Q61.
What are some of the initial applications of the Estonian semantic interoperability framework?

a.

Automated Web service composition and artifact indexing and discovery

b.

Maintenance of redundant data and database schemata in XML form

c.

Application-specific details and ontological dependencies

d.

Artifact indexing and discovery, automated Web service composition, linking open data, and redundancy detection in Web services

Discuss
Answer: (d).Artifact indexing and discovery, automated Web service composition, linking open data, and redundancy detection in Web services Explanation:The initial applications of the Estonian semantic interoperability framework include artifact indexing and discovery, automated Web service composition, linking open data, and redundancy detection in Web services.
Q62.
Why is linking meta-data to artifacts themselves preferred in the context of ontologies?

a.

To increase the complexity of data sources

b.

To make the sources self-explanatory

c.

To eliminate the need for meta-data

d.

To reduce the quality of decision-making

Discuss
Answer: (b).To make the sources self-explanatory Explanation:Linking meta-data to artifacts themselves is preferred in the context of ontologies to make the sources as self-explanatory as possible, ensuring that the meta-data is closely associated with the artifacts for better understanding and utilization.
Q63.
What are the three attributes defined by SAWSDL for expressing the semantics of schema elements?

a.

Annotation, Description, Reference

b.

ModelReference, LiftingSchemaMapping, LoweringSchemaMapping

c.

SemanticElement, WebServiceDescription, SchemaAnnotation

d.

OntologyMapping, DataModelDescription, SchemaExtension

Discuss
Answer: (b).ModelReference, LiftingSchemaMapping, LoweringSchemaMapping Explanation:SAWSDL defines three attributes for expressing the semantics of schema elements: ModelReference, LiftingSchemaMapping, and LoweringSchemaMapping.
Q64.
What constraint was imposed on the usage of SAWSDL in the Estonian e-government case study regarding the formal definition of semantic concepts?

a.

Semantic concepts must not be formally defined.

b.

Semantic concepts must be defined in any ontology language.

c.

Semantic concepts must be formally defined in OWL DL ontology language.

d.

Semantic concepts must be defined only in RDF format.

Discuss
Answer: (c).Semantic concepts must be formally defined in OWL DL ontology language. Explanation:In the Estonian e-government case study, it is required that the semantic concepts are to be formally defined in OWL DL ontology language.
Q65.
When are references to multiple ontologies allowed for describing the semantics of the same WSDL element in the Estonian e-government case study?

a.

References to multiple ontologies are not allowed.

b.

References to multiple ontologies are allowed only for alternative semantics.

c.

References to multiple ontologies are allowed for alternative semantics and when an annotation is refined by following the RDF graph of an ontology.

d.

References to multiple ontologies are allowed only for alternative semantics in a specific context.

Discuss
Answer: (c).References to multiple ontologies are allowed for alternative semantics and when an annotation is refined by following the RDF graph of an ontology. Explanation:In the Estonian e-government case study, references to multiple ontologies to describe the semantics of the same WSDL element are allowed in two cases: first, for alternative semantics in a specific context, and second, when an annotation is refined by following the RDF graph of an ontology that imports other ontologies.
Q66.
What is the difference between top-level and bottom-level annotations in the context of SAWSDL?

a.

Top-level annotations describe the entire WSDL element, while bottom-level annotations describe parts of the definition of a complex type or element.

b.

Top-level annotations are applied to message parameters, while bottom-level annotations are applied to the entire WSDL element.

c.

Top-level annotations describe the entire ontology, while bottom-level annotations describe specific elements within the ontology.

d.

Top-level annotations are used for ontologies, while bottom-level annotations are used for data structures.

Discuss
Answer: (a).Top-level annotations describe the entire WSDL element, while bottom-level annotations describe parts of the definition of a complex type or element. Explanation:In the context of SAWSDL, top-level annotations describe the entire WSDL element, while bottom-level annotations describe parts of the definition of a complex type or element within the WSDL element.
Q67.
What is the main concern in services and data definitions from the annotation point of view?

a.

Data structure

b.

Data semantics

c.

Legacy systems

d.

Data modeling

Discuss
Answer: (b).Data semantics Explanation:The main concern in services and data definitions from the annotation point of view is their data semantics.
Q68.
In Pattern 1 (URIdtp), when is a reference to a data-type property in an ontology sufficient for annotation?

a.

When the data attribute is used for a wide range of settings

b.

When the data attribute is used only in specific data sets

c.

When the data attribute is used for legacy systems

d.

When the data attribute is domain-specific

Discuss
Answer: (a).When the data attribute is used for a wide range of settings Explanation:In Pattern 1 (URIdtp), a reference to a data-type property in an ontology is sufficient for annotation when the data attribute is used for a wide range of settings.
Q69.
What should be considered when writing one-element annotations using Pattern 1 (URIdtp)?

a.

The subject of the attribute should comply with the domain of the data-type property

b.

The subject of the attribute should be generic

c.

The attribute should have a restricted domain

d.

The attribute should be related to legacy systems

Discuss
Answer: (a).The subject of the attribute should comply with the domain of the data-type property Explanation:When writing one-element annotations using Pattern 1 (URIdtp), the subject of the attribute should comply with the domain of the data-type property.
Q70.
In which cases should Pattern 1 (URIdtp) be applied for semantic annotations?

a.

When the data attribute is domain-specific

b.

When the data attribute is used for very specific data sets and contexts

c.

When there is no need to distinguish classes in ontologies

d.

When the data attribute is related to legacy systems

Discuss
Answer: (c).When there is no need to distinguish classes in ontologies Explanation:Pattern 1 (URIdtp) should be applied for semantic annotations in cases where there is no need to distinguish classes in ontologies.
