Labels

Event labels are succinct descriptive attributes attached to events that can help with granular data selection and feature engineering use cases.

All our events occur within a category. We also have labels that indicate the classification within a category. You can think of it as sub-category level information. Sports is a category in our system but if you want to know what type of sport an event is for that is indicated by labels (e.g. nfl, mls, nhl, nba, etc)

For example, within the Conferences category, knowing the subject(s) covered within the conference (science-and-technology, educational, automotive, etc.) may help you narrow down on events that are relevant to your business.

• Each event record has two separate label fields (phq_labels and the legacy labels field).

• All categories have the new phq_labels and should be used by default.

• Event labels can be searched by using thephq_labels parameter.

• Some labels which repeats the category name such as label: academic have been removed.

PHQ Labels

PHQ Labels are generated through newer Large Language Models (LLMs) and overall achieve a higher standard of specificity and relevance in highlighting an event's key themes when compared to legacy methods.

This field is named phq_labels.

PHQ Labels are available for the following categories:

• Concerts

• Conferences

• Expos

• Festivals

• Performing Arts

• Community

• Academic

• Airport-delays

• Daylight-savings

• Disasters

• Health-warnings

• Observances

• Politics

• Public-holidays

• Severe weather

• School-holidays

• Terror

• Sports

PHQ Label Values

PHQ Labels are constantly being improved and updated by our team and LLM models therefore we recommend using Get Event Counts to retrieve an up-to-date and relevant list of PHQ Labels and the count of events labeled with each, within your PredictHQ plan.

Here is an example, for Taylor Swift and Sabrina Carpenter at the Melbourne Cricket Ground in 2024 it has the following PHQ labels (pop, country, and rock) in the API response:

"phq_labels": [ { "label": "pop", "weight": 0.51 }, { "label": "country", "weight": 0.25 }, { "label": "rock", "weight": 0.25 }

You could also use Query Parameters to retrieve a list and the count of PHQ Labels that match your criteria, e.g. PHQ Labels associated with the sports category or PHQ Labels of events that will be taking place in a specific time and place. Here is an example:

import requests

response = requests.get(
    url="https://api.predicthq.com/v1/events/count",
    headers={
      "Authorization": "Bearer $ACCESS_TOKEN",
      "Accept": "application/json"
    },
    ## optional, get PHQ Labels and counts for sports category only
    # params={"category": "sports"}
)


# get PHQ Labels and the count of events having them from the response
phq_labels = response.json().get("phq_labels")

print(phq_labels)
# > {'basketball': 408197,'parade': 14327, ... }

You can also see a list of PHQ Labels in the "Labels" field on the Search Events page of the WebApp:

The "Labels" field in the WebApp Search Events Page contains a list of PHQ Labels

Labels (Legacy)

Legacy labels are still returned in order to preserve backward compatibility with existing user implementations.

This field is named labels.

Legacy labels are available for all event categories.
