Context-aware approach to detection of short irrelevant texts

摘要

Systems and methods are disclosed for determining whether a short amount of text is irrelevant. A social networking server (204) includes a comment extractor (512) configured to extract one or more comments associated with a selected article. Depending on the number of comments associated with the selected article, the social networking server (204) constructs a native context and/or a transferred context. A native context feature generator (516) is configured to determine a native context feature from the constructed native context and a transferred context feature generator (518) is configured to determine a transferred context feature from the constructed transferred context. The context features (530) may be leveraged by a comment classifier (520) to determine whether a given comment is irrelevant.
