Objectives and expected outcomes The main objective of the Europeana Fashion Best Practice Network is to build a thematic aggregator on fashion, putting emphasis on the quality, the variety and granularity of content that will be delivered to Europeana, and producing a significant increase of the fashion related content in it.

Aims and results of the project  aggregate 700.000+ digital items of fashion content to Europeana

  improve interoperability in the fashion community

 create a specialised access point for fashion content

 develop case studies for the exploitation of fashion material

 build consensus and raise awareness on best practices

The composition of our project consortium The Europeana Fashion Best Practice Network will encompass 22 partners from 12 European countries, which represent the leading European institutions and collections in the fashion domain.

Europeana Fashion data model (EDM-fp) Main features:

•  EDM profile

•  Added fashion-related elements (e.g. color)

•  Suitable for non-object entities (e.g. exhibition)

•  Use of specific relationships (e.g. between a dress and an exhibition)

•  Use of controlled vocabularies

Europeana Fashion Thesaurus The Europeana Fashion project has created a multilingual thesaurus in 11 languages, for fashion and fashion-related concepts. We structured it in a faceted way: Materials, Techniques, Object types and Colors. The thesaurus has been developed: •  as an aid for data entry •  as a knowledge base (open to

internal and external users) •  as a search enhancement tool The Europeana Fashion Thesaurus is based on the Art and Architecture Thesaurus (AAT)

Data ingestion workflow

•  Each partner extracts data from his

own database

•  Using an open source ingestion tool (MINT) metadata are uploaded and transformed in a common data model (EDM-fp)

•  Digital objects are uploaded into the Europeana Fashion repository

Rights management underpins everything we wish to achieve for Europeana Fashion. That’s why we developed the IPR best practice guidelines: •  Key to achieving project objectives •  Clarity for content holders •  Clarity for end users

Fashion edit-a-thons

What is an edit-a-thon

An edit-a-thon is “a scheduled time where people edit Wikipedia together, whether offline, online, or a mix of both; typically focused on a specific topic, such as science or women's history” *

* https://en.wikipedia.org/wiki/Wikipedia:How_to_run_an_edit-a-thon

What we have done till now... Eight edit-a-thons organised:

1.   Nordiska Museet, Stockholm, 22 March 2013.

2.   Centraal Museum Utrecht, 13 May 2013.

Next Steps •  Data semantification

•  Data linking

•  Ontology development

•  Semantic query answering

•  Integration in the thesaurus of visual concepts

Semantic Data Access Free text descriptions

id:VA_T.127-1933 dcterms:type “dress” may be very informative (large text descriptions) low level data-access: keyword-based search

Search for “dress” hidden semantics

Thesaurus

id:VA_T.127-1933 dcterms:type <Dress> <Dress> subClassOf <Main_garment>

high-level data access: term-based search Search for <Dress> or <Main_garment>

clear semantics Formal ontologies

<EveningDress> subClassOf <LongDress> and hasMaterial .<Silk> properties, more complex axioms full semantic data access: concept-based search

Search for <EveningDress> rich semantics

Data Semantification Extract thesaurus/ontology concepts from free text descriptions

Data Semantification process 1st step

•  Retrieve text labels for all thesaurus concepts in each language •  Construct a table with a new row for each thesaurus concept

•  URI •  Textual label •  Respective EDM-fp property

•  The set of textual labels play the role of the vocabulary to look for in the free text descriptions

Data Semantification process 2nd step

•  Lookup the words that appear in the free texts that have been entered as values for the several EDM-fp properties

•  NLP techniques •  String (regular expression) matching

•  For each match with the vocabulary output a row: •  Source EDM-fp metadata property •  Matched thesaurus URI •  Respective EDM-fp property for the matched URI

3rd step

•  Export the enriched data

Data Linking •  Similar to semantification, but uses external resources. •  Some EDM-fp property values may be linked to the Linked

Open Data Cloud (e.g. DBpedia) •  Names of persons (creators, designers, photographers) •  Names of places

place: <http://dbpedia.org/resource/Great_Britain>

Enriched data The enriched data are currently exported as RDF files

•  One RDF file for each item •  Replaces the original RDF/XML file generated by MINT •  Contains the enriched EDM-fp metadata

Things to check: •  Extension of the thesaurus to cover more concepts •  Verification of the enriched data by the providers •  Handling of original values (in cases of inconsistent values) •  Export to the Fashion portal.

Ontology developmnet The Fashion Thesaurus is just a taxonomy

•  In a formal ontology axioms interconnecting concepts can be defined

•  Rich semantics and full semantic data access Classes and Taxonomy:

Extension of the Fashion Thesaurus Properties:

hasPart, hasTechnique, hasMaterial, hasColor, depicts, ... Axioms:

Definitions of common terminology concepts Organza ⊑ SheerFabric ⊓ ∃hasTechnique.TaffetaWeave Sateen ⊑ Textile ⊓ ∃hasTechnique.SatinWeave ⊓ ∃hasMaterial.CottonFiber Brass ⊑ Alloy ⊓ ∃hasMaterial.Copper ⊓ ∃hasMaterial.Zinc

Definitions of useful, complex concepts GoldenRing ⊑ Ring ⊓ ∃hasMaterial.Gold SatinDress ⊑ Dress ⊓ ∃hasTechnique.Satin BrownLeatherBelt ⊑ Belt ⊓ ∃hasMaterial.Leather ⊓ ∃hasColor.Brown EveningDress ⊑ ...

Ontology developmnet A mainly manual process

•  Domain expert •  “Complete” description of an entire domain

Data-driven automatization

•  If data are available, use them to get information about the domain. •  Very frequently occurring phrases may correspond to useful

concepts.

Ontology refinement tool

•  Semi-automatizes the ontology development •  Data-driven enrichment of an existing ontology

•  Process free text descriptions. •  Visually explore the actual data. •  Define new axioms for frequently occurring complex concepts

Ontology Refinement Tool How the tool works (preliminary steps): •  Load an ontology.

•  Map the ontology concepts to existing instances residing in a database or a triple store.

•  Declare the instance properties that should be retrieved and the properties whose textual contents should be retrieved and analyzed.

•  E.g. for the Europeana Fashion data: •  Description (analyze) •  Materials (retrieve) •  Techniques (retrieve)

How the tool works (further steps):

•  Select a concept from the Ontology Concepts Tree.

•  The tools retrieves automatically from the database the mapped instances and analyzes their properties.

•  Performs NLP processing in order to extract frequent noun phrases and adjectives (Terms).

•  The terms, along with their frequency of appearance statistics, are displayed in the Analysis Results Table.

•  Define a sub-concept of the selected concept by using the graphical interface of the Ontology Sub-concept Definition Panel.

•  The instances that match the new definition will be automatically classified as instances of the new sub-concept.

Work still to be done •  Completion of Fashion Ontology

•  Enrichment with “useful” axioms for user queries •  E.g. Evening dark-colored dress, Non-extravagant haute

couture dress

•  Integration of the Fashion Ontology with the Fashion Portal •  Query construction interface based on the ontology •  Integration of the enriched data •  Integration of reasoning service
