This system permits for speedy, domain-specific customization with out the desire for resource-intensive retraining processes. For duties reminiscent of assembly summarization and motion merchandise extraction, steered engineering permits actual keep an eye on over the generated outputs, ensuring they meet particular industry necessities. It permits for the versatile adjustment of activates to fit evolving use instances, making it a great resolution for dynamic environments the place type behaviors want to be briefly reoriented with out the overhead of type fine-tuning.
Amazon Nova fashions and Amazon Bedrock
Amazon Nova models, unveiled at AWS re:Invent in December 2024, are constructed to ship frontier intelligence at industry-leading worth functionality. They’re a few of the quickest and maximum cost-effective fashions of their respective intelligence tiers, and are optimized to energy undertaking generative AI packages in a competent, protected, and cost-effective way.
The figuring out type circle of relatives has 4 tiers of fashions: Nova Micro (text-only, ultra-efficient for edge use), Nova Lite (multimodal, balanced for versatility), Nova Professional (multimodal, steadiness of pace and intelligence, splendid for many undertaking wishes) and Nova Premier (multimodal, probably the most succesful Nova type for advanced duties and instructor for type distillation). Amazon Nova fashions can be utilized for numerous duties, from summarization to structured textual content technology. With Amazon Bedrock Model Distillation, consumers too can carry the intelligence of Nova Premier to a sooner and less expensive type reminiscent of Nova Professional or Nova Lite for his or her use case or area. This may also be accomplished during the Amazon Bedrock console and APIs such because the Converse API and Invoke API.
Answer review
This submit demonstrates methods to use Amazon Nova figuring out fashions, to be had via Amazon Bedrock, for computerized perception extraction the usage of steered engineering. We focal point on two key outputs:
- Assembly summarization – A high-level abstractive abstract that distills key dialogue issues, choices made, and significant updates from the assembly transcript
- Motion pieces – A structured listing of actionable duties derived from the assembly dialog that practice to all the crew or undertaking
The next diagram illustrates the answer workflow.

Answer elements
We advanced the 2 core options of the answer—assembly summarization and motion merchandise extraction—through the usage of well-liked fashions to be had via Amazon Bedrock. Within the following sections, we have a look at the activates that had been used for those key duties.
For the assembly summarization process, we used a persona assignment, prompting the LLM to generate a abstract in
For the motion merchandise extraction process, we gave particular directions on producing motion pieces within the activates and used chain-of-thought to toughen the standard of the generated motion pieces. Within the assistant message, the prefix
Other type households reply to the similar activates in a different way, and it’s essential to observe the prompting information explained for the precise type. For more info on perfect practices for Amazon Nova prompting, confer with Prompting best practices for Amazon Nova understanding models.
Dataset
To judge the answer, we used the samples for the general public QMSum dataset. The QMSum dataset is a benchmark for assembly summarization, that includes English language transcripts from educational, industry, and governance discussions with manually annotated summaries. It evaluates LLMs on producing structured, coherent summaries from advanced and multi-speaker conversations, making it a precious useful resource for abstractive summarization and discourse figuring out. For trying out, we used 30 randomly sampled conferences from the QMSum dataset. Each and every assembly contained 2–5 topic-wise transcripts and contained roughly 8,600 tokens for every transcript in reasonable.
Analysis framework
Attaining high quality outputs from LLMs in assembly summarization and motion merchandise extraction generally is a difficult process. Conventional analysis metrics reminiscent of ROUGE, BLEU, and METEOR focal point on surface-level similarity between generated textual content and reference summaries, however they incessantly fail to seize nuances reminiscent of factual correctness, coherence, and actionability. Human analysis is the gold usual however is costly, time-consuming, and no longer scalable. To handle those demanding situations, you’ll be able to use LLM-as-a-judge, the place any other LLM is used to systematically assess the standard of generated outputs in accordance with well-defined standards. This way provides a scalable and cost-effective solution to automate analysis whilst keeping up excessive accuracy. On this instance, we used Anthropic’s Claude 3.5 Sonnet v1 because the choose type as a result of we discovered it to be maximum aligned with human judgment. We used the LLM choose to attain the generated responses on 3 primary metrics: faithfulness, summarization, and query answering (QA).
The faithfulness rating measures the faithfulness of a generated abstract through measuring the portion of the parsed statements in a abstract which are supported through given context (for instance, a gathering transcript) with recognize to the overall selection of statements.
The summarization rating is the combo of the QA rating and the conciseness rating with the similar weight (0.5). The QA rating measures the protection of a generated abstract from a gathering transcript. It first generates a listing of query and solution pairs from a gathering transcript and measures the portion of the questions which are requested accurately when the abstract is used as a context as an alternative of a gathering transcript. The QA rating is complimentary to the faithfulness rating for the reason that faithfulness rating doesn’t measure the protection of a generated abstract. We solely used the QA rating to measure the standard of a generated abstract for the reason that motion pieces aren’t meant to hide all sides of a gathering transcript. The conciseness rating measures the ratio of the duration of a generated abstract divided through the duration of the overall assembly transcript.
We used a changed model of the faithfulness rating and the summarization rating that had a lot decrease latency than the unique implementation.
Effects
Our analysis of Amazon Nova fashions throughout assembly summarization and motion merchandise extraction duties published transparent performance-latency patterns. For summarization, Nova Premier accomplished the very best faithfulness rating (1.0) with a processing time of five.34s, whilst Nova Professional delivered 0.94 faithfulness in 2.9s. The smaller Nova Lite and Nova Micro fashions equipped faithfulness ratings of 0.86 and nil.83 respectively, with sooner processing occasions of two.13s and 1.52s. In motion merchandise extraction, Nova Premier once more led in faithfulness (0.83) with 4.94s processing time, adopted through Nova Professional (0.8 faithfulness, 2.03s). Curiously, Nova Micro (0.7 faithfulness, 1.43s) outperformed Nova Lite (0.63 faithfulness, 1.53s) on this specific process regardless of its smaller dimension. Those measurements supply precious insights into the performance-speed traits around the Amazon Nova type circle of relatives for text-processing packages. The next graphs display those effects. The next screenshot presentations a pattern output for our summarization process, together with the LLM-generated assembly abstract and a listing of motion pieces.
