Technological advances have allowed to collect and store large volumes of data over the years. Besides, it is significant that today's applications have high performance and can analyze these large datasets effectively. Today, it remains a challenge for data mining to make its algorithms and applications equally efficient in the need of increasing data size and dimensionality [1]. To achieve this goal, many applications rely on parallelism, because it is an area that allows the reduction of cost depending on the execution time of the algorithms because it takes advantage of the characteristics of current computer architectures to run several processes concurrently [2]. This paper proposes a parallel version of the FuzzyPred algorithm based on the amount of data that can be processed within each of the processing threads, synchronously and independently.

Geo-referenced textual data has been the subject of multiple investigations, by providing opportunities to better understand certain phenomena according to the content that is shared, either on-line such as social networks, blogs, and news; or through repositories such as scientific research articles, geo-referenced virtual books, among others. However, the characteristics of this information are studied, analyzed and processed separately, either through its textual components or its geo-spatial components, which offers a separate understanding of the results. In this paper, we propose an integration of textual and geo-spatial components from the pre-processing phase to the visualization stage, As a part of the Document Mapping process based on the phases of the Knowledge Discovery in Databases (KDD). Achieving two main results (1) minimize the problems that arise in the visual phase, su...

In the sustainable tourist sector today, there is a wide margin of loss in small and medium-sized enterprise (SMEs) because of a poor control in logistical expenses. In other words, acquired goods are note being sold, a scenario which is very common in tourism SMEs. These SMEs buy a number of travel packages to big companies and because of the lack of demand of said packages, they expire and they become an expense, not the investment it was meant to be. To solve this problem, we propose a Predictive model based on sentiment analysis of a social networks that will help the sales decision making. Once the data of the social network is analyzed, we also propose a prediction model of tourist destinations, using this information as data source it will be able to predict the tourist interest. In addition, a case study was applied to a real Peruvian tourist enterprise showing their data before ...

The information that flows in the justice system, particularly in Peru, is not shared in real time due to the heterogeneity of its information systems and platforms, generating excessive delay in the judicial process. For this reason, they have been developing interoperability models for this sector for more than a decade, highlighting the European model e-CODEX that integrates fourteen countries with diverse and heterogeneous systems and platforms. However, these models generate information duplication and present difficulty in their implementation due to the legal regulations and standards required. Here, we propose an interoperability model based on data federation for the Peruvian justice sector, this will allow to have information in real time, distributed, without duplicity, transparent to the user and easy to implement for heterogeneous and inherited systems and platforms. The pro...

Micro finance organizations play an important role since they facilitate integration of all social classes to sustained economic growth. Against this background, exponential growth of data, resulting from transactions and operations carried out with these companies on a daily basis, becomes imminent. Appropriate management of this data is therefore necessary because, otherwise, it will result in a competitive disadvantage due to the lack of valuable and quality information for decision-making and process improvement. Data Governance provides a different approach to data management, as seen from the perspective of business assets. In this regard, it is necessary that the organization have the ability to assess the extent to which that management is correct or is generating expected results. This paper proposes a data governance maturity model for micro finance organizations, which frames ...

This article presents an experience carried out by the faculty of the third year of the Infant Education degree at the Ramon Llull University in Barcelona (Spain). A proposal for multidisciplinary intervention that joins two modules: one for arts (musical, corporal, visual, and plastic education) and another for sciences (mathematics, and experimental and social sciences). The intervention stems from a generating idea—the book “Alice in Wonderland”—which allows for connections between the contents of the modules, involves co-teaching, multidisciplinary work, and shared evaluation experiences. The aim of the study is to get to know the perception of the participating faculty about the changes in the didactic components involved in the experience. For data collection, semi-structured interviews were carried out at three moments of the process and a discussion group at the end. The ...

This paper discusses the Hawkes process to modeling of the offering book, especially the ETF it iShare Ibovespa index fund. The study aimed to investigate the dynamics of the influences of the offers in relation to the past orders. We study too to the interaction of the order rates of the opposing sides of the Book. Another point addressed is the verification of the operating strategy that captures the dynamics studied. At the first moment, the univariate approach was performed and in the second moment the multivariate of the Hawkes process. The results show that in both cases the Hawkes process it fits well to the data. The fit model indicates that agents have similar behaviors when they act as buyers or sellers of assets. As for the strategy, it was not possible to establish spare gains from changes in bid rates. However, these results are due to the it bid-ask spread more that the pre...

The purpose of the study was to describe the need for decision-making from the conceptualized training between Statistics and Data Science. Four elements are key in science: theory, data, methodology, and problem, because if the data is part of science then it seems wrong that there is a DataScience since no methodology from Data Science can decide, the “ideal or correct” pattern since there are multiple patterns to be understood. On the other hand, if the statistical programs are incapable of analyzing hundreds of thousands of data (it makes no sense when decisions are recognized from a random probabilistic sample and, on the contrary, not considered makes it impossible to make inferences), then the possibility of representing diversity from Statistics is limited since there is centralization in minimizing the sums of the deviations to the mean square and not understanding the diver...

In this study, we investigate changes in the glaciated surface and the formation of lakes in the headwater of the Querococha watershed in Cordillera Blanca (Peru) using 24 Landsat images from 1975 to 2014. Information of glacier retreat was integrated with available climate data, the first survey of recent depositional dynamics in proglacial Yanamarey Lake (4600m a.s.l.), and a relatively short hydrological record (2002-2014) at the outlet of Yanamarey Lake. A statistically significant temperature warming (0.21°C decade-1 for mean annual temperature) has been detected in the region, and it caused a reduction of the glacierized area since 1975 from 3.5 to 1.4km-2. New small lakes formed in the deglaciated areas, increasing the flooded area from1.8ha in 1976 to 2.8ha in 2014. A positive correlation between annual rates of glacier recession and runoff was found. Sediment cores revealed a h...

This article aspires to be a contribution to an anthropological approach on housing and habitat, understanding both notions as complex socio-cultural phenomena. In this sense, our aim is to reflect —from an ethnographic point of view— on the processes whereby living spaces are appropriated, as well as to reflect on certain features that neighbors’ sociability adopts in a social-interest housing complex built as a large urban unit in the South-East area of Buenos Aires, specifically in the barrio of Villa Soldati. In order to do so, we made a distinction between planned spaces and developed spaces, and also differentiated three uses of the common and shared spaces in this particular housing complex: spaces with idle use, incompatible use and uncivil use. The qualitative methodology used in this study was based on a still ongoing field work, which included field observation and non-d...
