Publication number: 20230054146Abstract: An analysis system is configured to include an extraction unit, an output unit, an acquisition unit, and a dictionary generation unit. The extraction unit extracts, as a token pair, two tokens that consecutively occur in a sentence separated using the basic dictionary. Regarding a token in which two tokens included in a token pair are connected, the output unit displays a selection screen for selecting any of registering with a dictionary, registering with an on-hold list for holding registration with the dictionary, and not registering with the dictionary. The acquisition unit acquires a selection result for the selection screen. The dictionary generation unit generates an on-hold list with which the token pair whose selection result indicates on-hold is registered as a token, and a dictionary with which the token pair whose selection result indicates registering is registered as a connected token.Type: ApplicationFiled: August 10, 2022Publication date: February 23, 2023Applicant: NEC CorporationInventors: Taizo Shibuya, Kentaro Nishida, Kiri Inayoshi, Tomo Tanaka
