miKrow: Micro-Knowledge Management In a nutshell… Semantic Intra-Enterprise Micro-Knowledge Management System

Collaboration Interoperability and Access to Information Semantic Web Web 3.0 Enterprise 3.0 Web 1.0 - - + + Enterprise 3.0: Collaborative aspects of Web 2.0 + Semantic Technologies applied to the enterprise Web 2.0 Enterprise 2.0

The miKrow approach We take something existing Microblogging Engine + 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

Semantic Indexing and Search Performed for every micropost messages + experts

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
Query built from user input by:

Expert Search

In Use… Before posting

In Use… Related messages New suggestions stream Related experts Terms found

Enriching the basic prototype

User Collaboration and Feedback

Linked Data consumption Linking Open Data cloud diagram by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/ Entity recognition It helps keeping knowledge base up to date…

Using a external service Consuming Linked Data

In Use… Linked Data Entity Recognition

ACTIVated miKrow It helps tackling the cold-start problem…
Working Context
Resource
Knowledge Process

ACTIVating miKrow Using a external service

In Use… Related working contexts, processes and resources…

In Use… … connected to the ACTIVE system

Contextual miKrow Context data (e.g., location) Improving the index with contextual information

miKrow in context Using a external service

In Use… Location used as contextual information

User (I): Collaboration Spheres Future Work! Finding the ad-hoc relationships within the system (Result from )

(Result from ) User (II): Feedback Future Work! Leveraging User Feedback to improve the suggestions Ratings in a semantic format through API with LUF

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
