AGROVOC


AGROVOC

• In 1980: • AGROVOC thesaurus was born• It was in 3 languages: English, Spanish, French• It was a paper publication

• In 2012: • AGROVOC is an RDF/SKOS resource• AGROVOC is available in 21 languages• 4 languages are under development


Number of terms per language in AGROVOC

Linked Open Vocabularies


AGROVOC LOD record


The problem Thesaurus editors old fashioned, not viable

to edit SKOS

Ontology editors to complex one one side, not specific enough on the other

None of the existing tools had an integrated workflow environment

No possibility of collaborative editing, most tools were not web applications


The solution: VocBench

Is a web-based working environment for managing the AGROVOC Concept Scheme

Facilitate the collaborative editing of multilingual terminology and semantic concept information

It includes administration and group management features

It includes workflows for maintenance, validation and quality assurance of the data pool

It is accessible freely to everybody to facilitates collaborative editing

VocBench 2.0


Coming features


VocBench 2.0

VB 2.0 will natively support SKOS

Separation of the business and presentation layers from the data layer

This allows VB to be attached to any SPARQL-compliant triple-store database (Sesame, Jena, Allegrograph, OWLLim)

First release of VB 2.0 will retain the same interface as that of VB 1.0

VB 2.0 will incorporate all the functionalities available in VB 1.0

Multi-user support, roles and right administration, and publishing work flow management will inherited from VB 1.0.

Current Protégé implementation of VB 1.0 will be replaced by Semantic Turkey

All the business logic and data access layers related to ontology management will be handled by Semantic Turkey

HOME - RECENT CHANGES

• Lists all the changes in reverse chronological order

38

SEARCH

39

40

SEARCH

• by string: the user can specify if the system should search by exact match, beginning with, contains or fuzzy

• by URI or term code; or by range of term code (e.g. between 123 and 9876)

• by classification schemes

• by creation or modification date

• by specific relationships (e.g. search all concepts using the “has_pest”)

• by status, language

• by notes/attributes

41

SEARCH CRITERIA• Exact match (“water” will find only water)

• Starting with (“water” will find “water”, “water management”, and “watergate”)

• Contain (“water” will find “water”, “water management”, “inland water”, and “watergate”)

• Exact word (“water” will find “water”, “water management”, “inland water” but not “watergate”)

• Case Sensitive (“ABc” will find only for the word “ABc” and not “abc”

• Include Description

– Search also content of definitions, images, editorial notes, scope notes

• Include Spelling Variant

– Search also on different spelling variants

42

CONCEPT MANAGEMENT• Visualize / Navigate Concepts

– depending on the access level, user can edit

• Show selected concept details

– all terms and other information

• Show selected concept relationships

• Delete concept

• Can view the URI of the concept enabling ‘Show URI’ option

CONCEPT MANAGEMENT

43

ADD/DELETE CONCEPT

• Add term to the newly created concept in one language• Can delete the concept and all the relationship associated with that concept

44

45

CONCEPT RELATIONSHIP

• Can create the concept-concept relationship• Inverse relationship is also created

automatically– Ex: If we create A affect B, then B is affected by A

relationship is also created

CONCEPT IMAGE

• Name of the image with description

• URL will point to the image which will open in an external

• Provide the source of the image

• Can add more translation in different language

46

SCOPE/EDITORIAL NOTES• In Editorial Notes, we can post the modifications

made to the selected concepts• In Scope Notes, we can post information for indexing• Both can contain multiple values in multiple

languages

47

CONCEPT DEFINITION• Add definition to the selected concept • Add translation in different languages• Provide the source of the definition• Creation and modified date are set automatically

48

49

TERM MANAGEMENT

• Visualize / Navigate Terms – depending on the user access level and role

• Show selected term details• Show selected term relationships• Show term variances• Add/Edit/Delete term

ADD/EDIT/DELETE TERM• Term actions will be associated to the selected concept • Term can be created in different languages• Term can be set as preferred or non preferred• An option allows preferred terms visualization only in the concept tree

RELATIONSHIP MANAGEMENT

52

LABEL/DEFINITION

• Can add/edit/delete the label for relationship in multiple languages

• Can add/edit/delete definition of the relationships in multiple languages

53

PROPERTIES/ DOMAIN & RANGE

Can assign functional, transitive, inverse & symmetric properties to the selected relationship

Only functional properties can be selected for data type properties

Can specify the domain & range

54

VALIDATION

• Allows to verify the new concept/term/definition/relationships/notes/attributes created, edited or deleted.

55

56

57

EXPORT

CLASSIFICATION SCHEMES

• Add/Edit/Delete different classification schemes

• Can create new category or assign existing domain concept to the classification schemes

• Mapping categories to domain concepts is possible

58

USER MANAGEMENT

• Manages user detail information.• Assign each user different group privilege and languages.

59

GROUP MANAGEMENT

• Manages different groups, their permission and members.• Assign allowed actions for each group.

60

• Checks if there is any inconsistency in the model data.

61

SYSTEM PREFERENCES

• Manage user information/preferences• VocBench interface

62

63

RSS

• All the changes on the VocBench content is published through RSS.

• Helps people who regularly use VocBench to stay informed about the changes.

• Shows

– all the concept/terms/relationships created/edited/deleted

– Users/Groups created/edited/deleted

WEB SERVICES

• AGROVOC Concept Server is accessible via web services, which can be called from any client application.

• The web services are realized on Apache Axis running on Tomcat.

• Using web services, –helps third party application for easy access to WB content–changes on the content of AGROVOC Concept Server can be

accessed immediately–reduces the time and effort necessary to download and

incorporate the latest version of the AGROVOC Concept Server content into applications

SYSTEM OVERVIEW• Front End

– GWT/GWT Incubator• Google Web Toolkit

– Graph Visualization• Java Applet

• Middle ware– Service wrapper layer

• separates client and service layer• allows to switch between old Protégé implementation and Semantic Turkey

– Semantic Turkey/OWL Art API– Gilead

• integrating GWT and Hibernate

• Back end– Administrative DB : MySQL– Triple Store: Sesame/Jena/Allegrograph,..

72

Semantic Turkey/OWLArt API• Semantic Turkey provides

– business logic including OWL and SKOS support, – import for OWL and SKOS, – triple-store agnostic design and – an OSGi-compliant plug-in architecture.

• Semantic Turkey uses the OWLArt API which is already partially integrated within VocBench.

• OWLArt API offers– a basic RDF triple query and SPARQL access layer, which need to be

implemented for any specific triple store– methods more closely connected with operations related to the standard

vocabularies of the RDF family (from RDF to RDFS, OWL, SKOS and SKOS-XL).
