On a scale of 1 to 5, where 1 means "strongly disagree" and 5 means "strongly agree" please rate and comment on the following:

• 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. 5
• 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. 5
• It was an appropriate unit for a page (it shouldn't be split into different topics or merged with another page). 5
• It links to appropriate other pages in the wiki. 5
• 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. 5
• This page should be highlighted as an exemplary page for others to emulate. 5

If I was grading it out of 20, I would give it: 19

The page is full of detail and definitions. It does a good job of explaining PCFGs and the examples are useful. I have only minor edits to suggest.

• The sentence “This article discusses Probabilistic Context Free Grammars (PCFGs)” in the introduction is the same sentence as in the abstract. I don’t think it’s necessary as the first sentence in the introduction.
• “Title” should probably be changed to be "Probabilistic Context Free Grammars".
