Reconnaissance d'entités nommées itérative sur une structure en dépendances syntaxiques avec l'ontologie NERD
Abstract
Named entity recognition (NER) seeks to locate and classify named entities into predefined
categories (persons, organizations, brandnames, sports teams, etc.). NER is often considered as
one of the main modules designed to structure a text. In this article, we describe our symbolic
system which is characterized by 1) the use of limited resources, and 2) the embedding of
results from other modules such as coreference resolution and relation extraction. The system
is based on the output of a dependency parser that adopts an iterative execution flow that
embeds results from other analysis blocks. At each iteration, candidate categories are generated
and are all considered in subsequent iterations. The advantage of such a system is to select
the best candidate only at the end of the process in order to take into account all the elements
provided by the different modules. The system is compared to academic and industrial systems.
