In this paper, we propose a KBQA solution based on attribute graph. It extracts the mentions in text to recognize relations and entities, and transforms it into a slot-filling Cypher statement to query the answer. Meanwhile, we design a two-layer network based on a structural attention mechanism to optimize entity boundary identification. The solution provides new ideas of relation recognition for answering complex questions over attribute knowledge graph. Experimental results show that the proposed approach achieves promising performance on both CCKS2019 public dataset and the self-built vertical domain dataset.","PeriodicalId":278114,"journal":{"name":"Proceedings of the 2021 9th International Conference on Information Technology: IoT and Smart City","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125262992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Role of Mobile Applications For Development Community Enterprise In The Pandemic Period","authors":"Jirawan Plungpongpan, Supparang Ruangvanich","doi":"10.1145/3512576.3512616","DOIUrl":"https://doi.org/10.1145/3512576.3512616","url":null,"abstract":"∗ This paper aimed to investigate the role of mobile applications in the development of community enterprises during the pandemic. The application was a marketing tool that sent personalized promo-tions to apps embedded in mobile devices based on a community enterprise in Noen Kham, Chainat. Situated analytics (SA), a com-bination of location-based and analytical interaction, can improve customer understanding. This study developed a mobile application (app) called WeaveApp, which uses SA to present product information on mobile devices to assist consumers in making deci-sions during a shopping scenario. The WeaveApp was created to only scan the QR code of a contact’s seller with their smartphone’s camera. The helpful contact information will then be displayed on the smartphone screen, thanks to the concept of situated analytics. When designing and developing the mobile app prototype, an iterative process of design analysis, prototype development, and user interface evaluation was used. During the iterative process, the number of iterations was limited to three, and the data gath-ered during each iteration was used to improve the mobile app in subsequent iterations. After several iteration cycles, the final version of the WeaveApp was created. Every component, including the QR scanning system and the cloud database, was tested to ensure they functioned as intended. In a shopping environment, the effectiveness of the mobile app in assisting consumers in making a weave selection was evaluated. WeaveApp significantly increases customers’ success rate when selecting a weave product based on the findings. A tutorial on using the WeaveApp is one of the new features added to the app. When the mobile app is first launched, it can input special weave conditions, such as a new pattern, to provide a more personalized way of informing the customer about the weave products.","PeriodicalId":278114,"journal":{"name":"Proceedings of the 2021 9th International Conference on Information Technology: IoT and Smart City","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121585898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
