-    # OpenAlex Mapper
-    
-    OpenAlex Mapper is a way of projecting search queries from the amazing OpenAlex database on a background map of randomly sampled papers from OpenAlex, which allows you to easily investigate interdisciplinary connections. OpenAlex Mapper was developed by [Maximilian Noichl](https://maxnoichl.eu) and [Andrea Loettgers](https://unige.academia.edu/AndreaLoettgers) at the [Possible Life project](http://www.possiblelife.eu/).
-
-    To use OpenAlex Mapper, first head over to [OpenAlex](https://openalex.org/) and search for something that interests you. For example, you could search for all the papers that make use of the [Kuramoto model](https://openalex.org/works?page=1&filter=default.search%3A%22Kuramoto%20Model%22), for all the papers that were published by researchers at [Utrecht University in 2019](https://openalex.org/works?page=1&filter=authorships.institutions.lineage%3Ai193662353,publication_year%3A2019), or for all the papers that cite Wittgenstein's [Philosophical Investigations](https://openalex.org/works?page=1&filter=cites%3Aw4251395411). Then you copy the URL to that search query into the OpenAlex search URL box below and click "Run Query." It will download all of these records from OpenAlex and embed them on our interactive map. As the embedding step is a little expensive, computationally, it's often a good idea to play around with smaller samples, before running a larger analysis. After a little time, that map will appear and be available for you to interact with and download. You can find more explanations in the FAQs below.

-    ## Who made this?
-
-    This project was developed by [Maximilian Noichl](https://maxnoichl.eu) (Utrecht University), in cooperation with Andrea Loettger and Tarja Knuuttila at the [Possible Life project](http://www.possiblelife.eu/), at the University of Vienna. If this project is useful in any way for your research, we would appreciate citation of **...**
-
-    This project received funding from the European Research Council under the European Union's Horizon 2020 research and innovation programme (LIFEMODE project, grant agreement No. 818772).
-
-    ## How does it work?
-
-    The base map for this project is developed by randomly downloading 250,000 articles from OpenAlex, then embedding their abstracts using our [fine-tuned](https://huggingface.co/m7n/discipline-tuned_specter_2_024) version of the [specter-2](https://huggingface.co/allenai/specter2_aug2023refresh_base) language model, running these embeddings through [UMAP](https://umap-learn.readthedocs.io/en/latest/) to give us a two-dimensional representation, and displaying that in an interactive window using [datamapplot](https://datamapplot.readthedocs.io/en/latest/index.html). After the data for your query is downloaded from OpenAlex, it then undergoes the exact same process, but the pre-trained UMAP model from earlier is used to project your new data points onto this original map, showing where they would show up if they were included in the original sample. For more details, you can take a look at the method section of this paper: **...**
-    
-    ## I want to add multiple queries at once!
-
-    That can be a good idea, e. g. if your interested in a specific paper, as well as all the papers that cite it. Just add the queries to the query box and separate them with a ";" without any spaces in between!
-
-    ## I think I found a mistake in  the map.
+# Create and configure static directory
+static_dir = Path("./static")
+static_dir.mkdir(parents=True, exist_ok=True)
 
-    There are various considerations to take into account when working with this map:
+# Mount static directory to FastAPI
+app.mount("/static", StaticFiles(directory="static"), name="static")
 
-    1. The language model we use is fine-tuned to separate disciplines from each other, but of course, disciplines are weird, partially subjective social categories, so what the model has learned might not always correspond perfectly to what you would expect to see.
+# Tell Gradio which paths are allowed to be served
+os.environ["GRADIO_ALLOWED_PATHS"] = str(static_dir.resolve())
 
-    2. When pressing down a really high-dimensional space into a low-dimensional one, there will be trade-offs. For example, we see this big ring structure of the sciences on the map, but in the middle of the map there is a overly stretchedstring of bioinformaticsthat stretches from computer science at the bottom up to the life sciences clusters at the top. This is one of the areas where the UMAP algorithm had trouble pressing our high-dimensional dataset into a low-dimensional space. For more information on how to read a UMAP plot, I recommend looking into ["Understanding UMAP"](https://pair-code.github.io/understanding-umap/) by Andy Coenen & Adam Pearce.
+def process_and_save(text):
+    """Simple function that saves text to a file and returns file path"""
+    # Save text to a file in static directory
+    file_path = static_dir / "output.txt"
+    with open(file_path, "w") as f:
+        f.write(text)
     
-    3. Finally, the labels we're using for the regions of this plot are created from OpenAlex's own labels of sub-disciplines. They give a rough indication of the papers that could be expected in this broad area of the map, but they are not necessarily the perfect label for the articles that are precisely below them. They are just located at the median point of a usually much larger, much broader, and fuzzier category, so they should always be taken with quite a big grain of salt.
