Several topic analysis tools based on latent dirichlet allocation (lda) have been proposed to analyze information stored in software repositories to model software evolution, thus helping software stakeholders to be aware of the focus of development efforts at various time during software evolution previous lda- based.
Much literature is devoted to topic evolution in finite document sequences assuming a fixed vocabulary in this study, we propose “topic monitor” for the monitoring and understanding of topic and vocabulary evolution over an infinite document sequence, ie a stream we use probabilistic latent semantic analysis (plsa.

To conduct topic evolution analysis, we employ three major procedures, and for each procedure, we develop the following novel technique: the markov random field-based topic clustering, automatic cluster labeling, and topic similarity based on within-period cluster similarity and between-period cluster. Thus, according to this so-called selectionist theory, nonadaptive processes were at best minor contributors to evolution however, the analysis of sequence data that became available in the late 1960s considerably challenged this view in 1968, these empirical data and new theoretical developments led motoo kimura to.

Allocation (lda)  for analyzing the evolution of topics along time [2, 28, 11, 27] social information for topic detection has masqueraded with many names in literature there have been entire lines of works which use the link structure between documents to model topics this link structure can be built to model a certain.
In this paper, we focus on the visualization of the co-evolution of terms in tweets in order to facilitate the analysis of the evolution of topics by a decision-maker we take advantage of the perceptual quality of heatmaps to display our 3d data ( term x time x score) in a 2d space furthermore, by computing an appropriate order. Co-word analysis for the preliminary exploration of research foci and developmental trends in psychiatry is helpful in finding developmental rules, choices of topics, and innovative research our study had some limitations in the future, we should expand our research scope and use a variety of research.
