Automatic annotation of multilingual text collections with a conceptual thesaurus
Automatic annotation of documents with controlled vocabulary terms (descriptors) from a conceptual thesaurus is not only useful for document indexing and retrieval. The mapping of texts onto the same thesaurus furthermore allows to establish links between similar documents. This is also a substantial requirement of the Semantic Web. This paper presents an almost language-independent system that...
متن کاملUnsupervised Text Annotation
We introduce the unsupervised text annotation model UTA, which iteratively populates a document-specific database containing the related symbolic content description. The model identifies the most related documents using the text of documents and the symbolic content description. UTA extends the database of one document with data from related documents without ignoring the precision.
متن کاملTemporal Annotation of Clinical Text
We developed a temporal annotation schema that provides a structured method to capture contextual and temporal features of clinical conditions found in clinical reports. In this poster we describe the elements of the annotation schema and provide results of an initial annotation study on a document set comprising six different types of clinical reports.
متن کاملUniversal Conceptual Cognitive Annotation (UCCA)
Syntactic structures, by their nature, reflect first and foremost the formal constructions used for expressing meanings. This renders them sensitive to formal variation both within and across languages, and limits their value to semantic applications. We present UCCA, a novel multi-layered framework for semantic representation that aims to accommodate the semantic distinctions expressed through...
متن کاملConceptual Clustering of Text Clusters
Common clustering techniques have the disadvantage that they do not provide intensional descriptions of the clusters obtained. Conceptual Clustering techniques, on the other hand, provide such descriptions, but are known to be rather slow. In this paper, we discuss a way of combining both techniques. We rst cluster the documents by a variant of k{Means, using a thesaurus as background knowledge...
