OVERVIEW

This UIMA Analysis Engine (AE) allows you to run Shell command over a Common Analysis Structure (CAS) element (view or annotation) and to store the result either as a new view or a new annotation.

It mainly aims at running within a UIMA aggregate processing chain some external tools available via command line. These tools should perform their processing by taking the input as a file name parameter or a standard input ( stdin ) and produce the result via the standard output ( stdout ).

With the uima-connectors project, this current component aims at solving interoperability issues when dealing with non native UIMA tools.

The input must be either the SofaDataString of a specified view, or the value of an annotation String feature which should also be specified (e.g. org.apache.uima.TokenAnnotation and coveredText ). It is possible to only process some annotations belonging themselves to some parts of the sofa specified also as an annotation. The processing result can be saved as either the SofaDataString of a newly created view or the string feature value of a newly created annotation.

FEATURES

• implémentation d'un AE réalisant une commande SHELL sur un élément input du CAS (vue|annotation) et produisant un nouvel élément output (vue|annotation) au sein du CAS
• traitement utilisant l'API SHELL de F. Martini (alias adiGuba) distribuée sous licence CeCILL-C et qui permet de simplifier l'exécution de programme et de ligne de commande depuis Java.
• gestion de multiples formats des commandes à exécuter où la donnée à traiter peut aussi bien provenir de l'entrée standard ou constituer un fichier texte passé en argument, être récupéré du système de fichier, pipé, redirigé...
• traitement de la commande SHELL sous forme d'un thread
• paramétrage libre et générique des éléments du CAS (view/annotation/feature) d'entrée (à traiter) et de sortie (à créer) notamment à l'aide de l'API java.lang.reflect (constitue des exemples de code générique)
