Opinion Extraction From Customer Reviews

Submitted Nov 13, 2016

When a review or a social media post talks about a product or service, the user might want to discuss multiple aspects or sub-topics related to the product or service.
For example, when a customer buys a laptop from Flipkart,the customer might have good things to say about the sound quality of laptop but he/she might be disappointed with the service offered to him/her by vendor and therefore might think that the Delivery Model needs to be revamped.
So a general sentiment analyser which is normally used might turn trivial for the overall sentiment drawn towards the product/service and hence might not be able to capture the full essence of the actual product.
My talk shall be about a need as well as implementation of improved Aspect-based Sentimental Analyser/Opinion Extraction for better and more fine-grained analysis of user feedback, which would enable service providers and product manufacturers to identify the certain business aspects that needs improvement.
