Syntactic parsing is a time-consuming task innatural language processing particularlywherea largenumber of text files are beingprocessed. Parsingalgorithms are conventionally designed to operate on a single machine in a sequential fashionand, as a consequence, failto benefit from high performance and parallel computing resources available on the cloud.We designed and implemented a scalable cloud-based architecture supporting parallel and distributed syntactic parsing for large datasets. The main architecture consists of asyntactic parser(constituency and dependency parsing)and a MapReduceframework running onclusters of machines.The resulting cloud-based MapReduce parsing is able to builda map where syntactic trees of the same input file have the same keyand collect into a singlefile containing sentences along with their corresponding trees.Ourexperimental evaluation showsthat the architecture scales wellwith regard to number or processing nodes and number of cores per node.In the fastest tested cloud-based setup, the proposed design performs 7times faster when compared to a localsetup. In summary, this study takes an important step toward providing and evaluating a cloud-hostedsolution for efficient syntactic parsingof natural language data sets consisting of a large number of files.
