Status of research area (1)
 Using technologies: UDDI, Preference SQL, Preference XPath
Problems:
 Requests contain no Semantic
 Non-personal matching-functions :
User priorities are not full integrated into Request and
therefore they cannot be taken into account
 No semantics-based matching :
Direct matching of Request with Service Descriptions

Status of research area (2)
 Skyline Queries
 Problems:
No appropriate algorithms to decide
which point of Skyline is a most
suitable for user preferences
 Service Globe
 Problems:
Formulation of valid user requests is not
supported

Description
Type Condition
Defines the type (class) of set members
Direct Condition
Defines a condition which concerns
directly to potential objects of set
(but not to their attributes) It is
possible to use the operators "==", ">
= ", "<", etc. to define this condition.
It can be set any number of such
conditions, joined with logical "and",
or no condition at all.
Property Condition
Intended for sets formed not by primitive
types (classes). This condition defines
a membership of objects in a set
basing on values of their attributes.
Missing Strategy
Serves to define a membership of object in
a set if not all of an object’s attributes
are set.
Connecting Strategy
Serves to define how separate property
conditions will be combined
Type Check Strategy
Defines an opportunity of membership for
objects of classes which are ancestors
for a class of the given set

Conclusion
 Interaction with Service is an iterative Process
 The requirements of user support are:
 Supporting of multiple sets of request parameters
 Adjustable boarders for values of request parameters
 Prioritisation of user requests
 The existing solutions do not fit the requirements
 We have developed own Solution which meets the
formulated requirements
