The workflow scrapes reviews, preprocesses text with regex and tokenization, scores sentiment using the SentiLexM lexicon (designed for Malay/English code-switching), geocodes establishments, and renders an interactive WebGIS heatmap using Folium deployed on Netlify. Key findings show positive sentiment clusters around transit-connected central city areas, with applications in commercial real estate and urban planning. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I combine sentiment analysis with GIS to visualize sentiment hotspots on a map? Scrape reviews (e.g., from Google Maps), clean the text with regex to remove URLs, punctuation, and casing noise, then score sentiment using a lexicon like SentiLexM that handles local slang and code-switching. Geocode each review location, then feed latitude, longitude, and sentiment score into Folium's HeatMap plugin to render an interactive Kernel Density Estimation hotspot map, deployable as static HTML on Netlify. _Developers building similar geospatial sentiment pipelines can find related Python and GIS workflows on daily.dev._ ### Why would I use a lexicon like SentiLexM instead of a standard English sentiment dictionary? Standard English sentiment dictionaries often fail to correctly score reviews containing local slang or code-switching between languages, such as Malay and English mixed in the same sentence. SentiLexM is a lexicon dictionary designed to account for this local context, assigning emotional weights to words while accounting for regional dialect and slang that off-the-shelf analyzers misinterpret. _Anyone choosing a sentiment lexicon for multilingual text can compare approaches like this on daily.dev._ ## Similar posts on daily.dev - [Learning Word Vectors for Sentiment Analysis: A Python Reproduction](https://daily.dev/posts/learning-word-vectors-for-sentiment-analysis-a-python-reproduction-nyqjhg15a) · Towards Data Science · 0 upvotes · 0 comments - [Building an End-to-End Sentiment Analysis Pipeline with Scikit-LLM](https://daily.dev/posts/building-an-end-to-end-sentiment-analysis-pipeline-with-scikit-llm-dh45aqfbd) · Machine Learning Mastery · 2 upvotes · 0 comments - [Say What You See: Building Multimodal Content Signals at Scale](https://daily.dev/posts/say-what-you-see-building-multimodal-content-signals-at-scale-jm8ils033) · agoda · 0 upvotes · 0 comments - [Google is using old news reports and AI to predict flash floods](https://daily.dev/posts/google-is-using-old-news-reports-and-ai-to-predict-flash-floods-ke3nuswgu) · TechCrunch · 1 upvotes · 0 comments - [R-bloggers](https://daily.dev/posts/r-bloggers-gbvr8pfmr) · R-bloggers · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#nlp](https://daily.dev/tags/nlp), [#sentiment-analysis](https://daily.dev/tags/sentiment-analysis), [#gis](https://daily.dev/tags/gis) [View this post on daily.dev](https://daily.dev/posts/mapping-public-sentiment-gis-hotspot-analysis-of-trendy-spots-in-kuala-lumpur-ccqvycodr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Mapping Public Sentiment: GIS Hotspot Analysis of Trendy Spots in Kuala Lumpur","url":"https://daily.dev/posts/mapping-public-sentiment-gis-hotspot-analysis-of-trendy-spots-in-kuala-lumpur-ccqvycodr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/mapping-public-sentiment-gis-hotspot-analysis-of-trendy-spots-in-kuala-lumpur-ccqvycodr"},"datePublished":"2026-07-23T03:09:36.742Z","dateModified":"2026-09-14T07:38:29.082Z","description":"A Final Year Project that builds an end-to-end Python pipeline to map public sentiment from Google Maps reviews across Kuala Lumpur.
