@inProceedings{ljunglof-2012-practical-168969, title = {Practical Parsing of Parallel Multiple Context-Free Grammars}, abstract = {We discuss four previously published parsing algorithms for parallell multiple context-free grammar (PMCFG), and argue that they are similar to each other, and implement an Earley-style top-down algorithm. Starting from one of these algorithms, we derive three modifications – one bottom-up and two variants using a left corner filter. An evaluation shows that substantial improvements can be made by using the algorithm that performs best on a given grammar. The algorithms are implemented in Python and released under an open-source licence. }, booktitle = {TAG+11, 11th International Workshop on Tree Adjoining Grammar and Related Formalisms}, author = {Ljunglöf, Peter}, year = {2012}, }
