    1. In a broader sense, taxonomy also applies to relationship schemes other than parent-child hierarchies, such as network structures. Taxonomies may then include a single child with multi-parents, for example, "Car" might appear with both parents "Vehicle" and "Steel Mechanisms"
    1. graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects

    1. David Benkeser. (2020, November 9). Another view on uncertainty associated based on Pfizer’s results. Even if you were highly skeptical about MRNA vaccines (many are [were?]) with 50% prior belief that VE ~ 0, based on an 8:86 vax:placebo case split, the posterior probability that VE > 75% is ~ 1.

    1. (((Howard Forman))). (2020, November 24). Truly good news out of #Italy. And we can all use it. Cases (23K), positive rate (12.3%), and hospitalizations all DOWN. ICU occupancy with smallest increase in months. Deaths (not surprisingly) the one exception with 3rd highest total.

    1. In fact, such small effectively closed scientific communities built on interpersonal relationships already exist to some extent

      so the weights in the reputation graph are personal knowledge, not citations or whatever.

    1. Usually while writing a Notion, I show the graph of how it connects to other Notions/Notes alongside it. I set the graph to show not only the 1st level links, as that only shows the links already apparent from the text I have in front of me. I set it to show 3 steps out at the start, and reduce to two steps when there are more links.

      This is a great idea that hasn't occurred to me before. When looking for non-obvious relationships between concepts (something that I think forms part of creativity), it makes sense to have the graph view open alongside the note you're working on.

    1. I've spent the last 3.5 years building a platform for "information applications". The key observation which prompted this was that hierarchical file systems didn't work well for organising information within an organisation.However, hierarchy itself is still incredibly valuable. People think in terms of hierarchies - it's just that they think in terms of multiple hierarchies and an item will almost always belong in more than one place in those hierarchies.If you allow users to describe items in the way which makes sense to them, and then search and browse by any of the terms they've used, then you've eliminated almost all the frustrations of a file system. In my experience of working with people building complex information applications, you need: * deep hierarchy for classifying things * shallow hierarchy for noting relationships (eg "parent company") * multi-values for every single field * controlled values (in our case by linking to other items wherever possible) Unfortunately, none of this stuff is done well by existing database systems. Which was annoying, because I had to write an object store.

      Impressed by this comment. It foreshadows what Roam would become:

      • People think in terms of items belonging to multiple hierarchies
      • If you allow users to describe items in a way that makes sense to them and allow them to search and browse by any of the terms they've used, you've solved many of the problems of existing file systems

      What you need to build a complex information system is:

      • Deep hierarchies for classifying things (overlapping hierarchies should be possible)
      • Shallow hierarchies for noting relationships (Roam does this with a flat structure)
      • Multi-values for every single field
      • Controlled values (e.g. linking to other items when possible)
    1. Knowledge graphs combine characteristics of several data management paradigms: Database, because the data can be explored via structured queries; Graph, because they can be analyzed as any other network data structure; Knowledge base, because they bear formal semantics, which can be used to interpret the data and infer new facts.

      Characteristics / benefits of a knowledge graph

    1. The ontology data model can be applied to a set of individual facts to create a knowledge graph – a collection of entities, where the types and the relationships between them are expressed by nodes and edges between these nodes, By describing the structure of the knowledge in a domain, the ontology sets the stage for the knowledge graph to capture the data in it.

      How ontologies and knowledge graphs relate.

    1. An ontology is as a formal, explicit specification of a sharedconceptualization that is characterized by high semantic ex-pressiveness required for increased complexity [9]. Ontolog-ical representations allow semantic modeling of knowledge,and are therefore commonly used as knowledge bases in artifi-cial intelligence (AI) applications, for example, in the contextof knowledge-based systems. Application of an ontology asknowledge base facilitates validation of semantic relationshipsand derivation of conclusions from known facts for inference(i.e., reasoning) [9]

      Definition of an ontology

    2. A knowledge graph acquires and integrates infor-mation into an ontology and applies a reasonerto derive new knowledge.

    1. Maybe your dbt models depend on source data tables that are populated by Stitch ingest, or by heavy transform jobs running in Spark. Maybe the tables your models build are depended on by analysts building reports in Mode, or ML engineers running experiments using Jupyter notebooks. Whether you’re a full-stack practitioner or a specialized platform team, you’ve probably felt the pain of trying to track dependencies across technologies and concerns. You need an orchestrator.Dagster lets you embed dbt into a wider orchestration graph.

      It can be common for [[data models]] to rely on other sources - where something like [[Dagster]] fits in - is allowing your dbt fit into a wider [[orchestration graph]]

    1. The needs: keyword enables executing jobs out-of-order, allowing you to implement a directed acyclic graph in your .gitlab-ci.yml. This lets you run some jobs without waiting for other ones, disregarding stage ordering so you can have multiple stages running concurrently.
    1. A spreadsheet may be represented as a directed acyclic graph, with each cell a vertex and an edge connected a cell when a formula references another cell. Other applications include scheduling, circuit design and Bayesian networks.
    1. the name of something and when you press the button to go to the link if it wasn't there it made the card

      This is a phenomenally important UX insight and affordance that has become a foundation of how all modern wiki-linking knowledge graph tools work today. Kudos to Ward for this!

    1. So Memex was first and foremost an extension of human memory and the associative movements that the mind makes through information: a mechanical analogue to an already mechanical model of memory. Bush transferred this idea into information management; Memex was distinct from traditional forms of indexing not so much in its mechanism or content, but in the way it organised information based on association. The design did not spring from the ether, however; the first Memex design incorporates the technical architecture of the Rapid Selector and the methodology of the Analyzer — the machines Bush was assembling at the time.

      How much further would Bush have gone if he had known about graph theory? He is describing a graph database with nodes and edges and a graphical model itself is the key to the memex.

    1. Ruby has some really nice libraries for working with linked data. These libraries allow you to work with the data in both a graph and resource-oriented fashion, allowing a developer to use the techniques that best suit his or her use cases and skills.
    2. Another Ruby gem, Spira, allows graph data to be used as model objects
