TIBURON DOWNLOAD PAGE

Tiburon is a tree transducer package written by Jonathan May at USC/ISI. You may also be interested in Carmel, the very fine finite-state (string) transducer package written by Jonathan Graehl, which was the inspiration for Tiburon, and can be found here

Tiburon is designed to handle weighted regular tree grammars, context-free grammars, and both tree-to-tree and tree-to-string transducers, and can perform composition, intersection, application, determinization, inside/outside training, pruning, return k-most likely trees, Viterbi derivations, and other useful things.

Tiburon is written in java, and thus should be able to run on your machine. However, if you don't have java, you should get it first, from here (at least version 1.5 is required).

Here is a PDF tutorial on Tiburon.

Active users of Tiburon are strongly encouraged to subscribe to the Tiburon notification mailing list by following the link here, or by sending an email containing the word "subscribe" in either the subject or body to tiburon-request@mailman.isi.edu. This is an extremely low-traffic list. It will only contain messages about new releases of Tiburon and is likely to be the most up-to-date source of information of changes to the system.

LICENSE AGREEMENT

This License Agreement (the "Agreement") is entered, effective this date, by and between University of Southern California, and the individual executing this Agreement below as "Licensee" (hereinafter, the "Licensee").

WHEREAS, USC has developed the Tiburon package and related documentation (the "Software"); and

WHEREAS, Licensee desires, and USC is willing to grant to Licensee, a license to use the Software in accordance with this Agreement;

NOW, in consideration of the foregoing, the mutual covenants hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1. USC hereby grants Licensee a royalty-free, non-exclusive, non-transferable right to use the Software as follows solely for a Non-Commercial Purpose:

(a) Licensee may prepare derivative works (the "Derivative Works") which are based on or incorporate all or part of the Software, including, without limitation, works (the "Adaptations") which
(i) are translations of all or part of the Software into different programming languages, or
(ii) are revisions, improvements or corrections to all or part of the Software, provided that, Licensee shall treat all Derivative Works as Software under this Agreement; and
(b) Licensee may make only such copies of the Software as are necessary for Licensee's development of the Derivative Works.

2. All copies of the Software and Derivative Works prepared in accordance with paragraph 1 shall retain the copyright notice appearing in the Software. If the Software includes computer programs in object code form, Licensee shall not de-compile, reverse engineer or disassemble such programs.

3. As used in this Agreement, "Non-Commercial Purpose" means use of the Software and Derivative Works solely for education or research. "Non-Commercial Purpose" excludes, without limitation, any use of the Software or Derivative Works for, as part of, or in any way in connection with a product (including software) or service which is sold, offered for sale, licensed, leased, loaned or rented.

4. Licensee hereby grants USC a non-exclusive, royalty-free, fully paid-up, worldwide, perpetual license to:

(a) Reproduce, prepare derivative works based on and distribute all or part of the Adaptations; and

(b) Make, have made, use, offer to sell, sell, license or import any products (including software) or services under any intellectual property rights owned or licensed by Licensee which relate to
(i) all or part of the Adaptations (including as executed by a CPU), or
(ii) methods or concepts embodied in, or implemented through the execution by a CPU of, the Adaptations. If the Software includes documentation that identifies a contact person at USC, Licensee shall provide such person with feedback concerning Licensee's Adaptations and, if requested by USC, provide such person with source code copies of Licensee's Adaptations.

5. This Agreement is personal between USC and Licensee. No ownership interest in the Software (or the copy of which is provided by USC pursuant to paragraph 1) is transferred to Licensee. Licensee's interest in the Derivative Works is limited solely to Licensee's additions and the Derivative Works are subject in their entirety to USC's intellectual property rights. USC may assign or transfer to any company or person, or grant to any company or person a license or sublicense under, all or part of its interest in any rights to the Software, this Agreement, or any license granted to USC hereunder. Licensee may not assign, transfer or sublicense Licensee's rights hereunder without the written consent of USC.

6. USC may terminate this Agreement at any time by sending written notice of termination to Licensee at the address specified below. Termination shall be effective as provided in the notice. Unless the notice shall provide otherwise, upon termination, Licensee shall destroy all copies of the Software and Derivative Works. Licensee's obligations under this Agreement, including any rights granted to USC pursuant to paragraph 5, shall survive and continue after termination.

7. Licensee shall not, directly or indirectly, export the Software or any Derivative Work to any country to which such export is prohibited by law.

8. Licensee agrees to comply with all export laws and restrictions and regulations of the United States or foreign agencies or authorities, and not to export or re-export the Software or any direct product thereof in violation of any such restrictions, laws or regulations, or without all necessary approvals. Neither the Software nor the underlying information or technology may be downloaded or otherwise exported or re-exported

(i) into Cuba, Iran, North Korea, Sudan, Syria, Serbia, Taliban-controlled portions of Afghanistan, or any other country subject to U.S. trade sanctions covering the Software, to individuals or entities controlled by such countries, or to nationals or residents of such countries other than nationals who are citizens or lawfully admitted permanent residents of the United States and not currently domiciled in countries subject to such sanctions; or
(ii) to anyone on the U.S. Treasury Departmentīs list of Specially Designated Nationals and Blocked Persons or the U.S. Commerce Departmentīs Table of Denial Orders. By downloading or using the Software, Licensee agrees to the foregoing and represents and warrants that it complies with these conditions.

9. USC has no obligation to support or maintain the Software and grants Licensee this right to use the Software "AS IS". LICENSEE ASSUMES TOTAL RESPONSIBILITY AND RISK FOR LICENSEE'S USE OF THE SOFTWARE. USC DOES NOT MAKE, AND EXPRESSLY DISCLAIMS, ANY EXPRESS OR IMPLIED WARRANTIES, REPRESENTATIONS OR ENDORSEMENTS OF ANY KIND WHATSOEVER, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND THE WARRANTIES OF TITLE OR NON-INFRINGEMENT. IN NO EVENT SHALL USC BE LIABLE FOR

(a) ANY INCIDENTAL, CONSEQUENTIAL, OR INDIRECT DAMAGES (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF PROFITS, BUSINESS INTERRUPTION, LOSS OF PROGRAMS OR INFORMATION, AND THE LIKE) ARISING OUT OF THE USE OF OR INABILITY TO USE THE SOFTWARE, EVEN IF USC OR ANY OF ITS AUTHORIZED REPRESENTATIVES HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES,

(b) ANY CLAIM ATTRIBUTABLE TO ERRORS, OMISSIONS, OR OTHER INACCURACIES IN THE SOFTWARE, OR

(c) ANY CLAIM BY ANY THIRD PARTY.

10. This Agreement shall be governed by and construed in accordance with the laws of the State of California, USA, applicable to agreements made and to be performed wholly therein without regard to its conflicts of law rules. Any cause of action or claim Licensee may have with respect to the Software must be brought within one (1) year after the claim or cause of action arises or such claim or cause of action is barred. USC's failure to insist upon or enforce strict performance of any provision of this Agreement is not a waiver of any provision or right.

11. If a dispute arises out of, or relates to, this Agreement or the subject matter of this Agreement, either party may submit the dispute to a sole mediator selected by the parties or, at any time prior to selection of a sole mediator, to mediation by the American Arbitration Association ("AAA"). If not thus resolved, it shall be referred to a sole arbitrator selected by the parties or to the AAA for arbitration. The arbitration shall be governed by the United States Arbitration Act, shall be conducted in the County of Los Angeles, California, USA, and judgment on the award may be entered by any court having jurisdiction. The arbitrator shall not limit, expand or modify the terms of the Agreement nor award damages in excess of compensatory damages, and each party waives any claim to excess damages. A request by a party to a court for interim protection shall not affect either party's obligation hereunder to mediate and arbitrate. Each party shall bear its own expenses and an equal share of all cost and fees of the mediation and/or arbitration. Any arbitrator selected shall be competent in the legal and technical aspects of the subject matter of this Agreement. The content and result of mediation and/or arbitration shall be held in confidence by all participants.

I certify that I am not a national or a resident of Cuba, Iran, North Korea, Sudan, Syria, Serbia, Taliban-controlled portions of Afghanistan, or any other country subject to U.S. trade sanctions, nor, to the best of my knowledge, have I been designated a Specially Designated National, Blocked Person, or otherwise been denied export-related privileges by the United States Government.
