Text classification is one of the most important tasks in Natural Language Processing. It is the process of classifying text strings or documents into different categories, depending upon the contents of the strings.

The grammatical function or meaning of a sentence is dependent on this structural organization, which is also called syntax or syntactic structure. In traditional grammar, the four basic types of sentence structures are the simple sentence, the compound sentence, the complex sentence, and the compound-complex sentence. When reading a sentence, we generally expect the first noun to be the subject and the second noun to be the object.

This expectation which isn't always fulfilled is known in linguistics as the " canonical sentence strategy. One of the first lessons learned by the student of language or linguistics is that there is more to language than a simple vocabulary list. To learn a language, we must also learn its principles of sentence structure, and a linguist who is studying a language will generally be more interested in the structural principles than in the vocabulary per se. The subject is a word or a group of words that functions as a noun; the predicate is at least a verb and possibly includes objects and modifiers of the verb.

At the same time, sentence structure is a central aspect of every sentence. We can appreciate the importance of sentence structure by looking at examples within a single language. For instance, in English, the same set of words can convey different meanings if they are arranged in different ways. Consider the following:. The meaning of [first] the sentence is quite different from that of [the second], even though the only difference is the position of the words objected to and proposed.

Although both sentences contain exactly the same words, the words are structurally related to each other differently; it is those differences in structure that account for the difference in meaning. This communicative principle may be put to good use in the analysis of sentence structure by taking the boundary between old and new information as a clue to identifying a syntactic boundary.

In fact, a typical SVO sentence such as Sue has a boyfriend can be broken down into the subject, which codes the given information, and the remainder of the sentence, which provides the new information. Humans have a unique capacity to go very rapidly through the complex hierarchically organized processes involved in speech production and perception.

When syntacticians draw structure on sentences they are adopting a convenient and appropriate shorthand for these processes. A linguist's account of the structure of a sentence is an abstract summary of a series of overlapping snapshots of what is common to the processes of producing and interpreting the sentence. This means that the study of language belongs to the scientific tradition of using experiments to understand some part of our world.

For example, if we make up a sentence 1 and then make a small change to it to get 2 , we find that the second sentence is ungrammatical. Grammatically correct. Grammatically incorrect. One possibility is that it relates to the words themselves; perhaps the word white and the word house must always come in this order.

But if we were to explain in this way we would need separate explanations for a very large number of words, including the words in the sentences 3 - 6 , which show the same pattern. The words white, new , and hungry are all a class of word called an adjective ; the words house, book , and dogs are all a class of word called a noun. We could formulate a generalization, which holds true for the sentences in 1 - 6 :.

One of the useful consequences of a generalization is to make a prediction which can then be tested, and if this prediction turns out to be wrong, then the generalization can be improved. The generalization in 7 makes a prediction which turns out to be wrong when we look at sentence 8. Share Flipboard Email. Richard Nordquist. English and Rhetoric Professor.

English Language Sentence Structure

In virtually every decision they make, executives today consider some kind of forecast. Sound predictions of demands and trends are no longer luxury items, but a necessity, if managers are to cope with seasonality, sudden changes in demand levels, price-cutting maneuvers of the competition, strikes, and large swings of the economy. Forecasting can help them […]. Forecasting can help them deal with these troubles; but it can help them more, the more they know about the general principles of forecasting, what it can and cannot do for them currently, and which techniques are suited to their needs of the moment. Here the authors try to explain the potential of forecasting to managers, focusing special attention on sales forecasting for products of Corning Glass Works as these have matured through the product life cycle. Also included is a rundown of forecasting techniques. To handle the increasing variety and complexity of managerial forecasting problems, many forecasting techniques have been developed in recent years.

A deep learning classifier for sentence classification in biomedical and computer science abstracts

The grammatical function or meaning of a sentence is dependent on this structural organization, which is also called syntax or syntactic structure. In traditional grammar, the four basic types of sentence structures are the simple sentence, the compound sentence, the complex sentence, and the compound-complex sentence. When reading a sentence, we generally expect the first noun to be the subject and the second noun to be the object.

This paper presents an experimental study that provides evidence for the existence of two types of rising declaratives in English which differ systematically in their forms and their functions. The two are labelled assertive rising declaratives and inquisitive rising declaratives, respectively. Guided by the experimental results, the paper develops a semantic analysis of them. Having as backdrop an extended Lewisian model of discourse involving a conversational scoreboard, the analysis associates assertive and inquisitive rising declaratives with distinct sets of context-changing conventions that bring about fundamentally different updates to core elements of the context. In the process, it highlights their respective partial overlaps with the conventions for two other sentence types, falling declaratives and polar interrogatives.

There are two forms of data analysis that can be used for extracting models describing important classes or to predict future data trends.

Metrics details. Given a set of pre-defined medical categories used in Evidence Based Medicine, we aim to automatically annotate sentences in medical abstracts with these labels. We constructed a corpus of 1, medical abstracts annotated by hand with specified medical categories e. Intervention , Outcome.

The automatic classification of abstract sentences into its main elements background, objectives, methods, results, conclusions is a key tool to support scientific database querying, to summarize relevant literature works and to assist in the writing of new abstracts.
