Eliciting hierarchical structures from enumerative structures for ontology learning

Some discourse structures such as enumerative structures have typographical, punctuational and laying out characteristics which (1) make them easily identifiable and (2) convey hierarchical relations which provide ontology fragments clues. This study will try to show how these textual objects can be exploited in order to considerably improve the process of ontology enrichment from text. Categories and Subject Descriptors General Terms Algorithms, Documentation, Languages Keywords Ontology learning, discourse theory, document structure, enumerative structure. ENUMERATIVE STRUCTURES A written text is not merely a set of words or of sentences. First its semantic and rhetoric coherence must be granted by discourse relations which can be formalized through different discourse theories [5]. Second, it implements typographical, punctuation and layout means, which also contribute to identify its meaning and which can be formalized through text structure models [4]. For instance, enumeration i...
