One example provides, on a computing device, a method comprising iteratively receiving, from one or more collaborative communications applications, user data comprising communications of a user, analyzing the received user data to extract contextual information regarding the user, and sending the contextual information to a contextual information data store for the user. The method further comprises receiving a search query originating from within the collaborative communications application, parsing the search query to identify a referential search term, querying the contextual information data store for the user with the referential search term to identify previously stored contextual information regarding the user associated with the referential search term, and sending the previously stored contextual information identified to the collaborative communications application from which the search query was received.

Contextual search in collaborative communications applications

Representative embodiments disclose mechanisms to assign search results associated with a user query to locations based in part on features associated with the user's Internet of Things (IoT) devices. This results in a search page that presents results in an order and prominence that improves user understanding and information accessibility. Features from IoT devices are used to train a machine learning model that receives as an input information from an IoT entity index, the query, and results from the search engine along with their static rankings. The resultant IoT positioning scores are used to assign an initial location on the search results page. A second machine learning model trained using IoT features is then used to assign a final location on the page. The system causes display of the page to the user.

Personalized whole search page organization and relevance

Techniques for providing a recommendation engine for personal digital assistant functionality on hardware devices. In an aspect, sensor data and other signals for a user are collected and processed to extract user patterns. A user profile is further constructed using machine learning techniques. The insights obtained from the user patterns and user profile are combined by digital service routines to generate customized recommendations for users. In a further aspect, user feedback may be utilized to improve the accuracy and relevance of the recommendations.
