“…Most labels used as queries in this task are given in plural form and are reduced to singular form for matching with the base forms. More details on the model can be found in [38,39]. Assuming that q is a term like other terms, we also call this distribution the co-occurrence distribution of q.…”

“…Pada penelitian [6], jumlah lonjakan kata kunci dideteksi dengan cara menghitung frekuensi kemunculan suatu kata kunci dengan pembobotan Term Frequency-Inverse Document Frequency (TF-IDF) dan juga algoritma n-gram. Lalu pada penelitian [7], topik dideteksi dengan menghitung probabilitas kemunculan bersama suatu kata kunci dengan metode Jensen-Shannon Divergence dan mengelompokan kata kunci tersebut dengan algoritma K-Means.…”

“…This work aims at proposing and implementing a Topic updation using Testor theory [4] model for discovering and updating meaningful and concise labels for the dynamically updated clusters which are grouped using Semantic Similarity based Histogram based Incremental Document Clustering (SHC) [5] and Enhanced Similarity Histogram Clustering using Intra Centroid Vector Similarity (ESHC-IntraCVS) [6] based on Semantic-based similarity for the scientific literature documents and newsgroup dataset. This proposed technique is compared with the existing Topic Discovery by clustering keywords [7] proposed by Wartena and Brussee, (2008) and TF-IDF classifier [8] by Seymore and Rosenfeld (1997) method using F-measure and Purity as evaluation metrics.…”
