Identifying if the sentence if it comprise information about education
I think what you are looking is to differentiate between 'be' and 'BE' based on context. Word2Vec is a good place to start but to determine the difference between words based on contexts is 'Sense2Vec.' Word Sense Disambiguation paper is worth to look at. I am not sure if this is what you're looking for because if you have 'be' in every sentence which is most likely, then this won't be an ideal solution. You might have to do some extra data preprocessing like changing 'be' to 'Bachelor of Engineering' based on your sentence.
