The syntactic analysis of this sentence is that “she” is the subject, “tossed” is the verb, and “the ball” is the direct object. This sentence’s meaning is clear, and it fits into a natural language English speakers share. Independent and dependent clauses: Syntax also uses a ...
The unsupervised approach for syntactic analysis tries to discover the structure of the text using only raw text. In this paper we explore this approach using Grammar Inference Algorithms. Despite of still having room for improvement, our approach tries to minimize the effect of the current limitati...
This thesis pursues a modular analysis of verb-complement compounds in Mandarin Chinese. As the evidence indicates, a syntactic or lexical analysis is proposed for different types of compounds. As a result, this analysis can better accou... HL Lin 被引量: 20发表: 1998年 linguistic Typology: ...
In this case, assuming the query is a term or phrase query, full text search with lexical analysis strips out the ~ and breaks the term business~analyst in two: business OR analyst.The example above is the tilde (~), but the same principle applies to every operator....
only performed on complete terms (a term query or phrase query). Query types with incomplete terms (prefix query, wildcard query, regex query, fuzzy query) are added directly to the query tree, bypassing the analysis stage. The only transformation performed on partial query terms is lower...
Generates scanners for lexical analysis on files, C++ streams, (wide) strings, and memory such as mmap files. Indent/nodent/dedent anchors to match indentation levels to tokenize. Lazy quantifiers for POSIX regex matching, i.e. no hacks are needed to work around greedy repetitions. ...
