Assignee: ADOBE INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 14:
15. A non-transitory computer-readable medium storing executable instructions, which when executed by a processing device, cause the processing device to perform operations comprising:
determining first-level topics in a hierarchical topic model (HTM) related to a corpus of documents;
determining, based on hyperbolic word embeddings of words found in documents assigned to a first-level topic of the first-level topics, hierarchical relations between pairs of the words in the documents assigned to the first-level topic;
determining statistical relations between the words and the documents assigned to the first-level topic;
determining semantic relations between the pairs of the words in the documents assigned to the first-level topic;
defining second-level topics as subtopics of the first-level topic in the HTM, based on the hierarchical relations, the statistical relations, and the semantic relations, wherein a number of the second-level topics is equal to a number of clusters determined using the hyperbolic word embeddings; and
using the HTM to provide custom content for users based on access at a client computing device to documents in the corpus.
