<h2>What is the UMLS?</h2>
<p>The UMLS, or Unified Medical Language System, is a set of files and software that brings together many health and biomedical vocabularies and standards to enable interoperability between computer systems.</p>
<p>You can use the UMLS to enhance or develop applications, such as electronic health records, classification tools, dictionaries and language translators.</p>

<h2>UMLS in Use</h2>
<p>One powerful use of the UMLS is linking health information, medical terms, drug names, and billing codes across different computer systems. Some examples of this are:</p>
<ul>
<li>Linking terms and codes between your doctor, your pharmacy, and your insurance company</li>
<li>Patient care coordination among several departments within a hospital</li>
</ul>
<p>The UMLS has many other uses, including search engine retrieval, data mining, public health statistics reporting, and terminology research.</p>

<div class="umlsleft"><a name="The_Three_UMLS_Tools"></a>
<h2>The Three UMLS Tools</h2>
<p>The UMLS has three tools, which we call the Knowledge Sources:</p>
<ul>
<li><strong>Metathesaurus</strong>: Terms and codes from many vocabularies, including CPT&reg;, ICD-10-CM, LOINC&reg;, MeSH&reg;, RxNorm, and SNOMED CT&reg;</li>
<li><strong>Semantic Network</strong>: Broad categories (semantic types) and their relationships (semantic relations)</li>
<li><strong>SPECIALIST Lexicon and Lexical Tools</strong>: Natural language processing tools</li>
</ul>
<p>We use the Semantic Network and Lexical Tools to produce the Metathesaurus. Metathesaurus production involves:</p>
<ul>
<li>Processing the terms and codes using the Lexical Tools</li>
<li>Grouping synonymous terms into concepts</li>
<li>Categorizing concepts by semantic types from the Semantic Network</li>
<li>Incorporating relationships and attributes provided by vocabularies</li>
<li>Releasing the data in a common format</li>
</ul>
<p>Although we integrate these tools for Metathesaurus production, you can access them separately or in any combination according to your needs.</p>

<h2>Access the UMLS</h2>
<p>The UMLS Terminology Services (UTS) provides three ways to access the UMLS:</p>
<h3>Web Browsers</h3>
<p>You can search the data through UTS applications:</p>
<ul>
<li><strong>Metathesaurus Browser</strong> - Retrieve UMLS concept information, including CUIs, semantic types, and synonymous terms.</li>
<li><strong>Semantic Network Browser</strong> - View the names, definitions, and hierarchical structure of the Semantic Network.</li>
</ul>
<h3>Local Installation</h3>
<p>To install the UMLS on your computer, download the files through the UTS. The MetamorphoSys tool, included with the downloaded files, allows you to customize the UMLS according to your needs. You can then load your customized data into your own database system, such as MySQL or Oracle, or you may browse your data using the MetamorphoSys RRF browser.</p>
<h3>Web Services APIs</h3>
<p>You can use our application programming interfaces (APIs) to query the UMLS data within your own application.</p>
