Abstract

A method and apparatus for retrieval of data relating to a plurality of levels of information comprises a store and a retrieval engine. These are arranged so that a plurality of storage areas are divided into a plurality of segments. Data relating to a given level of information for a topic is stored in a segment of one of the storage areas and data relating to at least one other level of information on the topic is stored in a corresponding segment of at least one other one of the storage areas. The retrieval engine comprising determines a selected level of information on a topic to be retrieved in response to a user request and is arranged to retrieve other levels of information on request or automatically.

Claims

1. A system for storage and retrieval of data including data relating to a plurality of levels of information comprising a store and a retrieval engine:

the store comprising;

a plurality of storage areas each being divided into a plurality of segments and being configured such that data relating to a given level of information for a topic is stored in a segment of one of the storage areas and data relating to at least one other level of information on the topic is stored in a corresponding segment of at least one other one of the storage areas;

the retrieval engine comprising;

means for determining a selected level of information on a topic to be retrieved in response to a user request;

means for retrieving data from a segment of the one of the plurality of storage areas comprising the selected level of information on a topic for display to a user; and

means for retrieving data relating to the at least one other level of information on the same topic from corresponding segment of the at least one other storage area in response to a request to change information level.

2. A system according to claim 1, wherein the segments each have an address such that segments in different storage areas relating to the same topic have a corresponding address within their respective storage areas.

3. A system according to claim 1 or 2, wherein the segments each have an address such that segments in different storage areas relating to the same topic have a corresponding address within their respective storage areas.

4. A system according to claim 1, 2 or 3, wherein each storage area comprises a uniquely identifiable database.

5. A system according to any of claims 1 to 4, wherein the storage areas each comprise a numbered database and segments within each database have an address, wherein any given segment is uniquely identifiable by an address and database number.

6. A system according to claim 5, wherein each segment of a numbered database has a corresponding segment in each of the other numbered databases with a corresponding address, each segment being uniquely identifiable by the address and database number.

7. A system according to any preceding claim, wherein each segment is referenced by one or more keywords.

8. A system according to claim 7, wherein the keywords for a segment of one storage area are the same as keywords for a segment relating to the same topic of another storage area.

18. A system according to any of claims 1 to 8, wherein the means for determining is a determiner and the means for retrieving comprises a retriever.

9. A method of retrieving data in a data structure in which data relating to a plurality of levels of information are stored in a plurality of storage areas, each storage area being divided into a plurality of segments, the plurality of storage areas being configured to store data relating to a level of information on a given topic, and data relating to other levels of the information on the topic in corresponding segments of other storage areas, comprising:

determining a selected level of information on a topic to be retrieve in response of a user request;

retrieving data from a segment of one of the plurality of storage areas comprising the selected level of information on the topic for display to the user; and

retrieving data relating to another level of information on the same topic from a corresponding segment of another storage area in response to a request to change information level.

10. A method according to claim 9, further comprising storing a default level of information to be retrieved for a given user, and changing the default level in response to a user request.

11. A method according to claim 9 or 10, wherein information stored in corresponding segments relate to identical keywords.

12. A method according to claim 9, 10 or 11, wherein information stored in any given level can be searched and retrieved independently from the other levels, and without retrieving any of the information stored in any of the other levels.

13. A method according to any of claims 9 to 12, further comprising:

analysing a request for information to determine whether information exists at an appropriate level within the data structure; and

in the event that information is not available, providing a response to a user that information is available at other levels or not available at all.

14. A method according to claim 13, further comprising:

identifying a segment or a group of segments in a storage area relating to the requested level of information;

identifying that the information is not available at the requested level;

analysing corresponding segments in other storage areas to determine whether information is available at other levels; and

providing a response to a user indicating levels at which information is available if available and that the information is not available if not available.

15. A computer program including computer program code which, when executed on a computer, executes the method steps of any of claims 9 to 14.

16. A computer readable storage medium having stored thereon a computer program according to claim 15.

17. A method of delivering data comprising the method of retrieving data according to any of claims 9 to 14 and delivering the data so retrieved over a computer network.

19. A system for storage and retrieval of data including data relating to a plurality of levels of information comprising a store and a retrieval engine:

the store comprising;

a plurality of storage areas each being divided into a plurality of segments and being configured such that data relating to a given level of information for a topic is stored in a segment of one of the storage areas and data relating to at least one other level of information on the topic is stored in a corresponding segment of at least one other one of the storage areas;

the retrieval engine comprising;

a determiner for determining a selected level of information on a topic to be retrieved in response to a user request;

a first retriever for retrieving data from a segment of the one of the plurality of storage areas comprising the selected level of information on a topic for display to a user; and

a second retriever for retrieving data relating to the at least one other level of information on the same topic from corresponding segment of the at least one other storage area in response to a request to change information level.
