    "title": "Incorporating Background Knowledge into Text Classification",
    "subtitle": null,
    "abstract": "It has been shown that prior knowledge and information are\norganized according to categories, and that also background\nknowledge plays an important role in classification. The purpose\nof this study is first, to investigate the relationship between\nbackground knowledge and text classification, and second,\nto incorporate this relationship in a computational model.\nOur behavioral results demonstrate that participants with access\nto background knowledge (experts), overall performed\nsignificantly better than those without access to this knowledge\n(novices). More importantly, we show that experts rely more\non relational features than surface features, an aspect that bagof-\nwords methods fail to capture. We then propose a computational\nmodel for text classification which incorporates background\nknowledge. This model is built upon vector-based representation\nmethods and achieves significantly more accurate\nresults over other models that were tested.",
