Homebrewed Software: A Handwriting Transcription App

By Shawn Graham Continuing from the last experiment and ruminating on Drew Breunig's taxonomy of use cases for AI (in short: gods, interns, cogs, and toys) as well as 'homecooked software' I undertook to use Anthrophic's 'Claude' model to see what I could do. I'm building a cog via Claude's 'artifacts' feature which allows... More

Transcribing Handwriting with a Multimodal Model

by Shawn Graham Legacy archaeological data is often trapped in handwritten context sheets, site diaries, and scraps of paper. Transcribing such materials so that one can work with them is time consuming and difficult. If you're an English speaker, trained in North American cursive you're probably better off that the average undergrad today who... More

Using a Large Language Model and Pydantic to Extract Structured Data for Cultural Heritage Crime

A few weeks ago Vianney Mixtur published a blog post and related code repository showing how he used the Mixtral model to pull together recipe data from semi-structured cookery information. We have been experimenting here for some time using a variety of approaches to create knowledge graphs from academic articles, newspaper articles, auction... More

The Behaviour Space(s) of Large Language Models

By Shawn Graham. For many years, I built agent based models of various phenomena based on archaeological data. These are models of interacting software agents in a simulated environment, with many different parameters; the first step in understanding what your model implies for the culture under study is to understand how your model behaves....

Qualitative Analysis of Social Media Posts – A Workflow from OCR to Obsidian

In the past, we have applied many different distant reading techniques to social media posts related to the human remains trade. As part of a new analysis, we are exploring a computer-facilitated close reading of social media posts. Here we detail a workflow that assumes one already has a collection of images that capture...

Trawling Data: The Panama Papers and our Knowledge Graph

The dataset for the Panama Papers is available here. Wouldn't it be great to examine it for people connected to the antiquities trade? In this post I try to do that, using our knowledge graph generated from the Trafficking Culture Encyclopedia. Behind that link you will find: Offshore Leaks (2013) Panama Papers (2016) Bahamas...

Further Adventures with LLM-GPT4All and Templates

Yesterday Simon Willison updated the LLM-GPT4All plugin which has permitted me to download several large language models to explore how they work and how we could work with the LLM package to use templates to guide our knowledge graph extraction. For instance, using GPT4, we could pipe a text file with information in it... More

Using Simon Willison’s LLM Package to Extract a Knowledge Graph

Simon Willison's LLM package is a lovely little command line utility that allows you to work with many different large language models. In this post, we use LLM to extract a knowledge graph from a mermaid diagram sketch. 1. Sketch out the basics of your knowledge graph. On paper - yes, on paper! It's... More

archaeCLIP: or building a visual search engine for archaeology

If you take a bunch of text, and drop it through a large language model, you can get what is called an 'embedding' - a mathematical representation of where that text, that idea you wrote, is located within what the model 'knows'. Other texts that get embedded get a location, too, and once you... More

Mermaid Diagram to Ontology via GPT3 for the illicit antiquities trade

I believe chatgpt using GPT4 is only available to plus customers (July 2023 version) so what follows was developed using GPT3, though in my next experiment, I will be able to use GPT4 to process unstructured text in bulk using the results of today's experiment. In a blog post, Kingsley Uyi Idehen demonstrated his... More
