MSc in Computer Science at São Paulo University, Brazil. I have interest in Natural Language Processing and Natural Language Generation. I am research engineer at Inria, France. Previously, I worked in other NLP research projects. I received the bachelor's degree from San Agustin National University, Peru.
MSc @ São Paulo University - Brazil
Master of Science in Computer Science
Monograph title: Automatic Aspect-Based Opinion Summarization Methods
In this master’s project are presented investigations to generate extractive and abstractive summaries of opinions using an aspect-based approach. Besides using known methods in the area, it also was proposed two new methods for Portuguese language which got the best performance in the experiments.
BSc @ San Agustin National University - Peru
Bachelor of Science in Computer Science
In this monograph, it is presented a method to classify medical documents which improves the results of Naive Bayes and Rocchio algorithm. This method, in addition to onsidering statistical information, taking into account the semantic relatedness between the keywords of medical documents.
Research Engineer - Inria
from February 2017 to present
I am working on extracting symbolic knowledge about objects and their characteristics from unstructured text (relying on natural language processing and machine reading techniques), as well as available ontologies and knowledge on the Semantic Web.
CTO - DoctorCV
from October 2016 to present
Peruvian startup which evaluates and proposes improvements in your CV using NLP techniques. It is like having a virtual recruiter expert who will tell what to change in the resume to increase the chances of being called to the job interview.
Researcher, Software Engineer - Elabora
from July 2015 to January 2017
I researched some information retrieval methods and word embedding representations to create hierarchies of terms in collections of patent about different topics. In this project, I used Spark, HBase and Python.
Software Engineer - Dicionário Criativo
from October 2013 to December 2013
I implemented a crawler for Twitter in Python. This crawler collects public comments about music, books and films. I also developed a module to normalize these comments (spell checker, etc.). With this data and other resources the database was increased.
Researcher, Developer - Lindexa
from January 2012 to December 2012
Lindexa - Wayra Telefónica
I researched and developed some automatic techniques of Opinion Mining and Sentiment Analysis for Spanish language. In addition, I implemented a crawler for Facebook and Twitter in Python. This crawler collects all public comments written on these social networks. Lindexa is a winner startup of the first edition of Wayra Peru.
Technical Researcher, Developer - Concytec
from January 2011 to December 2011
In general, we researched techniques to generate extractive summaries of many texts. These summaries represent the most important data. I also researched and implemented Text Classification and Clustering algorithms.
