This paper presents the first use of the Taxis environment to design a real engineering project information system after the Taxis compiler was implemented. It shows that the use of the Taxis environment and methodology has effectively and efficiently led to the development of a new management system which offers a natural correspondence between the system and the real world, and provides suitable responsiveness, thus overcoming the shortcomings of the previous engineering system, which was developed using traditional tools and methods. This experience of this study is valuable for the development of information and engineering systems.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126314554","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}

HKBs provide a uniform framework for integrating uncertain information (as is often the case in terrain reasoning), temporal information (needed for weather effects, etc.), and numeric constraint solving capabilities (for situation assessment). We show how the HKB formalism may be applied to solve the problem of placing Patriot and Hawk missile batteries in a specified terrain, subject to the requirement that various existing assets be afforded maximal protection. We formalize this problem in a clear, mathematical framework, using the HKB paradigm, and show how the problem is solved. This provides a mathematically sound, as well as a practically viable, scalable solution to the important problem of missile siting.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132510470","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}

However, current TKR systems are unable to represent temporal patterns or recognize instances of such patterns from ongoing observations. Motivated by applications such as service personnel dispatching, and plan recognition for interactive user interfaces, we extend TKR by introducing terminological QME (qualitative, metric and equality) networks. In QME networks, nodes are TKR concepts and arcs are qualitative constraints between temporal intervals associated with nodes, metric constraints between end-points of temporal intervals, and equality constraints among roles of different concepts. We use QME networks to represent patterns, and define QME network subsumption, which enables us to organize a pattern library into a taxonomy. We also develop a terminological approach to predictive pattern recognition based on subsumption and a related notion of compatibility. We assign a modality of \"necessary\", \"optional\" or \"impossible\" to every pattern as events and constraints are observed. We also show how to augment a pattern library for complete recognition. This work, implemented in the T-REX system, enables more sophisticated applications of TKR technology.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132994378","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}

They provide a basis for probabilistic inference, to calculate the changes in probabilistic belief as new evidence is obtained. However, their use in real problem domains is hampered by the difficulties facing the construction of such belief networks, particularly in domains where neither sufficient data nor human expertise is available. In this paper, we show that this problem can be circumvented by exploiting knowledge from existing mathematical models. An application of belief networks to assess the impact of climate change on potato production is used as an illustration. We show how the uncertainty of future climate change, variability of current weather and the knowledge about potato development can be combined in a belief network, which provides an aid for policy makers in agriculture. The model is tested using synthetic weather scenarios. The results are compared with those obtained from a conventional mathematical model.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124954526","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}

Despite these successes, most similarity measures used in the current literature are defined on limited feature types. Therefore, these similarity measures cannot be applied to the database environment due to the variety of data types that exist. In this paper, we propose a new method of similarity-based learning for databases using information theory. The current similarity measures are improved in several ways. Similarity is defined on every attribute type in the database, and each attribute is assigned a weight depending on its importance with respect to the target attribute. Besides, our nearest neighbor algorithm gives different weights to the selected instances. Our system is implemented and tested on some typical machine learning databases. Our experiments show that the classification accuracy of our system is, in general, superior to that of other learning methods.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134258935","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}

DANA, a multimedia network monitoring system, has profited by using knowledge sources to implement a policy of guaranteed update consistency. Project X, a real-time passive radar system, has used knowledge source independence and the flexibility of opportunistic control to support easy experimentation with new system designs. Along with the benefits, we learned several lessons about the difficulties and pitfalls of blackboard systems. First, opportunistic control is hard to implement, maintain, and sell to managers. Second, knowledge sources are never as neat as they first appear. Finally, it is important to treat blackboards as a programming philosophy and not an architectural mandate.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133881810","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}
