Generate a meta knowledge graph of how biomedical concepts are connected based on SmartAPI Specifications with built-in filtering capabilities

npm i @biothings-explorer/smartapi-kg

• Import and Initialize

  const kg = require("@biothings-explorer/smartapi-kg")
  //initiate a new knowledge graph class
  let meta_kg = new kg.default()

• Load the Meta Knowledge Graph (meta-kg)

  • Option 1: Load Meta-KG from SmartAPI specs with translator tag specified

    //async load knowledge graph from SmartAPI
    await meta_kg.constructMetaKG()

  • Option 2: Load Meta-KG from SmartAPI specs with translator tag as well as ReasonerStdAPI with /predicates endpoint

    await meta_kg.constructMetaKG(includeReasoner=true);

  • Option 3: Load Meta-KG from SmartAPI specs with tags equal to biothings

    await meta_kg.constructMetaKG(includeReasoner = false, {tag: "biothings"});

  • Option 4: Load Meta-KG from SmartAPI specs with team name equal to Text Mining Provider

    await meta_kg.constructMetaKG(includeReasoner = false, {teamName: "Text Mining Provider"});

  • Option 5: Load Meta-KG from SmartAPI specs with component equal to KP

    await meta_kg.constructMetaKG(includeReasoner = false, {component: "KP"});

  • Option 6: Load Meta-KG for a specific SmartAPI spec with SmartAPI ID

    await meta_kg.constructMetaKG(includeReasoner = false, {smartAPIID: "5076f09382b38d56a77e376416b634ca"});

  • Option 7: Load Meta-KG from a local copy of SmartAPI specs included in the package

    //Alternatively, you can also sync load SmartAPI specs from a local copy within the package
    meta_kg.constructMetaKGSync();

  • Option 8: Load Meta-KG from file path you specify

      const path = require("path");
      // provide file path storing your SmartAPI file
      const file_path = path.resolve(__dirname, '../data/smartapi_multiomics_kp_query.json');
      let meta_kg = new MetaKG(file_path);
      meta_kg.constructMetaKGSync();

• Filter the Meta-KG for specific associations based on input, output, predicate, or api combinations.

  //filter based on predicate
  meta_kg.filter({predicate: 'treats'})
  //filter based on predicate and input_id
  meta_kg.filter({predicate: 'treats', input_id: 'CHEMBL.COMPOUND'})
  //filter based on predicate and input_type
  meta_kg.filter({predicate: ['treats', 'physically_interacts_with'], input_type: 'ChemicalSubstance'})
  //filter based on input_type, output_type and api
  meta_kg.filter({ api: "Automat PHAROS API", input_type: "ChemicalSubstance", output_type: "Gene" });
