OCR produces inaccurate text

I’m using trial version of aspose ocr .net for testing its capability to recognize text in various settings, I’m comparing its result with open source OCR’s and it produces quite inaccurate results, I’ve attached the document image,

Abstract: In this paper, we study the usage of machine-learning models for sales predictive analytics.
‘The main goal of this paper is to consider main approaches and case studies of using machine learning,
for sales forecasting, The effect of machine-learning generalization has been considered. This effect
can be used to make sales predictions when there is a small amount of historical data for specific
sales time series in the case when a new product or store is launched. A stacking approach for
building regression ensemble of single models has been studied. The results show that using stacking,
techniques, we can improve the performance of predictive models for sales time series forecasting,
