Added fast in-memory BM25 text search for more accurate and faster identification of country in the near parameter.
More tinkering on our receipt scanning accuracy benchmarking tool, so we can streamline the process to ingest data from the feedback API.
We have also improved the payment types extraction to support a wider variety of payment processors.
We improved the way we handle receipts from France and Hong Kong. Particularly, to improve the accuracy level for the total amount.
We added a new feature to return the merchant postal code when detected on a receipt. This is great if you are using TAGGUN to validate receipt as proof of purchase for digital loyalty campaigns.
We have added the ability to detect enhanced merchant address work for Australian market.
We have upgraded our third-party dependencies to avoid any security vulnerabilities. A nice side effect is we now have a brand new Swagger UI for our API tester and documentation.

Fighting spammers. We had to implement some high-level protection against abuse on our demo site. Annoying cat and mouse game. But, fun stuff.
Occasionally, the PDF rendering can cause some issues in our API. We have fixed this with a fork of Google's PDFium library for node. And we have released it as an open-source package at https://www.npmjs.com/package/@taggun/pdfium
We rolled out a new model to detect location from the text of the receipts and invoices.
Previously we relied on the "near" parameter of IP address to detect the location... Now, we have improved the algorithm to better detect the city and country name from the receipt.
We use a list of city and country names from https://www.geonames.org/countries/ with a population above 150,000 to train the NER model.
Previously, if the request header content-type is not set as application/json, we would still process the content as JSON type. We're now performing stricter checks on the content-type request header for safety.
For those who love to get the accurate time from the receipts, good news, you can now set "extractTime" to true and we will return the time if we can detect it from the receipt.
Occasionally, a valid PDF file will be deemed as unsafe by our security check... Now we allow some tolerance for PDF files with an unexpected signature in the file bytes.
For those who serve Australian customers, Australia Business Number (ABN) number is mandatory in Australian invoices. We now integrate with the Australian government's API to return enriched data from the ABN registry.
Added new feature to detect location from the text of the receipts and invoices.
We received feedback that the 418 error status code is non-standard and causing their application to retry the requests if the file is not a receipt. So, we now return success code 200 with empty results for each property if there is no text detected on the receipt.
If the file type is PDF, and content-type is "application/octet-stream" (a common mistake made by other applications), we will now try to handle this as a PDF file gracefully for you as application/pdf content-type.
If we detect unmatched content-type and file type for security check purposes, we now return the 400 error status code.
Added new feature to integrate with Australian Business Number (ABN) and return enriched data from ABN registry.

Publish this help documentation for Taggun. Even though Swagger documentation is great for up-to-date information for the APIs, there are still other aspects in Taggun that I would like to share with everyone.
/api/article/v1/verbose/file endpoint to perform OCR other than receipt. This is useful to just do a simple image-to-text dump and capture any metadata like dates and amounts that are found on the image.
Modify receipt endpoints and the structure of the response uniform and easier to understand.
Added a dump of all detected amounts on a receipt to meet a feature request from a Reddit user. Follow the link to see the Reddit post.
Started Taggun blog. Apparently blog is the most effective tool for digital marketing?!!. Check it out --> https://blog.taggun.io
Woohoo... Taggun has a bot!! His name is Marvin and he is Taggun's admin assistant. You can ask him to do a few basic administrative tasks now. Get to know more about Marvin.
