Time, place, result

Semester: spring
Grading: exam
Points: 3.5

Lectures: every Monday 12.00-13.30, room IT-137a
Practical work: Mondays on odd weeks 10.00-11.30, room IT-213H

Practical work will give 40% and exam 60% of points underlying the final grade.

Practical work

There are two labs on the same theme and an optional third lab.

First lab

The main goal of the first lab is to web-scrape data from the public sources using search engines and simple text analysis/statistics. Details in Teadmised first lab 2011. The lab should be completed by March, later presentation will cut the points to half.

Second lab

The main goal of the second lab is to augment data obtained from the first lab by writing and using probabilistic rules with a rule engine. The lab should be finished by 21 May, details will be given in the beginning of March.

Optional third lab

The optional third lab can be done in parallel with the second. It will be a relatively complex lab: successful passing will give additional 20 points, thus the weight of the exam is diminished from 60% to 40% of the overall score. The lab should be finished by 21 May, details will be given in the beginning of March.

Course structure

We start with representing and converting facts, continue to rules, first monotonic, then probabilistic and nonmonotonic, then look into search and indexing of complex information, and finally, some learning.

Intro and paradigms of knowledge representation

  • Declarative and procedural representations

Rules in logic: apps in planning, robotics, ...

  • propositional, first order, higher order
  • semantics/models
  • proofs and deriving new information
  • automated reasoning
