We describe the automatic knowledge acquisition for representing the words of natural language phrases using significance vectors and the learning of filtering of phrases according to ten different domain classes. We particularly focus on examining the filtering performance under noisy conditions, that is the degradation of these filtering techniques for incomplete phrases with unknown words. Furthermore, we show that this technique already scales up for a few thousand real-world phrases, that it compares favorably to some classification techniques from information retrieval, and that it can deal with unknown words as they might occur based on incomplete lexicons or speech recognizers.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"11 3 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":"128996851","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}

This is true for most industries, although products and customer documentation requirements are frequently revised. The result is frequent documentation revision and significant labor costs. This paper describes a system to automate the generation of maintenance documentation for mechanical assemblies, the Automated Maintenance Manual Production (AMMP) system. Product and customer requirement revisions are accessed from a central database. For a given maintenance task, a spatial planner module derives a sequence of operations to carry out the task based on the product CAD definition. A presentation manager module converts this sequence into formatted text and illustrations.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"16 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":"126795109","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}

This paper describes a knowledge based brain CT scan interpretation system that uses the blackboard model to integrate various sources of knowledge. The frame-based representation technique is employed to represent the geometric model of the human brain. The knowledge on low level image processing algorithms and high level interpretation is partitioned into knowledge sources (KSs) that operate on and communicate through the domain blackboard. Several numeric image processing algorithms are coded into KSs that segment the images or extract features from the image primitives. For the mapping of image primitives to brain objects, there are two groups of mapping KSs, namely model-directed and data-directed. The system achieves the successful labeling and delineation of about 25 brain objects.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"96 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":"132338222","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}

Before you go from one place to another, you need to know a good route. In network theory, this is the shortest path problem. Dijkstra's algorithm is often used for solving this problem. However, when the road network of the city is very complicated and dense, which is usually the case, it will take too long for the algorithm to find the shortest path. Furthermore, in reality, things are not as simple as those stated in network theory. For instance, the cost of travel for the same part of the city at different times may not be the same. In this project, we have integrated Dijkstra's algorithm with a knowledge-based approach and case-based reasoning in solving the problem. With this integration, knowledge about the geographical information and past cases are used to help Dijkstra's algorithm in finding a solution. This approach dramatically reduces the computation time required for route finding. A prototype system has been implemented for route finding in Singapore.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"27 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":"114536458","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}

These activities frequently involve several database systems, user interfaces, and application programs. Traditional database systems do not support workflows to any reasonable extent. Usually, human beings must intervene to ensure their proper execution. We have developed an architecture based on AI technology that automatically manages workflows. This architecture executes on top of a distributed computing environment. It has been applied to automating service provisioning workflows; an implementation that operates on one such workflow has been developed. This work advances the Camel Project's goal of developing technologies for integrating heterogeneous database systems. It is notable in its marriage of AI approaches with standard distributed database techniques.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"1 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":"122749573","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}

For this purpose, FOCL and NDUBI/H, two systems that learn Horn clauses, have been employed. Several experimental results are reported and a critical view of the underlying independence assumption, made by almost all systems that learn from examples, is presented. This led us to redefine the problem of document understanding in terms of a new strategy of supervised inductive learning, called contextual learning. Experiments, in which a dependency hierarchy between concepts is defined, show that contextual rules increase predictive accuracy and decrease learning time for labelling problems, like document understanding. Encouraging results have been obtained when we tried to discover a linear dependency order by means of statistical methods.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"3 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":"126349425","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}

The system uses a form-independent validation engine and form-specific constraints to check that electronic forms are filled out correctly. If no errors are detected during validation, the system uses information on the form to generate a list of individuals and/or organizations that must approve it. The system, implemented in CLIPS and running on Macintosh computers, communicates with an off-the-shelf electronic forms package via AppleScript and can operate within the Apple Open Collaboration Environment (AOCE). The system has successfully validated and generated approval paths for approximately ten different types of forms, and is easily extended to new forms.<<ETX>>","PeriodicalId":297396,"journal":{"name":"Proceedings of the Tenth Conference on Artificial Intelligence for Applications","volume":"1 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":"126785468","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}
