 ====== CFGs and SCFGs ======
+===== Algorithms =====
+  * Intersecting a CFG with a regular language
+    * [[https://aclanthology.org/W11-4408.pdf|Hanneforth 2011 - A Practical Algorithm for Intersecting Weighted Context-free Grammars with Finite-State Automata]]
+    * Common to use the Bar-Hillel construction, see [[https://www.cis.uni-muenchen.de/~fraser/2011_seminar/syntax_lecture1.pdf|here]]
 ===== Recent Applications =====
