A few days ago, I received an email from a researcher asking if text analysis is becoming irrelevant because of AI... please read my post "AI products and text analysis methods" #quanteda #rstats

If you think the number of topics, k, is the only important parameter for topic models, you need to read this post and the research paper. I created a new model to optimize the Dirichlet priors to analyze imbalanced corpus more accurately.

In topic modeling, it is important to adjust parameters for topic sizes. If you don't know how, read this post and try the new algorithm: Looking forward to your feedback. #LDA #rstats #quanteda

You can make your R scripts for large-scale text analysis 2x faster and 3x more memory efficient using the external pointer tokens object (tokens_xptr) in new quanteda #RStats #quanteda

Does anyone know how to link to C++ header files (installed using homebrew) in R package on MacOS? #Rstat #quanteda #macOS

LSX v1.4.0 has been released with a new visualization function. The plot highlights words in an LSS model about security threats with different colors depending on their association with China, North Korea, Iran or Russia #R #quanteda

@TBroekel @marius_saeltzer @Res_Pol Replication code is

Our semantic temporality analysis recognises various temporal features beyond the tense of verbs such as adjectives, adverbs and lexical aspects. You don't need to use POS tagger or training data because it is based on semi-supervised algorithm!

RT @marius_saeltzer: New #openaccess publication in @Res_Pol. @koheiw7 and I present a new method to estimate temporal focus in text with…

@wiasnews いつも研究をサポートしてくれてありがとうございます！

日曜日の日本メディア学会の研究会で約束したとおり、種語の選び方について説明したページを作りました。

Having trouble identifying topics of sentences in large corpora? Use Distributed Sequential LDA implemented in the seededlda package. #textanalysis #nlp #rstats

@Dr_Machinavelli Very interesting. Thanks for sharing. Looking forward to reading the paper.

We can estimate emotions of words and emojis accurately using #LSS and #quanteda. If you are interested, please read our article in the J of Medical Internet Research: This is my best shot in analysis of social media.

@BoniKutela I don't think I will add network analysis functions, because there are many other packages for that. You can open a feature request about collocations on Github.

RT @NataliaUmansky: Very much looking forward to presenting part of my PhD research at the @CPH_SODAS Data Discussion next week! Thanks so…

@ste_mueller Let's discuss openly:

Users should actively participate in discussions on open source development. Otherwise, the project stall and eventually die!

Belatedly, I published instructions on how to perform Latent Semantic Scaling (LSS) using the LSX package. I hope this helps:
