Our emphasis was on capturing the opinion of customers, esp. consumers, wrt a given brand or product within a given industry. We chose as the context retail, which is in the midst of moving from physical stores to digital stores or perhaps their combination. The angles we chose were
Enables automated monitoring of customer opinion and its changes over time.
To measure the attitude and its change over time of consumers within some particular industry.
Ability to measure the success or failure of communication and marketing effort wrt a brand or product. Early detection of shifts in consumer opinion which might indicate quality issues or active effort by competitors.
Enables single view intuitive analysis of consumer opinion in a given industry.
Perception of the global context for business critical events wrt consumer opinion in the industry is very difficult for a global company.
Text analysis combined with intuitive visualizations for the recognition of business-relevant events:
Ability to detect early and react to threats and opportunities in the market for operative management, timely competitive intelligence about consumer opinion in B2C business, and ability to discover new ideas globally for R&D.
Enables automated cross-lingual and cross-industry detection of probably relevant emergent customer opinion trends.
Catching emergent trends in an industry, e.g. new consumer needs, are the more valuable the earlier they are detected.
Real-time statistical analysis of streaming documents for detecting deviations in content over time. This provides the ability to generate alerts based on detected deviations.
Ability to react to non-evident threats and opportunities ahead of competition.
Enables automated detection of the mode of customer movement while moving between home, work and retail stores to capture customer behavior wrt mode of transportation.
A smartphone based system is needed for detecting the current transportation mode of the user from accelerometer measurements. Developed techniques can be used to construct acceleration profiles for different vehicles, useful, e.g., in assessing vehicle types, skill level of drivers, or even fuel consumption of vehicles.
Analyzing accelerometer signals to extract movement profiles that capture characteristics acceleration and breaking patterns of different transportation modalities. By matching observed patterns against these signatures, the system can then determine the transportation modality of the user.
> 90% accuracy for separating between pedestrian and vehicular motion, and > 80% accuracy for distinguishing different vehicles / public transportation.
Enables prediction of customer movement between home, work and retail stores given the context wrt. bus ridership as an example of more detailed analysis.
Predict bus ridership as a function of time, weather, and other contextual attributes.
Predictions made using a Gaussian process regression framework.
The resulting accurate predictive models are essential, e.g., for developing on-demand transit services.
Enables support for behavioral analysis of customers in retail stores.
Enables proactive analysis of customer behavior once the customer has reached a retail store.
Pathway analytics i.e. behavioral profiling and prediction of movements of people within retail environments.
E.g. ability to promote sales based on customer preferences given product placement.
Enables powerful combination of physical store and digital content.
Gestimator: segment-based gesture recognition for complex gestures (> 95% accuracy).
Enabling retail store of the future.
