Add wordnik-based synonyms and antonyms into the Dash via Unity Thesaurus scope

Access weather informations in a matter of seconds, perform mathematical calculations directly in the Dash, etc, are actions available via Unity Utilities lens, lens that houses and exposes informations as generated by various sources, while remaining hidden (without a dedicated icon on Dash's lens bar).

Adding a dictionary-like functionality to the Utilities lens can be easily achieved via the recently released Unity Dictionary scope, consequently, after installing the Dictionary scope, typing a word in Dash home's search area, displays numerous wordnik-based definitions (related to the typed word).

Unity Thesaurus scope enlarges the mentioned Dictionary range, providing Antonyms and Synonyms in the Dash home, thus presenting, along with the regular dictionary usefulness, handy linguistic bits.

A minor yet relevant aspect of the Thesaurus scope is its Dash positioning, meaning, typing a word in the search area, exposes its dictionary-specific details in the following order: Definitions, Synonyms and Antonyms (properly ordering the categories by a natural relevancy).

Synonyms and antonyms are directly displayed in their categories, allowing users to immediately "digest" the summoned results, without clicking on items and navigating to their wordnik webpage (latter approach suitable for more in-depth inquiries).

How do we install Unity Utilities lens (containing Unity Thesaurus scope and Unity Dictionary scope)?
Add the following official PPA (Precise)

sudo add-apt-repository ppa:scopes-packagers/ppa

sudo apt-get update
sudo apt-get install unity-lens-utilities unity-scope-dictionary unity-scope-thesaurus

then, restart the computer.
