... inadequate for Information Retrieval, Question Answering, or Text Mining, where fast analysis of large quantities of text is indispensable. This paper presents two novel methods that make the kernel-based ... compu- tational costs. Kernel-based text analysis shows an excellent performance in terms in accuracy; however, these methods are usually too slow to apply to large-scale...
