Experiments relating to TREC-7 Ad Hoc, HP and VLC tasks are described and results reported. Minor re nements of last year's Ad Hoc methods do not appear to have resulted in w...

We present a new method for information retrieval using hidden Markov models HMMs and relate our experience with this system on the TREC-7 ad hoc task. We develop a general framew...
In previous work we developed a method of learning Bayesian Network models from raw data. This method relies on the well known minimal description length (MDL) principle. The MDL ...
We study and compare two combinatorial lowness notions: strong jump-traceability and well-approximability of the jump, by strengthening the notion of jump-traceability and super-l...
: Virtual backbone-based routing is a promising approach for enhancing the routing efficiency in MANETs. To establish communication in the network, the virtual backbone nodes have ...
