Top 30 NLP Use Cases in 2024: Comprehensive Guide

ByPaul Christiano Last Update on

Natural language processing (NLP) enables computers to understand, interpret, and manipulate human language. Although machines still face challenges in comprehending the complexity and nuance of human communication, NLP has countless valuable applications across industries. In this comprehensive guide, we outline the top 30 business use cases of NLP in 2024.

Overview of NLP

NLP combines computational linguistics and machine learning to process natural language. Its key capabilities include:

  • Sentiment analysis – Identifying subjective information and emotional tones in text.
  • Intent recognition – Determining the purpose or goal behind user queries.
  • Named entity recognition (NER) – Extracting and classifying key information like people, locations, organizations.
  • Language translation – Converting text or audio from one language to another.
  • Speech recognition – Transcribing spoken language into text.
  • Text summarization – Generating concise overviews of long content.

NLP enables machines to parse human communication on massive scales for actionable insights. It is a versatile technology that can be applied to transform everything from customer service to clinical diagnostics.

General NLP Applications

Before diving into industry-specific use cases, let‘s look at some common NLP applications relevant across sectors.

1. Translation

One of the most popular uses of NLP is automated translation. By analyzing parallel texts and linguistic patterns, NLP models can translate written and spoken language between pairs of over 100 languages. Top providers like Google Translate and DeepL continue to push the boundaries of quality and coverage.

2. Autocorrect

Autocorrect automatically identifies misspellings in text and suggests the most likely corrections based on statistical language models. All major mobile keyboards now feature autocorrect powered by NLP.

3. Autocomplete

Autocomplete predicts the most likely words or phrases to follow existing text. It works by scanning for patterns in large bodies of reference texts. Autocomplete streamlines input tasks like search and drafting documents.

4. Conversational AI

Conversational AI like chatbots and voice assistants use NLP to understand user intents and have natural dialogues. Key techniques like intent recognition, named entity extraction, and response generation enable rich conversational experiences across voice and text channels.

5. Speech Recognition

Speech recognition converts spoken language into text by analyzing phonetic components and linguistic patterns. It powers voice assistants, speech-to-text dictation software, and transcription tools.

6. Text Summarization

Text summarization generates concise overviews of long content by identifying key information and relationships between concepts. It condenses documents for quicker reading while preserving overall meaning.

7. Language Models

Language models like GPT-3 use deep learning to generate remarkably human-like text based on an initial prompt. They can produce everything from conversational dialogues to creative prose and even code.

Retail & Ecommerce NLP Use Cases

NLP delivers a wealth of benefits for improving customer experiences and informing business decisions in retail and ecommerce.

8. Customer Service Chatbots

Intelligent chatbots leverage NLP to understand customer issues and provide automated resolutions through conversational dialogues. They can replace tedious FAQs, taking the burden off human agents.

9. In-store Assistance

In-store bots assist shoppers through NLP-powered conversations. They can provide recommendations, answer product questions, check inventory, and more.

10. Market Intelligence

By analyzing customer sentiment across reviews, social media, forums, and surveys, NLP furthers market intelligence on perceptions of brands, products, and emerging trends.

11. Semantic Product Search

Semantic search uses NLP to interpret the meaning behind queries, improving results relevancy. This provides a better customer experience than conventional keyword-based search.

Healthcare NLP Use Cases

NLP is indispensable for extracting insights from unstructured clinical data and automating healthcare workflows.

12. Clinical Documentation

NLP assists clinical documentation by extracting information from unstructured sources like doctors‘ notes, scanned reports, and dictations to populate electronic health records. This reduces administrative loads on healthcare staff.

13. Medical Coding

Computer-assisted coding tools use NLP to analyze health records and assign standard codes for procedures, diagnoses, symptoms, and more to streamline billing and recordkeeping.

14. Clinical Trial Matching

By screening medical histories against trial criteria specified in plain language, NLP algorithms can identify patients eligible for certain clinical trials. This automates and scales patient recruitment.

15. Diagnostic Support

NLP can extract symptoms, medical history, test results, and other health data from patient records to provide clinical decision support. Although not definitive, these insights aid human clinicians.

16. Virtual Health Assistants

Chatbots and voice assistants created for healthcare settings use NLP to engage patients, answer health questions, take symptom reports, provide triage advice, and more while maintaining privacy.

Banking & Finance NLP Use Cases

NLP enables new levels of efficiency, personalization, and security across banking and finance.

17. Conversational Banking

Banking chatbots and voice assistants apply NLP to deliver personalized service, recommend products, provide account updates, and handle transactions through natural conversations.

18. Credit Scoring

By extracting unstructured data from documents like loan applications, NLP supplements traditional credit score models with further insights on creditworthiness based on language patterns.

19. Fraud Detection

Analyzing written communications for semantic anomalies helps identify financial frauds like deceptive claims, money laundering, and identity theft earlier. NLP strengthens fraud prevention.

20. Financial Report Generation

Systems can ingest earnings reports, financial statements, client documents, and other unstructured data sources to auto-generate financial reports and executive summaries using NLP.

Insurance NLP Use Cases

NLP enables insurance providers to cut costs and improve customer satisfaction through automation.

21. Claims Processing

NLP extracts key details from claims documents, assessments, and case notes to automatically populate relevant information into claims management systems. This reduces manual data entry.

22. Policy Recommendations

By analyzing client profiles and application questionnaires, NLP models can suggest the most suitable policies while conversational bots answer applicant questions in plain language.

23. Risk Assessment

NLP augments risk models by scanning informal documentation like email, instant messages, notes, etc. for undisclosed activities that may significantly alter risk profiles.

HR NLP Use Cases

NLP improves efficiency, accuracy, and fairness across the talent management lifecycle.

24. Resume Screening

Intelligent screening tools apply NLP to extract relevant details from resumes and cover letters to automatically flag qualified candidates for open positions.

25. Interview Analysis

NLP techniques analyze video, audio, and text interviews to develop insights on candidates beyond just answers to preset questions. This results in more data-driven hiring decisions.

26. Employee Sentiment Analysis

Analyzing unstructured data like employee feedback and public social media posts using NLP provides HR departments valuable insights into company culture, morale, and potential issues.

27. Training Needs Assessment

By monitoring everyday workplace communications, NLP can identify knowledge gaps and emerging needs to shape more personalized, relevant employee training programs.

Cybersecurity NLP Use Cases

NLP gives security analysts deeper awareness of threats within enormous volumes of unstructured data.

28. Phishing Email Detection

By analyzing email content, structure, links, attachments, and origins, NLP models can reliably identify malicious phishing emails and spam to block threats.

29. Insider Threat Detection

Scanning communications channels like email, IMs, and documents using NLP helps detect potential internal threats through behavioral patterns and language anomalies.

30. Log Analysis

Parsing application and network logs with NLP extracts useful details that may signify emerging attacks otherwise buried in massive log data. This bolsters threat detection.
