STI OC Result

1. SEMANACCO
-
a web-based application for accommodation
providers to easily create semantically annotated
descriptions of their accommodations, based on
widespread vocabularies
[1] semantically annotated accommodations

2. Objectives
• Development of an application that enables users to
generate Rich Snippets for accommodation descriptions
• A Rich Snippet is a descriptions of a search result that is
shown below a certain search result
• used to facilitate Search Engine Optimization
 additional information to gain more attention
• Rich Snippets consist of Semantic Annotations
2

3. Semantic Annotations
• Traditional Web is only understandable for humans
• Semantic Web strives to be understandable for
machines
machine-readable descriptions of resources are
necessary.
• This is where annotations are used to markup the
semantics.
 improve accuracy of Web searches (look for only those
pages that refer to a precise concept instead of all the
ones using ambiguous keywords)

4. Semantic Annotations cont.
• At present, three major approaches to apply semantic
annotations compete against each other:
Microformats, RDFa, and Microdata.
• Up to the present, it is not fully clear which approach
will prevail.
• All of them possess some advantages, but also
disadvantages.

9. SEMANACCO
• What is different from other Applications?
– Focus on Accommodations
– Different Vocabularies can be used:
• Schema.org (LodgingBusiness)
• Accommodation Ontology by Martin Hepp and
the Tourism Working Group at STI Innsbruck
• Friend-of-a-Friend (data about persons, e.g.
homepage or skypeID)
– Export Function
– Save / Load Function
