Contextual and Metadata-based Approach for the Semantic Annotation of Heterogeneous Documents

We present SHIRI-Annot an automatic ontology-driven and unsupervised approach for the semantic annotation of documents which contain well structured parts and not well structured ones. The aim of this approach is to build an integration system called SHIRI 3 which allows the user access to documents related to a specific domain. In this system, the querying process is guided by an ontology of the domain and the answers are only made of the pertinent parts of the documents unlike keywords-based search engines. The ontology describing the domain of interest is defined using a set of concepts, their properties, their relations and the associated cardinalities. The approach consists of locating and then annotating concept instances and their semantic relations. The locating step combines existing annotation approaches in order to locate instances in the text. The annotation step exploits a set of metadata and a set of logical rule patterns which are automatically instanciated from the doma...
