This book constitutes the proceedings of the First International Conference on User Modeling, Adaptation, and Personalization, held in Trento, Italy, on June 22-26, 2009.

This annual conference was merged from the biennial conference series User Modeling, UM, and the conference on Adaptive Hypermedia and Adaptive Web-Based Systems, AH.

The 53 papers presented together with 3 invited talks were carefully reviewed and selected from 125 submissions. The tutorials and workshops were organized in topical sections on constraint-based tutoring systems; new paradigms for adaptive interaction; adaption and personalization for Web 2.0; lifelong user modeling; personalization in mobile and pervasive computing; ubiquitous user modeling; user-centered design and evaluation of adaptive systems.

In recent years the idea that an adequate semantics of ordinary language calls for some theory of events has sparked considerable debate among linguists and philosophers. Speaking of Events offers a vivid and up-to-date indication of this debate, with emphasis precisely on the interplay between linguistic applications and philosophical implications. Each chapter has been written expressly for this volume by leading authors in the field, including Nicholas Asher, Pier Marco Bertinetto, Johannes Brandl, Denis Delfitto, Regine Eckardt, James Higginbotham, Alessandro Lenci, Terence Parsons, Alice ter Meulen, and Henk Verkuyl.

The view that an adequate semantics of natural language calls for some theory of events has been a focus of considerable debate among linguists and philosophers. This book offers a vivid and

up-to-date indication of this debate, with contributions by leading experts. A comprehensive introductory essay is included.

This book examines the interactions between the morphosyntax and the semantic interpretation of tense and aspectual forms in the Germanic and Romance languages. These languages diverge not only in their variety of tense and aspectual forms, but also in the distribution and interpretation of given forms. Adopting Noam Chomsky's minimalist framework, AG and FP attempt to provide theoretical explanations for the observed patterns of form and meaning which link the morphosyntactic properties of languages in both universal and language-particular constraints on interpretation.

The authors bridge the gap between the semantic and syntactic properties of verb tense and aspect, and suggest a unified account of tense and aspect using Chomsky's Principles and Parameters Framework. They compare tense and aspect systems in Romance languages with Germanic ones.
