DEBRA: On the Unsupervised Learning of concept Hierarchies from (Literary) Text

International Journal of Intelligence Science 2023年第4期13卷 81-130页

作者： Peter J. Worth Domagoj Doresic Department of Electrical Engineering and Computer Science Florida Atlantic University Boca Raton USA Interdisciplinary Research Unit Mathematics and Life Sciences University of Bonn Bonn Germany

With this work, we introduce a novel method for the unsupervised learning of conceptual hierarchies, or concept maps as they are sometimes called, which is aimed specifically for use with literary texts, as such distinguishing itself from the majority of research literature on the topic which is primarily focused on building ontologies from a vast array of different types of data sources, both structured and unstructured, to support various forms of AI, in particular, the Semantic Web as envisioned by Tim Berners-Lee. We first elaborate on mutually informing disciplines of philosophy and computer science, or more specifically the relationship between metaphysics, epistemology, ontology, computing and AI, followed by a technically in-depth discussion of DEBRA, our dependency tree based concept hierarchy constructor, which as its name alludes to, constructs a conceptual map in the form of a directed graph which illustrates the concepts, their respective relations, and the implied ontological structure of the concepts as encoded in the text, decoded with standard Python NLP libraries such as spaCy and NLTK. With this work we hope to both augment the Knowledge Representation literature with opportunities for intellectual advancement in AI with more intuitive, less analytical, and well-known forms of knowledge representation from the cognitive science community, as well as open up new areas of research between Computer Science and the Humanities with respect to the application of the latest in NLP tools and techniques upon literature of cultural significance, shedding light on existing methods of computation with respect to documents in semantic space that effectively allows for, at the very least, the comparison and evolution of texts through time, using vector space math.

Pressing demand for innovation in CAI/L systems calls for up-scale methods with governances capable of escalating learning and managing knowledge from learning. Combinatorial effort of CAI/CAL with work-integrated-dissertation-environment,ideas compression techniques and Socrates delivery methods not only produces learning but brings esteem into knowledge retention. The concept of a BOM capacitated CRM facilitates synchronization of learning materials,and continuous benchmarking with work environment. CAI/CAL system for training international project managers serves to initiate innovation in narrowing gap for producing international project manager for mutual benefits between China and countries that host its investments.
