MMTab is a large-scale multimodal instruction-tuning dataset for enhancing and evaluating the visual table understanding ability of multimodal LLMs. It contains diversified table images and instruction following data, covering 15 tabular tasks, e.g., table question answering, table2text, table structure understanding. The dataset is divided into three parts: MMTab-pre (pre-training), MMTab-instruct (instruction fine-tuning), and MMTab-eval (evaluation). Each part contains different amounts of table images and sample data, and the data format follows the LLaVA dialogue format. The dataset is constructed based on 14 publicly available table datasets from 8 domains, and the original textual tables are converted into table images using scripts. The primary use of MMTab is research on large multimodal models and chatbots, and the primary intended users are researchers and hobbyists in computer vision, natural language processing, machine learning, and artificial intelligence. The limitations of the dataset include its focus on single-table scenarios in English, lack of consideration for multi-table scenarios and broader language coverage, and the fact that the table images are mainly from high-quality datasets, not covering low-quality images.

数据集创建

为了支持多模态表格理解的多模态大型语言模型(MLLMs)的开发和评估,我们基于14个公开可用的8个领域的表格数据集构建了MMTab。我们精心设计脚本,将这些数据集中的原始文本表格转换为突出广泛表格结构和样式的表格图像,并将所有特定任务样本转换为具有统一格式的多模态指令微调样本<表格图像,输入请求,输出响应>。

预期用途

主要预期用途: MMTab 主要用于大型多模态模型和聊天机器人的研究。

主要预期用户: MMTab 的主要预期用户是计算机视觉、自然语言处理、机器学习和人工智能领域的研究人员和爱好者。

限制

首先,该数据集主要关注单个英语表格。多表格场景和更广泛的语言覆盖尚未考虑。其次,MMTab 基于精心选择的表格数据集中的真实世界表格,并包含由自动化脚本渲染的多样化高质量表格图像。然而,现实世界中的表格图像可能是低质量的,例如模糊、手写或不完整的表格图像。为了进一步缩小学术研究和实际应用场景之间的差距,未来可以收集更多样化的现实世界表格图像,并构建相应的指令跟随数据。

Canadian Census

**Overview** The data package provides demographics for Canadian population groups according to multiple location categories: Forward Sortation Areas (FSAs), Census Metropolitan Areas (CMAs) and Census Agglomerations (CAs), Federal Electoral Districts (FEDs), Health Regions (HRs) and provinces. **Description** The data are available through the Canadian Census and the National Household Survey (NHS), separated or combined. The main demographic indicators provided for the population groups, stratified not only by location but also for the majority by demographical and socioeconomic characteristics, are population number, females and males, usual residents and private dwellings. The primary use of the data at the Health Region level is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information to monitor, plan, implement and evaluate programs to improve the health of Canadians and the efficiency of health services. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the health region data to raise awareness about health, an issue of concern to all Canadians. The Census population counts for a particular geographic area representing the number of Canadians whose usual place of residence is in that area, regardless of where they happened to be on Census Day. Also included are any Canadians who were staying in that area on Census Day and who had no usual place of residence elsewhere in Canada, as well as those considered to be 'non-permanent residents'. National Household Survey (NHS) provides demographic data for various levels of geography, including provinces and territories, census metropolitan areas/census agglomerations, census divisions, census subdivisions, census tracts, federal electoral districts and health regions. In order to provide a comprehensive overview of an area, this product presents data from both the NHS and the Census. NHS data topics include immigration and ethnocultural diversity; aboriginal peoples; education and labor; mobility and migration; language of work; income and housing. 2011 Census data topics include population and dwelling counts; age and sex; families, households and marital status; structural type of dwelling and collectives; and language. The data are collected for private dwellings occupied by usual residents. A private dwelling is a dwelling in which a person or a group of persons permanently reside. Information for the National Household Survey does not include information for collective dwellings. Collective dwellings are dwellings used for commercial, institutional or communal purposes, such as a hotel, a hospital or a work camp. **Benefits** - Useful for canada public health stakeholders, for public health specialist or specialized public and other interested parties. for health surveillance and population health research. for monitoring, planning, implementation and evaluation of health-related programs. media agencies may use the health regions data to raise awareness about health, an issue of concern to all canadians. giving the addition of longitude and latitude in some of the datasets the data can be useful to transpose the values into geographical representations. the fields descriptions along with the dataset description are useful for the user to quickly understand the data and the dataset. **License Information** The use of John Snow Labs datasets is free for personal and research purposes.
