Coursework

Autores: Oscar Corcho, Asunción Gómez Pérez, Guadalupe Aguado de Cea

To allow students to consolidate knowledge and skills acquired throughout the course some assignments related to each unit have been designed. Students will work in pairs and all the coursework to be done will be related to a specific domain. That domain will be agreed by the teacher and the students. The aim is to enable students to apply the knowledge acquired in the course in order to face new situations and solve real problems. Thus, students will be well prepared to adapt to the continuous technological evolution in this field.

The following table describes the coursework that students will have to prepare for each unit and the technologies that will be used.

Units	Specific Assignments
Unit 1. Introducing the Semantic Web	Define a type of problem where the semantic web technologies can be used and identify the application domain. Reading the TBL paper. Revision of the contents identified as fundamentals in this subject.
Unit 2. Terminological resources	Identify a whole set of terminological resources as possible candidates for the domain application. Compare them and select the most appropriate subset considering the problem to solve.
Unit 4. Ontology Foundations	Define use scenarios in a domain and find available ontologies in that domain. Classify the selected ontologies according to the criteria explained. Compare the overlapping degree of these ontologies with the vocabularies of the selected terminological resources mentioned in Lesson 2.
Unit 5. Semantic Web Languages	Implement a knowledge model of that domain in SESAME. Identify and implement at least 10 queries in SPARQL. Identify the differences between a query in SQL on a DB and the previous in SPARQL
Unit 6. Editors and Reasoners	Use an ontology editor based on description logics (NeOn toolkit, Protégé) to build the knowledge model implemented in Lesson 5. Perform at least 10 inferences using reasoners. Commment on the similarities and differencies, advantages and disadvantages of using a query language against a reasoner. Design and perform scalability and interoperability tests importing the ontologies to the ontology editor mentioned in lesson 4. Report on the usability of the employed tools.
Unit 7. Methodologies used to build ontologies	Identify the life cycle model to be used to build the ontology considering resource reuse. Design and plan the ontology development, the activities to be carried out, the resources to be used, etc.
Unit 8. Ontology Specification activities	Specify the domain ontology to be built, with great detail. Use the specifications to improve the ontology built with the editor mentioned in lesson 6.
Unit 9. Reusing, reingeneering and learning	Reuse non-ontological esources (lexicons, thesauri, etc.) identified in lesson 2 and transform them in ontological resources by re-engineering processes. Reuse the ontological resources identified in lesson 4 and carry out re-engineering processes, if necessary, in order to use them with the selected ontology editor. Integrate these resources with the ontology in the ontology editor in order to provide a new version of the ontology.
Unit 10. Alignments and Mappings	Do mappings between two of the ontologies of the same domain selected in lesson 4. Do mappings between ontological and non-ontological resources.
Unit 3. Multilingalism in ontologies	Using the NeOn Toolkit localization tools, translate the ontology into another language, at least.
Unit 11. Annnotation	Annotate texts, web pages and multimedia documents using the ontology already built and some annotation tools (eg., GATE, MnM, M-OntoMat-Annotizer, Armadillo, AKTive media) Report on the usability of the employed tools.
Unit 12. Semantic access to distributed DBs	Use the R20 language to overlay two DBs with the ontology built. Perform at least 10 queries in each DB. Identify the advantages of R20 and ODEMapster Report on the usability of the employed tools.
Unit 13. Semantic Web Services	No specific assignment has been proposed. Group work: Students will establish relations among the different ontologies built in the different groups. If there are several ontologies of the same domain, they will propose techniques to evaluate them.
Unit 14. Applications	No assignments have been proposed.
