ONYX: A System for the Semantic Analysis of Clinical Text
نویسندگان
چکیده
This paper introduces ONYX, a sentencelevel text analyzer that implements a number of innovative ideas in syntactic and semantic analysis. ONYX is being developed as part of a project that seeks to translate spoken dental examinations directly into chartable findings. ONYX integrates syntax and semantics to a high degree. It interprets sentences using a combination of probabilistic classifiers, graphical unification, and semantically annotated grammar rules. In this preliminary evaluation, ONYX shows inter-annotator agreement scores with humans of 86% for assigning semantic types to relevant words, 80% for inferring relevant concepts from words, and 76% for identifying relations between concepts.

Automatic identification of words with semantic roles (such as Agent, Patient, Source, etc.) in sentences and attaching correct semantic roles to them, may lead to improvement in many natural language processing tasks including information extraction, question answering, text summarization and machine translation. Semantic role labeling systems usually take advantage of syntactic parsing and th...

Text clustering and classification are two main tasks of text mining. Feature selection plays the key role in the quality of the clustering and classification results. Although word-based features such as term frequency-inverse document frequency (TF-IDF) vectors have been widely used in different applications, their shortcoming in capturing semantic concepts of text motivated researches to use...
متن کاملSemiautomatic Image Retrieval Using the High Level Semantic Labels
Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...

Abstract Extracting semantic roles is one of the major steps in representing text meaning. It refers to finding the semantic relations between a predicate and syntactic constituents in a sentence. In this paper we present a semantic role labeling system for Persian, using memory-based learning model and standard features. Our proposed system implements a two-phase architecture to first identify...
