  • This project seeks to leverage the multilingual content of WorldCat. There are more than 300 million records in WorldCat today representing holdings of the world’s libraries. There are also another 200 million articles. Of the 300 million, more than half are in languages other than English.
  • The 300 million records are clustered into works. The records may be in just one language of cataloguing or they may have a mixture of language of cataloguing, e.g. subject heading in more than one language. Parallel records may exist, i.e. records in different languages of cataloguing describing the same resource.
  • The existing architecture is bibliographic record centric. There may be links to author and subject authority records. The work, manifestation and content clusters only contain identifiers, no metadata at present.
  • Three complementary initiatives are in progress concerning multi-lingualism and WorldCat.
  • The first project – generation of metadata at work level to make better presentations. Implementation Q1 2015.
  • The GLIMIR project creates clusters of parallel records for the same manifestation (manifestation cluster) and also clusters for the same content, though the form may be different (print, microform, digital). We are in the process of trawling thorugh the database to make these clusters.

    Only the part in blue will be changed by the multi-lingual bibliographic structure approach
  • Image from Connexion client that shows the short list selection benefing from GLIMIR. So far 103 million records have GLIMIR Ids.
  • Different records in different languages of cataloguing are clustered. The « D »in the last line indicates an LC record. The manifestation cluster includes different records in different languages of cataloguing for the same manifestation. It also includes apparent duplicates that the de-duplication program was not able to confidently merge.
  • Searching with SRU it is possible to search on workID, Content ID (Reproduction1) and manifestation ID. During the development of GLIMIR it was determined that it would be possible in some cases to identify equal content and thus present originals, micorform,re-prints, and electronic editions clustered together.
  • Concerning correcting records coded as “und” = “undetermined”, we expect that we can correct about 7 million by searching for the same title string in other records.
  • Currently when the short list and full displays are created, the system selects the most appropriate record for display. The most appropriate record is determined by its size and the number of associated holdings and it was envisaged to extend this to include the language of cataloguing. But we think we can do much better by questioning the “most appropriate record” concept.
  • Here the first record is catalogued in German but has no significant German content – no subject headings and no notes. There are other richer records that could inform the user better.
  • Hyrid records also mean that significant linguistic information may be buried in other records.
  • This record has subject headings in 3 languages.
  • Build the information to display to users from all available records and show them all relevant holdings. Do not display just one selected record from the work set. Cataloguers too will benefit from this, being able to drill down to actual records where appropriate.
  • This is the theoretical bibliographic structure that will no longer be bibliographic record centric but work centric. All information – authors, notes, summaries, subject headings will be flagged with the language of cataloguing.
  • The work level metadata will be tagged with language for each data element.
    Instead of always showing the data from the main title in the record, the alternative script fields may be chosen for display, depending on what the system can determine about the user, e.g. from IP address range or expressed preference.
    Worldcat.org already includes the ability to change language of display, but the numbers of fields that change will be enhanced and the tabulation of several displays will be improved.
    Consolidate holdings from all records that re applicable to a display (work, content, manifestation level)
  • An Iceland Fisherman, original in French displayed in English UI with Translations table.
  • Same record with Chinese interface
  • The Grand Design; English in Italian UI with Translations table.
  • Same in Japanese interface
  • Instead of working directly with lesser quality records to improve the quality in WorldCat and instead of working with the long tail, we are turning our attention to the most important works and working ways to use the good records to improve the quality.
  • And here’s one title written by each of those “cream” authors – in the original language and script. Likely you’ve heard of all or most of them? But probably in English (click).
    Acknowledgments: Karen Smith-Yoshimura

    We have been focusing on the content that is most likely to be of interest to the most people – translations.
    The cream of the world’s cultural and knowledge heritage is shared by being translated and WorldCat contains many rich cataloguing records for these translations. The Virtual International Authority File, an aggregation of authority records from over 30 agencies worldwide, identifies 15 million unique persons. When we datamine WorldCat, only 7% have written works that have been translated into at least one other language. Only 7,000 have had their works translated into 10 or more languages. This is the “short head” of works that have the most impact on readers worldwide.
  • Translated titles not always consistent, causing work grouping failure.  Sometimes:
    caused by titles without sub titles,
    caused by different forms of uniform title, i.e. in Gujarati and in English (several forms)
    caused by inverting the titles,
    by placing the name Gandhi before “Autobiography”. 

    Some figures:  French – 15 records, 6 work sets; German -  9 records, 9 work sets; Italian 7 records, 5 work sets; Spanish 8 records, 4 work sets
  • We have been datamining WorldCat to generate work-translation ("expression level") records—including the translated title and translator with links to the original work and the author—and adding them to VIAF (Virtual International Authority File), flagged as "xR". Here is a concrete example of the impact – Jane Austen’s Pride and Prejudice originally had 13 translations associated with it; after we generated the xR records for other translations as datamined from WorldCat the number increased to 50.

    So far we have added 2 million xR records to VIAF. About the same as the UNESCO database after 25 years (!)
  • UNESCO has also been interested in identifying and aggregating translations world-wide for an “international bibliography of translations” – they have been at it for over 80 years! Their database represents entries contributed from UNESCO members since 1979 and contains 2 million entries.
  • Yet when we compare the results for a specific work, like Anatole France’s Crime de Silvestre Bonnard, we can see that the contributions OCLC member libraries have made, through WorldCat, is far greater that all the work invested so far by the UNESCO member states. VIAF, with the xR records datamined from libraries’ contributions to WorldCat supplementing those from VIAF contributors, lists 29 translations in 28 different languages.
  • We are now working on enhancing the VIAF display to make the contents of title records more visible. This is a mockup of a VIAF Consolidated display – shows work with expressions summary. It shows the title as it is translated in each language.
  • This is a mockup of the full expressions summary for the work Pêcheur d’Islande by Pierre Loti.
  • This is a mockup of a VIAF Full display – showing different translations of the title, plus the translator and the earliest determined publication date of each.
  • Acknowlegments: Karen Smith-Yoshimura & Dan Benson
    The relationship of a work (with an author) and its associated translations (with their respective translators) is relatively straight-forward. This diagram captures the relationship in two reciprocal links, one from the original Chinese book (blue box) through its property HasTranslation pointing (with blue arrows) to each translation (red boxes), and one from each translation back to the original Chinese work (red arrows) through the property IsTranslationOf . A work can have any number of translations, and there can be multiple translations into the same language which is why identifying the translator is so important.

  • Acknowledgements: Karen Smith-Yoshimura
    Machines access VIAF far more than humans. To leverage all the work done by the OCLC cooperative we want to share the relationships we’ve established between original works and their associated translations with the semantic Web. Here is a sample markup of an original Chinese work written by Gao Xingjian, a Chinese Nobel Prize laureate for literature, and one of the translations of his work into English. We marked this up with schema.org but there are two new terms we are proposing, shown here: translator and translationOfWork.

    This work will help us better understand the extent to which information is shared across cultures. Here are some questions we should be able to answer soon!

    More information on this project is available on the OCLC Research website at the link shown.

    Just think. How many of the 150+ million records that are for non English language works are actually translations of English language records. And how many of the English language records are also translations? It could be as high as 25%?

    Once we have these records generated, it will open many new possibilities.

    Also, we know we have 300 million records, but how many real resources do we have? GLIMIR will produce these figures.

    We are just starting…
