HomeBlogData ScienceTop 10 NLP Techniques for Data Scientists in 2024
Natural Language Processing is a popular processing technique that focuses on the interaction between human language and computers and aims to improve this communication drastically. Computer engineers use these techniques and NLP skills to analyze, understand, and generate natural languages like text or speech. Some commonly used NLP techniques include tokenization, POS tagging, NER, sentiment analysis, text classification, language modeling, and machine translation. Along with having NLP skills, going for Data Science certification programs will support you in absorbing the essential knowledge and transitioning to Data Science roles without hassles.
Natural Language Processing is a newly introduced field in recent years and can be considered a branch of data science. It combines artificial intelligence that focuses computer software engineers on enabling computers to understand, interpret, and generate human language. In simpler words, NLP is the technology that helps computers to come out of their coding languages and interact with humans using easily understandable natural language, such as text or speech.
This branch of data science combines various techniques and understanding from computer science, linguistics, mathematics, and psychology. Compared to the other segments, it is slightly complicated as it is new. The main goal of NLP techniques is to ensure that computers can efficiently process and analyze human language data. In recent years, the field of NLP has advanced significantly due to the sudden shift in the world and more focus on the digit world. Today, NLP is used in various applications, such as virtual assistants, chatbots, customer service systems, recommendation systems, and language translation tools.
The roles and responsibilities of an NLP (Natural Language Processing) engineer in data science can significantly vary. There are several factors due to which this can happen depending on the organization and specific job requirements. However, some typical roles and responsibilities of an NLP engineer include:
Developing and Implementing NLP Algorithms and Model Analysis
NLP engineers are responsible for developing and implementing algorithms. They must test models that can process natural language data, such as text or speech, and extract meaningful insights.
Data Preprocessing and Cleaning
NLP engineers are responsible for preprocessing and cleaning natural language data to make it usable for analysis. This can involve tasks such as tokenization, stemming, and stop-word removal.
Designing and Training NLP Models
NLP engineers are responsible for developing and training models. They commonly use machine learning techniques, which help the software or application perform tasks such as text classification, sentiment analysis, and machine translation.
Evaluating and Improving NLP Models
NLP engineers are responsible for assessing the performance of NLP models and continuously improving them based on the results.
Collaborating with Cross-functional Teams
They generally need to work closely with other teams of the computer service segment in the company, such as data scientists, software developers, and business analysts. This helps them to develop and implement NLP solutions that meet the organization's needs.
Staying up-to-date with Industry Trends and Advancements
This is one of the most important factors to be considered by NLP engineers. It helps them apply the recent advancements to improve the performance of NLP models and solutions.
Several NLP techniques in data science are commonly used in machine learning and artificial intelligence. Combining these techniques has enabled the development of sophisticated NLP systems to process and analyze natural language data to extract valuable insights. Some of the top NLP techniques include:
This NLP technique involves breaking down a text into smaller units, such as words or sentences to enable further analysis. One of the most common examples of tokenization is breaking down credit card numbers into short values. This helps in easy and secure data transfer and offers the users privacy. In NLP, tokenization is used to break sentences into easily understandable fragments.
This identifies and categorizes named entities such as people, places, organizations, and dates in a text. NER is the most basic technique that is being used in the field of data science.
This enables the software to segregate data easily by noting different parts of speech. In a way, it can be said that POS helps in labeling each part of the sentence into separate parts and then analyzing them individually for better understanding.
This NLP technique determines the sentiment or overall attitude expressed in a text, such as positive, negative, or neutral. This tool is highly beneficial in customer survey forms and data analysis during reviews.
This technique involves assigning a text to one or more predefined categories. It helps in processing data easily, based on its content, such as spam or not spam, news or opinion, and so on.
There are many other NLP skills that computer engineers can master in the field of data science to polish and add to the section of NLP skills resumes. These skills also help the recruiter understand your knowledge in the parallel streams of computer science, which helps in better understanding. There are several NLP training courses you can take to upgrade and enhance your resume. Below are some of the skills that you must consider:
