الوصف: This paper presents L-KD, a tool that relies on available linguistic and knowledge resources to perform keyphrase clustering and labelling. The aim of L-KD is to help finding and tracing themes in English and Italian text data, represented by groups of keyphrases and associated domains. We perform an evaluation of the top-ranked domains using the 20 Newsgroup dataset, and we show that 8 domains out of 10 match with manually assigned labels. This confirms the good accuracy of this approach, which does not require supervision.
In questo lavoro descriviamo L-KD, un sistema che utilizza risorse linguistiche e basate su conoscenza per raggruppare concetti-chiave e categorizzarli. L’obiettivo di L-KD è quello di supportare gli utenti nel rilevare la presenza di specifici temi in documenti italiani e inglesi, rappresentandoli attraverso gruppi di concetti-chiave e relativi domini. Abbiamo valutato l’affidabilità del sistema analizzando i domini più rilevanti nel 20 Newsgroup dataset, e dimostrando che 8 su 10 domini nel gold standard sono assegnati correttamente anche dal sistema. Questa valutazione conferma le buone performance di L-KD, senza il bisogno di supervisione.
