New labels in different
languages
Quantify Multilinguality of Data to:
○ Establish a sense of the multilingual reach of Europeana, incl.
distribution of languages
○ Identify the impact of different workflows / processes on
multilinguality of data
○ Take measures to improve multilinguality in data
○ Devise strategies for underrepresented languages
What Could be Measured?
○ Number of (distinct) languages in the metadata
○ Number of language-tagged literals
○ Tagged literals per language
○ Existence of language information fields such as dc:language
○ Consistency and conformity of language information
Multilinguality as a Facet of
Quality Dimensions
12
Completeness
○ This dimension:
○ expresses the number (fraction) of fields present in a dataset
○ identifies non-empty values in a record or (sub-)collection.
○ Multilingual completeness is captured by:
○ Presence of value in dc:language
○ Share of fields with language tags to overall available fields
Consistency
○ Describes the logical coherence of metadata
○ Assesses variety of language values in the dc:language field:
how many distinct values?
○ Contributes to features like language-based facet
Conformity
○ Describes the conformity to a given standard such as ISO-639-2
○ Example: English is expressed as: English, ENG, en, en-uk, …
○ Share of values that comply or do not comply
Accessibility
○ Access to information and data across languages
○ Distribution of linguistic information in metadata
○ Quantifying the language tag
○ The more language tags, the higher the multilingual reach
Dimensions, Criteria & Measures
Dimension Criteria Measure
Completeness Presence or absence of values in fields
relating to the language of the object or
the metadata
Share of multilingual fields to overall
fields
Presence or absence of dc:language
field
Consistency Variance in language notation Distinct language notations
Conformity Compliance to ISO-639-2 Share of values that comply
Accessibility Accessibility across languages
expressed through language tags
Number of distinct languages
Number of languages/Number of
tagged literals
tagged literals per language

Evaluating Data Quality in Europeana: Metrics for Multilinguality

  • 3. Europeana - Platform for Cultural Heritage Material www.europeana.eu
  • 4. ○ Books, newspapers, letters, paintings, photographs, radio shows, films, etc. ○ Text, images, video, audio, sounds, 3D ○ Over 58 million objects ○ > 50 languages Europeana - Facts 4

  • 9. Processes Contributing to Multilinguality dc: subject “subject”@en dc:creator <http://vocab.getty.edu/...> dc:type <http://voc.example./…> dc:subject <http://dbpedia.org/ aSubjectID> dc:subject “Subject” Data from Provider dc:creator new labels in different languages Data added by Europeana: dereferencing step Quantifiable: “term”@language annotation dc:subject New labels in different languages
  • 10. Quantify Multilinguality of Data to: ○ Establish a sense of the multilingual reach of Europeana, incl. distribution of languages ○ Identify the impact of different workflows / processes on multilinguality of data ○ Take measures to improve multilinguality in data ○ Devise strategies for underrepresented languages
  • 11. What Could be Measured? ○ Number of (distinct) languages in the metadata ○ Number of language-tagged literals ○ Tagged literals per language ○ Existence of language information fields such as dc:language ○ Consistency and conformity of language information
  • 12. Multilinguality as a Facet of Quality Dimensions 12
  • 13. Completeness ○ This dimension: ○ expresses the number (fraction) of fields present in a dataset ○ identifies non-empty values in a record or (sub-)collection. ○ Multilingual completeness is captured by: ○ Presence of value in dc:language ○ Share of fields with language tags to overall available fields
  • 14. Consistency ○ Describes the logical coherence of metadata ○ Assesses variety of language values in the dc:language field: how many distinct values? ○ Contributes to features like language-based facet
  • 15. Conformity ○ Describes the conformity to a given standard such as ISO-639-2 ○ Example: English is expressed as: English, ENG, en, en-uk, … ○ Share of values that comply or do not comply
  • 16. Accessibility ○ Access to information and data across languages ○ Distribution of linguistic information in metadata ○ Quantifying the language tag ○ The more language tags, the higher the multilingual reach
  • 17. Dimensions, Criteria & Measures Dimension Criteria Measure Completeness Presence or absence of values in fields relating to the language of the object or the metadata Share of multilingual fields to overall fields Presence or absence of dc:language field Consistency Variance in language notation Distinct language notations Conformity Compliance to ISO-639-2 Share of values that comply Accessibility Accessibility across languages expressed through language tags Number of distinct languages Number of languages/Number of tagged literals tagged literals per language
