This study examined neurofunctional correlates of reading by modulating semantic, lexical, and orthographic attributes of letter strings.
(alpha ) is the weight attributed to lexical similarity, (beta ) is the weight attributed to semantic similarity, (gamma ) is the weight attributed to syntactico-semantic similarity and.
The classification equation defined by SMO function is presented as follows: begin{aligned} mathrm{Sim (S1, S2)}= alpha *mathrm{SL}+beta *mathrm{SM}+gamma *mathrm{SSM}+C, end{aligned} (5 where (alpha ) is the weight attributed to lexical similarity, (beta ) is the weight attributed to semantic similarity, (gamma ) is the weight attributed to syntactico-semantic similarity and C is constant.
Recent work, (Santos et al., 2014), evaluated 58 features encoding the lexical context and the geospatial attributes of toponyms when performing toponym resolution.
The authorship analysis methods employed were similar to ones utilized in prior studies using supervised machine learning classifiers such as a multi-class decision tree and established stylometric identification feature sets encompassing lexical, syntactic, structural, and content-specific attributes [4] [7].
Lexical features (word-level features) include attributes of lexical items or words in the text.
It should be noted that Frege did not attribute semantic properties to lexical units as such, but to what he regarded as a sentence's logical constituents: e.g., not to the word 'dog' but to the predicate 'is a dog'.
For instance, the lexical, linguistic and structural differences must be attributed to Wikipedia editors, since they are expected to use their own words and interlink articles manually.
However, in these patients, the locus of the impairment could be attributed to a post-semantic (lexical selection) stage of processing.
The representation of the meaning can either be a lexical ontology such as WordNet (Fellbaum 1998), an attribute-based structure (Blackburn 1993), or a distributional semantic model such as word vector model (Erk 2012; Turney and Pantel 2010).
