respondrelated

Respondrelated refers to a capability in conversational systems to generate or retrieve responses that are semantically related to a given prompt, topic, or user intent. It is not a fixed response, but a class of methods to ensure relevance.

The typical pipeline includes analyzing input to extract topic or intent, selecting candidate responses from a knowledge base or a generative model, computing a relatedness score between candidates and the input, ranking, filtering for safety and policy, then delivering the top result.

Methods include embedding-based similarity using contextual embeddings, transformer-based ranking models, retrieval-augmented generation, or rule-based mappings. Some systems combine retrieval with generative generation to maintain factuality while remaining relevant.

Applications include customer support chatbots suggesting related articles, tutoring systems offering related explanations, virtual assistants providing follow-up topics, and search assistants surfacing related answers alongside direct results.

Evaluation focuses on relevance, coherence, usefulness, and safety, often using both automated metrics and human judgments. Limitations include potential for redundancy, bias, or hallucination, and the need for up-to-date knowledge.
