Grounding in communication
- In
, 1991
"... We give a general analysis of a class of pairs of positive self-adjoint operators A and B for which A + XB has a limit (in strong resolvent sense) as h-10 which is an operator A, # A! Recently, Klauder [4] has discussed the following example: Let A be the operator-(d2/A2) + x2 on L2(R, dx) and let ..."

B = 1 x 1-s. The eigenvectors and eigenvalues of A are, of course, well known to be the Hermite functions, H,(x), n = 0, l,... and E, = 2n + 1. Klauder then considers the eigenvectors of A + XB (A> 0) by manipulations with the ordinary differential equation (we consider the domain questions
The Structure and Performance of an Open-Domain Question Answering System
- In Proceedings of the Conference of the Association for Computational Linguistics (ACL-2000
, 2000
"... This paper presents the architecture, operation and results obtained with the LASSO Question Answering system developed in the Natural Language Processing Laboratory at SMU. To find answers, the system relies on a combination of syntactic and semantic techniques. The search for the answer is ..."

On the optimality of the simple Bayesian classifier under zero-one loss
- MACHINE LEARNING
, 1997
"... The simple Bayesian classifier is known to be optimal when attributes are independent given the class, but the question of whether other sufficient conditions for its optimality exist has so far not been explored. Empirical results showing that it performs surprisingly well in many domains containin ..."

Where are the ‘Killer Applications ’ of Restricted Domain Question Answering?
"... From a language technologist’s point of view, the penetration of natural language interfaces onto today’s web is somewhat disappointing; it seems that information retrieval, forms based, metaphor-based and hyper-link interfaces dominate all points of the design space. While open domain question answ ..."

Using Information Fusion for Open Domain Question Answering
, 2005
"... In open domain Question Answering, answer candidates are ranked according to individual features such as matching the answer type expected by the question. We report on a technique based on the fusion of candidate answers and their context into answer neighbourhoods to provide better features ..."

Type checking in open-domain question answering, in:
- Proceedings of the 16th European Conference on Artificial Intelligence (ECAI
, 2004
"... Abstract Many open domain question answering systems answer questions by first harvesting a large number of candidate answers, and then picking the most promising one from the list. One criterion for this answer selection is type checking: deciding whether the candidate answer is of the semantic ty ..."

Ecology of the family as a context for human development: Research perspectives.
- Developmental Psychology,
, 1986

This review collates and examines critically a theoretically convergent but widely dispersed body of research on the influence of external environments on the functioning of families as contexts of human development. Investigations falling within this expanding domain include studies of the interac ..."

Group formation in large social networks: membership, growth, and evolution
- IN KDD ’06: PROCEEDINGS OF THE 12TH ACM SIGKDD INTERNATIONAL CONFERENCE ON KNOWLEDGE DISCOVERY AND DATA MINING
, 2006
"... The processes by which communities come together, attract new members, and develop over time is a central research issue in the social sciences — political movements, professional organizations, and religious denominations all provide fundamental examples of such communities.

Implementing clarification dialogues in open domain question answering
- Journal of Natural Language Engineering

We examine the implementation of clarification dialogues, a mechanism for ensuring that question answering systems take into account user goals by allowing them to ask series of related questions either by refining or expanding on previous questions with follow-up questions, in the context of open d ..."

A speech interface for open-domain question-answering
- in Proc. ACL 2003
"... Speech interfaces to question-answering systems offer significant potential for finding information with phones and mobile networked devices. We describe a demonstration of spoken question answering using a commercial dictation engine whose language models we have customized to questions, a Web-base ..."
