Introduction

• Query Routing (QR) is the process of directing questions to appropriate responders

– Community Question and Answering Services (CQA)

– Online Social Networks (OSN)

• We are proposing an Expertise Finding System to automatically routing questions on Social Networks

Cleyton Souza - ICIW 2013 2

Introduction

• Our goal is to present the Social Query System • How does it work?

• How does the usual Q&A process is affected?

• Talk about our preliminary results

• Talk about our planning for the future


Agenda

• Introduction

• Related Work & Background

• Usual Q&A

• Social Query System: How it works

• Evaluation & Results

• Future Work


Related Work & Background

• The differential of our research

– We are proposing a Query Routing to an OSN context

• Previous work usually focused on CQA context

• We are proposing a solution to a pre-existent and popular context: Twitter

• Most part of questions asked on Twitter are not answered (more than 80%) [Paul et al. 2012]

– We lead with the recommendation as multi-criteria decision making problem

• Previous work usually apply probabilistic or Information Retrieval-based models;


Usual Q&A on OSN

• Sharing a public question

Q&A on OSN

• Directing the question

Q&A on OSN

• Routing the question

Social Query System

• Works outside Twitter

– Questioner’s Followers are Expert Candidates

– Questions and Answers without size limitations

“New Question” Page

• Three text fields, two mandatory

“Recommendation List” Page

• Questioner chooses who will “receive” the question

Question’s Tweet

• Questioner tweets the following message

“New Answer” Page

• Three options of answer

“I don’t Know” & “I know Someone”

I want answer

• When the expert clicks on the “I want answer” button

Tweeting about the Answer

How does it work?

• (1) The questioner accesses our System and (2) informs his question;

• (3) The System recommends potential responders and (4) the questioner chooses to whom direct the question;

• (5) Those chosen access our System, (6) answers the question, (7) and informs the questioner about his answer;

• (8) The questioner access our System, (9) see the answer, and (10) evaluates it.


Evaluation

• Nine Volunteers evaluated ten recommendations for a couple of questions

a) Looking for a new band to listen during weekend, does anyone have an indication?

b) Going to the movie theater after years LOL. What is the best movie in theaters?

• Each recommendation was labeled as good (relevance 1), neutral (relevance 0) and bad (relevance 0).

• These labels reflect the opinion of the volunteers about the recommendation

Future Work

• Where are we?

• Mobile App

• Volunteer’s feedback

– Follow Back Filter

– Thesaurus

• Real case study
