Abstract: This article will explain how to build a Chatbot that can handle PDF files step by step.
This article will explain how to build a Chatbot that can handle PDF files step by step. If you prefer a faster deployment method or are interested in how the whole thing works or how it can be achieved, you can refer to the following one-click pull-up solution and complete it in several minutes:
This is how it looks like in a live environment. The chat with the pdf gets the input of the pdf and converts it to text format. Once the PDF document is converted into a text format, LLM or other AI models can analyze the text and extract relevant information. For example, LLM can be trained on a dataset of PDF documents related to a specific topic (such as finance or healthcare) and used to identify key concepts or trends within the text.
We also have an AnalyticDB for PostgreSQL (ADBPG) free trial available.
In order to read the text from the PDF document, LLM needs to tokenize the text first, which involves breaking it down into individual words or phrases. Then, the model processes the tokens and uses them to generate a vector representation of the text, which can be stored in a vectorstore or other data structure.
The vector representation of the text can be used for a variety of tasks (such as classification, clustering, or similarity analysis). For example, ChatGPT could use the vector representation of a PDF document to identify other documents with similar content or classify the document into a specific category based on its content.
Let's use LangChain with adb-pg as vectorstore:
Here are the required cloud components in Alibaba Cloud:
Note: If you have a VPC setup, use it. If not, please create one.
Create Security Group
This will take around 10–15 mins.
