The towers were the primary distinguishing feature of Ubar and are the strongest proof that this is in fact Ubar, which is described in the Koran as “the many-towered city. At each corner stood a tower, roughly 10 feet in diameter and 30 feet tall. The fortress, they found, was ringed by eight walls, each about two feet thick, 10 to 12 feet high and about 60 feet long. In times of trouble, the fortress served as a safe haven whose walls and towers were never breached. So the bulk of the “city” would have left few permanent traces, except for fire pits, which the team found in abundance.īut at the center of the tent city was a permanent fortress that served as the home of the king, as a processing and storage facility for the frankincense and as a record-keeping center. Most Arabs in the past have lived not in traditional dwellings but in tents whose sides can be opened to allow cooling breezes. What they found was not a city in the conventional sense. Ultimately, the weight of the city caused the cavern to collapse in a massive sinkhole, destroying much of the city and causing the rest to be abandoned. In building his “imitation of paradise,” the legendary King Shaddad ibn ‘Ad unknowingly constructed it over a large limestone cavern. Moreover, the researchers say they have documented how the city fell, and that it did not appear to be by divine retribution for wickedness. In a news conference today at the Huntington Library in San Marino, the researchers will announce that the site excavated over the past two months reveals an unusual eight-sided structure that must have been every bit as magnificent as it was portrayed in legend. ![]() Lawrence, better known as Lawrence of Arabia, called it “the Atlantis of the sands” and, like the undersea Atlantis, many scholars doubted that Ubar ever existed. We appreciate their open-sourcing such high-quality code, which is very helpful to our research.Īnd of course thanks HuggingFace for their wonderful transformers implementation.Ubar’s rulers became wealthy and powerful and its residents-according to Islamic legend-so wicked and debauched that eventually God destroyed the city, allowing it to be swallowed up by the restless desert. This code is adapted and modified upon the released code of previous AAAI 2020 paper "Task-Oriented Dialog Systems that Consider Multiple Appropriate Responses under the Same Context". A city 12 metres below the sands was uncovered by excavations. use_true_bspn_for_ctr_eval: use the ground truth belief span to query DB results. Ubar, could only be seen from space before excavations were made.use_all_previous_context: use all previous turns as context.use_true_curr_aspn: use the ground truth current turn's belief span.use_true_curr_bspn: use the ground truth current turn's belief span. ![]() use_true_prev_resp: use the ground truth previous turns' response as context.use_true_db_pointer: use the ground truth database search results as context.use_true_prev_aspn: use the ground truth previous turns' action span as context.use_true_prev_bspn: use the ground truth previous turns' belief span as context.Python train_DST.py -mode test -cfg eval_load_path=$path use_true_prev_bspn=False use_true_prev_aspn=True use_true_prev_resp=True use_true_db_pointer=False We use the tokenization tool in SpaCy which can be installed through: We also provide technical appendix in Appendix.pdf. The advantages of UBAR in modeling on a dialog session The transfer ability of UBAR to new domains with limitedĭata and provide visualization and a case study to illustrate Thorough analyses demonstrate that the sessionlevel training sequence formulation and the generated dialogĬontext are essential for UBAR to operate as a fully end-toend task-oriented dialog system in real life. The combined score of response generation, policy optimization, and end-to-end modeling by 4.7, 3.5, and 9.4 points respectively. State-of-the-art performances in multiple settings, improving Experimental results on the MultiWOZ datasets show that UBAR achieves States, system acts, and system responses. To user utterances and all content it generated such as belief In a more realistic setting, where its dialog context has access Of the entire dialog session which is composed of user utterance, belief state, database result, system act, and system response of every dialog turn. Specifically, UBAR is acquired by fine-tuning the large pretrained unidirectional language model GPT-2 on the sequence Which models task-oriented dialogs on a dialog session level. This paper presents our task-oriented dialog system UBAR This is the code and data for the AAAI 2021 paper "UBAR: Towards Fully End-to-End Task-Oriented Dialog System with GPT-2".
