Abstract

An application management system includes an application manager for managing an application and associated with a database resource storing a plurality of entities. The application manager includes an input for receiving an input defining an event in which a user is involved in the application or an input defining an event involving a manipulation of at least one entity in the database resource. A context is associated with the event and is represented by a set of references to the entities stored in the database resource. The application manager includes a situation representation manager for determining a situation representation that defines a subcontext. The situation representation manager identifies a subset of references to a plurality of entities that are relevant to the event. The application manager adapts the behavior of the application to a situation or a future situation on the basis of the situation representation.

Claims

1. An application management system comprising:

a database resource for storing a plurality of entities associated with an application; and

an application manager for managing the application, the application manager comprising;

an input channel for receiving an input defining an event in which a user is involved in the application or an input defining an event involving a manipulation of at least one entity in the database resource, wherein a context is associated with the event and is represented in the event by a set of references to a plurality of the entities stored in the database resource; and

a situation representation manager for determining a situation representation in terms of a subset of the set of references to the plurality of entities to define a subcontext, wherein the situation representation manager is arranged to identify the subset of the references to the plurality of entities which are relevant to the event, and wherein the application manager adapts a behavior of the application to a situation or a future situation on the basis of the situation representation.

2. The system according to claim 1, wherein the situation representation manager includes an activation value assignor for assigning an activation value to the plurality of entities defined by at least one of the set or subset of references, and a determining means for determining the subset of entities to be included in the situation representation on the basis of the activation value.

3. The system according to claim 2, wherein the determining means determines the situation representation on the basis of the activation value with respect to a predetermined threshold.

4. The system according to claim 3, wherein the application manager includes a storage medium for storing the situation representation, wherein the stored situation representation is used to determine the behavior of the application in a future situation.

5. The system according to claim 1, wherein the activation value for an entity is derived in accordance with a degree to which the entity is related to the situation.

6. The system according to claim 1, wherein an entity directly related to the situation is assigned an activation value having a higher relevance than an entity indirectly related to the event.

7. The system according to claim 1, wherein an entity having a plurality of relations to a directly related entity is assigned an activation value on the basis of the number of relations.

8. The system according to claim 1, wherein the determining means determines the subcontext as being relevant for the situation by a successive extension of an initial subset that initially includes references to entities directly affected by the event.

9. The system according to claim 8, wherein the determining means is arranged to add entities to the initial subset if they are related to at least two of the entities of the initial subset or on the basis of the activation value assigned to the entities to be added, wherein the activation value is assigned to the entities to be added in accordance with the relations of the entities to be added to the entities included in the context and the activation values assigned to the related entities.

10. The system according to claim 9, wherein the activation value assignor assigns a subcontext activation attribute to the entities included in the subcontext, which is dependent on the iteration in which an entity has been included in the subcontext.

11. The system according to claim 10, wherein the subcontext activation attribute for an entity included in the subcontext is calculated by taking into account the number of subset entities to which the entity included in the subcontext is directly related.

12. The system according to claim 1, wherein the activation value of an entity is calculated as a sum of two components, wherein a first component is the sum of the activation values of directly related context entities, and a second component is the sum of the activation values of directly related sub context entities.

13. The system according to claim 12, wherein the sum of two components is a weighted sum, and wherein the activation value of each related entity is multiplied by a weighting factor depending on the kind or type of relation.

14. The system according to claim 2, wherein the determining means determines the subset in a cyclical manner.

15. The system according to claim 4, wherein the storage medium is accessible by a context modeler for modeling a dynamic context representation on the basis of the stored situation representation.

16. A method of managing an application comprising:

storing a plurality of entities associated with an application in a database resource;

receiving an input defining an event in which a user is involved in the application or an input defining an event involving a manipulation of at least one entity in the database resource, wherein a context is associated with the event and is represented in the event by a set of references to a plurality of the entities stored in the database resource;

determining a situation representation in terms of a subset of the references to the plurality of entities to define a subcontext, wherein the subset of the references to the plurality of entities which are relevant to the event are identified; and

adapting the behavior of the application to a situation or a future situation on the basis of the situation representation.

17. The method according to claim 16, wherein determining a situation representation includes assigning an activation value to the plurality of entities defined by the set of references, and determining the subset of entities to be included in the situation representation on the basis of the activation value.

18. The method according to claim 17, wherein determining a situation representation further includes determining the situation representation on the basis of the activation value with respect to a predetermined threshold.

19. The method according claim 16, further comprising:

storing the situation representation, wherein the stored situation representation is used to determine the behavior of the application in a future situation.

20. The method according to claim 16, further comprising:

deriving the activation value for an entity in accordance with a degree to which the entity is related to the event.

21. The method according to claim 16, further comprising:

assigning an activation value to an entity directly related to an event having a higher relevance than an entity indirectly related to the event.

22. The method according to claim 16, further comprising:

assigning an activation value to an entity having a plurality of relations to a directly related entity on the basis of the number of relations.

23. The method according to claim 16, further comprising:

determining the subcontext as being relevant for the event by a successive extension of an initial subset that initially includes references to entities directly affected by the event.

24. The method according to claim 23, further comprising:

adding entities to the initial subset if they are related to at least two of the entities of the initial subset and on the basis of an activation value assigned to the entities to be added, wherein the activation value is assigned to the entities to be added in accordance with the relations of the entities to be added to the entities included in the context and the activation values assigned to the related entities.

25. The method according to claim 17, further comprising:

assigning a subcontext activation attribute to the entities included in the subcontext, which is dependent on the iteration in which an entity has been included in the subcontext.

26. The method according to claim 17, further comprising:

calculating a subcontext activation attribute for an entity included in the subcontext by taking into account the number of subset entities to which the entity included in the subcontext is directly related.
