Perspective-Based Microblog Summarization †
Abstract
:1. Introduction
- We have developed three summarization methods for social media posts: entity-based, triple-based and social feature-focused summarization.
- We have developed the Multiple-View Summarization Framework (MVSF), which is capable of generating summaries based on multiple perspectives, such as political orientations, sentiments, or fake opinions, combining them with any of the three summarization methods. The framework provides greater flexibility of choosing summarization methods as well as combining different perspectives, generating fine-grained and personalized summaries tailored to the end-user’s preferences.
- Theoretical implications are the integration of multiple perspectives and extractive methods within a unified framework, in contrast to one-size-fits-all summarization. This enables comprehensive information extraction from social media content and constitutes an extended paradigm for summarization research. On the practical side, we have developed summarization algorithms for the MVSF to allow users to tailor summaries to their needs.
- Through extensive performance experiments, we compared the summaries generated by our entity-based and triple-based methods, both independently and in conjunction. When benchmarking the results against prominent summarization models from the literature, such as Bart-large-CNN 5, Text-To-Text-Transfer-Transformer (T5) [25], BertSum [26], and SBert [27], our summaries achieved a performance improvement of 14% in terms of Rouge scores.
- Our framework was effectively applied to an X/Twitter dataset of 18,047 COVID-19 vaccine-related tweets, demonstrating the flexibility of presenting different summaries of this topic.
- We leverage our MVSF to present a comparative analysis of fake and real news, to enhance its utility in discerning truth and misleading information distributed across social media platforms, which is increasingly important in today’s world.
- We have developed a user-friendly web prototype (http://ai4sg.njit.edu/ai4sg/Summarize, accessed on 1 September 2023) leveraging the power of OpenAI ChatGPT (text-davinci-003) [28] for text summarization. This application works within the MVSF, while not suffering from the hardware-intensive resource use of our algorithms. The application allows users to input text and customize summarization preferences based on the MVSF’s methods and perspectives, serving as an accessible perspective-based summarization tool.

6.1. Entity-Based Summarization (EbS)
- Identify the same events in triples using WordNet: Important entities can appear in semantically similar events that are expressed by different predicates/actions. Thus, we need to identify predicates expressing similar or identical meanings with different verbs, such as “offer”, “pass”, and “transfer”, or different forms of the same verb, e.g., “provide”, and “provided”, all of which express a similar meaning of “giving something to someone”. Groups of semantically similar verbs can be subsumed by one root verb, using the appropriate synset from WordNet [74]. A synset is a set of one or more synonyms. WordNet organizes synset into generalization hierarchies. A verb in a hierarchy that is the most general is referred to as a root verb. For triples using verbs expressing similar/identical meanings with different words or tense forms, we replaced the verbs as follows. To disambiguate the meaning of a predicate and find the closest synsets, we compared two methods and used a human evaluator to determine the better one. The first method is the Lesk algorithm [75]. Given a verb and the triple where it occurs, Lesk returns a synset that represents its context meaning. However, Lesk often failed at finding the correct synset. Among a set of 80 randomly picked triples, only 37 verb synsets were correctly identified, according to the human evaluator. The second method was that we selected “v.01” (primary meaning returned by WordNet) as the verb synset. Although this is a simple approach, it produced a better result (78/80) according to the human review. Therefore, we used the “v.01” meaning for each verb to find the root synset. For each synset vx.v.01 of the verb vx, we followed its hypernym (superclass) chain upward until reaching its root synset. We identified the frequent events by selecting triples whose root verbs occur more often than a threshold θ. Given a triple set TS = {ts1, ts2, …} where tsi = <s, p, o>, find tsj = <s, root(p), o>. We select triples that have frequent root verbs root(p), i.e., frequency(root(p)) > θ. We present the program to identify the synset hierarchy in Table 1, and an example synset hierarchy in Figure 2, where all verbs are summarized by “give.”
- Identifying Salient Entities: The second task in this method is to identify important entities to focus on. Each triple includes two entities, a subject and an object. As noted, this method is based on the entities (subject/object) that occur most often in the triple sets. To identify the frequencies of meaningful words, for each entity, we removed numbers, stop words, and words with fewer than three characters and performed lemmatization. If a preprocessed entity became an empty string, we removed its triple from the triple set. If a preprocessed subject consisted of more than two words, we removed all words except for the last two (which are likely to contain “most of the meaning”).
