HOME - RECENT CHANGES Lists all the changes in reverse chronological order 12

SEARCH 13

14 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

15 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

16 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 17

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 18

19 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 20

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 21

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 22

23 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 browser 24

CONCEPT GRAPH VISUALIZATION 25

RELATIONSHIP MANAGEMENT 26

LABEL/DEFINITION Can add/edit/delete the label for relationship in multiple languages Can add/edit/delete definition of the relationships in multiple languages 27

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 28

VALIDATION Allows to verify the new concept/term/definition/relationships/notes/attribut es created, edited or deleted. 29

30 VALIDATION PROCESS GUEST Proposed by guest VALIDATOR Validated PUBLISHER Published TERM EDITOR Revised ADMINISTRATOR Published ONTOLOGY EDITOR Proposed deprecated PUBLISHER Deprecated

STATISTICS Provides statistical data on concepts terms users relationships 31

32 EXPORT Formats – SKOS – RDBMS-SQL – TBX – OWL

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 33

USER MANAGEMENT Manages user detail information. Assign each user different group privilege and languages. 34

GROUP MANAGEMENT Manages different groups, their permission and members. Assign allowed actions for each group. 35

CONSISTENCY CHECK Checks if there is any inconsistency in the model data. 36

SYSTEM PREFERENCES Manage user information/preferences VocBench interface 37

38 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

39 WEB SERVICES VocBench maintains access response uses SKOS Triple Store Other Applications

40 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

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). 51
