Annotations
Have a link from the DataShop to the Theory Wiki (Dataset to Project Page)
- Michael Bett, ET Mtg 11/14/2007
- From meeting minutes:
- Michael: Link the dataset to the project page? In the pipeline have a clickable link to the project page (make project name clickable).
- Brett: Link to a dataset directly? Is that obvious to users? Click on dataset link -> log in -> redirected back to dataset.
Annotations on transaction level
- Ryan, ET Mtg 12/5/2007
- Has models which can annotate something like: gaming, bored, etc.
Annotations on the student level
- Ido Roll, Interview with Brett Leber, 1/19/2009
- Can annotate on student level, a percentage the student is gaming
- Ido has mentioned annotations on the student level
Dataset Discussion - Capture data-integrity issues
- Ken Koedinger, Team Meeting, 8/15/2009
- As a stakeholder in the DataShop project, I want to capture and publicize the data-integrity issues discovered with data sets so that data is better documented (and so we've fulfilled a promise to our funders to better document data).
- As a user of DataShop, I want to discuss datasets and have that discussion attached to the dataset so that others can comment and better understand any data-integrity issues I've found.
Linking to internal pages
- Alida, 10/18/2007
- It would be handy if a link can be saved to any dataset, sample, page in the DataShop.
- Currently, https://pslc-qa.andrew.cmu.edu/datashop/DatasetInfo?datasetId=793 works if you are already logged in.

Automatic Distillation
- Ryan, Summer 2008, Startup Memo
- As an educational data miner wishing to develop a machine learned model with PSLC data, I would like to be able to automatically distill data features (e.g. custom fields) commonly used in past educational data mining research for a new data set (see, for instance, Baker, Corbett, Roll, & Koedinger, 2008 in UMUAI)
- Could be implemented as a plug-in

Analyses by LearnLab
- Organize data by LearnLab, not by "data set" [Ryan, Aug 2008; Bob, Sep 2008; Maxine, Sep 2008]
- Essentially, current data sets become samples, but the top-level unit is the LearnLab. You can take every data set in a LearnLab together as a sample.
- Implies being able to run analyses across data sets, and export multiple data sets together; to create multi-data set samples
- As a user of DataShop, I would like to look at learning curves for all Algebra data together (for example), or export all Algebra data
- Important long-term, but is a lot of work -- in particular, we need to solve scalability issues first
