March 8, 2022(NLP) Best practices for topic modeling and generating interesting topics?
My team and I have recently released a python library called OCTIS ( https://github.com/mind-Lab/octis ) that allows you to automatically optimize the hyperparameters of a topic model according to a given evaluation metric (not log-likelihood). I guess, in your case, you might be interested in topic coherence. So you will get good quality topics with a low effort on the choice of the hyperparameters. Also, we included some state-of-the-art topic models, e.g. contextualized topic models ( https://github.com/MilaNLProc/contextualized-topic-models ). Other comments based on my personal experience with topic models: Preprocessing is really important and can affect your final results. I usually remove stop-words, numbers, most frequent words (which are usually domain-related but do not convey much information), and the less frequent words. I also lemmatize and remove documents with few words. But in general, it depends on your domain. Some of the topics may be junk topics. Some researchers do not consider them to evaluate the topic quality. There are some metrics that allow you to rank the topics by their importance. See for example the paper "Topic Significance Ranking of LDA Generative Models " by AlSumait et al.: https://mimno.infosci.cornell.edu/info6150/readings/ECML09_AlSumaitetal.pdf It seems that topic interpretability != topic coherence, as this very recent paper suggests: https://www.aclweb.org/anthology/2021.naacl-main.300/ But still coherence is a good indicator and unfortunately, we usually don't have the resources to make a human evaluator annotate each topic according to its interpretability.

7. Extracting Information from Text
Chunkers can be constructed using rule-based systems, such as the RegexpParser class provided by NLTK; or using machine learning techniques, such as the ConsecutiveNPChunker presented in this chapter. In either case, part-of-speech tags are often a very important feature when searching for chunks. Although chunkers are specialized to create relatively flat data structures, where no two chunks are allowed to overlap, they can be cascaded together to build nested structures. Relation extraction can be performed using either rule-based systems which typically look for specific patterns in the text that connect entities and the intervening words; or using machine-learning systems which typically attempt to learn such patterns automatically from a training corpus.

November 17, 2025 - Classification-based IE is a 2-step process that approaches information extraction as a supervised learning classification task. First, machine learning models are trained on labeled datasets to learn the connections between entities and their corresponding attributes. The models then predict labels for the entities they identify in new unstructured data. Sequence labeling is the cornerstone of NLP and uses deep learning models to identify and label the components of an input sequence—for example, the words in a chatbot prompt.
