Bien que #Rstats soit le cousin pauvre de #Python en traitement de texte (#NLP), rien n'empêche de l'utiliser pour la modélisation thématique (#topicmodelling).

Dans cet exemple, je montre aussi comment soumettre le résultat de l'analyse à une #IA textuelle générative basée #LLM.

Corpus de test: littérature française de la seconde moitié du 18e. Quelqu'un m'expliquera peut-être l'étrange mais quantifiable proximité entre Voltaire et le Marquis de Sade...

Curious about #TextAnalysis? Do you want to be able to discuss the differences between #CorpusLinguistics and #DataScience? In this #TrainingTuesday resource from #DiMPAH and #DARIAHTeach, learn how to apply text analysis techniques, such as #SentimentAnalysis and #TopicModelling, to a dataset:

Would anyone have some example code on how one would approach to do #semisupervised #topicmodelling with #BERTopic on a dataset of articles and book-length documents in order to do document-level #classification and analyses? I am interested in analyzing how document topics change over time.

@dajb Though I’m still sore from the overwhelming LLM chatter of the past few months, I did think about them while reading your piece…
Had neat experiences with other AI/ML approaches to classification. (#TopicModelling methods such as #LatentDirichletAllocation.)

For collaborative design, it does sound like nonhuman actors can contribute. Was also thinking about the iterative nature of design approaches. And about fluid categories.
As we say in #LinguisticAnthropology:

One week in Mastodon, a good feel, seems great for geeking about #geospatial #geoviz #dataviz #coding.

I would like to connect further with people in #NLP #NaturalLanguageProcessing #NLPTransformers #TopicModelling #BERTopic.

Also I would like to connect with #Geospatial people in #Australia.

Pass me a follow 🤓👋
