A method and a system for preserving privacy of a dataset are provided. In the method, a k-anonymity value with respect to a sensitive data field is determined according to at least one first quasi-identifier. Data entries in each group have the same value in the one or more fields of the first quasi-identifier and data entries in different groups have different values in the one or more fields of the first quasi-identifier. A first group and a second group among the plurality of groups are determined according to the reference number Kr, where the first group and the second group are merged into a merging group. The number of data entries in the merging group is not less than a reference number Kr. One or more fields of at least one first quasi-identifier is masked for the merging group.

Method and system for preserving privacy of a dataset

A system and method for monitoring utilization and waste of a natural resource, such as water. Data is received indicating natural resource consumption by a facility. An indication of at least one period of natural resource usage by the facility is received. Natural resource usage corresponding to utilization of the natural resource for a useful purpose. Quantities of the natural resource consumed by the facility during the at least one period of water usage is recorded as a utilized quantity.

Water consumption monitor

A system and method for responding to a query. An original query is received. A first semantic query and a second semantic query are extracted from the information of the original query. The first semantic query is transformed, based upon semantic analysis, into a numeric model query. The second semantic query is submitted to a semantic analyzer and the numeric model query is submitted to a numeric model analyzer. A response for the second semantic query and a response for the numeric model query are integrated into an answer for the original query.

Unified numerical and semantic analytics system for decision support

A method includes parsing input from a requestor, where the input includes at least one of a query and a command that is parsed into a structured query having an indication of at least one data stream or set of data streams and at least one action to be performed on the at least one data stream or set of data streams. The method further includes mapping the structured query into a graph of processing elements that are selected and interconnected so as to execute the structured query; instantiating the graph of processing elements and connecting and initializing the instantiated graph of processing elements with an identified at least one data stream or set of data streams to receive data there from; and outputting a result of the structured query to the requestor.

System and method for querying data streams

A method, information processing system, and computer readable storage medium manage public relations queries using semantic analysis. A public relations query expressed in natural language is received from a user. A set of relevant topics and subjects associated with the query are identified. A set of information sources are identified that comprise data associated with the set of topics and subjects based on the set of topics and subjects. A set of data from the set of information sources is identified that satisfies the query. A set of weights are assigned to the set of data that has been identified. A set of data elements within the set of data that comprises a set of weights above a given threshold are identified. A response to the query is generated using the set of data elements that has been identified.
