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 1.2 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
