Classify()

Classify this text against ARBITRARY candidate labels with no training: rank each label by how closely its MEANING matches the text (embedding cosine when a model is loaded, else lexical). Pass richer label strings (e.g. "about sports") for sharper separation. Classify(labels) -- ranked [label, score] pairs, most similar first (DATA).

t = new stzText("the stock market prices fell sharply on wall street today")
# ClassifiedAs picks the closest label
? t.ClassifiedAs([ "market finance", "cooking food" ])
# Classify returns ranked [label, score] pairs, best first
? t.Classify([ "market finance", "cooking food" ])[1][1]
# Classify keeps all labels
? len(t.Classify([ "market finance", "cooking food", "space travel" ]))
# ClassifyQ is the basic stzList
? classname(t.ClassifyQ([ "a", "b" ]))
# ClassifyQQ is stzListOfPairs
? classname(t.ClassifyQQ([ "a", "b" ]))
# a non-list of labels is rejected
? @@(t.Classify("not a list"))

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
yes
does what the method does, then returns the object, so the call can be chained · ClassifyQ
QQ
yes
chains on the next, more specific type of object (the Q ladder) · ClassifyQQ
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.
