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 GetSentiment API is available on the 3Scale platform. To subscribe via 3Scale, please follow these steps:
Once you've downloaded the setup file to your computer, click on it, and follow the installation instructions:
The GetSentiment API performs phrase-level sentiment analysis: it detects terms (key phrases and entities) in each sentence and recognizes sentiment associated with each term. To achieve that, it uses proprietary classifiers and lexicons. To customize them to a new domain (industry or vertical, such as finance, retail, hospitality), the system accepts user-supplied lexicons that extend and override the default functionality.
