A cloud-based tool for sentiment analysis in reviews about restaurants on TripAdvisor

The tourism industry has been promoting its products and services based on the reviews that people often write on travel websites like TripAdvisor.com, Booking.com and other platforms like these. These reviews have a profound effect on the decision making process when evaluating which places to visit, such as which restaurants to book, etc. In this contribution is presented a cloud based software tool for the massive analysis of this social media data (TripAdvisor.com). The main characteristics of the tool developed are: i) the ability to aggregate data obtained from social media; ii) the possibility of carrying out combined analyses of both people and comments; iii) the ability to detect the sense (positive, negative or neutral) in which the comments rotate, quantifying the degree to which they are positive or negative, as well as predicting behaviour patterns from this information; and iv) the ease of doing everything in the same application (data downloading, pre-processing, analysis and visualisation). As a test and validation case, more than 33.500 revisions written in English on restaurants in the Province of Granada (Spain) were analyse

Latent Dirichlet Allocation (LDA) for improving the topic modeling of the official bulletin of the spanish state (BOE)

Since Internet was born most people can access fully free to a lot sources of information. Every day a lot of web pages are created and new content is uploaded and shared. Never in the history the humans has been more informed but also uninformed due the huge amount of information that can be access. When we are looking for something in any search engine the results are too many for reading and filtering one by one. Recommended Systems (RS) was created to help us to discriminate and filter these information according to ours preferences. This contribution analyses the RS of the official agency of publications in Spain (BOE), which is known as "Mi BOE'. The way this RS works was analysed, and all the meta-data of the published documents were analysed in order to know the coverage of the system. The results of our analysis show that more than 89% of the documents cannot be recommended, because they are not well described at the documentary level, some of their key meta-data are empty. So, this contribution proposes a method to label documents automatically based on Latent Dirichlet Allocation (LDA). The results are that using this approach the system could recommend (at a theoretical point of view) more than twice of documents that it now does, 11% vs 23% after applied this approach

Programa de orientación profesional a ciclos formativos del I.E.S. Albert Einstein

Este estudio se centra en la propuesta de un programa de orientación a aquellos estudiantes que están realizando los Ciclos Formativos de Grado Medio y Superior en el instituto I.E.S. Albert Einstein. En concreto, en la barriada de Pino Montano, Sevilla. Siguiendo un modelo y una metodología, hemos recogido una Guía para el orientador con la finalidad de asesorar a los estudiantes que cursan estos Ciclos Formativos. Con el objetivo final de ayudarlos hacia la meta que ellos se propongan sin que sus miedos o limitaciones tengan efecto en la toma de sus propias decisiones. Este programa quiere conseguir que los estudiantes desarrollen aspectos personales, académicos, familiares, sociales y de otra índole para así poder reafirmar el empleo al que quiere dedicarse. La Guía del orientador está basada en una serie de sesiones que durante la primera ronda escolar de los Ciclos Formativos del centro logrará que el alumnado se sitúe completamente de forma académica-profesional y laboral

A Non-Parametric Approach to Spatial Causality

The purpose of this paper is to show the capacity of a new non-parametric test based on symbolic entropy and symbolic dynamics to deal with the detection of linear and non-linear spatial causality. The good performance of the new test in detecting spatial causality and causal weighting matrix is notable and gives rise to an expectation that it may form a adequate tool for constructive specification searches.Causality; Spatial Dependence; Spatial Weight Matrices
