Hierarchy of Fields of Study in NLP

A machine readable version of the hierarchy of fields of study in NLP, as developed during our work on NLP-KG, is available in this repository as an OWL file: https://github.com/NLP-Knowledge-Graph/NLP-KG-WebApp/blob/main/NLP-FoS-Hierarchy.owl

This hierarchy is an extension of the NLP Taxonomy (Schopf et al., 2023), which is available in a machine readable format as an OWL file at: https://github.com/sebischair/Exploring-NLP-Research

    abstract = "Scientific literature searches are often exploratory, whereby users are not yet familiar with a particular field or concept but are interested in learning more about it. However, existing systems for scientific literature search are typically tailored to keyword-based lookup searches, limiting the possibilities for exploration. We propose NLP-KG, a feature-rich system designed to support the exploration of research literature in unfamiliar natural language processing (NLP) fields. In addition to a semantic search, NLP-KG allows users to easily find survey papers that provide a quick introduction to a field of interest. Further, a Fields of Study hierarchy graph enables users to familiarize themselves with a field and its related areas. Finally, a chat interface allows users to ask questions about unfamiliar concepts or specific articles in NLP and obtain answers grounded in knowledge retrieved from scientific publications. Our system provides users with comprehensive exploration possibilities, supporting them in investigating the relationships between different fields, understanding unfamiliar concepts in NLP, and finding relevant research literature.
