Objectives

1. BACKGROUND

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.

2. SPECIFIC OBJECTIVES

  1. Make the students aware of the main issues in the organization and storage of large data collections.
  2. Make the students familiar with the main concepts in textual information retrieval and their application in retrieval tools.
  3. Explore the semantic web methods and tools, and use web resources and their descriptions in applications that make use of data semantics.

Learning outcomes and competences

On completion of this course, the student should be able to:

  • Identify data sources in data repositories, online services APIs and user logs;
  • Decide on the quality of the data sources and briefly characterize a selected dataset;
  • Choose the document granularity and a storage model for the dataset;
  • Use data manipulation tools to select appropriate data subsets and to fit the data to their intended applications;
  • 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.

Eligibility for exams

The course has a practical component which results from the execution of projects, to be delivered up to their 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.

Calculation formula of final grade

The final grade is computed using the formula GRADE= 60% Projects + 40% Tests.

The Project component results from the practical evaluation and can be obtained:

  • completing three practical assignments according to the proposed scripts;
  • proposing a semester-long project and reporting its results in the same sessions as the assignments.

The project and its workplan must be validated by the course instructors.

Examinations or Special Assignments

None. All students have to complete the projects and present them as scheduled.

Special assessment (TE, DA, ...)

Distributed evaluation, performed during the semester, is required of all students, regardless of their enrolment status.

Classification improvement

Improving the classification requires a new enrolment in the course, taking the course projects and tests again.
