Here follows the current list of publicly available publications for download (in PDF format).
You may also download the corresponding BiBTeX entries. Note that most publishers only allow
journal or conference papers to be placed on a personal web page after a certain grace period,
hence the coming soon message you may encounter. I have also a few other papers on
the pipeline, and eventually they will find their way into this page.
An Integrated Framework for Supporting Photo Retrieval Activities in Home Environments
Dario Teixeira, Wim Verhaegh and Miguel Ferreira
This paper addresses the content overload problem applied to photo
retrieval activities in the home environment. The starting point is
an analysis of the main activities that users perform with their
photographs. We then discuss two different interaction paradigms,
namely browsing assistants and conversational search, which can
provide software assistance to help users cope with increasing
numbers of photographs. The major contribution is the presentation
of an integrated architecture which combines these interaction
paradigms to provide the user with a home-friendly, multimodal,
and seamless system for photo viewing. We also discuss the user
interaction aspects, internal architecture, and algorithms of each
of the two paradigms.

Optimising Attribute Selection in Conversational Search
Dario Teixeira and Wim Verhaegh
It has been shown that user modelling has the potential to
improve the performance of conversational search systems,
particularly in what concerns the problem of attribute
selection, i.e., determining which attribute to ask
the user at each step of the dialogue. In this paper we
present a novel framework for attribute selection which
allows the fine-tuning of the relative importance of
profile-based and entropy-based heuristics. Based on this
framework, we describe a number of experiments which allow
us to quantify the bounds to such improvements.

In-Home Access to Multimedia Content
Dario Teixeira and Yassine Faihe
This paper discusses the problem of content overload in the home environment.
We describe the various domains where the problem manifests itself, and we
analyse which user activities could benefit from software assistance.
In particular, we focus on the problem of searching for information, and we
introduce the concept of Conversational Search as the means to
tackle it. We also introduce a framework to test several heuristics related
to Conversational Search, and show how using a model of the user can
significantly improve the results of purely information-theoretical heuristics.
