ChatGPT and the company that developed it, OpenAI, are on a tear. The rate of user adoption puts even social media behemoths like TikTok and Facebook to shame. The Chatbot AI platform has gained more than 100 million users within the first two months of its launch. And has more than 13 million daily visitors as of 2023. and there is powerful tech behind all this hype.

ChatGPT uses GPT-3 technology which is part of a category of AI known as Large Language Models. And it is not their first rodeo shaping up the practice of law! The underlying tech of large language models enables ChatGPT to create text that feels human. But this is just the latest in an evolution in LLM development to supercharge legal tech.

LLMs like BERT and MBERT are supercharging search, machine translation and even image classification today at Reveal. Building the foundation for the current AI revolution we find ourselves in today. The evolution of LLMs has helped Reveal empower electronic discovery professionals with better, faster, smarter AI-powered solutions.

In this blog post, we will dig into the AI known as LLM and how it's revolutionizing the eDiscovery process for lawyers everywhere. We'll also take a playful and irreverent look at how Reveal is shaking up the legal technology world with their innovative use of LLMs. As well as what the LLM powered future of legal tech might look like.

So, sit back, grab a cup of coffee, and get ready to discover how LLMS are taking legal tech to the next level.

What are Large Language Models, and Why Should eDiscovery Care?

Large language processing was a breakthrough in artificial intelligence (AI). LLMs build intelligent systems with a richer understanding of language than ever before. Large pre-trained Transformer language models, or simply LLMs, vastly extend the capabilities of what systems can do with text.

Large Language Model is basically a fancy way of saying a super-smart AI technology that can understand and generate human language leveraging vast text-based data sets. Think of it like a machine learning algorithm version of Sherlock Holmes. Rather than starting at zero each time, the LLMs can build models that are informed by a vast wealth of human-generated content.

And this is lightyears beyond "spellcheck" or the editor “Hemingway” that I will use to edit this blog. These things are seriously powerful. And they're changing the game in fields like eDiscovery, where lawyers are facing a tsunami of data in their search for evidence.

Transformers, Not Just Saturday Morning Cartoons

There are a variety of LLM AI tools and models available today. Each with varying architectures and capabilities. ChatGPT is part of a subgroup of LLMs known as transformer models. And no these are not like that robot from Saturday morning cartoons growing up.

Transformer models are a type of neural network architecture that was first introduced in 2017. LLMs are used in natural language processing tasks. These include language modeling, machine translation, and text classification. They are known for their ability to capture long-range dependencies and have become the dominant architecture for large-scale language modeling.

Shortly after the first paper was written on transformer models, Google introduced a new open-source language representation model they called “BERT.” BERT (Bidirectional Encoder Representations from Transformers) is a pre-trained natural language processing (NLP) model that leverages a deep neural network to represent the meaning and context of text. The multilingual version MBERT was also developed and trained in 104 languages. MBERT does more than translate, it understands how content in different languages is semantically related.

What is BERT And Why Should I Care?

As a language model, BERT analyzes text and lots of it. It also analyzes the text backwards and forwards. From this analysis, BERT or MBERT predicts any word in a sentence or body of text. This is known as a Masked Language model approach.

In a recent article on Bert and MBERT use by reveal George Socha described Bert as follows:

BERT is a form of deep learning natural language processing that can jump-start your review. It does this via a more nuanced “understanding” of text than is achievable with traditional machine learning techniques. BERT arrives at this understanding by looking beyond individual words to those words’ context. MBERT takes BERT one critical step farther. MBERT is the multilingual version of BERT, trained to work with 104 languages.

BERT marked a huge leap forward in the accuracy of Language models. “Previous models have been stuck at 65% accuracy for decades, but now a standard BERT based (LLM) model is able to do this in a reasonable time (milliseconds) with an 85% - 90% accuracy.” According to a recent Forbes article.

Bert in the Wild

The use of LLMS like the use of AI generally is widespread. Use cases of BERT and MBERT technology run the gamut in our personal and professional lives. These LLMs are streamlining decision making in film, customer service and social media to name a few.

  • BERT the Movie Critic: Movie studios can analyze large amounts of text data such as movie reviews, social media posts, and news articles to predict how well a movie will perform at the box office. Studios invest hundreds of millions in developing films and no one them to flop!
  • mBERT the Polyglot: MBERT improves the accuracy and quality of translations. MBERT understands the relationship between words and sentences in both the source and target languages. BERT considers the context and meaning of the words and phrases. This helps it to produce more accurate and nuanced translations.
  • BERT at your Service: BERT is helping to power chatbots focused on customer service. For example, a customer may ask a question about a product, and the BERT-powered chatbot understands the customer's intent and provide an appropriate response.
  • BERT the Assistant: BERT is also being used to power virtual assistants like Amazon Alexa. BERT helps these virtual assistants to provide more helpful and personalized responses to users. BERT helps ALEXA understand the nuances of natural language. One cool example: a user asks about the weather; the virtual assistant can use BERT to understand the user's location and provide a localized weather forecast.
  • mBERT all the Feels: mBERT improves sentiment analysis in social media. The LLM can accurately classifying the sentiment of social media posts’ text in different languages. This is particularly important in social media monitoring of platforms like Twitter and Facebook which are used by people around the world to express their opinions and feelings.
  • BERT Fakenews Detective: Fakenews can have a big impact. BERT can identify articles based on false information, such as conspiracy theories or rumors. It can also be used to identify articles that are deliberately misleading or Click-bait.
  • mBERT Shopping Assistant: E-commerce sites can improve their search algorithms with BERT. By incorporating natural language understanding and context into the search process.

Reveal and BERT a Match Made in eDiscovery Heaven.

So, what does that mean for me and my legal team?
