Abstract

A method for indexing and retrieving documents, characterized in that, in order to index a document, it comprises a combination of the following operational steps: identifying core concepts in the document by means of one or several domain-specific thesauri; identifying relationships between core concepts in the document by means of one or several relationship registers; and indexing the document on the basis of the identified core concepts and relationships.

Claims

1. A method for indexing and retrieving documents, whereby, in order to index a document, it comprises a combination of the following operational steps:

identifying core concepts in the document by means of one or several domain-specific thesauri;

identifying relationships between core concepts in the document by means of one or several relationship registers; and

indexing the document on the basis of the identified core concepts and relationships.

2. The method according to claim 1, wherein the above-mentioned thesauri are hierarchically structured.

3. The method according to claim 1, wherein the above-mentioned relationship registers comprise linguistic relationships.

4. The method according to claim 1, wherein the above-mentioned relationship registers are hierarchically structured.

5. The method according to claim 1, wherein the above-mentioned thesauri and relationship registers are integrated so as to form what is called an onto-thesaurus.

6. The method according to claim 1, whereby, for retrieving indexed documents, it comprises the following operational steps:

the introduction by the user of one or several search terms from one or several of the above-mentioned thesauri;

the selection of documents whose index comprises one or several of these search terms;

the introduction by the user of one or several relationships from the relationship registers;

the selection of documents whose index comprises the above-mentioned relationship from the above-mentioned, already selected documents; and

showing the last selected documents as a result.

7. The method according to claim 1, whereby, for retrieving indexed documents, it comprises the following operational steps:

the introduction by the user of one or several relationships from one or several of the above-mentioned relationship registers;

the selection of documents whose index comprises one or several of these relationships;

the introduction by the user of one or several search terms from the thesauri;

the selection of documents whose index comprises the above-mentioned search terms from the above-mentioned, already selected documents; and

showing the last selected documents as a result.

8. The method according to claim 5, whereby, in order to retrieve indexed documents, it consists of introducing one or several search terms in the above-mentioned onto-thesaurus;

selecting the documents whose index contains the above-mentioned search term, search terms respectively; and

showing these selected documents.

9. The method according to claim 1, whereby the found documents are shown in two phases, whereby, in a first phase, a survey is given of the different found documents, ordered according to their relevance, and whereby, in a second phase, after a selection, individual documents can be represented.

10. The method according to claim 9, whereby in the above-mentioned first phase and/or second phase of showing the documents found, a color code is used which indicates what core concepts occur in the different documents and which makes it possible to visualize a degree of implicitness of the core concepts in the index of the documents.

11. The method according to claim 1, whereby, for indexing and retrieving the documents, use is made of a computer program.

12. A computer program for indexing and retrieving documents, whereby said computer program allows to apply the above-mentioned method according to claim 1.

13. A data carrier, whereby said data carrier is provided with a computer program according to claim 12.
