Nested Concept Graphs: Applications for Databases and Mathematical Foundations
While the basic idea of using Conceptual Graphs as query interface to relational databases has already been stated very early in [Sow84], no approach so far has covered the full expressiveness of modern database query languages. Especially negation and the so-called aggregating functions have not been treated. In this paper, we present Nested Concept Graphs with Cuts which extend the syntactica...
متن کاملNested Concept Graphs with Cuts: Mathematical Foundations
Conceptual graphs (CGs) have been developed as a graphic representation system for logic with the very goal to be humanly readable and understandable. They are designed to serve in different fields, one of them is information extraction. The best example for this is querying (relational) databases. There are different symbolic query languages, but these languages got a reputation of either bein...
متن کاملAn Effective Path-aware Approach for Keyword Search over Data Graphs
Abstract—Keyword Search is known as a user-friendly alternative for structured languages to retrieve information from graph-structured data. Efficient retrieving of relevant answers to a keyword query and effective ranking of these answers according to their relevance are two main challenges in the keyword search over graph-structured data. In this paper, a novel scoring function is proposed, w...
متن کاملQuerying Incomplete Graphs with Data
Graph databases underlie several modern applications such as social networks and the Semantic Web. In those scenarios, integrating and exchanging data is very common, which leads to proliferation of incomplete graph data. However, the well developed models of incompleteness of data do not apply to graph data. This is mainly due to the fact that standard graph query languages concentrate on grap...

Deductive Database systems are designed based on a logical data model. Data (as opposed to Relational Databases Management System (RDBMS) in which data stored in tables) are saved as facts in a Deductive Database system. Datalog Educational System (DES) is a Deductive Database system that Datalog mode is the default mode in this system. It can extract data to use outer joins with three query la...
