Hi Linas,

Just wondering, is it possible to combine multiple words in right-star queries? I believe it would make the system equivalent to that GPT thing.

Sure. The GPT-thing uses skip-grams; the system here uses disjuncts aka "connector sets". The whole point is to extract grammatical structure.

Caution: The GPT thing is trained on billions of sentences, and requires petabytes of RAM, something I don't have. On the other hand, I suspect opencog/learn  is smaller and more accurate than GPT, but I cannot prove this. It's just a guess.

Anyway, visualizing disjuncts is a stepping stone. Let me show examples:

                  +---------Ost--------+
    +----->WV---->+  +------Ds**c------+       +----Js---+
    +-->Wd--+<SFst+  |      +----Am----+---Mf--+   +--Ds-+
    |       |     |  |      |          |       |   |     |
LEFT-WALL here  is.v a longer.a-c statement.n of some kind.n

Here are two incomplete sentences:

    +----->WV---->+  +------Ds**c------+       +->>> ???
    +-->Wd--+<SFst+  |      +----Am----+---Mf--+
    |       |     |  |      |          |       |
LEFT-WALL here  is.v a longer.a-c statement.n of

                  +------Ost---->>> ???
    +----->WV---->+  +----Ds**c-->>> ???
    +-->Wd--+<SFst+  |
    |       |     |  |    
LEFT-WALL here  is.v a

Here is a single disjunct:

    <<<------Ost--------+
       <<<---Ds**c------+                              
              <<<-Am----+---Mf-->>>
                        |    
                   statement.n    

Here is the Atomese for it:

(Section
    (Word "statement.n")
    (ConnectorSeq
         (Connector (Link "Ost") (Dir "-"))
         (Connector (Link "Ds**c") (Dir "-"))
         (Connector (Link "Am") (Dir "-"))
         (Connector (Link "Mf") (Dir "+"))))

This can be written as s string, much more compactly:

statement.n:  Ost- & Ds**c- & Am- & Mf+;

Amir has created a system where you can type in sentences with wild-cards, and it will auto-complete them for you. The above three examples would be:

"Here is a longer statement of * *"

"Here is a * * * * *"

"* * * * statement * * *"

You can put the holes anywhere: "here is a * statement of * *"  or "* * a longer statement * * kind"  and it will "fill in the blanks".

 

Anyway, now you understand why I am interested in visualizing the disjuncts and tracing around in them.
