In this paper, we propose an LDA-based topic model for analyzing topic-sentiment evolution over time by modeling time jointly with topics and sentiments. We derive inference algorithm based on Gibbs Sampling process. Finally, we present results on reviews and news datasets showing interpretable trends and strong correlation with ground truth in particular for topic-sentiment evolution over time. %G English %2 https://hal.science/hal-01762995/document %2 https://hal.science/hal-01762995/file/icdm_short.pdf %L hal-01762995 %U https://hal.science/hal-01762995 %~ UNIV-LYON1 %~ UNIV-LYON2 %~ ERIC %~ LABEXIMU %~ UDL %~ UNIV-LYON
