Abstract: Systems and methods are provided for acquisition of acoustic emission during indentation. An acoustic transducer can be used during indentation of a sample to acquire AE and capture valuable information concerning internal structural changes occurring within the material of the sample during the indentation process. This can help determine and/or understand the deformation characteristics and/or bulk plastic properties of the material of the sample. The transducer can be either a contact type acoustic transducer or a non-contact type acoustic transducer.

Abstract: Generating a semantic synopsis is provided. A dataset comprising structured data is received and semantic analysis of the dataset is performed to determine categories of information included in the datasets. A spatio-temporal analysis of the dataset is also performed to determine time periods and locations to which the dataset applies. A static synopsis of the dataset is then generated in natural language sentences that describes semantic information in the dataset and time periods and locations covered by the dataset. The synopsis can be customized according to a user role and search query data.

Abstract: Embodiments of the present invention provide an approach for exploring interesting data patterns in structured tables through recommending aggregate questions in a conversational data exploration. Specially, interesting features and operators are selected that are used to frame aggregate questions based on user intent and the data. The aggregate questions are ranked based on user persona and interestingness of the questions. The approach dynamically adapts and improves the recommendation of interesting and relevant aggregate questions for the user based on user feedback iteratively.

Abstract: Various systems and methods are presented regarding implementing one or more capabilities into a dialog flow occurring at an automated interface (e.g., a chatbot). A capability can be invoked at the interface in accordance with a user's requirements, e.g., the capability is a function to review data. An application programming interface (API) can be generated from the capability, wherein the API has features, parameters, metadata, etc., generated based on those of the capability. The API can be incorporated into a dialog, wherein the dialog can be subsequently presented on the interface (e.g., as part of a dialog flow). Interaction between the user and the dialog can cause the capability to be executed. Based upon the API features, etc., the API can be incorporated into a dialog, for example, by cloning a dialog, appending a dialog with the API, replacing a pre-existing API with the API in a dialog, and suchlike.
