How to Part-Of-Speech POS Tag a String in Python

An important part of Natural Language Processing (NLP) is the ability to tag parts of a string with various part-of-speech (POS) tags. This is generally the first step required in the process. To achieve this in today’s example, we will use the Cloudmersive NLP API to perform this complex task for us. We shall install its client as our first step.

pip install git+https://github.com/Cloudmersive/Cloudmersive.APIClient.Python.NLP.git

Now if we call pos_tagger_string_post, we can input our string for processing. Take a look at the following example to get an idea of how that call should look.

from __future__ import print_functionimport timeimport cloudmersive_nlp_api_clientfrom cloudmersive_nlp_api_client.rest import ApiExceptionfrom pprint import pprint# Configure API key authorization: Apikeyconfiguration = cloudmersive_nlp_api_client.Configuration()configuration.api_key['Apikey'] = 'YOUR_API_KEY'# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed# configuration.api_key_prefix['Apikey'] = 'Bearer'# create an instance of the API classapi_instance = cloudmersive_nlp_api_client.PosTaggerStringApi(cloudmersive_nlp_api_client.ApiClient(configuration))input = 'input_example' # str | Input stringtry:# Part-of-speech tag a stringapi_response = api_instance.pos_tagger_string_post(input)pprint(api_response)except ApiException as e:print("Exception when calling PosTaggerStringApi->pos_tagger_string_post: %s\n" % e)

And just like that, you have a POS tagging system! Easy.
