Abstract: An aspect of this invention is a method that includes monitoring sensors to collect information for a transportation route, and generating a graph from the collected information where the graph includes a plurality of nodes, each node representing a stop on the at least one transportation route. Each of respective nodes is associated with a corresponding transportation stop density and a corresponding passenger leaving rate. The corresponding transportation stop density is compared with at least one predetermined density threshold and the corresponding passenger leaving rate is compared with at least one predetermined leaving rate threshold to determine a level of dissatisfaction for each of the respective nodes. A tangible output is generated that identifies a level of user dissatisfaction for each of the plurality of nodes.

Abstract: At least one computer processor obtains access to a relationship network and a network of a different kind than the relationship network. The at least one computer processor also obtains a user query and carries out a multiple heterogeneous networks search on the relationship network and the network of the different kind than the relationship network, by executing on the at least one computer processor a multiple heterogeneous network search module, to obtain a ranked output list responsive to the user query.

Abstract: A method of ranking workers for an incoming task includes recording a list of completed tasks in a computer data structure, extracting first attributes from the list for the tasks that were completed during a pre-determined period, generating a first feature vector for each task and worker from the first extracted attributes, training a Support Vector Machine (SVM) based on the feature vector to output a weight vector, extracting second attributes from an incoming task, generating a second feature vector for each worker based on the second extracted attributes, and ranking the workers using the second feature vectors and the weight vector. The first attributes may be updated during a subsequent period to re-train the SVM on updated first feature vectors to generate an updated weight vector. The workers may be re-ranked based on the second feature vectors and the updated weight vector. Accordingly, the feature vectors are dynamic.

Abstract: A method of simulating an online social network (OSN) includes modeling behavior data of a user, the behavior data including sampled real data, and simulating a behavior of the OSN using the modeled data.

Abstract: A weather forecast system, method of forecasting weather and a computer program product therefor. A forecasting computer applies a grid to a forecast area and provides a weather forecast for each grid cell. Population movement sensors sense population movement in the area. A swarm detector detects patterns in area population movement that indicate swarm activity, from which the swarm detector predicts swarm patterns. A planning module receives area weather forecasts and swarm patterns, and provides swarm path indications to the forecasting system for adjusting the grid applied to the forecast area.

Abstract: One embodiment of a method for detecting a lost sale due to an out-of-shelf condition in a retail environment includes automatically detecting when a customer fails to purchase an expected product, based at least in part on an observation of a current behavior of the customer in the retail environment and on a purchasing history of the customer, and inferring, based on the automatically detecting, that the expected product is out-of-shelf.

Abstract: One embodiment of a system for detecting a lost sale due to an out-of-shelf condition in a retail environment includes a plurality of sensors distributed throughout the retail environment for monitoring a current behavior of a customer in the retail environment, a database for storing a purchasing history of the customer, and a matching system for automatically detecting when the customer fails to purchase an expected product, based at least in part on the current behavior and on the purchasing history, and for inferring, based on the automatically detecting, that the expected product is out-of-shelf.

Abstract: A system for evaluating a satisfaction of a customer in a retail environment includes a search system for identifying an item for which the customer is searching in the retail environment, a plurality of sensors for monitoring an activity of the customer with respect to the item in the retail environment, and an evaluation system for automatically evaluating the satisfaction of the customer based on the activity of the customer with respect to the item.

Abstract: A method includes receiving a request from a requestor to validate a data assemblage expressed in Javascript Object Notation (JSON); translating the data assemblage expressed in JSON into an extensible markup language (XML) instance; validating the XML instance using syntactic schema and semantic schema specifications; and sending a response to the requestor. For a case where the data assemblage contains invalid data in at least one field the response includes an output array containing information for specifying valid data for the at least one field and a message explaining a reason why the field is invalid. A system for performing the method is also described, as is a computer program product that can be used to execute the method.

Abstract: A travel routing system, method and program product therefor. A location detector detects a current location. A geographical database provides details of a given area. Selecting a destination causes a route generator to generate routes through the area from the current location. A flood simulator receives meteorological data and determines flooding along the routes. A risk-modeling unit determines the risk to travelers of using each route. Before the risk-modeling unit is deployed, it is trained off-line to model travel risks using incidents in an incident data store and simulated flooding in the vicinity of the incidents.

Abstract: An aspect of this invention is a method that includes receiving input data from an application. The input data includes information descriptive of at least one field. The method further includes processing the input data to form an array composed of legal data for the at least one field. The array is formed by merging a result of processing syntactic constraints and a result of processing semantic constraints. The method further includes outputting the array to the application. A system for performing the method is also described, as is a computer program product that can be used to execute the method.
