Abstract: Disclosed in the present invention is a method for preparing nilotinib intermediate 3-(4-methyl-1H-imidazol-1-yl)-5trifluoromethyl phenylamine (I). The method comprises the following steps: taking trifluorotoluene as an initial material, and preparing the nilotinib intermediate (I) by nitration, bromization, condensation and reduction successively Compared with the prior art, the preparation method has the following advantages: a relatively high yield, the raw materials are easily obtained, a concise process and few side reactions, and is adapted to industrial production, so the development of an economic technology of the bulk drug is pro moted.

Abstract: The present invention provides a micromolecular electron transport material based on pyridine and triazole, which is represented by the formula I, and an organic light-emitting diode using the micromolecular electron transport material. The micromolecular electron transport material of the present invention can improve the capacity of electron injection, transmitting and hole-blocking, thus can gain high ET and reduce the driving voltage of device.

Abstract: A method and system of conducting named entity recognition. One method comprises selecting one or more examples for human labelling, each example comprising a word sequence containing a named entity and its context; and retraining a model for the named entity recognition based on the labelled examples as training data.

Abstract: A water-proof watch case and a method for manufacturing the same are disclosed. First, a design of a case and a bottom lid is decided, and a mold according to the design is fabricated accordingly. Next, a hard plastic material is injected into the mold to form the case and the bottom lid. Next, a soft plastic material is injected at an outer rim of the case to form at least one button, and a soft plastic material is injected at a conjunction between the case and the bottom lid to form a water-proof gasket. Finally, the hard and soft plastic materials are heated to adhere the button and the water-proof gasket to the outer rim of the case and the conjunction between the bottom lid and the case respectively.

Abstract: A Hidden Markov Model is used in Named Entity Recognition (NER). Using the constraint relaxation principle, a pattern induction algorithm is presented in the training process to induce effective patterns. The induced patterns are then used in the recognition process by a back-off modelling algorithm to resolve the data sparseness problem. Various features are structured hierarchically to facilitate the constraint relaxation process. In this way, the data sparseness problem in named entity recognition can be resolved effectively and a named entity recognition system with better performance and better portability can be achieved.
