Application Profiles
• Standards are too general – I don’t need all that fuzz
• Standards are too restricted – they don’t let me do what I want
• Solution: Application Profiles!
![Page 7: 10052012 luc vervenne synergetics van syntax portfolio naar semantische uitwisselbaarheid](https://reader035.vdocuments.pub/reader035/viewer/2022062405/5563905ed8b42adf7a8b543a/html5/thumbnails/7.jpg)
Make My Day!Make My Profile – it‘s easy!
• Making mandatory what I do want• Making optional what I tolerate• Remove what I don’t need• Add what I need
• Next step: • Convince your industry sector • Agree• Share
![Page 8: 10052012 luc vervenne synergetics van syntax portfolio naar semantische uitwisselbaarheid](https://reader035.vdocuments.pub/reader035/viewer/2022062405/5563905ed8b42adf7a8b543a/html5/thumbnails/8.jpg)
Making My Profile – Oh so tricky!
• My own extensions • Mixing and matching many profiles• All referenced files must :• exist• validate against another profile or one of a few…
• And…• you have to find out which one to use…• the imsmanifest.xml must exist !!
![Page 9: 10052012 luc vervenne synergetics van syntax portfolio naar semantische uitwisselbaarheid](https://reader035.vdocuments.pub/reader035/viewer/2022062405/5563905ed8b42adf7a8b543a/html5/thumbnails/9.jpg)
Prerequisites of Profiles
• A community of stakeholders
• Acquaintance with:• their needs…• their willingness to agree…• their willingness to implement!!!
• STEPS: Success of application profile depends on implementers, data providers and data consumers
YOU BETTER HELP THEM!!

Conformance Testing
• Test so that data conforms to YOUR profile• Problem:• Each profile requires a specific test system• Test system development is expensive
• Solution:• Capture profile in machine readable form• Configure generic test system

Purpose: Semantic Comparison of Labour Market Data
Compare real-world employability & employment data versus Reference Data of Competences, Occupations, Qualifications, …
Allows the meaningful search, assessment or match of experience, professional activities, skills & competences by using :• Domain Semantics (Annotated Reference framework data) • Linguistic Semantics (Unstructured data using NL processing) • Created individually (personal employability data)• Created at company level (vacancies, job profiles, …)
![Page 18: 10052012 luc vervenne synergetics van syntax portfolio naar semantische uitwisselbaarheid](https://reader035.vdocuments.pub/reader035/viewer/2022062405/5563905ed8b42adf7a8b543a/html5/thumbnails/18.jpg)

Approach
• Knowledge management• Knowledge encoding (knowledge bases)• Knowledge-based data processing
• Annotation• Comparison• Interoperation• Inference
• (Natural Language) Data processing• Interpret data dynamically• Capture data individuality and specifics
![Page 19: 10052012 luc vervenne synergetics van syntax portfolio naar semantische uitwisselbaarheid](https://reader035.vdocuments.pub/reader035/viewer/2022062405/5563905ed8b42adf7a8b543a/html5/thumbnails/19.jpg)

Data, Knowledge & Semantics
1. Data : experience, goal, competence, preference, hobby, training, job, task
2. Knowledge : frameworks, expert rules, models, ontology
3. Semantics : compare Data + Knowledge for semantic operations: • Data management• Knowledge management• Knowledge-based data management• Data-oriented knowledge management
Two kinds of Semantics are involved:
Precompiled: Static, knowledge-based operation
= knowledge semantics
Extracted : Dynamic, in real-time in data management
= data semantics

: Data & SemanticsThe Employability data from : (1) Candidates (employabilityPortfolio™, CVs, EuroPASS, HR, educational, Recruiting or Public or Private Employment Systems (2) Vacancies are indexed & correlated against vocational/occupational qualification and competency catalogues.
This demo is based on the French ROME 2.0 catalogue. However such National catalogues (NOS/SSC) can be enriched with information from other European catalogues.
All vocational categories and qualifications and their respective competency / skills profiles are correlated.
A competency profile is required for the performant execution of professional/vocational ”activities”
Each activity is abstracted using concepts and their relations

Conclusion
• The “Activity Semantics” extraction method makes use of Natural Language Technology :• Abstraction : Extract universal semantics from different competenvy
descriptions• Interpretation : Skills and Competency extraction from
employabilityPortfolios™, texts, CVs, vacancies and … Regional Employability Platform enabled systems!
• For this demo we used (anonymised) real life data from 13.000 candidates and 13.000 vacancies.
• The Activity Semantics method is based on its own ABAS Ontology• Semantic annotation & enrichment of existing ESCO and other European
occupation, vocation, qualification and competency frameworks (ROME, COLO, NOS, UKCES, SSC, QCF, …etc)
• This semantic method allows for considerable refined decision making when searching for the right candidate or vacancy, based upon a set of required or desired competencies.

• Comparison• Input: Semantic DNAs
• Output: Scores of Similarity, Difference, Equivalence. These are the basis for semantic matching• Robust text understanding technology
• Language parsing and interpretation• Customisable and optimisable• Languages (French, English currently, Dutch coming up)
