Anxiety is a painful feeling that depends on a current traumatic situation or an expected threat that its origin is unknown. State anxiety is a transitory emotional state and trait anxiety refers to individual readiness for anxiety that is relatively stable. Besides, cognitive therapists believe that schemas are central for developing and maintaining the chronic forms of trauma, such as persona...

In XML Schema development, the quality of XML Schemas is a crucial issue for further steps in the life cycle of an application, closely correlated with the structure of XML Schemas and different building blocks. Current research focuses on measuring complexity of XML Schemas and mainly do not consider other quality aspects. This paper proposes a novel quality measuring approach, based on existi...

One of the key challenges in the development of open distributed systems is enabling the exchange of meaningful information across applications which (i) may use autonomously developed schemas for organizing locally available data, and (ii) need to discover relations between schemas to achieve their users’ goals. Typical examples are databases using different schemas, and document repositories ...

Semantic matching of schemas in heterogeneous data sharing systems is time consuming and error prone. Existing mapping tools employ semi-automatic techniques for mapping two schemas at a time. In a large-scale scenario, where data sharing involves a large number of data sources, such techniques are not suitable. In this paper we present a method, which creates a mediated schema tree from a larg...

XML is becoming a prevalent format and defacto standard for data exchange in many applications. While traditionally, lots of data are stored and managed in relational databases. There is an urgent need to research some efficient methods to convert these data stored in relational databases to XML format when integrating and exchanging these data in XML format. The semantics of XML schemas are cr...
