data-computer

L'instance data-computer utilise l'application ezmaster [lodex-workers`](https://github.com/Inist-CNRS/lodex-workers).

Elle offre plusieurs services asynchrones pour des calculs et de transformations de données simples.

Tous les services proposés acceptent uniquement en entrée des fichiers corpus standards au format tar.gz.

Configuration

Il faut préciser dans le fichier de configuration de l'instance qu'elle utilise les paquets nodejs suivant :

• @ezs/analytics
• @ezs/basics

Bien sûr, les dernières versions sont préférables.

Exemple:

{
    "packages": [
        "@ezs/core@3.0.5",
        "@ezs/analytics@2.1.0",
        "@ezs/basics@2.5.3",
        "@ezs/spawn@1.4.4"
    ]
}

Utilisation

• v1/tree-segment
• v1/graph
• v1/lda

v1/tree-segment

Créer des segments glissant 2 à 2 de tous les éléments d'un tableau et agrège ces segments pour les compter.

Le segment étant glissant, ce traitement sert à créer des segments qui représente un arbre hiérachique.

par exemple avec ces données en entrée:

[
    { "value": ["a", "b", "c"] },
    { "value": ["a", "c", "d"] },
    { "value": ["a", "b", "d"] },
    { "value": ["a", "b", "c", "d"] },
    { "value": ["a", "c", "d", "e"] }
]

on obtiendra :

[
    {"source":"a","target":"b","weight":3,"origin":["#1","#3","#4"]},
    {"source":"b","target":"c","weight":2,"origin":["#1","#4"]},
    {"source":"a","target":"c","weight":2,"origin":["#2","#5"]},
    {"source":"c","target":"d","weight":3,"origin":["#2","#4","#5"]},
    {"source":"b","target":"d","weight":1,"origin":["#3"]},
    {"source":"d","target":"e","weight":1,"origin":["#5"]}
]

NOTE: Le service accepte des tableaux de tableaux (cas d'usage lodex/istex)

v1/graph-segment

Créer des segments 2 à 2 avex tous les éléments d'un tableau et agrège ces segments pour les compter Les segments reprsentent toutes la associations possibles, ce traitement sert à créer des segments qui représente un réesau.

par exemple avec ces données en entrée:

[
    { "value": ["a", "b", "c"] },
    { "value": ["a", "c", "d"] },
    { "value": ["a", "b", "d"] },
    { "value": ["a", "b", "c", "d"] },
    { "value": ["a", "c", "d", "e"] }
]

on obtiendra :

[
    {"source":"a","target":"b","weight":3,"origin":["#1","#3","#4"]},
    {"source":"a","target":"c","weight":4,"origin":["#1","#2","#4","#5"]},
    {"source":"b","target":"c","weight":2,"origin":["#1","#4"]},
    {"source":"a","target":"d","weight":4,"origin":["#2","#3","#4","#5"]},
    {"source":"c","target":"d","weight":3,"origin":["#2","#4","#5"]},
    {"source":"b","target":"d","weight":2,"origin":["#3","#4"]},
    {"source":"a","target":"e","weight":1,"origin":["#5"]},
    {"source":"c","target":"e","weight":1,"origin":["#5"]},
    {"source":"d","target":"e","weight":1,"origin":["#5"]}
]
