TL;DR: We introduce DialGuide, a novel framework for controlling dialogue model behavior using natural language rules, or guidelines.

Abstract: Dialogue models are able to generate coherent and fluent responses, but they can still be challenging to control and may produce non-engaging, unsafe results. This unpredictability diminishes user trust and can hinder the use of the models in the real world. To address this, we introduce DialGuide, a novel framework for controlling dialogue model behavior using natural language rules, or guidelines. These guidelines provide information about the context they are applicable to and what should be included in the response, allowing the models to generate responses that are more closely aligned with the developer's expectations and intent. We evaluate DialGuide on three tasks in open-domain dialogue response generation: guideline selection, response generation, and response entailment verification. Our dataset contains 10,737 positive and 15,467 negative dialogue context-response-guideline triplets across two domains - chit-chat and safety. We provide baseline models for the tasks and benchmark their performance. We also demonstrate that DialGuide is effective in the dialogue safety domain, producing safe and engaging responses that follow developer guidelines.

Dialogue models are able to generate coher- ent and fluent responses, but they still be challenging to control and may produce non- engaging, unsafe responses. This unpredictabil- ity diminishes user trust and can hinder the the models in the real world. To address this, we introduce DIALGUIDE, a novel framework for controlling dialogue model behavior using natural language rules, or guidelines. These guidelines provide information about the con- text they are applicable to and what should be included in response, allowing the models be more closely aligned with the developer's expectations and intent. We evaluate DIAL- GUIDE on three tasks open-domain dialogue response generation: guideline selection, re- sponse generation, and response entailment ver- ification. Our dataset contains 10,737 positive and 15,467 negative dialogue context-response- guideline triplets across two domains chit- chat and safety. We provide baseline models for the tasks and benchmark their performance. Our results demonstrate that DIALGUIDE is effective in producing safe and engaging re- sponses that follow developer guidelines.

Figure Task setup- First, a conversational context, the model selects context relevant guidelines (Guideline and C the example) in Task 1. Then the model either generates a response using one of the selected guidelines (Guideline A) in Task 2 or checks whether response candidates follow the guideline in Task 3.
1 Introduction
We propose new framework, DIALGUIDE, to control dialogue response generation using natural language rules, which we call guidelines. A guide- line consists of an "if x" condition part specifying the context it is relevant to, and "then y" action part that specifies what the response should con- tain. Figure presents an overview of our frame- work. We use satrieee-then-iee infer process to re- trieve guidelines relevant to the context and then use one of them to either generate or verify a re- sponse candidate.
Current open-domain dialogue models such as Di- aloGPT (Zhang al., 2020), Blenderbot (Roller al., 2021), and PLATO (Bao et al., 2021) have shown the ability generate fluent and interesting responses. However, they are generally difficult to control and require large datasets to re-purpose them for a new task or domain. On the other hand, deployed conversational systems generally rely on handcrafted rules and templates (Tesauro et al., 2013; Ralston et al., 2019; Juraska et al., 2021; Konrád al., 2021; Chi et al., 2022). Such sys- tems allow for more control over responses and produce interesting, high quality responses, yet they are rigid and have poor coverage due to the difficulty of writing responses for every situation.
Using guidelines in our proposed framework of- fers several benefits. Guidelines allow developers to drive system actions towards predefined agendas, enhance response engagement, and address com- mon issues in system outputs such as the generation

of toxic responses. Guidelines can be added, re- moved, or edited during deployment, and updating them does not require retraining the model. Guide- lines are more flexible, as they are not as rigid as regex-based rules, but are more abstract. Our framework merges language models' instruction understanding with developers' intuitive guidelines expressed in natural language. It is important to note that the model's ability to generate responses is not limited solely to the guidelines present. In the absense of relevant guidelines, our models are trained to generate responses directly without con- ditioning on guidelines.
labels. While neural dialogue models are the main- stream in research, chatbots in deployment often still rely on handcrafted rules (Suendermann et al., 2009; Liu and Mei, 2020) and templates (Reiter et al., 2005; McRoy et al., 2003) due to the ease of update and ability to generate high quality, control- lable responses. There has also been progress in using natural language prompts and instructions to control models (Gupta al., 2022b; Mi et. 2022; Chung et al., 2022), but our work extends this by providing fine- fine-grained semantic control through guidelines over open domain response generation.
Fixing Models through Intervention Some recent work has explored editing models by computing tar- geted changes in the model's parameters (Sinitsin et al., 2020; Hase et al., 2021; Mitchell et al., 2021; Meng et al., 2022), while others have explored natural language feedback (Madaan et al., 2022; Scheurer et al., 2022; Zeidler et al., 2022). Our approach differs by showing that guidelines can be used to "patch" models by controlling their be- havior over problematic contexts and guiding the model toward the desired behavior, rather than mod- ifying the model's parameters.
In the DIALGUIDE framework", we benchmark three tasks: 1) Guideline selection, where model needs retrieve context-relevant guidelines, 2) Response generation, where a model generates a response that follows selected guideline, and 3) Response entailment verification, where the model determines whether a response follows or violates a guideline. We augment conversations from existing dialogue datasets- Blended Skills talk (Smith et al., 2020) and ProsocialDialog (Kim et al., 2022a) by collecting annotations of 1) relevant/ireeevant guidelines the conversation context and 2) re- sponses following/violating the guideline. To test the models' semantic understanding, we also cre- ate adversarial train and test sets. We establish benchmark performance on these tasks and show that models tuned on our data can generate better controlled and coherent responses. Although the dataset is mediuum-szzed few-shot based models en- able generalization to new guidelines and contexts. We also demonstrate our framework's 's effectiveness in the dialogue safety domain, generating safe and engaging responses.
Dialogue Safety is an important concern for con- versational models, as they can generate harmful content, exhibit social biases, and align themselves with offensive statements (Xu et al., 2021b; Ba- heti et al., 2021; Barikeri et al., 2021; Dinan et al., 2022). Several approaches have been proposed to address these issues, such as filtering unsafe text from training data (Xu al., 2021b; Ngo et al., 2021), using specialized decoding procedures for safer generation (Liu et al., 2021), and controlling language generation (Keskar et al., 2019; Dathathri et al., 2020). Other approaches include strategies for responding to problematic contexts, such as steering away from toxicity (Baheti et al., 2021; Arora et al., 2022), using apologies (Ung et al., 2022), and non-sequiturs (Xu et al., 202 Our work is closely related a study that proposed ProSocial dialog, a dataset where speakers disagree with unethical and toxic contexts using safety la- bels and social norms (Kim et al., 2022a). Using guidelines allows for more fine-grained control by specifying the contexts they are relevant to, and can provide more informative responses.
2 Related Work
Controlling Dialogue Systems has been focus of research to generate engaging responses (Ghaz- arian et al., 2021), prevent toxic content and bi- ases (Dinan et al., 2020; Xu et al., 2021a), steer the conversation towards specific keywords or top- ics (Tang et al., 2019; Gupta et al., 2022a), and ground responses in background knowledge such persona (Song et al., 2019), emotions (Zhong et al., 2019), or documents (Zhao et al., 2020; Li al., 2022). Many approaches train models on discrete labels or control codes, but this can be in- flexible and requires retraining to incorporate new

al., 2019; Gu et al., 2020). Response entail- ment (Welleck et al., 2019; Nie et al.. 2021: Gupta et al., 2022c) predicts whether a response entails a given premise. Our task design is similar, as we determine the entailment of a candidate re- sponse based on a guideline. This can be applied to response selection when multiple candidates are available and we need to select those that align with given guideline.
annotators are shown dialogue context and are asked to write guideline and then a response that follows the guideline. To aid the annotators, we provide hints in the form of small set of possible guideline phrases such as "ask a question about x" and "give a reason for doing x. Workers are pro- vided with multiple good and bad examples and are encouraged to use abstract concepts in the guide- lines to generalize to novel contexts. For example, using "learning a musical instrument" instead of "learning piano" in the condition generalizes the guideline to any musical instrument.
3 Proposed Task and Data collection
DIALGUIDE consists of the following tasks:
While in Mechanism annotators do not need to write responses, we notice that the written guide- lines can be specific the context and response. Mechanism 2, the other hand, yields more ab- stract guidelines due the use of guideline phrase hints. The set of context- gewdeeiine-esppooeee stances collected from this task is denoted as Gann-
Guideline retrieval: Retrieve the most appro-
priate guidelines relevant to the context.
Response generation: Generate response that follows the specified guideline.
Response entailment verification: Infer whether a response follows or entails the guideline or not.
in-
At test time, a model first retrieves a guideline most relevant to the context. Then, a model either generates a response based on the guideline(s) or checks whether a response follows the guideline(s).
B) Guideline relevance annotation task. For a given context C, workers are presented with set of guidelines Ge (g1, 92, -.gk) (only the condition part), and are asked annotate which guidelines are relevant the context. The annotation interface is displayed in Figure 3. We collect three anno- tations per context- -uuieet-gu pair (inter-annotator agreement of Krippendoff's alpha 0.67), and the majority label is chosen. To generate the guideline candidates, we first train a guideline generation model Mg using the InstructDial model (Gupta et al., 2022b), which is instruction tuned for the guideline generation task. The model is trained on a pair of contexts and responses using annotations from the guideline writing task. Using Mg. a large set of synthetic guidelines GBST is generated, con- ditioned on the contexts and responses from the BST train dataset. For each context C, the set of guidelines Ge is created by retrieving the top 5 highest scored guidelines from BM25 as well from DPR (Karpukhin et al., 2020) using context- guideline similarity. The DPR model is trained using the context-guideline pairs from GBST. The guideline set G, for context C' thus composed of 10 guidelines, where we replace a randomly se- lected retrieved guideline with the gold guideline from Gann written by the human annotators.
We collected two datasets for DIAL.GUDE.. For DIALGUIDE-BST, we augment conversations from the BlendedSkillTalk (Smith al., 2020) (BST) dataset. We use the Amazon Mechanical Turk plat- form to collect annotations for the three tasks men- tioned above. We use Blenderbot (Roller et al., 2021) to generate 3 additional responses for each context, creating a set of four responses including the original response from the dataset, denoted as Rg, which is used in tasks A) and C) below. D1- ALGUIDE-SAFETY consists of data for the safety domain, where we augment conversations from the ProsocialDialog (Kim et al., 2022a) dataset.
A) Guideline writing task. We collect annotations in the form of triplets g, where C' is the di- alogue context, g is a guideline that describes the context and the content of the responses, and Tey is a response that is coherent with the context and fol- lows the guideline. The annotations are collected using two mechanisms: In mechanism J, annota- tors are shown dialogue context and a response and are asked to write a guideline such that the provided response can be generated based on the guideline. The response shown is selected from Re (either the original dataset or the of automati- cally generated responses) with equal probability. Figure of Appendix B, we show the annota- tion interface for mechanism 1. In mechanism 2,

For all Dial* baselines, the guideline is concate- nated to the dialogue context and the response can- didate, with an instruction to perform entailment.
This is binary classification task to predict whether a response follows the provided guide- line. We experiment on the train, dev and test sets DIALGUIDE- -BST with 14689, 4406 and 4962 context-response pairs, as shown Table 1. Two settings are used: 1) Normal, where we only use the Positive and Negative instances, and 2) Adversarial, which additionally consists of adversarial negative responses (described in Section 3). We report the F1 scores per class, macro F] and accuracy. We explore the following models and baselines:

The results are shown in Table 4. Token-overlap and DNLI models perform poorly the task, in- dicating the need for models with capabilities be- yond token-level overlap for semantic similarity measures. DialTO multi-task pretrained models also struggle in the zero-shot setting. Our model BSTGuide shows the best performance, with 90.2 macro Fl score on the Normal test set. Perfor- mance drops on the Adversarial test set (87.5 macro FI), confirming the difficulty of the Adversarial test set. However, the performance drop is lower than on BSTGuide-NoAdv, which was fine-tuned with- out adversarial examples, indicating that training on a few adversarial examples improves robust- ness.

RS-entail measures response- guideline enatilment using the BSTGuide model. An ideal model would have high RS-entail and low Gd-Bleu-2 scores to avoid excessive guideline copying. Coherence is measured using Bert-large model trained on a mix of conversations from the DEB dataset (Sai et al., 2020), BST, and Proso- cial dialogue. It takes the context and response as input and predicts the coherence of the response. In addition, we conducted human evaluation on Mturk platform (more details in Appendix B) on 100 randomly selected test instances. They anno- tate if the response is coherent and sensible (Resp, quality), the guideline's 's quality (Gd-quality), and if the response follows the guideline (Entailment).
This task involves generating a response r that fol- lows the provided guideline g and is coherent to the dialogue context C. We experiment on the test set of DIALGUIDE- BSST with 1507 context- guideline-response triples. For training we ex- periment with both DIALGUIDE-BST and DIAL- GUIDE-SAFETY train sets. Most of our baseline models are instruction-tunen -uneed,, and we feed the fol- lowing sequence as input to the models: an in- struction generate response conditioned on the guideline and the context, followed with the guide- line and the dialogue context. We consider the following methods and compare to Ref-responses (the reference or gold responses from the data set).

The DIALGUIDE- model, trained on multiple dialogue tasks, performs slightly better than its Bart-guideline-tume on most metrics and is better at response quality and coherence among all models. It also performs better than BST-onll, indicating that models can improve with more and diverse data and guidelines. While the No-guideline model has good coherence, our model offers more control over the generation space. The Multistep model that generates guide- lines first followed by responses, suffers on quality but offers an interpretable generation approach.

The exper- iment is carried out for response generation results on DIALGGIDE-BBT data. As we increase the noise percentage, the response quality and coher- ence improve, but at the cost of guideline entail- ment. For both retrieval thresholds, 20% noisy data augmentation leads to best coherence, with small trade-off in guideline entailment. After 20%, we decrease in both coherence and entailment, and hence select 20% noise for Ret-robust model in our main experiments.

forms zero-shot generation forms poorly on safety. SaulBartO-wihhuudelli which conditions on guidelines in zero-shot set- ting, improves safety by 5% in automatic and 6% in human evaluation. The OPT30B- generates guideline-conditioned responses, but per- forms poorly in terms of safety and coherence com- pared to other baselines. The Dialbart-rol baseline, which uses RoTs or rules of thumbs (such as "it is bad to be racist"), performs similarly to DIAL- GUIDE-tuned on safety. However, ROTs do not contain the "if condition", thus making selection of relevant ROTs harder at test time. In addition, RoTs are often very generic which leads poor control, as evident by the lower entailment scores. Human evaluation shows that DIALGUIDE-tuned outperforms all other baselines on three criteria. We perform ablation experiments with our model. The No-guidelines baseline, which is trained on safety data without guidelines or RoTs, can generate safe responses but it lacks control. whereas DIAI.GUIDF--uned sponses based on the developers' agenda. Although the Safety-only baseline trained exclusively on DI- ALGUIDE-SAFERS performs better than BST-only, the performance of BST-only close, which im- plies that a model that uses guidelines can perform well on cross-domain settings.

For the safety domain, we also include Safety metric that scores whether a response is safe. The safety classifier is a Deberta-large classifier trained on the BAD (Bot Adversarial Dialogue) dataset (Xu et al., 2021a), consisting of dialogue safcty data col- lected through adversarial framework. We con- ducted human evaluation on the Mturk platform on 100 randomly selected test instances (more details in Appendix B). Workers annotated whether the response is coherent and sensible (Resp-quality),

elaborate on the guideline, while OPTsoB-fewshot produces a less interesting response. The multi- step baseline's generated guideline and response focus on the topic of news channels and the re- trieval baselines' responses follow the retrieved guideline and are coherent. In the bottom exam- ple, the gold guideline provides response related to the speaker's previous friendships. DialGuide- tuned's output follows the gold guideline similar to the gold response, but the OPT30B fewssho model output is unrelated and instead expresses a desire to have friends. The multistep baseline generates a guideline and response that focuses on parenting, while the Ret-generate response focuses too much on the provided guideline and is somewhat inco- herent; Ret-robust is able to incorporate both the context and guideline.
els trained on DialGuide data generate coherent, diverse, and safe responses that generalize well new guidelines and contexts.
7 Limitations
Our work explores aligning and controlling dia- logue models toward developer-defined natural lan- guage guidelines. There is room for improvement in the following aspects: DialGuide may not be able to handle very complex nuanced guidelines. For example, it may struggle to interpret guidelines that contain multiple conditions or that require a high level of common sense or domain knowledge. The performance of DialGuide may depend on the quality and clarity of the guidelines it is provided with. If the guidelines are poorly written or am- biguous, the system may struggle to interpret them correctly and generate appropriate responses. Dial- Guide may be less effective in domains where the appropriate response is more subjective or open interpretation. For example, in a customer service context, may be difficult define clear guide- lines for handling every possible customer request or complaint. DialGuide may not be suitable for use in all types of dialogue systems. For example. it may be less effective in systems that require more flexibility creativity in generating responses. Di- alGuide may be more resource-intensvve than other approaches dialogue modeling, as it requires the additional step of matching generated response with a set of guidelines or generating a guideline. Our work an initial step in controlling dialoguc models through guidelines and aligning them with developer agenda. Future work can explore Di- alGuide for new applications and domains, such as task-oriented settings. Since response selection and generation can suffer from semantic overlap biases with the guidelines, better pretraining and incorporating commonsense knowledge should be able to help. Future work may also incorporate more complex and logical "if" condition matching.
In Table (Appendix A), we show examples for DIAL.GUDDE-SAFTTY. DialGuide-tue fol- lows the guideline and generates safe responses, while SallBartO-nouudder sponses. The No-guideline model, which is trained safety response data without guidelines, gener- ates safe responses but inferior the DialGuide- tuned responses. The RoT based responses are more generic and less specific than DialGuide- tuned responses.
generates generic re-
Overall, the model outputs show range of qual- ity, with some following the gold guideline more closely than others. Although DialGuide- has the best performance in both results and qualitative analysis and forms a performance upper-bound us- ing the gold guidelines, the retrieval baselines also show good performance and are more practical, as systems need to retrieve relevant guidelines at test time. The Multistep baseline is also useful in sce- narios where good guideline is available, as the model can first generate guideline on how it is going respond and then generate the response.
6 Conclusion
DialGuide framework and dataset provide a solu- tion for controlling dialogue model behavior using natural language rules, or guidelines. Through the three tasks of guideline selection, response gen- cration, and response entailment verification, Di- alGuide aims to enable better control of dialogue models and improve their trustworthiness and real- world use. We evaluate DialGuide on two domains, chit-chat and safety, and provide baseline models and benchmark performance for these tasks. Mod-
Ethies
The choice of guidelines for a particular dialogue system will depend on the intended use and goals of the system, as well as the preferences and values of the developers and stakeholders. There is risk that the selection of guidelines may be influenced by human biases or subjective judgments of the developers or stakeholders.

that are misleading, incorrect, manipulative, or harmful users. For example, the system could be used to generate responses that exploit users' vul- nerabilities or manipulate their emotions for com- mercial or political gain. The system may he used to collect sensitive or personal information about users, which could raise privacy concerns if this information is not handled appropriately. Careful regulation and oversight are needed to mitigate ill use of the system.

the guideline based response selection task, and in Figure 5, we show the annotation interface for the adversarial response writing task. In all annota- tions, we employed Amazon Mechanical Turk. In each interface, we provided detailed instructions and explanations for the task along with 3 or more example instances and their annotations. The re- quirements for workers/annotators who worked on these tasks were number of tasks completed more than 1000, first language English, HIT approval rate higher than 98 percent, and we used Master workers. They were paid higher than an average of $15 per hour. We collected the data across multiple batches and regularly removed the workers who either had poor agreement with other workers or who performed poorly based on our manual checks. We removed the annotations of such workers and recollected annotations for those instances.

Annotations for dataset quality- We conducted human evaluations to test the dataset quality (dis- cussed in last paragraph of Section 3). For 200 ran- domly selected context-guidellie-rrsposss triplets, we asked the annotators to provide binary ratings for the following questions - a) Sensible response (yes-no): Is the response sensible? Does it make sense as a follow-up to the conversation? b) Sensi- ble guideline (yes-no): Is the guideline sensible in itself?, e) Relevant guideline (yes-no): Is the guide- line relevant to the conversation?, and d) Response follows guideline (yes-no): Does the response fol- low the guideline? We collected 3 annotations per instance and report the average scores.

Annotations for human evaluation For hu- man evaluation of response generation and Dia- logue safety response generation, we hire annota- tors from the Amazon Mechanical Turk platform. The selection criteria are the same as described above for data collection. For the DIALGUIDE- BST Response generation human evaluation (Scc- tion 4.3.3), we collect annotations for 100 randomly selected instances of the test set, and perform an evaluation of responses from 7 models. We ask the annotators to score model responses and guidelines on the following criteria- a) Response quality (yes- no): Is the response sensible and coherent? Does it make sense as a follow-up to the conversation? b) Relevant guideline (yes-no): Is the guideline relevant to the conversation?, and c) Entailment (yes-no): Does the response follow or entail the guideline? For the DIAfGU response evaluation (Section 4.4.2), we collect annotations

We have mentioned this in the footnote on page 2, and we will add a link in the final version of the paper.\n\n\n> *Regarding the use of prompts and our contributions*\n\nWe agree that prompting-based approaches have gained widespread acceptance within the NLP community, and our work, DialGuide, certainly builds upon this well-established area of research. However, DialGuide elevates the concept beyond using static prompts for enhancing model performance. While traditional methods typically employ a limited set of static prompts across varying contexts, DialGuide is engineered to dynamically fetch the most relevant and context-appropriate guidelines and use them as prompt. This adaptability addresses a significant limitation of traditional prompting techniques, which often struggle to adapt to complex, ever-changing scenarios. In stark contrast, DialGuide's adaptive prompting mechanism facilitates more nuanced, controlled, and coherent responses, uniquely tailored to specific contexts.\n\nBeyond these points, we offer the following unique contributions that differentiate our work:\n* Novel Framework and Data: We introduce DialGuide, a novel framework designed to control dialogue model behaviour using natural language rules or guidelines. This is not merely an application of existing prompting techniques but a comprehensive framework that aims to solve a more complex problem.\n* Modelling Contributions: Our work decomposes the task into three distinct sub-tasks:\n    1. Guideline Retrieval: Identifying the most appropriate guidelines relevant to the context.\n    2. Response Generation: Creating a response that adheres to the selected guideline.\n    3. Response Entailment Verification: Assessing whether the generated response is in alignment with the guideline.\n* Benchmark and Results: We establish a robust set of baselines and benchmark performance on these tasks. Our results demonstrate that models trained on our dataset can generate more controlled and coherent responses.\n\n\nWe hope that this addresses your concerns.

We appreciate your feedback and will address your concerns in the following rebuttal.\n\n> Regarding Transferability\n\nGuidelines in our framework are expressed in natural language, leveraging the instruction-following capabilities of recent language models. This suggests that the guidelines should be transferable to other domains and tasks.\nTo support this claim, we conducted an experiment in which we fine-tuned a model on the DIALGUIDE-SAFETY dataset and then evaluated it on the DIALGUIDE-BST dataset. The results (last row of Table 7) showed that the model was able to retrieve guidelines and generate responses that were coherent, diverse, entail the guidelines and are safe. This suggests that the guidelines are transferable to other domains, even if they are not explicitly trained on those domains. It's also worth mentioning that throughout our experiments (as shown in Tables 3-8), the test sets only contain unseen guidelines and contexts. The consistently strong performance of our models across these novel scenarios further validates their ability to generalize effectively.\n\nHowever, we acknowledge a potential limitation: while our framework is designed to be broadly applicable, the guidelines in our current dataset may not fully generalize to significantly distinct domains. In such cases, additional domain-specific guidelines would likely be needed to ensure optimal performance. Fortunately, our framework allows for the easy incorporation of new guidelines, and finetuning on only a few additional guidelines can suffice for adaptation to new domains.\n\n\n> *Regarding Task Specificity and General Dialogue Systems -  performing badly on this dataset does not necessarily mean it is a bad dialogue system.*\n\nIt's important to note that our dataset and task design focus on specific capabilities, such as guideline adherence, which may not be the sole metrics for evaluating the efficacy of a general dialogue system. A model that underperforms on our dataset may still excel in other dialogue scenarios that require different skills or abilities. Our tasks aim to offer a focused evaluation on aspects like safety and guideline adherence, and should not be viewed as a comprehensive assessment of a dialogue system's overall quality.\n\n> *Regarding - The reported results look decent enough, thus not sure whether recent models would seriously struggle with the task especially if they are fine-tuned on this dataset.*\n\nWe acknowledge that recent models are likely to exhibit strong performance. However, the value of our framework lies in its ability to further improve the alignment and safety of these already powerful models. By integrating them into our DialGuide framework, we can leverage their instruction following capabilities while ensuring that the generated responses are not only coherent and diverse but also adhere to specific guidelines for safety and context-appropriateness. Thus, our framework serves as an additional layer that enhances the utility of recent models in dialogue systems.\n\n> Regarding Adversarial Test Set Performance\n\nWe'd like to clarify the naming and composition of our adversarial test set. In Table 1, the Dialogue-bst test set for entailment verification comprises 1507 positive, 2465 negative, and 990 adversarial negative instances. The normal test set is evaluated using the 1507 positive and 2465 negative responses, while the adversarial test set in Table 4 includes 1507 positive, and both the 2465 negative and the 990 adversarial negative responses. Unlike the adversarial test set in Nie et al., which only contains adversarial instances, ours is a mix of both normal and adversarial negatives. Consequently, the performance drop in our setting will be more pronounced if evaluated solely on the adversarial negatives. To avoid confusion, we will rename \"adversarial\" to \"hard test set\" in the final version. We want to add that we are using more recent language models such as T0 compared to Nie et al which used Roberta. These LMs are better at handling adversarial instances, which is why the performance drop would not be as significant.\n\n> Regarding Length of Dialogue History\n\nThe dialogue history is truncated to a maximum of 1024 tokens (truncation from the left), achieved by concatenating previous utterances. We remove utterances which make the context go longer than 1024 tokens.\n\n> Regarding Generalisation Experiments\n\nIn all of our results (Table 3-8), the test set consists of both guidelines and contexts the model has not seen during training. We show the performance of models and baselines on novel contexts and guidelines and the results show that our models generalize well to them. These results show the our models get above 90% coherence and safety, and around 90% guideline entailment score on novel guidelines and contexts. Furthermore, as we mentioned above, the last row in Table 7 shows the cross-domain transfer performance of our model, where a model trained on BST data performs well on safety domain contexts and guidelines.\n\n\n\nWe hope that this addresses your concerns.

Since the task design is specific, it is not easy to transfer the knowledge acquired in this task to a more general type of dialogue system. Even if it is more for a specific design of dialogues, something that can inherit the way to generate a response in inference, the dataset may not be helpful since the covered domain of the dialogues is limited and may not overlap at all. On the other hand, since the task setting is different from the common dialogue response generation and requires some other abilities, performing badly on this dataset does not necessarily mean it is a bad dialogue system. \n\n2.

We agree that this could be an interesting approach for further validation and efficiency. \n\n> *Since you're using an instruction-tuned model, why not train the model with the mix of A B C tasks. It is recommended to try to accomplish all three tasks using a single model.*\n\nWe appreciate your recommendation to train a single model for all three tasks. We agree that using a single model for multiple tasks is more practical and efficient, particularly in real-world applications. Your suggestion is in line with broader trends in multi-task learning and model efficiency. While we did explore multi-task learning in our preliminary experiments, we didn't find significant performance improvements, which is why we chose not to include it. Nonetheless, we acknowledge its potential for enhancing efficiency.\n\n> *Maybe some security should be considered, if some malicious guideline is set up, can this model defend against it?*\n\nWe have discussed this point in the limitation and Ethics section. As a practical solution, apart from developing policies for writing guidelines and human oversight, one could use toxicity classifiers as an automatic solution.\n\n> *Why did some tasks use only the Dialguide-BST dataset?*\n\nFor guideline entailment verification, we focused solely on the BST domain due to data collection costs and the promising preliminary results showing that a model trained on BST generalizes well to novel contexts and guidelines.\n\n\n> *No experiment to validate the generalization of guidelines.*\n\nIn response to the concern about the generalization of guidelines, we did conduct an experiment in which we fine-tuned a model on the DIALGUIDE-SAFETY dataset and then evaluated it on the DIALGUIDE-BST dataset. As shown in the last row of Table 7, the model exhibited the ability to retrieve guidelines and generate responses that are coherent, diverse, and safe, while also entailing the guidelines. This experiment suggests that our guidelines have a degree of transferability across different domains, even those not explicitly trained on. In all of our results (Table 3-8), the test set consists of both guidelines and contexts the model has not seen during training, showing good generalization to novel contexts and guidelines.\n\nHowever, we acknowledge a potential limitation that you and we have both considered: while our framework is designed to be broadly applicable, the guidelines in our current dataset may not fully generalize to significantly distinct domains. In such cases, additional domain-specific guidelines would likely be needed to ensure optimal performance. Fortunately, our framework allows for the easy incorporation of new guidelines, and only a few additional guidelines can suffice for adaptation to new domains.\n\n\n> Question - *Why are you using InstructDial as a base model instead of better instruction-tuned models like Vicuna?*\n\nWe used InstructDial as our base model because it is the most relevant open-sourced model that has been instruction-tuned on a large collection of dialogue tasks. InstructDial has state-of-the-art performance on a variety of dialogue tasks, which suggests that it is well-suited for our task of generating responses that follow guidelines.\n\n> Question - *Why do you use DialT0 in the task Response Entailment Verification, but DialBart0 in the task Response Generation?*\n\n\nWe chose to use DialBart0 for the task of response generation because it has been shown to be as good as DialT0 at generation, while DialT0 is better at classification tasks. Additionally, text generation inference is much cheaper on the smaller DialBart0 model compared to the much larger DialT0 model.\n\n\nWe hope that this addresses your concerns.

Author rebuttal:

Meta-review: The authors introduce a new dialogue task called DIALGUIDE and provide a human-annotated dataset for this task. The experiments conducted in the paper demonstrate that fine-tuning a model on the DIALGUIDE dataset can improve the model's ability to generate coherent, diverse, and safe responses.  The experimental results indicate promising outcomes in terms of response quality and safety.
