Unsupervised clustering of spontaneous speech documents
نویسندگان
چکیده
This paper presents an unsupervised method for clustering spontaneous speech documents. The approach uses a hierarchical algorithm to automatically determine the number of clusters and a starting model for a subsequent iterative algorithm. We have evaluated this method on the Switchboard corpus and compared it to a set of supervised and other unsupervised methods. The results show that our method significantly outperforms the rest of the approaches.

Data mining, also known as knowledge discovery in database, is the process to discover unknown knowledge from a large amount of data. Text mining is to apply data mining techniques to extract knowledge from unstructured text. Text clustering is one of important techniques of text mining, which is the unsupervised classification of similar documents into different groups. The most important step...
متن کاملUnsupervised Non-topical Classification of Documents
We describe the problem of non-topical clustering of documents, the purpose of which is to divide a set of documents into clusters that share some aspect. We present experiments on the British National Corpus that cluster documents by genre. We show that words are superior to part of speech information for genre clustering, but that better results can be obtained by using both. We also demonstr...
متن کاملFurther Applications of Sector-Based Detection and Short-Term Clustering
This paper presents an effective implementation of detection-localization of multiple speech sources with microphone arrays. In particular, the Scaled Conjugate Gradient descent is used for fast and precise localization, within a pre-detected volume of space, and a close to realtime implementation is provided. An unsupervised approach to speech/non-speech discrimination is also proposed. The in...
متن کاملUnsupervised Hidden Markov Modeling of Spoken Queries for Spoken Term Detection without Speech Recognition
We propose an unsupervised technique to model the spoken query using hidden Markov model (HMM) for spoken term detection without speech recognition. By unsupervised segmentation, clustering and training, a set of HMMs, referred to as acoustic segment HMMs (ASHMMs), is generated from the spoken archive to model the signal variations and frame trajectories. An unsupervised technique is also desig...
متن کاملHigh-Dimensional Unsupervised Active Learning Method
In this work, a hierarchical ensemble of projected clustering algorithm for high-dimensional data is proposed. The basic concept of the algorithm is based on the active learning method (ALM) which is a fuzzy learning scheme, inspired by some behavioral features of human brain functionality. High-dimensional unsupervised active learning method (HUALM) is a clustering algorithm which blurs the da...
