Matrix Views

Description

Several spreadsheet-style views of an ontology, including existential fillers, individual relationships and an object properties view.

Features

• Navigate by fully functioning class/property tree
• Add/remove columns to customize - show any combination of annotations/properties/features
• Comma-separate values in a list for quick editing
• Drag and drop object or data properties on the matrices to add columns
• Drag and drop classes on the matrices to add fillers, domains and ranges
• Filter annotation columns by language (to allow translation-style view)
• Filter property columns by restriction type (some or only supported)
• Full class expressions supported in editors

The plugins

Window | Tabs menu Two default tab layouts are provided:

Matrix

Property Matrix Window | Views menu All of the matrices are implemented as views so you can add them into your own custom tabs:

Class Views

• Class annotations

• Class matrix (asserted and inferred hierarchies) - previously Class Existential MAtrix

• For highly compositional ontologies a lot of time can be saved by using the Class Matrix to add multiple superclass restrictions on classes.

• Add property columns to the matrix, either by drag and drop or using the toolbar add object/data property column to matrix. - Dnd will default to some restrictions, but with the add button you can specify this.

• Some cells may already contain values. There can be several fillers in one cell. See below for the meaning of the highlighting.

• Add values by dragging classes onto the cell or edit by clicking in a cell to start a text editor.

• The column specifies the property and the restriction type.

if a cell value is

• plain - filler of a restriction in a subclass (can be edited)
• bold - filler of a restriction in an equivalent class (not affected by editing)
• (bracketed) - this means it is an inherited from an ancestor (not affected by editing)

Multiple values in cells are separated by commas and each value is a filler for a separate sub/equivalent class restriction.

Eg

p (some) q (only) SuperA ClassE --ClassA ClassB ClassC, ClassD (ClassE ClassF Then the ontology contains:

equivalentClass(ClassA, p some ClassB) actually p some ClassB may be in an intersection

subClassOf(ClassA, p some ClassC)

subClassOf(ClassA, p some ClassD)

subClassOf(SuperA, p some ClassE) shows up as inherited for all subs of SuperA

subClassOf(ClassA, q only ClassF)

Individual Views

• Class membership
• Property Assertions - previously Individual Relationships

Object Property Views

• Object property matrix
• Data Property Views
• Data property matrix

Quick Start

Translation

To aid multilingual label generation for entities, all matrix views allow filtering by language. To set up a view as below, follow these steps:

• Enable one of the matrix tabs or add a matrix view to a current tab
• Press the top left button on the menu bar Add annotation column to matrix. A dialog will appear.
• Select the annotation URI in which you will create your labels
• Select a language you will be adding labels for
• Press OK
• If you want to provide multiple translations or compare against an existing translation repeat from step 2, but select a different language
• Open up your hierarchy and select the first cell you wish to edit
• When entered, return drops to the next entity and you can start typing immediately
