Critique

   The topic is relevant for the course. 5
   The writing is clear and the English is good. 5
   The page is written at an appropriate level for CPSC 522 students (where the students have diverse backgrounds). 5
   The formalism (definitions, mathematics) was well chosen to make the page easier to understand. 5
   The abstract is a concise and clear summary. 5
   There were appropriate (original) examples that helped make the topic clear. 5
   There was appropriate use of (pseudo-) code. 3 (Although there wasn't pseudocode, given what you covered it wasn't really needed. Could be helpful if the page is expanded though.)
   It had a good coverage of representations, semantics, inference and learning (as appropriate for the topic). 5
   It is correct. 5
   It was neither too short nor too long for the topic. 2 (It would be nice to expand the page a bit, especially with such a broad topic. Maybe the page could expand some of the syntactic/semantic tasks described earlier?)
   It was an appropriate unit for a page (it shouldn't be split into different topics or merged with another page). 3 (This page could probably be split up a bit into a few different pages, each of the syntactic/semantic tasks could probably just be their own page. Although I do think the page works as a broad intro on its own as well.)
   It links to appropriate other pages in the wiki. 4
   The references and links to external pages are well chosen. 5
   I would recommend this page to someone who wanted to find out about the topic. 4
   This page should be highlighted as an exemplary page for others to emulate. 4

If I was grading it out of 20, I would give it: 16 (I think it just needs to be expanded a little, but overall it's a good intro to the subject)
