting the document is executed.

FIG. 4 shows an example in which a click operation is performed on the display window 20 on which a manuscript in Chinese is displayed. In this manner, by clicking the mouse cursor 22 on a predetermined constituent character in a word serving as a keyword and performing a click operation, a search process of an electronic dictionary using this word as a keyword is instructed.

FIG. 5 shows a detailed procedure of ST1. When the click operation as shown in FIG. 4 is performed on the display window 20 of the running application, the application sends a message notifying the type and the coordinate position of the clicked application to the OS. . Designated position recognition unit 2 of dictionary search system
Hooks this message to recognize the type of application displaying the clicked document and the position where the display window of the application is opened (ST1-1, 1-2). Further, the designated position recognizing unit 2 extracts the coordinates of the click position from the message and recognizes the coordinates as the display position of the keyword (ST).
1-3).

Next, the character string extraction processing section 1 executes the API function set therein, thereby re-drawing the data of all the character strings (hereinafter referred to as “document character strings”) of the document in the display window. Acquire (ST1-
4). Then, in the next ST1-5, ST1-3, 1-4
The click position and the redrawing data obtained in step (1) are transferred to the other processing units shown in FIG. 1, respectively, and the routine of ST1 ends.

Returning to FIG. 3, in the next ST2, the language recognition processing unit 3 reads the font code of the redrawing data and recognizes a language that matches the original character string. After receiving the recognition result, the morphological analysis processing unit 4 performs a morphological analysis on the document character string, specifies a word present at the click position, and uses the word as a keyword as a dictionary search processing unit 5 and a mark display processing unit. 7 is output.

Upon receiving the keyword, the dictionary search processing unit 5 searches the dictionary file 8 corresponding to the language recognized by the language recognition processing unit 3 (ST).
4). When the corresponding data is searched, a meaning display window is opened at a position where the display window 20 of the application is not hidden, and the search result is displayed in the window (ST4, ST5).

On the other hand, the mark display processing section 7 extracts all display positions of the keywords in the display window 20 using the redrawn data obtained from the character string extraction processing section 1, and marks the keywords at each display position with a mark. indicate. Note that both the display of search results and the display of keyword marks are displayed on the OS.
This is realized by notifying information to be displayed and performing display control.

FIG. 6 is a display screen of the monitor after the search processing for the search operation of FIG. 4 has been performed. In the display window 20 of the application, a word extracted as a keyword at the click position is displayed. In addition, the same word displayed in the window 20 is highlighted in black and white. A meaning display window 21 is opened at a position overlapping a part of the display window 20, and a search result is displayed in the window 21. The mark display is not limited to the black-and-white inverted display and the change of the display color. Each character constituting the keyword may be underlined, or a predetermined mark may be added to the head or rear of the keyword.

The user recognizes the meaning of the word used as the keyword from the display contents of the search result, and proceeds with creating or browsing the manuscript. At this time, in the display window 20 in which the manuscript is displayed, marks are displayed at all display positions of the searched words, so that the meaning of these words is determined by the display contents in the meaning display window 21. By confirming again, the inefficient work of repeating the same search can be avoided.

In this manner, a series of search processing is completed. When the next search operation is further performed under the state of FIG. 6, ST7 becomes "YES" and the process shifts to ST1.
The same procedure as described above is executed for a new operation. On the other hand, if the user confirms the display contents of the meaning display window 21 and performs an operation of closing the window 21, ST8 becomes "YES", and the operation of the dictionary search system ends.
