CoherenceEvaluator

Remarks

CoherenceEvaluator returns a NumericMetric that contains a score for 'Coherence'. The score is a number between 1 and 5, with 1 indicating a poor score, and 5 indicating an excellent score.

Constructors

CoherenceEvaluator()

Properties

ChatOptions	Gets the ChatOptions that this IEvaluator uses when performing evaluations. (Inherited from SingleNumericMetricEvaluator)
CoherenceMetricName	Gets the Name of the NumericMetric returned by CoherenceEvaluator.
EvaluationMetricNames	Gets the Names of the EvaluationMetrics produced by this IEvaluator. (Inherited from SingleNumericMetricEvaluator)
IgnoresHistory	Gets a value indicating whether this IEvaluator considers the entire conversation history (in addition to the request and response being evaluated) as part of the evaluation it performs. (Inherited from ChatConversationEvaluator)
MetricName	Gets the Name of the NumericMetric produced by this IEvaluator. (Inherited from SingleNumericMetricEvaluator)
SystemPrompt	Gets the system prompt that this IEvaluator uses when performing evaluations. (Inherited from SingleNumericMetricEvaluator)

Methods

CanRenderAsync(ChatMessage, Int32, ChatConfiguration, CancellationToken)	Determines if there is sufficient `tokenBudget` remaining to render the supplied `message` as part of the evaluation prompt that this IEvaluator uses. (Inherited from ChatConversationEvaluator)
EvaluateAsync(IEnumerable<ChatMessage>, ChatMessage, ChatConfiguration, IEnumerable<EvaluationContext>, CancellationToken)	Evaluates the supplied `modelResponse` and returns an EvaluationResult containing one or more EvaluationMetrics. (Inherited from ChatConversationEvaluator)
InitializeResult()	Returns an EvaluationResult that includes default values for all the EvaluationMetrics supported by this IEvaluator. (Inherited from SingleNumericMetricEvaluator)
ParseEvaluationResponseAsync(String, EvaluationResult, ChatConfiguration, CancellationToken)	Parses the evaluation result present in `modelResponseForEvaluationPrompt` into the EvaluationMetrics present in the supplied `result`. (Inherited from SingleNumericMetricEvaluator)
RenderAsync(ChatMessage, CancellationToken)	Renders the supplied `message` to a string that can be included as part of the evaluation prompt that this IEvaluator uses. (Inherited from ChatConversationEvaluator)
RenderEvaluationPromptAsync(ChatMessage, ChatMessage, IEnumerable<ChatMessage>, IEnumerable<EvaluationContext>, CancellationToken)	Renders the information present in the supplied parameters into a prompt that this IEvaluator uses to perform the evaluation. (Inherited from ChatConversationEvaluator)

Extension Methods

EvaluateAsync(IEvaluator, ChatMessage, ChatMessage, ChatConfiguration, IEnumerable<EvaluationContext>, CancellationToken)	Evaluates the supplied `modelResponse` and returns an EvaluationResult containing one or more EvaluationMetrics.
EvaluateAsync(IEvaluator, ChatMessage, ChatConfiguration, IEnumerable<EvaluationContext>, CancellationToken)	Evaluates the supplied `modelResponse` and returns an EvaluationResult containing one or more EvaluationMetrics.
EvaluateAsync(IEvaluator, String, ChatConfiguration, IEnumerable<EvaluationContext>, CancellationToken)	Evaluates the supplied `modelResponse` and returns an EvaluationResult containing one or more EvaluationMetrics.
EvaluateAsync(IEvaluator, String, String, ChatConfiguration, IEnumerable<EvaluationContext>, CancellationToken)	Evaluates the supplied `modelResponse` and returns an EvaluationResult containing one or more EvaluationMetrics.
