The embodiments relate to generating hierarchical patterns based on a corpus of text. The corpus is analyzed, which includes extracting a set of features of the corpus. A set of grammatical patterns are generated based on the extracted features. The set of grammatical patterns includes at least one grammatical pattern generated from an internal pattern and at least one grammatical pattern generated from an external pattern. The grammatical patterns of the set are organized into a hierarchy and/or are ranked. The hierarchy and/or ranking are visually displayed.

Hierarchical target centric pattern generation

A computer-implemented method includes determining first passages (FP) that provide evidence for one or more first relations (OOMFR) between first entities in a knowledge graph. The method includes generating an evidence index (EI) that associates the FP with the OOMFR and the first entities, receiving a query subsequent to generating the EI, and identifying, using the EI, the FP responsive to receiving the query. The method includes determining presentation aspects of the FP based on similarity information determined for the FP, and determining that second passages of the FP are substantially similar to at least one other passage of the FP. The method includes pruning the FP to generate a pruned set of passages (PSOP) that includes one or more third passages of the second passages and that does not include any other passages of the second passages. The method includes outputting the PSOP according to the presentation aspects.

Providing relevant evidence or mentions for a query

In an example, a computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to access an application programming interface (API) endpoint, log the access of the API endpoint in an API usage log, analyze the API usage log to determine characteristics associated with the API endpoint, de-parameterize the API endpoint according to the analysis of the API usage log to generate a modified API endpoint, generate a mapping of the modified API endpoint to the API endpoint, and implement the modified API endpoint in a software application.

Application programming interface endpoint analysis and modification

Methods and apparatus, including computer program products, implementing and using techniques for evaluating indexing systems. Comparative tests are performed on two or more indexing systems. Each test uses one or more of: benchmarks, metrics, estimates of input data, desired index configuration, and performance constraints. A recommendation is automatically provided for an indexing system and an optimal configuration of the indexing system is also provided, based on an evaluation metrics from the tests.

Extensible indexing system evaluation and recommendation

The mapping system and method comprises receiving a query identifying a source entity, the source entity being of a first entity-type; generating a plurality of candidate entities from an analysis of an entity-relationship graph in response to the query based on the source entity; and computing feature values for each candidate entity of the plurality of candidate entities by passing the source entity and the plurality of candidate entities to a type-specific entity recommender particular to the first entity-type.

Providing a visual and conversational experience in support of recommendations

A method includes a computer device receiving a set of images for at least one user; the computer device receiving unique visual clue inputs from the at least one user for each image of the set of images; the computer device receiving drawing gesture inputs from the at least one user for each image of the set of images; and the computer device using the visual clue and drawing gesture inputs to create passwords to provide a locked access point for at least one device.

An approach is presented for identifying related problem tickets in an information technology (IT) environment. A pattern of actions included in interactions with a computer program is determined to be effective at proactively preventing a problem in the IT environment based on a frequency at which user(s) performed the interactions which perform text and statistical analyses of content of historical problem tickets. A script based on the pattern of actions is generated. A root cause of the problem is determined based on the text and statistical analyses. Responsive to a receipt of a new problem ticket, the script is executed to automatically perform the pattern of actions. The new problem ticket is classified as being in a group of problem tickets which are related to the problem and included in the historical problem tickets. The new problem ticket is determined to specify the problem which has the root cause.

Leveraging user-to-tool interactions to automatically analyze defects in IT services delivery

Embodiments of the invention broadly contemplate systems, methods, apparatuses and program products providing a faceted search tool enabling a user to enter a natural language query that contains representative terms the user wants to search for, and a convenient interface display in which the facets which contain the searched values are automatically resolved and presented.

Methods and arrangements for conducting corruption analysis of service designs. A service design is accepted. Corrupting factors within the service design are assessed, and a corruption susceptibility score is generated. An alternative service design is generated responsive to a corruption susceptibility score fulfilling predetermined criteria.

Automated corruption analysis of service designs

An approach is presented for identifying related problem tickets in an information technology (IT) environment. User interactions with a computer program are stored. The user interactions include inputs to the computer program to search for problem tickets issued in the IT environment that have the same characteristics. One or more user interaction patterns within the user interactions are recognized. A user interaction pattern of the one or more user interaction patterns is selected based on an evaluation of effectiveness of each of the one or more user interaction patterns. Based on the user interaction pattern, a rule is generated for determining which problem tickets in the IT environment share a common characteristic. The rule is applied to additional problem tickets issued in the IT environment to identify which of the additional problem tickets share the common characteristic.

Leveraging user-to-tool interactions to automatically analyze defects in it services delivery

Techniques, an apparatus and an article of manufacture for targeted maintenance of computing devices in a system. A method includes assessing a maintenance request to determine a class of computing devices to which the request applies, selecting a propagation mechanism applicable to the class of computing devices, generating an agent based on the propagation mechanism to carry out the maintenance request on the class of computing devices, deploying the agent on at least one computing device in the class of computing devices, and propagating the agent to additional devices in the class of computing devices.

A system and associated method for detecting a statistical variation of a process from a textual log of the process as performed by a process behavior analysis (PBA) system for monitoring the process operating in an Information Technology (IT) delivery system. The PBA system includes a PBA engine and a data storage storing exception rules used by the PBA engine. The PBA engine merges entities appearing in the textual log into one or more groups based on similarities of respective time series of the entities. Control charts are generated for merged entities and the PBA engine subsequently analyzes process behavior of the process by use of the control charts for exceptions defined in the stored exception rules. The PBA engine generates a PBA report for the process pursuant to the analysis result of the textual log with detailed information including to what type of exceptions had or had not occurred.
