Patent number: 11276076Abstract: A method and a system for generating a digital content recommendation. The method comprises receiving a request for the digital content recommendation. Based on the request, a first content item and a second content item responsive to the request are selected, and a relevancy parameter and a completion parameter for each of the first content item and the second content item are determined. Based on the relevancy parameter and the completion parameter, the first content item and the second content item are ranked, and a digital content recommendation is generated based on the ranking of the first content item and the second content item.Type: GrantFiled: April 1, 2019Date of Patent: March 15, 2022Assignee: YANDEX EUROPE AGInventors: Yevgeny Andreevich Sokolov, Viktor Grigorievich Lamburt, Boris Dmitrievich Sharchilev, Nikita Leonidovich Senderovich

Patent number: 10674215Abstract: A method of determining a relevancy parameter for a digital content item and a system for implementing the method. The digital content item is originated from a content channel associated with a recommendation system. The method is executable by the server. The method comprises: identifying a pool of users associated with the content channel, a given user of the pool of users being associated with the content channel. The method comprises using the pool of users to explore and predict a relevancy parameter. The relevancy parameter is then used for predicting relevancy parameter of the digital content item for a user outside of the pool of users based on the user interactions of the first user.Type: GrantFiled: March 29, 2019Date of Patent: June 2, 2020Assignee: YANDEX EUROPE AGInventors: Yevgeny Andreevich Sokolov, Victor Grigorievich Lamburt, Boris Dmitrievich Sharchilev, Andrey Petrovich Danilchenko

Publication number: 20190163758Abstract: A method and server for presenting an item with potentially undesirable content to a user are disclosed. The method comprises: receiving a presentation request and user interactions; and generating a first list of items. Items are associated with respective features and web resources. Items are ranked in first list based on user-specific scores indicative of their estimated relevance to user. A given item is associated with a given rank in first list. The method also comprises: generating for items demoting scores indicative of a degree of undesirability of content originating from respective resources; generating for items adjusted scores based on user-specific and demoting scores; generating a second list where items are ranked according to adjusted scores, where the given item is associated with an adjusted rank in the second list; and triggering presentation of items from second list to user. The given item is presented at the adjusted rank.Type: ApplicationFiled: June 15, 2018Publication date: May 30, 2019Inventors: Dmitry Sergeevich ZHIVOTVOREV, Victor Grigorievich LAMBURT, Vladimir Vladimirovich NIKOLAEV, Dmitry Valerievich USHANOV, Yevgeny Andreevich SOKOLOV
