摘要:
A composite language model may include a composite word predictor. The composite word predictor may include a first language model and a second language model that are combined according to a directed Markov random field. The composite word predictor can predict a next word based upon a first set of contexts and a second set of contexts. The first language model may include a first word predictor that is dependent upon the first set of contexts. The second language model may include a second word predictor that is dependent upon the second set of contexts. Composite model parameters can be determined by multiple iterations of a convergent N-best list approximate Expectation-Maximization algorithm and a follow-up Expectation-Maximization algorithm applied in sequence, wherein the convergent N-best list approximate Expectation-Maximization algorithm and the follow-up Expectation-Maximization algorithm extracts the first set of contexts and the second set of contexts from a training corpus.

A guiding mechanism for an electric tool includes at least two guiding elements at least one of which has a first end portion having at least one protruding portion extending outwards therefrom and the other of which has a second end portion having at least one groove therein which may be engaged with the protruding portion. The groove has a cut-out and the protruding portion has an elastic clamping portion which may be engaged with the cut-out.

A power unit includes two or more power modules (1, 2, 3), each comprising an engine (11), a transfer case (12) connected to the engine (11) and a hydraulic pump set (13) connected to the transfer case (12). A controlling method for the power unit is also disclosed. Compared to the prior art of using a single super high power engine, the hydraulic mobile crane using the in power unit has advantages of low cost, high reliability, and not being subjected to the restrictions by road transportation conditions during transportation.

A hydraulic control system and a hydraulic control method are disclosed. The hydraulic control system comprises a first closed pump (P1) and a first engine (M1) connected with each other, a second closed pump (P2) and a second engine (M2) connected with each other, and a hydraulic motor (P3). The first closed pump (P1), the second closed pump (P2) and the hydraulic motor (P3) are connected in parallel. Compared with the prior art, the present hydraulic control system has advantages of wider engine model selection range, higher reliability and better micro-motion performance.
