As software becomes increasingly integral to daily life, software companies must address a broad range of queries from users, particularly in forums. In open source software communities, users often pose questions that include difficulties, propositions, and opinions. To manage these effectively, constructing a Frequently Asked Questions (FAQ) document is a common strategy. An FAQ helps reduce repetitive questions and saves time for forum members by providing answers to frequently asked questions. This study introduces a pioneering, semi-automatic FAQ finding process designed to help forum managers construct effective FAQs. The approach is evaluated through two case studies, demonstrating its effectiveness in improving FAQ construction.
