ADAPT Centre for Digital Content Technology analyse Irish General Election activity

16 Feb 2016


Researchers at the ADAPT Centre for Digital Content Technology are working with RTE to monitor and analyse activity on Twitter related to the 2016 Irish General Election. The system that has been developed within ADAPT can quickly track the volume of tweets and gauge reaction and sentiment from the tweets in relation to election topics, parties and candidates. The project presents a graphical analysis of tweets that can be filtered by party or candidate allowing the user quickly understand and gain insights into the conversations on election topics taking place on Twitter.

The research team developed a system that harvests and filters tweets using the main party hashtags, candidate twitter handles, names, and expected election topics along with associated keywords and synonyms. This information is then presented in a series of graphs highlighting top issues, candidate mentions, party mentions, and sentiment to government and opposition parties. Tweets can be filtered by date, party and candidate in any combination.

The lead Principal Investigator on the project was Professor Séamus Lawless from the ADAPT Centre at Trinity College Dublin’s School of Computer Science and Statistics. Professor Lawless led a team consisting of Motasim Alsayed, Haithem Afli, and Matthew Nicholson.

ADAPT research addresses industry problems and real-world challenges as well as progressing the state-of-the-art in digital content technology. Professor Séamus Lawless heads up Social Media Analysis within ADAPT. This area involves the analysis of content and relationships in social media platforms, analysing populations of users who are engaged in conversations both with each other and with the enterprise. This area focuses on the detection and tracking of user behaviour that may represent opportunities for, or risks to, the enterprise and other users.

Sentiment Analysis

The ADAPT developed ‘SentiWordsTweet’ tool enables automatic sentiment classification of Tweets using opinion lexicons that associate sentiment polarity for words. Sentiment is scored positive, negative or objective. Using opinion lexicons in opinion mining research stems from the hypothesis that individual words can be considered as a unit of opinion information. The word is them classed positive if it has more entries where the positive score is greater than negative score; negative if it has more entries where the negative score is greater than the positive score; and neutral when there is no variation between positive and negative. To ensure the scoring was accurate, new strong positive and negative lexicons were extracted from 40,000 tweets related to the Election in Ireland along with a new technique for scoring using an exponential weighting of the tweet words.

ADAPT is a Science Foundation Ireland funded research centre focusing on digital content technology. The centre is hosted by Trinity College Dublin’s School of Computer Science and Statistics and combines the world-class expertise of researchers at Dublin City University, University College Dublin and Dublin Institute of Technology.
