Emergent knowledge does not come from a particular document or a particular knowledge source, but comes from a collection of documents or knowledge sources. This paper proposes a system which combines the social web contents and the semantic web technology to process the emergent knowledge from the blogosphere. The proposed system regards blog postings as(More)
In this paper, we propose and adaptive M-ary Quadrature Amplitude modulation (M-QAM) transmission scheme that jointly uses selection combining and power loading over multiple independent and identically-distributed (i.i.d) Rayleigh fading channels in multi-channel systems. We derive exact closed-form expressions of the performance of the proposed scheme in(More)
In this paper, we propose a hybrid adaptive modulation and power loading (AMPL) for wireless multi-channel system. While the hybrid adaptive modulation and diversity combining (AMDC) introduced in [1] exploits adaptive modulation and diversity combining scheme to achieve higher spectral efficiency, the proposed scheme in this paper jointly determines the(More)
In this paper, we propose a hybrid M-ary Quadrature Amplitude Modulation (M-QAM) transmission scheme that jointly uses adaptive modulation and selection combining for singular value decomposition (SVD)-based multiple-input multiple-output (MIMO) systems (AMSC-MIMO). We derive exact closed-form expressions of the performance of the proposed scheme in terms(More)
