Nowadays, the tourism industry accounts for approximately 10% of the global GDP, while it only contributes 3% of the economy in Iran. Since the pressure of US sanctions increases day after day on the Iranian economy, the necessity of paying attention to this industry as a source of foreign currency is felt more than ever. The purpose of this research is to analyze the reviews of users of social...

The increasingly complex business environment necessitates businesses to design more effective and efficient strategies for company development, including market expansion. To understand customer behaviors, data analysis becomes crucial. One common approach used group customers is segmentation based on RFM (Recency, Frequency, Monetary). This study aims compare the performance of two clustering...

Many researchers have proposed algorithms to improve the network performance of vehicular ad hoc (VANET) clustering techniques for different applications. The effectiveness model is most important challenge. K-Means algorithm an effective multi-clusters that can be used in VANETs. problems with concern selection a suitable number clusters, creation highly reliable cluster, and achieving high si...

Abstract There may be several internal defects in railway track work that have different shapes and distribution rules, these affect the safety of high-speed trains. Establishing reliable detection models methods for remains a challenging task. To address this challenge, study, an intelligent method based on generalization feature cluster is proposed tracks. First, are classified counted accord...

Text mining is a powerful modern technique used to obtain interesting information from huge datasets. clustering distinguish between documents that have the same themes or topics. The absence of datasets ground truth enforces use (unsupervised learning) rather than others, such as classification (supervised learning). “no free lunch” (NFL) theorem supposed no algorithm outperformed other in var...

The imagination and creativity of children is often puzzling to the adult mind. Pretend play and make-believe friends are often prevalent in the life of a child. Past research shows a relationship between the use of the imagination in children’s play and their social, cognitive, and emotional development. Furthermore, there are a number of gender differences in the type of imaginary play and pr...

Competitive intelligence (CI) has become one of the major subjects for researchers in recent years. The present research is aimed to achieve a part of the CI by investigating the scientific articles on this field through text mining in three interrelated steps. In the first step, a total of 1143 articles released between 1987 and 2016 were selected by searching the phrase "competitive intellige...

Stunting has been widely known as the highest case of malnutrition suffered by toddlers in world and a bad impact on children's future. In 2018, Indonesia was ranked 31st stunting 4th Southeast Asia. About 30.8% (roughly 3 out 10) children under 5 years suffer from Indonesia. To support government policy making handling stunting, it is undoubtedly necessary to classify levels regions this work,...

OBJECTIVE Self-paced EEG-based BCIs (SP-BCIs) have traditionally been avoided due to two sources of uncertainty: (1) precisely when an intentional command is sent by the brain, i.e., the command onset detection problem, and (2) how different the intentional command is when compared to non-specific (or idle) states. Performance evaluation is also a problem and there are no suitable standard metr...
