Self-adaptive Chinese word segmentation method based on embedded representation

The embodiment of the invention discloses a self-adaptive Chinese word segmentation method based on embedded representation and belongs to the field of information processing. The method is characterized in that an embedded representation layer of a character is shared by a word segmentation network and a character language model. As for embedded representation of the character, on the one hand, hidden multi-granularity local features of a to-be-segmented text is obtained by means of the word segmentation network based on convolutional neural network; then label probability of the character is obtained through a forward network layer; finally, label inference is used to obtain the optimum segmentation result in the sentence level; on the other hand, an unlabelled text is randomly extracted, a character next to the character is predicted by means of a character language model based on a long- and short-term memory unit (LSTM) recurrent neural network and the word segmentation network is constrained. By modeling a character co-representing relationship in texts in different fields by means of the character language model and transferring information to the word segmentation network by means of embedded representation, the field transfer ability of word segmentation is enhanced, and the method has very huge practical value.

Method for remediating chromium polluted soil by enabling super fine iron powder to cooperate with microorganisms

The invention belongs to the technical field of ecological remediation, and discloses a method for remediating chromium polluted soil by enabling super fine iron powder to cooperate with microorganisms. The method comprises the following step of: sufficiently mixing the super fine iron powder and mixed bacteria with the chromium polluted soil to culture, thereby completing remediation of chromiumpolluted soil, wherein the mixed bacteria comprise chromium reducing bacteria, iron reducing bacteria and sulphate reducing bacteria. According to the method disclosed by the invention, the characteristic of corroding and releasing H2, in a remediation process, of the super fine iron powder is sufficiently utilized, and the microorganisms which take H2 as an electron donor are induced to grow andbreed on the surface, so that the microorganisms obtain energy, high-valence-state high-toxicity hexavalent chromium is reduced to be low-valence-state low-toxicity trivalent chromium, and the low-valence-state low-toxicity trivalent chromium is converted into occurrence forms, which are difficult in bioavailability, such as an iron-manganese combined form, an organic combined form and a residualform from a water-soluble form, an exchangeable form and a carbonate combined form, and therefore, transfer ability and bioavailability, in the soil, of chromium are reduced.
