Interpreting compound nouns with kernel methods
نویسندگان
چکیده
This paper presents a classification-based approach to noun-noun compound interpretation within the statistical learning framework of kernel methods. In this framework, the primary modelling task is to define measures of similarity between data items, formalised as kernel functions. We consider the different sources of information that are useful for understanding compounds and proceed to define kernels that compute similarity between compounds in terms of these sources. In particular, these kernels implement intuitive notions of lexical and relational similarity and can be computed using distributional information extracted from text corpora. We report performance on classification experiments with three semantic relation inventories at different levels of granularity, demonstrating in each case that combining lexical and relational information sources is beneficial and gives better performance than either source taken alone. The data used in our experiments are taken from general English text, but our methods are also applicable to other domains and potentially to other languages where noun-noun compounding is frequent and productive.

An Analysis of Persian Compound Nouns as Constructions
In Construction Morphology (CM), a compound is treated as a construction at the word level with a systematic correlation between its form and meaning, in the sense that any change in the form is accompanied by a change in the meaning. Compound words are coined by compounding templates which are called abstract schemas in CM. These abstract constructional schemas generalize over sets of existing...
متن کاملFree Paraphrases of Noun Compounds
We often come across sentences in our daily life containing many nouns which act as a compound noun. The interpretation of these noun compounds may be a very trivial task for us but it is of great value to one who is trying to understand the semantic meaning of any sentence. For a machine to understand the meaning of such compound nouns it should be able to understand the relation between the n...
متن کاملDemonyms and Compound Relational Nouns in Nominal Open IE
Extracting open relational tuples that are mediated by nouns (instead of verbs) is important since titles and entity attributes are often expressed nominally. While appositives and possessives are easy to handle, a difficult and important class of nominal extractions requires interpreting compound noun phrases (e.g., “Google CEO Larry Page”). We substantially improve the quality of Open IE from...
متن کاملLearning compound noun semantics
This thesis investigates computational approaches for analysing the semantic relations in compound nouns and other noun-noun constructions. Compound nouns in particular have received a great deal of attention in recent years due to the challenges they pose for natural language processing systems. One reason for this is that the semantic relation between the constituents of a compound is not exp...
متن کاملInterpreting Anaphoric Shell Nouns using Antecedents of Cataphoric Shell Nouns as Training Data
Interpreting anaphoric shell nouns (ASNs) such as this issue and this fact is essential to understanding virtually any substantial natural language text. One obstacle in developing methods for automatically interpreting ASNs is the lack of annotated data. We tackle this challenge by exploiting cataphoric shell nouns (CSNs) whose construction makes them particularly easy to interpret (e.g., the ...
