Description

Bibliographic search system through index queries.

Object of the invention

The present invention allows to take advantage of the text of the index or summary present in the books as a set of topics discussed in each of these books; This allows identify these issues in detail, than otherwise would go unnoticed by the mere use of the Title or Category theme of each of these books. The Search System Bibliographic through Index Consultations allows you to perform automatic mode searches by keywords or text searches full.

Although the solution used today, consisting of the coding of the book based on a hierarchy of previously selected themes ("thesaurus"), be extended to infinity (which in practice results impossible, as there are usually no more than three codes per book), the Bibliographic Search System through Consultations Index provides more information when storing and displaying the digitized photograph of each page of the book, thanks to which you can see the number of pages that the book dedicates to each theme, which means being able to appreciate the extension or depth with the one that each one of the books treats a certain subject. Also in digitized index reproduction by scanning You can see all the topics covered by the book (thus avoiding possible errors and transcription costs).

Thanks to the present invention, they are combined efficiently the different formats in which the scanned information: the graphic format (in which it is stored all the scanned photograph of the scanned page, using said format to show the result of a search performed by the user) and the text format (obtained from the previous format after being processed by an Optical Recognition program of Characters ("OCR"), using this format to perform keyword searches or text searches full).

The Bibliographic Search System through Index queries of the present invention allow grouping in its  Database the content of the books by any of the Possible search fields and access to information: both the index text, such as the contents of the Tabs Currently existing bibliographies (Author, Editor, Title or Title words, Publication Date, etc.). Thanks to this, an efficient search system is implemented through one or more search fields of those discussed above that allow to narrow the result of this search. Besides, the Inclusion in the Database of the information contained Usually in the Bibliographic Sheets, it allows the system be compatible with classic search systems bibliographies currently in existence.

The Database where the information is stored  bibliographic is updated continuously by the System of Bibliographic Searches; said Database being accessible to through the Internet, being able to make inquiries and / or updates on it, depending on the profile and rights assigned to each user. The present invention also allows, reproduce on paper or in computer format the content of the indexes of the books or the pages of the indexes of said books, thus facilitating the advertising promotions of the same.

In the chapter on costs and thanks to this invention, the work of library staff becomes unnecessary which until now was essential to catalog or code a book: both your study to perform coding by topics, as the keyboard entry of these codes (subject to possible transcription errors that will subsequently impact when performing searches).

The present invention is also advantageous. as for the costs of scanning book pages, for  carrying out said scan does not require guillotining beforehand said books; which means considerable cost savings: guillotined book cost (and therefore unused) and cost of operator responsible for guillotining. The System of Bibliographic Searches through Index Queries exceeds classic book scanning systems (where the opening the book and putting pressure on it to try to adapt it as much as possible to the flat surface of the scanner, which could cause the book to deteriorate and / or, which it is worse: that the scanned copy in digital format will occur shadows in the zone of union of the pages, causing that the words are distorted and not recognizable at the time of try to use them to perform searches). To solve the mentioned problem of distortion at the edges of the back of the book, the Bibliographic Search System object of the present invention, includes hardware and software elements (additional to the own ones of the scanner) that allow to correct the effects of the distortion, in addition to automating the flow of data from the scanner to Optical Character Recognition ("OCR") program, thus minimizing operator intervention.

Background of the invention

The sector in which the invention is applied is the of bibliographic searches for the location of books and / or Obtaining bibliographic lists containing certain search fields

For the classification of books, Typically Bibliographic records containing a series of fields among which are: Author, Title, Date Edition, Code corresponding to the topic or topics covered in the book, etc.

These Bibliographic Sheets must be made after a study of the content of the book and require a job to be performed by specialized personnel: librarians, usually.

In Spain, in addition to the specialist staff of each library, the Spanish ISBN Agency ("International Standard Book Number "), performs the task of signing and providing corresponding codes to all Spanish publishing production. In this case the Universal Decimal Classification is used ("CDU").

This system, although it allows to apply to each book several codes of matter, does not allow to reflect the rich theme that is collected in the content of the books and that in very good measure is reflected in the Index or Summary of said books.

The agencies that would benefit most from The use of this invention are mainly: Libraries, Bookstores, Publishers and Research Centers.
