<p>Shouldn’t it be possible since forever to put machine readable source information into PDF metadata. It’s more a problem of the tools and programs generating the PDFs.<p>We spend millions turning structured information into PDFs and billions to extract the same data from a printer rendering language</p>

<p>Thanks for the praise for APOC-ML, happy that it's useful.<p>Did you see the two blog posts that Tomaz Bratanic did on the topic?<p>For the ingestion: <a href="https://neo4j.com/developer-blog/global-graphrag-neo4j-langchain/" rel="nofollow">https://neo4j.com/developer-blog/global-graphrag-neo4j-langc...</a>
For the retrievers: <a href="https://neo4j.com/developer-blog/microsoft-graphrag-neo4j/" rel="nofollow">https://neo4j.com/developer-blog/microsoft-graphrag-neo4j/</a><p>My general point on GraphRAG is that it extracts and compresses the horizontal topic-clustering across many documents and makes that available for retrieval.<p>And that by creating the semantic network of entities, you can use patterns in the graph structure to answer questions that rely on information coming together from different documents. Think the detectives board connecting facts with strings from many different sources.<p>Feel free to ping me for a deeper discussion: michael at neo4j</p>

Basically algorithms from signal processing applied to huge volumes of historical and current data to determine buy and sell signals. Originally developed for national defense.<p>Very secretive all external partners were bought out. Only hundred or so people benefited in the billions per person.

<p>We always loved the snipped execution in TextMate that shows the results as a tooltip. Venkat Subramaniam used it in all his talks and demos.<p>Tried to find it as a VS Code extension, but there was nothing. So not knowing how to build one and being TypeScript noobs, we employed GPT-4 to build it  late night in a few hours. We called it "Venkat" in his honor.<p>And it turned out pretty well, so we're happy for you to try it out and let us know what you think (or rip it apart).</p>

<p>The article is factually incorrect on many fronts. There were only 3 reactors running at last. Nuclear was never profitable, the country shouldered most of its costs (esp for radioactive waste storage)<p>The renewable energy transition was blocked and delayed by the same Merkel govt. Germany was once leading in wind and PV energy and all those industries were destroyed and almost 100k jobs lost. 60bn subsidies per year go to fossil fuel companies including coal mining and burning. Often under the disguise of job retention. All through industrial lobbying and strong unions in the fossil fuel industries.</p>

<p>Not sure if you saw our graphql integration, that takes typedefs and converts a graphql query into a single cypher query, which can then be executed directly. <a href="https://neo4j.com/product/graphql-library/" rel="nofollow">https://neo4j.com/product/graphql-library/</a> has links to docs and api scaffolding tools.<p>When I started back then in 2016 with it, it was pretty cool how directly graphql mapped to the graph model in the db.</p>
