Introducing Text Analysis with Large Language Models

In this blog post, we will explore how to leverage large language models for advanced text analysis. Specifically, we will walk through a demonstration of ingesting a text file, constructing an analysis prompt, calling a language model API, and formatting the results into an easy to understand summary.

Large language models such as GPT-3 and Claude have opened up new possibilities for automating complex text analysis tasks. By providing these models with a well-constructed prompt, they can produce detailed summaries, identify key themes and takeaways, and even emulate the writing style of subject matter experts.

Overview of the Video Demo

We will be using an example news article text from ABC news as our input data. The text discusses predictions and viewpoints from OpenAI CEO Sam Altman regarding the potential risks and benefits of artificial intelligence. Our overall goal will be to have the language model read and analyze this text, acting as an award-winning journalist to write up an informative summary.

Understanding the Analysis Process

At a high level, our automated text analysis process will involve:

• Ingesting the raw text file
• Constructing a detailed prompt to instruct the language model
• Calling the Claude API to generate a text completion
• Formatting the results for easy human consumption

Implementing the Text Analysis Workflow

With the overview and goals covered, let's walk through how to actually implement this automated text analysis demonstration step-by-step.

We will configure credentials, ingest the file, construct a prompt for analysis, call the API, and format the results.

Configuring API Credentials

The first implementation step is to sign up and configure API credentials for accessing the Claude API. This provides secure authentication for us to call Claude within our code. Once credentials are configured, we import the necessary libraries for working with Claude and reading text files.

Ingesting the Text File

Next, we load the raw text from our ABC News example file and store it in a string variable. This contains the full data that we want Claude to analyze.

Constructing the Analysis Prompt

A key step is carefully constructing the prompt that instructs Claude what type of analysis we want on the text. Our prompt tells Claude to act as an award-winning journalist and write a two paragraph analysis regarding key themes and takeaways from the article text. We format the prompt as a function where the text variable gets injected in the middle, separating the setup and instructions from the actual content to analyze.

Calling the API for Text Analysis

With credentials configured and prompt constructed, we can now call the Claude API which executes our prompt by analyzing the text and generating a completion. We assign this output to a variable to use in the next formatting step.

Formatting the Results

While readable, the raw Claude output has some extra metadata. We create a function to format the results and improve human readability. When called, this formats the summary analysis into easy to digest paragraphs.

Reviewing the Text Analysis Results

With the automated workflow steps covered, let's review the actual text analysis results produced by Claude acting as our journalist.

It has generated a two paragraph summary relating to the overall optimistic yet cautious theme regarding AI progress.

Summarizing the Overall Tone

The first paragraph captures the overall positive yet realistic tone from OpenAI CEO Sam Altman regarding AI having great potential while acknowledging more work is needed on safety.

Highlighting Key Takeaways

The second paragraph draws out Altman's view that AI systems like GPT-3 are impressive yet still require human guidance rather than fully independent operation at this stage.

Conclusion and Next Steps

In closing, this demonstration showed how large language models can be leveraged for automated text analysis - including ingestion, prompts, API calls, and formatting.

Some next steps to build on this foundation could be expanding the summary length, comparing sentiment across multiple articles, or building an interactive web interface for text analytics.

FAQ
