Entity linking consists in establishing the relation between a textual entity from a text and its corresponding entity in an ontology. The main difficulty of this task is that a textual entity might be highly polysemic and potentially related to many different ontological representations. To solve this specific problem, various information retrieval techniques can be used. Most of those involve contextual words to estimate which exact textual entity have to be recognized. In this communication, we will explore the question of entity linking and the disambiguation problems it involves. We will describe how a detection and disambiguation resource built from Wikipedia encyclopaedic corpus can be used to establish a link between a named entity (NE) in a text and its normalized ontological representation from the semantic web.
