This is evident in Named Entity Recognition (NER), which detects and categorizes entities in text. We analyzed 10 NER models on 7 Dungeons and Dragons (D&D) adventure books to assess domainspecific performance. Using open-source Large Language Models, we annotated named entities in these books and evaluated each model’s precision. Our findings indicate that, without modifications, Flair, Trankit, and Spacy outperform others in identifying named entities in the D&D context.  \n1 Introduction  \nNamed Entity Recognition (NER) targets the identification and classification of textual entities, such as names and locations. In the diverse and intricate vocabulary of fantasy literature, like that of Dungeons and Dragons (D&D), NER becomes challenging (Zagal and Deterding, 2018) . D&D, a prominent fantasy literature domain, spans content for its namesake tabletop game (Peiris and de Silva, 2022, 2023 ; Zhou et al., 2022) . These narratives inhabit fictional realms like Forgotten Realms and Dragonlance, bursting with characters, locations, and objects (Gygax and Arneson, 1974) .  \nNER’s utility in fantasy literature is vast: from extracting information and summarizing text to character analysis and plot creation. However, conventional NER models, primarily trained on standard datasets like CoNLL-2003 (Tjong Kim Sang and De Meulder, 2003) or OntoNotes 5.0 (Weischedel et al., 2013), might falter on fantasy texts due to their unique linguistic attributes. Recognizing the need for domain-specific adaptation, other specialized areas such as law (Sugathadasa et al., 2017), medicine (de Silva et al.,  \n2017), and the dynamic landscape of social media (de Silva and Dou, 2021) have already seen research emphasizing it. Large models, as Yao et al. (2021) points out, can face domain adaptation challenges, stressing the need for evaluating NER models specifically on fantasy content.  \nFantasy NER has potential, especially with advancements in image generation. A notable application might involve an image generation model leveraging NER tags to derive prompts and subsequently produce contextually relevant images.  \nOur study contrasts 10 NER models across seven D&D books, each averaging 118,000 words. Manual annotations of entities were made and juxtaposed against model outputs. Through precision assessments and named entity distribution analyses, we glean insights into model performances in the fantasy domain. Our key contributions include:  \n• A pioneering, comprehensive NER model evaluation on fantasy content.  \n• An annotated D&D book dataset for NER studies.  \n• A deep dive into varied NER models’strengths and pitfalls in the fantasy realm.  \n• Discussions on NER’s role and prospects in fantasy literature.  \nFollowing this, Section 2 delves into related NER and fantasy literature works. Section 3 details our data and annotation process, while Section 4 unveils our methods and findings. Sections 5 and 6 respectively discuss insights and conclude our research, and Section 7 outlines potential future endeavors.  \n2 Related Works  \nNER has seen the development of various models like rule-based systems, statistical models, neural  \n1225  \nProceedings of Recent Advances in Natural Language Processing, pages 1225–1233  \nVarna, Sep 4–6, 2023  \n[https://doi.org/10.26615/978-954-452-092-2_130](https://doi.org/10.26615/978-954-452-092-2_130)  \nnetworks, and transformer-based models (Seo et al., 2021 ; Liu et al., 2022 ; Krasnov et al., 2021) .
