Objectives, Skills and Learning Outcomes
The "Information Description, Storage and Retrieval" unit assumes as its context the existence of large collections of heterogeneous information which needs to be organized, described, stored and retrieved.
Make the students aware of the main issues in the organization and storage of large data collections.
Make the students familiar with the main concepts in textual information retrieval and their application in retrieval tools.
Explore the semantic web methods and tools, and use web resources and their descriptions in applications that make use of data semantics.
On completion of this course, the student should be able to:
Identify the uses of document markup languages in data repositories and in application support;
Analyze an XML document and show its conformity to a model;
Create models for XML documents;
Interpret the results of document processing with XML-based technologies;
Compare data organization in markup models and other models and explore data migration between models;
Generate a markup model for data in an application domain, and choose an appropriate storage solution for them;
Describe the models used in information retrieval, specifically in web retrieval;
Recognize the various tasks considered in information retrieval;
Apply information retrieval evaluation measures to the comparison of web retrieval tools;
Relate web documents with the metadata that describes or links them;
Treat ontologies as providers of description tools;
Explore the applications which manipulate semantic web information descriptions and create metadata sets for a chosen domain;
Compare semantic web- based services with simpler approaches to resource description.
Introduction to XML and associated technologies: models and document validation; XPath processing and XQuery interrogation.
Text information retrieval; retrieval models; evaluation; web information retrieval.
Information description: semantic web languages; RDF, RDF-Schema, OWL; ontologies for data in a domain.

Admission to Exams
The course has a practical component which results from the execution of projects, to be delivered up to the due dates established in the course plan.
The students are admitted to the final exam if they achieve 50% in each component of the project work. Success in the course requires 40% in each intermediate written test.
The final grade is computed using the formula: GRADE= 60% Projects + 40% Tests.
The Projects component is the result of the practical evaluation and can be obtained:
The project and its workplan must be validated by the course instructors.
None. All students have to complete the projects and present them as scheduled.
Special evaluation (TE, DA, ...)
Distributed evaluation, performed during the semester, is required of all students, regardless of their enrollment status.
Improvement of Final/Distributed Classification
Improving the classification requires a new enrollment in the course, taking the course projects and tests again.
