Data querying system and method

A database querying method, comprising the steps:

• a) receiving, by an input interface unit, textual input and converting the textual input into a textual data string;
• b) obtaining, by a sequencing unit, at least one key phrase from the textual data string;
• c) obtaining, by the sequencing unit, for each of the at least one key phrase a set of all contiguous sequences of words of the respective key phrase;
• d) accessing, by a classification network unit, a semantic network (SN) for each of the contiguous sequences of words, and setting a classification flag for the respective contiguous sequence of words, if the semantic network (SN) contains a link between the respective contiguous sequence of words and an entry in a predetermined classification database (CD);
• e) accessing, by a comparison unit, a predetermined target database for each of the contiguous sequences of words, and setting a target flag for the respective contiguous sequence of words, if the predetermined target database contains at least one entry matching the respective contiguous sequence of words;
• f) outputting, by an output interface unit, at least one contiguous sequence of words and information relating to whether at least one of the respective target flag and the respective classification flag has been set.

A non-transitory storage medium containing computer-readable instructions that, when executed by a computer, cause the computer to:

• a) receive, by an input interface unit, textual input and converting the textual input into a textual data string;
• b) obtain, by a sequencing unit, at least one key phrase from the textual data string;
• c) obtain, by the sequencing unit, for each of the at least one key phrase a set of all contiguous sequences of words of the respective key phrase;
• d) access, by a classification network unit, a semantic network (SN) for each of the contiguous sequences of words, and setting a classification flag for the respective contiguous sequence of words, if the semantic network (SN) contains a link between the respective contiguous sequence of words and an entry in a predetermined classification database (CD);
• e) access, by a comparison unit, a predetermined target database for each of the contiguous sequences of words, and setting a target flag for the respective contiguous sequence of words, if the predetermined target database contains at least one entry matching the respective contiguous sequence of words;
• f) output, by an output interface unit, at least one contiguous sequence of words and information relating to whether at least one of the respective target flag and the respective classification flag has been set.
