Background – ChemZentTM is the CAS implementation of Chemisches Zentralblatt

Chemisches Zentralblatt is •  A set of books that covers over three million abstracts from patents

and journals •  The first and oldest abstracts journal in chemistry •  The only comprehensive abstract journal prior to 1907 •  An extensive source of detailed abstracts covering the chemical

literature from 1830 to 1969 •  Until now, only available in German


Why search through old musty books when you can just use SciFinder®…


…to access ChemZent for a window into the published literature of early influencers of chemistry


ChemZent: A historical, archival chemistry collection now searchable in SciFinder

ChemZent •  Allows users to access the entire Chemisches Zentralblatt collection in one

place, searchable in English with indexing for substances and concepts •  Takes advantage of the inherent, easy-to-use functionality of SciFinder •  Provides searchability across 140 years of Chemisches Zentralblatt abstracts

without the need to know the year of interest •  Covers many authors who formulated the theories and hypotheses that

shaped the foundation of today’s chemistry


ChemZent provides immeasurable value to researchers and institutions around the world

•  Libraries pursuing completeness for historical record

•  Intellectual property professionals interested in early patentability information

•  History of chemistry researchers interested in the birth of chemistry as a science

•  Professors looking to expand their curriculum

•  Process chemists and scientists exploring simpler chemistry methodologies

Finding ChemZent records in SciFinder is easy


Reviewing the answers, we can see that Rosalind Franklin did a lot more than help with the discovery of the structure of DNA


Eugène-Melchior Péligot – isolation of Uranium 1841


Henri Becquerel – radioactivity of Uranium


In another leap forward, Enrico Fermi conducted significant research on radiation and radioactivity


Iconic Machine Translations made it possible to bring ChemZent to market within a year of idea inception

•  Image extraction •  Optical character recognition •  Abstract identification •  Machine translation •  Positioning, indexing and

packaging

Project overview

Project statistics •  803,734 PDFs

processed •  3,000,000+ records

extracted and translated


Large scale digitization and translation of 140 years worth of German chemical information – journals and patents – for indexing and search. Image-based PDF documents were digitized (via OCR), extracted into individual records, separated into fields, translated and packaged according to XML specifications.

Record extraction •  Machine learned-based extraction

algorithms work on cleaned OCR output, using patterns, keywords and formatting information

•  This separation of records was the most challenging aspect of the project

•  Identification of the reference data and fielding were treated separately

•  Once identified, references were fielded according to patterns and key terms

•  Challenges were presented by relative inconsistency in layout

State-of-the-art proprietary technology – Iconic “Ensemble Architecture”

Translation Separation •  Separate translation processes for

processing titles and abstracts •  Less “reordering” required given

telegraphic style in titles

Dictionaries & Feedback •  Incorporation of fixes and technical

glossaries provided during pilot evaluations and ongoing quality audits by CAS chemists

Entity Identification •  Identification of chemical names, e.g.,

1,2-DICHLOROCYCLOHEXANE to ensure processing as a single entity

Machine translation to English


German to English MT for TITLES German to English MT for ABSTRACTS

A real challenge

Acronyms, (spurious) abbreviations, misspellings, language evolution – the collective bane of translation automation

•  Über vs. Ueber


Abbreviation Full form Translation But…! F. Schmelzpunkt Melting point F = flourine

S. Säure Acid S = sulfur

u. und and with exceptions like…

u. Mk. unter dem Mikroskop under the microscope

Abbreviations found in the first 10 years worth of documents


Summary and conclusion

•  Successful collaboration –  New product and sales approach for CAS

•  Machine translation and one-time purchase rather than subscription –  Iconic applied translation systems and proprietary ensemble architecture

to a complex subject •  ChemZent exceeded sales expectations for year one

–  Academic and commercial customers •  Iconic and CAS are continuing collaboration on other projects
