Structured Data Extraction from Scanned PDFs
This is a TensorFlow ML project designed to help reporters trace the money spent in US election cycles; we achieved a state-of-the-art performance for extracting the candidate's name, the dates the commercials aired, and amount spent on them.

Spanish Stemmer
A lemmatizer/stemmer to extract stemmed tokens from Spanish text to build a word-frequency table that was independent of different conjugations and word forms.
