Item categorization is an important application of text classification in e-commerce due to its impact on the online shopping experience of users. One class of text classification techniques that has gained attention recently is using the semantic in
formation of the labels to guide the classification task. We have conducted a systematic investigation of the potential benefits of these methods on a real data set from a major e-commerce company in Japan. Furthermore, using a hyperbolic space to embed product labels that are organized in a hierarchical structure led to better performance compared to using a conventional Euclidean space embedding. These findings demonstrate how label-guided learning can improve item categorization systems in the e-commerce domain.

The current research is aimed at scaling Psychasthenia scale of
Minnesota Multiphasic Personality Inventory 2 , access to a new
form and brief to the test, it,s liberal from the sample and items
properties, using one and pair parameter models, and
testing the
effect of two variables in the results of scaling Psychasthenia scale
(the model used, the sample size) with using criteria of accuracy as
the Standard Error, Relaibility and Information Function.
This study aimed at finding out the differences in item difficulty parameter
estimations for Simulated Data having (MC1- PL) Model in Item Response Theory (IRT)
according to the differences in a test Dimensions (3D; 2D; 1D), correlations between th
ese
dimensions (0.0, 0.50, 0.86), and the statistical program used in analyzing the data
(NOHARM ؛Bilog- MG3). The Monte Carlo simulations data having (MC1- PL) Model in
IRT using (RESGENT) program; that fully filled in a 21-item was used to achieve the
study aims. Data were analyzed using the statistical programs (NOHARM ؛Bilog- MG3).
The results revealed no statistically significant differences in item difficulty
parameter estimations that construct the multidimensional test within items due to
differences in a test, correlations between these dimensions, and the statistical program
used in analyzing the data (NOHARM ؛Bilog- MG3), as well as the estimations were
consistent and high. Finally, the study recommends using these statistical programs for a
data having (MC1- PL) Model, especially when similar assumptions are satisfied in a real
data.
This research aims to identify the range of awareness of fraud practices and
deception in the areas of marketing item, price, promotion and distribution, and to study
the differences in the level of awareness of these practices according to variabl
es of
gender, age and academic qualification. To achieve the objectives of the research, a
questionnaire is designed and distributed to (271) consumers in Lattakia City. After deep
analysis and study, the following conclusions have been reached:
1. The consumers in Lattakia City are fully aware of fraud and deceit regarding the
product, price, promotion and distribution.
2. There are no statistically significant differences among the levels of food
consumers’ awareness of the practices of fraud and deceit regarding the variables
of gender and age.
3. There are statistically significant differences in the levels of food consumers’
awareness of practices of fraud and deceit regarding the variable of academic
qualification. The higher their academic qualifications are, the more the
consumers are aware of these practices.
