API

  • ontology_based_matching : build path possibility between an URI and a list of URIs
  • build_graph : get a sequence of chebiid using results from ontology_based_matching
  • graph_html : get html item list using the sequence of chebiid resulting from build_graph
  • get_has_role : get role defining by the RO_0000087 relation about a chebidid
  • get_description : get information about a chebidid

ontology_based_matching Javascript Examples

  • input :

    • chebid a reference ChEBI id : String
    • listChebIds a list of CheBid : Array[String]
    • score (optional) max score to reach : Double (default : 4.5)

  • output : list of object {uri: <string>, property: <string> , score: <double>}

    • uri uri from the input list
    • property possible value : "is_conjugate_acid_of", "is_conjugate_base_of", "has_functional_parent","is_tautomer_of","chas_parent_hydride","is_substituent_group_from", "is_enantiomer_of"
    • score distance between uri and chebid . distance is positive (1.0) when chebid matches a more generic class in the list. The distance is slightly increased (by 0.1) when a relation different tha is_a of the lipid is present in the listChebIds

Scala Example

see example : test

Dev/Test environment (sparql endpoint with ChEBI.owl)

docker-compose up -d

check if the chebi ontology is loaded with docker-compose logs

open ./test.html in the web browser.
