Summary
This study introduces a new "Concept Space" model for medical hypertext, improving navigation and reducing reader disorientation. This approach enhances the creation and user experience of digital medical documents.
Area of Science:
- Medical Informatics
- Human-Computer Interaction
Background:
- Hypertext is increasingly used for medical information.
- Traditional hypertext (hyperdocuments) presents challenges in creation, maintenance, and reader navigation, potentially causing disorientation and cognitive overload.
Purpose of the Study:
- To present an alternative model for medical hypertext using a semantic network called "Concept Space."
- To improve the usability and navigation of digital medical texts for both authors and readers.
Main Methods:
- Developed a model where text segments link to contained concepts.
- Created a semantic network ("Concept Space") linking concepts to each other.
- Enabled individualized browsing based on reader interest rather than author-defined links.
Main Results:
- The Concept Space model facilitates individualized browsing of medical hyperdocuments.
- This approach aims to mitigate disorientation and cognitive overload associated with traditional hypertext.
- Offers benefits for both the creators and consumers of medical hyperdocuments.
Conclusions:
- The Concept Space model offers a more intuitive and efficient way to navigate medical hypertext.
- This semantic network approach enhances the user experience by personalizing information discovery.
- Represents a significant advancement in the design of digital medical literature.
