A framework for product named entity recognition in Chinese was presented using Conditional Random Fields with multiple features in this paper. It differentiates from most of the previous approaches mainly as follows. Firstly, introducing the domain ontology features to the CRFs model can use its semantic information. Secondly, combining internal and(More)
High complexity of Dijkstra Algorithm limits its application in searching the shortest path in road network. Thus it is necessary to improve the efficiency of searching the shortest path in road network. Combining the existing conventional algorithms for restricted searching area, a shortest path algorithm based on cut-corner orientation rectangle is(More)
