    <Paragraph position="0"> The evalnator described in the paper is presently running in a prototype version (with about 50 rules and a small encyclopedia of about 40 frames) written in LISP on a SUN-2 workstation. It has been extensively tested on selected cases (extracted from textbcx)ks on operating systems), and it includes a preliminary implementation of the goal interpreter based on a simplified version of the referential knowledge base. Research work devoted to extend and refine this first version of the goal interpreter and to test its performance is now ongoing., Several open problems and challenging tOlfiCS will be the subject of future research. Among these we mention: - extending the goal representation kmgnage; - merging the encyclopedia and the referential knowledge base into a unified structure that encompasses all knowledge awtilable on the subject domain and can make it available in an effective way to the relevant modules of the ewduator (Sowa, 1984); - considering goals Ihat can change during text noderstauding, taking into account the topic-tbcus articulation of discotR'se - (Hajic.ova' and Sgall, 1984); - developing an explaa tion module that can justify the reasons behind the ovatua|iol\[IS l)rothlccd by the syst(:nl.</Paragraph>
