Examples are disclosed that relate to recommending resources accessible via an online ecosystem. One example provides a computing system including a logic machine and a storage machine holding instructions executable by the logic machine to, for each of a plurality of users of an online ecosystem, obtain and store interaction data regarding interactions of the user with one or more digital content items accessible via the online ecosystem, and receive a request associated with a selected user for a recommendation related to resources accessible via the online ecosystem. The instructions may be further executable to retrieve, for at least a subset of users of the plurality of users, the interaction data, apply a weighted matching algorithm to determine one or more similar users that are similar to the selected user, and output a recommendation for the selected user of one or more recommended resources accessible via the online ecosystem.
Please help me write a proper abstract based on the patent claims. CLAIM: 1.

The computing system of claim 1, wherein the one or more recommended resources comprises one or more recommended other users of the one or more similar users with whom to participate in an online interactive activity. 3. The computing system of claim 1, wherein the one or more recommended resources comprises one or more digital content items recommended for consumption. 4. The computing system of claim 1, wherein the interaction data comprises, for each of the plurality of users, a plurality of attributes regarding the user, and wherein the instructions are executable to apply respective weights to at least a subset of the plurality of attributes to form a weighted subset of attributes; and compare the weighted subset of attributes to a same subset of attributes associated with the selected user. 5. The computing system of claim 4, wherein the respective weights are selected based at least in part on a user input associated with the selected user. 6. The computing system of claim 4, wherein the instructions are further executable to receive a user input associated with the selected user requesting to access a selected resource of the one or more recommended resources, and in response adjust the respective weights. 7. The computing system of claim 1, wherein the instructions are further executable to update the interaction data. 8. The computing system of claim 1, wherein the subset of the plurality of users belongs to a cluster of the plurality of users that share an attribute with the selected user. 9. The computing system of claim 1, wherein the one or more digital content items comprise a multimedia content item and/or an application. 10. The computing system of claim 1, wherein the instructions executable to obtain the interaction data are executable to obtain user-specific non-gaming data for each of the plurality of users. 11. A computing system, comprising: a logic machine; and a storage machine holding instructions executable by the logic machine to, for each of a plurality of users of an online gaming service, obtain and store interaction data regarding interactions of the user with one or more digital content items accessible via the online gaming service; receive a request associated with a selected user for a recommendation related to resources accessible via the online gaming service; in response to receiving the request, retrieve, for at least a subset of users of the plurality of users, the interaction data; apply a weighted matching algorithm to determine one or more similar users of the subset of users that are similar to the selected user; and based at least in part on determining the one or more similar users via the weighted matching algorithm, output a recommendation for the selected user of one or more recommended resources accessible via the online gaming service. 12. The computing system of claim 11, wherein the request associated with the selected user is a request for matchmaking with one or more recommended other users of the one or more similar users, and wherein the one or more recommended resources comprises the one or more recommended other users with whom to participate in an online game. 13. The computing system of claim 11, wherein the one or more recommended resources comprises one or more games. 14. The computing system of claim 11, wherein the interaction data comprises, for each of the plurality of users, a plurality of attributes regarding the user, and wherein the instructions are executable to apply respective weights to at least a subset of attributes of the interaction data retrieved to form a weighted subset of attributes; and compare the weighted subset of attributes to a same subset of attributes associated with the selected user. 15. The computing system of claim 14, wherein the instructions are further executable to receive a user input associated with the selected user requesting to associate with one or more recommended other users of the one or more similar users, and in response adjust the respective weights. 16. The computing system of claim 11, wherein the instructions are further executable to update the interaction data. 17. The computing system of claim 11, wherein the subset of the plurality of users belongs to a cluster of the plurality of users that share an attribute with the selected user. 18. The computing system of claim 11, wherein the instructions executable to obtain the interaction data are executable to obtain user-specific non-gaming data for each of the plurality of users. 19. On a computing system, a method, comprising: for each of a plurality of users of an online ecosystem, obtaining and storing interaction data regarding interactions of the user with one or more digital content items accessible via the online ecosystem; receiving a request associated with a selected user for a recommendation related to resources accessible via the online ecosystem; in response to receiving the request, retrieving, for at least a subset of users of the plurality of users, the interaction data; applying a weighted matching algorithm to determine one or more similar users of the subset of users that are similar to the selected user; based at least in part on determining the one or more similar users via the weighted matching algorithm, outputting a recommendation for the selected user of one or more recommended resources accessible via the online ecosystem; and receive a user input associated with the selected user, the user input indicating an inclination of the selected user regarding the recommendation, and in response adjust one or more weights used to apply the weighted matching algorithm. 20. The method of claim 19, wherein the interaction data comprises, for each of the plurality of users, a plurality of attributes regarding the user, and wherein the instructions are executable to apply respective weights to at least a subset of the plurality of attributes to form a weighted subset of attributes; and compare the weighted subset of attributes to a same subset of attributes associated with the selected user.
