In this paper we present an architecture for generating texts that vary in the emphasis put on conciseness, readability and the marking of particularly salient items. We abandon the traditional pipeline architecture, and use an integrated approach which makes the search for an optimum text explicit, taking into account both inter-sentential and intra-sentential features. We describe a context s...

Similarity-based generalization is fundamental to human cognition, and the ability to draw analogies based on relational similarities between superficially different domains is crucial for reasoning and inference. Learning to base generalization on shared relations rather than (or in the face of) shared perceptual features has been identified as an important developmental milestone. However, re...

Investigated is a number system in which the square of a basis number: (w), and the square of its additive inverse: (−w), are not equal. Termed W space, a vector space over the reals, this number system will be introduced by restating defining relations for complex space C, then changing a defining conjugacy relation from conj(z) + z = 0 in the complexes to conj(z) + z = 1 for W space. This cha...

It is shown that any context-sensitive language can be generated by a tree controlled grammar whose control language is accepted by a deterministic finite automaton with at most 5 states.

A stemming algorithm, a procedure to reduce all words with the same stem to a common form, is useful in many areas of computational linguistics and information-retrieval work. While the form of the algorithm varies with its application, certain linguistic problems are common to any stemming procedure. As a basis for evaluation of previous attempts to deal with these problems, this paper first d...

Freezing is a powerful technique for orienting equations. Here we give a new presentation of it which is suitable for an eecient automatic use. Further, it is shown how slight modiications of it can be applied to context-sensitive and innermost term rewriting. The experimental results on an extensive test series of non-trivial examples performed using a prototype implementation strongly underli...

Interactive narrative systems produce branching story experiences for a human user using an interactive world. A class of interactive narrative systems, called strong story systems, manage a user’s experience by manipulating the interactive world and its characters according to a formal story model. In these systems, a human user may place the world into a state such that the formal story model...

In this paper we present state-of-the-art results on the computational classification of semantic type coercion, accomplished using a novel geometric method which is both context-sensitive and generalisable. We show that this method improves accuracy on a SemEval dataset over previous work, and gives promising results on a new more challenging experimental setup involving the same data. In addi...

We describe how context-sensitive, usertailored output is specified and produced in the COMIC multimodal dialogue system. At the conference, we will demonstrate the user-adapted features of the dialogue manager and text planner.

A word-by-word human sentence processing complexity metric is presented. This metric formalizes the intuition that comprehenders have more trouble on words contributing larger amounts of information about the syntactic structure of the sentence as a whole. The formalization is in terms of the conditional entropy of grammatical continuations, given the words that have been heard so far. To calcu...
