This morning we upgraded OpenCalais to release 4.7. Our focus with 4.7 was on a significant improvement in the detection and disambiguation of companies as well as some behind-the-scenes tune-ups and bug fixes.
If your content contains company names you should already be seeing a significant improvement in detection and disambiguation. While company detection has always been very good in OpenCalais, now it's great.
If you're one of our high-volume commercial clients (1M+ transactions per day), we'll be rolling out your upgrade toward the end of the month.
And, remember, you can always drop by the OpenCalais viewer for a quick test or exploration of OpenCalais with zero programming involved.
