Temporal entity-relationship models-a survey

IEEE Transactions on Knowledge and Data Engineering, 1999
The entity-relationship (ER) model, using varying notations and with some semantic variations, is enjoying a remarkable and increasing popularity in both the research community-the computer science curriculum-and in industry. In step with the increasing diffusion of relational platforms, ER modeling is growing in popularity.

Deductive entity relationship modeling

IEEE Transactions on Knowledge and Data Engineering, 1993
An entity relationship oriented model, that includes the notion of class, together with different types of assertions on classes, is presented. The assertions are used to model IS-A and disjointness relations both between entities and between relationships, part-of relations between entities and relationships, mandatory participation of an entity in a ...

Entity-relationship modeling

IEEE Potentials, 1995
The entity-relationship (ER) model and its accompanying ER diagrams are widely used for database design and systems analysis. Many books and articles just provide a definition of each modeling component and give examples of the pre-built ER diagrams.

ERA-CoT: Improving Chain-of-Thought through Entity Relationship Analysis

Annual Meeting of the Association for Computational Linguistics
Large language models (LLMs) have achieved commendable accomplishments in various natural language processing tasks. However, LLMs still encounter significant challenges when dealing with complex scenarios involving multiple entities.

The Entity-Relationship Model

1999
The Entity-Relationship model (abbreviated to ER model) is a data model, which allows us to model the semantics of a conceptual database schema. Actually, the ER model is only a partial data model, since it only caters for the data structure and integrity constraint parts of a data model with no provision being made for a query and update language.
