Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a book management system for managing electronic books.

[0002]

2. Description of the Related Art In a conventional example of a book management system for managing digitalized books, an index representing the book is set at the time of book registration, and each book is preset in order to improve the convenience of the book search. Set keywords for each. When searching for registered books, the index and keyword of the previous term are input, and books that match all of these are reserved and used as search results.

[0003]

In such a conventional technique, it is difficult to set a uniform keyword because the keywords set at the time of registering / retrieving a book have variations in the keyword selection criteria depending on the judgment of the setter. is there. Further, if a large number of keywords are set for the convenience of search, not only the registration work will be complicated but also the operation itself of the book management system may become difficult. Furthermore, depending on the keyword, a word that originally has the same or almost the same meaning but has a different formally (hereinafter, “synonym”)
,), Or symbols, abbreviations, codes, etc., and if the keyword setting is kept to the minimum limit, the convenience of searching will be impaired. In addition, since only the management data such as the keyword is searched, if the management data is insufficient, the inconvenience that the necessary books cannot be searched occurs.

The present invention has been made in order to eliminate such inconvenience, and it is easy to select keywords, it is possible to maintain the uniformity of the selection criteria, and further, book management that enables efficient retrieval. The purpose is to provide a system.

[0005]

In order to achieve the above object, the book management system of the present invention comprises an input / output device, a substantive book data file storing data relating to each book to be managed, and the substantive book data. A management data file that stores the index that manages the file, a keyword library that stores the keywords used to search the data in the books in this management data file, and a synonym for each keyword stored in this keyword library. The synonym library in which the keywords registered in the library are grouped into a plurality of synonym groups as a representative keyword and stored, and the keywords input through the input / output device for searching the books are present in the keywords of the keyword library. To check whether If there is no input keyword as a result of the collation by the first collating means and the first collating means that outputs the keyword inputted as a search keyword, the keyword inputted is in the synonym library. Is output from the first or second matching means, and second matching means that replaces the representative keyword of the corresponding synonym group and outputs it as a search keyword. A search means is provided for executing a keyword search using the management data file according to the search keyword and displaying the execution result on the input / output device.

In the book management system thus constructed, it is easy to select a keyword by using the keyword library, and it is possible to ensure uniformity because the keyword is selected based on the already selected keyword. Further, since all the words having the same meaning can be searched by setting a small number of keywords using the synonym library, it is possible to efficiently execute a necessary book.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows one embodiment of the present invention. The book management system shown in FIG.
It is composed of an input / output device 1 for performing a search, a data processing device 2 including a CPU, a book management data file 3, and an actual book data file 4. Of these, the book management data file 3 is a management data file 31 that stores information for managing each physical book, a keyword library 32 that stores keywords used for retrieval,
A synonym library 33 that stores synonym data of each word registered in the keyword library 32, and a fixed book keyword that stores a keyword group defined for each fixed book group classified by the index used in the management data file 31. It consists of a library 34. The management data file 31 includes a book ID 311 for each book, a document title and an organization template group,
Various indexes 312 such as storage location of actual book data,
One or a plurality of keywords 313 registered for each book for use in the search are stored. The synonym library 33 groups synonyms for each keyword stored in the keyword library 32, and stores synonym groups 332 in which the keywords registered in the keyword library 32 are set as representative keywords 331. The book name 341 and one or more keywords 342 defined for each standard book are stored. The book management system of the present invention uses the book management data to store the text book data 41 stored in the actual book data file 4,
The raster book data 42 and the vector book data 43 are managed. Here, the text book data means book data composed of a text file, the raster book data means book data to be subjected to raster graphic processing, and the vector book data is used in CAD (Computer Aided Design) or the like. , Means book data represented as a straight line connecting two points.

Operation of the system of FIG. 1 will be described with reference to FIGS.
This will be described with reference to FIG. 2 and 3 are flowcharts showing the procedure of keyword registration and keyword search executed by the data processing device 2, respectively.

First, the procedure of keyword registration will be described with reference to FIG. When registering a keyword, the book management system first determines whether or not the book is a text file (block 51), and if it is a text file, searches the character string in the book to search the keyword library 32 and synonyms. All the words registered in the library 33 are picked up (block 52). After all the words extracted here are replaced with the representative keyword 330 corresponding to this word in the synonym library 33 (block 53), it is displayed as a keyword candidate on the input / output device 1 (block 54). Also, block 5
For a book that is not a text file in 1, all the keywords registered in the keyword library 32 are displayed on the input / output device 1 as keyword candidates. In any case, after the actual keyword is selected by the registrant from these keyword candidates (block 55), registration in the management data file 31 is performed.

Next, the procedure of keyword search will be described with reference to FIG. First, a searcher inputs a keyword for a search using the input / output device 1 (block 61).
And entered keywords and keyword library 3
2 is matched (block 62) and if the keyword is present in the keyword library 32, this word is used for the search. If it does not exist in the keyword library 32, it is compared with the synonym library 33 (block 63). If it exists in the synonym library 33, the representative keyword of the synonym group is replaced with the keyword input as the search keyword. (Block 64). If the keyword does not exist in the synonym library 33, it means that there is no corresponding keyword (block 6
5) The search ends. Search keyword is block 62
Alternatively, if it is extracted in any of the blocks 63, (1) keyword search (block 661) using it,
(2) After extracting the corresponding book (block 67) by one of the methods of the fixed form book search (block 662) and (3) text search (block 663), the result is output to the input / output device 1 (block 68). ), The search ends.

Next, three search methods (1) to (3) will be described with reference to FIG. First, in the keyword search in block 661, the search keyword extracted in block 62 or 64 is collated with the management data file 31, and the extracted actual data name is input / output device 1
Is displayed (block 68) and the search ends. Next, in the fixed form book search of block 662, the search keyword extracted in block 62 or block 64 is collated with the fixed form book keyword library 34, and when the corresponding fixed form book group is extracted, based on it. The management data file 31 is collated and the corresponding book is extracted (block 67), and the result is input / output device 1
(Block 68) and the search ends. Finally, the text search is performed based on the search keyword extracted in block 62 or 64 in the management data file 31.
The keyword used by directly matching the word used in the index such as the book title and the word used in the text data 41 in the actual book data file 4 is used. The book is extracted, the book data name is displayed on the input / output device 1 (block 68), and the search ends.

According to the embodiment described above, it is possible to unify the keywords to be used when registering the keywords, and it is possible to easily and quickly select the keywords to be registered without omission.

In the search, the synonym library 3
By using 3, it becomes possible to use a word that has a similar meaning but cannot be used as a keyword because it does not completely match the registered keyword as a keyword. . Further, by using the standard book keyword library 34, it becomes possible to carry out a collective search for related books.

Further, by the text search, it is possible to search even a book for which no keyword is set.

[0016]

As described above, according to the present invention, it is possible to easily select a keyword and maintain the uniformity of the selection criteria, and at the time of keyword search, a related expression method by a synonym search. It is possible to efficiently perform a wide range of keyword searches regardless of the above. In addition, it is possible to unify the keywords at the time of keyword registration and to register the necessary keywords without omission.
