We introduce two succinct data structures to solve various string problems. One is for storing the information of lcp, the longest common prefix, between suffixes in the suffix array, and the other is an improvement in the compressed suffix array which supports linear time counting queries for any pattern. The former occupies only 2n + o(n) bits for a text of length n for computing lcp between ...

The process of sorting the suffixes of a text plays a fundamental role in Text Algorithms. They are used for instance in the constructions of the BurrowsWheeler transform and the suffix array, widely used in several fields of Computer Science. For this reason, several recent researches have been devoted to finding new strategies to obtain effective methods for such a sorting. In this paper we i...

Cross-linguistically, prefixes and suffixes differ in both frequency and in phonological behavior. These differences could plausibly have their source in listeners’ subjective perceptual experiences of prefixes and suffixes, an idea that we pursued using a noise-rating task in Spanish. Participants heard minimally-different Spanish words such asme patea ‘s/he kicks me’ versus patéame ‘kick me’,...

Although a number of attempts have been made to develop a stemming formalism for the Arabic language, most of these attempts have focused merely on the lexical structure of words as modeled by the Arabic grammatical and morphological lexical rules. This paper discusses the merits of light stemming for Arabic data and presents a simple light stemming strategy that has been developed on the basis...

We present a linear time algorithm to sort all the suffixes of a string over a large alphabet of integers. The sorted order of suffixes of a string is also called suffix array, a data structure introduced by Manber and Myers that has numerous applications in computational biology. Though the suffix tree of a string can be constructed in linear time and the sorted order of suffixes derived from ...

This paper attempts to answer a threefold question: from what kind of cues gender can reliably be assigned to French nouns? How the usage of these sublexical cues is acquired by children? What kind of computational models could account for the human data? We conducted an experiment with 73 1 and 2 grade children to assess their knowledge about gender information associated with suffixes using a...

Like other Atlantic languages, Wolof has a large inventory of verbal derivation suffixes, but is exceptionally well endowed for causative with no less than eight different suffixes. This article analyzes the values these suffixes and reveals firstly double gradient distinctions concerning degrees involvement causer causee. Among two show typologically rare specialization, one being specialized ...

The present study attempts to measure and compare the morphological productivity of five Mandarin Chinese suffixes: the verbal suffix -hua, the plural suffix -men, and the nominal suffixes -r, -zi, and -tou. These suffixes are predicted to differ in their degree of productivity: -hua and -men appear to be productive, being able to systematically form a word with a variety of base words, whereas...

English spelling is unphonetic: the same sounds can be spelled in various and often idiosyncratic ways. It is also ungoverned: there is no authority guiding its development. However, it is not as arbitrary as one might conclude. Investigating the spelling of four derivational suffixes, we show that the spelling of English suffixes is quite consistent. Homophonous endings of morphologically simp...
