Time, place, result

Semester: spring
Grading: exam
Points: 3.5

Lectures: every Monday 15.00-16.30, room IT-137a
Practical work: every Monday after the lecture: 16.45-17.30

Practical work will give 40% and exam 60% of points underlying the final grade. There will be an optional (hard) third practical work: choosing this will give 60% from labs and 40% from exam.


Practical work

  • two labs on the same theme.
  • optional third lab


First lab

Date: 10 March.

Implement a system which can read html annotated according to the RDFa standard. The data read should be saved and printed in several formats:

  • csv
  • rdf xml syntax

NB! You may not use a ready-made RDFa parser/converter. Instead, use a html/xml parser and build the RDFa converter on top of that. Using xslt is also an OK option. Programming language and the html/xml parser choice is free.

You will have to find suitable annotated html pages to demonstrate your solution.

Additional reading:

You may also look at some practical non-obligatory programming suggestions in Estonian: rdfa esimese praksi soovitusi.

Second lab

Using the results of first lab for rule-based derivation of new information.

Details of the second lab: rule system for tourist suggestions.

Third lab

Third lab is optional. If you do it, it will give additional 20% of points underlying the final grade. There are two alternative ways to do the third lab: select yourself:

  • First alternative: download and use Wordnet to automatically create additional rules used in the second lab. These rules would mostly probably stem from the Wordnet taxonomies. You do not have to create rules for all the wordnet taxonomies: select a sensible subset which would be usable for the second lab.
  • Second alternative: use Attempto to create a system such that you can write rules and/or facts and/or queries for the second lab in restricted english. These restricted english sentences have to be automatically converted to the form usable by Otter/Plan9.

Materials for the exam

Use and read the following


RDF, RDFS, OWL and conversion to 1st order logic
