IceParser: An Incremental Finite-State Parser for Icelandic
نویسندگان
چکیده
We describe and evaluate an incremental finite-state parser for Icelandic – the first parser published for the language. Input to the parser is POS tagged text and it generates output according to a shallow syntactic annotation scheme, specifically designed for this project. The parser consists of a phrase structure module and a syntactic functions module. Both modules comprise a sequence of finite-state transducers, each of which adds syntactic information into substrings of the input text. F-measure for constituents and syntactic functions is 96.7% and 84.3%, respectively. These results are good, because Icelandic has a relatively free word order which can be difficult to account for in a parser. Moreover, of the various morphological features available in the rich POS tags, the transducers only use the case feature in their patterns.

IceNLP: a natural language processing toolkit for icelandic
Icelandic is a morphologically complex language, for which language technology resources are scarce. Only a few years ago, it could be stated that language technology was practically non-existent in Iceland. In this paper, we describe the development of an NLP toolkit for processing the language, the challenges faced and the decisions made during development. The current version of the toolkit ...
متن کاملIncremental Partial Parser of Unrestricted Natural Language Sentences
One of the current focuses of research within natural language processing is the partial and robust parsing of sentences written in natural language. Partial parsing could be used in diverse applications as data extraction, machine translation, dialogue systems, etc. His main attractiveness is that is able to handle unrestricted sentences, that contain lexical errors or that present constructio...
متن کاملLexicalized Semi-incremental Dependency Parsing
Even leaving aside concerns of cognitive plausibility, incremental parsing is appealing for applications such as speech recognition and machine translation because it could allow for incorporating syntactic features into the decoding process without blowing up the search space. Yet, incremental parsing is often associated with greedy parsing decisions and intolerable loss of accuracy. Would the...

Two-point incremental forming method is considered a modern technique for manufacturing shell parts. The presence of bottom punch during the process makes this technique far more complex than its conventional counterpart i.e. single-point incremental forming method. Thus, the numerical simulation of this method is an essential task, which leads to the reduction of trial/error costs, predicts th...

This paper provides an incremental layerwise finite element formulation for the viscoelastic analysis of multilayered pavements. The constitutive behavior of asphalt concrete is represented by the Prony series. Layerwise finite element has been shown to provide an efficient and accurate tool for the numerical simulation of laminated structures. Most of the previous research on numerical simula...
