What are Ontologies Good For? Evaluating Terminological Ontologies in the Framework of Text Graph Classification
نویسندگان
چکیده
This paper develops a graph-theoretical model of text representation based on lexical chaining. Other than present approaches to chaining, this model reflects the logical document structure of texts as well as semantic relations of their lexical constituents in order to compute text similarity values. By varying the terminological ontology used to induce such relations, a door is opened to systematically evaluate their contribution to text classification. This is exemplified by example of GermaNet and the Wikipedia.

Background and Aim: Ontologies facilitate data integration, exchange, searching and querying. Open Biomedical Ontologies (OBO) Foundry is a solution for creating reference ontologies. In this foundry, the design of ontologies is based on established principles which allow for their interactions as a single system. The purpose of this study is to determine the main features of ontologies develop...

Extracting structured information about entities from web texts is an important task in web mining, natural language processing, and information extraction. Information extraction is useful in many applications including search engines, question-answering systems, recommender systems, machine translation, etc. An information extraction system aims to identify the entities from the text and extr...
متن کاملCentralized Clustering Method To Increase Accuracy In Ontology Matching Systems
Ontology is the main infrastructure of the Semantic Web which provides facilities for integration, searching and sharing of information on the web. Development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. By emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...
متن کاملLearning Relations for Terminological Ontologies from Text
The problem of learning concept hierarchies and terminological ontologies can be decomposed into two sub-tasks: concept extraction and relation learning. We describe an new approach to learn relations automatically from unstructured text corpus based on one of the probabilistic topic models, Latent Dirichlet Allocation. We first provide definition (Information Theory Principle for Concept Relat...
