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

5 Comparison of Microformats, RDFa and Microdata FeatureMicroformats 1.0RDFa 1.1Microdata 1.0 Relative complexity LowHighMedium New attributes No (class, rel, rev of HTML) vocab, typeof, resource, property, prefix, content, datatype, about, rel, rev, inlist itemscope, itemtype, itemprop, itemref, itemid standardizedNoYes Employment of multiple external vocabularies Just oneUnlimited amount Only in different items or with absolute URIs HTML5 time element support Only with Microformats 2.0 NoYes Cf. [ToLa09], [Spor11], [Hick11], [Sche11], [AHS+12], [ABM+12], [Sche12a], [Spor12], [ABP+12], and [Micro12a]. 5

6 Which applications are out there to generate Semantic Annotations?

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
