I use regular expressions (regex) a lot in my NLP projects. There is a bastardization of regex called spintax. It is basically just {content|other content} chained to other {alternatives|strings}. It usually comes nested as well. so it could be {phrases|some {other|similar} content} chained to similar {alternative {synonyms|strings}|parts of speach} In real life, it looks like this: "{{I need|I want|I would like} |}{help|support|assistance|help support|{customer support|customer care|customer service|support service|support services|consumer support|client care|client service|service}}{ {please|if possible|if you please|bear in mind|pls}|}" This outputs variations of the sentence such as: - I want help if possible - I need support please - I want help if you please - I need assistance I need a function where I can just paste this spintax code into a variable and have it spit out these variations. I imagine it could be something like: spinTax = "{{I need|I want|I would like} |}{help|support|assistance|help support|{customer support|customer care|customer service|support service|support services|consumer support|client care|client service|service}}{ {please|if possible|if you please|bear in mind|pls}|}"; variationCount = 4; spinFunc = (*Some cool function that spits out variations*) spinClean = Union[spinFunc]; (*Clean up the list, remove duplicates, etc. Run function again until desired count of unique variations is reached*) Out[10] = {"I want help if possible", "I need support please", "I want help if you please", "I need assistance"} Here is my code in PHP that outputs in json. Maybe this can help. # Show results. if($output['success']=='true'){ class Spintax { public function process($text) { return preg_replace_callback( '/\{(((?>[^\{\}]+)|(?R))*)\}/x', array($this, 'replace'), $text ); } public function replace($text) { $text = $this->process($text[1]); $parts = explode('|', $text); return $parts[array_rand($parts)]; } } $spintax = new Spintax(); $string = $output['output']; $spunVariations = array(); for ($x = 0; $x <= $variationCount; $x++) { $spunVariations[] = $spintax->process($string); } $spunVariations= array_keys(array_count_values($spunVariations)); $x = count($spunVariations, COUNT_RECURSIVE); $spunVariations= array_keys(array_count_values($spunVariations)); $arr = $output['output']; //echo json_encode($arr); echo json_encode($spunVariations); } else{ echo json_encode("Error:". $output[error]); } } else{ # There were errors. echo json_encode("Error:". $output[error]); } This PHP example doesn't have the function of ensuring that the resulting list has only unique values in it. It also doesn't have any checks to make sure the resulting sentences are greatly different from each other. David Johnston 2016-10-14T07:18:28Z https://community.wolfram.com/groups/-/m/t/796831 [Martin Hadley][1] and I are organizing a 5-day Wolfram Language workshop at Oxford’s [Digital Humanities Summer School][2] “Analysing Humanities Data: An Introduction to Knowledge-Based Computing with the Wolfram Language”. Here’s a brief overview from the course description: > This example-led workshop will provide a comprehensive introduction to techniques for analysing a wide range of humanities data with the Wolfram Language; from text analysis, image processing, and visualization, to network analysis, time-related and geographic computation, and machine learning. The course assumes no prior knowledge of any programming language. Participants will learn the concepts needed to import, manipulate, and analyse humanities data using both the natural-language input and scripted interfaces to the Wolfram Language and to share their data and applications in the cloud. Part of the material in the course will be drawn from William Turkel’s open-access textbook, *[Digital Research Methods with Mathematica][3]*  We’re looking for one or two experienced WL users who would be interested in coming to Oxford between July 4th and 8th (at our expense, naturally) to give a c. 3/4 or hour long presentation/talk on some aspect of the WL relevant to the humanities. This need not be text related! Yes, we do more than just read old books :^) Potential topics for your presentation might include geodata & geocomputation, network analysis, general graphing & plotting, time series analysis, an intro. to machine learning, sound analysis & sonification, using MMA with R-Link… etc. Martin (who is a data scientist for Oxford University IT Services, and previously worked as a consultant for Wolfram Research,([https://uk.linkedin.com/in/martinjohnhadley][4]) will be teaching the course. My research background is in the humanities (I’m digital project manager for [http://culturesofknowledge.org][5]) and I am still a WL beginner, so I'm collaborating with Martin to make our examples and data as relevant as possible to our predominantly 'newbie' humanities/social sciences audience. If you’re at all interested or curious to learn more, please let us know sooner rather than later, as we’d like to firm up the syllabus quite soon. We can host you for one or two nights in Oxford (including travel) if you’d like to give one presentation, or for as long as 5 days if you’d like to stay longer and give two talks (or perhaps even assist us with running the class itself). Although we didn’t plan this, this is a particularly auspicious time to be learning the WL for the first time, with lots of new resources newly available from WR and elsewhere, and huge potential for applying it in the humanities.

From what I can see there are two options for us to get more out of these cards, both of which are incredibly time-consuming and not worth the effort without the process being automated. I'm hoping someone here can help direct me towards a solution for either option that I'll detail below. 1. Often times the cards are purchased in large lots where boxes may contain cards primarily from the same year/set, i.e. 10,000 2012 Topps baseball cards, 20,000 2015 Upper Deck baseball cards, etc. The idea would be to take cards from various sources and shuffle them in a way that there is little or no consecutive duplication, basically creating "grab bags" of X number of cards per package. Think of shuffling 10 decks of playing cards simultaneously then dealing 10-card "hands" that are individually packaged. The trick is making sure those 10-card hands have a variety of cards instead of all from the same set. 2. This one is much more difficult but I can't imagine it wouldn't be possible given advances in OCR technology...same as option #1 but have the cards sorted by teams and then randomized. Potential issue is handling/shuffling of the cards as they can't be damaged, so that needs to be addressed in any possible solution. Any ideas feel free to contact me directly, whether individual engineer or corporate. abc def 2015-05-19T22:38:20Z https://community.wolfram.com/groups/-/m/t/2159329 Hi there folks, I'm new to programming and to Wolfram. I'm looking for some tutoring to get up and running using the Wolfram language generally, but also in Jupyter notebooks (ideally for rudimentary applications in data science). Sessions over zoom, or similar. To restate; the main thing I would need from a prospective tutor would be good knowledge of how to run the language from Python/Jupyter. And English speaking. Cheers, Mike mike douglas 2021-01-11T15:27:57Z https://community.wolfram.com/groups/-/m/t/2931798 My objective is to convert a 1970s published paper -- "[Inferential statistical methods for estimating and comparing cosinor parameters][1]" into a Mathematica notebook ... that is as close as possible to the original paper format *and* is computationally live, meaning it is possible for those who download the notebook to change input data, tweak implementations, etc and see the results. A follow-on project is to publish sub-segments of the methods to Wolfram's Function Repository. I am seeking a mentor to guide me with the initial part of the conversion for Section 1 of the paper -- so that I may learn by example and continue on to complete the conversion of the remainder of the work. At the conclusion, I'd like to meet again to review the entire Mathematica document from top to bottom to ensure it is a faithful recreation of the original paper. This is entirely a self-funded project -- I have a very modest and humble budget. If interested, please send me an example of a Mathematica notebook you've published that would be "similar" to the format of the cited paper (above) -- and let me know of your consulting rate and availability to partner with me for 10 hours of work (with some zoom based paired Mathematica programming) to translate Section 1 of the paper into a Mathematica notebook. NOTE: I don't know that 10 hours is too much or too little, but I do recognize your time is valuable and that 10 hours of undivided attention is helpful to gain momentum on the work.

I'm a teacher of journalism at the international EDJ school in Nice FR My students have access to Mathematica 14 (but they mainly use chat-driven notebooks as the wolfram language is sort of complicated to them). Anyway. As part of the "Data Journalism" course I want to give them the assignment to read this article https://www.dailymail.co.uk/news/article-13266707/Everyone-Japan-called-Sato-year-2531-countrys-marriage-laws.html It tells the story of a Tohoku University economics professor that concluded that, given how married couples in jpn drop one of their family names in favour of both individuals taking the same one everyone will be called "SATO" by 2531. I'd like the students to perform the same simulation for their own country (after finding out the candidate family name -- for Italy that would probably be "Rossi") Now, after some digging I've found in this PDF https://think-name.jp/assets/pdf/Sato_estimation_yoshida_hiroshi.pdf the method used to perform the calculation for Japan: Handling of Past Data First, we obtained the number of people with the Sato surname in Japan from the data provided and published by "Myoji-yurai.net" (https://myoji-yurai.net/), which covers more than 99.04% of Japanese surnames. Next, we divided the number of people with the Sato surname by the total population of Japan for each year (estimated by the Ministry of Internal Affairs and Communications) * 99.04% to obtain the "ratio of the Sato surname in a given year t": x(t). From the change in the Sato surname between the latest years of 2022 and 2023, we calculated the one-year growth rate \[Rho] in the Sato surname ratio. Estimation Results (1) Growth Rate \[Rho] of the Sato Surname It is found that the ratio of the Sato surname x(t) increased from 1.480% in 2013 to 1.530% in 2023, an increase of 0.05 percentage points over more than 10 years. Calculating from the data for the most recent points of 2022 and 2023, the growth rate \[Rho] of the Sato surname ratio is (1+\[Rho]) = 1.0083. (2) Future Simulation Assuming that the ratio of the Sato surname to the Japanese population will grow at a rate of 1.0083 each year, starting from 1.530% as of March 2023, and repeating the calculation of x(t+1) = (1+\[Rho]) x(t), it was calculated that the ratio will reach 100% in approximately 500 years, in 2531. ----- **And the question is : Is anyone kind enough to write me the Wolfram Language generic code to perform the same** ? Ideally, students could get their own country basic data (if possible directly with WolfrmaLanguage functions, if not possible from outside sources) and have the system perform the simulation for them (of course, forcing the Japanese role "select one family name" even if not the case for the specific country) It is also possible that it will not converge and we will never have a "Rossi only" country not even in year 3500...or maybe yes. But that's also the point of the simulation. Thanks!!

John Remillard 2020-11-09T05:57:28Z https://community.wolfram.com/groups/-/m/t/3644908 **TL;DR** I'm looking for someone to refactor a Mathematica notebook I've got from a fellow researcher so I can use it as a reliable reference implementation. I expect it's a few hours of work for the right person. I can offer financial compensation and/or my own technical expertise. Hello Wolfram community! I hope this is the right place for this kind of request. If not, my apologies! I'm a PhD student in the final stage of my project, an attempt at closed-loop control of water jets from firefighting robots using UAV imagery as feedback. The controller design is based on the Smith predictor architecture, which requires a predictive model to compensate for the long dead time of the system. Accurately predicting the trajectory of water jets is far from trivial. One of the most promising models I could find is described in https://link.springer.com/article/10.1007/s10694-021-01175-1. The model is formulated as a system of ordinary differential equations. I tried implementing it in Python so I can integrate it with my other components. It's almost complete, but despite several months of debugging I haven't been able to resolve the remaining issues. So I contacted the corresponding author. They confirmed some errors I found in the printed versions of the equations, and kindly provided their original Mathematica implementation. This helped, but my own implementation is still incomplete. The issues could stem from additional errors in the printed equations I/we haven't found yet, mistakes in my implementation, or differences in solver behavior (Mathematica's vs. SciPy's solve_ivp() function). Unfortunately, the notebook is hard for me to follow and differs quite a bit from the published paper (structure, variable naming, angle conventions, etc.). I've never worked with Mathematica and don't have the time nor patience to properly learn it before my deadline. The author is currently unable to provide further support, but since I'm getting more and more desperate to finish this subproject, I'm now seeking third-party help. I'm looking for someone to refactor the notebook into a clean, well-structured reference implementation. Specifically, I'd like them to - remove unused and redundant code (many expressions are duplicated) - improve structure - improve documentation - add small quality-of-life improvements if appropriate - flag any noticeable discrepancies The refactored version must reproduce the original results, in particular the figures shown in the paper. Ideally, it should make it easy to experiment with the equations and parameters. One specific goal is to verify whether the rearranged equation forms I use in Python (to match SciPy's solver interface) produce the same results as the original formulation. If you're interested, I'll obtain the author's permission and share the notebook privately so you can assess the scope before we discuss compensation. Bonus points if you have experience with physics-based simulations and are open to occasional follow-up questions :) Many thanks and regards!

Regards Sinval Sinval Santos 2019-09-21T12:42:37Z https://community.wolfram.com/groups/-/m/t/2266597 Hello! I am hiring for a full time Computational Chemistry for one of my companies, SmarterSorting. Very much a WolframLang, WolframAlpha opportunity. Company is based in Austin, TX, but this role can work anywhere. If you love Wolfram, chemistry, computational thinking and fast growing startups that have lots of fun data, apply or message me. https://boards.greenhouse.io/smartersorting/jobs/4005347004&dep=4004121004 Russell Foltz-Smith 2021-05-12T14:09:51Z https://community.wolfram.com/groups/-/m/t/1703796 Consulting is needed for small sized company providing actuarial and data science consulting services to insurance companies in the GCC and Pakistan. The company has an old code base which is written in Wolfram language by a former employee. The primary role is to do ETL data to an SQL Server. The data cleaning and transformation is performed in Wolfram language and then loaded into SQL Server using "DatabaseLink`". The code also perform several analysis tasks by automating the generation of some very large queries in SQL and visualization. The queries are generated in Wolfram language then send to SQL Server for execution and results returned back and analysed. The code seems to be working correctly but the company's client has recently changed the data structure and thus the code requires modification to work again. Unfortunately there is no one currently on the company's team with sufficient Wolfram language expertise. The code base contains few pages of Wolfram language code together with dynamic SQL mixed. In addition, there are several StringExpression and RegularExpression in the ETL portion of the code. The company is looking for a temporary consultant with Wolfram language and SQL expertise that can help them modify the code to make it work on the current dataset. The consultant will have the necessary expertise to move the company from this temporary phase of disruption. If anyone is interested please reply back on my email. Please state how much will you charge for the service? The company doesn't need a full code rewrite but somebody to understand the code and make necessary changes to make it work on the new dataset. Do you have consultants who can be available in Pakistan (preferable) or UAE to provide the service on site? Also what will be the difference in charges if the company go for remote consulting instead of on site. Will you charge on hourly bases or lump sum for the project? You can answer privately on my email: xxx Muhammad Ali 2019-06-13T03:47:16Z https://community.wolfram.com/groups/-/m/t/1575766 I'd like to build a framework, where self-growing simulations can be done on a checkerboard that allows for element sizes different from 1. Been building it for 1 month now (more visually oriented guy here), but the complexity of the algorythms I come up with always gets to me. I'd like it to work in Mathematica Home Desktop. I own a license. Abilities to set are: size of the board, list of different sizes of elements to use. The elements should be placed such that they only touch corners and never overlap. It has proven so hard for me to come up with an elegant and fast, scaleable approach that I would welcome any hints or aid. I have a brute-force solution that does what I want I can share on request. Hope you find the time to write back and see if we can cook something up. All the best, Mark Mark Florquin 2018-12-20T15:35:52Z https://community.wolfram.com/groups/-/m/t/1266493 Hi all -- I'm looking to connect with some Wolfram language power-users located near the following areas: - Charleston, SC - Atlanta, GA - Washington, DC - Raleigh, NC - Baltimore, MD - Chicago, IL I work with our Commercial team to establish and support licensing in these major cities, and I think it'd be really beneficial to work with some of our more passionate users there. Obviously, being located in Champaign, I have some limitations to my knowledge of as well as my access to these areas, so I think collaborating with you all to either get a better idea of the tech landscape or even working to raise awareness could be a worthwhile effort. Curious in connecting to some of you. Any level of interest from "I can help you learn more about this city's tech landscape and its networking opportunites" to "here's some connections I have in the area" to "let ME be your Wolfram Language evangelist for my city" is appreciated. Feel free to comment on here or shoot me a quick email at samt@wolfram.com if you're interested. Excited to connect! Sam Tone 2018-01-16T23:31:20Z
