Introduc4on    

Page 2: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

What  are  controlled  vocabularies?  

•  organized  arrangement  of  words  and  phrases    

•  used  to  index  content  and/or  to  retrieve  content  through  browsing  or  searching    

•  include  preferred  and  variant  terms    

•  have  defined  scope  or  describe  a  specific  domain  

h@p://vocabularyserver.com/glossaries/ge@y/index.php      

Page 3: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

Thesaurus    =  a  controlled  vocabulary  arranged  in      a  known  order  and  structured  so  that      the  various  rela4onships  among  terms    are  displayed  clearly  and  iden4fied  by      standardized  rela4onship  indicators.    

 Important:  •  ISO  25964  is  a  standard  for  building  thesauri  •  SKOS  is  a  W3C  recommenda4on  designed  for  representa4on  

of  controlled  vocabularies  and  is  built  upon  RDF  and  RDFS.  It  allows  publica4on  of  such  vocabularies  as  linked  data.

ISO  25964  

•  Part  1:  Thesauri  for  informa>on    retrieval          -­‐  published  in  2011        -­‐  developing  a  thesaurus  (mono-­‐  and                                  

       mul4lingual)        -­‐  replaced  previous  standards  ISO  2788/5964        -­‐  includes  data  model  and  XML  schema  

•  Part  2:  Interoperability  with  other  vocabularies          -­‐  published  in  2013        -­‐  recommenda4ons  for  the  establishment  and  maintenance  of    

     mappings  between  mul4ple  thesauri,  or  between  thesauri  and          other  types  of  vocabularies    

Data Model

http://www.niso.org/schemas/iso25964/

Page 5: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

SKOS  Simple  Knowledge  Organiza4on  System   http://www.w3.org/2004/02/skos/intro SKOS  provides  a  standard    way  to  represent  knowledge    organiza4on  systems  using  the  Resource  Descrip4on  Framework  (RDF).    Encoding  this  informa4on  in  RDF  allows  it  to  be  passed  between  computer    applica4ons  in  an  interoperable  way.    Using  RDF  also  allows  knowledge  organiza4on  systems  to  be  used  in  distributed,  decentralised  metadata  applica4ons.  Decentralised  metadata  is  becoming  a  typical  scenario,  where  service  providers  want  to  add  value  to  metadata  harvested  from  mul4ple  sources.

Page 6: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

Mul4lingual  vocabulary  issues  (examples)  

•  structural  problems:  conceptual  systems  differ  in  the  various  languages  

•  equivalence  problems:  lexicalisa4on  of  concepts  differs  in  different  languages    

• eg.  bone  –  fish  bone  (en);  Knochen  –  Gräten  (de)[1];  • intra-­‐  and  inter-­‐language  problems;  terms  differ  in  meaning  (homographs)  given  term  can  have  more  than  one  meaning  in  a  language  

• eg.  Turkey  (country)  and  turkey  (animal)  [1]  h@p://www.dsoergel.com/cv/B67.pdf  20th  August,  2014    

Page 7: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

Federated  Model  

•  LoCloud  vocabulary  based  on  federated  model  •  having  independent  vocabularies  for  various  languages  in  the  same  domain  (no  one  language  is  dominant)  

•  alignment  of  vocabularies  via  concept  iden>fiers,  end-­‐user  can  search  in  all  linked  indexing  vocabularies  

•  AIT  experimental  applica4on  based  on  TemaTres  Vocabulary  Tool  

Page 8: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

TemaTres  ...  •  supports  distributed  management  models    •  ensures  consistency  and  integrity  of  data  and  rela4onships  between  terms    

•  has  features  specially  designed  to  provide  data  traceability  and  quality  control  in  the  context  of  a  controlled  vocabulary    

•  supports  the  analysis  and  categorisa4on  of  terms  for  search    

•  enables  vocabularies  to  be  represented  in  a  wide  range  of  metadata  standards  relevant  to  knowledge  management     http://www.vocabularyserver.com/

Page 9: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

TemaTres  func4onali4es  •  No  limits  to  number  of  terms,  alterna4ve  labels,  levels  of  

hierarchy,  etc    •  allows  import/export  of  data  in  text  or  SKOS  format  •  mul4lingualism  •  SPARQL  endpoint  •  rela4onships  between  terms  •  notes  •  user  management  •  Reports  •  Addi4onally:  meta-­‐terms:  define  facets,  collec4ons  or  arrays  of  terms,  expose  vocabularies  

with  powerful  web  services,  search  terms  sugges4on  (did  you  mean...?),  display  terms  in  mul4ple  deep  levels  in  the  same  screen,  user  management,  duplicate  and  free  terms  control,  mul4lingual  terminology  mapping  etc.  

Page 10: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT

Why  TemaTres?  •  Fast  to  use  •  Making  vocabularies  available  as  Webservice  in  the  enrichment  process  

•  Many  vocabularies  (like  UNESCO,  Gemet,  PICO)  have  already  been  established  with  this  tool  and  are  usable  in  the  LoCloud  infrastructure  (h@p://www.vocabularyserver.com/vocabularies.php  ,  175  vocabularies  available)  

•  Addi4onally  own  vocabularies  can  be  created  •  Best  star4ng  point:  Skos-­‐file  for  import  

Page 11: LoCloud Vocabulary Services: Thesaurus management introduction, Walter Koch and Gerda Koch, AIT
