The method comprises the steps of setting reserved words for computing elements and conditional elements according to designs of the computing elements and the conditional elements in a computer language, carrying out logic expression by matching the computing elements and the conditional elements, and judging sentences and computing sentences in expression forms. For example, "if the time to report is within the waiting period, we pay for 20% of the amount of the basic insurance of the contract" as follows:
IF [ report time < waiting period ] (payoff=20% of the basic insurance amount)
The time "IF [ ] ()" is a judgment statement, "payoff amount=20% of the basic insurance amount" and "report time > waiting period" are calculation statements, wherein the calculation statement contains variable elements, calculation elements and numerical value elements, one calculation element must be linked with two elements which are variables or numerical values, and the judgment statement is linked with a plurality of calculation statements.

And a third step of: extracting the logic expression, namely extracting the logic expression by utilizing dependency syntactic analysis and rules: for sentences containing logic expressions, setting the sentences as sentences to be extracted for the existence of condition elements, and dividing the sentences to be extracted into two calculation sentences of which the case reporting time is in a waiting period and which pay for claims according to 20% of the basic insurance amount of the contract according to syntactic analysis; carrying out logic expression extraction on a statement to be extracted according to a syntax extraction rule constructed by constructing a dependency phrase structure tree and constructing a trigger word, taking a case report time in a waiting period as an example, wherein the dependency tree is shown in fig. 4, is mapped into an in or a < accordingto a calculation element in …, is judged to be <', and finds a subject case report time and a fixed language waiting period according to the dependency relationship in the dependency tree to construct a logic expression case report time < waiting period; and constructing logic information according to the calculation sentences generated by the phrases and the judgment sentences generated by the conditional elements in the sentences to obtain IF [ report time < waiting period ] (payoff amount=basic insurance amount: 20%) and target input variables are report time, waiting period and basic insurance amount, and target output variables are payoff amount.
Fourth step: logic expression store and call: and numbering the obtained logic information according to the character string form and storing the logic information into a logic expression engine library, wherein the logic expression engine library can be a key-value database. When the method is needed, the logic information is called through the number, the logic information character string and the input and output variables are analyzed to generate logic information which can be used for calculation after analysis, and the logic information comprises a logic calculation expression, a target input variable and a target output variable.
After receiving a call request for obtaining a logic relationship, the logic expression engine library invokes and analyzes target logic information corresponding to the target number to generate and obtain logic information constructed according to different service types, which specifically includes, but is not limited to, taking a pseudo code form as an example and can be expressed as:
input report time, waiting period, basic insurance amount
if report time < waiting period then
Payoff = base insurance amount 0.2
output payoff amount
The Input is a target Input variable, the output is a target output variable, the if report time < waiting period then, the payoff=the basic insurance amount is 0.2, and the logic expression is obtained.
The above-described embodiment is merely an example, and is not limited in any way in this embodiment.
