I'm looking for an expert in a field of NLP, Data Science, Machine Learning who could help me with the following task: - I have 1M textual documents (title, body, author) - To cluster similar documents together - To create a single title for a cluster - To perform sentiment analysis over the whole cluster (or to sum up sentiments of all articles within the cluster?) All of tasks above needs to be made in a way so we can feed these data to backend service and then feed to application (using elasticsearch?). Basically, think about it as we are trying to make another Google News ([login to view URL]) - I need to know how to accomplish these tasks - What is the best technology stack to create easy data service for simple REST backend

Hi, You are looking to use NLP and machine learning to create a newsfeed. I can assist you to cluster the articles to determine their categories and perform sentiment analysis per category to create a trend of overall sentiment with time using R. The outcomes will then be integrated with the backend for display or farther processing. Regards, Chris

Hi! Considering the size of your database, I suggest making a recommender based on nearest neighbor search. This involve training a neural net to classify documents, then use it to extract encoding for each document. The encoding is represented as float arrays, and is used to cluster the dataset. This approach is only applicable to small dataset (around 1m to 2m documents). If you want this app scalable, we might have to think about another approach.

We are a team of senior data scientists with background in statistics and computer science with more than 10 years of experience in the domain of textual analysis and text mining. SAS is the platform that we use for the implementation of projects of this nature by writing actual code and exploiting specific modules available on sentiment analysis. Volume is not an issue for us, as we are familiar with processing of large volumes of structured/unstructured data. Our methodological approach focuses on the following pillars: Profiling of textual data for quality assurance, Data cleansing from non relevant characters/strings, Dictionary creation , Keyword generation , Application of similarity algorithms for finding matching among different strings or the content of textual fields, Model application for Clustering, Validation of the model Our portfolio includes a series of successfully implemented projects in the field of text mining and we would be happy to add one more in the list!
