While this specific filename appears in specialized data repositories, its structure suggests it belongs to one of the following two domains: 1. U.S. Census Bureau TIGER/Line Shapefiles
: 2021 was a significant year for large-scale IR benchmarks, such as the TREC 2021 Deep Learning Track, which released massive passage and document datasets. Tir_Al_2021-09_to_2021-12.zip
: If you are using these for machine learning, you would typically use the ir_datasets Python API or CLI to load the data for document ranking or answer extraction tasks. Guide for Using the Data While this specific filename appears in specialized data
: Use a tool like 7-Zip or WinRAR to extract the contents. Avoid moving individual files out of their subfolders, as spatial and IR data often rely on strict directory structures. : If you are using these for machine
: Once extracted, the .zip will contain multiple files including .shp , .shx , and .dbf which must be kept together to function correctly. 2. Information Retrieval (IR) Datasets
: They are typically used in Geographic Information Systems (GIS) software like ArcGIS or QGIS for mapping and spatial analysis.
: Check for a README.md or metadata.xml file within the zip to confirm the specific geographic region or dataset version. Loading : For GIS : Open the .shp file in QGIS or ArcMap .
