  • Patent number: 10896458
    Abstract: Disclosed herein are technologies for providing recommendations as to particular products and/or services that are customer specific and general, based on customer preference and inquiry. The recommendations are provided as part of an online shopping system. In accordance with one aspect, an item query is received from a customer, and analyzed by a query analyzer to determine if the query is a general item query or a specific item query. A search may be performed for items based on the item query in an items database listing items offered for purchase. If the query is the general item query, customer preference is determined from results of the search. If the query is the specific item query, the items from the results of the search are grouped based on cost performance. The items of the search result are ranked and provided to the customer.

  • Patent number: 10637964
    Abstract: The present disclosure involves systems, software, and computer implemented methods for mutual reinforcement of edge devices with dynamic triggering conditions and/or computation frequencies. In one example, a first edge device in multiple edge devices in an Internet of Things (IoT) system monitors at least a first parameter. The first edge device determines whether a first condition from one set of conditions is satisfied based on at least the monitored first parameter. In response to determining that the first condition is satisfied, the first edge device automatically transmits a signal to a second edge device in the multiple edge devices to initiate or stop monitoring of a second parameter by the second edge device.

  • Publication number: 20200097907
    Abstract: In one embodiment, a method receives requests where each request includes an origin, a destination, a time dependency, a request, and a cost of the request. Lines are generated from the requests with each line including a duration from the time dependency, the origin, the destination, and a profit based on the cost. Paths are generated that include a set of lines with each path including an identification of the lines in the path, a set of requests in the path, and a weight based on the profit of the set of requests in the path. The paths are analyzed to select a number of paths from the paths based on the weight of each path. A schedule to fulfill the requests is then output. A combination of requests is assigned to a single entity based on a set of requests in a path selected for the single entity.

  • Publication number: 20190303815
    Abstract: Various embodiments of systems and methods for distributed manufacturing are described herein. The method includes identifying a time window for executing an order for a product comprising various components. A task allocator is executed to read data related to the product to generate manufacturing topology of the product representing components with nodes and their manufacturing inter-dependency with edges. Based upon the manufacturing topology, supplier's timeline topology of the product is generated to indicate time taken to manufacture the product by respective suppliers. The generated suppliers' timeline topologies are merged with time inter-dependency relationship between each node to generate production timeline topology of the product. Routes from nodes without predecessor nodes to nodes without successor nodes in the production timeline topology is generated. An optimal route having minimum manufacturing cost of the product is selected.

  • Patent number: 10360521
    Abstract: A recommendation system for generating location recommendations for drivers of public service vehicles is disclosed. The system segments a map of an area of interest into segments or regions and analyzes historical call data to estimate demand in the regions. The analysis also determines values of the calls in the regions. For example, the analysis estimates the probability of the calls and values of such calls in each region. The analysis may include time patterns to improve accuracy of the estimation. By using the results of the analysis along with current information, such as current location of a vehicle, current time, and real-time traffic information, a holding location recommendation is generated.

  • Patent number: 10296837
    Abstract: A system and method for analyzing documents, such as posts, on-line reviews and comments from people based on topics of the documents, to determine general sentiment of users is disclosed. Topics from the documents and their corresponding sentiment polarities are extracted. The documents are regarded to be constituted by a series of topics. The sentiment for a topic is represented by a quadruple (k, so, h, i), where k is the topic, so is the sentiment opinion, h is the comment or post holder, and i is the document. A quintuple (k, sup, p, n, ne) is used to illustrate the topics and corresponding sentiments and is stored in S, where sup indicates the frequency of the topic, and p (positive), n (negative) and ne (neutral) are different types of opinions of the users. From the quintuple set S, every topic is related to three kinds of sentiment opinions (positive, negative, and neutral), enabling determination of popular topics in documents as well as the users' sentiment polarities.

  • Publication number: 20180357604
    Abstract: Systems and methods are provided for tracking parts to be used in a production line. First and second digital outputs that represent, respectively, a first physical property of a first part and a second physical property of a second part, are received by one or more data processors. The first part has a first expected delivery date, and the second part has a second expected delivery date. The first and second physical properties are independently selected from the group consisting of humidity, temperature, and shock. The first digital output is compared to a first predetermined value representing damage to the first part. After a determination that first part is damaged and will not be available on the first expected delivery date, an alert is generated. The one or more data processors output the alert to at least one of a display screen and a computer-readable medium.
