What this record means
The record shows the WORDNET mark is cancelled, not live, and was owned by NICE LTD., a public limited company organized in Israel; it was registered on the Principal Register for Class 009 covering “apparatus and instruments for recording and transmission of sound or data, namely tape and disc recorders and players, digital interfaces, and structural parts thereof.” A later‑filed Section 8 declaration was not accepted, so the USPTO cancelled the registration on April 17 2020, and the supplied history contains no oppositions, cancellations by a third party, or other enforcement activity. Because the registration was limited to that specific class of electronic recording equipment, the closest record‑based concern for a similar name would be in the same or closely related hardware field; the record does not extend to unrelated goods or services. I'd treat this as a meaningful concern if you plan to use WORDNET for similar audio‑data devices, but it does not automatically block use in other categories.
