Special Track on Artificial Intelligence for Big Social Data Analysis
Bell, Eric (Pacific Northwest National Laboratory) | Patti, Viviana (University of Turin)
This track includes data-related tasks such as analysis, capture, curation, search, sharing, storage, transfer, visualization, and information privacy, with special focus on social data on the web. Hence, the broader context of the track comprehends AI, web mining, information retrieval, natural language processing, and sentiment analysis. As the web rapidly evolves, web users are evolving with it. In an era of social connectedness, people are becoming increasingly enthusiastic about interacting, sharing, and collaborating through social networks, online communities, blogs, wikis, and other online collaborative media. In recent years, this collective intelligence has spread to many different areas, with particular focus on fields related to everyday life such as commerce, tourism, education, and health, causing the size of the social web to expand exponentially. The distillation of knowledge from such a large amount of unstructured information, however, is an extremely difficult task, as the contents of today’s web are perfectly suitable for human consumption, but remain hardly accessible to machines. The opportunity to capture the opinions of the general public about social events, political movements, company strategies, marketing campaigns, and product preferences has raised growing interest both within the scientific community, leading to many exciting open challenges, as well as in the business world, due to the remarkable benefits to be had from marketing and financial market prediction. The primary aim of this track is exploring the new frontiers of big data computing for opinion mining and sentiment analysis through machine learning techniques, knowledge-based systems, adaptive and transfer learning, in order to more efficiently retrieve and extract social information from the web.
Neural User Simulation for Corpus-based Policy Optimisation for Spoken Dialogue Systems
Kreyssig, Florian, Casanueva, Inigo, Budzianowski, Pawel, Gasic, Milica
User Simulators are one of the major tools that enable offline training of task-oriented dialogue systems. For this task the Agenda-Based User Simulator (ABUS) is often used. The ABUS is based on hand-crafted rules and its output is in semantic form. Issues arise from both properties such as limited diversity and the inability to interface a text-level belief tracker. This paper introduces the Neural User Simulator (NUS) whose behaviour is learned from a corpus and which generates natural language, hence needing a less labelled dataset than simulators generating a semantic output. In comparison to much of the past work on this topic, which evaluates user simulators on corpus-based metrics, we use the NUS to train the policy of a reinforcement learning based Spoken Dialogue System. The NUS is compared to the ABUS by evaluating the policies that were trained using the simulators. Cross-model evaluation is performed i.e. training on one simulator and testing on the other. Furthermore, the trained policies are tested on real users. In both evaluation tasks the NUS outperformed the ABUS.
Location-Based Twitter Sentiment Analysis for Predicting the U.S. 2016 Presidential Election
Heredia, Brian (Florida Atlantic University) | Prusa, Joseph D. (Florida Atlantic University) | Khoshgoftaar, Taghi M. (Florida Atlantic University)
We seek to determine the effectiveness of using location-based social media to predict the outcome of the 2016 presidential election. To this aim, we create a dataset consisting of approximately 3 million tweets ranging from September 22nd to November 8th related to either Donald Trump or Hillary Clinton. Twenty-one states are chosen, with eleven categorized as swing states, five as Clinton favored and five as Trump favored. We incorporate two metrics in polling voter opinion for election outcomes: tweet volume and positive sentiment. Our data is labeled via a convolutional neural network trained on the sentiment140 dataset. To determine whether Twitter is an indicator of election outcome, we compare our results to the election outcome per state and across the nation. We use two approaches for determining state victories: winner-take-all and shared elector count. Our results show tweet sentiment mirrors the close races in the swing states; however, the differences in distribution of positive sentiment and volume between Clinton and Trump are not significant using our approach. Thus, we conclude neither sentiment nor volume is an accurate predictor of election results using our collection of data and labeling process.
Improving Topic Model Visualization via Multi-Dimensional Scaling and Cliques
Lin, King Ip (David) (Baylor University) | Kim, H Andrew (Baylor University)
We propose representing high-dimensional data in 2-dimensions using cliques mapped onto several planes. Currently, Multidimensional Scaling (MDS) projects every point onto an R space medium. However, this may not produce the most ideal result as some relations between points may exhibit higher stress than others. We propose utilizing cliques to extract a complete subset of points into separate facets in order to convey the most accurate distance representation as possible, therefore achieveing low stress in each instance.
Does Google Duplex Scare You? – Behavioral Signals - Conversational AI – Medium
Just in case you have not listened to the telephone calls placed by Google's latest conversational application code-named "Duplex" you should. Google Duplex can place calls and make restaurant reservations or book appointments to hair salons. Speech recognition and spoken dialogue technology has had the capability of successfully completing such tasks for over a decade now. What is exciting and frankly also a bit scary is that for the few (probably cherry-picked) recordings made available at the Google AI blog, the robotic caller is practically indistinguishable from a human. Google Duplex is not the first conversational system that passes the Turing test with flying colors for a few minutes: chatbots have been competing in this arena for years now.
Conversations Gone Awry: Detecting Early Signs of Conversational Failure
Zhang, Justine, Chang, Jonathan P., Danescu-Niculescu-Mizil, Cristian, Dixon, Lucas, Hua, Yiqing, Thain, Nithum, Taraborelli, Dario
One of the main challenges online social systems face is the prevalence of antisocial behavior, such as harassment and personal attacks. In this work, we introduce the task of predicting from the very start of a conversation whether it will get out of hand. As opposed to detecting undesirable behavior after the fact, this task aims to enable early, actionable prediction at a time when the conversation might still be salvaged. To this end, we develop a framework for capturing pragmatic devices---such as politeness strategies and rhetorical prompts---used to start a conversation, and analyze their relation to its future trajectory. Applying this framework in a controlled setting, we demonstrate the feasibility of detecting early warning signs of antisocial behavior in online discussions.
Zero-Shot Dialog Generation with Cross-Domain Latent Actions
Zhao, Tiancheng, Eskenazi, Maxine
This paper introduces zero-shot dialog generation (ZSDG), as a step towards neural dialog systems that can instantly generalize to new situations with minimal data. ZSDG enables an end-to-end generative dialog system to generalize to a new domain for which only a domain description is provided and no training dialogs are available. Then a novel learning framework, Action Matching, is proposed. This algorithm can learn a cross-domain embedding space that models the semantics of dialog responses which, in turn, lets a neural dialog generation model generalize to new domains. We evaluate our methods on a new synthetic dialog dataset, and an existing human-human dialog dataset. Results show that our method has superior performance in learning dialog models that rapidly adapt their behavior to new domains and suggests promising future research.
MojiTalk: Generating Emotional Responses at Scale
Zhou, Xianda, Wang, William Yang
Generating emotional language is a key step towards building empathetic natural language processing agents. However, a major challenge for this line of research is the lack of large-scale labeled training data, and previous studies are limited to only small sets of human annotated sentiment labels. Additionally, explicitly controlling the emotion and sentiment of generated text is also difficult. In this paper, we take a more radical approach: we exploit the idea of leveraging Twitter data that are naturally labeled with emojis. More specifically, we collect a large corpus of Twitter conversations that include emojis in the response, and assume the emojis convey the underlying emotions of the sentence. We then introduce a reinforced conditional variational encoder approach to train a deep generative model on these conversations, which allows us to use emojis to control the emotion of the generated text. Experimentally, we show in our quantitative and qualitative analyses that the proposed models can successfully generate high-quality abstractive conversation responses in accordance with designated emotions.
