Ontology based document annotation: trends and open research problems
نویسنده
چکیده
Metadata is used to describe documents and applications, improving information seeking and retrieval and its understanding and use. Metadata can be expressed in a wide variety of vocabularies and languages, and can be created and maintained with a variety of tools. Ontology based annotation refers to the process of creating metadata using ontologies as their vocabularies. We present similarities and differences with respect to other approaches for metadata creation, and describe languages and tools that can be used to implement these annotations.

AO: An Open Annotation Ontology for Science on the Web
We present the Annotation Ontology (AO), an open ontology in OWL for annotating scientific documents on the web. AO supports both human and algorithmic content annotation. It enables “stand-off” (separate) metadata anchored to specific positions in a web document by any one of several methods. In AO, the document may be annotated but is not required to be under update control of the annotator. ...

متن کاملUsing ontology-based annotation to profile disease research
BACKGROUND Profiling the allocation and trend of research activity is of interest to funding agencies, administrators, and researchers. However, the lack of a common classification system hinders the comprehensive and systematic profiling of research activities. This study introduces ontology-based annotation as a method to overcome this difficulty. Analyzing over a decade of funding data and p...
متن کاملCombination of DROOL rules and Protégé knowledge bases in the ONTO-H annotation tool
ONTO-H is a semi-automatic collaborative tool for the semantic annotation of documents, built as a Protégé 3.0 tab plug-in. Among its multiple functionalities aimed at easing the document annotation process, ONTO-H uses a rule-based system to create cascading annotations out from a single drag and drop operation from a part of a document into an already existing concept or instance of the domai...
متن کاملAn Ontology Based Model for Document Clustering
Clustering is an important topic to find relevant content from a document collection and it also reduces the search space. The current clustering research emphasizes the development of a more efficient clustering method without considering the domain knowledge and user’s need. In recent years the semantics of documents have been utilized in document clustering. The discussed work focuses on the...
