abstract = {Network Science has become a flourishing interest in the last decades with the Big Data explosion. To improve multidimensional data Recommendation Systems, multiplex graph structures are useful to capture various types of user interactions. We propose a graph database approach to compute multiplex graphs which helps both manipulating dimensions in a flexible way and enhancing expressiveness with algebra to express manipulations on the multiplex graph. Applied operations rely on graph algorithms to predict user interactions. We compare our approach with the traditional matrix approach with Random Walk with Restart. The study shows that combination of scores from layers of multiplex graphs provide important insights into user preferences, with most configurations outperforming traditional matrix methods.

This approach provides a comprehensive analysis of multidimensional recommendation strategies in multiplex graphs, which provides capabilities of managing different dimensions for queries, paving the way for more sophisticated and customized recommendation systems and its explicability.},

abstract = {The health and medicine sector is currently experiencing significant transformations, such as the integration of artificial intelligence in the decision-making process. In this complex system, there is a continuous data flow consisting of quantitative, qualitative, ordinal types, and time series. Hierarchical clustering is a useful tool to handle this complexity. However, clustering mixed data containing time series without distorting the inherent nature of the data poses a challenge. Although there are existing clustering techniques for mixed data or time series, the literature does not address the clustering of mixed data and time series. This paper presents several methodologies for such data clustering, including a novel algorithm based on pretopology. This hierarchical algorithm allows for customizable logical clustering, enabling health experts to better interpret and utilize the results for classification and recommendation by analyzing the hierarchy of clusters.},

abstract = {Nowadays, social networks is become a popular means of analyzing tourist behavior, thanks to the digital traces left by travelers during their stays on these networks. 

The massive amount of data generated by the propensity of tourists to share comments and photos during their trip makes it possible to model their journeys and analyze their behavior. 

Predicting the next movement of tourist plays a key role in tourism marketing to understand demand and improve decision support. 



In this paper, we propose a method to understand and to learn tourists' movements based on social network data analysis to predict the future movements. The method relies on a machine learning grammatical inference algorithm. 

A major contribution in this paper is to adapt the grammatical inference algorithm to the context of big data. 

Our method produces a hidden Markov model representing the movements of a group of tourists. The hidden Markov model is flexible and editable with new data. 

The capital city of France, Paris is selected to demonstrate the efficiency of the proposed methodology.},

The individual behaviour is naturally an indicator of the behaviour of other tourists. The prediction of tourists movement has a crucial role in tourism marketing to create demand and assist tourists in decision-making. With advances in information and communication technology, social media platforms generate data from millions of people from different countries during their travel. The main objective of this paper is to consider sequential data-mining methods to predict tourist movement based on Instagram data. Rules emerge from those ones are exploited to predict future behaviors. The originality of this approach is a combination between pattern mining to reduce the size of data and the automata to condense the rules.
