[…] of a multivariate normal random variable, allows for a general pattern of variability between the components of the distribution []. more specifically, the ctm contained in the r package topicmodels [] was the method used for the construction of the ctm in every iteration., for each one of the individuals of the population, its set of k-mers, along with the original set of sequences, […]

[…] for the sequence of random variables (see ). the sampling algorithm is applied to the chain to sample from the limited distribution, and it approximates the posterior (see ) []., we employed the topicmodels package in r [] to model the strategy texts. the tm package was also extensively employed for text preprocessing and converting the corpus to the document-term matrix []. in our analysis, […]

[…] text mining. the r package “tm” (feinerer et al. ) provides basic text mining functionality and is used by a rapidly growing number of higher-level packages, such as “rtexttools” (jurka et al. ), “topicmodels” (grün and hornik ) and “wordcloud” (fellows ). similarly, there are many toolkits and frameworks for text mining in java that could also be called from within a taverna workflow.

[…] their words. then the lda algorithm is used in order to infer the probabilistic topic model for a fixed number of topics t. in this work we used the lda implementation provided by the r package topicmodels []. the lda model, defined as in section methods, is fitted using gibbs sampling [] and considering parameter values as suggested in []. given a fitted topic model, it is possible […]
