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 1 1

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) 3

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. [2] Cf. [BDG+10]. 2 4

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 9
