WebIn this paper we describe a modi ed CYK parsing algorithm which has several bene cial properties vs. standard implementations. Our algorithm: 1) Is cache-e cient on standard CPUs; 2) Parallelizes easily and scales smoothly to large processor counts; and 3) Adapts well to cache-less throughput-oriented processors such as graphics processors (GPUs). WebMar 7, 2024 · A natural language parser is a program that figures out which group of words go together (as “phrases”) and which words are the subject or object of a verb. The NLP parser separates a series of text into smaller pieces based on the grammar rules. If a sentence that cannot be parsed may have grammatical errors.
