REQUIREMENTS\n\nA Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:\n\na) it complies with the terms and conditions of this Agreement; and\n\nb) its license agreement:\n\ni) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;\n\nii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;\n\niii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and\n\niv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange. \n\nWhen the Program is made available in source code form:\n\na) it must be made available under this Agreement; and\n\nb) a copy of this Agreement must be included with each copy of the Program. \n\nContributors may not remove or alter any copyright notices contained within the Program.\n\nEach Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.\n\n4. COMMERCIAL DISTRIBUTION\n\nCommercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor (\"Commercial Contributor\") hereby agrees to defend and indemnify every other Contributor (\"Indemnified Contributor\") against any losses, damages and costs (collectively \"Losses\") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.\n\nFor example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.\n\n5. NO WARRANTY\n\nEXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN \"AS IS\" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.\n\n6. DISCLAIMER OF LIABILITY\n\nEXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.\n\n7. GENERAL\n\nIf any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.\n\nIf Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.\n\nAll Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.\n\nEveryone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.\n\nThis Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation." }, { "path": "FuzzyString/SorensenDiceDistance.cs", "content": "using System;\nusing System.Collections.Generic;\nusing System.Linq;\nusing System.Text;\nusing System.Threading.Tasks;\n\nnamespace FuzzyString\n{\n public static partial class ComparisonMetrics\n {\n public static double SorensenDiceDistance(this string source, string target)\n {\n return 1 -

This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.\n\nc) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise.

I have stripped off the power system specific code and put together what can effectively be used as a string extension for determining approximate equality between two strings. All of the algorithms used here have been pulled from online resources, translated into C#, and compiled into this library. I found several other similar open-source implementations around but nothing for .NET/C#. Adding the *.dll to your project will give you access to this extension and the individual extensions under the hood of the ApproximatelyEquals() extension.\n\n## Algorithms included in this project\n\n* Hamming Distance|http://en.wikipedia.org/wiki/Hamming_distance\n* Jaccard Distance|http://en.wikipedia.org/wiki/Jaccard_index\n* Jaro Distance|http://en.wikipedia.org/wiki/Jaro_distance\n* Jaro-Winkler Distance|http://en.wikipedia.org/wiki/Jaro_distance\n* Levenshtein Distance|http://en.wikipedia.org/wiki/Levenshtein_distance\n* Longest Common Subsequence|http://en.wikipedia.org/wiki/Longest_common_subsequence_problem\n* Longest Common Substring|http://en.wikipedia.org/wiki/Longest_common_substring\n* Overlap Coefficient|http://en.wikipedia.org/wiki/Overlap_coefficient\n* Ratcliff-Obershelp Similarity|http://www.morfoedro.it/doc.php?n=223&lang=en\n* Sorensen-Dice Distance|http://en.wikipedia.org/wiki/S%C3%B8rensen%E2%80%93Dice_coefficient\n* Tanimoto Coefficient|http://en.wikipedia.org/wiki/Tanimoto_coefficient#Tanimoto_coefficient_.28extended_Jaccard_coefficient.29\n\n## Approximate String Comparision\n> Note: This sample is taken from the [legacy documentation] on CodePlex.\n\nWhile all of the algorithms are exposed and can be used and can provide their raw results, they have been conveniently combined in a way that they can selectively be used to judge the approximate equality of two strings. This is done through the `ApproximatelyEquals` extension and by setting the desired `FuzzyStringComparisonOptions` and `FuzzyStringComparisonTolerance`.\n\nFor two strings that are desired to be compared approximately, a boolean response of equality can be garnered in the following way:\n\n\n```csharp\nstring source = \"kevin\";\nstring target = \"kevyn\";\n\nList options = new List();\n\n// Choose which algorithms should weigh in for the comparison\noptions.Add(FuzzyStringComparisonOptions.UseOverlapCoefficient);\noptions.Add(FuzzyStringComparisonOptions.UseLongestCommonSubsequence);\noptions.Add(FuzzyStringComparisonOptions.UseLongestCommonSubstring);\n\n// Choose the relative strength of the comparison - is it almost exactly equal? or is it just close?\nFuzzyStringComparisonTolerance tolerance = FuzzyStringTolerance.Strong;\n\n// Get a boolean determination of approximate equality\nbool result = source.ApproximatelyEquals(target, options, tolerance);\n```\n\n[legacy documentation]: http://fuzzystring.codeplex.com/wikipage?title=Using%20the%20ApproximatelyEquals%28%29%20Extension&referringTitle=Documentation\n\n" } ]
