First Claim
1. In a variety of systems for information retrieval where natural language is inputted by inputting means, a user interface system for information retrieval, comprising:
- means for sequentially effecting syntactic and semantic analysis, every time a retrieval request sentence is inputted, on words and clauses of said retrieval request sentence;
means for creating partial syntactical and semantic expressions from successively obtained results of said syntactic and semantic analysis;
means for predicting words or clauses which are to be next inputted as said retrieval request sentence by making use of a semantic relation between a syntactic and semantic expression and an associated task;
means for displaying candidates for said predicted words or clauses; and
means for taking in selected words or clauses as subsequent words or clauses of said retrieval request sentence and permitting a user to select at least one of said displayed candidates.

Abstract
A user interface system for information retrieval which includes apparatus for sequentially effecting syntactic and semantic analysis, every time a retrieval request sentence is inputted on words and clauses of the request sentence, apparatus inputted for creating partial syntactic and semantic expressions from successively obtained results of the syntactic and semantic analysis, apparatus for predicting words or clauses which are to be next inputted as the retrieval request sentence by making use of a semantic relation between the syntactic and semantic expression and an associated task, apparatus for displaying candidates for the predicted clauses, and apparatus for taking in selected clauses as subsequent clauses of the retrieval request sentence by and permitting a user to select at least one of the displayed candidates.
