In the previous article, I introduced the concept of topic modeling and walked through the code for developing your first topic model using Latent Dirichlet Allocation (LDA) method in the python using Gensim implementation.. Pursuing on that understanding, in this article, we’ll go a few steps deeper by outlining the framework to quantitatively evaluate topic. -

In this post I will go over installation and basic usage of the lda Python package for Latent Dirichlet Allocation (LDA). I will not go through the theoretical foundations of the method in this post. However, the main reference for this model, Blei etal 2003 is freely available online and I think the main idea of assigning documents in a corpus (set of documents) to latent (hidden) topics based on a vector of words is fairly simple to understand and the example (from lda) will help to solidify our understanding of the LDA model. -

Latent Dirichlet Allocation (LDA) is one such technique designed to assist in modelling the data consisting of a large corpus of words. The LDA is based upon two general assumptions: - Documents that have similar words usually have the same topic - Documents that have groups of words frequently occurring Now, its finally time to grab the highest probable words for the clustered topics. we will get a group of words that when in group. before this, let us familiarize our-self the concept of argsort() argsort() in Python. numpy. argsort() function is used to perform an indirect sort along the given axis. -

Latent Dirichlet Allocation (LDA) is a algorithms used to discover the topics that are present in a corpus. A few open source libraries exist, but if you are using Python then the main contender is Gensim. Gensim is an awesome library and scales really well to large text corpuses. The structure of the resulting matrices returned by both NMF and LDA is the same and the Scikit Learn interface to access the returned matrices is also the same. This is great and allows for a common Python method that is able to display the top words in a topic. Topics are not labeled by the algorithm — a numeric. -

Latent Dirichlet allocation is one of the most popular methods for performing topic modeling. Each document consists of various words and each topic can be associated with some words. The aim behind the LDA to find topics that the document belongs to, on the basis of words contains in it. It assumes that documents with similar topics will use a similar group of words..
