Sentences sentence splitting

Sentence splitting segmentation of the document into a list of sentences. 

Now that we know what we are looking for (underlying words) we can turn our attention to the problem of how to extract these from text. While in principle this could be achieved in a single process, it is common in TTS to perform this in a number of steps. In this section and the next we deal with the initial steps of tokenisation and sentence splitting which aim to split the input sequence of characters into units which are more easily processed by other processes which attempt to determine the word identity, subsequent... 

Many of the algorithms in TTS work a sentence at a time. This is because most linguistic units smaller than this (words, syllables) etc are heavily influenced by their neighbours which makes autonomous processing difficult. Sentences on the other hand don t interact with each other much, and apart from some specific phenomena, we can by and large process each sentence independently without problem. The input to the TTS system is not necessarily in sentence form however, and in many cases we are presented with a document which contains several sentences. The task of sentence splitting then is to take the raw document and segment it into a list of sentences. 

While sentence splitting is not the most complex of tasks in TTS, it is important to get right and this is mainly due to the fact that sentence-final prosody is one of the phenomena that listeners are most sensitive to. Generating the high quality sentence-final prosody is hard enough in its own right, but if the sentence boundary is in the wrong place, then the system has no chance. 

A basic sentence splitting algorithm for conventional writing can be defined as follows ... 

This tag can be used to override the decisions of the sentence splitting algorithm. 

This tag indicates that a sentence break should be placed at this point. It is a good way for the author to override any possible shortcomings in the sentence-splitting algorithm. 

I do not go out of my way to boldly split infinitives, nor do I actively seek prepositions to end sentences with. Yet by these constructions alone, I may be viewed by some as aiding the decline in students ability to communicate. 

Some infinitives seem to improve on being split, just as a stick of round stovewood does. I cannot bring myself to really like the fellow. The sentence is relaxed, the meaning is clear, the violation is harmless and scarcely perceptible. Put the other way, the sentence becomes stiff, needlessly formal. A matter of ear. 

Identify the split infinitives in the following sentences. Rewrite each sentence without a split infinitive, unless the change will create unwanted ambiguity. 

Consider the sentences below. Does the split infinitive prevent awkwardness and/ or ambiguity If so, indicate leave as is. If not, indicate rewrite without a split infinitive. ... 

Jennifer was a good student and a member of the school marching band and drama club. Her friend Dave asked her to hold onto a bag that he had. The bag was sealed, so she didn t know what was in it. As she was walking down the hallway in school, the bag fell and split open, spilling out a bunch of pills that turned out to be barbiturates. Jennifer didn t know what they were or why Dave had them, but it didn t matter to her school, the police, or the judge in court. Jennifer was not sentenced to jail, but she had to pay a 10,000 fine for possession of illegal drugs. 

Split infinitives are acceptable in some types of writing, but they should be avoided in technical reports. A split infinitive bothers many readers, and it frequently results in misplaced emphasis. Instead of The supervisor intended to carefully check the data, the sentence should be The supervisor intended to check the data carefully. ... 

Most TTS systems have adopted a solution whereby a single data structure is passed between each module. Usually, this data structure represents a single sentence, so the TTS system works by first splitting the input into sentences by the sentence splitter, forming a data structure containing... 

The first parameter can be considered to be the input parameter, the second to be the output parameter. The first parameter is a list of words, which is split into two sublists. The first sublist, the words at the beginning of the sentence, is parsed by the rule. The second sublist forms the second parameter. It consists of the remaining words of the sentence that are not parsed by the rule.
