+# Computations Syntax Lectures: Outline
+
+## Lecture 1
+
+Coursenotes: Chapter 1
+
+Participants' native languages:
+Chinese (2), Dutch, English, Finnish, French (2), Greek, Hebrew, Italian (3),
+Korean, Persian (2), Polish, Portuguese, Romanian (3), Russian, Spanish, Swedish (2),
+Swiss German, West-Assyrian - 24 students, 17 languages + 2 teachers, 1 more language
+
+Formal grammar is no more expected to match natural language exactly
+- analysis: should be wider than the language (we will use UD)
+- generation: should be contained in the language (we will use GF)
+- in both formats, we aim to use universal concepts for many languages
+
+Phrase structure grammars, context-free = BNF, grammar rules, trees
+- example: [english.cf](lecture-01/english.cf)
+- testing grammars in GF: import, generate_random, parse, linearize, visualize_parse, help
+
+
+GF grammars: dividing .cf into abstract and concrete .gf
+- example: [Intro*.gf](lecture-01/)
+- forms of rules: cat, fun, lincat, lin
+- word order switch English-Italian
+- to solve next time:
+
+Experiments in GF:
+- https://cloud.grammaticalframework.org/minibar/minibar.html
+- Grammar: ResourceDemo, Startcat: S
