摘要:	Recruitment is an essential function of Human Resources. Finding an appropriate hire is crucial to the organization. Understanding a candidate’s personality can be useful to the hiring process as employers can have an idea of whether the candidate fits the role and culture. The arrival of the internet and social media has brought large changes to recruitment, but they also bring new opportunities. Social media such as Twitter, Facebook and Reddit allow employers to market themselves to potential employees and candidates can engage directly with employers. These engagements produced a lot of text content which can be analyzed to find out more about candidates as it is possible to capture some aspects of their personality through their use and style of language. This research aims to apply machine learning and deep learning techniques to Reddit text data on the Five-Factor Model. The research will compare ten machine learning classifiers and six deep learning classifiers which includes two transformer models with our proposed sentence selection method and deep learning model architecture, FF-BERT. Our proposed method will utilize Log-Likelihood Ratio to extract keywords from the high and low end of each personality dimension and combine them to create a list of keywords which will be used to extract the most relevant sentences for the five personality dimensions which will be used for training. We also performed Topic Modeling using BERTopic and compared the results with keywords from each personality dimension. Our results showed that the proposed sentence selection method and deep learning architecture was able to achieve substantial gains compared to the machine learning and deep learning techniques. We also found some patterns within the topics extracted by BERTopic and keywords which match some characteristics of the personality dimensions.
