Revision with unchanged content. The world wide flood of information makes it most important to use effective tools to extract and condense key information. Information Extraction (IE) is a section of Natural Language Processing (NLP) and is used to extract information from text. The Unified Medical Language System (UMLS) combines a huge variety of source vocabularies, terminologies, and ontologies and covers numerous themes in medicine. The UMLSint package was developed to break down the complex data structure of UMLS and MetaMap Transfer (MMTx). The package gets as an input a sentence of medical text and returns attributes of interest from the UMLS. The information consists of factual knowledge from the Metathesaurus and information generated by the MMTx tool. The MMTx tool is used to create logical elements and gather information about the lexical and morphological structure. The purpose of this book is to enable IE systems, which process medical text, an easier access to the knowledge base named UMLS. This book is contributed to researchers in the fields of Medicine and Computer Science.
