Conceptual modelling (CM) involves analysts working with domain experts to create a representation of a domain called a conceptual model. We address two issues in CM research. The first deals with the semantics that conceptual models convey. We propose guidelines for how analysts can reflect the semantics of a “role” in a conceptual model using the extended entity relationship (EER) method. Rol...

Much of the work on automatic user interface (UI) generation has met with limited success because of the added load on the human designer to use specialized scripts for UI specification. In this research in progress, we propose a methodology applicable to database driven systems that a) automatically infers a draft interface directly from an extended entity relationship (EER) model schema and b...

A method for obtaining optimized relational representations of database conceptual schemas in an extended entity-relationship model is first proposed. The method incorporates and generalizes a familiar heuristics to obtain good relational representations and also produces, for each relational structure, an explanation indicating which concepts it represents. Then, a redesign method that, given ...

The structure of the current study is based on to the prior studies on supply chain management practices and perceived organizational performance. The objective of the current study is to create a conceptual framework to investigating the link between supply chain management practices and healthcare’s perceived organizational performance that indicates the mediating impact of alliance integrate...

unreliability of financial statements in iran has urged this country’s financial services industry management to manipulate practices by which they could gain reliable risk scores for borrowers. this research extracts the most influential qualitative factors that would impact the default of a business relationship borrower. solicitation of the factors is done through delphi methodology. the mea...

Previous studies on temporal relation extraction focus on mining sentence-level information or enforcing coherence on different temporal relation types among various event mentions in the same sentence or neighboring sentences, largely ignoring those discourse-level temporal relations in nonadjacent sentences. In this paper, we propose a discourse-level global inference model to mine those temp...

The goal of this paper is to present a framework for factors that influence online relationship development and to discuss a preliminary study with an online research community on users’ attitude towards new system features based on the framework. The article first introduces the motivation of this research, and then a framework for online relationship development is presented. A preliminary st...

Distant supervision is a widely applied approach to automatic training of relation extraction systems and has the advantage that it can generate large amounts of labelled data with minimal effort. However, this data may contain errors and consequently systems trained using distant supervision tend not to perform as well as those based on manually labelled data. This work proposes a novel method...
