In the context of computer applications, the need to implement intelligent solutions to increasingly complex problems (such as business intelligence, intelligent control systems, decision support sytems, Internet browsing, etc.) is becoming every time more frequent.

Many of these intelligent solutions are based on the existence of a knowledge base that regulates or affects the performance of computer systems and gives these systems the (distinguishing) character of intelligent.

These knowledge bases are expressed according to some formats, structures and formal representation languages that​​, in some cases, define international standards. The field of "knowledge representation" in this course sets the fundamentals for these formats and languages ​​for knowledge formalization. The field of "knowledge engineering" addresses the learning and practice of techniques and methods for building knowledge bases.

Teaching methodology

Introductory Activities: Introduction of the lecturer, the objectives of the subject, the contents, the teaching methodology, evaluation process, and the supporting material.

Master Session: The lecturer will explain the basic contents of the subject with examples. (S)he will provide the student all the material required to prepare the subject.

Solving problems and exercises in ordinary class: In groups we'll study a tool for knowledge management and we'll do a practical work. Each group will present the results to the lecturer.

Evaluation methodology

(50%) Problems and exercises resolution in ordinary class: Thorough the course there will be several partial tests.

(50%) Objective tests with short questions: Objective tests with short questions every other week of 30 min each. We'll devote one of these tests (this one of 2h) to evaluate the total content of the subject.

The student who don't pass the evaluation, will have a reparatory exam on the full contents of the subject (100% of the final mark).
