Abstract: A personalized selection of applications for presentation on a web-based interface can be produced. A first vector can represent one or more first words from a first query. A second query, including the one or more first words and one or more second words, can be transmitted in response to a first determination that a measure of similarity between the first vector and a second vector, which represents the one or more second words, is greater than a threshold. The second vector can be obtained from a knowledge base. A response to the second query can include an identification of a first application. A cluster of applications, including the first application and a second application, can be generated in response to a second determination of an existence of a relationship between the first application and the second application. The personalized selection of applications can be produced based on the cluster.
