Abstract

A document search system comprises an ontology editor including a graphical user interface for creating and modifying a hierarchical query data structure (ontology) containing a plurality of search terms (concepts), a scanner scanning a communication network and providing a scan list, an ontology indexer matching the documents stored in the scan list with the search terms contained in the query data structure (ontology) and indexing the documents dependent on the occurrence of one or more of the search terms in the document, and a display unit for displaying the indexed documents in a hierarchical order. It further comprises a graphical user interface for selecting search terms from the query data structure (ontology); thus formulating a query, and another one for displaying graphical representations of results of the search and for controlling the graphical representations. And it further comprises a user interface for selecting one or more document sets (e.g. websites) or documents which are not scanned and indexed at the time, to scan and index them on the fly and make them searchable immediately after the scan and index job is finished.

26. The method of any one of claims 1 to 25, wherein a search based on a specific query data structure is carried out repeatedly after predetermined time periods, the new results are compared to the old ones and the differences are shown in the graphical representation.

27. A method of any one of claims 1 to 26, further comprising the step of simulating a form wrapper for accessing a data base.

28. The method of claim 27, wherein the simulated form wrapper is an html form.

40. A computer program comprising program code for carrying out the methods of any one of claims 1 to 29.

7. A hierarchical query data structure (ontology) administration method in a communication network, wherein the multiple use of a search term in the query data structure is checked.

8. The method of claim 7, wherein different query data structures (ontologies) are assigned to different administrators.

9. The method of one of claims 7 to 8, wherein the building steps of a query data structure are automatically tracked.

10. The method of one of claims 7 to 9, comprising a thesaurus function for providing synonymous terms to search terms contained in the query data structure.

11. The method of one of claims 7 to 10, comprising language recognition and translation steps for translating search terms into a different language.

12. The method of one of claims 7 to 11, further comprising a definition search step for searching, upon request, a definition of a selected search term over the communication network.

16. A document search method in a communication network, comprising the steps of:

a) providing a query data structure (ontology) containing a plurality of search terms,

b) carrying out a document search based on search terms selected from the query data structure,

c) generating a graphical representation of the search result dependent on the match properties of the searched documents and a set of additional result parameters,

d) providing a user interface for controlling the graphical representation of the search result dependent on the match properties and/or the result properties, and e) displaying the graphical representation of the search result on a display medium.

17. The method of claim 16, wherein the match properties include the number of matching search terms (concepts), the frequency of matching search terms, content related properties like a document title, document URL or links to other documents.

18. The method of claim 16 or 17, wherein the result parameters include the document size, language, publication date, domain extension and server address of a document.

19. The method of one of claims 16 to 18, wherein the user selectable control of the graphical representation of the search result includes imposing different weights to different search terms.

20. The method of claim 19, wherein the display of the search result parameters include server result parameters like the server size, number of matching documents on a server or the domain extension of the server.

21. The method of any one of claims 16 to 20, wherein the selection of a graphical representation of a displayed document set of the search result initiates a more detailed display of a document set or a link to an individual document.

23. The method of one of claims 16 to 21, wherein a number of model result display profiles for standard search result analyzing tasks are provided.

24. The method of claim 23, wherein the default result display or the model result display profiles can be modified by the user.

25. The method of claim 23 or 24, wherein a model search result display profile is adapted to the user'"'"'s behavior by an automatic learning algorithm.
