Saha - Browser Based Semantic Annotation Tool
Page updated: 11.05.2011
Saha is a browser-based annotation tool, which can be used to annotate e.g. web-pages and other documents on the web. With Saha, annotation process can be easily distributed and it can be used without installing any annotation software on user's computer.
Annotations are stored in a database, from which they can be retrieved for use in semantic applications, like portals using multi facet search paradigm. Saha uses semantic web technologies such as OWL and RDF(S).
Saha's user-interface consists of property-input-form, which can be easily configured for the annotation-schema being used. Different kinds of resources can be used as values of the properties:
- Resources defined in external ontologies and fetched to the annotation using the Onki Ontology Library Service
- Resources defined in other external sources, such as CultureSampo
- Instances of classes defined in the annotation-schema
- Literal values
Saha has undergone several major development versions. Demo of the current Saha (SAHA3) is available here. Please note that while browser interoperability is a design goal, some advanced features might not work properly in older versions of Internet Explorer.
Basic documentation about Saha is available in the Saha Technical Report
