Does NLP need machine learning?

With NLP, machines can make sense of written or spoken text and perform tasks like translation, keyword extraction, topic classification, and more. But to automate these processes and deliver accurate responses, you’ll need machine learning.

How to classify job titles in Python and NLTK?

Training a software to classify job titles is a multi-text text classification problem. For this task, we can use the Python Natural Language Toolkit (NLTK) and Bayesian classification. First, let’s conce p tualize what a job title represents. Each job has a level of responsibility for some department.

How to do job title analysis in Python?

The job titles are paginated so the only way to get them all is to click on each page. Once the job titles are imported, we can describe the responsibility and department of these jobs. For this project, we will need the Natural Language Toolkit (NLTK). It contains text processing resources, machine learning tools, and more.
