Stance detection on social media has attracted significant attention recently. However, for a hot event, it is not easy to determine the stance of a comment on a given target, because there is complex comment-target-event-stance relationship behind it. To alleviate this problem, a new fusion method is proposed, which integrates explicit stance label and brief event background into BERT-based stance classifier. By fine-tuning the BERT model, it learns to reason about accurate stances based on the fused information. Experiments on a Weibo stance detection dataset demonstrate the effectiveness of the method.

The overwhelming volume of scientific documents necessitates automatic summarization to assist researchers in efficiently finding relevant data, making informed decisions, and retrieving appropriate answers to their queries. Query-based automatic summarization is to provide a textual summary related to user’s initial query. Most of the previous approaches in query-based summarization, only consider the user’s initial query to model user’s information need, and rarely rely on additional interaction between user and system. This study proposes an interactive multi-document summarization system designed to assist researchers in processing scientific documents. The interactive approach is necessary to refine document selection and improve summary relevance through user feedback. The system utilizes advanced natural language processing techniques to retrieve and summarize relevant content, including query-based summarization to tailor summaries to specific user queries. By incorporating user-generated questions, the system enhances the coherence and pertinence of summaries. The system is tested and evaluated for Persian language. Despite the lack of labeled datasets in the Persian, the proposed approach demonstrates effective summarization through unsupervised methods. User evaluations confirm the system’s potential to significantly improve information retrieval and comprehension in scientific research. © 2024 IEEE.

The field of space science and applications, rich in domain knowledge, has witnessed research on domain knowledge extraction and the preliminary construction of domain knowledge graphs. Entity linking serves as a fundamental component for intelligent applications of knowledge graphs. Recently, the retriever-reader paradigm, inspired by question-answering tasks, has advanced the development of entity linking. However, the existing studies overlook the relationships between entities, resulting in the lack of global consistency in the predictions. Furthermore, they struggle to deal with redundant entities effectively. We propose a Global-Aware Entity Linking Model (GAEL) to address these issues. GAEL employs incremental training during model training, integrating linking results in successive rounds. By incorporating the entity information predicted in previous rounds into new training inputs, GAEL continuously optimizes semantic information and strengthens interactions between candidate entities, which helps to identify potential entities corresponding to mentions. Besides, GAEL utilizes a novel entity screening mechanism that encodes candidate entities and input text separately and ranks them based on semantic similarity, effectively resolving the issue of multiple entities corresponding to the same mention. Experimental results demonstrate that GAEL significantly improves entity linking performance on datasets in the field of space science and applications, as well as on multiple public datasets. © 2024 IEEE.

natural language processing (NLP) is an interdisciplinary field that enables machines to understand and generate human language. One of the crucial steps in several NLP tasks, such as emotion and sentiment analysis, text similarity, summarization, and classification, is transforming textual data sources into numerical form, a process called vectorization. This process can be grouped into traditional, semantic, and contextual vectorization methods. Despite their advantages, these high-dimensional vectors pose memory and computational challenges. To address these issues, we employed a sliding window technique to partition high-dimensional vectors, aiming not only to enhance computational efficiency but also to detect emotional information within specific vector dimensions. Our experiments utilized emotion lexicon words and emotionally labeled sentences in both English and Turkish. By systematically analyzing the vectors, we identified consistent patterns with emotional clues. Our findings suggest that focusing on specific sub-vectors rather than entire high-dimensional BERT vectors can capture emotional information effectively, without performance loss. With this approach, we examined an increase in pairwise cosine similarity scores within emotion categories when using only sub-vectors. The results highlight the potential of the use of sub-vector techniques, offering insights into the nuanced integration of emotions in language and the applicability of these methods across different languages. © 2024 by SCITEPRESS – Science and Technology Publications, Lda.

In this paper we introduce a new Controlled natural language (CNL) known as "Noam". It is used to express cyber security knowledge and for reasoning over it. The approach follows examples set by other domain-specific languages and constrained grammars, but is highly unusual due to its singular focus on cyber security. Like most CNLs Noam is both human-readable and machine-solvable, thus fulfilling important assurance requirements with respect to transparency and explainability. The language seeks to address a growing problem faced by security engineers and architects;namely, that their endeavours are constrained by the complexity and sheer interconnectedness of the systems they protect. This is further compounded by year-on-year vulnerability disclosure rates and diversification of the Tactics, Techniques and Procedures used by threat actors. Our approach is analogical in which the Noam CNL is used to construct a system model, instrument it with data from the real environment and apply functional programming techniques in order to 'solve-for' certain conditions of interest. The intention is to demonstrate the value of CNLs and semantic reasoning within cyber security, framed in the context of improving the information available to security engineers, architects and other decision-makers.

The task of image caption generation aims to automatically produce natural language descriptions that match the content of images, integrating the fields of machine vision and natural language processing, which holds significant theoretical and practical value. Inspired by top-down attention mechanisms, this paper proposes an innovative attention model. Utilizing the output of pretrained object detection networks as prior knowledge for images, the model guides the generation of natural language descriptions. By directly incorporating the results of object detection as attention inputs into the text generation network, the model effectively focuses on key descriptive regions of images, thereby significantly enhancing performance. On public Chinese image captioning datasets, this model demonstrates substantial advantages in metrics such as BLEU-4 and METEOR. © 2024 IEEE.

In the development of new industries, there is a growing demand for innovative materials. However, locating such materials is a laborious and time-consuming endeavor. In response, there has been a shift toward studying new materials more efficiently using existing material science research knowledge. There has been an increase in the number of materials science-related papers over the past two decades, and attempts to use them for research purposes have increased as the methods have been systematized. Past research papers, for instance, can be used to predict new materials or obtain optimal synthesis parameters for materials with the desired properties. In this movement, natural language processing (NLP) is a crucial technology. In the past decade, NLP has emerged as one of the most rapidly expanding areas of artificial intelligence, proving to be a valuable tool for processing language-based data. In this review, we will examine how NLP is used in the materials science literature, what processes it can be used for, and the primary NLP technologies currently in use, with a particular focus on specific use cases. We will also discuss this approach's limitations.

Large language models excel in various natural language processing tasks but often struggle with knowledge-intensive queries, particularly those involve rare entities or require precise factual information. This paper presents a novel framework that enhances capabilities of an LLM-based question answering system by incorporating structured knowledge from knowledge graphs. Our approach employs entity extraction, semantic similarity scoring, and adaptive graph exploration to efficiently navigate and extract relevant information from knowledge graphs. The core of the presented solution is a knowledge graph-enhanced language model process that iteratively refines subgraph exploration and answer generation, complemented by a fallback mechanism for robustness across diverse question types. Experiments on location-based questions from the Entity Questions dataset demonstrate significant improvements in the quality of responses. Using the Gemini 1.5 Flash model, our system achieved an accuracy increase from 36% to 71% for partially correct answers and from 22% to 69% for exactly correct answers, as evaluated by human assessors. This approach offers a promising direction for developing more reliable and accurate question answering systems, particularly for queries involving long-tail entities or specific factual knowledge. © 2024 IEEE.

As a key medium to eliminate language barriers and enhance international understanding, English translation software plays an important role in the rapid and accurate circulation of information. This article aims to explore the application of deep learning and natural language processing technology in the optimization of English translation software, and proposes an innovative automatic assessment and optimization algorithm. Traditional optimization methods of translation software are limited by manual features and rules, and it is difficult to adapt to complex and changeable translation needs. Therefore, this study combines the powerful feature learning ability of deep learning with the deep understanding of language structure by natural language processing, and designs a novel algorithm. By automatically extracting useful features from the bilingual corpus and learning the complex mapping relationship between the source language and the target language, the algorithm has significantly improved the translation quality. The results show that, compared with traditional methods, the method proposed in this article is excellent in reducing word error rate and improving translation fluency, which provides a new direction for the development of machine translation. © 2024 IEEE.

With the rise of social media, hate speech has become increasingly widespread and potent. A notable type of hate speech is dehumanization, which has been hypothesized to enable harmful behavior towards members of society. The large-scale automatic identification of dehumanizing language and its targets can potentially aid online content moderation efforts. We compiled a list of dehumanizing terms (DHT), which refer to words that strips individuals or groups of their humanity, and target identities (TI), the individuals or groups that are dehumanized. Using this DHT list, we selected Reddit conversations for annotation of TI. As a result, we created the first dataset of English conversation threads where both DHT and their TI are annotated. We show that large pre-trained language models can be used effectively to automatically verify DHTs and identify their TIs. © 2024 Copyright held by the owner/author(s).
