English language textbook production in Cape Verde: Assets and obstacles

This study investigates if Cape Verde can be successful in the production of English language textbooks. It also will be looked at the main reasons why locally produced textbooks would be advantageous. The findings of the study reveal that the production of an English language textbook for Cape Verde is the best solution and that it can be successful. We also find out that Capeverdean English teachers have professional competence and pedagogical qualification to be engaged in this practice. However, significant assistance will be necessary for bringing experts to the country to supervise the process. It also will be necessary to find financial support to put it in practice.

Making Predictions with Textual Contents

Forecasting real-world quantities with basis on information from textual descriptions has recently attracted significant interest as a research problem, although previous studies have focused on applications involving only the English language. This document presents an experimental study on the subject of making predictions with textual contents written in Portuguese, using documents from three distinct domains. I specifically report on experiments using different types of regression models, using state-of-the-art feature weighting schemes, and using features derived from cluster-based word representations. Through controlled experiments, I have shown that prediction models using the textual information achieve better results than simple baselines such as taking the average value over the training data, and that richer document representations (i.e., using Brown clusters and the Delta- TF-IDF feature weighting scheme) result in slight performance improvements.
