Abstract:

With the explosive growth of internet data and the increasing user demand, the traditional search methods has been difficult to meet user's needs in the mobile search field. In order to achieve the intelligent search based on semantic understanding, it is urgent to improve the level of search from word-based to semantic-based. Facing to the open internet data resources, an intelligent search pattern on “dynamic knowledge network + calculation operator”was proposed. Then, dynamic knowledge network was described in detail, which included theoretical basis, structure model, system model and features. Furthermore, it was presented about the basic structure of intelligent search based on dynamic knowledge network, which provided the support about theory and model for intelligent search. Finally, the main problems and challenges in the future were explained.

Key words: intelligent search, knowledge network, hyper-graph, semantic understanding
