Towards Dark Jargon Interpretation in Underground Forums

JargonFM: A Framework with Multiple Interpretation Modes for Jargon Understanding in Online Communities

“…For each word in a text, if the word's thematic coherence to the text is lower than a given threshold, the word will be seen as jargon. [3]- [5] calculate each word's occurrence probability on both jargon corpus and regular corpus, and then utilize the difference to determine whether the word is jargon. Some research attempts to conduct jargon detection using implicit features.…”

“…On the one hand, some research attempts to elaborate the meaning of jargon words in a human-readable form. For example, [3] obtains the word vector of each word in the corpus, then utilizes the KL-Divergence and crosscontext lexical analysis (CCLA) to map jargon to ordinary words. Finally, authors could interpret jargon by these common words.…”

For example, [4] explained each jargon word by finding its hypernym and hyponym based on deep learning techniques, [1] proposed a method that could link the jargon word to be explained with the known jargon words, and [3], [5] explained jargon by utilizing lexical context. As exploratory studies, these methods are proposed for specific domains or specific categories of jargon, such as underground forums, illegal trades, and specific subcultures.…”
