Siemens – Natural Language Query
Saving $10m per year
Siemens increase sales and reduce service costs through Natural Language Queries of complex, heterogeneous enterprise data
Deployment of USI Answers will save us nearly $10 million dollars this year. We have been able to lower the initial new user training time by more than 50 percent as well as increase efficiency by gaining actionable insight in our data by users across 18 countries.

Their Goal
Provide a system to allow untrained users who have no knowledge of the underlying information sources to get answers to complex domain-specific questions using natural language.
Their Challenges
- Poor meta-data
- Data sources: Dozens of internal and external sources are needed
- Natural language query processing with an understanding of the domain-specific dictionaries, synonyms, line-of-business and region of business specific abbreviations, and shorthand notation.
- Structured and un-structured data
- Data growth – 800% annually growth in information
- Real-time response to queries – 0.8 seconds
The Solution
The queries include semantic technology for contextual inferred understanding – for example “show me all active units in the a/p region” requires a contextual understanding of what the ‘units’ are, in this case generators and also to know the business users abbreviate the Asia Pacific region as ‘a/p’. A significant design goal to meet user expectations of responsiveness was to provide answers in less than 1 second regardless of complexity of the query or span of database sizes and locations
