Conceptual Graphs inspired by John F Sowa.

Create Concept Graphs and Schemas, that can call functions and access databases to create answer graphs.

Best enjoyed with some white papers along side.

Theory straight from John F. Sowa's Paper titled Conceptual Graphs for a Data Base Interface July 1976 All credit for the Theory of Conceptual Graphs goes to Sowa amongst many other great minds before him, who believe in a better, more human-like computer interaction. We truly stand on the shoulders of giants.

Query Algorithm

Answer Graph Criterias to check for:

  1. w is a well formed CG
  2. w is true if the data base is correct
  3. The entire query graph q is covered by a join from w
  4. For every concept in q that has a value, the corresponding concept in w has the same value.
  5. For every concept in q that had a question mark, the corresponding concept in w has a value.

Algorithm A <Conceptual Graphs, pg.349>

  • Start with the concepts on the query graph that are flagged with question marks;
  • Join conceptual schemata to the graph so that the flagged concepts are covered by target concepts;
  • Propagate the question marks backwards along the function links;
  • Evaluate any functional dependencies whose source all have values;
  • Repeat until the original question is answered.

Algorithm B <Conceptual Graphs, pg.349>

  • Every join of a new schema to the developing answer graph must at least cover one of the concepts in the original query graph'

Algorithm C

  w: = q;
  while ( there is a preferred join j with w)  // seems to imply we have a list of joins
    do begin
      w: = result of performing j with w; //need function to do a join, also a score function
      while (there is a source conept a in w &&
            a does not have a value &&
            a does not have a question mark &&
            the target of a has a question mark)
        do place a question mark on a; //propagation
      while (there is a target concept b in w &&
             b has a question mark &&
             all sources of b have values)
        do get a value for b from it's access procedure (function); // reasoning
     if (there are no question marks left in w and all of q has been covered
         by some join)
         then begin:
          print answer; // result
          stop
          end
    end.

So as preparation of running a query through algorithm c we need to find possible joins and rank them per explanation in paper.

Given a set of possible joins s1 ... sn, score each graph by

  • One point for each concept in j that is the same as in w
  • One point per concept that is in q (original query)
  • If a question mark in w is covered by a target in j another point
  • If a question mark is covering a source concept subtract one point
  • If a concept in w, with a value is covered by source in a function link add a point, if it is covered by a target, reject j.
  • each concept or relation in q that has not been covered, if j covers it add a point each

Also need to consider a function that can return true if something is a subsort of a specific concept type.

Also indices for each type of concept or target or source links, if performance issues occur for searching the schematic universe.

prompting points (might not need this) are whenever it cannot find a join but a question mark remains on a quant('A')

The join function:

reference to concepts in common loop through join, giving you the concepts you want matching find concept person in graph2 find concept2 of join in graph1 and graph2 and merge them together

  • COI (Context of Interest)

Power Context Family

Situation / Propositions

Situations & Propositions are types of contexts.

Obligation vs. Permission vs. Prohibition

Forming the bases of contracts

Bayesian / Probabilistic Context?

Language Generation & Mapping

Utterance Paths

The sequence of nodes and arcs that are traversed in mapping a graph to a sentence is called the utterance path.

Marked Forms

For emphasis,however,most languages permit optional inversions,such as the following English sentence in OSV form:

"His new-found friend he took with him to the park."

Such forms, which break the normal pattern of the language, are marked forms as opposed to the normal, unemphatic, unmarked forms.

Marked Forms as HTML

It is possible to now describe relations accurately

Lexical Vector Representations from Concepts

Descriptions:

  • Concept: Unit of Knowledge
  • Term: Unit of Perception (e.g.morphemes, phrases). Can be decoded into one or more Concepts.
  • Definition: Minimal, but complete explicitation of a concept. Comprises the textual explanation of the concept (sense) and its links to other concepts in a knowledge base. e.g: dictionary definition; consisting solely of a short explanation, with optional term highlights, linking to otther dictionary entries.

Representations:

  1. Formalization of the basic unit of knowledge: the concept.
  2. Information extraction from a linguistic re-source into a set of concepts.
  3. Lexical association: term ↔ concept.
  4. Definition of a term as a composition (mix- ture) of concepts, allowing partial or com-plete disambiguation.

A term is said ambiguous if it is composed by more than one concept.

Lexicons

According to Sowa, there are three variations of factors for lexicons:

  • Accidental
  • Systematic
  • Cultural

Which can be expressed in canonical graphs.

Sowa describes:

  • Concepts
  • Instances
  • Conceptual Relations
  • Type Hierarchy
  • Schema (i.e. frames, scripts, MOPs, scenarios)
  • Inheritance

Knowledge Engineering

1. Indentify the Task

Determine what knowledge must be represented in order to connect problem instances to answers i.e. the PEAS Process:

- Performance Measure (be safe, maximize profits, obey laws)
- Environment (urban streets, weather, customers)
- Actuators: Used to measure the continuous and discrete process variables. 
- Sensors: Used to measure the continuous and discrete process variables.

In our case, PEAS can be: - Performance Measure: Document represents the information - Environment: Computer, Network, Person - Actuators: DOM / - Sensors: Listeners

  1. Assemble the Relevant Knowledge
// 		especially in a particular kind of language or branch of study.
var AxiomTerm = new Thing ('Term Axiom', 'axiom', uuidv4());

∀x∃y RFP(x) - Create(y, x) ∧ Company(y) ∨ → ↔ ¬ 

RFP → Thing 

// [RFP]-()-[Create]-()-[Company]

query: RFP:['#125']

algoC to find , join -> [RFP:'125']-(obj)-[CREATE]-(agent)-[Company:'?']
// Get company  fetch node '125' from gun and traverse create edge and return target of edge

[Person: {Sue, Liz}]-agent-[Dance]


gun.get('Person').get(Sue).put({label:'sue',agent:{label:'dance'}})

var concept = {label:'', function:'', value:''}

gun.set({concept:'', ''}  )

function Thing (label, type, uuid, arcs, value) {
  this.label = label;
  this.type = type; //graph axiom/context, concept, relation
  this.uuid = uuid;
  this.arcs = arcs;
  this.value = value;
  this.concept = []; //concept array for axioms
  this.relation = [];
  
thing => storage => Object.assign(new Thing(), data) 
  
  // Term Axiom
// 		Term: a word or phrase used to describe a thing or to express a concept, 
// 		especially in a particular kind of language or branch of study.
// Language = HTML
  
var AxiomTerm = new Thing ('Term Axiom', 'axiom', uuidv4());
