15 . A display data generation method comprising: receiving input of target data including: a text sequence including texts, the texts being utterances that have occurred in chronological order or being arranged in sentences in arrangement order; and annotation information for each of the texts included in the text sequence; determining, depending on the annotation information for each of the texts, annotation expression information corresponding to each of the texts, the annotation expression information indicating how a display apparatus displays the texts; and generating display data for causing the annotation information for each of the texts to be displayed according to the determined annotation expression information.
16 . The display data generation method according to claim 15 , wherein the annotation expression information indicates a background to be displayed at a position and a range of a display screen of the display apparatus that correspond to each of the texts when the display apparatus displays the texts.
17 . The display data generation method according to claim 16 , wherein the target data further includes a sequence order being the chronological order or the arrangement order, the annotation information includes a classification label for each of the texts, the background includes a background color, and the generating generates, as the display data, data for causing the texts and the classification label for each of the texts to be displayed according to the sequence order.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 18/552,865, filed on Sep. 27, 2023, which application is a U.S. 371 Application of International Patent Application No. PCT/JP2021/013692, filed on 30 Mar. 2021, the disclosures of which are hereby incorporated herein by reference in their entireties. TECHNICAL FIELD The present disclosure relates to a display data generation device, a display data generation method, and a display data generation program. BACKGROUND ART An operator of a contact center is required to receive inquiry about products, service, or the like from customers or to provide support for solving issues of the customers. For the purpose of improving analysis of inquiry from customers and quality of reception, an operator creates a history of reception with customers and shares the history inside the contact center. Non Patent Literature 1 discloses a system that assists an operator by presenting appropriate information to the operator in reception on the basis of a business matter of a customer calling a contact center (call center). The system disclosed in Non Patent Literature 1 displays utterance texts of an operator and a customer on the left part of a screen, and displays, on the right part of the screen, an utterance text indicating a business matter of the customer or a similar question having a high score and an answer thereof among FAQs retrieved according to an utterance text for confirming the business matter by the operator. Furthermore, in Non Patent Literature 1, after a scene is estimated for each part of utterance, keywords are extracted only for a part of utterance of a predetermined scene, and FAQs are retrieved. (A scene is obtained by classifying an utterance text according to a type of the occasion in conversation between an operator and a customer. For example, a scene is obtained by classifying a flow in which the operator firstly says his/her own name, the customer talks about a business matter in calling, the operator confirms the business matter, confirms a contractor and contract content, then responds to the business matter, finally expresses gratitude, and ends the conversation into occasions including “opening”, “inquiry grasping”, “response”, “closing”, and the like. Such an estimation result of a scene is given as a label to an utterance text.) CITATION LIST Non Patent Literature Non Patent Literature 1: Takaaki Hasegawa and three others, “Automatic Recognition Support System That Supports Reception by Operator,” NTT Technical Journal, P16-19, 2019, vol. 31, No. 7 SUMMARY OF INVENTION Technical Problem In technique described in Non Patent Literature 1, a user refers to utterance texts of an operator and a customer, a similar question (having a high score of a FAQ automatically retrieved according to an utterance text for telling a business matter by the customer or an utterance text for confirming the business matter by the operator), and an answer thereof. However, a label such as a scene estimation result (annotation information) is not presented, and visualizing the annotation information so that a user can easily recognize the annotation information has been difficult. An object of the present disclosure made in view of the above issue is to provide a display data generation device, a display data generation method, and a display data generation program capable of visualizing annotation information. Solution to Problem In order to solve the above issue, there are included an input unit that receives input of target data including a text sequence according to the present disclosure and annotation information corresponding to texts included in the text sequence, and a display preparation unit that determines, on the basis of the annotation information, annotation expression information indicating a background color of a display screen of a display device and a position and a range in which a corresponding background color is displayed for expressing correspondence relationship between the texts and the annotation information in a case where the display device displays the texts, and generates display data for causing the text sequence and the annotation information to be displayed according to a sequence in the text sequence, the display data being for causing the background color indicated by the annotation expression information to be displayed at the position and the range indicated by the annotation expression information. Furthermore, in order to solve the above issue, a display data generation method according to the present disclosure includes a step for receiving input of target data including a text sequence and annotation information corresponding to texts included in the text sequence, and a step for determining, on the basis of the annotation information, annotation expression information indicating a background color of a display screen of a display device and a position and a range
