3.4 Data Cleaning
The GeoNames dataset contains a large number of entries, many of which contain errors or inconsistencies. In order to achieve accurate results in our natural language processing tasks, we needed to clean the data.
We began by removing duplicates and entries with missing values. We then standardized the location names by converting them to title case and removing any extraneous characters or punctuation. For example, we converted "new york city" to "New York City" and removed any parentheses or slashes.
Next, we identified and corrected spelling errors using a spell-checking algorithm. We also corrected inconsistent name formats, such as different spellings of the same location or variations on abbreviations (e.g. "St." versus "Saint").
Finally, we used regular expressions to identify and remove any remaining extraneous characters or formatting issues. For example, we removed any trailing whitespace or periods and standardized the use of hyphens and spaces in location names.
Overall, our data cleaning process improved the accuracy and consistency of the GeoNames dataset, making it more suitable for natural language processing tasks.
