Topic modeling is a machine learning-based text mining technique that can aid scholars in automatically extracting hidden topics from large volumes of text documents. This approach is distinct from several other popular text analysis methods in the field. For instance, unlike semantic network analysis,...

semopy is a Python package for Structural Equation Modelling (SEM) with latent variables. It is open-source, distributed free of charge, simple and fast to use and has plenty of features to aid a researcher.
(TFIDF) matrix for all PDB and AF proteins, in which the terms are shape-mers and each protein is equivalent to a document. We performed topic modeling using NMF, which attempts to factorize a matrix of sizen×minto matricesWof sizen×p, andHof sizep×m. We interpret this as findingp...
We, the undersigned authors, hereby declare our individual contributions to the manuscript titled " A knowledge driven modeling formalism for automatic structural interpretation,” submitted for publication in Earth Science Informatics.1.L.I: oConceived the original approach and developed the formal interp...
Thus we developed the Python package $extbf{semopy}$ to satisfy those criteria. The paper provides detailed examples of package usage and explains it's inner clockworks. Moreover, we developed the unique generator of SEM models to extensively test SEM packages and demonstrated that $extbf{...
