Eman S. Btoush,Mustafa M. Hammad 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.2
An Entity Relationship (ER) data model is a high level conceptual model that describes information as entities, attributes, and relationships. Entity relationship modeling designed to facilitate database design. The abstract nature of Entity Relationship diagrams can be discouraging task to both designers and student alike. This paper deals with the problem of extracting ER elements from natural language specifications using Natural Language Processing (NLP). The approach provides the opportunity of using natural language documents as a source of knowledge for generating ER data model. The structural approach is used to parse specification syntactically based a predefined set of on heuristics rules. Extracted words with its Part Of Speech (POS) mapped into entities, attributes and relationships, which are the basic elements of ER diagrams.

Nowadays, with the increasingly important role of technology and internet in our world, it has become not only possible, but necessary for organizations that work globally to cooperate in teams that are spread out worldwide. These "Virtual Teams" (VTs) are imperative to the effective functioning of globalized organizations. Therefore, to improve the work of such organizations, it is necessary to study and understand the dynamics of information sharing and international cooperation among these geographically separated VTs. There are many researchers who talk about VTs, but they do not go into deep details about the importance of leadership, conflicting management, and communication tools. We start this research from the points of view of the people who play different roles in VTs. In order to get more realistic results, all the given suggestions and solutions must be more practical and meaningful. Our paper focuses on the factors that should be taken into consideration to get a dynamic VT. As a result, we come up with some advices and recommendations to lead VTs to become as successful as possible based on using communication tools, conflicting management, and leadership skills.
