Textbook in PDF format This book contains the reports of selected projects involving natural language communication with pictorial information systems. More than just a record of research results, however, it presents concrete applications to the solution of a wide variety of problems. The authors are all prominent figures in the field whose authoritative contributions help ensure its continued expansion in both size and significance. Y. C. Lee and K S. Fu (Purdue University, USA) survey picture query languages which form an interface between the pictorial database system and the user and support information retrieval, data entry and manipulation, data analysis and output generation. They include explicit picture query languages that augment alphanumeric data query languages as well as languages and command sets which are implicitly embedded in a pictorial information system but perform similar functions. It is worth mentioning that some forms of query languages can be transformed from a given set of natural language sentences by using ATN (Augmented Transition Networks), which consequently allows for natural language communication with information system. M. Hussmann and P. Schefe (Hamburg University, West Germany) describe a natural language dialogue system for scene analysis: SWYSS (Say What You See System). Recently, SWYSS has been constrained to include several modules that can serve as an interface to a scene analysis system, the output of which is a geometric scene description. In this system, a phrase-structure grammar is used, augmented by dependency rules to produce dependency structures for natural language inputs not constrained to complete and well-formed sentences. M. Yokota, R Taniguchi and E. Kawaguchi (Kyushu University, Japan), in their paper "Language-Picture Question-Answering Through Common Semantic Representation and Its Application to the World of Weather Report", present methodologies for constructing systems which can understand both natural languages and pictorial patterns. These methodologies involve preliminary analysis of linguistic and pictorial data performed by corresponding pictorial data to linguistic from the viewpoints of syntax and semantics. Their understanding system consists of six divisions, all of which are connected through the medium of meaning representation common to language and picture. They also describe the applications of the understanding systems to weather reporting in a system called ISOBAR (an Information understanding System ofBasic weather Report). The most prominent feature of SOBAR is that its performance is based on the semantic processing of the input. O. Eriksson, E. Bengtsson, T. Jarkrans, B. Nordin and B. Stenkvist (Uppsala University, Sweden) introduce ILIAD, a comprehensive digital picture analysis system interacting with the user through a high level language. ILIAD runs on a general-purpose computer, but contains provisions for utilizing different kinds of special hardware. ILIAD's high levellanguage makes it programmable at the monitor level. Thus, different picture processing algorithms can be programmed directly using a PASCAL-like command language. The system is equipped with a procedure facility: a self-contained piece of ILIAD code which enables each picture processing problem to be expressed in a structured, thus simplifying the use of the system. The full system can be implemented by an experienced user, although for novices it could be simpler to use the preprogrammed procedures. We present this publication with the conviction that the problem it includes will help disseminate the knowledge generated by research in the field of natural language communication with pictorial information systems, an area still too little known in the world today.
