How to use the Tool

Locate the Tool in the template page and click on Use template. You can use the Tool as is or clone it.

Follow these steps to extract data from your PDF documents:

• Upload PDF: Upload the PDF file you want to extract data from.

• Specify Data Points: Customize the data points you want to extract from the PDF. This could include fields such as “Legal name,” “Invoice number,” “Invoice date,” “Bank details,” or “Invoice items breakdown.” Specify the data points that are relevant to your analysis or business needs.

  LLMs are not designed or trained for statistical analysis. Hence, it is recommended to ask for topics or subjects that are clearly mentioned in the text.

• Run the Tool: Once you have uploaded the file and entered your data points, click the “Run Tool” button (on the App page) or use the run options on your data table (bulk/single run) to initiate the the analysis process. The Tool will analyze the PDF document and extract the specified data points. Sit back and relax while the Tool does the work for you.

  Tool execution at Relevance

  Tools and templates can be

  • tested on individually provided inputs:

    • Single run on the App page
    • Single run on the Build page
    • Single run on the data table

  • set to fetch the data from a dataset and apply the analysis on the whole dataset:

    • Bulk run on the data table

• Export and Integrate: Click on “Export” and the extracted data be downloaded to your computer as a CSV file. This CSV contains columns representing the extracted data. You can then integrate the data with other tools or systems for further analysis or processing.

Tool components

If you clone a template, or make a Tool from scratch, you will have access to the Build tab. Build is where one put together different components to build a Tool suitable for their needs.

​

User inputs

1. File to URL: An easy-to-use, one step component, which takes care of all you need when uploading a file for further analysis.

2. Text list input: An input text component suitable for entering a list of items, such as entering a list of topics or examples.

​

Tool steps

There are 5 components under the Tool steps in this analysis flow. These components take care of three tasks: converting PDF to text, the LLM step, and formatting for CSV export.

​

Converting PDF to text

Text to PDF is a Tool step supported by Rlevance AI, which receives a file URL and extract the text from it. This component supports OCR.

​

Large Language Model (LLM)

A large language model component is all set up to provide you access to GPT (and many other LLMs). In the prompt section, you will provide the required information as well as instructions to what is expected to be done.

A Good Prompt

1. Be short and precise with your instruction/request from the LLM
2. Include formatting instruction when necessary
3. Specify the scope using ", """ or similar identifiers

​

Formatting for CSV export

1. Markdown to CSV

   A Javascript code component is available to Run Javascript codes when necessary.

   In this Tool, the code-snippet turns the Markdown format to a CSV.

2. A temporary downloadable file

   Export to a temporary file:

   In many analysis, when the output is generated, it needs to be turned into a downloadable file. At Relevance this can be easily done via a ready-to-use component. This component takes some data that is possible to turn into a CSV format, exports the data to a downloadable CSV and returns a URL to access the file.

3. Export to CSV

   A Javascript code component is available to Run Javascript codes when necessary.

   In this Tool, the second code-snippet simply returns the downloadable URL to the output file.
