A novel approach for learning ontology from relational database: from the construction to the evaluation

Bilal Ben Mahria, Ilham Chaker, Azeddine Zahi
2021 Journal of Big Data  
This is the reason why bridging the gap between relational databases and ontologies has attracted the interest of the ontology community from early years, and it is commonly referred to as the database-to-ontology  ...  database based on the predefined life cycle; (3) add three new semantics that can be extracted from RDB; (4) we suggest an evaluation process based on two categories of metrics: (i) conceptual ontology (TBox  ...  After the data acquisition, the schema acquisition (TBox) [22] will be started in order to generate the definition and the meaning of the extracting instances.  ...

A Survey on how Description Logic Ontologies Benefit from Formal Concept Analysis [article]

Baris Sertkaya
2011 arXiv   pre-print
Although the notion of a concept as a collection of objects sharing certain properties, and the notion of a conceptual hierarchy are fundamental to both Formal Concept Analysis and Description Logics,  ...  the ways concepts are described and obtained differ significantly between these two research areas.  ...  Enriching FCA with DL constructors Theory-driven logical scaling In [45] , Prediger and Stumme have used DLs in Conceptual Information Systems, which are data analysis tools based on FCA.  ...

Abductive Reasoning Using Tableau Methods for High-Level Image Interpretation [chapter]

Yifan Yang, Jamal Atif, Isabelle Bloch
2015 Lecture Notes in Computer Science  
Image interpretation is a dynamic research domain involving not only the detection of objects in a scene but also the semantic description considering context information in the whole scene.  ...  In this work, we present a framework using a tableau method for generating and selecting potential explanations of the given image when the background knowledge is encoded using a description that is able  ...  Let T be a TBox and a set of axioms formulated as C i D i .  ...

Axiomatic Ontology Learning Approaches for English Translation of the Meaning of Quranic Texts

Saidah Saad, Bahari Idrus, M.N. Nik Hisyamudin, K. Amir, I. Al Emran, I. Mohd Rasidi, M.B. Mohd Faizal, Md J. Mohd Azlis Sani, T.A. Ahmad Mubarak, Z. Izzuddin, M. Sofian
2017 MATEC Web of Conferences  
The ontology that is created not only stores the information about the application domain in explicit knowledge, but also can deduce the implicit knowledge from this ontology.  ...  Lexico-syntactic pattern matching and statisticsal one cannot lead to very accurate learning, mostly because of several linguistic nuances in the NL.  ...  Ontology ideally consists of a TBox and an ABox.  ...
