LlamaIndex is a simple, flexible data framework for connecting custom data sources to large language models (LLMs).

Large language models (LLMs) have demonstrated impressive reasoning abilities in complex tasks. However, they lack up-to-date knowledge and experience hallucinations during reasoning, which can...

LinkML is a language for modeling linked data

I spoke with Juan Sequeda about knowledge graphs and how he's leveraging them in the product at data.world - he also spoke about some of the new features tha...

Copyright 2024. Kurt Cagle / The Cagle Report A lot of the chatter lately in the machine learning community is beginning to shift towards discussions about semantics, and whether or not machines can actually "understand" them in any meaningful sense.

Learn how graph and vector search systems can work together to improve retrieval-augmented generation (RAG) systems.

Knowledge Graph (KG) inductive reasoning, which aims to infer missing facts from new KGs that are not seen during training, has been widely adopted in various applications. One critical challenge...

Wow, what a great farm-to-fork notebook by Jerry Liu that goes from 1) the exciting text of the San Francisco 2023 Budget Proposal (gnarly PDF!) all the way…

Using large language models to discern commonsense relationships can improve performance on downstream tasks by as much as 60%.

This week, I thoroughly enjoyed attending the 21st Extended #SemanticWeb Conference! Here’s a summary of the contributions presented at the conference about…

How SP used Ontotext GraphDB’s vector capabilities to build a simple RAG retriever over a Knowledge Graph, using open, offline LLM models

How we used Ontotext GraphDB’s vector capabilities to build a simple RAG retriever over a Knowledge Graph, using open, offline LLM models

At Semantic Partners, we wanted to build our informed opinion over the strengths and weaknesses of graph RAG for RDF triple stores. We considered a simple use case: matching a job opening with Curriculum Vitae. We show how we used Ontotext GraphDB to build a simple graph RAG retriever using open, offline LLM models – the graph acting like a domain expert for improving search accuracy.

Knowledge Graphs (KGs) represent human-crafted factual knowledge in the form of triplets (head, relation, tail), which collectively form a graph. Question Answering over KGs (KGQA) is the task of...

This specification defines an approach to represent generic forms of composite values (lists and maps, in particular) as literals in RDF, and corresponding extensions of the SPARQL language. These extensions include an aggregation function to produce such composite values, functions to operate on such composite values in expressions, and a new operator to transform such composite values into their individual components.

RDF combines universal ways to name, structure and give meaning to data using only open standards. Naming is done with URIs; the structure is always the subject-predicate-object triple, and the meaning is provided by extending RDF with shared vocabularies. These three ways, individually and in combination, enable autonomy and cohesion. Let's see how.

In this presentation, Hedden describes the components of an enterprise knowledge graph and provides further insight into the semantic layer.

When building GraphRAG, you may want to explicitly define the graph yourself, or use the LLM automatically extract the graph. Both have tradeoffs: the former… | 17 comments on LinkedIn

Over the past few weeks I’ve been researching, and building a framework that combines the power of Large Language Models for text parsing and transformation with the precision of structur…

A new benchmark for natural language questions against databases dropped last week. What does it mean and how does the dbt Semantic Layer stack up?

Here are my slides from KGC 2024: https://lnkd.in/gAhMRE_U. In a nutshell, I made the point that when it comes to adding advanced features to property graphs…
