The Viewpoints FAQ
The structure of this brief paper follows an emerging convention the FAQ Frequently Asked Questions list. FAQs have grown out of Internet newgroups where participants, tired of seeing the same questions repeated by newcomers, provide a list of canned answers to the most frequently asked questions. An FAQ also provides a covert role in defusing tiresome or unduly acrimonious debates by summarisi...
متن کاملDCU@FIRE2012: Monolingual and Crosslingual SMS-based FAQ Retrieval
This paper presents results for DCU’s second participation in the SMS-based FAQ Retrieval task at FIRE. For FIRE 2012, we submitted runs for the monolingual English and Hindi and the crosslingual English to Hindi subtasks. Compared to our experiments for FIRE 2011, our system was simplified by using a single retrieval engine (instead of three) and using a single approach for detecting out-of-do...
متن کاملWeb-Based Communication Strategies Designed to Improve Intention to Minimize Risk for Colorectal Cancer: Randomized Controlled Trial
BACKGROUND People seek information on the Web for managing their colorectal cancer (CRC) risk but retrieve much personally irrelevant material. Targeting information pertinent to this cohort via a frequently asked question (FAQ) format could improve outcomes. OBJECTIVE We identified and prioritized colorectal cancer information for men and women aged 35 to 74 years (study 1) and built a websi...
متن کاملFAQ Mining Via List Detection
This paper presents an approach to FAQ mining via a list detection algorithm. List detection is very important for data collection since list has been widely used for representing data and information on the Web. By analyzing the rendering of FAQs on the Web, we found a fact that all FAQs are always fully/partially represented in a list-like form. There are two ways to author a list on the Web....
متن کاملRecent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells
Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes have shown significant properties such...
