keyATM 0.5.4
- Adding the
refine_keywords() function to refine
keywords by dropping topics that do not have any occurrence in the
documents (#222)
keyATM 0.5.3
Bug fix
- Fixing the semantic coherence function (#220)
keyATM 0.5.2
Minor changes
- Updating the paper information
- Deleting the
save() function (thank you @AMindToThink for repoting this
error in #214)
keyATM 0.5.1
Minor changes
- Adding options to set the hyperparameters
eta.
- Documentation updates to pass CRAN checks.
keyATM 0.5.0
Major changes
- Migrating to C++17 to follow the
new CRAN check. We edited
shuffled_indexes() that
internally used std::random_shuffle(). This change does not
guarantee backward compatibility across all platforms.
- Using the package
cli instead of the base R
message() and warning() functions.
- A new feature to resume the iteration.
- Stopped support for the
label model in
keyATM() (it was an experimental feature).
Minor changes
- Supporting tidyselect
1.2.0. Updating some internal functions.
- Including the state information of HMM in the
plot_timetrend() output (thank you @WenHanGao for the suggestion in #188).
Bug fix
- A bug fix in
summary.keyATM_docs().
keyATM 0.4.2
Major changes
- Adding the
plot_topicprop() function.
- Implementation of semantic coherence diagnostics from Mimno et
al. (2011) via the
semantic_coherence() function (thanks to
Seo-young Silvia Kim for your suggestion).
Minor changes
- Pure R text loading to address issues related to UTF-8 encoding in
Windows (#189)
keyATM 0.4.1
Minor changes
- Remove an unused argument (
width) in the
plot_timetrend() function.
- Use
Rcpp::message() if
verbose = TRUE.
- Completely remove
parallel::mclapply.
Bug fix
by_strata_DocTopic() takes the correct arguments (#180, thank you
@pmeiners for reporting this!).
keyATM 0.4.0
Major changes
- Implementation of Polya-Gamma covariate keyATM.
- Use
future.apply instead of parallel (no
backward compatibility if you use the init_parallel
option).
- The
keyATM_read() function returns a list of objects
(e.g., text and document index).
- An option to store document names in a quanteda dfm object. The
keep_docnames option in the keyATM_read()
function (thank you Morgan
‘Les’ DeBusk-Lane for the suggestion!).
- An option to split a dfm to choose keywords with an unsupervised
topic model.
Bug fix
- Using just first 58 speeches of inaugural corpus in test (thank you
Ken Benoit for catching
this!).
keyATM 0.3.1
Major changes
- Changes related to release of dplyr 1.0.1.
keyATM 0.3.0
Major changes
- Use the Highest Density Interval as a default
(
method = "hdi") in plot.strata_doctopic(),
plot_timetrend(), and plot_pi(). The previous
version uses the Equal-tailed Interval
(method = "eti").
- Add
read_keywords for reading dictionary files
(e.g. YAML, LIWC).
- Add the
predict() function for the covariate keyATM
(thank you Sanja
Hajdinjak for the suggestion!).
- Detailed options for standardization in the covariate keyATM:
- The
standardize option in model_settings
argument of the keyATM() function now takes one of
"all", "none", or "non-factor"
(default).
"all" standardizes all covariates (except the
intercept), "none" does not standardize any covariates, and
"non-factor" standardizes non-factor covariates.- In previous versions, this option takes either
TRUE
(default, standardizing all covariates) or FALSE.
- A bug fix in the
by_strata_DocTopic() function.
- The output of the
keyATM() includes the index of
documents used for fitting (this will be useful if the input includes
documents with zero length).
- Add a
progress_bar option in the
keyATM_read() function (thank you Jae Yeon Kim for the
suggestion!).
Bug fix
- Fix checking time index input (thank you Jae Yeon Kim for pointing out this
issue!).
keyATM 0.2.2
Major changes
- Updates for dplyr 1.0.0.
- Update tests.
keyATM 0.2.1
Major changes
- Temporary update
test-Initialization.R to deal with
some errors.
keyATM 0.2.0
Major changes
- Update the
by_strata_DocTopic() function.
- Make examples runnable (thank you Chung-hong Chan for the
suggestion!).
- Speed up (about 15% faster).
save_fig() function.- Automatically drops documents with length 0, raising a warning
(thank you Francesco
Grossetti for the suggestion!).
- Update
plot.strata_doctopic(): showing by topic by
default (thank you Soichiro
Yamauchi for the suggestion!).
Bug fix
weightedLDA() without specifying the number of
iterations (Chung-hong
Chan independently reported this bug, thank you!).- Log-likelihood of dynamic models.
- Saving figures
- Topic labels when there is no keyword topic.
summary.strata_doctopic(): the last topic is removed
when the number of no-keyword topic is 0 (thank you Emma Ebowe
for pointing out this issue!).
keyATM 0.1.0
Major changes
- The first CRAN version.

Olivella for finding several bugs!
