HasSemanticModel()

Upgrades text similarity from lexical bag-of-words to true MEANING via a runtime neural model (load one process-wide with StzNeuralModelQ(path)). With no model loaded these degrade gracefully to the lexical path, so code keeps working and auto-improves once a model is present. TRUE if a runtime embedding model is loaded and ready.

also written: IsSemanticModelReady

Basic examples (1)

Softanza
o = new stzText("The cat sits on the mat")
# no model loaded here
? o.HasSemanticModel()
# Embedding() is empty without a model
? len(o.Embedding())
# SemanticSimilarityWith falls back to a lexical score in [-1,1]
? o.SemanticSimilarityWith("A kitten rests on the rug") >= 0
# identical text is maximally similar (lexical)
? o.SemanticSimilarityWith("The cat sits on the mat") > 0.99
# a non-string comparand is rejected
? o.SemanticSimilarityWith(123)
# IsSemanticallySimilarTo respects the threshold
? o.IsSemanticallySimilarTo("The cat sits on the mat", 0.5)

The extensions of this method

Each extension, and whether it exists for this method; an extension that exists combines with the others (FindSTCS).

Extension
Exists
What it adds · The names
Q
no
does what the method does, then returns the object, so the call can be chained
QQ
no
chains on the next, more specific type of object (the Q ladder)
QQQ
no
chains on the most specific type of object (the Q ladder)
QRT
no
returns the result as an object of the requested type
CS
no
takes a case-sensitivity flag
ST
no
takes the position to start from (StartingAt)
IB
no
takes bounds that are included (IncludingBounds)
XT
no
the extended form: more parameters than the base method
XTT
no
yet another extension: a further extended form, after XT
Z
no
includes the position in what it returns
ZZ
no
returns positions as sections, [start, end]
W
no
selects by a condition
WF
no
selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)
D
no
takes a direction, forward or backward (Directional)
F
no
takes a function (the condition or the update is given as a function); the forms document also uses F for the future form, which defers the action
Many
no
works on a collection of items instead of one (the plural form)
Except
no
takes exceptions, what to leave out (the exceptional form)
U
no
returns the result without duplication

Every example is a test file of the library, run inside the library for this page; only those whose output kept every promise their file wrote are shown.
