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.

Abstract: A method, system, and computer program product for managing communication privacy in a conversation system are provided. The method detects an utterance on a public channel by a user of a computing device. A privacy nature of the utterance is determined. Based on the privacy nature, a classification confidence is determined for the utterance. The method generates a privacy question to be presented to the user based on the privacy nature and the classification confidence. In response to a confirmation response, a privacy channel is established. The method switches from the public channel to the privacy channel.

Abstract: Foams and methods of fabricating and using the same are provided. The foams can be three-dimensional (3D), free-standing, and/or rigid and can be used as, for example, nanofiller networks. The shape and size of the foam pore interconnected network can be tailorable/tailored. The foams can be, for example, hybrid one-dimensional (1D)/two-dimensional (2D) foams of 1D and 2D materials (e.g., hybrid boron nitride nanotube (BNNT)/boron nitride nanoplatelet (BNNP) foams). A freeze-drying-based method can be used to fabricate bulk porous foam, which can be used for, e.g., nanofiller for polymer nanocomposites.
