We developed the Software requirement specifications(SRS) editor system with semantic information. Since this system have the semantic information, the engineer who takes charge of software requirement specifications and the engineer who takes charge of software test can reach shared understanding. Also, This system have the function which can find out the of description, the function which reuses the inputted the description, the function which shows the relationship of the descriptions. This paper describes that the sentence of SRS can be divided into six parts, 5W1H (Actor(Who), Time(When), Location(where), Reason(Why), Object of target(What)), and SRS has the tag which 5W1H are written as semantic information. This paper also describes how to give the degree of requirement, and describes the methods to have the tag which the degree of requirement is written as semantic information. This paper describes the SRS editor system with semantic information, and describes the function which can find out the of description, the function which reuses the inputted the description, the function which shows the relationship of the descriptions.
