The labor market is experiencing rapid and continual shifts in required skills and competencies, driven by technological advancement and evolving industry structures. Within this dynamic environment, candidates increasingly face challenges in orienting their career development, requiring them to continuously update their knowledge and capabilities to meet contemporary job requirements; this need is particularly necessary for new entrants to the labor market, who must cultivate a comprehensive understanding of current labor-market conditions. To address these issues, this study proposes an enterprise recruitment framework grounded in a career path knowledge graph, capturing occupations, skill requirements, and career transitions using standardized taxonomies enriched with job-posting data. The framework integrates transformer-based embeddings, large language models, and knowledge-graph reasoning to support efficient and reliable CV assessment, CV-JD matching and career guidance.

LegalLens is a competition organized to encourage advancements in automatically detecting legal violations. This paper presents our solutions for two tasks Legal Named Entity Recognition (L-NER) and Legal Natural Language Inference (L-NLI). Our approach involves fine-tuning BERT-based models, designing methods based on data characteristics, and a novel prompting template for data augmentation using LLMs. As a result, we secured first place in L-NER and third place in L-NLI among thirty-six participants. We also perform error analysis to provide valuable insights and pave the way for future enhancements in legal NLP. Our implementation is available at https://github.com/lxbach10012004/legal-lens/tree/main

In legal text processing and reasoning, one normally performs information retrieval to find relevant documents of an input question, and then performs textual entailment to answer the question. The former is about relevancy whereas the latter is about affirmation (or conclusion). While relevancy and affirmation are two different concepts, there is obviously a connection between them. That is why performing retrieval and textual entailment sequentially and independently may not make the most of this mutually supportive relationship. This paper, therefore, propose a multi–task learning model for these two tasks to improve their performance. Technically, in the COLIEE dataset, we use the information of Task 4 (conclusions) to improve the performance of Task 3 (searching for legal provisions related to the question). Our empirical findings indicate that this supportive relationship truly exists. This important insight sheds light on how leveraging relationship between tasks can significantly enhance the effectiveness of our multi-task learning approach for legal text processing.
