Concept Maps of Crowdsourcing
Need-finding Results for Requestors
Identified here are our results from the observations presented above.
|to eliminate worker identity variability[D2,D3,D12,D15,D21...]
|it was a recurrent theme that they needed the right people. requestors consistently identified that skill sets and acceptance rates were criteria to gauge suitability of a worker to complete the task. It is getting the experienced engineer rather than a student. additionally, requestors need to be able to control the interaction of their tasks with workers. Turk granulates tasks and spread them wide, which might be great for some tasks. However workarounds were designed to get one person to complete a sizable task of greater than 10 questions. after qualifications, requestors need to be able to control their tasks by granularity, skill set, worker task preferences (so far). this is fundamentally different from qualifications only approach and can be partially coordinated with event logs.
|throughout many papers, it was identified that requestors go back to turk for the same type of tasks and thus need to be able to get the same kinds of results from the worker's process.
|need to have the ability to control the presentation of their work, by priority, sequence, preference, iterative, random, importance...[D11,D27,D23,D25,D31...]
|Requestors have gone to great lengths to customize the UI, workflows, qualification systems, etc. through code and APIs. And use the GUI for bulk acceptance and monitoring. This is only part of the answer, since much of the conflict is based from the restricted nature of the Turk interface.
|to control product variability [D1,D4,D8,E1,E2...]
|Creating form primitives and task primitives would help to streamline the more common tasks found on the system. Additionally, this will help to create controls where requestors put more work into the platform than it was designed for. Turk is intended for microtasks that can be completed in less than 60 seconds and not full blown psychological studies.
|need "some understanding of the system capabilities and constraints" [D26,D27,D29,D30,D31...]
|Requestors who choose a system for incompatible tasks leads to variability that affects workers. On one hand, the system did something right to get the requestor on the site, but not everything.
|need system flexibility to customize anonymity[D3,F2,F12,F20,G3...], pay [D13,F20,G2], information gathering[D11,D17,D23,D24,D27...], expand worker reach [D14,D29,F1,F3,F11...], task templates [F1,F4,F13], communication channels[E3,F14,F19,F20]...
|need to know if their task is there for pay or play[E5,F1,F16,D28,F17...]
|"Button hell" ---these words were expressed by a turker during the video interview. She has a certain task she performs and prefers, specifically tasks like essay or free form responses. For her the task is work and requestors who pay enough will get her to be involved in the project. Even though she enjoys a certain task, she expects requestors to pay the right amount if they choose to create a task for her. Gamers will do the same task for fun.
|"to motivate better, cheaper, and faster performance... without paying much"[D9,E4,E3,G1,H2...]
|need easy entry and exit out of the platform[D10,G,F2,F13,F14...]
|Download the .csv file quickly, upload the already typed questions into turk for implementation. This is the type of interaction and experience requestors want because they performed the work before they got on turk.
|to communicate with workers to clarify task design [E3,G1] and expectations [H6,I2,I4,I5]
Requestors should have a simple and efficient way of categorizing their tasks for easy understanding/access of workers [S10]
The requester needs a method to efficiently look out in the crowd and differentiate lazy turkers and eager beavers [C20, C21]
Requesters need a system to efficiently handle the appeals from the workers (L3, L10 of Workers)
Potential Needs for Requestors to Watch
- to communicate with another Requestor in some fashion [H8,] -> they need to define their own standards!
- the system needs to direct to other services in the business space that are more apt for the task at hand [I2]
- needs to pay into the work system [D7,E3,F18,] even if fair market rewards are unknown[H5] and they take a guess from known laws [I1,]
- need sponsorship to pay for turk work [I3]
- types of requester: researchers(open ? types, button types),quick and dirty [E2,E1,F14], spammers, ...
Need-finding Results for Workers
|need to be directed [T1,K,L,M9,P6...]
|The requestors design the tasks and the starting approach towards the workers. The workers only respond to the requestors.
|Need to be separated upon their intent with turk[N20]: gamers (Bored) [N3,N4,N9...], volunteers and workers [L8,L9,N4,M10,N21...]
|Not each turker views the platform as a market place. Throughout the readings, writers focused heavily upon the "worker" turker, whom has the most to gain/lose from joining the system. Otherwise, there are at least 3 types, which might be misidentified here: gamers, volunteers, and workers. Gamers are motivated to do tasks they enjoy or to solve boredom. Volunteers do it to help out requestors of non-profit agencies and do it altruistically.
|need to eliminate task (process) type variability [T2, K,L4,M8,N10,N11...]
need reproducability [T2,M10,N11,N13,N14...]
|need to eliminate requestor variability [T2,K,L4,P7,O3...]
|Too many different approaches to the same task creates headaches. In the world there are so many to choose from and requestors should not be recreating this wheel. industry style guides have been around since... forever. 
|need bulk acceptance of multiple tasks [T3,K,L4,L13,O1...]
|need standardization of tasks to be able to scale up to viable living incomes[T2,N13,N14,N15,O2...]
|need granulification with permission from the requestor of tasks to be able to scale up to viable living incomes[T2,N13,N14,N15,O2...]
|This will help with the low professional earnings from turk. As one example, If a requestor sought and paid for a standardized form task that followed a model like tinder, whereby only a question and yes/no box were presented in the screen to the worker and then repeated, the worker can easily and rapidly complete turker type tasks without doing work above and beyond the task itself. Thereby reducing the questions and schemes they have to do prior to earning an income. Of course, this design is not that simple to just execute.
|need well designed scheduling theory based algorithm support if they turk for work[T2,T3,P38,P47,P51...]
|The turkers do this as they have multiple windows and inventories of tasks on their screen. Why not use the stuff from the field who has solved their problems before?
|need to feel safe from negative experiences[K1,L1,L7,N7,P5...]
|need a library of work primitives to support task design from requestors[K3,K4,K,L,M4...]
|Work primitives are the building blocks of repetitive tasks. Let's face it. Turk requestors seem to keep doing the same types of work...
|need to rely on strategies to select HITS[L10,L11,L12,R1,Q3...]
|need to be able to remedy errors [N6,P2] arising from miscommunication[L1], rejections[L9,L10,P2]
need to communicate with other workers in forums[N7,N1,P10,P9,Q...]
|need to be able to provide their own self governance[N3,N1,P10,P9,Q4...]
|Turkers have already done the work publicly. Software can improve what they have already done.
Potential Needs for Workers to Watch
- need to communicate requestor patterns with others that work against professional worker's intent[L1,P10,P5,R3]
- need the ability to control privacy rights and access[P10,P9, R2]
- need accessible alerts of changes in the system and how it affects them - kept simple![Q6]
- need filters to eliminate spam tasks[P5]
Observations about Requestors
A. Video Interviews.
There are different reasons people come to crowdsourcing for:
- income – housewives, workers who want to make extra money, free lancers
- getting work done – large companies, business personals and other personal works
The current crowdsourcing platforms are not fully satisfying the requirements of the requesters and also the workers.
- To manage and better understand how to get more money efficiently, there are worker forums, similarly there are requester forums to help requesters in various areas in the platform.
- There are communities such as "Turker Nation" which help workers get more qualitative work
- There are many people who are entirely dependent on such crowdsourcing platforms for their income and this is their only source.
- Even after usage of the platform for a certain time, the factors are not clear to some workers and take help from forums
- to better understand the platform
- teach requesters about Master's qualification
- Share the hits and such other tasks
- When the requester is accessible for clarification, the workers mostly provide feedback through mail on what clarification is needed and how should they refine the task
- Some workers were cheating in tasks so, the requester then added qualification to the task to filter out people who might possibly cheat.
- Engaging the workers is a difficult task for the requester
- Sometimes the message are not in English which is difficult to reply.
- When there are huge number of tasks posted on MTurk, it becomes very difficult to answer all the enquiries and so, the requesters hire people to answer queries and manage other requester works
- Sometimes study specific grousp to take advantage of worker productivity.
- Sometimes the built in templates to create tasks are not customizable - making it a difficult process to reproduce the whole template manually for a small change.
- There is still a generic way to be generated on the hourly rate to be paid for the worker
- New requesters are inclined to reject a slightly off work with the excitement of using their ability to reject
- Keywords - anonymous, complicated, tricky, tiring
B. Ipierotis, P (2010)

- For a long term user, this kind of additional personalized interface works, but not for short term users
- Requestors cannot easily differentiate good workers from bad workers
- Getting the task done by multiple uninterested workers and getting the quality check done is a huge frustration and a waste of time for the user
- User wants to get these questions verified
- Does the worker have the proper English writing skills?
- Can the worker proofread?
- Want to provide rating without cognitive load.
- Requestor is the most affected guy in MTurk unlike the sellers in amazon.com
- Rating must be given from the side which is getting affected.
- Requesters might have an idea or not have an idea of the time required to complete the task
C. Bernstein, M. & et al. (2010).
- Make grammatical mistakes while writing
- Find it huge to correct a tense change
- Find it difficult to trim the size of the written paragraph
- Find it difficult to explain the task to workers
- Commonly make spelling mistakes
- Take help from friends and people they know to proof read or reduce the article size
- Expects further help in complex tasks
- Expects text correction delay time to be less – prefers real time
- Is concerned about the task and content privacy
- Wants an interface which is understandable and helps him progress
- Waits for the correction to be clearly differentiable from the original data
- Looks out for what part of the sentence has been compressed and which part has been expanded
- Looks out for people who can complete the task on time – get things in limited pages and within the deadline
- Is concerned and wants to confirm if the worker has understood the task – wants to confirm
- wants the control in his hands to accept the corrections or not
- Wants to notify only the change required in certain pages or paragraphs
- Finds it difficult to express the correction method correctly to the computer in case of scripting.
- Finds it difficult sometimes even to express to workers on what correction is to be done
- wants to decide on how many people should work on his content
- Wants to avoid lazy turkers waste his time
- Similarly wants to avoid Eager Beavers as they complicate the task for him
- Wants to keep a check on if the workers are motivated enough while working

J. Video Interviews.
- Choosing a task is always done keeping in mind the worker's rating
- The rating should not go below 99
- They wait to see if the requester is paying for the hits or is ignoring their work
- If the requester pays promptly or provides feedback promptly, then the worker is happy to work further knowing that the requester is a good work provider
- If the requester doesn't have a rating, the workers mail the requesters and if the requester replies promptly to the mails, then again it confirms that the requester is reliable.
- Another confirmation which the workers get when they receive a mail from the requester is that, they can now have a discussion if with their requester if their work is rejected and know why it has been rejected.
- Some users want to make the best of time and focus on keyboard shortcuts to perform better and faster.
- Some times there are automatic quality controlscripts which might or might not give accurate results.
