The following is further illustrated with reference to specific examples:
in an alternative embodiment, fig. 4 is a schematic diagram of an alternative logic expression obtaining method according to an embodiment of the present invention, and as shown in fig. 4, taking "if the reporting time is in the waiting period, we pay for the 20% of the basic insurance amount of the contract" as an example, the specific flow may include the following:
the first step is as follows: the logic expression engine design comprises logic expression elements and logic expression statement design: the logic expression elements are constructed into four types of elements including calculation elements, condition elements, numerical elements and variable elements. The logic expression engine is characterized in that the calculation elements and the condition elements are finite elements, namely, the logic expression engine can be exhaustive, the numerical elements and the variable elements are infinite elements, reserved words are set for the calculation elements and the condition elements according to the design of the calculation elements and the condition elements in the computer language, logic expression is carried out by matching the numerical elements and the variable elements, and the expression form is divided into a judgment statement and a calculation statement. For example, "if the time to report is within the waiting period, we pay the claim by 20% of the contract's basic insurance amount" as follows:
IF [ time of filing < waiting period ] (20% basic insurance amount of reimbursement amount)
The time "IF [ ] ()" is a judgment statement, "the reimbursement amount is 20%" of the basic insurance sum "and" the report time > the waiting period "are calculation statements, the calculation statements include variable elements, calculation elements and numerical elements, one of the calculation elements must link two elements which are variables or numerical values, and the judgment statement links a plurality of calculation statements.
The second step is that: constructing a logical expression trigger word lexicon; preprocessing such as word segmentation and part-of-speech tagging is carried out, the word segmentation needs to add trigger words related to computing elements and condition elements into a trigger word stock, the trigger words in example sentences are 'in …', 'if …' and '20%' are the trigger words added into the trigger word stock, and the construction process can be constructed in a named entity identification mode.
The third step: extracting a logic expression, namely extracting the logic expression by using dependency syntax analysis and rules: for the statement containing the logic expression, setting the statement to be extracted as the statement to be extracted with the condition element, and dividing the statement to be extracted into two calculation statements of 'report time in waiting period' and 'pay for the claim according to 20% of the basic insurance amount of the contract' according to syntactic analysis; performing logical expression extraction on a statement to be extracted according to a syntactic extraction rule constructed by constructing a dependency phrase structure tree and a trigger, taking ' report time in waiting period ' as an example, the dependency tree of which is as shown in fig. 4, mapping into ' in ' or ' in ' according to a calculation element ' in … ', judging as ' in this example, finding out the subject ' report time ' and the fixed term ' waiting period ' according to the dependency relationship in the dependency tree, and constructing a logical expression ' report time < waiting period '; logic information is constructed from a calculation sentence generated from a plurality of phrases in a sentence and a judgment sentence generated from a condition element, and IF [ report time < wait period ] (claim amount is 20% of the basic insurance amount), and target input variables are the report time, the wait period and the basic insurance amount, and target output variables are the claim amount.
The fourth step: logic expression storage and invocation: and numbering the obtained logic information according to a 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 logic information is needed to be used, 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, wherein the logic information comprises a logic calculation expression, a target input variable and a target output variable.
