About the EventOver the past decade research and applications of topic models have exploded, paving the way for new types of analyses of text data. Topic models discover latent concepts and themes in text corpora relying on unsupervised learning, allowing applications to a diverse set of corpora. However, topic is only one aspect of many that can influence text and data analysts are often interested in others: sentiment, perspective, aspect, etc. |
