Twitter Based Sentiment Analysis of Each Presidential Candidate Using Long Sh...CSCJournals
In the era of technology and internet, people use online social media services like Twitter, Instagram, Facebook, Reddit, etc. to express their emotions. The idea behind this paper is to understand people’s emotion on Twitter and their opinion towards Presidential Election 2020. We collected 1.2 million tweets in total with keyword like “RealDonaldTrump”, “JoeBiden”, “Election2020” and other election related keywords using Twitter API and then processed them with natural language processing toolkit. A Bidirectional Long Short-Term Memory (BiLSTM) model has been trained and we have achieved 93.45% accuracy on our test dataset. We then used our trained model to perform sentiment analysis on the rest of our dataset. With the sentiment analysis results and comparison with 2016 Presidential Election, we have made predictions on who could win the US Presidential Election in 2020 with pre-election twitter data. We have also analyzed the impact of COVID-19 on people’s sentiment about the election.
Unsupervised Word Usage Similarity in Social Media TextsSpandana Gella
The document presents a methodology for modeling word usage similarity (Usim) in social media texts without supervision. It uses Latent Dirichlet Allocation (LDA) topic modeling to represent tweets containing target words as topic distribution vectors and evaluate models on a dataset of manually annotated Usim scores. LDA outperforms a baseline and benchmark, and expanding documents with hashtags improves performance. The study concludes LDA is suitable for modeling Usim in tweets.
The document discusses methods for collecting data through surveys, including interviews and questionnaires. It identifies two types of data - primary, which is collected by the researcher, and secondary, which comes from other studies. Examples are given to distinguish between primary and secondary data sources. The document also covers open-ended and closed-ended questions, and provides examples of different types of closed-ended questions like information, checklist, and ranking questions.
06 Network Study Design: Ethical Considerations and Safeguardsdnac
This document outlines ethical considerations and safeguards for social network study design. It discusses principles from the Belmont Report including respect for persons, beneficence, and justice. Key risks in social network research are deductive disclosure, outing people, and legal or privacy risks from relational data. Mitigation strategies include data agreements, restricting access to identifying data, training researchers, and communicating clearly with IRBs. The document emphasizes that social network studies require safeguarding participant and alter privacy.
Trust and Recommender System
This document discusses recommender systems and how trust models can be incorporated. It begins by outlining recommender systems and their applications. It then describes three trust models - MoleTrust, TidalTrust, and PageRank - and how they propagate trust through networks. The document concludes that introducing trust is effective in addressing issues with recommender systems like data sparsity and attacks by malicious users. Trust propagation must balance accuracy and coverage of recommendations.
This document describes a system created by researchers to analyze sentiment in tweets about 2012 US presidential candidates in real-time. The system collects tweets through the Twitter API, preprocesses them by tokenizing text, matches tweets to candidates, analyzes sentiment using a model trained on Twitter language, aggregates sentiment results by candidate, and visualizes the analysis through interactive dashboards. It provides up-to-the-minute insight into how public opinion responds to political events as expressed on Twitter.

The document discusses two types of voting advice systems: the Lipschits method from 1977-1998 and the Stemwijzer method on the web from 1998. It presents a demo of "Lipschits on the web" called VerkiezingsKijker, which allows direct access to party manifestos. The main challenge is bridging the semantic gap between user search terms and manifesto language; the system addresses this using hierarchical controlled vocabularies and document expansion techniques like term harvesting. The conclusion discusses making both systems complementary and continuing to standardize controlled vocabularies and data.
The document discusses the work of Joe McCarthy in hybrid computing, which mediates connections between people, places and things both online and offline. It summarizes three of McCarthy's projects that aimed to promote community: MusicFX helped democratize music selection at gyms, Proactive Displays enhanced connections at conferences, and C3 Collage increased sharing and relationships in workplaces. The document concludes by outlining some open challenges in hybrid computing regarding privacy, evaluation of systems in real-world settings, and mechanisms for situated serendipity.

Modeling Social Data, Lecture 2: Introduction to Countingjakehofman
The document is a lecture on counting and modeling social data given by Jake Hofman at Columbia University on January 27, 2017. It discusses why counting large datasets is important for social science questions but computationally challenging at large scales. It also covers counting at small to medium scales by loading a dataset into memory and splitting it into groups to compute statistics within each group.
In order to explore public attitudes towards the use of data from online services (e.g. social media) or digital devices (e.g. mobile phone GPS), we are running a Twitter based campaign (#AnalyzeMyData) in which we reminded people of instances of data usage that have been reported in news stories and asked them to rate if they considered these data uses to be OK. In order to produce momentum of public participation we designed the experiment as a sustained campaign in which a different news item is presented each day over a period of multiple weeks. Each Tweet includes a link to a mini-survey which asks participants to respond, 'yes', 'no' or 'depends'. To further motivate continued participation as the campaign progresses, we provide a running update on our website of the response statistics to the items that were previously Tweeted. The types of data usage included in the campaign range from academic studies of social media use, to data collection for product development, marketing and government studies. Our hope is that this campaign/experiment will 1) help to raise awareness of the various ways in which personal data, acquired through online services of digital devices, is currently being used, and 2) provide a large dataset of case-studies with an associated baseline of public acceptance/rejection that can be used for future research ethics guidelines and review training.
This document covers lessons on civic responsibility, including the electoral process, the two-party system, public opinion, media, interest groups, lobbyists, and responsible government. It discusses key aspects of each topic like the characteristics of a good candidate, the electoral college process, the effects and organization of the two-party system, how public opinion is formed and its characteristics, how interest groups and lobbyists try to influence legislation, and the role of political parties in creating a stable government.

Text Messaging Field Experiment (RootsCampDC 12/06)rootscamp
1) The study aimed to test whether text message reminders could increase voter turnout among young people by conducting randomized experiments and surveys with over 12,000 newly registered voters.
2) Cell phone numbers were collected voluntarily from progressive student and online organizations. The numbers were verified to eliminate landlines.
3) Preliminary survey results found that while a minority had negative reactions to the texts, the majority had positive or neutral reactions. Receiving the text did not deter people from voting. Young people preferred text and email as contact methods.
The document provides an overview of marketing research, outlining the four key steps in the marketing research process: 1) defining the problem and research objectives, 2) developing the research plan, 3) implementing the research plan by collecting and analyzing data, and 4) interpreting and reporting findings. It discusses different types of research objectives and approaches, and how to choose appropriate data collection methods and samples. The goal of marketing research is to provide an essential link between the market and marketing manager by bringing the voice of the customer.
This document provides guidelines for journalists on appropriately reporting opinion polls. It discusses [1] determining whether a poll meets professional standards, [2] deciding if a poll's findings have newsworthiness, and [3] the appropriate way to publish poll findings. Key points include checking a poll's methodology, sample size, and margin of error; using polls to enhance issues coverage rather than set the agenda; and providing full context and disclosure when publishing poll results. The guidelines aim to help journalists identify valid, reliable polls and determine the most meaningful way to communicate poll findings to their audience.
This document discusses the civic responsibilities of voting and participation in the electoral process. It covers the characteristics of a good political candidate and the steps to run for president, including announcing candidacy, participating in primaries and conventions, and the general election and electoral college process. It also summarizes the two-party system in the US and how third parties can still win local and state elections. Additional topics covered include public opinion, the role of media, interest groups that advocate for shared interests, the role of lobbyists in influencing legislation, and how political parties and parliamentary systems can promote responsible government.
This is the third class in a course on Org. Communication in Social Context; in it I pull together the need for business strategy and communication strategy to be aligned. And, I criticize stakeholder theory as too limiting.
Research is an important step in preparing an advocacy campaign. Careful, objective research educates supporters about causes and effects of problems. The document discusses various research methods like surveys, interviews, focus groups, and secondary data collection. It also covers topics like sampling, designing survey questions, analyzing qualitative and quantitative data, and presenting research findings to different audiences.
1. The document outlines the six main stages of the marketing research process: defining the problem, developing an approach, formulating a research design, collecting data, analyzing data, and preparing and presenting the report.
2. It discusses various methods for collecting primary and secondary data, including surveys, experiments, observation, and qualitative research techniques.
3. It also covers important considerations for marketing research such as questionnaire design, sampling, and ensuring samples are representative of the target population.
This document summarizes a speech given by Gary Langer at the American Association for Public Opinion Research conference in Orlando, Florida on May 18, 2012. In the speech, Langer defends the use of probability sampling for survey research. He discusses how probability sampling allows researchers to make reliable estimates about population values and trends over time. Langer expresses skepticism about non-probability online panels and their ability to produce representative data. He argues that all survey methods, both new and established, should be rigorously evaluated and that fitness for purpose should be considered.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

The Potential and Perils of Election Prediction Using Social Media Sources
1. The Potential and Perils of
Election Prediction Using
Social Media Sources
Federico Nanni and Josh Cowls
University of
Mannheim/Comparative Media
Studies, MIT
2. Reasons to be cheerful
+ Social media data is (often) cheap
+ Phone response rates are in decline
+ More granularity available?
Cost
Utility
Traditional inferential model Social media model
3. Reasons to be doubtful
- Myriad reliability issues...
– Difficult to establish the meaning
of latent messages
– Platform specific behaviours (e.g.
hashtags, likes) are not always
understood
– Political discourse often laced
with e.g. sarcasm
- The ethics of collecting and
using social media data
4. Results to date have been mixed...
• A meta-analysis found little evidence that
using Twitter to predict elections is better
than chance in the aggregate (Gayo-Avello,
2013)
• Nonetheless, social media can provide an
‘early warning system’ for a candidate’s
momentum (Jensen and Anstead, 2013)
• Big problem: what’s in a name?
5. Our approach:
intention over attention
• Most models count references to candidates’
or parties’ names – measuring attention
• Other models use sentiment analysis,
seeking to ascertain emotion responses to
candidates
• We built an intention model, collecting
instances of vote declarations for specific
candidates
6. Case study
• Context: Labour and the Lib Dems
required new leaders in 2015 (after a
polling fail!)
• Leadership elections conducted in summer
2015
– Lib Dems: two candidates (Tim Farron,
Norman Lamb)
– Labour: four candidates (Jeremy Corbyn,
Andy Burnham, Yvette Cooper, Liz Kendall)
7. Advantages of our case
• Primary candidates’ names easier to isolate
than ambiguous party names (“Labour”,
“Liberal”)
• Party elections are a minority sport – better
signal to noise ratio?
• Start and end dates clear; postal vote system
ensured greater period of decision-making
8. Method
Wrote Python scripts to collect tweets which:
Mentioned the name of a candidate
Included a specific declaration to vote (“I’ll vote for...”,
“I’m voting for” etc)
Cleaned data
Removed non-declarations (“I’m not voting for...”)
Ascertained preferred candidate in ambiguous cases
Final dataset: 1361 valid declarations for Lib Dem
race and 17617 for Labour
11. Key successes
• ‘Intention’ model beat out ‘Attention’ model
in 5 out of 6 races, and in both races
overall
• Lib Dem prediction accuracy close to
traditional margin of error (MOE = 3.5)
• Caught Corbyn’s success to a high degree
