This project makes use of an open-source data English-Akuapem Twi parallel corpus. Training the dataset on a sequence-to sequence model reveals a stereotypical bias in the machine translation system associated with a high-status profession like 'engineering. ' The quality of translation for sentences associated with 'he' is higher than 'she.' Hence, a proposed data design approach is made to help examine bias in the dataset. The quality of the translation of sentences associated with either 'he' or 'she' improved and got either identical bleu scores or just a little difference in the bleu scores.

Notwithstanding the wellcrafted nature and noble intentions of the GETFund policy, its implementation has suffered setbacks. Analysis of data collected revealed that GETFund has been politicized. Its implementation has generated conflict among competing forces including disagreements, suspicions and an effort to sidestep frontline institutions and individuals tasked with the responsibility to administer the fund. These political interferences the study revealed have undermined the attainment of the objectives of the Fund. Proposals to improve on the implementation of GETFund such as a depoliticized process of application of GETFund would free it from the manipulations by politicians and their bureaucratic collaborations.
