5 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 Knowledge Nets – Goals Scenario-based analysis Predict economic impacts of the Semantic 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

6 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 A1 Global Sourcing AM 1.1 Application and Technology Scenarios – 03/04

7 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 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 todays 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

8 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 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

9 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 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

10 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 A1 Global Sourcing AM 1.2 Prototypical implementation – 09/05

11 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 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 distance between two concepts Comparing of competence levels to find the best match Matching allows us to generate the ranking of results Cluster

12 Bizer, Eckstein, Freytag, Heese, Mochol, Oldakowski, Suhl, Tolksdorf Wissensnetze Monitoring Meeting, 15. December 2004 AM 1.2 Application and Technology Scenario Scenario Architecture Information Consumers Information Integration + Matching Information Providers Semantic Matching Engine Crawler RDF Repository Semantic Portal RDF-enhanced Websites SAP HR RAP API Net API Joseki D2R Jena RAP RDF Repository
