A solution to Plato's problem: The latent semantic analysis theory of acquisition, induction, and representation of knowledge.

Landauer, Thomas K., Dumais, Susan T.·1997·Psychological Review

Abstract

How do people know as much as they do with as little information as they get? The problem takes many forms; learning vocabulary from text is an especially dramatic and convenient case for research. A new general theory of acquired similarity and knowledge representation, latent semantic analysis (LSA), is presented and used to successfully simulate such learning and several other psycholinguistic phenomena. By inducing global knowledge indirectly from local co-occurrence data in a large body of representative text, LSA acquired knowledge about the full vocabulary of English at a comparable rate to schoolchildren. LSA uses no prior linguistic or perceptual similarity knowledge; it is based solely on a general mathematical learning method that achieves powerful inductive effects by extracting the right number of dimensions (e.g., 300) to represent objects and contexts. Relations to other theories, phenomena, and problems are sketched. Prologue "How much do we know at any time? Much more, or so I believe, than we know we know!"--Agatha Christie, The Moving Finger A typical American seventh grader knows the meaning of 10-15 words today that she did not know yesterday. She must

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Latent semantic analysis reveals the vast amount of information embodied in statistical relations between words and the larger contexts in which they occur.

    “This work reveals the vast amount of information now embodied in statistical (but deep, not fi rst order) relations between words and the larger contexts (sentences and texts) in which they occur.”

  • Corcoran et al. predicted the onset of schizophrenia by discriminating speech of healthy controls and people with early onset schizophrenia with approximately 80% accuracy.

    “They were able to successfully predict the onset of schizophrenia by discriminating the speech of healthy controls and those with early onset schizophrenia with ~ 80% accuracy.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
