    "title": "Document Similarity Misjudgment by LSA: Misses vs. False Positives",
    "subtitle": null,
    "abstract": "Modeling text document similarity is an important yet\nchallenging task. Even the most advanced computational\nlinguistic models often misjudge document similarity relative\nto humans. Regarding the pattern of misjudgment between\nmodels and humans, Lee and colleagues (2005) suggested that\nthe models’ primary failure is occasional underestimation of\nstrong similarity between documents. According to this\nsuggestion, there should be more extreme misses (i.e., models\nfailing to pick up on strong document similarity) than extreme\nfalse positives (i.e., models falsely detecting document\nsimilarity that does not exist). We tested this claim by\ncomparing document similarity ratings generated by humans\nand latent semantic analysis (LSA). Notably, we implemented\nLSA with 441 unique parameter settings, determined optimal\nparameters that yielded high correlations with human ratings,\nand finally identified misses and false positives under the\noptimal parameter settings. The results showed that, as Lee et\nal. predicted, large errors were predominantly misses rather\nthan false positives. Potential causes of the misses and false\npositives are discussed.",
