This scoping review investigates the roles of intelligent learning companion systems (LCS) within educational settings, as well as the presences artificial intelligence (AI) embodies within these roles, and their application in education. Employing the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for…

A key feature of embodied education is the participation of the learners' body and mind with the environment. Yet, little work has been done to review the state of embodied education with Artificial Intelligence (AI). The goal of this systematic review is to examine the state of human and AI's triad engagement in education, that is the mind, body,…

For decades, educators have relied on readability metrics that tend to oversimplify dimensions of text difficulty. This study examines the potential of applying advanced artificial intelligence methods to the educational problem of assessing text difficulty. The combination of hierarchical machine learning and natural language processing (NLP) is…

Question classification is a key point in many applications, such as Question Answering (QA, e.g., Yahoo! Answers), Information Retrieval (IR, e.g., Google search engine), and E-learning systems (e.g., Bloom's tax. classifiers). This paper aims to carry out a systematic review of the literature on automatic question classifiers and the technology…

Reviews aspects of the relationship between machine learning and information retrieval. Highlights include learning programs that extend from knowledge-sparse learning to knowledge-rich learning; the role of the thesaurus; knowledge bases; artificial intelligence; weighting documents; work frequency; and merging classification structures. (78…

Defines and delineates hypermedia by examining its relation to the user as a system, an interface, and an environment. Classes of computer systems are described; classes of hypermedia systems are explained; user work components are discussed, including tasks, information, and the environment; and emerging standards and future developments are…

Review of the 1991 literature on subject access in online systems discusses users and subject searching; subject access in online catalogs, including improvement of the database, search processing, the user interface, and user understanding; subject cataloging and indexing; information retrieval; thesaurus and indexing approaches; classification;…

Examines how users interact with text to devise a more effective information retrieval interface. Research in cognitive psychology and information science that relates to the use of metaphors and document categorization is reviewed, and an example of text organization and retrieval by historians is presented.
