...Note that we could take a LDA [2] type approach on the tweets extracted based on string matching to .nd other tweets with similar latent topical distribution which would be a more comprehensive corpus for the given topic....

...The notable exception is TwitterRank, proposed by Jianshu et al. [20], which computes the topical distribution of a user based on Latent Dirichlet Allocation [2] and constructs a weighted user graph where edge weight indicates the topical similarity of the two users....

...Furthermore, few evaluations have used the same metrics to compare distinct approaches such as Latent Dirichlet Allocation (LDA) (Blei et al., 2003), Latent Semantic Analysis (LSA) (Landauer and Dutnais, 1997), and Non-negative Matrix Factorization (NMF) (Lee and Seung, 2000)....

...For example, existing studies [19, 35] make use of the text description in each task and adopt topic model techniques [6, 56] to generate a vector of sizeK for the task; while Multi [51] learns aK-size vector without referring to external information (e....

...We completed our retrieval of relevant and recent studies by checking Google Scholar and also revisiting basic literature on topic modeling (e.g., Blei, 2012; Blei et al., 2003)....

...Enhancing interpretability and reliability with regularization techniques The seminal model proposed by Blei et al. (2003) is based on the idea that the clustering effect of the algorithm works well, even if the initial assignments for θ and ϕ are set completely at random....
