ABSTRACT
Syntactic and semantic ambiguity affect the text retrieval task as each type of ambiguity influences precision and/or recall. In this work we provide an experimental study on the effect of several ambiguity types in IR, by resolving each ambiguity type separately and adding respective annotations in the indexed text. We focus on five small text retrieval collections.

Leveraging the Impact of Ontology Evolution on Semantic Annotations
Knowledge Engineering and Knowledge ManagementAbstractThis paper deals with the problem of maintenance of semantic annotations produced based on domain ontologies. Many annotated texts have been produced and made available to end-users. If not reviewed regularly, the quality of these annotations ...
