📚 In recent years, several specifications have emerged to define data assets managed as products. Today, two main types of specifications exist: 1️⃣ 𝗗𝗮𝘁𝗮 𝗖𝗼𝗻𝘁𝗿𝗮𝗰𝘁 𝗦𝗽𝗲𝗰𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻 (𝗗𝗖𝗦): Focused on describing the data asset and its associated metadata. 2️⃣ 𝗗𝗮𝘁𝗮 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗦𝗽𝗲𝗰𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻 (𝗗𝗣𝗦): Focused on describing the data product that manages and exposes the data asset. 👉 The 𝗢𝗽𝗲𝗻 𝗗𝗮𝘁𝗮 𝗖𝗼𝗻𝘁𝗿𝗮𝗰𝘁 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱 (𝗢𝗗𝗖𝗦) by Bitol is an example of the first specification type, while the 𝗗𝗮𝘁𝗮 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗼𝗿 𝗦𝗽𝗲𝗰𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻 (𝗗𝗣𝗗𝗦) by the Open Data Mesh Initiative represents the second. 🤔 But what are the key differences between these two approaches? Where do they overlap, and how can they complement each other? More broadly, are they friends, enemies, or frenemies? 🔎 I explored these questions in my latest blog post. The image below might give away some spoilers, but if you're curious about the full reasoning, read the post. ❤️ I'd love to hear your thoughts! #TheDataJoy #DataContracts #DataProducts #DataGovernance | 29 comments on LinkedIn

LLMs that automatically fill knowledge gaps - too good to be true? Large Language Models (LLMs) often stumble in logical tasks due to hallucinations, especially when relying on incomplete Knowledge Graphs (KGs). Current methods naively trust KGs as exhaustive truth sources - a flawed assumption in real-world domains like healthcare or finance where gaps persist. SymAgent is a new framework that approaches this problem by making KGs active collaborators, not passive databases. Its dual-module design combines symbolic logic with neural flexibility: 1. Agent-Planner extracts implicit rules from KGs (e.g., "If drug X interacts with Y, avoid co-prescription") to decompose complex questions into structured steps. 2. Agent-Executor dynamically pulls external data when KG triples are missing, bypassing the "static repository" limitation. Perhaps most impressively, SymAgent’s self-learning observes failed reasoning paths to iteratively refine its strategy and flag missing KG connections - achieving 20-30% accuracy gains over raw LLMs. Equipped with SymAgent, even 7B models rival their much larger counterparts by leveraging this closed-loop system. It would be great if LLMs were able to autonomously curate knowledge and adapt to domain shifts without costly retraining. But are we there yet? Are hybrid architectures like SymAgent the future? ↓ Liked this post? Join my newsletter with 50k+ readers that breaks down all you need to know about the latest LLM research: llmwatch.com 💡
