  • Patent number: 11481572
    Abstract: The present disclosure provides a method and apparatus for evaluating article value based on artificial intelligence, and a storage medium. The solution of present disclosure may be employed to pre-mine high-quality articles and low-quality articles as training data, and train according to the training data to obtain a value-scoring model. As such, value evaluation needs to be performed for the to-be-evaluated article, it is feasible to first perform feature extraction for the to-be-evaluated article, determine a score of the to-be-evaluated article based on the extracted features and the value-scoring model, and thereby implement effective evaluation of the article value.

  • Patent number: 11429680
    Abstract: Embodiments of the present disclosure disclose a method and apparatus for subscribing to a topic. The method includes: matching a persistent topic for a retrieval keyword based on the retrieval keyword of a user combined with at least one of historical behavior or a subscription record of the user; returning the persistent topic to a client for display, so that the user performs subscription; and saving the persistent topic subscribed to by the user, and when a matching resource corresponding to the persistent topic subscribed to by the user is updated, recommending the updated matching resource to the user. Since a recommendation strategy can be timely adjusted according to real-time behavior of a user combined with historical behavior, the probability of hitting a topic of interest to the user is increased.

  • Patent number: 10769133
    Abstract: The present disclosure provides a method and apparatus for recognizing a low-quality news resource, a computer device and a readable medium. The method comprises: obtaining information of a to-be-recognized news resource; determining whether the to-be-recognized new resource is a low-quality news resource, according to a pre-built low-quality news information repository and the information of the to-be-recognized news resource. The technical solutions of the present disclosure may be employed to automatically recognize whether the to-be-recognized news resource is the low-quality resource through the information of the to-be-recognized news resource such as the text information and/or pictures, and can overcome technical problems in the prior art such as time-consuming and arduous manual-check manner and a low recognition efficiency due to leakage in checking.

  • Patent number: 10453448
    Abstract: Embodiments of the present disclosure provide a method and a device for managing a dialogue based on artificial intelligence. The method includes the followings. An optimum system action is determined from at least one candidate system action according to a current dialogue status feature, a candidate system action feature and surrounding feedback information of the at least one candidate system action and based on a decision model. Since the current dialogue status corresponding to the current dialogue status feature includes uncertain results of natural language understanding, the at least one candidate system action acquired according to the current dialogue status also includes the uncertain results of natural language understanding.

  • Publication number: 20140180461
    Abstract: A request to calculate workload for a number of time buckets is received. In response to the request, one or more sets of activities with equal execution timeframe are determined. In one aspect, for the one or more sets of activities, net execution duration of activities from the one or more sets of activities is aggregated to determine workloads of the one or more sets of activities. Planned work time consumption of the determined workloads is calculated. In one aspect, calculated planned work time consumption of the workloads is distributed across the number of time buckets. Distributed planned work time consumption of the workloads is aggregated, by the time buckets to calculate the workload for the time buckets.

  • Patent number: 5978539
    Abstract: An optical interconnection device has a passive control mechanism for substantially eliminating thermal effects on optical properties of the apparatus Specifically, the interconnection apparatus includes a control material coupled to an optical circuit substrate, wherein the control material has a thermal expansion coefficient that is different than a substrate thermal expansion coefficient. In response to an increase or decrease an ambient temperature, the control material thermally expands or contracts at a different rate than the substrate to create a non-planar substrate distortion transmitted to the core portion, thereby creating a temperature independent optical path length within the optical core portion.
