Similarity search on neighbor's graphs with automatic Pareto optimal performance and minimum expected quality setups based on hyperparameter optimization
Eric S. Tellez, Guillermo Ruiz
This manuscript introduces an autotuned algorithm for searching nearest neighbors based on neighbor graphs and optimization metaheuristics to produce Pareto-optimal searches for qu…
Regionalized models for Spanish language variations based on Twitter
Eric S. Tellez, Daniela Moctezuma, Sabino Miranda +2
Spanish is one of the most spoken languages in the globe, but not necessarily Spanish is written and spoken in the same way in different countries. Understanding local language var…
A Case Study of Spanish Text Transformations for Twitter Sentiment Analysis
Eric S. Tellez, Sabino Miranda-Jiménez, Mario Graff +3
Sentiment analysis is a text mining task that determines the polarity of a given text, i.e., its positiveness or negativeness. Recently, it has received a lot of attention given th…
A Python Library for Exploratory Data Analysis on Twitter Data based on Tokens and Aggregated Origin-Destination Information
Mario Graff, Daniela Moctezuma, Sabino Miranda-Jiménez +1
Twitter is perhaps the social media more amenable for research. It requires only a few steps to obtain information, and there are plenty of libraries that can help in this regard.…
Improving classification performance by feature space transformations and model selection
Jose Ortiz-Bejar, Eric S. Tellez, Mario Graff
Improving the performance of classifiers is the realm of feature mapping, prototype selection, and kernel function transformations; these techniques aim for reducing the complexity…
EvoMSA: A Multilingual Evolutionary Approach for Sentiment Analysis
Mario Graff, Sabino Miranda-Jiménez, Eric S. Tellez +1
Sentiment analysis (SA) is a task related to understanding people's feelings in written text; the starting point would be to identify the polarity level (positive, neutral or negat…
A scalable solution to the nearest neighbor search problem through local-search methods on neighbor graphs
Eric S. Tellez, Guillermo Ruiz, Edgar Chavez +1
Near neighbor search (NNS) is a powerful abstraction for data access; however, data indexing is troublesome even for approximate indexes. For intrinsically high-dimensional data, h…
An Automated Text Categorization Framework based on Hyperparameter Optimization
Eric S. Tellez, Daniela Moctezuma, Sabino Miranda-Jímenez +1
A great variety of text tasks such as topic or spam identification, user profiling, and sentiment analysis can be posed as a supervised learning problem and tackle using a text cla…
A Simple Approach to Multilingual Polarity Classification in Twitter
Eric S. Tellez, Sabino Miranda Jiménez, Mario Graff +3
Recently, sentiment analysis has received a lot of attention due to the interest in mining opinions of social media users. Sentiment analysis consists in determining the polarity o…
