If you’re looking to extract medical concepts from text using the powerful MetaMap tool, look no further than Pymetamap! This Python wrapper makes it easy to utilize MetaMap’s capabilities in your projects. In this guide, we’ll cover how to install Pymetamap, use it for extraction, and troubleshoot common issues.

Installation Guide

To start using Pymetamap, you’ll first need to install MetaMap. Follow these steps:

• Install MetaMap by visiting MetaMap Installation Page.
• Install Pymetamap using the following command:

python setup.py install

Example Usage

Once you have Pymetamap installed, you can start extracting concepts. Here’s a simple analogy to help understand its functionality:

Think of MetaMap as a chef who specializes in understanding the flavors of various ingredients (words). Each time you give the chef a new dish (sentence), they will analyze it and identify what ingredients make up the dish, presenting you with a list of distinct flavors (concepts).

Creating a MetaMap Instance

To get started, you need to create a MetaMap instance like this:

from pymetamap import MetaMap
mm = MetaMap.get_instance("opt/public/mmbin/metamap12")

Make sure you replace “opt/public/mmbin/metamap12” with the actual path of the MetaMap binary installed on your system.

Using MetaMapLite

If you want to use MetaMapLite instead, create an instance like this:

from pymetamap import MetaMapLite
mm = MetaMapLite.get_instance("opt/public/mm_lite/3.6.2rc3")

Ensure that the MetaMapLite home directory you provide is an absolute path.

Extracting Concepts

Now that you have your instance ready, you can extract concepts from sentences as follows:

sents = ["Heart Attack", "John had a huge heart attack"]
concepts, error = mm.extract_concepts(sents, [1, 2])
for concept in concepts:
    print(concept)

This will output the concepts extracted from the given sentences just like how our chef identifies the distinct flavors in the dishes provided.

Troubleshooting Tips

If you encounter any issues, here are some troubleshooting tips:

• Ensure you have installed MetaMap correctly and that the binary path is correctly referenced in your code.
• Check that you are using Mac or Linux, as this code does not work with Windows.
• If you experience issues with extracting concepts, verify the sentences are well-formed and relevant to MetaMap.
