ER Diagramstands for Entity Relationship Diagram, also known as ERD is a diagram that displays the relationship of entity sets stored in a database. In other words, ER diagrams help to explain the logical structure of databases. ER diagrams are created based on three basic concepts: entities, ...

FIG. 15 is a block diagram illustrating the inputs and the outputs of the model building process performed by the relationship, discovery and analysis module shown in FIG. 2. Predictive models for the estimation of age, gender and HHI are constructed using a combination of previous observed beh...
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing ...
ERD Symbols and Meanings Entity Relationship Diagram Symbols Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements.

The traditional pipeline extraction approach is to first construct a model for extracting entities with specific meanings in the text [3], and later, another model to classify relations on the results of entities extracted by the previous named entity recognition model [4]. Although the pipeline ...
