FinnWordNet is a Finnish wordnet which complies with the structure of the Princeton WordNet (Fellbaum, 1998). It was created by translating all the words in Princeton WordNet. It is open source and contains over 117 000 synsets. We are now testing different methods in order to improve and expand the content of FinnWordNet. Since wordnets are structured ontologies, a location for a word in FinnW...

stemming is the process of finding the main morpheme of a word andit is used in natural language processing, text mining and informationretrieval systems. a stemmer extracts the stem of the words. we can classifypersian stemmers in to three main classes: structural stemmers, dictionarybased stemmers and  statistical stemmers.the precision of structural stemmers is low and the expenses of dictio...

This retrospective, exploratory investigation examined the types of target words that 30 children with word-finding difficulties (aged 8 to 12 years) had difficulty naming and the types of errors they made on these words. Words were studied with reference to lexical factors that might influence naming performance: word frequency, age of acquisition, familiarity, and lexical neighborhood. Findin...

This article introduces an unsupervised word sense disambiguation algorithm that is inspired by the lexical attraction models of Yuret (1998). It is based on the assumption that the meanings of the words that form a sentence can be best assigned by constructing an interpretation of the whole sentence. This interpretation is facilitated by a dependency-like context specification of a content wor...

This paper investigates relations between word semantic density and word frequency. A distributed representations based word average similarity is defined as the measure of word semantic density. We find that the average similarities of low frequency words are always bigger than that of high frequency words, when the frequency approaches to 400 around, the average similarity tends to stable. Th...

Pseudo-repetitions are a natural generalisation of the classical notion of repetitions in sequences: they are the repeated concatenation of a word and its encoding under a certain morphism or antimorphism (anti-/morphism, for short). We approach the problem of deciding efficiently, for a word w and a literal anti-/morphism f , whether w contains an instance of a given pattern involving a variab...

An unsupervised method for word sense disambiguation is proposed. The sense of the word is chosen to be the most similar to the senses of other words that appear in the corpus in similar contexts. Training consists of building a weighted list of related words (quasi-synonyms) for each word; the weights are obtained by measuring similarity between the word’s contexts. We adapt the algorithm of M...

We tested theories of eye movement control in reading by looking at parafoveal processing. According to attention-processing theories, attention shifts towards word n + 1 only when processing of the fixated word n is finished, so that attended parafoveal processing does not start until the programming of the saccade programming to word n + 1 is initiated (Henderson & Ferreira, 1990; Morrison, 1...

this study attempts to measure online search skills among graduate students of shiraz university and to determine their ability in using them. according to the previous studies and available sources in this field, seven online search skills which were the most useable ones and also current skills were selected for this study. also 10 factors which affect these skills were determined. this study...
