Pangloss implements “Optimistic Visualization”, a method that gives analysts confidence to use approximate results for exploratory data analysis. In this position paper, we outline some ways in which user experiences with an approximate visualization system did not match analysts’ intuitions. These observations have implications for the design of future systems that expose uncertainty to users.

of an integrated knowledge-based machine-aided translation system called PANQLOSS. The ISI-specific work includes the development of English sentence generation and sentence planning capabilities and the construction of an Ontology of concepts to act as the semantic lexicon for all modules of the system as a whole. In addition, we continue to enhance Penman's existing generation technology, to ...

Since MT systems, whatever translation method they employ, do not reach an optimum output on free text; each method handles some problems better than others. The PANGLOSS Mark III system is an MT environment that uses the best results from a variety of independent MT systems or engines working simultaneously within a single framework on the same text. This paper describes the method used to com...

over, and what kinds of symbol systems should we create for them? Everytime a new phenomenon is identified as a bottleneck or as problematic, the very actsof describing the phenomenon, defining it,and creating a set of symbols to represent its abstractions are symbolic (in both senses of the word!). The benefits: decreasedlearning time and more powerful rules,hence improved ...

The project involves three sites (NMSU, USC, CMU) and is devoted to enhancing the state of the art in machine translation of natm'al language texts. Pangloss uses a hybrid, multi-engine approach, though knowledge-based machine translation takes a majority of resources. Types of work in the knowledge-based direction include: • continuing development of a set of knowledge acquisition tools and ut...

A comprehensive review about machine translation and ontologies is meant to investigate both the topic of ontologies for MT and MT for ontologies. The former identifies a research area (’80s-’90s) dealing with interlingual knowledge-based MT systems. A general background is presented, together with two case studies, namely PANGLOSS and Mikrokosmos. The latter is a topic appeared recently with r...

The concept of specification architecture is introduced, and its importance is emphasised. Three important architectural principles are offered as a way of achieving a satisfactory specification architecture: modularity, generality and simplicity. These are supported by subsidiary techniques that realise them. Criteria are identified to evaluate successful application of the techniques and conf...

The Pangloss Example-Based Machine Translation engine (I 'anEI3MT) l is a translation system reql,iring essentially no knowledge of the structure of a language, merely a large parallel corpus of example sentences atn[ a bilingual dictionary. Input texts are segmented into sequences of words occurring in the corpus, for which translations are determined by subsententia[ alignment of the sentence...
