This article proposes a new general, highly efficient algorithm for extracting domain terminologies. This domain-independent algorithm with multi-layers of filters is a hybrid of statistic-oriented and rule-oriented methods. Utilizing the features of domain terminologies and the characteristics that are unique to Chinese, this algorithm extracts domain terminologies by generating multi-word unit （MWU） candidates at first and then fihering the candidates through multi-strategies. Our test resuhs show that this algorithm is feasible and effective.

This paper considers the worst–case estimation problem in the presence of unknown but bounded *** to stochastic approaches, the goal here is to confine the estimation error within a bounded set. Previous work dealing with the problem has shown that the complexity of estimators based upon the idea of constructing the state consistency set(e.g. the set of all states consistent with the a-priori information and experimental data) cannot be bounded a-priori, and can, in principle, continuously increase with time. To avoid this difficulty in this paper we propose a class of bounded complexity filters, based upon the idea of confining r–length error sequences(rather than states) to hyperrectangles. The main result of the paper shows that this can be accomplished by using Linear Time Invariant(LTI) filters of order no larger than r. Further, synthesizing these filters reduces to a combination of convex optimization and line search.
