Essay Grading


What is lsa
What is LSA?

LSA learns the relationships between text documents and their constituent words (terms) when trained on very large numbers of background texts (thousands to millions)

Each term, document, or new combination of terms (new document) is represented as a 300 dimensional vector of numbers

LSA learns how to group documents and terms that are similar in a “Semantic Space”

Documents can be domain knowledge, writing samples, e-mail files, course materials, job and training historical records, etc.

LSA judgments of similarity agree well with human judgments


What lsa is not
What LSA IS NOT

NOT Simple KEYWORD Matching

Studies have shown that:

  • People will agree on the Keywords to characterize a text only 15% of the time

  • If you have 100 people name a document (e.g. a recipe or computer command), you will get 30 different answers

    LSA operates on the deep level (Latent) meaning of words rather than the surface characteristics (exact matches)

    Example:

  • The doctor operates on the patient.

  • The physician is in surgery.

    These sentences have no keyword overlap, though you understand that they have very similar meaning

    KeywordLSA

  • Doctor—Doctor 1.0 1.0

  • Doctor—Physician 0.0 0.8

  • Doctor—Surgeon 0.0 0.7

  • There were 520 student essays total.

  • For a reader to detect the plagiarism 134,940 essay-to-essay comparisons would have to be made.

  • In this case, both essays were scored by the same reader and the plagiarism went undetected.
