: 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.

The prefix "Tir" or "TIGER" often denotes TIGER/Line Shapefiles, which are core geographic products from the U.S. Census Bureau.

: Use libraries like geopandas (Python) for geographic data or ir_datasets for research benchmarks.

: These files contain selected geographic and cartographic information (roads, boundaries, water features) from the Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) database.

: 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

: 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.
