# `tag` applies labels to data.

`tag` names every label that fits. Each label gets its own probability. A label counts when it clears the bar, and the default bar is 0.5.

## Run it

*At 0.5, Octopus's Garden gets three labels.*

```
is_a_song="The text is the title of a song by the Beatles."
question="$is_a_song Which of these describe it?"
labels=(
  "love song"
  sad
  psychedelic
  "about a place"
  "about the sea"
)

cat <<'EOF' |
Yesterday
Penny Lane
Octopus's Garden
EOF
thinkthen tag "$question" "${labels[@]}" \
  --batch 1 \
  --lines \
  --threshold 0.5 \
  --replay recording |
jq .
```

*Output*

```
{
  "input": "Yesterday",
  "value": [
    "love song",
    "sad"
  ]
}
{
  "input": "Penny Lane",
  "value": [
    "psychedelic",
    "about a place"
  ]
}
{
  "input": "Octopus's Garden",
  "value": [
    "psychedelic",
    "about a place",
    "about the sea"
  ]
}
```

*exit 0*

## Change the bar

*At 0.7, two songs lose psychedelic.*

```
is_a_song="The text is the title of a song by the Beatles."
question="$is_a_song Which of these describe it?"
labels=(
  "love song"
  sad
  psychedelic
  "about a place"
  "about the sea"
)

cat <<'EOF' |
Yesterday
Penny Lane
Octopus's Garden
EOF
thinkthen tag "$question" "${labels[@]}" \
  --batch 1 \
  --lines \
  --threshold 0.7 \
  --replay recording |
jq .
```

*Output*

```
{
  "input": "Yesterday",
  "value": [
    "love song",
    "sad"
  ]
}
{
  "input": "Penny Lane",
  "value": [
    "about a place"
  ]
}
{
  "input": "Octopus's Garden",
  "value": [
    "about a place",
    "about the sea"
  ]
}
```

*exit 0*

## The lesson

Penny Lane and Octopus's Garden are psychedelic at 0.5 and lose the label at 0.7. The bench has no answer key for tag.

A higher bar keeps fewer labels.
