In this paper we demonstrate that there is a strong correlation between the Question Answering (QA) accuracy and the log-likelihood of the answer typing component of our statistical QA model. We exploit this observation in a clustering algorithm which optimizes QA accuracy by maximizing the log-likelihood of a set of question-and-answer pairs. Experimental results show that we achieve better QA...
In this demonstration, we present a multi-source hybrid Question Answering (QA) system. Our system consists of four sub-systems. 1) a knowledge base based QA, 2) an information retrieval based QA, 3) a keyword QA and 4) an information-extraction to construct our own knowledge base from web texts. With these sub-systems, we can query three types of information sources: curated knowledge bases, a...
n QA is a process of meeting quality standards and assuring that care reaches an acceptable level. Nursing homes typically set QA thresholds to comply with regulations. They may also create standards that go beyond regulations. QA is a reactive, retrospective effort to examine why a facility failed to meet certain standards. QA activities do improve quality, but efforts frequently end once the ...
Previous works on evaluating the performance of Question Answering (QA) systems are focused in the evaluation of the precision. Nevertheless, the importance of the answer time never has been evaluated. In this paper, we developed a mathematic procedure in order to explore new evaluation measures in QA systems considering the answer time. Also, we carried out an exercise for the evaluation of QA...
As we replied above, the aerosol mass absorption efficiency (Qa) is also estimated from PM10 measurements (see Line 5-6, Page 7 of Section. 3.3). We also will clarify this in the revised manuscript. Many previous studies also showed Qa for BC from lab-generated aerosols, ambient aerosols, diesel engines and theoretical calculations (e.g., Mie scattering theory). Bond and Bergstrom (2006) review...
Flows (Qa) of arteriovenous fistula (AVF) impact the dialysis adequacy in hemodialysis (HD) patients. However, data for different access flow levels on outcomes related to long-term dialysis patients, especially in Chinese patients, are limited. Herein, we performed an ambispective, mono-centric cohort study investigating the association between the AVF flows and inflammation, cardiovascular ev...
The German question answering (QA) system InSicht participated in QA@CLEF for the third time. InSicht realizes a deep QA approach: it builds on full sentence parses, inferences on semantic representations, and matching between semantic representations derived from questions and document sentences. InSicht was improved for QA@CLEF 2006 in the following main areas: temporal expressions are better...
In this paper, we discuss how to utilize the co-occurrence of answers in building an automatic question answering system that answers a series of questions on a specific topic in a batch mode. Experiments show that the answers to the many of the questions in the series usually have a high degree of co-occurrence in relevant document passages. This feature sometimes can’t be easily utilized in a...
