Abstract

We present a graphical, anatomy-driven navigationinterface called VINSIA for information delivery at thepoint of care. VINSIA has been developed by expandingSemantic MediaWiki (SMW [1]) to organize and classifyinformation using four axes: Anatomy, Location, Topicand User. These axes provide the building blocks forfaceted information access: any content item in VINSIAcan be accessed through any facet with limited need forentering a search term. Preliminary testing of a pilot sitedemonstrates the feasibility and advantages of VINSIAfor high-precision, quick navigation to targeted contentitems.

Conclusion

Information in VINSIA is categorized into four axes:Anatomy, Location, Topic and User. The Anatomy axiscaptures the anatomical hierarchy based e.g. on FMA. TheLocation axis captures physical locations in a hospital settingwhere the information is used or needed. The Topicaxis captures the specific types of information. Finally theUser axis captures a hierarchy of user permissions foraccess control.We use Semantic MediaWiki [1] as the backgroundframework for implementing the axes.

3. Click Aortic valve

"Clinical Management"

VINSIA provides a high-precision, visual, anatomy basednavigation interface for clinicians in perioperative and critical care environments. The efficiency of VINSIA is measured by the total number of primitive computer interactions (key strokes andmouse drags or clicks). VINSIA is also semanticdriven because of its Semantic MediaWiki implementation environment. Importing high quality content into VINSIA is a critical prerequisite for fulfilling its function. To support this, VINSIA provides an interactive interface for qualified users to upload contents and tag them with categories in every facet.

For example, to access contents specifically on aortic valve, one clicks the “heart” on the “human body”, followed by the click sequence “cardiac valves” → “aortic valve”→ “clinical management” (Figure 2). This access mode only involves mouse clicking without any typing.

Another way to get information in specific categories are by Category Search, as illustrated in Figure 5 below:
