Discovering topics in text datasets by visualizing relevant words
This addresses the need for efficient content overview in text analysis, but it is incremental as it combines existing clustering and visualization techniques.
The paper tackles the problem of quickly summarizing large document collections by identifying topics through clustering and visualizing distinguishing words for each topic, demonstrating the approach on New York Times article snippets.
When dealing with large collections of documents, it is imperative to quickly get an overview of the texts' contents. In this paper we show how this can be achieved by using a clustering algorithm to identify topics in the dataset and then selecting and visualizing relevant words, which distinguish a group of documents from the rest of the texts, to summarize the contents of the documents belonging to each topic. We demonstrate our approach by discovering trending topics in a collection of New York Times article snippets.
