General description A materia introduce ao estudante na extracción, avaliación e análise de información presente na Web mediante o uso de tecnoloxías que interpretan a semántica subxacente ao formato dos seus contidos. Neste contexto, capacitaráselle na súa explotación como fonte global de datos, independentemente de cal sexa a súa localización e o dispositivo ou plataforma de acceso, tanto se están expresados en linguaxe natural como en linguaxes directamente interpretables por axentes intelixentes. Trátase en definitiva de facilitar o acceso, compartición e integración de información entre usuarios Web.

Methodologies
Methodologies Description
Problem solving Sessions whose objective is that students acquire certain skills based on the resolution of exercises, case studies and projects that require the student to apply the knowledge and skills developed during the course. These sessions may require the student to present orally the solution to the problems posed. The work carried out by the students can be done individually or in work groups.
Laboratory practice Classes dedicated to the development of practical work involving the resolution of complex problems, and the analysis and design of solutions that constitute a means for their resolution. This activity may require students to present their work orally. The work carried out by the students can be done individually or in work groups.
Mixed objective/subjective test Final exam
Guest lecture / keynote speech Oral exposition complemented with the use of audiovisual media and the introduction of some questions directed to the students, with the purpose of transmitting knowledge and facilitating learning. In addition to the time of oral exposition by the professor, this formative activity requires the student to dedicate some time to prepare and review on their own the materials object of the class.

Personalized attention
Methodologies
Problem solving
Laboratory practice
Description
Monitoring of the development of the practices in the reserved hours of laboratory and attention to the student in the necessary cases of problems of particular difficulty

Assessment comments

It will be necessary to reach 40% of the score in each part.

The evaluation will be considered as not presented when no practical work or final exam is submitted.

Second opportunity

The evaluation will be carried out with the same criteria described above. A new deadline will be opened for the delivery of the practical works, in the event that they are not delivered at the first opportunity.
