An embodiment includes identifying metadata attached to a first node of a graph, where the metadata satisfies an ontological condition. The embodiment also includes transforming the graph such that the transforming results in the graph having a new graph structure, where the transforming of the graph comprises removing the metadata from the first node and adding a second node representative of the metadata removed from the first node to the graph such that the second node is connected to the first node by a first edge.

Metadata decomposition for graph transformation

Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining first building event transaction data of a building using a first data source; recording a first blockchain block in a blockchain ledger, the first blockchain block having a timestamp and the first building event transaction data; obtaining second building event transaction data of the building using a second data source; recording a second blockchain block in the blockchain ledger, the second blockchain block having a timestamp, and the second building event transaction data; examining data of the first blockchain block and the second blockchain block; and providing one or more output in dependence on the examining.

Blockchain based building action management

A data item block is linked to a construction item block in a blockchain representing a construction project. A multi-dimensional tensor is constructed from a set of blocks in the blockchain, the set of blocks including the data item block, the construction item block, a block describing an operation relative to the construction item of the construction item block. An event is forecasted along a dimension of the tensor. The event is of the dimension, and is likely to occur relative to the construction item at a future time. A determination is made whether the event complies with a specification included in a spec block of the blockchain. When the event is non-compliant, an exception block corresponding to the event is linked with the construction item block in the blockchain.

Blockchain enabled quality control in construction projects

Embodiments described herein provide approaches for validating synonyms in ontology driven natural language processing. Specifically, an approach is provided for receiving a user input containing a token, structuring the user input into a semantic model comprising a set of classes each containing a set of related permutations of the token, designating the token as a synonym of one of the set of related permutations, annotating the token with a class from the set of classes corresponding to the one of the set of related permutations, and validating the annotation of the token by determining an accuracy of the designation of the token as a synonym of the one of the set of related permutations. In one embodiment, the accuracy is determined by quantifying a linear distance between the token and a contextual token also within the user input, and comparing the linear distance to a pre-specified linear distance limit.

Contextual validation of synonyms in otology driven natural language processing

Systems and methods for automatic targeted illumination based on aggregate illumination from multiple light sources are disclosed. In embodiments, a method includes: determining, by a computing device, a localized area of a defined physical location based on received location information; determining, by the computing device, a desired level of brightness for the localized area; calculating, by the computing device, an illumination level at the localized area based on current illumination levels of lighting devices within the defined physical location and locations of the lighting devices within the defined physical location; generating, by the computing device, instructions to effect a change in one or more of the lighting devices, wherein the change in the one or more lighting devices results in the desired level of brightness for the localized area; and sending, by the computing device, the instructions to at least one controller of the one or more lighting devices.

Automatic targeted illumination based on aggregate illumination from multiple light sources

During a live stream of a main content to a user, a biometric response of the user is measured during a first streamed portion of the main content. The biometric response is analyzed to detect an event in the first streamed portion of the main content. The biometric response of the user during the event indicates that the event is a user-specific climactic event. Based on the analysis, a user-specific set of feature values is computed that are representative of the user-specific climactic event in the first streamed portion of the main content. A user-specific non-climactic period is forecasted in a future portion of the live stream during which a likelihood of an occurrence of any user-specific climactic event is below a threshold likelihood. A secondary content is inserted during the user-specific non-climactic period.

Individualized dynamic insertion of secondary content in live streaming

Embodiments selectively present of virtual reality device content in response to the excitement of monitored persons. Thus, processors are configured to link a user's virtual reality system to a biometric sensor that acquires biometric data from a monitored person, wherein the virtual reality system is presenting immersive sensory content to the user, and the monitored person is viewing alternative content that is different from the immersive sensory content presented to the user. Processors configured according to the present invention determine whether the monitored person is currently in a threshold state of excitement as a function of biometric data acquired by the biometric sensor; and in response to determining that the monitored person is currently in the threshold state of excitement, automatically switch content presented by the virtual reality system to the user to the alternative content viewed by the monitored person.

From a directional acyclic graph (DAG) corresponding to a data volume, a matrix of relationships of a first node and a second node is computed. The DAG includes a set of nodes and a set of directional edges, the set of nodes including the first node and the second node. An inverted matrix is computed from the matrix, which retains values in only those column positions where a value in a first row corresponding to the first node is opposite of a value in a second row corresponding to the second node. From the first row, a first cluster of nodes related to the first node is constructed by selecting nodes corresponding to those columns where the first row has a value indicating an affirmative relationship. Information representing the first cluster of nodes a second cluster of nodes are output.

Detecting clusters and relationships in large data sets

A method, system, and computer program product for identifying related information in dissimilar data are provided in the illustrative embodiments. Using a first part of a first entry in a dictionary, a first portion is identified in a first data, the first part matching the first portion within a tolerance. A second part of the first entry referencing a section of a second data is determined, the second data being organized in a repository according to a schema. A third part of the first entry sufficient to locate a record in the section of the second data is determined. A query is constructed using the second part and the third part, and performed on the second data. A result set is obtained, wherein a record in the result set is related to the first portion in the first data and the record does not include the first portion.

Identifying related information in dissimilar data

Systems and methods for autonomic positioning of overlays within streaming data are disclosed. In embodiments, a computer-implemented method comprises: providing a hosted data stream containing a first display object to a plurality of participants through respective participant devices; providing a hosted second display object to the plurality of participants through the respective participant devices, wherein the second display object is contained within an overlay that is positioned atop the first display object at a first position; calculating consensus coordinates for the second display object based on suggested position data received from the respective participant devices; calculating customized coordinates for the second display object for each of the respective participant devices based on the consensus coordinates and participant data; and sending the customized coordinates to each of the respective participant devices.

Autonomic positioning of overlays within streaming data

From a live streaming of a main content, an already streamed portion of the main content is analyzed to identify an occurrence of a climactic event in the main content. Based on the analysis, a set is constructed of feature values that are representative of the climactic event in the already streamed portion of the main content. A non-climactic period is forecasted during which a likelihood of an occurrence of any climactic event is below a threshold likelihood. A secondary content is inserted in the live streaming of the main content during the non-climactic period, such that a likelihood of the secondary content insertion interrupting the live streaming during a second climactic event is less than a second threshold of likelihood. The live streaming of the main content is continued after the secondary content is completely transmitted in the live streaming.

Intelligent insertion of secondary content in live streaming

A non-climactic period is forecasted during a live streaming of a main content, where a likelihood of an occurrence of any climactic event in the non-climactic period is below a threshold likelihood, and where a second content is inserted during the non-climactic period. A validation is requested from a first user of the live streaming, of the forecasted non-climactic period and a first response to the request is received from the first user. Based on the first response, a first rank of the first user is computed relative to another user in a group of responding users. A first dynamic delay period that has an inverse relationship with the first rank is computed for the first user. A first transmission of a future portion of the live streaming to the first user is delayed by at least the first dynamic delay period.
