The concept of social networks is widely used to model mutual relationships between people (but also between other objects like chemical compounds). Intriguing problems from this area range from finding important structural patterns that influence interaction among the considered actors across sentiment analysis that studies people´s opinions, emotions, and attitudes to the analysis and evolution of the network structure itself. Recently, the trends have shifted rather towards online social networks (e.g., Facebook, LinkedIn and MySpace) which allow for efficient data collection.
Aim of the course -
Last update: RNDr. Jan Hric (07.05.2018)

The course reviews fundamental paradigms and algorithms used in the area of social networks. An important part of the lecture/seminar will represent the design and implementation of an own application in order to facilitate deeper understanding of both the social networks and the means applicable to their analysis. Knowledge at the extent of the bachelors´ course NDBI025 Database systems is expected as well as knowledge of the Python language at least on the level of the introductory course in programming for year 1 of the bachelor study program.

The course is given (only) in English.

A) The lab

Step by step, in an accompanying Moodle course there will be published assignments and quizzes.

Assignments:

Each assignment has a deadline till which the assignment should be submitted for grading. A draft solution of an assignment can be edited at any time, but the time of submission is the time you click the button "Submit assignment". After clicking this button you cannot edit your submission anymore, but you can ask (per e-mail) your teacher to return the assignment back into the draft state. Each submitted assignment will be graded by the teacher with 0–10 points. During the semester, you will solve 3 assignments.

A typical solution for an assignment will consist of a text — a description of the solution — and a code of a program/script used for solving the assignment. Submit your texts as a PDF-file or alternatively as an RTF-file. The source codes should be submitted as plain ASCII files.

Warning: If N≥2 participants of the course will submit solutions which are very similar or identical, all these solutions will be considered as a single solution. The solution will be graded by B points according to its quality and all students who submitted it will obtain only the integer part of the value B/N points.

Quizzes:

Beside the assignments, you will solve several on-line quizzes for at most 20 points altogether. Each quiz will have set up also a deadline. In contrast to assignments, it will be not possible to solve any quiz after its deadline.

For obtaining credits for the lab it is necessary:

  1. To solve all the assignments and to obtain at least 1 point for each solution. WARNING: late submission of a solution will be penalized by 1 point decrease for each started week of the delay after the deadline.
  2. To prepare and to present a term project in the lab in the last week of the term or on a date (during the following exam period) that will be set up in the lab within the last week of the term. Subject for the project will be discussed in a lab in the middle of this term. Each project will be graded up to 15 points according to its quality.

The quizzes are not among the necessary conditions for obtaining credits for the lab. During labs, it is possible to obtain additional points

  • for demonstrating a solution of a problem assigned during a lab — 1 point,
  • for demonstrating a solution submitted as a solutions for an assignment in Moodle (after its deadline) — the integer part of the half of the number of point awarded for the solution (after evaluating by the teacher)

Except for the additional points, it is possible to obtain up to 65 points. All points obtained during labs will be accounted for up to 40% of the final score of the exam. However, when a student will obtain more than 65 points within labs (counting also additional points), these points will still account for only 40% of the final score of the exam.

Continuous work throughout the whole term is required to obtain the credits, therefore there will be no additional possibilities to acquire them later.

B) The lecture

The lecture will be given once per week according to the schedule. As already mentioned above, points acquired within the labs will account for up to 40% of the final score for the exam. Further, there will be one written test which will be written during a lecture. The date for the written test will be set up within the first week of the semester and published in the accompanying Moodle course.

This test will be graded with 0–15% towards the final score. The exam at the end of this term will add up to the remaining 45% to the final score. The following table gives the final grade according to achieved score:

grade 1 grade 2 grade 3 failure
100%–86% 85%–71% 71%–56% less than 56%

Requirements to the exam -
Last update: doc. RNDr. Iveta Mrázová, CSc. (27.05.2020)

The exam consists of a written and oral part. The written part precedes the oral part. Failing the written part impacts failing the whole exam, i.e. the exam will be classified by the grade 4 (failed) and the exam will not continue with the oral part. When failing the oral part the next (reparative) attempt will consist again of both the written and oral parts. The final grade of the exam is set based on points awarded for the written and oral parts of the exam as well as on the points obtained for student’s work throughout the semester - see Course completion requirements.

The written part of the exam consists of three questions related to the syllabus of the lecture and/or material covered during the lab classes.

The requirements for the exam correspond to the syllabus of the lecture within the extent presented in the classes. In order to take part in the exam, it is necessary to obtain Final course credit.
