TEXT ANALYSIS IN NATURAL LANGUAGE PROCESSING INCLUDING PART-OF-SPEECH TAGGING, LATENT SEMANTIC ANALYSIS, AND CONTEXTUAL CONTINUITY
 
ABSTRACT:
Language serves as a vehicle for communication, and communication patterns are well documented. For example, breaks up communication into requests, information-helping, and sharing.  However, the words that make up a language are not semantics.  They are composed from an underlying symbolic alphabet,{A_i }, defined only by their presence or absence in an associated language dictionary D={W_k }. Word sense disambiguation may be viewed as a selection operation, where, given a word, we wish to pick one unique semantic interpretation for each instance of the word.  This talk will discuss a few text analysis studies in natural language processing.
