melt

As of the CRAN release of the 1.14.8 version of data.table, the
<code><a href="https://rdatatable.gitlab.io/data.table/reference/melt.data.table.html">data.table::melt()</a></code> function is not a generic. This function aims to
temporary provide a generic to this function, so that <code>melt.sentopicmodel()</code>
can be effectively dispatched when used. Expect this function to disappear
shortly after the release of data.table 1.14.9.

A framework that joins topic modeling and sentiment analysis of
textual data. The package implements a fast Gibbs sampling estimation of
Latent Dirichlet Allocation (Griffiths and Steyvers (2004)
<doi:10.1073/pnas.0307752101>) and Joint Sentiment/Topic Model (Lin, He,
Everson and Ruger (2012) <doi:10.1109/TKDE.2011.48>). It offers a variety of
helpers and visualizations to analyze the result of topic modeling. The
framework also allows enriching topic models with dates and externally
computed sentiment measures. A flexible aggregation scheme enables the
creation of time series of sentiment or topical proportions from the enriched
topic models. Moreover, a novel method jointly aggregates topic proportions
and sentiment measures to derive time series of topical sentiment.
