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

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

Semantic Annotations

• Traditional Web is only understandable for humans• Semantic Web strives to be understandable for

machinesmachine-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

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].

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 Function9
