🤖AI-Powered Contract Queries: Use Language Models for Effective Analysis!🔥

Imagine you were given a large contract and asked a really specific question about it: "What is the notice for termination for convenience?" It would be an ordeal to locate the answer for this in the contract.

But what if we could use AI 🤖 to analyze the contract and answer this for us?

What we want here is to perform something known as retrieval-augmented generation (RAG). This is the process by which we give a language model some external sources (such as a contract). The external sources are intended to enhance the model's context, giving it a more comprehensive understanding of a topic. The model should then give us more accurate responses to the questions we ask it on the topic.

Now, a general purpose model like Chat-GPT might be able to answer questions about contracts with RAG, but what if we instead used a model that's been trained and fine-tuned specifically on contract data?


Our AI model 🤖

For this example, we'll be using LLMWare's dragon-yi-6b-gguf model. This model is RAG-finetuned for fact-based question-answering on complex business and legal documents.

This means that it is specialized in giving us short and concise responses to questions involving documents like contracts. This makes it perfect for our example!

This is also a GGUF quantized model, meaning that it is a smaller and faster version of the original 6 billion parameter dragon-yi-6b model. Fortunately for us, this means that we can run it on a CPU 💻 without the need for powerful computational resources like GPUs!

Now, let's look at an example of using the llmware library for contract analysis from start to end!


Step 1: Loading in files 📁

Let's start off by loading in our contracts to be analyzed. The llmware library provides sample contracts via the Setup class, but you can also use your own files in this example by replacing the agreements_path below.



local_path = Setup().load_sample_files()
agreements_path = os.path.join(local_path, "AgreementsLarge")


Enter fullscreen mode Exit fullscreen mode

Here, we load in the AgreementsLarge set of files.

Next, we'll create a Library object and add our sample files to this library. An llmware library breaks documents down into text chunks and stores them in a database so that we can access them easily later.



msa_lib = Library().create_new_library("msa_lib503_635")
msa_lib.add_files(agreements_path)


Enter fullscreen mode Exit fullscreen mode

Step 2: Locating MSA files 🔍

Let's say that we want to consider only MSA (master services agreements) files from our sample contracts.

We can first create a Query object containing all our files, and then run a text_search_by_page() to filter only the files that contain "master services agreement" on their front page.



q = Query(msa_lib)
query = "master services agreement"
results = q.text_search_by_page(query, page_num=1, results_only=False)
msa_docs = results["file_source"]


Enter fullscreen mode Exit fullscreen mode

The results from the text search will be a dictionary containing detailed information about the text query. However, we're only interested in the file_source key representing the file names.

Great! We now have our MSA files.

Step 3: Loading our model 🪫🔋

Now, we can load in our model using the Prompt class in the llmware library.



model_name = "llmware/dragon-yi-6b-gguf"
prompter = Prompt().load_model(model_name)


Enter fullscreen mode Exit fullscreen mode

Step 4: Analyzing our files using AI 🧠💡

Let's now iterate over our MSA files, and for each file, we'll:

  • identify the text chunks containing the word "termination",
  • add those chunks as a source for our AI call, and
  • run the AI call "What is the notice for termination for convenience?"

We can start by performing a text query for the word "termination".



for i, docs in enumerate(msa_docs):
    doc_filter = {"file_source": [docs]}
    termination_provisions = q.text_query_with_document_filter("termination", doc_filter)


Enter fullscreen mode Exit fullscreen mode

We'll then add these termination_provisions as a source to our model.



sources = prompter.add_source_query_results(termination_provisions)


Enter fullscreen mode Exit fullscreen mode

And with that done, we can call the LLM and ask it our question.



response = prompter.prompt_with_source("What is the notice for termination for convenience?")


Enter fullscreen mode Exit fullscreen mode

Results! ✅

Let's print out our response and see what the output looks like.



for i, resp in enumerate(response):
    print("update: llm response - ", resp)


Enter fullscreen mode Exit fullscreen mode

Here's what the output of our code looks like:

Sample output

What we have is a Python dictionary with several keys, notably:

  • llm_response: giving us the answer to our question, which here is "30 days written notice"
  • evidence: giving us the text where the model found the answer to the question

The dictionary also contains detailed information about the metadata of the AI call, but these are not relevant to our example and have been omitted from the output above.


Human in the loop! 👤

We're not done just yet! If we wanted to generate a CSV report for a human to review the results of our analysis, we can make use of the HumanInTheLoop class. All we need to do is save the current state of our prompter and call the export_current_interaction_to_csv() function.



prompter.save_state()
csv_output = HumanInTheLoop(prompter).export_current_interaction_to_csv()


Enter fullscreen mode Exit fullscreen mode

Conclusion

And that brings us to the end of our example! To summarize, we used the llmware library to:

  1. Load in sample files
  2. Filter only the MSA files
  3. Use the dragon-yi-6b-gguf model to ask questions about termination provisions.

And remember that we did all of this on just a CPU! 💻
