Target skills and knowledge: Critical and advanced skills in the conception, design, implementation and evaluation of information retrieval systems (IRS) and search engines.
Examination methods: 1. Project on a topic chosen in agreement with the teacher and with a seminar presentation.
2. Written exam with questions about all course contents.
3. Possible oral integration.
Assessment criteria: The final exam allows to verify the acquisition of skills related to the ability to evaluate, conceive, design, reengineer, implement and manage information retrieval systems and search engines.
The project serves to test the ability to apply the acquired skills in an experimental way.
Course unit contents: Information retrieval systems and services are pervasive systems that are used every day in information acquisition, administrative management, acquisition of skills, entertainment and communication by millions of experienced and final users. Search engines and information retrieval systems handle large amounts of information, documents and digital resources (big data).

Search engines are the most popular information retrieval tools used to acquire information on people, events and scientific results. Thanks to the results obtained and the information acquired through the search engines, decisions are made and professional and personal activities are carried out.

Information retrieval tools are also included in the various social media (social media) that are used every day for professional and personal purposes by users all over the world and all those systems that allow to retrieve information from e-mail messages, documents and archives on permanent storage devices used in the various information processing tools that people today have in their personal use.

The course contents allow to acquire skills for the conception, design, implementation and evaluation of information retrieval systems and search engines. The presentation of the contents is divided into the following parts:
- Introductory elements (overview) for the representation, management and automatic retrieval of information in digital form
- Indexing: data structures suitable for obtaining information
- Models and systems for information retrieval
- Evaluation: experimental collections, measures of effectiveness and efficiency
- Web search: Web structure, queries and users, Web Agents (Web Crawlers, Crawlers), Search Engine Optimization (SEO).
Planned learning activities and teaching methods: The teaching is based on lectures and experimental activities.
Attendance at lessons is strongly recommended, because the course is designed for students who regularly attend classes, follow the experimental activities of the course and realize the project.
Information regarding the diary of lessons, teaching materials, deadlines and methods of examination are made available to the students in Moodle and/or on the Web.
Additional notes about suggested reading: The study materials are made available in Moodle and/or on the Web.
