Detailed\ninformation about TEM can be found in the following publication\n\n\u003e Liebe L, Baum J, Cech T, Scheibel W, and Dollner J (2024). Detecting and\n\u003e Comparing LLM Capabilities to Human Writers through Linguistic Analysis\n\n## Usage\n\nTo use TEM, first build the model executable and term distance server Docker\ncontainer.\n\n- Build the model:\n  ```sh\n  mkdir build \u0026\u0026 cd build\n  cmake .. \u0026\u0026 make\n  ```\n  An executable will be compiled into `build/topic_evolution_model`.\n- Build the term distance server:\n  ```sh\n  make -C term-distance build\n  ```\n  Note that this may take a while since it downloads word2vec models (total of\n  around 8GB).\n\nOnce this is set up, you can start using TEM.\n\n- Run the term distance server, e.g. with\n  ```sh\n  make -C term-distance run\n  ```\n  This will expose the server on `localhost:8000`. To stop the server, run\n  ```sh\n  make -C term-distance kill\n  ```\n- You can then run the model executable (in `build/topic_evolution_model`)\n  directly or use the provided Python interface in [the `script/`\n  directory](./script), which also features parallelization.\\\n  Note that you need to specify the URL to the term distance server via the\n  environment variable `TEM_WORD_DISTANCE_ENDPOINT`, e.g. if running the\n  executable directly\n  ```sh\n  TEM_WORD_DISTANCE_ENDPOINT=http://localhost:8000/similarity \\\n    build/topic_evolution_model [...]\n  ```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjannis-baum%2Ftopic-evolution-model","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjannis-baum%2Ftopic-evolution-model","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjannis-baum%2Ftopic-evolution-model/lists"}
