Tactical Generation in a Free Constituent Order Language
This paper describes tactical generation in Turkish, a free constituent order
language, in which the order of the constituents may change according to the
information structure of the sentences to be generated. In the absence of any
information regarding the information structure of a sentence (i.e., topic,
focus, background, etc.), the constituents of the sentence obey a default
order, but the order is almost freely changeable, depending on the constraints
of the text flow or discourse. We have used a recursively structured finite
state machine for handling the changes in constituent order, implemented as a
right-linear grammar backbone. Our implementation environment is the GenKit
system, developed at Carnegie Mellon University--Center for Machine
Translation. Morphological realization has been implemented using an external
morphological analysis/generation component which performs concrete morpheme
selection and handles morphographemic processes.Comment: gzipped, uuencoded postscript fil

Survey of the State of the Art in Natural Language Generation: Core tasks, applications and evaluation
This paper surveys the current state of the art in Natural Language
Generation (NLG), defined as the task of generating text or speech from
non-linguistic input. A survey of NLG is timely in view of the changes that the
field has undergone over the past decade or so, especially in relation to new
(usually data-driven) methods, as well as new applications of NLG technology.
This survey therefore aims to (a) give an up-to-date synthesis of research on
the core tasks in NLG and the architectures adopted in which such tasks are
organised; (b) highlight a number of relatively recent research topics that
have arisen partly as a result of growing synergies between NLG and other areas
of artificial intelligence; (c) draw attention to the challenges in NLG
evaluation, relating them to similar challenges faced in other areas of Natural
Language Processing, with an emphasis on different evaluation methods and the
relationships between them.Comment: Published in Journal of AI Research (JAIR), volume 61, pp 75-170. 118

Exploring the episodic structure of algebra story problem solving
This paper analyzes the quantitative and situational structure of algebra story problems, uses these materials to propose an interpretive framework for written problem-solving protocols, and then presents an exploratory study of the episodic structure of algebra story problem solving in a sizable group of mathematically competent subjects. Analyses of written protocols compare the strategic, tactical, and conceptual content of solution attempts, looking within these attempts at the interplay between problem comprehension and solution. Comprehension and solution of algebra story problems are complimentary activities, giving rise to a succession of problem solving episodes. While direct algebraic problem solving is sometimes effective, results suggest that the algebraic formalism may be of little help in comprehending the quantitative constraints posed in a problem text. Instead, competent problem solvers often reason within the situational context presented by a story problem, using various forms of "model-based reasoning" to identify, pursue, and verify quantitative constraints required for solution. The paper concludes by discussing the implications of these findings for acquiring mathematical concepts (e.g., related linear functions) and for supporting their acquisition through instruction
Research on speech understanding and related areas at SRI
Research capabilities on speech understanding, speech recognition, and voice control are described. Research activities and the activities which involve text input rather than speech are discussed
Competing through business models
In this article a business model is defined as the firm choices on policies, assets and governance structure of those policies and assets, together with their consequences, be them flexible or rigid. We also provide a way to represent such business models to highlight the dynamic loops and to facilitate understanding interaction with other business models. Furthermore, we develop some tests to evaluate the goodness of a business model both in isolation as well as in interaction with other business models of different organizations, be those competitors, complements, suppliers, partners, etc.Business model; Interaction; Competitive Strategy; Competitive Dynamics;
