Reference documentation and code samples for the Discovery Engine v1 API class CheckGroundingResponse.Types.Claim.
Text and citation info for a claim in the answer candidate.
public RepeatedField<int> CitationIndices { get; }
A list of indices (into 'cited_chunks') specifying the citations
associated with the claim. For instance [1,3,4] means that
cited_chunks[1], cited_chunks[3], cited_chunks[4] are the facts cited
supporting for the claim. A citation to a fact indicates that the claim
is supported by the fact.
Position indicating the end of the claim in the answer candidate,
exclusive, in bytes. Note that this is not measured in characters and,
therefore, must be rendered as such. For example, if the claim text
contains non-ASCII characters, the start and end positions vary when
measured in characters (programming-language-dependent) and when measured
in bytes (programming-language-independent).
Indicates that this claim required grounding check. When the system
decided this claim doesn't require attribution/grounding check, this
field will be set to false. In that case, no grounding check was done for
the claim and therefore
[citation_indices][google.cloud.discoveryengine.v1.CheckGroundingResponse.Claim.citation_indices]
should not be returned.
Confidence score for the claim in the answer candidate, in the range of
[0, 1]. This is set only when
CheckGroundingRequest.grounding_spec.enable_claim_level_score is true.
Position indicating the start of the claim in the answer candidate,
measured in bytes. Note that this is not measured in characters and,
therefore, must be rendered in the user interface keeping in mind that
some characters may take more than one byte. For example,
if the claim text contains non-ASCII characters, the start and end
positions vary when measured in characters
(programming-language-dependent) and when measured in bytes
(programming-language-independent).
