Top NLP Techniques We Use to Build Custom AI Solutions
We specialize in NLP techniques for text analysis, sentiment analysis, and AI-powered solutions to drive business growth and efficiency.
Tokenization & Stop Word Removal
Tokenization breaks down text into smaller units—like words or sentences—making it easier for machines to analyze language. Combined with stop word removal, this step filters out non-essential words like “is,” “the,” and “at” to reduce noise. Together, they clean and prepare data for downstream NLP tasks.
Part-of-Speech Tagging & Lemmatization
POS tagging assigns grammatical roles (noun, verb, adjective), allowing models to understand the structure of sentences. Lemmatization then reduces words to their dictionary form (e.g., “running” → “run”). This duo strengthens language understanding and enhances model performance.
Named Entity Recognition (NER)
NER identifies and labels key entities in text—such as names, organizations, dates, and places. It’s crucial for extracting structured data from unstructured content and supports applications in legal tech, finance, healthcare, and chatbots.
Text Summarization & Machine Translation
Text summarization condenses long documents into concise, readable summaries, while machine translation converts text between languages. Together, they power multilingual, time-saving applications in news, legal, healthcare, and eCommerce.
Sentiment Analysis
Sentiment analysis detects whether a piece of text expresses a positive, negative, or neutral emotion. Businesses use it to analyze customer reviews, monitor brand reputation, and respond to public sentiment in real time.
Text Classification
Text classification categorizes text into relevant labels like topic, sentiment, or intent. It automates the organization of content, detects spam or risk, and enables intelligent routing in support systems and content platforms.

Important Natural Language Processing (NLP) Models
Leading Natural Language Processing (NLP) models for AI-driven text analysis, language understanding, and automated solutions to enhance business operations.
These foundational NLP models are powering today’s most advanced language-based applications—from chatbots and search engines to document automation and content generation.
BERT (Bidirectional Encoder Representations from Transformers)
Developed by Google, BERT understands language by looking at words in both directions (before and after), making it highly effective for tasks like question answering, sentiment analysis, and classification.
GPT (Generative Pre-trained Transformer)
Created by OpenAI, GPT models like GPT-3 and GPT-4 are known for their ability to generate fluent, human-like text. They’re used in chatbots, writing tools, virtual agents, and creative applications.
Roberta (Robustly Optimized BERT Pretraining Approach)
A fine-tuned version of BERT by Facebook AI, RoBERTa delivers improved performance across a wide range of NLP benchmarks and is widely used in enterprise solutions for classification, NER, and more.
T5 (Text-to-Text Transfer Transformer)
Google’s T5 treats every NLP task as a text-to-text problem. Whether you're translating languages, summarizing documents, or answering questions, T5 provides one unified, powerful framework.
XLNet
XLNet enhances BERT by capturing both context and word order, resulting in better understanding of sentence structure. It outperforms in tasks that require complex reasoning and comprehension.
Distil BERT
A smaller, faster version of BERT that retains 95% of its performance with significantly reduced size and speed—ideal for mobile apps and low-latency applications.
ALBERT (A Lite BERT)
Designed for scalability and efficiency, ALBERT reduces the size of BERT while maintaining accuracy, making it ideal for high-performance NLP with limited computing power.
Llama (Large Language Model Meta AI)
Developed by Meta, LLaMA is an open-source language model designed for high efficiency in both research and production. It’s capable of powering a wide range of advanced NLP use cases.
Bloom
An open multilingual model trained to generate and understand text in over 40 languages. Bloom supports global, inclusive AI applications—from translation to cross-cultural communication.

How Does Natural Language Processing (NLP) Work?
Text Preprocessing
The process begins by cleaning and preparing the raw text. This includes removing noise, normalizing the content, and breaking it down into manageable pieces to ensure it’s ready for analysis.
Syntactic Analysis
Next, the system analyzes the grammatical structure of the text. It understands how words are arranged in a sentence and how they relate to each other to form meaningful phrases.
Semantic Analysis
At this stage, the system focuses on understanding the meaning behind the words. It identifies important entities, resolves word ambiguities, and interprets the overall context of the sentence.
Feature Extraction
Once the meaning is understood, the text is converted into a numerical format that machine learning models can process. This helps the system learn patterns and relationships in the language data.
Model Processing
The numerical data is passed through an NLP model trained for specific tasks such as classification, sentiment detection, or text generation. This is where the machine makes intelligent decisions based on the input.
Output Generation
Finally, the system delivers the result in a human-readable form. This could be a chatbot response, a translated sentence, a summarized article, or a classification label—depending on the application.
FAQs
Natural Language Processing (NLP) is a field of artificial intelligence that enables machines to understand, interpret, and respond to human language. It works by combining linguistics, machine learning, and deep learning to process text or speech data.

This was one of my best experiences on elance. Ash was great to work with! They completed the project ahead of time and met all my expectations.
Great design, simple to use and easy to use backend. I am very happy with the outcome and would recommend them to anything reading this. Great communication and very professional! The reason elance works is because of people like this. I will 100% try to work with them in future projects!
Joe Sarkis
CEO
AleaIT did a great job on a fairly complicated website project. They were able to both listen to my ideas and provide suggestions of their own, and once direction was agreed upon they executed very well. No project is perfect, but where we had surprises or misunderstandings, they regularly “stepped up” to help the project get back on track, and more than once they approved scope changes that resulted in a better deliverable.
Frank,
CEO
The team at ALEA are willing go above and beyond to get the job done. They stick to budget and give timely information. Willing to advise on new ideas and improvements to the original brief; they have been refreshing to work with. Solid communication backed up with skills and expertise. We have worked together with a range of technologies including PHP, XML, html, and css, and eBay API. Highly Recommended.
