A process and system for database storage and retrieval are described along with methods for obtaining semantic profiles from a training text corpus. A neural network (103) is used to extract semantic profiles (109) from text corpus. A new set of documents obtained from the Internet is then submitted for processing to same neural network, which computes the semantic profile representation for these pages using the semantic relations (106) learned from profiling the training documents.

Why it's free to use
- Filed August 29, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 29, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
