Rhetorical figures are like the spice in our communication stew. They help us express ideas more creatively and make our messages stick in people's minds. Think of them as tools that sneak in deeper meanings or emphasize key points. You’ll find these figures in all sorts of places: from dramatic speeches to everyday conversations, and even in not-so-nice stuff like hate speech or fake news.
But here’s the catch: while they play a big role in how we communicate, finding and understanding rhetorical figures is tough, especially for computers. It's kind of like trying to teach a dog to play chess. They might get some moves right, but the finer points are likely to escape them.
Detecting Rhetorical Figures
The Challenge ofDetecting rhetorical figures with computers is all the more tricky because there’s not enough annotated data out there. Imagine trying to teach someone to swim but not having a pool to practice in; that’s the situation researchers face. Currently, there are not enough examples labeled with rhetorical figures, and the few examples that exist are often unbalanced. That means there are way more examples without any figures than with them.
And it’s not just English that struggles. Other languages, like German, have even fewer resources for training computer models. It’s a bit like trying to find a needle in a haystack, where the needle is a rhetorical figure hiding in a sea of plain text.
Creating a Helping Hand: “Find Your Figure” Application
To tackle these problems, a new web application, “Find Your Figure,” was developed. This tool is designed specifically to help users identify and annotate rhetorical figures in German texts. It’s a bit like having a friendly guide that helps you find hidden treasures in a treasure hunt.
The app draws from a special German rhetorical Ontology, called GRhOOT. Think of this ontology as a treasure map that shows where all the rhetorical figures are buried. By using this map, the application helps users navigate through texts and discover different rhetorical figures.
But wait, there's more! The application also has a feature that allows users to interact with a chat-like interface powered by advanced technology called Retrieval Augmented Generation (RAG). This fancy tech helps the application give better answers by pulling in relevant information from the ontology when users ask questions. It’s like having a superhero sidekick that knows everything about rhetorical figures.
Why Are Rhetorical Figures So Hard to Spot?
Rhetorical figures can be very subtle. For example, metaphors might be hiding in plain sight, and sarcasm can be difficult to detect unless you really know the context. It’s similar to deciphering a secret code—one must be familiar with both the code and the key to understand it.
The current methods that computers use to spot these figures often miss the mark. They struggle especially with figures that rely on the structure or sound of words, like alliteration or epiphora. This situation means that while the potential is there, the technology has some catching up to do.
The Role of Data in Detection
One of the first hurdles in detecting rhetorical figures is the lack of data to learn from. Just like how a chef needs a variety of spices to create a great dish, researchers need a diverse set of examples to teach computers about rhetorical figures. Unfortunately, many datasets are skewed, with most examples lacking rhetorical figures altogether.
Researchers are aware of this imbalance and are working to fix it. But it’s a bit of a race against time, especially since many of the existing models focus on English. Other languages, like German, are like a neglected garden with few flowers blooming.
Simplifying the Ontology
The developers of “Find Your Figure” didn’t just stop at creating the app; they also took the time to simplify the GRhOOT ontology. This step was crucial in making the app user-friendly. By breaking down complex relations into simpler terms, they made it easier for users to interact with the ontology.
For instance, instead of overwhelming users with lengthy and complicated definitions, the developers created concise and clear explanations for each figure. They focused on making the experience feel natural, so users wouldn’t need to be linguistic experts to find a rhetorical figure.
A User-Friendly Experience
The application is designed to be as intuitive as possible. Users don’t need a Ph.D. in linguistics to navigate through the app. They can simply enter a sentence, and the app will guide them through the process of identifying the rhetorical figure lurking within it.
The main page of the application is straightforward. Users can submit their text or choose one from a database of previously submitted examples. After entering the details, the app gives users options to select characteristics of the text. It’s like a fun quiz that leads you to your answer.
Interacting with a Language Model
One of the standout features of the application is its ability to engage with users through a chatbot-style interface. Here, users can submit sentences and interact with a language model that pulls from the GRhOOT ontology to assist them. It’s like having a knowledgeable friend right there in your pocket!
This chat feature enhances the experience by making it feel dynamic and engaging. Users can ask anything related to rhetorical figures, and the model works to provide accurate answers based on its knowledge.
Keeping It Safe: Verifying User Input
While the app offers a fun way to learn about rhetorical figures, safety and accuracy are also top priorities. The developers have put measures in place to ensure users don’t inadvertently submit text that belongs to someone else without permission.
When users upload text, they must provide information about the source or author. This step helps protect intellectual property rights and makes users more aware of copyright issues. After all, we want to keep things fair and square, right?
Validating Text Submissions
Another challenge is making sure that the submitted text is valid and meaningful. The team has put several checks in place to ensure that the text isn’t just a jumble of random words. They use language detection tools to verify that the text is in German and even employ grammar checkers.
If a user submits something that doesn’t quite make sense, the app gently alerts them so they can rethink their submission. It’s like a helpful nudge from a friend who says, “Hey, maybe try something else?”
Handling Rhetorical Figure Detection Errors
Detecting rhetorical figures is a tricky business, especially for less common ones. The application currently has a simple rule-based check to identify whether a figure involves perfect lexical repetition, but for the most part, it relies on manual verification.
Once users submit examples, an administrator will check them to ensure that the right rhetorical figure is assigned. It’s a bit of a safety net to make sure everything runs smoothly.
Avoiding Harmful Content
Users might inadvertently submit harmful content, especially when dealing with figures often found in hate speech. While the application allows users to submit all kinds of examples, it excludes harmful ones from being shown to others.
A clever boolean field marks harmful submissions to ensure they aren’t displayed for Annotation. This helps create a safer environment, especially for younger users learning about these figures.
The RAG Integration: Testing for Success
Behind the scenes, the application utilizes the RAG pipeline to enhance its capabilities. By integrating RAG, the app can produce more accurate responses powered by an external knowledge source, in this case, the GRhOOT ontology.
Developers are constantly testing different settings to find the sweet spot for performance. They experiment with various chunk sizes and chunking techniques to make sure the language model can recall information accurately without getting lost in the shuffle.
Evaluating the RAG Pipeline's Effectiveness
To ensure everything is working as planned, the team evaluates how effective the RAG pipeline is. They rely on various metrics to assess performance, focusing on how faithfully the answers align with the information stored in the ontology.
Through these evaluations, they’ve discovered that while advanced techniques don’t always yield better results, the simplicity of basic chunking often shines through. By tweaking different aspects of the app, they work to enhance its overall performance.
The Future of “Find Your Figure”
The web application is just the beginning. The team is excited about what’s to come. They plan to promote the app to potential users and gather feedback to ensure it meets their needs. Future updates could include fun gamification elements to keep users engaged and even more user-friendly features based on real-world experiences.
As more users contribute examples, the app can expand its database, making the tool even more effective. This expansion would not only enrich the ontology but also enhance the performance of the RAG pipeline, making it an even more powerful resource for users.
Ethical Considerations in Development
With great power comes great responsibility. The developers are acutely aware of the ethical implications of their work, especially when it comes to intellectual property rights. They strive to create an app that respects the creators of the original text while still allowing users to learn and explore.
They also recognize that Language Models can sometimes provide incorrect information. The goal is to empower users to assess the truth of what they receive. By offering educational resources within the app and showcasing the retrieved chunks alongside the LLM's responses, users can make informed decisions about the information presented to them.
Conclusion: A Bright Future Ahead
The development of the “Find Your Figure” app marks a significant step forward in improving the detection of rhetorical figures in the digital space. It provides a valuable resource for both researchers and everyday users looking to enhance their understanding of language.
Through interactive features and a commitment to ethical practices, the app creates an engaging platform for learning. As the project continues to grow, it holds the promise of becoming an indispensable tool for anyone curious about the world of rhetorical figures. After all, communication is an art, and this app is here to help paint the picture.

Title: Enhancing Rhetorical Figure Annotation: An Ontology-Based Web Application with RAG Integration
Abstract: Rhetorical figures play an important role in our communication. They are used to convey subtle, implicit meaning, or to emphasize statements. We notice them in hate speech, fake news, and propaganda. By improving the systems for computational detection of rhetorical figures, we can also improve tasks such as hate speech and fake news detection, sentiment analysis, opinion mining, or argument mining. Unfortunately, there is a lack of annotated data, as well as qualified annotators that would help us build large corpora to train machine learning models for the detection of rhetorical figures. The situation is particularly difficult in languages other than English, and for rhetorical figures other than metaphor, sarcasm, and irony. To overcome this issue, we develop a web application called "Find your Figure" that facilitates the identification and annotation of German rhetorical figures. The application is based on the German Rhetorical ontology GRhOOT which we have specially adapted for this purpose. In addition, we improve the user experience with Retrieval Augmented Generation (RAG). In this paper, we present the restructuring of the ontology, the development of the web application, and the built-in RAG pipeline. We also identify the optimal RAG settings for our application. Our approach is one of the first to practically use rhetorical ontologies in combination with RAG and shows promising results.
