Features of the Service

Accurate Analysis

This service uses AI technology to analyze a variety of text data from social media, customer reviews, and business data. The service classifies the results into three major emotional categories (positive, negative, and neutral). The text data can then be further broken down into more detailed sentiments (joy, happiness, love, etc.). The service can also classify text into different categories (related to vehicles, food, sports, etc.).
Hitachi provides unique filtering and tagging technology to improve data visualization of the analysis results.

Insightful Viewer

To use sentiment data for your business, you must be able to quickly and easily find the data you want. To achieve this, this service's dashboard has three features to help you notice important points. First, the dashboard displays analysis data in various graphs (pie chart, timeline, word ranking, etc.). Second, the dashboard can filter analysis data not only by keywords and dates, but also by emotions and topics categorized by AI. Finally, the dashboard can also filter analysis data by tags set by users.

Easy Maintenance

Through the machine learning of highly relevant words and technical terms contained in collected data, the AI automatically updates the refining conditions used for the filtering dictionary. This makes it possible to maintain and improve the accuracy of search refinement without additional maintenance work.

Hitachi's Sentiment Analysis Service is available in a default service package or customized systems to meet your needs.
Data from Twitter and Pantip (Thai only) is supported for analysis in the default plan.
