Identifying collocations in a sentence, in order to ensure their proper processing in subsequent applications, and performing the syntactic analysis of the sentence are interrelated processes. Syntactic information is crucial for detecting collocations, and vice versa, collocational information is useful for parsing. This article describes an original approach in which collocations are identifi...

As Chinese text is written without word boundaries, effectively recognizing Chinese words is like recognizing collocations in English, substituting characters for words and words for collocations. However, existing topical models that involve collocations have a common limitation. Instead of directly assigning a topic to a collocation, they take the topic of a word within the collocation as the...

In this article we propose a rank aggregation method for the task of collocations detection. It consists of applying some well-known methods (e.g. Dice method, chi-square test, z-test and likelihood ratio) and then aggregating the resulting collocations rankings by rank distance and Borda score. These two aggregation methods are especially well suited for the task, since the results of each ind...

We present a method of the structural collocations extraction for an inflective language (Polish) based on the process divided into two phases: extraction and filtering of the pairs of wordforms reduced to baseforms and structural annotation of the extracted collocations with lexico-syntactic patterns. The parameters of the patterns are specified manually but their instances are generated and t...

Natural languages are full of word collocations that frequently co-occur and correspond to arbitrary word usages. They appear in both technical and non-technical textual corpora and often have specific significance in individual contexts. Accurately retrieving and identifying collocations from a given corpus in an unsupervised manner is imperative to understanding and automatically generating t...

The appropriate use of collocations is a challenge for second language acquisition. However, high quality and easily accessible Chinese collocation resources are not available for both teachers and students. This paper presents the design and construction of a large scale resource of Chinese collocational knowledge, and a web-based application (OCCA, Online Chinese Collocation Assistant) which ...

Collocations are notoriously difficult for non-native speakers to translate, primarily because they are opaque and can not be translated on a word by word basis. We describe a program named Champollion which, given a pair of parallel corpora in two different languages, automatically produces translations of an input list of collocations. Our goal is to provide a tool to compile bilingual lexica...

In the study of collocations and of frozen sentences (idioms, clichés, collocations, many metaphors and figurative meanings, etc.) one often encounters sets of similar forms that cannot be related by formal rules of either type: phrase structure or transformational. We present examples of such situations and we show how the formalism of finite automata can be used to represent them in a natural...

Collocation is a linguistic phenomenon that is difficult to define and harder to explain; it has been largely overlooked in the field of computational linguistics due to its difficulty. Although standard techniques exist for finding collocations, they tend to be rather noisy and suffer from sparse data problems. In this paper, we demonstrate that by utilising parsed input to concentrate on one ...

A series of different automatic query expansion techniques has been suggested in Information Retrieval. To estimate how suitable a document term is as an expansion term, the most popular of them use a measure of the frequency of the co-occurrence of this term with one or several query terms. The benefit of the use of the linguistic relations that hold between query terms is often questioned. If...
