The structure equation model (SEM) is a multivariate technique for studying relationships among a set of substantively meaningful variables. The question as to which model best fits the data well, reflects the underlying theory, known as model fit, and is by no means Mohammed Naji Al-Ghamdi, Ezz H. Abdelfattah and Ahmed Ezz 74 much agreed upon. The...

The main core of Structural Equation Modeling (SEM) is the parameter estimation process. This process implies a variance-covariance matrix Σ that is close as possible to the sample variance-covariance matrix of data input (S). The six Sigma survey uses ordinal (rank) values from 1 to 5. There are several weighted correlation coefficients that overc...

Testing of agent systems are difficult comparing with traditional software testing. Agents require special methodologies and techniques that address testing and reliability of these systems. This paper introduces a testing and recovery mechanism for detecting run time errors in agents and agent-based systems. This mechanism is added to a Generic Ag...

Software agents are designed to be mobiles, autonomous, proactive, collaborative, operate asynchronously and in parallel, and communicate through message passing instead of method invocation. Since agents are run autonomously and cooperatively with other agents, so they may run correctly by themselves but incorrectly in a community or vice versa. F...

The preparation of question bank is a difficult and time consuming. This paper explains an algorithm that provides solution to automatic generation of question bank based on a set of pre-defined templates. All possible questions are generated by parameterized concepts from a set of pre-defined templates. The generated questions cover all selected t...

This paper presents a model for building a Semantic News Site (SNS) based on available legacy valuable documents. It consists of four phases: extract the semantic structure for news site; build a unified semantic structure for the group of similar news sites; extract the metadata for each article in the site; and extract the knowledge from the raw...

The E-Learning systems represent a new philosophy in educational organizations. The main features of the E-Learning are the interactions between the instructor and the learners via the electronic instruments, and the personalization of learning material according to learner preferences. This paper introduces a Web-based Learning Environment Archite...

The aim of document layout analysis is to extract the geometric structure for the document image. The introduced system is deigned to work with a variety of documents, without prior knowledge about the nature of the document. This algorithm mainly depends on dividing the document into strips or runs, these runs ease the document handling and enable...
