Improving a supervised CCG parser
… researchers to develop efficient and accurate parsers trained on articles taken from the Wall Street Journal (WSJ). We present three approaches to improving the state-of-the-art in CCG parsing. First, we test novel supertagger-parser combinations to identify the parsing models and algorithms …

Adapting and improving a shallow parser
… the Icelandic language. One of these tools is IceParser, a shallow parser, whose purpose is to annotate flat phrase structure and syntactic functions. The input to IceParser are tokenised sentences, tagged with part-of-speech (POS) tags from the Icelandic POS tagset. This tagset was revised …

PassDB : parser for password dump database
Over the years many companies and institutions have been hacked and user information stolen. When the hackers are finished using the stolen data, they dump it on the internet in so-called data dumps. The project consisted of building a system that can be used to parse passwords and emails from most …

PoEM : a parser of emotion metaphors
Although metaphor is generally recognized as an integral component of everyday language, very few computational systems capable of understanding metaphoric utterances exist today. This thesis describes one approach to the problem and presents PoEM, a prototype system which recognizes and interprets …

A corpus-trained parser for systemic-functional syntax
… used for natural language generation. The parser will use a probabilistic systemic functional syntax (Fawcett 1981, Souter 1990), which was originally employed to hand-parse the Polytechnic of Wales corpus (Fawcett and Perkins 1980, Souter 1989), a 65,000 word transcribed corpus of …

An Explainable Semantic Parser for End-User Development
… programming languages, where a tailored semantic parser can translate a natural language utterance to a formal command representation able to be processed by a computational machine. Currently, semantic parsers are typically built on the top of a learning method that defines its behaviours based …

An object-oriented parser generator for LL(1) grammars
… of Object-Oriented techniques to build both a parser and a parser generator for an LL(1) attributed grammars. When top-down parsing is being used, a node of the parse tree is expanded into several other nodes. Thinking in terms of objects, an object in the tree constructs other objects. An …

A General Purpose Semantic Parser Using FrameNet and WordNet®.
… we propose a general-purpose shallow semantic parser which utilizes a semantic network (WordNet), and a frame dataset (FrameNet). Semantic relations recognized by the parser are based on how human beings represent knowledge of the world. Parsing semantic structure allows semantic units and …

The Design and Implementation of a Prolog Parser Using Javacc
… text is LL(1) in nature and any standard LL parser generator tool can be used to parse it. However, the Prolog text that conforms to the ISO Prolog standard allows the definition of dynamic operators. Since Prolog operators can be defined at run-time, operator symbols are not present in the …

Using a symbolic language parser to Improve Markov language models
… an n-gram (Markov) model with a symbolic parser. In concert these two techniques are applied to the problem of sentence simplification. The n-gram system is comprised of a relational database backend with a frontend application that presents a homogeneous interface for both direct n-gram …

The Saga Editor: A Language-Oriented Editor Based on an Incremental Lr(1) Parser
… grammars, can be based upon an incremental LR(1) parser employing incremental analysis techniques. The resulting editor is flexible, supporting a higher-level command interface which includes structure-oriented commands involving tokens and sub-trees, while retaining common text editing commands …

The unified plausibility parser : how story-understanding systems can read stories written for humans
… and implemented in Java the Unified Plausibility Parser (UPP), a tool whose goal is to interpret complex and ungrammatical sentences and translate them to a language that Genesis can understand. UPP has access to Genesis's knowledge base, and it uses it to develop expectations about what sentence …

The use of deterministic parsers on sublanguage for machine translation
… the practicability of using Deterministic Parsers in the analysis stage of a Machine Translation system. Machine Translation, Sublanguage and parsing are described in general terms with a review of Deterministic parsing systems, pertinent to this research, being presented in detail. The …

Some aspects of error correction of programming languages
… language, and the design of an error correcting parser for the BASIC language. Two important things can be said about this thesis. First, it presents the problem of error correction in a context free language, and the existing results in the field. The concept of a context free language as a …

The Availability of Semantic and Syntactic Information and Their Use As A Structural Predictor In the Real-Time Processing of L1 and L2 Korean
… in Yoshida (2006) and Chinese in Hsu (2007), the parser in Korean is characterized in two aspects. The first aspect is whether the parser is sensitive to different types of information in on-line processing such as the semantic mismatch and the case markers. The second aspect is whether the parser …

Minimal characterization of linguistic phenomena for robust ternary expression construction
… of a third-party neural network based dependency parser (spaCy) to construct semantic parses of sentences in the form of ternary expressions as pioneered by the Start Natural Language system. Ternary expressions are a powerful representation for efficiently indexing, matching, and retrieving …

Grounded semantic parsing using captioned videos
We develop a semantic parser which is trained in a grounded setting using pairs of videos captioned with sentences. This setting is both data-efficient requiring little annotation and far more similar to the experience of children where they observe their environment and listen to speakers. The …

Extraction of Basic Noun Phrases from Natural Language Using Statistical Context-Free Grammar
… grammars SCFG and CFG. A probabilistic chart parser was developed by modifying a deterministic parallel chart parser. Extraction of simple noun-phrases with the SCFG was accomplished using this probabilistic chart parser, a dictionary containing word probabilities along with the meaning, …

Domain knowledge acquisition via language grounding
… planning in a complex virtual world and input parser generation from input format specifications. In the first application, we propose a reinforcement learning framework to jointly learn to predict precondition relations from text and to perform high-level planning guided by those relations. …
