Problems solved by technology

[0008] The disadvantage of this known method is that the indexing of the documents to be indexed is relatively labor-intensive and the retrieval of the documents may take a relatively long time, since the number of relations between different core concepts rapidly increases with the number of core concepts become very large

Embodiment Construction

[0019] FIG. 1 shows by way of example an overview of the different operating steps carried out in order to index a document 1 which can be retrieved and used according to an index 2 .

[0020] According to the invention, each document 1 to be indexed is analyzed for the presence of a core concept, stored in one or several thesauruses 3, and each document 1 is also analyzed for the different Possible relationships that exist between core concepts, which are stored in so-called relationship registers 4 .

[0021] This analysis can be done manually by a person, or automatically by a specific computer program.

[0022] In this way a collection of indexed documents 1 is created which together form an information source or knowledge cloud 6 .

[0023] Thus, document 1 may be a text document or a collection of drawings or audiovisual documents in the form of sound clips, video collages and the like.

[0024] Therefore, the thesaurus 3 is preferably structured in a hierarchical mann...

Abstract

A method for indexing and retrieving documents, characterized in that, for indexing a document (1), it includes a combination of the following steps: identifying the elements in the document (1) by means of one or several domain-specific thesauruses Core concepts; identifying relationships between core concepts (1) through one or several relationship registers (4); and indexing the document (1) according to the identified core concepts and relationships.

Description

technical field [0001] The present invention relates to a method for indexing and retrieving documents, and more particularly, to a method for digitally indexing and retrieving documents, where documents are all documents contained in text documents, sound clips, image collages, etc. The data. Background technique [0002] It is known to index the contents of text-based documents by means of one or several so-called thesauruses. [0003] The textual analysis of the text documents to be indexed is thus carried out by means of a software program which searches for so-called core concepts from one or more thesauruses in the text documents. [0004] The text document receives a specific index including the different core concepts based on the frequency and location of the discovered core concepts in the text document. [0005] In order to retrieve the indexed documents, the user can use known electronic search functions, whereby he / she introduces the core concept, and then, al...
