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: 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.

Abstract: A computer-implemented method, system and computer program product for performing semantic matching in a data fabric. Knowledge graphs are populated with metadata enriched with master data. Based on such knowledge graphs with the metadata enriched with the master data, a trained multi-layer graph neural network generates embeddings. Furthermore, behavioral metadata from data stewards are monitored and collected. Such behavioral metadata may be used to enrich metadata, which are populated in knowledge graphs which are inputted into the multi-layer graph neural network to generate embeddings. Upon generating the embeddings discussed above, semantic matching of the data assets in the data fabric using the embeddings is performed. In this manner, semantic matching of the data assets in the data fabric is more effectively performed by utilizing master data and behavioral metadata.

Abstract: Provided is a method of repairing structures on the Lunar surface using Lunar regolith containing metallic coatings. An ultra-portable and low-pressure cold spray system is utilized to consolidate coatings. This system can be easily transported to space, reducing the payload. Lunar regolith is added to the metal powder before cold spray deposition. Lunar regolith increases the tampering effect during cold spray deposition, thereby causing severe plastic deformation of the metal powders and providing a coating with high quality and minimum porosity. The presence of Lunar regolith increases the hardness of the coating and improves wear properties. Coatings on a large area can be made rapidly without much surface preparation. These coatings can be rapidly applied to various Lunar structures to repair, reinforce, and restore (RRR) functionality and performance in the Lunar environment.

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: Records can be matched by a graph neural network model performing entity resolution on the records, and representing each record as a respective node in a graph. Record matching explanations can be generated, each record matching explanation indicating a first set of attributes, and a first set of corresponding values, used for the matching at least two of the records. Nodes can be clustered into a plurality of clusters by aggregating the record matching explanations and, based on the record matching explanations, determining which of the records have high importance values, in the first set of values, that match. At least one cluster explanation can be generated, the cluster explanation indicating a second set of attributes, and a second set of values corresponding to the second set of attributes, used for the clustering the nodes. The record matching explanation and the cluster explanation can be output.

Abstract: A computer implemented method classifies records. A number of processor units creates a training dataset comprising subgraphs of matched records matched to an entity and identifying an importance of attributes in the matched records. The matched records in a subgraph are related to each other by a subset of the attributes. The number of processor units trains a graph neural network using the training dataset. The graph neural network classifies the records as belonging to the entity.
