  • Publication number: 20180268025
    Abstract: A computer-implemented method, cognitive intelligence server and computer program product adapt a relational database containing numeric data types. At least one numeric token in the relational database is converted to a textual form. Text is produced based on relations of tokens in the relational database. A set of word vectors is produced based on the text. A cognitive intelligence query, expressed as a structured query language (SQL) query, may be applied to the relational database using the set of word vectors. At least one numeric token in the relational database may be converted to a typed string comprising a heading for a column in the relational database for which the token appears and the numeric value. Converting at least one numeric token in the relational database may comprise clustering tokens in a column of the relational database using a clustering algorithm and replacing each token in the column by a cluster identifier.

  • Publication number: 20180267977
    Abstract: A computer-implemented method, cognitive intelligence system and computer program product adapt a relational database containing multiple data types. Non-text tokens in the relational database are converted to a textual form. Text is produced based on relations of tokens in the relational database. A set of word vectors is produced for the tokens based on the text. A cognitive intelligence query expressed as a structured query language (SQL) query may be applied to the relational database using the set of word vectors. The form of non-text tokens is one of a numeric value, an SQL type, an image, a video, a time series, latitude and longitude, or chemical structures. A single word embedding model may be applied over one or more tokens in the text. A plurality of sets of preliminary word vectors are computed by applying more than one embedding model over all tokens in the text. The preliminary word vector sets are merged to form the set of word vectors.

  • Publication number: 20170154281
    Abstract: An approach is provided in which an information handling system trains multiple classifiers using a set of training samples. The information handling system selects a leader classifier from the multiple classifiers that generates the most amount of correct decisions corresponding to the set of training samples. Next, the information handling system identifies an endorser classifier from the multiple classifiers that generates the highest proportion of correct decisions among the endorser classifier's decisions matching the leader classifier's decisions, and combines the leader classifier and the endorser classifier into a combined classifier stage. In turn, the information handling system utilizes the combined classifier stage to process inquiries and generate results.

  • Publication number: 20150248680
    Abstract: An opinion score for a customer associated with a service provider can be determined based on a first function. Parameters of the first function are determined are determined in conjunction with determining parameters of a second function that relates a first probability of a customer behavior event to the opinion score and a third function that relates a second probability of a customer action to an accumulation of the opinion score over a predetermined time interval. The parameters are determined based on one or more values representative of session performance associated with the customer, a measured value of the first probability, and a measured value of the second probability. The parameters are stored in a profile associated with the customer.

  • Patent number: 8699357
    Abstract: Improved techniques are disclosed for detecting instability events in data communications systems that support inter-administrative domain (inter-domain) routing. For example, a technique for detecting an instability event in a communications system supporting inter-administrative domain routing includes the following steps. At an inter-domain router, one or more features are extracted from one or more messages obtained from at least another router in the communications system. The one or more extracted features include a path length feature, a path edit distance feature, or a combination thereof. Then, the inter-domain router detects whether an instability event has occurred in the communications system based on the one or more extracted features such that an action can be effectuated. By way of example, the one or more messages may include one or more border gateway protocol update messages and the inter-domain router may be a border gateway protocol router.
