🧠 Entity Linking (EL) over Tabular Data – Company Table

Entity linking is the task of connecting textual mentions in data to their corresponding entries in a structured knowledge base — in this case, Wikidata.

In this challenge, your goal is to link specific cells in a tabular dataset of companies to the corresponding Wikidata QIDs. The data includes company names, countries, founders, headquarters, and other attributes. Your system must determine the correct Wikidata entity for each annotated cell.

📘 The Dataset

You are provided with a CSV file called companies_test.csv, representing rows of company-related information. However, not all cells need to be annotated — only specific ones (e.g., company names or headquarters).

Each cell to be annotated is uniquely identified by a string id in the format:

companies_test-row_index-column_index

For example, the cell in row 3, column 0 is:

companies_test-3-0
