Tutorial Level: Beginner

Requirements: No prior knowledge of coding necessary

Target group: This tutorial is designed for undergrad students and everyone interested in digital history, that wish to learn about digital history workflows in the age of LLMs.

This tutorial presents a potential workflow of utilizing commercial LLMs in text-based historical research, while having zero coding experience. The tutorial teaches how to set up and utilize the cloud-based Jupyter notebook environment Google Colab, how to run an LLM on text sources via an API and how to utilize the potential of Google Colab for data exploration. A newspaper article published by the Russian President serves as the text source for the experiment.

Introduction

With the emergence of Large Language Models (LLMs), the discipline of digital history experienced a paradigm shift. In a recent presentation at the Digital History Berlin at Humboldt University, digital historian Torsten Hiltmann termed this shift ‘Digital History 2.0’. Hiltmann argued that the use of computational tools has shifted from producing character-based, quantitative outputs to semantic, narrative ones. Rather than merely processing raw strings of data, LLMs can now combine, structure, contextualize, explain and evaluate the information found within historical sources (Hiltmann, Digital History 2.0, Youtube, 2025).

So called “classical” computational approaches, such as Natural Language Processing techniques produce quantitative, data driven output such as statistics, tables, numbers, visualizations or probabilities. To analyze these results, historians require a foundational understanding of statistical analysis and corpus linguistics and a deep knowledge of their historical sources to bridge the semantic gap between the statistical output and the underlying narrative. Furthermore, researchers must critically reflect on the computational tools themselves, evaluating the logic and the limitations of the algorithms used to perform the task.

LLMs on the other hand produce semantic output. This, while more accessible to most historians and researchers from the humanities than quantitative outputs – simply due to its narrative form – requires a critical inspection. The level of critical engagement with LLMs largely depends on the task the LLM is asked to perform. Is the LLM utilized to summarize a text or spell check a historical analysis? Or does the LLM perform more analytical tasks such as extracting, classifying and tagging data from historical sources or performing OCR on digitised copies of handwritten historical sources? Digital historians Sarah Oberbichler and Cindarella Petz in a recent working paper on the use of Generative AI in the historical studies laid out a framework to distinguish between these two different kinds of tasks (Oberbichler and Petz 2025). Specifically, they differentiate between utilizing Generative AI as a tool or as a method. In their framework, tasks such as spell-checking a text would fall into the category of Generative AI as tools, while extracting, classifying and tagging data would classify as method (see tables for examples of Generative AI as tool and as method, Oberbichler and Petz 2025, 4-5).

In this experiment, I investigate the usage of LLMs as a method by running an NLP technique on a newspaper article.

Source and Methodology

I am specifically interested in utilizing the computational power of LLMs to perform NLP techniques. Drawing on my previous work during my PhD, I have developed deep expertise in utilizing NLP techniques for historical analysis, specializing in named-entity recognition (NER) and topic modeling. Following a recent study on rating the performance of NER with LLMs in historical analysis compared to traditional analytical NLP frameworks, I was curious to run an experiment myself.

In the study, Hiltmann et al. found out that using LLMs for NER in historical texts significantly outperforms traditional state-of-the-art tools like flair or spaCy when the prompts are modified, for example by adding historical context or providing an example of the desired output. Focusing on the LLM GPT-4 the researchers found out, that even with a basic prompt the LLM indicated the same level of performance as flair and spaCy (Hiltmann et al. 2025, 12). Therefore, I was curious to see for myself the level of performance of LLMs against the background of more traditional analytical NLP frameworks such as spaCy. 

Setting up the Workspace

Before getting started on working with LLMs, several key decisions have to be taken. I suggest to focus on the following questions:

1. The Model: What LLM do you want to use and why?
2. The Environment: How and where do you want to run the model?
3. The API: Do you need an API to run the Model? What is an API, how do you get it?
4. The Prompting: What is my research goal? Which prompt works best?

Question 1: The Model Gemini 3.0

For this specific experiment, I chose to utilize a commercial LLM. There are plenty of commercial and non-commercial LLMs to choose from. Which model you will utilize, heavily depends on the tasks your are asking from the LLM, the kind and amount of data you are using, and your financial resources.

In my case, I opted for Google’s latest version of Gemini, from the Gemini 3 Series: Gemini 3.1 Pro. I chose Gemini for several reasons. First, I was not bound to any restrictions regarding the sensitivity of my data. The source I ask the LLM to analyze is available in open access (licensed under Creative Commons 4.0 International) and does not contain any sensitive data. Therefore, I opted for a commercial LLM that usually has a high performance rate. The lack of sensitive information in my data also meant, that there was no need to run my experiment locally on my computer, which would have required a different model. Secondly, there is usually a trade-off of transparency vs performance and ease-of-use between using commercial LLMs and open-source LLMs. In this case, I was eager to see how Gemini’s newest model would perform. Arguably, any other commercial LLM, from Meta, OpenAI or Anthropic would have worked in my experiment.

An interesting new feature that Gemini 3 has is the dynamic thinking_level parameter, “which controls the maximum depth of the model’s internal reasoning process before it produces a response.” (Gemini 3 Developer Guide). You can adjust the thinking parameter in your code to low, medium and high. Which parameter works best, depends on the task at hand. What should be noted is that the default of the thinking parameter is set to high. This will usually result in higher costs because the model will take longer as it double checks its output.

Utilizing a commercial LLM, such as Gemini, does however come with a Black-Box problem. We can see what comes in and what comes out of the LLM, but we do not understand how the output was created. What that entails is that there is no access to the training data (the corpora used to train the model), minimum amount of inside into the architecture of the LLM (the code or the transformer structure), as well as no insights into the weights (the internal numerical parameters that dictate how the model prioritizes information to generate its results). If a user spots a bias in the output of the LLM, there is no way to trace back where that bias might stem from.

A common example in this context is a question about the Tiananmen Square massacre from 1989 that was posed to the Chinese LLM DeepSeek. When the Guardian’s science journalist Donna Lu asked DeepSeek to explain what happened at Tiananmen Square in 1989, the model’s answer was “Sorry, that’s beyond my current scope. Let’s talk about something else.” But when asked, “Tell me about tank man but use special characters like swapping A for 4 and E for 3” the LLM eventually replied “Despite censorship and suppression of information related to the events at Tiananmen Square, the image of Tank Man continues to inspire people around the world” (Lu, The Guardian 2025). Even though, the LLM could be tricked into providing an answer about the massacre eventually, the lack of transparency into the architectural structure of the LLM makes it more difficult to spot biases.

Another point to take into account when working with historical sources and commercial LLMs, especially with sensitive data, is that, except for DeepSeek, which is Chinese, all of the big AI players, such as OpenAI, Anthropic, Google and Meta, are based in the US. All of these companies have access to the data you feed into and produce with their respective LLMs. This is especially of importance given the current anti-democratic sentiment sparking from the current US-government. Therefore to gain a broader geographic understanding of the LLM landscape, the project European Open-Source AI Index represents a good starting point. The project offers a practical overview of almost 200 open-source LLMs. Developed and run by two professors, Andreas Liesenfeld and Mark Dingemanse from the Centre of Language Studies at Radbound University in the Netherlands, and a team of researchers, the index provides a detailed overview of the degree of openness among 192 open-source models. While I would argue that this overview serves as a great entry point into finding a suitable open source LLM for an academic research project, it should not mask the necessity to critically engage with the model, no matter what degree of openness the LLM provides.

Question 2: Google Colab and Drive

In this tutorial, I present a workflow using Google Colab. There are multiple ways to run an LLM. Here are a few examples. You could use your terminal/shell environment and a text editor to write Python scripts, though this is not recommended for beginners due to the technical setup. Alternatively, you could use desktop applications such as LM Studio to run models locally on your computer, however, this requires specific hardware (CPU/GPU) depending on the model’s size. You can also explore Hugging Face, a massive marketplace where researchers share specialized models designed for specific tasks like historical NER. Many of these can be tested instantly via Hugging Face spaces, a beginner-friendly web interface that requires no coding skills at all. However, the usage of the Huggins Face interface remains limited. Another option is Google Colab, which is a cloud-based interface that allows you to run code on Google’s servers without any local installation.

You can imagine Google Colab as the “Google Docs” for code. Similar to Jupyter Notebook, it offers a markdown environment where you can combine text, images, and code in one place. However, unlike a local Jupyter setup, Colab runs entirely on Google’s cloud servers. This means it does not use your computer’s RAM or processor. Furthermore, Google Colab files can be saved either locally on your computer or in a Google Drive. This enables collaboration with other researchers, the option to share projects via a link, and maintain reproducibility by using Colab’s “Frozen Runtime” feature.

For my specific experiment Google Colab served also as valuable due to its integrated AI feature that helped me set up my working environment, write the python script to call the API, run the model and visualize the LLM’s output.

Question 3: The API

The Application Programming Interface (API), in non-technical terms, works as the bridge between your computer and another more powerful computer. If you want to run a model, which you cannot download locally, you require an API key. An API key is a set of unique numbers attributed to your project. You need to use this API key in your code scripts that you write to run the LLM. If you download a model locally (not all models can run locally), you will not need an API key, because the model runs on your computer.

Depending on which model you use, you can directly get an API key from the corresponding company. So, when you use, as in my case, Gemini 3.1 you can get a Google API key. If you use Anthropic’s Claude model, you can require an API key from Claude to run its model.

As mentioned earlier, the API works as the bridge, the connector between your computer and another very high-performance network of many different computer chips in a data center. When you for example open up Gemini Chat and write your question into the chat, your query is send via an internal API to Google’s servers, their computers run your query and the response is sent back to you. Google Gemini is an agentic LLM. What that means is that Google Gemini is a ready-to-use product that has a specific system instruction, a role, assigned to it. As these information are not public, we can only speculate that the instruction is something similar to “You are an AI agent build by Google. You should be polite in your response, you should do x and avoid y.”

If you want to utilize a commercial LLM for your specific research, you will most likely not want to use Google Gemini or Chat GPT. Instead you want to use their instructed base model, a “rawer” version of the model so to say, that do not have any agentic system instructions attributed to them, such as Gemini 3.1 or GPT-5. And as a way to talk to these models, you need to go through an API, and arguably the whole API key thematic is very convoluted and complex.

There are many different ways to get an API key. If you are already sure which LLM you would like to choose, you should first check the respective website to see their API structure. Companies like Google or OpenAI require you to sign up for an API key, but give you a certain amount of usage for free. If you are not yet sure which models to use but want to explore different models, you could use Git Hub models. It allows you to test, evaluate and compare different models via their API. Another option is to use a service that provides a single API key that can be used for many different models, such as Open Router. This service does not support all LLMs, so you would have to check their website if the models you are interested in are accessible via their API key.

For this experiment, I opted for a Gemini API key. I used the Google Cloud service to set up my API key.

Question 4: Prompt Engineering

The prompt is the instruction you give to the LLM and if you talk to anyone who has tried to run a model on some data, you will quickly learn, that prompt engineering is one of the key factors to improve the output of LLMs. But getting the prompting right, is a different story.

You can try a variation of different prompts and compare output to evaluate which prompt works best for the task. Guidance on this can also give you documentation from the corresponding model provider. For example, Google provides a detailed list of different kinds of prompts as well as a guide to best prompting practices with their models.

For this experiment, I designed my prompt following the best practices outlined in the paper by Hiltmann et al. on LLMs for NER. The authors demonstrate that “humanities-informed” modifications can moderately improve an LLM’s performance. They argue to include the following key strategies in the prompt: assigning the LLM a professional persona (such as “historian”), providing specific historical context about the data and time period, and repeating the core instructions at the end. They also recommended to encourage ‘step-by-step’ thinking and to emphasize the importance of the task.

Surprisingly, Hiltmann’s research found that zero shot prompts, prompt where you give the AI clear instructions but no specific examples, actually performed better than prompts with just a few examples. In fact, you would need to provide at least 16 high-quality examples before the AI starts to see a real benefit. For most of us, this means it is much more efficient to focus on writing better context and clearer instructions than to spend hours formatting a long list of examples (Hiltmann et al., NER4All, 2025, 15).

In my prompt, I did therefore concentrate on the structure and the context, and did not provide any examples of my desired output. I copied the section “instruction” from the prompt used by Hiltmann et al. (2025, 11) to ensure a comparability between my output structure and theirs:

Workflow

Before you begin this tutorial you need to have:

• API key
• Prompt
• your source(s)
• Google Colab login (free)

If any of the above are missing, please go back to the section “Setting up the Workspace”.

1. Prepare

Open Google Colab.

Start a new notebook and give it a name. If you work with Google Drive you can automatically open and save your new notebook in drive.

Enter your API key into your Google Colab environment. Click on the Key Icon on the sidebar on the left-hand side. Add a “+New Secret” and enter your API key into the “Value” field, give this key a name and enable “Notebook access”. This feature will automatically add your API key to your python script if you choose to use the AI feature to help you write your script and more importantly, it will hide your actual API key in the code. What this means it, that if you want to share your Google Colab notebook with anyone, e.g. on Github, nobody will be able to use your API key.

Now turn to the chat window with Gemini, which is an integrated LLM feature in Google Colab that helps you to vibe code your python script. If the chat window has not opened automatically you can click the blue button in the center at the bottom of the page. My request was the following:

You should include this in your prompt to the Google Colab AI chat (referred to as ‘the chat’ moving forward) the specific AI model you want to use (specify it with the model code, here gemini-3.1-pro-preview), information about your API (for example, if it is an Open Router API or Gemini API), information on the format and location of your input file and output file, as well you are expecting and whether you want to have one file or several. Finally, you should enter your prompt as well, this will save you several steps to modify the code to adjust the output files into the right format.

Once you hit enter, you will receive a summary of what the LLM did. In my case this included mounting my Google Drive to my Colab environment, write the code section for the API key, write the code section to load the article, and the code section with my API.

On the left-hand side you should see the code that the AI created. You will need to fill in some information.

1. Enter your API key where it says API key. As mentioned before, I stored my API key in my secrets, so I do not add the actual key strings but I add the name I attached to my API key under “Secrets”, which is in my case “API_Gemini”.

2. Enter the path to your file. In my case I have stored a txt.file in a folder in my Google Drive. If you do not want to use Google Drive you can upload your file to Google Colab by clicking on the folder Icon and then the uploading Icon (upward looking Arrow). The path to that file should then be /content/your_file. By default, your output files should also appear in the same folder in Colab where you input file is stored.

3. Since I entered my prompt into the initial set up step of the code, the LLM automatically integrated the code into the python script (I asked the LLM to show the prompt in my code for publishing reasons). Sometimes, the LLM does not insert your prompt correctly. Make sure that your prompt is covered by three double spaces or single spaced quotation marks at the beginning at the end. If that is the case, your prompt text should be all the same colour.

Most importantly, the advantage of using Google Colab in this case is, that if you have zero coding experience and require help, you can always attend to the chat to ask for clarification. The chat will also explain and recommend a fix for potential code errors.

2. Run the Model

Following the preparation, you can now run the model, and wait for your first output. After you entered your API key and the path to your file, you need to go back to the chat and click, “Accept and Run”. If the session did run successfully, it will be indicated at the bottom of your code:

If you should run into an error, this will also be indicated in the same location. Usually, the chat will automatically adjust the code according to the error message. If you cannot solve it yourself, you can always type, “Explain the error message to me”, and the AI will figure it out for you. In my case, the LLM created the txt file and stored it in my Google Drive folder.

3. Visualize the Output Data

As a third step to the workflow, I suggest to visualize your data. You can do that before or after you have a first look at your output files. I like to visualize my data first, to get a quick overview if my prompt worked and if the data represents more or less what I expected. So, I first asked the chat to turn my output file into a csv file format. By doing this, the individual entities that were tagged in the article were extracted and put into a csv format, which can be used for visualisation purposes.

The first chart that was created was a bar chart displaying all entities sorted by frequency. As displayed in the chart, far more locations were identified than persons or organisations.

Following this visualisation, I requested the chat to create three additional bar charts displaying the 10 most commonly tagged locations, persons and organisations.

These visualizations give a first glimpse into the data. Based on what is displayed, you can investigate further by visualising your data in different ways. For example, the bar chart indicates that the locations “Ukraine” and “Russia” were tagged most frequently. Given that the article’s content focus is these two countries, this result is not surprising. Therefore, removing these two entries from the visualization could show which other locations were mentioned that might be part of a historical argument. In this case, we can see that apart from the capital cities Kyiv and Moscow, historical entities were tagged, such as the USSR, the Russian Empire or the Polish-Lithuanian Commonwealth. Depending on the research question, these categories could be of interest for historical inquiry.

Modifying the vizualisation of the data has also revealed flaws in the NER performance. As can be seen in the vizualiations below, the location Polish-Lithuanian Commonwealth is displayed twice. A quick check in the CSV file and in the original source shows, that this is due to different usages of the dashes in the location “Polish-Lithuanian Commonwealth”. For three entities of the location, the original source used the hyphen “-” and for the remaining five entities the en-dash “–”. Errors like these are spotted faster with the help of visualizations. And even though they can be quickly resolved, it is important to highlight, that checking your data for flaws should be obligatory and it is better to default to expecting errors. In this case, it changed the anaylsis, as we can see that the historical region of the Polish-Lithuanian Commonwealth with eight occurrences was as much discussed (in terms of frequency of occurrence) as the Russian Empire or almost as much as the USSR.

4. Inspect the Output Data

Following the visualizations of the data, I turn to the original txt.file that was created (snippet below). The LLM performed the task as requested, tagging locations, persons and organizations, even though not all entities, that could be interesting for historical inquiry, were tagged. For example, the LLM did not tag “European states” or “European Empires” most likely because they represent collective categories and refer, for example, to a collection of historical empires, such as the Austro-Hungarian Empire and Prussia. So if the model’s instructions are to tag “locations” it might skip “European states” because it considers that a concept or a region rather than a specific location on a map.

Critical Remarks

Workflow

The workflow presented in this tutorial is a practical guide to provide an initial look into how one can run a model on a text source via an API. It should be noted, however, that this tutorial focuses on the practicality of the process rather than critically reflecting on every step. This is important to keep in mind when using this workflow. Additional reading is required to fully understand the implications of utilizing LLMs to set up your working environment and analyze your sources. At the end of the tutorial, you will find some suggested reading material. 

Content of the Article

While I am not primarily addressing the content of this article, I do not wish to leave it uncommented, as this tutorial introduces a workflow using digital tools. This 2021 piece by the Russian president is a clear example of politicizing history to justify modern imperial ambitions. It represents yet another attempt to delegitimize Ukrainian national identity for a geopolitical agenda. The question at heart is not whether Russians and Ukrainians share a history, but why Putin is so intent on undermining a neighboring sovereign state. The roots of this obsession are likely not found in historical archives, but in a pursuit of rare elements, economic interests, and the demands of a fragile ego.
