4 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Knowledge Nets (Subproject A)

5 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 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 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Global Sourcing – Application and Technology Scenarios (AM 1.1)

7 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 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 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Application and Technology Scenarios HR-Domain Szenario 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 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 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 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Application and Technology Scenario HR-Domain – Matching Matching is a process of determining of graph similarity Graph similarity is the sum of the cluster similarities Calculation of similarities for single node Taxonomic similarity Attributive similarity Matching allows us to generate the ranking of results

11 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Scenario Architecture Information Consumers Information Integration + Matching Information Providers Semantic Matching Engine Crawler RDF Repository Semantic Portal RDF-enchanced Websites RAP RDF Repository SAP HR RAP API Net API Joseki D2R Jena

12 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Evaluation toolkit (AM 3.1)

13 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Evaluation Toolkit Semantic Web Framework RAP – RDF API for PHP leading RDF toolkit for PHP developers features for parsing, manipulating, storing, querying, serializing, and serving RDF models Open source, 1200 downloads D2R D2R MAP - declarative language to describe mappings between relational database schemata and OWL/RDFS ontologies D2R Processor - exports data from a relational database into RDF Open source, 300 downloads

14 Tolksdorf, Bizer, Eckstein, Heese, Mochol, Oldakowski Knowledge Nets Monitoring Meeting, 21. June 2004 Application and Technology Scenarios Surveys Current state of data exchange in the sectors Automotive retail Consumer packaged goods (CPG) retail Telecommunication Liberalization of business markets Semantic Web trust architecture Repositories and Tools for RDF/S RDF Algebra Mapping of query statements to algebra enabling efficient query evaluation on huge amounts of RDF data Modelling and Generation of Ontologies Modeling of OWL Ontologies with UML
