AI continues to progress and become more complex and precise. With the advent ofgenerative artificial intelligencelarge-scale language models (LLMs) have revolutionized the way companies manage and exploit text data. These sophisticated models, such as GPT-3 or GPT-4, are capable of generating coherent, relevant text from a prompt, opening up new perspectives for diverse applications such as automatic writing, translation, text synthesis and much more.
This evolution has created new use cases around textual data, generating a growing need for high-performance textual data annotation tools and services. Specialist NLP annotation platforms such as Prodigy or UbiAI have had to innovate and reinvent themselves to meet the growing demands of enterprises for natural language processing and analysis. Until now, use cases were relatively simple: for example, companies could develop NLP (for "Natural Language Processing") models using relatively limited quantities of data. Today, these companies are seeking to develop autonomous AI agents capable of interacting naturally with users. Text annotation platforms are therefore more than ever an important tool for data scientists and AI specialists: they not only enable text data to be annotated and categorized, but also enriched and exploited to improve the performance of AI models.
The rise of LLMs has also led to a growing demand for the high-quality annotated text data needed to train and refine these models. Companies are now looking for scalable, accurate text data annotation solutions to meet the needs of their ever-evolving AI projects. NLP annotation platforms therefore play a key role in the development and optimization of generative AI models, providing annotated and enriched textual data to enhance their performance and capabilities.
To help your model interpret human language, you need to give it high-quality data. This data must be processed with the best tools to ensure that it is accurate and that the AI learns under the best conditions. In this article, we offer an introduction to the use of text annotation tools and services for AI. Why are these services important, and what do they cost? What is an LLM? What's the difference between an LLM and an NLP? That's what you'll find out in this post.
We hope this blog post will give you a sufficient understanding of the NLP and LLM development process. You'll understand how AI works and how it has been developed to generate quality content. You'll also understand how data is critical in training machine learning models to your own requirements!

What's the difference between an NLP model and an LLM?
An NLP (Natural Language Processing) model and an LLM (Large Language Model) are both machine learning models designed to process and understand human language, but they differ in terms of size, complexity and capabilities.
An NLP model is a generic term for any computer model capable of analyzing, understanding and generating natural language. These can be relatively simple models, such astopic modeling, or more complex models, such as recurrent neural networks (RNN) or transformers. NLP models can be trained to perform a variety of tasks, such as text classification, named entity extraction, response generation and so on.
An LLM, on the other hand, is a specific type of NLP model characterized by its large size and its ability to process and generate natural language more consistently and accurately than smaller models. LLMs are generally based on transform architecture and are trained on large corpora of textual data. They are capable of capturing complex semantic relationships between words and phrases, enabling them to generate coherent, relevant text from an invitation. Examples of LLMs include OpenAI's GPT-3, Google's BERT and Google's T5.
In short, if you were to remember just one thing: all LLMs are NLP models, but not all NLP models are LLMs. LLMs are NLP models of great size and complexity, designed specifically to process and generate natural language consistently and accurately.
Is it necessary to use text annotation services to develop AI products? Is it essential?
Text annotation services are companies or solutions that help solutions that help label or tag textual data.. This can include activities such as annotating certain words or phrases to identify and describe emotions or topics, or commenting with metadata on the use of language.
This tagged text data is then used in machine learning. It can help computers understand human language more effectively. This is an essential principle for developing virtual assistants that answer our questions, or for other AI projects.
One example of how text annotation is used is in natural language processing (NLP). In computer science, NLP is a field focused on the understanding of natural human language by computers.
Text annotation services provide high-quality training data to teach computers to perform tasks such assentiment analysis, named entity recognition andintention analysis. This is particularly important when AI has to work with different languages.
These services are important and often necessary, for a number of reasons. Here are 3 of the most important:
1. Creating structured data from unstructured text
Annotation transforms text (which has no clear format) into data that a computer can understand.
2. Improving AI accuracy
The more quality data we have, the better an AI can learn a task like text classification, object detection or question answering.
3. Saving time for data scientists and AI experts
If experts annotate data, it means that people working on AI can spend more time creating and improving models. In fact, this is what data scientists should be doing: stop wasting time on data processing, or entrusting these tasks to your interns. Instead, think aboutoutsourcing !
In AI projects, whether understanding speech or working with documents (invoices, pay slips, newspaper extracts, etc.), the use of text annotation tools ensures that models are supplied with data that truly reflects the way people use language. This makes AI more useful and reliable.
For example, suppose a company wants to train models for virtual customer service assistants capable of understanding and answering questions in multiple languages. High-quality, human-annotated text data from reputable and reliable text annotation services can teach these models the critical information they need, including slang and meaning beyond the words themselves. All the subtleties of a language should be crystal clear to an AI model.
How can we determine whether text annotation is suitable for machine learning models?
Text annotation for machine learning models involves several critical steps to ensure that the models work effectively. Here are the key elements of the annotation process:
High-quality training data
The creation of high-quality training data is essential. This involves collecting relevant textual data that is sufficiently diverse to train models capable of understanding various linguistic nuances, including slang and cultural context.
High-quality data contributes significantly to the model's ability to make accurate predictions or analyze sentiment.
Annotation tasks
Different annotation tasks serve different purposes. For example, sentiment analysis helps machines determine positive or negative emotions in text, while entity recognition involves labeling specific text fragments for categorizing information such as names or locations. Intent analysis deciphers the user's intention behind a message.
Tools and technology
Efficient text annotation tools are essential for managing labeling tasks. These tools help streamline the annotation and labeling process by offering features such as automatic label suggestions, which in turn saves time and improves consistency in data labeling.
Expertise in the field
Data annotation needs to be carried out by domain experts (in medicine, finance or agriculture, for example) who understand the context and complexities of the language.
Their expertise is essential, particularly for tasks such as semantic annotation of entities and entity linking, in order to interpret text accurately.
Iterative process
Annotation is an iterative process, involving a cycle of labeling data, training models, evaluating results and fine-tuning annotations according to model performance.
Data Scientists constantly work with the annotated data to adjust the models based on feedback, ensuring that the machine learning model evolves to become more accurate.
Multilingual support
Annotated datasets and annotations must include diverse linguistic datasets to effectively train NLP models. It's ideal to include annotations in many languages, and to have these annotations performed by annotators fluent in that language.
Reliability assurance
The reliability of AI depends on how accurately training data reflects real-world language use.
Text classification, text categorization and document annotation must be carried out meticulously to provide machine learning models with data reflecting real user interactions.
Scalability
With machine learning projects dealing with large volumes of data, the annotation process needs to be scalable. Modern annotation platforms support scalability by enabling large teams of annotators and algorithms to work simultaneously on large datasets.
Overall, appropriate text annotation is fundamental to the development of effective machine learning and NLP models. It requires high-quality datasets, specialized tools, domain expertise and a robust process to enable machines to understand and process human language with high accuracy, ultimately improving AI applications.
How does an NLP annotation tool work, and how do you label textual data?
Annotation tools specialized in natural language processing help prepare the data that enables computers to understand human language. They transform unstructured text, such as the sentences in an e-mail, into structured data that a computer can use.
What tasks can text annotation tools be used for?
Text data collection
The first task that comes to mind is to gather a large amount of textual (or vocal) data from sources such as books, websites, chats or comments from social networks like Facebook or Instagram. This data needs to be sufficiently varied and reproduce reality in the best possible way, in a balanced dataset.
Data processing and annotation tasks
Next, people using the annotation tool (such as Data Labelers) add labels to the data. For each type of content, for example, in sentiment analysis, they assign a comment to fragments of text such as "happy" or "sad". In entity recognition, they highlight names or places, and the relationships between them.
Using labeled data to train the artificial intelligence model
This labeled data is used to teach AI models how to perform tasks such as classifying text and images, or answering questions. The models learn from patterns in the labeled data.
Iterative improvement
After training the models with the data, Data Scientists check the AI's performance. They can make changes to their dataset and label more data to help the AI learn more effectively.
