Is Longman English Dictionary as database available for public or should I digitalise it?
I plan to create an app based on Longman English Dictionary, but I need the database somehow. Any idea how?
This particular dictionary's legal notice says that:
Users are not entitled to [...] transmit [..] it on any other website without the express permission of Pearson.
You must not use data mining, robots, scraping or similar data gathering or extraction methods on any part of this Site without our express prior written consent (my emphasis)
So either contact them, or use a more open dictionary.
See this list of open English dictionaries.
