GumGum Contextual Data
JSON response data is maintained by Verity GumGum Contextual for a time-to-live (TTL) period. There are different TTL periods for Page, Video, Image, and Text content.
Pages are further analysed to differentiate between website home pages and all other pages on the site (as website home pages typically update frequently). For example, https://www.latimes.com/ (the home page of the Los Angeles Times) updates frequently, so Verity GumGum Contextual assigns a TTL of 30 minutes. The page https://www.latimes.com/travel/list/la-best-dog-friendly-hikes-trails-beaches-parks is unlikely to be updated frequently, so Verity GumGum Contextual assigns a longer TTL of 30 days.
Verity GumGum Contextual considers a home page to be a web page accessed at either:
<website URL>/
<website URL>/index.html
Content Type | Default TTL | |
|---|---|---|
Website home page | 30 minutes | |
All other pages | 30 days | |
360 days | ||
14 days | ||
30 days | ||
Every Verity GumGum Contextual response includes processedAt and expiresAt fields, indicating the date and time that classification data was generated and will expire from Verity GumGum Contextual storage:

"processedAt": "2021-05-25T17:57:03.690Z" "expiresAt": "2021-06-24T17:57:03.690Z" |
