There is thus a need to improve the human-system interface for this kind of application. A graphical query language is presented for an information retrieval system. The language allows the user to state elementary queries by means of small images representing catalog cards. The Boolean combination of elementary queries is intuitively achieved by positioning the cards on the screen. This approach lets people use familiar concepts while attempting to achieve better utilization of the information retrieval system.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128906620","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}

A spatial parser for visual languages whose syntax is specified by a picture layout grammar was implemented. This parser forms the basis of a visual programming environment.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129188160","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}

In earlier work (see E. Jungert and S.-K. Chung, Proc. IFIP TC-2 Working Conf. on Visual Database Systems, Tokyo, Japan, 1989) an algebra based on symbolic projections for manipulation and transformation of symbolic images has been defined. Although that symbolic algebra was quite powerful for manipulation of symbolic images, it did not include any means for spatial reasoning. With such a goal it was already clear at an early stage that the algebra had to be developed further. A description is given of the unification of algebraic expressions, which offers a powerful basis for spatial reasoning. It is shown that the algebra constitutes a basis for a tool for spatial reasoning in symbolic images.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116270101","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 generic character of the setup enables the students to easily incorporate their own procedures within the tool.

Forms/2 treats iteration in a form as a temporal sequence of instances of the form. Termination is controlled rather uniquely in Forms/2 as a direct result of the dependence-resolution evaluation mechanism.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"75 2 Suppl 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128456106","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 paper presents a visual interface that addresses these two issues, and that in turn leads to a hew user interface metaphor. The interface is to a set of cooperating expert systems that acts as a non-intrusive, intelligent assistant in the conceptual data modelling phase of database design. The user interface allows the designer to simultaneously work at the abstract level and at the detail level while building the enterprise model from which the database will be generated. The key features of the interface are graphical gestural input, and the spatial maintenance of logical context through a technique of information filtering, using a structure of hierarchical windows. Planned extensions to the interface include user manipulation of a 3-D representation of extended entity-relationship diagrams, interactive control of behavior modelling animations, and the ability to deal with several models at the same time.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121440585","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}

In order to address this problem, the authors propose a visual language for the acquisition, display and debugging of this plan knowledge. The basis of this language is a model of the user's view of tasks, supported by a series of psychological experiments. DACRON supports the acquisition of plan knowledge by providing graphical representations of domain entities from the users' point of view. It will also allow users to replay the specification of plans and interactively debug this animated display.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"04 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129185037","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}
