Semantic Engine

We add value here

Microblogging engine: Jaiku

Runs on Google App Engine

Semantic engine

Via REST API

Supported by domain ontologies

Using a semantic index

SemanticIndexing and Search

Performed for every micropost

Message Indexing

Expert Indexing

Message Search

• Morphological variations and ortographic corrections • Mapping to ontology terms + thesauri• Close terms in the ontology• Expanded query with original terms and

(weighted) related terms

Agenda • The miKrow concept• The miKrow approach

– Semantic Indexing – Semantic Search

• miKrow enrichments– Linked Data consumption– ACTIVated miKrow– Contextual miKrow– User collaboration and feedback

• Evaluation / Summary

Evaluation• In-house (iSOCO, SME ~100 people, 4 locations)• ACTIVated version (dummy ontology and examples)

• Microblogging has its own rules and syntax (no straight reuse of a knowledge model)• Microposts may have temporal relevance• User feedback to be considered• Explanations are important (show intelligence)

Summary

• miKrow = microblogging + KM• Intra-Enterprise (domain ontology)• Semantic index, ontology + thesauri queries• Simple approach + Extensions• Two prototypes• Future work: User Collaboration and Feedback

Easy to use Semantically powered
