Medical information extraction system and method based on depth learning and distributed semantic features
ActiveCN105894088AAvoid floating point overflow problemsHigh precisionNeural learning methodsNerve networkStudy methods
he invention discloses a medical information extraction system and method based on depth learning and distributed semantic features. The system is composed of a pretreatment module, a linguistic-model-based word vector training module, a massive medical knowledge base reinforced learning module, and a depth-artificial-neural-network-based medical term entity identification module. With a depth learning method, generation of the probability of a linguistic model is used as an optimization objective; and a primary word vector is trained by using medical text big data; on the basis of the massive medical knowledge base, a second depth artificial neural network is trained, and the massive knowledge base is combined to the feature leaning process of depth learning based on depth reinforced learning, so that distributed semantic features for the medical field are obtained; and then Chinese medical term entity identification is carried out by using the depth learning method based on the optimized statement-level maximum likelihood probability. Therefore, the word vector is generated by using lots of unmarked linguistic data, so that the tedious feature selection and optimization adjustment process during medical natural language process can be avoided.

Provided herein are methods that enable parallel evaluation of multiple functional nucleic acids in individual cells or subpopulations of cells, in the context of incubation with other types of single cells. The key insight is concurrent measurement of polynucleic acids derived from small populations of at least two different cell types, such that function in one cell type is linked to the clonal identity of another cell. These methods simultaneously process thousands, millions, or more single cells or small populations of cells. The method integrates molecular, algorithmic, and engineering approaches. This invention has broad and useful application in a number of biological and medical fields, including immunology and drug discovery.
