This research project explored the use of automatic keyword and keyphrase extraction techniques as a means to generate answers to biomedical questions. Keywords and keyphrases provide an essential way to present the topic of a given document and can help readers access core information in text. Keyword and keyphrase extraction techniques are typically used in information retrieval tasks. The purpose of this project is to select the suitability of these techniques in order to extract key concepts in training dataset of BioASQ shared task, as a first step towards achieving query-based abstractive summarisation. The outputs are measured by F1-metric to distinguish the performance of each technique.
