Basic samples

Basic samples seem intuitively simple but can be tricky to analyze. Compound sentences, adjectives, adverbs, and modals are difficult to identify, even for non-expert humans.

Let’s begin with an easy sample for the transformer.

Sample 1

The first sample is long but relatively easy for the transformer:

Did Bob really think he could prepare a meal for 50 people in only a few hours?

Run the Sample 1 cell in SRL.ipynb:

prediction=predictor.predict(
    sentence="Did Bob really think he could prepare a meal for 50 people in only a few hours?"
)
head(prediction)

BERT SRL identified the four predicates; the verb for each one labeled the result as shown in this excerpt using the head(prediction) function:

Verb: Did [V: Did] Bob really think he could prepare a meal for 50 people in only a few hours ?
Verb: think Did [ARG0: Bob] [ARGM-ADV: really] [V: think] [ARG1: he could prepare a meal for 50 people in only a few hours...
