  • The Great Prepotion Mystery is designed to be used as a review of prepositions in an intermediate/ advance grammar course. The vocabulary is not grades, and some students may have to use a dictionary more frequently than others. The student gets practice with preposition in three ways: by choosing an appropriate preposition in context; by selecting an appropriate in a narrowly defined situation; and by using prepositions in student- generated sentences....

  • Prepositions are a class of words that indicate relationships between nouns, pronouns and other words in a sentence. Most often they come before a noun. They never change their form, regardless of the case, gender etc. of the word they are referring to. Each definition of a preposition is followed by one or more patterns, which indicate the word order appropriate for the definition. The verbs in each pattern can be changed to other tenses.

  • We present a preliminary study on unsupervised preposition sense disambiguation (PSD), comparing different models and training techniques (EM, MAP-EM with L0 norm, Bayesian inference using Gibbs sampling). To our knowledge, this is the first attempt at unsupervised preposition sense disambiguation.

  • We present several unsupervised statistical models for the prepositional phrase attachment task that approach the accuracy of the best supervised methods for this task. Our unsupervised approach uses a heuristic based on attachment proximity and trains from raw text that is annotated with only part-of-speech tags and morphological base forms, as opposed to attachment information. It is therefore less resource-intensive and more portable than previous corpus-based algorithm proposed for this task. ...

  • Ill this paper we describe a neural network-based approach to prepositional phrase attachment disambiguation for real world texts. Although the use of semantic classes in this task seems intuitively to be adequate, methods employed to date have not used them very effectively. Causes of their poor results are discussed. Our model, which uses only classes, scores appreciably better than the other class-based methods which have been tested on the Wall Street Journal corpus. To date, the best result obtained using only classes was a score of 79.1%; we obtained an accuracy score of 86.8%. ...

  • Machine translation of locative prepositions is not straightforward, even between closely related languages. This paper discusses a system of translation of locative prepositions between English and French. The system is based on the premises that English and French do not always conceptualize objects in the same way, and that this accounts for the major differences in the ways that locative prepositions are used in these languages.

  • A problem frequently encountered in the automatic parsing of Russian texts is the correct structuring of prepositional phrases in sentences. Studies of text samples indicate that, when other criteria are absent, the syntactic governors of prepositions can be determined with a high degree of accuracy by reference to the relative position and part-ofspeech of elements in the clausal environment.

  • This paper summarizes stratificational theory, and applies its linguistic methods in a sememic analysis of English prepositions. The phenomenon of interlocking diversification is shown to be quite generally present among the prepositions. Also, the analysis of prepositions is shown to entail a partial sememic analysis of other words; it therefore provides a starting point for the sememic analysis, on stratificational principles, of the rest of the language.

  • We evaluate the effect of adding parse features to a leading model of preposition usage. Results show a significant improvement in the preposition selection task on native speaker text and a modest increment in precision and recall in an ESL error detection task. Analysis of the parser output indicates that it is robust enough in the face of noisy non-native writing to extract useful information.

  • There are some sorts of ‘Preposition + Noun’ combinations in Farsi that apparently a Prepositional Phrase almost behaves as Compound Prepositions. As they are not completely behaving as compounds, it is doubtful that the process of word formation is a morphological one. The analysis put forward by this paper proposes “incorporation” by which an No is incorporated to a Po constructing a compound preposition. In this way tagging prepositions and parsing texts in Natural Language Processing is defined in a proper manner. ...

  • Prepositional phrase attachment is a common source of ambiguity in natural language processing. We present an unsupervised corpus-based approach to prepositional phrase attachment that achieves similar performance to supervised methods. Unlike previous unsupervised approaches in which training data is obtained by heuristic extraction of unambiguous examples from a corpus, we use an iterative process to extract training data from an automatically parsed corpus.

  • A pattern in the translation of locative prepositional phrases between English and Spanish is presented. A way of exploiting this pattern is proposed in the context of a multilingual machine translation system under development. Introduction Two of the main problems in machine translation (MT) are ambiguity and lexical gaps. Ambiguity occurs when a word in the source language (SL) has more that one translation into the target language (TL). Lexical gaps occur when a word in one language can not be translated directly into another language.

A treatment of locative prepositional phrases is given, thus illustrating the generation of the situation schemata and their interpretation in situation semantics.
