Seeded-LDA for Topic Modeling

Implements the seeded-LDA model (Lu, Ott, Cardie & Tsou 2010) using the quanteda package and the GibbsLDA++ library for semisupervised topic modeling. Seeded-LDA allows users to pre-define topics with keywords to perform theory-driven analysis of textual data in social sciences and humanities (Watanabe & Zhou 2020) .
