Associated search method and system of chemical knowledge

Abstract

The invention provides an associated search method and system of chemical knowledge. The method takes a chemical resource bundle file (8) as the base and comprises the following steps: receiving the keywords to be searched which are input by a user; searching the keywords and obtaining an index address of a chemical substance matched with the keywords; obtaining the chemical substance content according to the index address of the chemical substance and displaying the chemical substance content such as the name of the chemical substance on a result list; taking the chemical substance on the result list as a center knowledge object; obtaining reactants associated with the chemical substance, resultants associated with the chemical substance or other reactants capable of reacting with the chemical substance, and then taking the reactants, the resultants or the other reactants as divergent knowledge objects; constructing a dynamic relation network chart composed of the center knowledge object and the divergent knowledge objects and displaying the knowledge content relative to the objects in the dynamic relation network chart. According to the associated search method and system of the chemical knowledge, the semantic associated search is supported, and the chemical substances and associated knowledge points which the user wants to learn can also be searched so that the study efficiency can be obviously improved.

Description

technical field

[0001] The invention relates to a search engine and a search method, in particular to a chemical knowledge correlation search method and system. The chemical knowledge correlation search system of the present invention can be applied to electronic learning equipment, such as learning machines, electronic dictionaries, early education machines, learning pen etc. Background technique

[0002] E-learning equipment is often used for the study of chemical knowledge, such as the inquiry and study of chemical substances. Traditional handheld electronic learning devices generally store chemical resource package files, chemical laboratory modules and chemical search engine modules. There are three main ways to learn chemical knowledge. The first is a catalog-based text browsing learning method, the second is a One is the virtual chemistry laboratory learning method, and the third is the keyword search learning method.

[0003] Catalog-style text browsing learning me...
