Data Collection
0Python LinkedIn Library0 https://github.com/ozgur/python-linkedin
0Profile.py0 Developer’s own profile is easy to extract0 Or use search API to find other person’s profile
0 Job_extraction.py0 According to the level of the Linked-In account, the query
gives different numbers of jobs’ information0 The result is sorted by the timestamp of posting
Data Collection
0Example of Profile(profile.json)
Data Collection0Example of Job Description(job_description.json)
Build Keyword Set
0 The skills Keyword Set (profile.json)0 Good to use
0 The Job Description has no Keyword Set (job_description.json)
0 Need to analyse0 AlchemyAPI

Build Keyword Set
0Generate The Keywords Set from job description (Job_skills.json)0 Example:

0 Convert the .ttl format to .owl by using the “OWL Syntax Converter” developed by the University of Machester0http://mowl-power.cs.man.ac.uk:8080/converter/
0 Preload into the Web-Karma
Build The Relationship 0The HR ontology
Build The Relationship 0Build Profile Linkage
Build The Relationship 0Build Linkage for Job skills
Build The Relationship 0Build Linkage for Job Information
Compute the Matching Score
0Load the profile.rdf and job_skills.rdf to Jena
0Do the SPARQL query, count the number of the items which are same.0 Example Query
Query Exampleselect ?name where { ?y ?id . filter (?id = '5831587').?y ?x .?x .?x ?z .{ ?x ?name filter (?name = 'C++')} union { ?x ?name filter (?name = 'OpenGL')} union { ?x ?name filter (?name = 'Photoshop')} union { ?x ?name filter (?name = 'Windows')} union { ?x ?name filter (?name = 'Visual Studio')} union { ?x ?name filter (?name = 'Linux')} union { ?x ?name filter (?name = 'UML')} union { ?x ?name filter (?name = 'JavaScript')} union { ?x ?name filter (?name = 'Cocos2d')} union { ?x ?name filter (?name = 'Objective-C')} union { ?x ?name filter (?name = 'C')} union { ?x ?name filter (?name = 'OS X')} union { ?x ?name filter (?name = 'Computer Vision')} union { ?x ?name filter (?name = 'iOS')} union { ?x ?name filter (?name = 'Machine Vision')} union { ?x ?name filter (?name = 'Cocoa Touch')} union { ?x ?name filter (?name = 'Hibernate')} union { ?x ?name filter (?name = 'Xcode')} union { ?x ?name filter (?name = 'Mac OS X')} union { ?x ?name filter (?name = 'LaTeX')} union { ?x ?name filter (?name = 'MySQL')} union { ?x ?name filter (?name = 'Java')}}
What’s New0 No open-source job application provides job semantic matching
0 All the job hunting web services just provide the searching result according to the latest creation time of the job position.
0 How to convert Json to RDF format0 We checked lots of converters however few of them provide this
feature, but most of them can only convert semantic file format.1.RDF Translator: http://ebusiness-unibw.org (NG)2.Karma:http://github.com/InformationIntegrationGroup/Web-Karma (Good)
