Recent work shows that word segmentation is influenced by distal prosodic characteristics of the input several syllables from the segmentation point (Dilley & McAuley, 2008). Here, participants heard eight-syllable sequences with a lexically ambiguous four-syllable ending (e.g., crisis turnip vs. cry sister nip). The prosodic characteristics of the initial five syllables were resynthesized in a...

The present study investigates the relevance of fundamental frequency in speech segmentation models intended to simulate infants. Speech from three different conditions (infant-directed speech to 3and 12-month-olds, and adult-directed speech) was segmented based on fundamental frequency information, using a variant of the dpn-gram segmenting technique (highlighting similar segments as lexical c...

The fact that Japanese employs scriptio continua, or a writing system without spaces, complicates the first step of an NLP pipeline. Word segmentation is widely used in Japanese language processing, and lexical knowledge is crucial for reliable identification of words in text. Although external lexical resources like Wikipedia are potentially useful, segmentation mismatch prevents them from bei...

In this paper we lay out the background of an experiment that we have not yet had time to run. The experiment will investigate the role of the Swedish word accents in the segmentation of speech for lexical access.

TextTiling is a technique for subdividing texts into multi-paragraph units that represent passages, or subtopics. The discourse cues for identifying major subtopic shifts are patterns of lexical co-occurrence and distribution. The algorithm is fully implemented and is shown to produce segmentation that corresponds well to human judgments of the subtopic boundaries of 12 texts. Multi-paragraph s...

Computational models of infant word segmentation have not been tested on a wide range of languages. This paper applies a phonotactic segmentation model to Korean. In contrast to the undersegmentation pattern previously found in English and Russian, the model exhibited more oversegmentation errors and more errors overall. Despite the high error rate, analysis suggested that lexical acquisition m...

This paper presents an overview of different approaches to melody segmentation aimed at extracting music lexical units, which can be used as content descriptors of music documents. Four approaches have been implemented and compared on a test collection of real documents and queries, showing their impact on index term size and on retrieval effectiveness. From the results, simple but extensive ap...

This paper proposes a new method of Chinese word segmentation based on proportional analogy and majority voting. First, we introduce an analogy-based method for solving the word segmentation problem. Second, we show how to use majority voting to make the decision on where to segment. The preliminary results show that this approach compares well with other segmenters reported in previous studies...

We present in this paper a method for achieving in an integrated way two tasks of topic analysis: segmentation and link detection. This method combines word repetition and the lexical cohesion stated by a collocation network to compensate for the respective weaknesses of the two approaches. We report an evaluation of our method for segmentation on two corpora, one in French and one in English, ...
