N-grams have been widely investigated for a number of text processing tasks. However n-gram based systems often labor under the large memory requirements of naïve storage of the large vectors that describe the many n-grams that could potentially appear in documents. This problem becomes more severe as the number of documents (and hence the number of vectors to store and process) rises. A natura...

Our proposal, identifying sentiments in N -grams (ISN), focuses on both word order and phrases, and the interdependency between specific ratings and corresponding sentiments in texts to detect subjective information.

A procedure is described for the isolation of native DNA from protoplasts of ammi (Ammi visnaga) and carrot (Daucus carota) cells. Protoplasts were produced from 40 grams of fresh cells by enzyme hydrolysis and lysed with sodium dodecyl sulfate. The DNA was purified by treatment with pronase and ribonuclease. Final isolation was achieved by sucrose density gradient centrifugation.The melting te...

Data sparsity is a large problem in natural language processing that refers to the fact that language is a system of rare events, so varied and complex, that even using an extremely large corpus, we can never accurately model all possible strings of words. This paper examines the use of skip-grams (a technique where by n-grams are still stored to model language, but they allow for tokens to be ...

A popular and well-studied class of filters for approximate string matching compares substrings of length q, the q-grams, in the pattern and the text to identify text areas that contain potential matches. A generalization of the method that uses gapped q-grams instead of contiguous substrings is mentioned a few times in literature but has never been analyzed in any depth. In this paper, we repo...

INTRODUCTION To investigate and highlight the effect of formaldehyde induced weight reduction in transurethral resection of prostate (TURP) and radical robotically-assisted prostatectomy (RALP) specimen as a result of standard chemical fixation. MATERIALS AND METHODS 51 patients were recruited from January 2013 to June 2013 who either underwent a TURP (n=26) or RALP (n=25). Data was collected...

In this work we investigate the usefulness of n-grams for document indexing in text categorization (TC). We call n-gram a set tk of n word stems, and we say that tk occurs in a document dj when a sequence of words appears in dj that, after stop word removal and stemming, consists exactly of the n stems in tk, in some order. Previous researches have investigated the use of n-grams (or some varia...

21 kilometres north of Stewart (Figure 2-IZ-l), on the east The Silbak Premier mine is in northwest British Columbia, side of the Salmon River Valley. The original discovery of a that from 1918 to 1953 produced 4.3 million tonnes of ore high-grade vein in 1910 culminated in an underground mine grading 14.6 grams gold and 304 grams silver per tonne from sulphide-bearing stockworkveins and brecci...
