KnowBuddy™ and the Linguist™

KnowBuddy is a collaborative tool for curating and disambiguating text into grammatical English. 

The Linguist clarifies the logical semantics of English to the point of producing knowledge suitable for artificial intelligence. 

You can learn a lot about English, semantics, and logic using KnowBuddy and the Linguist.

Once you register, you can use KnowBuddy in any of the following ways:

If you have problems launching the webstart applications, please see these installation and setup notes.


By launching the software, you agree to the terms of the Basic Web License.

Getting Started

When you launch, after providing your credentials, you will choose a knowledge base.  By default, everyone has access to the “public” knowledge base.  This knowledge base will shows a variety of sentences, fragments, and phrases organized within a lattice of groups.  Each of the sentences is typically “axiomatic”, meaning that someone has fully disambiguated it using KnowBuddy and even further disambiguated it logically using the Linguist.  You can learn a lot by opening these sentences (just double click on them) and learning what the various toolbar buttons and right and left clicks do.  Various articles on Automata, Inc’.s blog ( also discuss and demonstrate various capabilities of the software.

This page describes labels or tags that you may encounter:

This page describes how semantic discriminants are displayed in the “clauses” tabs of analysis forms

This page describes how KnowBuddy handles words that are not in its lexicon.

Unrecognized Words

If KnowBuddy encounters a word that is not in its lexicon (or that it does not understand as derived from a word in its lexicon), it will present the “Unknown Word” dialog if so configured in the settings (e.g., by default).

KnowBuddy vs. the Linguist

We recommend you master KnowBuddy before moving on to the Linguist, which can be launched using this link.  First, get comfortable using KnowBuddy for sentences under 10 words long.  If you are comfortable with sentences up to 20 words long, you are certainly ready for the Linguist.
