    This Freelance is very smart and capable. But beware! He is a blatant liar! Before explaining I have skype screenshots to prove (he will fabricate new stories like usual) He made the bot, but originally promised he would fix bugs and small issues-he said he would be available for upkeep, the moment he was payed HE WAS GONE! no replies for a few weeks, then he wakes up and says he will do, the gone again! He had the audacity to bid again on the same project, when I posted it again for someone to fix what He promised he would do. Punchline-He's not trustworthy at all!

    Hello,I need someone who have experience with scraping data from web service/API help me with this work. If you are student, do not apply. I need professional people who have experience with python scraping that can finish it for me. Knowledge of visualization will helpful for bonus. Here is the job. We have a website with web service call like a survey interview, depend on the previous question, it will display the next question. So I need to get all the content of the survey.The first request to the server is something like:http://localhost/?s=Start&description=DES1&value=VAL1&units=UNIT&description=DES2&value=VAL2&description=DES3&value=VAL3It will create a session variable for current session to use in the 2nd request as well as return the first content (next question). Then there will be a series of questions for this above session with value Yes, No, Back (first question don"t have Back) call with the URL like below:http://localhost/?m=NAME&session=530cc4c3000082aafmd&navigationMethod=[Yes, No, Back]Each time we click Yes/No/Back button, the navigationMethod variable will change accordingly and return a json content for the next question:{"variable":{"variable1": "value1","variable2": "value2","variable3": "value3","variable4": "value4","variable5": "value5","variable6": "value6","variable7": "value7"}}At the end, there will be no question, just a json return with a lot of information. But now, the session variable is killed so we can not get back to previous question.What I need you to do is to write a python script that can help me to scrap all the data and save to a text file. What I think we need to do is write a breadth-first search or depth-first search function to traverse along the tree that can save each state when we click the button. The state will include both the hierarchy of current node (like 1.2.1.1.1.2.1 ... [1 for Yes, 2 for No]) as well as the content (json returnted). And then when the session variable no longer work, we will need to create a new session variable and get the previous state we have saved and continue, continue until we traverse all the leaves of tree.Below is requirements:+ It should be a function that I can call from command line like:CMD >>>> python function_name.py -DES1 -VAL1 -UNIT1 -DES2 -VAL2 -DES3 -VAL3 -output.txt+ The content of text file should have some way that allow me to track the hierachy of questions, which one display first, which one is second, which one is the child of which one. [Because it limit to 4000 character, I put the sample in text file.]The deep of each tree may be up to 50 levels, even more than that. Bonus 1: If you can have some way that allow me to filter the content it return, like I only want to save variable3, variable5, variable6 from the json return to text file. There is a bonus for it.Bonus 2: If you can format the data and write a tool allow me to import the text file output.txt and display it like a tree diagram like this example http://bl.ocks.org/robschmuecker/7880033 , whenever I click to one note, i can get the data popup, that would be great. There is an extra bonus.Bonus 3: If you can write a tree diagram allow me to load the text file output.txt and make change, and save it back to the original file. There is also another extra bonus.Let me know with your price:Basic: XX$Bonus 1: XX$Bonus 2: XX$Bonus 3: XX$

    2 Things.1. Create a client portal in my wordpress site.2. Integrate an api into the client portal.The thought process: A company goes to my site and has the ability to run several reports for free using the api. The key for me is to get them to sign in so I can retain their email address and they can save/download the data from the api. On one page, I would like there to be a button that says "enter domain name" and the api will connect with the third party software and have the data flash on my web page (in a report format). They can then choose to login and save the report or download a pdf version of it.Hopefully this made sense.

Ideally the function will get the match code (you can see it in URL after /match/[match-code]/) as a parameter and the interval in seconds to update, and return an array with all the real time statistics mentioned above. The parsing should not take more than 5 seconds.

    I need to scrape the prices off of 5-8 competitor"s eCommerce sites. I will need the product name, price, and sku. The data would go into a MySQL DB with an available field we could pair the individual products with our product sku. We can a run report and get a price comparison in CSV for the lowest price for a given product. No elaborate user interface needed. We are fine using PHPmyAdmin to pair the products to our sku manually. This is something we will run once a week or more.Once this is complete we would consider using BigCCommerce"s API to automate the price change in our store, or at least format the csv with the needed fields for importing and updating product prices.www.midwestsupplies.com would be an example of one of the site to be scraped.Thanks!

    Hello there, I have a java project which I want to develop for my report. The project is simple WebCrawler with no interface included. I have managed to finish most of the parts. All I want is optimisation and changing some features of the project. The reason I want to hire a person is, I have no time to optimise this project for the following 1-3 months. What I want is;1st) The database kept on text file. I want to change it into MySQL database to make it more efficient and easy to understand. 2nd) Threads. I am using threads but I want them to work more efficient than current version. What threads will be doing is, they will be assigning to one job only ( for example; Start crawling: X.com, dont pick any other job like Y.com, Z.com until it finishes the X.com ). The trick point is, when the thread is crawling the links in X.com, it should check the links in the another database ( pool DB for links ) whether it exists or not. If it exists, it shouldnt add it into database to prevent extra work and prevent repeated data.3rd) I want this code to run properly. It doesn"t work efficient currently there are some stucking points and other stuff. I have been using several testing tools but some internal code should be corrected. 4th) I am using GeoIP.dat file, update it with the never version. ( Pretty simple.. )----Finally;I will be giving the whole source-code to you. You will have plenty of time to understand and achieve the goals stated above. As I am giving the source code to you, you would keep it and use it in the future, so please consider this before offering a price. The codes, other stuff and information will be updated as soon as I hire the professional.The due date is : May 20th 2014 (±5 days)Thanks in advance!

    We are seeking someone who is familiar with the Amazon seller marketplace, EBay seller marketplace and Microsoft Excel. Also having knowledge of TV Shows, Movies, Video Games and other entertainment products would be helpful. You must be as consistent as possible and able to work in a timely manner.Task: You will be given a .xlsx excel file with a list of products that are listed on Amazon with blank columns that have the specific details. The top of the file shows various examples of how the different fields should be filled out with acceptable answers for each cell to use as reference. Most of the information can be found within the Amazon listing but some might require best judgement if the listing on Amazon does not have the information.Main File (needs to be filled out)- Product Attributes.xlsx- Attached is a sample file of how the sheet will look and blanks that need to be filled out. You will be given limited access to view these products to fill out the blank cells. There are more items that need to be filled out than what is on this list. Assistance File- (can be used to help)- amazon_attributes.xls - Attached is a file that can be used to help fill out the information. This file is only used for purposes to fill out the product attributes file. The product description and title may contain useful information to aide in creating and might be used to pull detailed information.Cell Description *All cells have a 50 character limit max*:Product Attribute:Brand - The main media category that the product will fall under. If it is a TV Show or movie, the title will be appropriate. Product Attribute:Size - Based on the sku of the product (sku= product001-S would be filled out as Small). If it doesn"t have a size, the size would be one size. Some products have multiple sizes. The range of sizes would be filled in for size in this case (Small-2XL). Please be consistent with the sizes regarding cases and short hand (do not write, Small for one product, small for another, and s for another).Product Attribute:Size Type - Primarily for shirts. Most products are either regular size, juniors or youth. This is primarily for clothing products only. Product Attribute:Color - The main color of the product.

Product Attribute:Theme- Key words that can be used that can tell more about the product and used for better search results that relate to the theme of the product. If it the item is a Wonder Woman t-shirt, acceptable answers could be DC Comics Superhero Heroine Super Hero. Product Attribute:Gender - Mens, Womens, Baby, Boys, Girls, Infant/Toddler, Adult, Children.

Some products take up 1 row while some products that have different sizes takes up 4-7 rows. There should could be roughly 15K-20K rows which would make 2K-4K different products.

If not, delete them. - check if on the dealer website there are products that are not on my website. If yes, add them (i wil show you how) on my website.The work is very easy. You have only to make a simple research by code on our website and check if on the dealer website is still there.You can use automatic tool if works properly.More information if you ask me. Thanks.
