We present a method for querying knowledge graphs through naturallanguage, emphasizing its application to the Greek language. It integrates NLP techniques with the capabilities of graph databases to enable seamless interaction with knowledge graphs through naturallanguage queries. Upon receiving a user's question in Greek language, we use linguistic analysis tools to convert it into a graph structure by employing predefined rules and adhering to a graph database schema. This methodology enables the handling of different question types and the efficient extraction of relations, ensuring accurate mapping of linguistic structures to database queries. The representation of a question as a knowledge graph enables its direct translation to a Cypher query, facilitating the extraction of related answers. The approach can handle complex questions and is language independent.

A synonym mining method is proposed by combining the character vector graph and noise robust learning method. The model uses paired word vectors pre-trained by ChatGPT to enhance entity semantic representation. Classify marks with noise. Then the cross optimal processing is carried out to identify the true and false marks. The two-layer construction system of knowledge extraction and knowledge fusion is constructed to realize the independent construction and answer of software engineering questions. The system effectively improves the efficiency of software project understanding and software reuse.

naturallanguageprocessing (NLP) is a common application for Artificial Intelligence. The goal is to provide language teachers with a simple to apply tool for topic model analyses to integrate into their classroom. The project also involves project based learning for students programming the actual AI web application. The original notion is to provide language teacher with AI methodology without requiring any technical knowledge in AI or any programming skills. naturallanguageprocessing provides various tools for word frequencies, but also topic modelling, allowing to track the relevance of topics over time in the media or in the literature. In collaboration with University of Technology linguistics, we intend to provide a corpus of classical English and German literature, as well as the option of uploading your own corpus which can be obtained from webscraping or other sources. A team of students of the vocational high school TGM Wien specialised in IT and Software Development is working on the design of the interactive GUI for this NLP application, learning in this way the methods of naturallanguageprocessing and Artrificial Intelligence in a project based setting. For this the statistical programming language R is utilized which already provides packages with implementation for naturallanguageprocessing and in addition the shiny package which allows to develop interactie web apps without additional web and app programming. A team of teachers supervises and supports the students during the development process, providing expertise in AI and NLP, in web and app programming, as well as server management. Two intended outcomes exist. Ont the one hand, we want our students to learn naturallanguageprocessing first hand through development of this application. On the other hand, we intend to obtain an interactive AI tool which can assist language teachers and their students on the long term in the classroom. In times of GPT3 and GPT4 dominating the media and per

The rapid advancement of artificial intelligence (AI) and machine learning (ML) technologies, particularly in large language models (LLMs) like the GPT series, has significantly impacted research and industrial applications. These models excel in various naturallanguageprocessing (NLP) tasks, including text generation, comprehension, and translation. However, harnessing these capabilities for academic research still presents challenges, particularly for early-career researchers navigating extensive literature. In this paper, we introduce AcawebAgent, an inventive AutoAgent specifically crafted to enhance the abilities of beginner researchers. It leverages the advanced generation and analysis capabilities of large language models (LLMs) to collect open academic knowledge from the web. AcawebAgent offers customized research reports that include in-depth overviews, practical applications, the latest developments, and future trajectories of specific research domains, thereby significantly diminishing the time and effort needed for comprehensive literature reviews and trend analyses.

A backbone of knowledge graphs are their class membership relations, which assign entities to a given class. As part of the knowledgeengineering process, we propose a new method for evaluating the quality of these relations by processing descriptions of a given entity and class using a zero-shot chain-of-thought classifier that uses a naturallanguage intensional definition of a class. We evaluate the method using two publicly available knowledge graphs, Wikidata and CaLiGraph, and 7 large language models. Using the gpt-4-0125-preview large language model, the method's classification performance achieves a macro-averaged F1-score of 0.830 on data from Wikidata and 0.893 on data from CaLiGraph. Moreover, a manual analysis of the classification errors shows that 40.9% of errors were due to the knowledge graphs, with 16.0% due to missing relations and 24.9% due to incorrectly asserted relations. These results show how large language models can assist knowledge engineers in the process of knowledge graph refinement. The code and data are available on Github (https://***/bradleypallen/evaluating-kg-class-memberships-using-llms).

The effectiveness of Large language Models (LLMs) in tasks involving reasoning is significantly influenced by the structure and formulation of the prompts, contemporary research in prompt engineering aims to help LLMs better understand the paradigms of reasoning question (e.g., CoT). However, these efforts have either struggled to effectively incorporate external knowledge into single prompt or integrating entire corpus information, often fails to significantly enhance the reasoning capabilities of LLMs. This paper introduces a novel prompting method that incorporates implicit hints that represent logical combinatorial relationships between known conditions in reasoning problems, guiding LLMs to think correctly in the initial steps of reasoning for such problems. Extensive and comprehensive experiment results on four different reasoning problem datasets indicate that our proposed method improved accuracy while maintaining efficiency.

This paper introduces an approach that integrates naturallanguageprocessing (NLP) and knowledge graphs with Reconfigurable Manufacturing Systems (RMS) to enhance flexibility and adaptability. We utilize a chatbot interface powered by GPT-4 and a structured knowledge base to simplify the complexities of manufacturing reconfiguration. This system not only boosts reconfiguration efficiency but also broadens accessibility to advanced manufacturing technologies. We demonstrate our methodology through an application in capability matching, showcasing how it facilitates the identification of assets for new product requirements. Our results indicate that this integrated solution offers a scalable and user-friendly approach to overcoming adaptability challenges in modern manufacturing environments.

This study provides an in-depth examination of LLaMA 3's performance on a domain-specific task, specifically classifying monetary policy texts. The aim is to categorize these texts as hawkish, dovish, or neutral by using a prompt to assess LLaMA 3's understanding of finance-related knowledge anticipated to be acquired during its pretraining. Experimental results demonstrate that LLaMA 3 has indeed developed the necessary commonsense knowledge to interpret monetary policy, as it surpasses both major and random baselines. To further understand its performance, we also analyze the consistency of its impressive results across different model inputs, including the number of tokens, nouns, and verbs.
