Logical table-to-text generation (LT2T) seeks to produce logically faithful textual descriptions base on tables. Current end-to-end LT2T models, which use descriptions directly as learning objectives, frequently face challenges in maintaining logical faithfulness due to the lack of a reasoning knowledge. Recent research have introduced reasoning knowledge generated by models for LT2T task, but the noise along with it limited its performance. We therefore propose a framework reasoning knowledge filter that leverages the collaboration between large language models and smaller models to filter data points with high-quality reasoning knowledge. This framework aims to provide highly matched table, description and reasoning knowledge triplets for LT2T. The results obtained on LogicNLG database demonstrate that the efficiencies of the method in this paper has achieved optimal performance with a reduced amount of data. Specifically, it enhances SP-Acc by 1.4 points and NLI-Acc by 0.7 points compared to the current state-of-the-art model.

With the continuous growth of multi-modal data on social media platforms, traditional Named Entity Recognition has rendered insufficient for handling contemporary data formats. Consequently, researchers proposed Multi-modal Named Entity Recognition (MNER). Existing studies focus on capturing the visual regions corresponding to entities to assist in entity recognition. However, these approaches still struggle to mitigate interference from visual regions that are irrelevant to the entities. To address this issue, we propose an innovative framework, Visual Cue Refinement in MNER(VCRMNER) using CLIP Prompts, to accurately capture visual cues (object-level visual regions) associated with entities. We leverage prompts to represent the semantic information of entity categories, which helps us assess visual cues and minimize interference from those irrelevant to the entities. Furthermore, we designed an interaction transformer that operates in two stages—first within each modality and then between modalities—to refine visual cues by learning from a frozen image encoder, thereby reducing differences between text and visual modalities. Comprehensive experiments were conducted on two public datasets, Twitter15 and Twitter17. The results and detailed analyses demonstrate that our method exhibits robust and competitive performance.

Interactive-predictive machine translation (IPMT) is a translation mode which combines machine translation technology and human behaviours. In the IPMT system, the utilization of the prefix greatly affects the interaction efficiency. However, state-of-the-art methods filter translation hypotheses mainly according to their matching results with the prefix on character level, and the advantage of the prefix is not fully developed. Focusing on this problem, this paper mines the deep constraints of prefix on syntactic level to improve the performance of IPMT systems. Two syntactic subtree matching rules based on phrase structure grammar are proposed to filter the translation hypotheses more strictly. Experimental results on LDC Chinese-English corpora show that the proposed method outperforms state-of-the-art phrase-based IPMT system while keeping comparable decoding speed.
