Abstract

A method, system and computer readable medium for generating a cognitive insight comprising: receiving information regarding a temporal sequence of events; performing a temporal topic machine learning operation on the temporal sequence of events; generating a cognitive profile based upon the information generated by performing the temporal topic machine learning operation; and, generating a cognitive insight based upon the cognitive profile generated using the temporal topic machine learning operation.

First claim

What is claimed is:

1. A computer-implementable method for generating a cognitive insight comprising:
receiving data from a plurality of data sources, at least one of the plurality of data sources providing information regarding a temporal sequence of events;
performing a cognitive learning operation via a cognitive inference and learning system, the cognitive learning operation processing data from at least some of the plurality of data sources, the cognitive learning operation comprising a plurality of cognitive learning operation lifecycle phases, the cognitive learning operation lifecycle phases interacting with one another by providing and receiving data between adjacent phases, the cognitive inference and learning system comprising a cognitive platform, the cognitive learning operation applying a cognitive learning technique to generate a cognitive learning result;
performing a temporal topic machine learning operation on the temporal sequence of events;
generating a cognitive profile based upon the cognitive learning result and information generated by performing the temporal topic machine learning operation, the cognitive profile comprising an instance of a cognitive persona and referencing personal data associated with a user, the cognitive persona comprising an archetype user model representing a common set of attributes associated with a hypothesized group of users; and,
generating a cognitive insight based upon the cognitive profile generated based upon the cognitive learning result and the information generated by performing the temporal topic machine learning operation; and wherein
the plurality of cognitive learning techniques comprising a direct correlations cognitive learning technique, an explicit likes/dislikes cognitive learning technique, a patterns and concepts cognitive learning technique, a behavior cognitive learning technique, a concept entailment cognitive learning technique, and a contextual recommendation cognitive learning technique, the direct correlations cognitive learning technique being associated with a declared learning style and bounded by a data-based cognitive learning category, an explicit likes/dislikes cognitive learning technique being associated with the declared learning style and bounded by an interaction-based cognitive learning category, the patterns and concepts cognitive learning technique being associated with an observed learning style and bounded by the data-based cognitive learning category, the behavior cognitive learning technique being associated with the observed learning style and bounded by the interaction-based cognitive learning category, the concept entailment cognitive learning technique being associated with an inferred learning style and bounded by the data-based cognitive learning category, and a contextual recommendation cognitive learning technique being associated with the inferred learning style and bounded by the interaction-based cognitive learning category.

2. The method of claim 1 , wherein:
the temporal topic machine learning operation discovers a plurality of event topics contained within a corpus contained within the temporal sequence of events.

3. The method of claim 2 , wherein:
the temporal topic machine learning operation generates a temporal topic model using the plurality of event topics, the temporal topic model comprising a topic model having a temporal aspect, the topic model comprising a statistical model implemented to discover abstract event topics occurring within the corpus, the temporal topic model comprising clusters of event topics, the event topics comprising portions of corpora associated with a particular temporal event and data attributes associated with the particular temporal event, a cluster of event topics having an associated individual node in an augmented gamma belief network.

4. The method of claim 3 , further comprising:
iteratively processing the corpus over time to identify information regarding relative preeminence of event topics associated with various events; and,
using the information regarding relative preeminence of event topics to populate the temporal topic model.

5. The method of claim 4 , wherein:
the temporal topic model comprises a plurality of events, an earlier event of the plurality of events being separated from a next later event by a time interval, each of the plurality of events comprising a respective plurality of event topics.

6. The method of claim 5 , wherein:
each of the plurality of event topics comprise a plurality of associated attributes; and,
at least some of the associated attributes are used when determining the relative preeminence of event topics over time.

7. A system comprising:
a processor;
a data bus coupled to the processor; and
a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for:
receiving data from a plurality of data sources, at least one of the plurality of data sources providing information regarding a temporal sequence of events;
performing a cognitive learning operation via a cognitive inference and learning system, the cognitive learning operation processing data from at least some of the plurality of data sources, the cognitive learning operation comprising a plurality of cognitive learning operation lifecycle phases, the cognitive learning operation lifecycle phases interacting with one another by providing and receiving data between adjacent phases, the cognitive inference and learning system comprising a cognitive platform, the cognitive learning operation applying a cognitive learning technique to generate a cognitive learning result;
performing a temporal topic machine learning operation on the temporal sequence of events;
generating a cognitive profile based upon the cognitive learning result and information generated by performing the temporal topic machine learning operation, the cognitive profile comprising an instance of a cognitive persona and referencing personal data associated with a user, the cognitive persona comprising an archetype user model representing a common set of attributes associated with a hypothesized group of users; and,
generating a cognitive insight based upon the cognitive profile generated based upon the cognitive learning result and the information generated by performing the temporal topic machine learning operation; and wherein
the plurality of cognitive learning techniques comprising a direct correlations cognitive learning technique, an explicit likes/dislikes cognitive learning technique, a patterns and concepts cognitive learning technique, a behavior cognitive learning technique, a concept entailment cognitive learning technique, and a contextual recommendation cognitive learning technique, the direct correlations cognitive learning technique being associated with a declared learning style and bounded by a data-based cognitive learning category, an explicit likes/dislikes cognitive learning technique being associated with the declared learning style and bounded by an interaction-based cognitive learning category, the patterns and concepts cognitive learning technique being associated with an observed learning style and bounded by the data-based cognitive learning category, the behavior cognitive learning technique being associated with the observed learning style and bounded by the interaction-based cognitive learning category, the concept entailment cognitive learning technique being associated with an inferred learning style and bounded by the data-based cognitive learning category, and a contextual rec
