Framework for Financial Reasoning (Brainstorming)

Inspired by the Framework for Legal Reasoning explained in the book Legal Informatics that is based on the paper ANGELIC II: An Improved Methodology for Representing Legal Domain Knowledge; I am going to create a Framework for Financial Reasoning using those techniques and see what I can get that system to do.

Systematic computational analysis of general purpose financial reports is a tool needed to work with such reports in the information age.

I am going to use the XBRL technical syntax to represent the rules. I am going to use the certainty factor model used by domains like medicine and legal.  This, from the link above, explains the certainty factor model:

The certainty-factor (CF) model is a method for managing uncertainty in rule-based systems for medicine and other domains that included the assumptions that faults or hypotheses were mutually exclusive and exhaustive, and pieces of evidence were conditionally independent, given each fault or hypothesis.

What this seems to do is enable a mixture of deductive reasoning and inductive reasoning.  Basically, "fuzzy logic".  But this may turn out to be a combination of what something like what LLMs and transformers can do combined with a knowledge graph.  Not sure of the relationship between LLMs/transformers and fuzzy logic.  They sort of seem to do similar sorts of things.

Relational Knowledge Graph System (RKGS)

Relational Knowledge Graph System (RKGS) is an interesting idea that combines the relational paradigm and the knowledge graph paradigm.  This documentation, Why RKGS , explains the idea. This gets even more interesting with the notion of "relational AI".  RelationalAI is described as follows by the company of the same name, Relational.ai : “RelationalAI is a cloud-based relational knowledge graph management system, with state of the art probabilistic processing and declarative reasoning at scale to make developing Data Applications a superpower for your business.” This notion of knowledge graphs represented in relational databases fits into my belief that knowledge graphs have two aspects: the expression SYNTAX and the logic of what is expressed or SEMANTICS. While the LOGIC of a knowledge graph is always the same regardless of technical syntax used to express that logic; there are many, many different technical syntaxes that can be used to represent a knowledge graph. There

Graph Hairball

Image
Knowledge graph system logic, the "things" and "relations between things" that  graph theory calls "vertices" (a.k.a. nodes, points, entities, things) and "edges" (a.k.a.  links, lines, relations, associations), looks like a big graph hairball as some people call it an example of which you can see here: Why?  This common view of a graph is because there has to be some "general view" of the information provided by the graph.  This is just like a general view of the information within a relational database is a table ; a set of ROWS and COLUMNS for exactly one table at a time. So what is interesting is that with a graph database the default view is everything in the graph of knowledge.  Whereas the default view of everything in a relational database is one table at a time. Further, it does not really matter whether the information that populates your knowledge graph comes from, say, CSV files, Excel, JSON, XBRL, RDF, PROLOG or whateve

PLATINUM Business Use Cases, Test Cases, Conformance Suite

A brick wall is made of exactly two things: bricks, mortar. But a brick wall created by a master craftsman, or mason, and a brick wall created by a “weekend warrior” with no knowledge of masonry will be very different. Master craftsmen are created and that process takes time and effort. This blog post is a first prototype that brings several things together into one useful resource for business professionals.  It pulls together the human readable information of the Showcase of Reports   and the machine readable information of the Conformance Suite of XBRL-based Financial Reports Prepared using the Seattle Method .  Then, I want to incorporate the information found in these PLATINUM XBRL-based Financial Report Examples . The three resources can be useful and used independently; but they are even more useful when used together.  Business professionals really could not care a less about the technical details of getting some result that they want.  But technical professionals need to under
