Methods

#attributes

def attributes() -> ::Google::Protobuf::Map{::String => ::Google::Cloud::DiscoveryEngine::V1::CustomAttribute}
Returns
  • (::Google::Protobuf::Map{::String => ::Google::Cloud::DiscoveryEngine::V1::CustomAttribute}) — Extra user event features to include in the recommendation model. These attributes must NOT contain data that needs to be parsed or processed further, e.g. JSON or other encodings.

    If you provide custom attributes for ingested user events, also include them in the user events that you associate with prediction requests. Custom attribute formatting must be consistent between imported events and events provided with prediction requests. This lets the Discovery Engine API use those custom attributes when training models and serving predictions, which helps improve recommendation quality.

    This field needs to pass all below criteria, otherwise an INVALID_ARGUMENT error is returned:

    • The key must be a UTF-8 encoded string with a length limit of 5,000 characters.
    • For text attributes, at most 400 values are allowed. Empty values are not allowed. Each value must be a UTF-8 encoded string with a length limit of 256 characters.
    • For number attributes, at most 400 values are allowed.

    For product recommendations, an example of extra user information is traffic_channel, which is how a user arrives at the site. Users can arrive at the site by coming to the site directly, coming through Google search, or in other ways.

#attribution_token

def attribution_token() -> ::String
Returns
  • (::String) — Token to attribute an API response to user action(s) to trigger the event.

    This token enables us to accurately attribute page view or conversion completion back to the event and the particular predict response containing this clicked/purchased product. If user clicks on product K in the recommendation results, pass [RecommendResponse.attribution_token][] as a URL parameter to product K's page. When recording events on product K's page, log the [RecommendResponse.attribution_token][] to this field.

#user_pseudo_id

def user_pseudo_id() -> ::String
Returns
  • (::String) — Required. A unique identifier for tracking visitors.

    For example, this could be implemented with an HTTP cookie, which should be able to uniquely identify a visitor on a single device. This unique identifier should not change if the visitor log in/out of the website.

    Do not set the field to the same fixed ID for different users. This mixes the event history of those users together, which results in degraded model quality.

    The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.

    The field should not contain PII or user-data. We recommend to use Google Analytics Client ID for this field.
