Early research on hypermedia learning and Web-based education featured a strong stream of work on intelligent and adaptive textbooks, which combined the knowledge modeling ideas from the field of intelligent tutoring with rich linking offered by the hypermedia and the Web. However, over the next ten years from 2005 to 2015 this area was relatively quiet as the focus of research in e-learning has shifted to other topics and other creative ideas to leverage the power of Internet. A recent gradual shift of the whole publication industry from printed books to electronic books followed by a rapid growth or the volume of online books re-ignited interests to “more intelligent” textbooks. The research on the new generation of intelligent textbooks engaged a larger set of technologies and engaged scholars from a broader range of areas including machine learning, natural language understanding, social computing, etc. In my talk I will review the past and present of research on intelligent textbooks from its origins to the diverse modern work providing examples of most interesting technologies and research results.

2. How to Structure History?
• Pre-History (before 6,000 BCE)
• Ancient history (6,000 BCE – 650 CE)
– Stone Age, Bronze Age, Classical Era…
• Post-classical history (500 – 1500)
• Modern history (1500 – present)
– Early Modern Period (1500 – 1750)
– Late Modern Period (1750 – 1945)
– Contemporary Period (1945 – present)

25. The Values of Concept-Indexed Textbooks
• Navigation support (ELM-ART, InterBook…)
• Content-level adaptation (De Bra)
• Content recommendation (InterBook, ALICE)
• Connect external content (KBS-Hyperbook)
• Concept-based navigation (InterBook)
• Generating guided tours (MultiBook)
• Constructing exercises (MediBook)
26. The End of Classic Age: 3 Bottlenecks
• Huge knowledge engineering
investment to construct a concept-
based textbook
– Experience with ACT-R textbook
– Topic-based models adapted better than concept-
based models
• Lower value of text-only personalization
– ISIS-Tutor and ELM-ART vs. InterBook
• Weak learning modeling approaches
27. Post-Classical Age: Open Corpus
Adaptive Hypermedia (2004-2014)
• Integrate external (Open Corpus) content
– KBS-Hyperbook, SIGUE, AHA!...
• Constructing Hyperspace semi-automatically
– Knowledge Sea
• Navigation support without concept model
– Knowledge Sea II (social navigation)
• Ignoring Textbooks! Focus on ”smart” learning
content
– Exploring topic-based modeling (QuizGuide)
• Automatic concept indexing of learning content
– Special case of programming- NavEx, MasteryGrids

36. Automatic Concept Indexing: C & Java
• C Programming (NavEx and QuizGuide)
– C-code parser (based on UNIX lex & yacc)
– 51 concepts totally (include, void, main_func,
decl_var, etc)

• Topic-based models for prerequisite elicitation
– Use a subsetting approach to divide extracted
concepts into prerequisite and outcome concepts
37. Early Modern History (2013-2016)
• “Real” Electronic textbooks lead the way
• Progress in Semantic Web area and Ontologies
• Progress in Information Retrieval
– Language models
– Data-driven ranking approaches
• Progress in NLP and knowledge extraction
– Topic Models
– Key-phrase extraction
38. OOPS: Content Linking with Ontologies
38
• Topic-based model of an HTML-based
Java textbook automatically extracted
and mapped to a central ontology already
linked to a set of Java exercises
• Mapping serves as a bridge to
jointly interpret learner’s reading
and exercise attempts in terms of
ontology and adapt access to
textbook pages accordingly

43. Example: prerequisite/outcome
separation using supervised ML
• Sources of distant supervision in textbooks
– Supervision Source 1: Unit Cohesiveness
• Our hypothesis is that the author usually explains (i.e.,
outcome) a concept in one place (e.g., a chapter or a
section)
– Supervision Source 2: Unit Titles
• Our hypothesis is that the author of a textbook is more likely
to include the concept’s name in the title of a unit (e.g.,
chapter or section) if the concept is an outcome concept

Prerequisites. In: Proceedings of the 23rd ACM SIGKDD International Conference on Knowledge Discovery and Data Mining, Halifax,
NS, Canada, ACM, pp. 907-915.
