摘要:
A technique includes sampling at least one performance metric of a computer-based service to form time samples of the metric(s) and detecting an occurrence of an anomaly or a performance mode change in the service. The detection includes arranging the time samples in segments based on a statistical analysis of the time samples.
摘要:
To model a computing entity, information relating to transactions associated with the computing entity is received. The received information forms a collection of information. The collection is segmented into a plurality of segments, and at least one anomalous segment is identified. A model of the computing entity is built.
摘要:
Candidate service providers for a desired service are ranked. Terms describing service requirements for a desired service are determined. Service capability documents describing the services of the candidate service providers are determined using the terms describing the service requirements. Using singular value decomposition (SVD) and a metric, similarities between the terms describing the service requirements and the service capability documents are determined. The candidate service providers are ranked based on the similarities.
摘要:
One embodiment is a method that receives a description of services desired by a service requestor and then crawls web sites to extract information on services offered by service providers. The extracted information is used to transform the description of services desired by the service requestor into an improved description of services.
摘要:
One embodiment is a method that receives a list of service providers offering services at web sites and extracts content from the web sites to identify the services offered by the service providers. The method then populates service registries with the content.

摘要:
One embodiment is a method that determines transaction latencies occurring at an application server and a database server in a multi-tier architecture. The method then analyzes the transaction latencies at the application server with Central Processing Unit (CPU) utilization during a monitoring window to determine whether a change in transaction performance at the application server results from an update to an application.
摘要:
A method comprises receiving, by learning logic, historical metrics of a computing system being monitored. The learning logic determines, from the received historical metrics, forms of sub-functions that are included in an equation, wherein each sub-function represents a dependency between two components linked in a hierarchical structure representing the computing system being monitored. State determination logic receives metric values of the computing system being monitored, and determines states that minimize the equation composed of the sub-functions over the received metric values. Finally, anomalous behavior of the computing system may be detected based on the determined states.
摘要:
Methods, systems, and computer-readable and executable instructions are provided for keyword extraction. A method for keyword extraction can include extracting a number of keywords from content inside an enterprise social network utilizing pattern recognition, constructing a semantics graph based on the number of keywords, and determining content themes within the enterprise social network based on the constructed semantics graph.
摘要:
Methods, systems, and computer-readable and executable instructions are provided for organizing content. A method for organizing content can include building a customized content corpus for a user, building a concept graph customized for the user's context based on the customized corpus, and organizing, utilizing multi-view clustering, the content within the corpus based on the concept graph.
