Tokenization is the first stage in the classification pipeline; it involves breaking the text stream into tokens ("terms"), usually by means of a regular expression.
Initially, we simplify the text by removing some tokens (the Remove Tokens step).
He explained second factors as "everything from finger scanner, eye scanner, smart card, security token, text message, they're all second factor solutions that work after your password.
Running this tagger against the non-tagged text gives the following (tokens denoted by single box, OSCAR-tagged tokens are in double boxes, regex-tagged tokens are underlined and English POS-tagged tokens are in italics) (Figure 4): Figure 4 English POS Tagging.
In actual running text, the first two tokens would be written sente-se but here were split into two.
OSCAR3 employs a naïve Bayesian model to identify "chemical" tokens in text and offers a choice of two methods for the identification of multi-token named entities.
We attempt to capture this property by matching tokens in text against lists of commonly used chemical prefixes and suffixes whose lengths range from two to four.
Token Basic segments No. of basic segments 10-acetoxyactinidine 10, acet, oxy, actin, idine 5 methylergonovine methyl, ergo, novi, ne 4 interleukin-2 interleukin, 2 2. In order to account for chemical element symbols, which are not always covered by our five chosen dictionaries, we matched tokens in text against a list of symbols which occur in the periodic table of elements.
The researchers analyzed the efficiency of the factory reset implementation in 21 second-hand phones running Android versions between 2.3 and 4.3 and found that they could recover emails, text messages, Google access tokens and other sensitive data.
