To demonstrate one possibility, we created an application that collects and analyzes people's mentions of visits to restaurants, on various social media sites, discussion forums, and travel sites. The application uses two API services: Webhose to collect relevant restaurant mentions and GetSentiment to analyze them in terms of sentiment and topical categories.
The application is available here. Under the hood, the system calls Webhose API several times a day, to retrieve freshly indexed mentions of restaurants, cafes, bars, bistros and pubs. Relevant text snippets are then extracted and submitted to GetSentiment API, which returns a list of domain topics found in a snippet as well as the sentiment score associated with each topic. The demo page shows the name of the restaurant, the text of the snippet, identified topics and sentiment, as well as a link to the original publication site.
