Would like to create and algorithm that describes feelings about certain songs. It doesn't have to be overly complex. For example, I need 10,000 postings similar to the following but obviously different: I really like this song, every time I hear it I cry. This is the most amazing song ever. If you don't like this song something is wrong with you. Amazing.

I would like to analyze text collected from online job postings to identify trends--changes in skills requested or types of tasks or problems being addressed in the posted jobs. Approach: Detect changes in keyword frequencies in job postings. I'm interested in both single keywords and bi-grams for the initial phase of the project. Specifically, we want to detect when large (either by percentage or by total frequency) changes in keywords occur month by month and quarter by quarter. Data Source: To be provided. Sample data provided in Excel. There will be on the order of 25K job posting records per calendar quarter. There will be 3-4 years' of data. Deliverables: A database that includes a means of identifying large changes in keywords in the job descriptions. Bulk boilerplate language from the job descriptions should be automatically cleansed to improve analysis. (e.g. Remove text such as "When you choose KPMG as the place to build your career in tax, you can really add value...

I'm working on a courier service and I would like my clients to add their shipments in my database directly from their systems using a simple API. The basic functionality of this API should be: * Posting shipments to my database; the response would be a confirmation number * Deleting these shipments from the database in case the client changed his/her mind. * tracking their shipment based in the confirmation number they received, I wrote all of my code in php so preferably I have a solution which is also in php unless you propose a better solution.

Hi, I am developing a research project and I need somebody to find, organize and do some basic calculations. The job is the following: I have a dataset of 5,194 countries with their corresponding years. I need you to find the following information: total (i.e., official plus friendlies) number of soccer (football) games played by those countries for those years with their number of victories, losses and draws. Furthermore, do the same only for the friendly games. I have found a website which seems to convey all the information, so this is not a difficult task. However, as we have a lot of observations, I will favor applicants with programming skills who can develop a simple code to scrape the data and speed up the process. Please, get in touch if you are interested. Best, Decima Technologies

Hello, I would need the following. I have remote sensing images in netcdf or Geotiff format with lattitute and loongitud layers. I would need to open them, treat them and save the new layers in the same format. I need an r script to re-grid the images to different sizes of pixels. For example, if my image has a 30 m resolution I would need to expand it (using interpolations), to 60m,100m,250m,500m, 1km and 3.5 km. Then I would also like to be able to do the oposite, take a 250m image and create a finer grid, to 30m resolution. I would like to compare images provided by different satellites with different resolutions but for this, I need them to be at the same scale. I know in IDL is the function CONGRID but I need it to be in r. is it possible?

We are looking to obtain detailed reviews and feedback on individuals and companies that carry out all types of vehicle repairs and maintenance. From servicing a car and replacing brakes to wheel refurbishment and re sprays. Any type of work carried out to a car. We need the reviews to come from previous customers and we need to be able to have access to all this data which will then be on our website. This data can be worldwide and needs to be detailed to include type of work, where it was done, value for money, customer service, rating etc. it will need to be linked to the individual/company that carried out the work. Looking to potentially obtain millions of reviews so could be an ongoing project.

I need a simple web interface for input/output of time series data that is then fit to a dependent variable series via multiple linear regression (MLR) in R using various model selection algorithms (forward, backward, sequential, etc.). The data will consist of a time series of roughly 20 periods (this can vary from ~12 to ~40) and anywhere from ~80 to ~1,000 independent variables. MLR models will be limited to 15 regressors + intercept. For each set of regressors I would want the top ten models (i.e. top ten models for 15 regressors + intercept, top ten models for 14 regressors + intercept, top ten models for 13 regressors + intercept, etc.). Additionally, certain regressors may be identified as "necessary" beforehand and must then be present in all models. Descriptive statistics will include R2; adjusted R2; standard error; AIC; and BIC. Time Series Partitioning: for each set of data, the entire process needs to be run on several in-sample/out-of-sample partitions. For exa...

There is a popular app with large amounts of data that we need scraped I need a scraper built that will do the following 1 - Emulate IOS/Android (i am assuming Android is easier?) 2 - Rotate though different IP's/locations as needed. 3 - Create and add new accounts - these usually have to be linked to a social account so you will need to start there. This App sometimes uses a phone number verification so I can provide you with some prepaid SIM #'s though easier if you can handle it all turnkey. Hopefully we will not need too many accounts 4 - mimic user behavior to have the app display the data needed. 5 - setup scripts to run the bot and organize the data based on different variables I would hope that the right candidate already has most of this framework already built so we can just plug and play. Terms and price flexible, most important is communication abilities and ability to collaborate to find solutions as we do NOT expect this to be a straight forward datamine If...
