1. Apparatus for translating textual information expressed in a source natural language into textual information expressed in a target natural language, comprising: a textual input interface for receiving and storing the textual information in the source natural language; a translation engine, comprising: a preparser for resolving ambiguities and determining the end of a sentence, comprising: means for dividing the input text into words, and means for associating the words with one or more dictionary entries and a sequence of words with one or more multiword dictionary entries, the means for associating including one or more dictionaries; a parser comprising a grammar rules data base for computing possible syntactic interpretations of a sentence by application of grammar rules to applicable sentence constituents, the syntactic possibilities being stored in a chart; a graph making engine for expanding the chart into a graph which includes semantic interpretations of the sentence, the graph comprising: one or more nodes, wherein one node is assigned to each different combined syntactic and semantic interpretation for a particular substring of the sentence, each node's information being generated from a subnode(s) from which the node was formed and the grammar rule which was used to form the node; and one or more pointers connecting a higher level node to its subnode, wherein a node without a subnode corresponds to a dictionary entry; a storage means accessible to the graph making engine for storing each node and its semantic and syntactic information; means for propagating the semantic information associated with each node upward through the graph; an expert evaluator comprising a plurality of experts for evaluating the graph of stored semantic, syntactic, and other information for each node, wherein each expert assigns a numerical weight (N) to the node; a scoring module for evaluating and combining the numerical weight (N) assigned each node by the experts, the scoring module storing the best combined numerical weight (N) scores for each node and also using the list of scores from the subnodes of the node to compute the node's score list; a parse extractor for creating a parse tree structure from any best numerical weight (N) represented on the list of such weights for each node; a structural converter having conversion tables for the target language for performing a structural conversion on the parse tree structure generated by the parse extractor to obtain a translation of the source language text to the target language, wherein the structural converter further includes components which control structural conversion based on access to one or more dictionaries or other data files; a display for displaying the translation to the user; a user interface permitting the user to interact with the translation engine to obtain alternative translations once the apparatus has provided the user with the best translation of the source language, the user interface allowing the user to request alternative translations for a word, the entire sentence, or any sequence of words in the sentence, and allowing the user to view retranslation of the entire sentence which includes the alternatives for the portion of the sentence that the user selected; and an editing interface module coupled to the display and responsive to the user input device and the storage means, including a graph access module responsive to input from the user input device to alter a decision by the scoring module and to display an alternate translation on the display.
