Don't Blame Distributional Semantics if it can't do Entailment
Distributional semantics has had enormous empirical success in Computational
Linguistics and Cognitive Science in modeling various semantic phenomena, such
as semantic similarity, and distributional models are widely used in
state-of-the-art Natural Language Processing systems. However, the theoretical
status of distributional semantics within a broader theory of language and
cognition is still unclear: What does distributional semantics model? Can it
be, on its own, a fully adequate model of the meanings of linguistic
expressions? The standard answer is that distributional semantics is not fully
adequate in this regard, because it falls short on some of the central aspects
of formal semantic approaches: truth conditions, entailment, reference, and
certain aspects of compositionality. We argue that this standard answer rests
on a misconception: These aspects do not belong in a theory of expression
meaning, they are instead aspects of speaker meaning, i.e., communicative
intentions in a particular context. In a slogan: words do not refer, speakers
do. Clearing this up enables us to argue that distributional semantics on its
own is an adequate model of expression meaning. Our proposal sheds light on the
role of distributional semantics in a broader theory of language and cognition,
its relationship to formal semantics, and its place in computational models.Comment: To appear in Proceedings of the 13th International Conference on

The pragmatics of specialized communication
El presente artículo pretende poner de manifiesto la importancia de la
pragmática en relación con la comunicación especializada. La estructura, el
contenido y la terminología de los textos especializados se ven afectados por
factores como la propia situación comunicativa y el conocimiento, intenciones,
expectativas y creencias previos del emisor del texto. La transmisión de tal
significado es difícil incluso en una sola lengua. Cuando la transmisión se
produce entre dos lenguas, como es el caso de cualquier acto de traducción, las
dificultades se multiplican. Por esta razón, es fundamental que los traductores
sean conscientes de cómo la pragmática, más que ningún otro componente del
lenguaje, puede afectar de forma decisiva a su actividad profesional
Generative grammar
Generative Grammar is the label of the most influential research program in linguistics and related fields in the second half of the 20. century. Initiated by a short book, Noam Chomsky's Syntactic Structures (1957), it became one of the driving forces among the disciplines jointly called the cognitive sciences. The term generative grammar refers to an explicit, formal characterization of the (largely implicit) knowledge determining the formal aspect of all kinds of language behavior. The program had a strong mentalist orientation right from the beginning, documented e.g. in a fundamental critique of Skinner's Verbal behavior (1957) by Chomsky (1959), arguing that behaviorist stimulus-response-theories could in no way account for the complexities of ordinary language use. The "Generative Enterprise", as the program was called in 1982, went through a number of stages, each of which was accompanied by discussions of specific problems and consequences within the narrower domain of linguistics as well as the wider range of related fields, such as ontogenetic development, psychology of language use, or biological evolution. Four stages of the Generative Enterprise can be marked off for expository purposes
Agents for educational games and simulations
This book consists mainly of revised papers that were presented at the Agents for Educational Games and Simulation (AEGS) workshop held on May 2, 2011, as part of the Autonomous Agents and MultiAgent Systems (AAMAS) conference in Taipei, Taiwan. The 12 full papers presented were carefully reviewed and selected from various submissions. The papers are organized topical sections on middleware applications, dialogues and learning, adaption and convergence, and agent applications
