Ontology Library

Ontology Management

Ontology Management consist of categorizing ontology, importing ontologies, showing imported ontology pool, seaching ontology and hierarchical Ontology class and property.

import Ontology

• User can import ontology files from web and local harddrive which collect already from anywhere.
• The way of importing ontologies are single URL, multiple URLs, single local file, multiple local files.
• Multiple local files importing is the way that user can select multiple from user local owl files.
• When Add button pressed, local file selection dialog box show up and selected to list the ontologies to upload COMET server.
  

• When Import button pressed, importing ontologies are processed with showing processing bar.

• The single URL importing is the way of importing ontology whose URL is known.
• After filling in the URL of ontology to import to the URL filed and Local Name of imported ontology and commets to describe the ontology, press import button to upload from web.

• All the imported ontologies to COMET server are listed in the Ontologies tab.
• This also show the first version of an ontology and ontology class hierarchy, property hierarchy when version information is double clicked in the ontology versions browser.

ontologies pool and versions browser

• The ontology file information can be shown with ontology verstion browser with clicking mouse right button to the version information.
• The ontology file information show the triples of ontology, class count, property counts and ontology file size.

setting ontology metadata

• When Show Metadata selection button is pressed, the selected ontology is tagged with metadata which is Dublin core or SKOS (Simple Knowledge Organization Systems).
• This metadata is used for user to find ontology with criteria.

searching ontology

• The other tab of Ontology is search ontology which is finding from ontology pool to find ontologies with several criterials.
• Searching criteria have 2 way which are Metadata and Property.
• If there are ontologies that meet criterias, all the ontologies are listed in the search ontology result browser.
• Ther searched ontologies are able to show class hierarchy, and property hierarchy to do double clicking on the ontology version browser item.
• The selected ontology version browser item can be attached to category.
• Edit Criteria button is able to edit already set criteria
• Delete Criteria button is able to delete the selected criteria in the search ontology by following criteria list.
• After Search button pressed, ontologies are searched by criteria which is set.

Search by Metadata criteria

• To find ontologies with criteria, press Add Criteria button and select Metadata selection.
• Metadata selection are Dublin core and SKOS (Simple Knowledge Organization Systems which have been tagged already.

Search by property criteria

• Property Criteria is about to Ontology components which are class, property, comment, and Lable.
• Class property is to find the onotology which include that ontology class local name.
• Property property is to find the ontology which include that ontology property local name.
• Comment property is to find the ontology which match rdfs:comment.
• Label property is to find the ontology which match rdf:label.

Ontology Class / Property Hierarchy

• The imported ontology class hierarchy is able to retrieved by ontology versions browser for the comparision to another version of same ontology.
• If user change the ontology with editor of COMET, user can compare the difference of classes which are added or deleted or modified.

 

• ontology property hierarchy is also able to retrived the same as ontology class hierarchy.

Ontology category

• Even though ontologies are collected from anywhere into ontology pool, user cant identify what the onotology is for.
• User can categorized collected ontology with System categories and My categories as the meaning of ontology
• System categories is managed by administrator of COMET server to show the standard category of collected ontologies.
• My categories is managed by the user who have account for COMET server.
• Category is able to attatch ontology from ontology pool and category as a subcategory.

Create / Edit / Delete category

• User create category from root category named System or My category by clicking right mouse button to select create System/My category.
• After created a category, the category can be drag and drop to another category to be subcategory.
• Edit category is to change the name of category.
• Delete category is to delete the category including all the subcategories.
• Statistics is the information of category which contain the count of attached onotology and category.

Attach / Detach ontology

• Ontologies are able to attach to a category which gather the related ontologies from ontology browser.
• When ontology version item are selected from ontology versions browser, drag and drop to the proper category to attach ontology.
• When detaching ontology, select ontology from attached to category and press menu detech ontology.
• The attached ontology act as ontology browser items that show the class hierarchy and property hierarchy when version browser item is double clicked.

delete ontology

• To delete ontology from ontology pool, the ontology to be deleted should be attached a category and pressed delete ontology button.
• The deleted ontology is disappeared from ontology pool and the related functions which use the deleted onotolgy dont work properly.

Ontology Engineering

Editing ontology

• From ontology pool, selected ontology can be edited through protege by pressing open image button which located right side of COMET label on the tool bar.
• Open button change the COMET client into editing mode with loading selected ontology.
• After editing ontololgy such as adding, deleteing class and property, user should save the ontology to change version and set the comment of changing by pressing save button that is floppy disket image.

Cancelation ontology edit

• The process of editing ontology are quited without saving by pressing X image button.

Saving edited ontology

• After saving ontology edited, ontology versions browser show the new version item which show the difference of previous ontology.
• Manual Diffs is user description of difference to the previous ontology.
• Automatic Diffs is automatic information of difference of previous ontology that contains changing of triples, classes and property.
• The difference can be checked with double clicking the two versions to see class hierarchy.

Query Management

• User can send SPARQL queries with an ontology through several query engine and reasoning engine.
• Query Management is consisted with System query and My Query tabs.
• Each Tab contain Query Library that is history of query saved with SPARQL representation and description of query.
• User can add, delete, edit from query library.

System / My Query

• System query is used to set standard query by administrator
• My Query is used for login user to test users own ontology.

Finding Legacy Query

• If there are many queries in the list, user can search queries with the keyword by SPARQL representation and description.

Describing SPARQL Query

• To write SPARQL, press add prefix button to set an ontology to be quried.
• Add prefix show the category where ontology is, the ontology to be selected, version of ontology to be quried.
• After setting the prefix, press ok button then Query prefix list will be listed.
• The Query prefix can be edited or deleted by Edit prefix and Delete prefix button.
• To the Query SPARQL representation. fill the SPARQL query in the field and describe the query meaning.
• Press save Query button to save and this saved query will be listed in the query library.
• Back button is to return query library.

Running Query

• After seting the query, user can select query engines which is listed in the combo box.
• Query engines is Sesame, Pellet, JENA_Pellet, JENA_ARQ and another Query/Reasoning Engine of third party.
• After selecting query engine, the result of query will be shown in the Query Execution Result table by the pressing Run button.
• The execution of query will be counted by Server and be reported.

Feedback

• If there are comments to inform us about COMET, send your comments to comet@saltlux.com

Caution

• There would be found some cautions of COMET client for the reason of Protege.

importing ontologies of prefix

• There are some ontologies that cant import ontologies which is used for prefix of.
• The message show up to be imported the ontology used for prefix.
• User is supposed to be get the ontology message said. If it is ignored, ontology editing result will not be reflected.
