Knowledge Nets – Goals • Scenario-based analysis • Predict economic impacts of theSemantic Web technologies on E-Commerce • Business viewpoint • Predict impacts on markets and value chains • Estimate feasibility based on participants’ interests and business models • Technological viewpoint • Derive requirements for the technological infrastructure • Evaluate current technological developments
A1 Global Sourcing • AM 1.1 Application and Technology Scenarios – 03/04 a
AM 1.1 Application and Technology Scenarios B2C / HR-Domain • Business to consumer e-commerce enhanced with Semantic Web technologies • Employment market enhanced with Semantic Web technologies • Analysis of today’s applications • Job postings are written in the form of free text using uncontrolled vocabularies • The meta-search engines available perform searches on a full text basis • The search results are limited in their ability to provide offers that match the precise needs of their clients • There are many different existing taxonomies for the classification of job posting
AM 1.1 Application and Technology Scenarios HR-Domain • Scenario • Information providers publish in RDF according to common ontologies • Semantic portals collect the information and offer semantic matching services. • Implications • Job Seeker (employee) • Increased market transparency • Higher precision of search results • Job Poster (employer, job portals, state job centre) • Open n:m communication – increased market transparency • Costs reduction • Changes in the business models
AM 1.1 Application and Technology Scenarios HR-Domain Ontology • We use an ontology for recruitment scenario that is based on JobPositionPosting and JobPositionSeeker from HR-BA-XML • Information is represented in OWL using controlled vocabularies
A1 Global Sourcing • AM 1.2 Prototypical implementation – 09/05
Cluster AM 1.2 Application and Technology Scenario HR-Domain – Matching • Semantic Matching – combines annotations using controlled vocabularies with background knowledge about a certain application domain • Comparing job descriptions and applicants’ profiles based on their semantic similarity (not merely relying on the containment of keywords) • Total similarity is the sum of the cluster similarities • Similarity determined by the distancebetween two concepts • Comparing of competence levels to find the best match • Matching allows us to generate the ranking of results
