- Title: On Informative Tweet Identification For Tracking Mass Events
- Authors: Renato Stoffalette Jo\~ao
- Abstract summary: We investigate machine learning methods for automatically identifying informative tweets among those that are relevant to a target event.
We propose a hybrid model that leverages both the handcrafted features and the automatically learned ones.
Our experiments on several large datasets of real-world events show that the latter approaches significantly outperform the former.

- Abstract: Twitter has been heavily used as an important channel for communicating and
discussing about events in real-time. In such major events, many uninformative
tweets are also published rapidly by many users, making it hard to follow the
events. In this paper, we address this problem by investigating machine
learning methods for automatically identifying informative tweets among those
that are relevant to a target event. We examine both traditional approaches
with a rich set of handcrafted features and state of the art approaches with
automatically learned features. We further propose a hybrid model that
leverages both the handcrafted features and the automatically learned ones. Our
experiments on several large datasets of real-world events show that the latter
approaches significantly outperform the former and our proposed model performs
the best, suggesting highly effective mechanisms for tracking mass events.

We propose a Two-Stage Prefix-Enhanced MLLM (TSPE) approach for event attribution in movie videos.
In the local stage, we introduce an interaction-aware prefix that guides the model to focus on the relevant multimodal information within a single clip.
In the global stage, we strengthen the connections between associated events using an inferential knowledge graph.

Speech event detection is crucial for multimedia retrieval, involving the tagging of both semantic and acoustic events.
This paper tackles two primary challenges in speech event detection: the continual integration of new events without forgetting previous ones, and the disentanglement of semantic from acoustic events.
We propose a novel method, 'Double Mixture,' which merges speech expertise with robust memory mechanisms to enhance adaptability and prevent forgetting.

We present a novel task, identifying manipulation of news on social media, which aims to detect manipulation in social media posts and identify manipulated or inserted information.
To study this task, we have proposed a data collection schema and curated a dataset called ManiTweet, consisting of 3.6K pairs of tweets and corresponding articles.
Our analysis demonstrates that this task is highly challenging, with large language models (LLMs) yielding unsatisfactory performance.
