Interactive Semantic Analysis of Technical Texts
نویسندگان
چکیده
Sentence syntax is the basis for organizing semantic relations in TANKA, a project that aims to acquire knowledge from technical text. Other hallmarks include an absence of precoded domain-specific knowledge; significant use of public-domain generic linguistic information sources; involvement of the user as a judge and source of expertise; and learning from the meaning representations produced during processing. These elements shape the realization of the TANKA project: implementing a trainable text processing system to propose correct semantic interpretations to the user. A three-level model of sentence semantics including a comprehensive Case system provides the framework for TANKA’s representations. Text is first processed by the DIPETT parser, which can handle a wide variety of unedited sentences. The semantic analysis module HAIKU then semi-automatically extracts semantic patterns from the parse trees and composes them into domain knowledge representations. HAIKU’s dictionaries and main algorithm are described with the aid of examples and traces of user interaction. Encouraging experimental results are described and evaluated.

Translating a detailed linguistic semantic representation into Horn clause logic
From the semantic representation produced by TANKA, a domain-independent, knowledge-scant, and interactive natural language analyzer, we construct Horn clauses which represent the facts or rules found in technical texts, specifically legal texts. This article describes the conversion process and the way it takes into account the detailed structure returned by the analyzer, a precise syntacticse...
متن کاملContrastive Analysis of Metadiscourse Markers Used by Non-native (Iranians) vs. Native (Americans) Speakers in Developing ELT Materials
Metadiscourse is a widely used term in current discourse analysis and language education, referring to an interesting, and relatively new approach to conceptualizing interaction between text producers and their texts and between text producers and users. Despite the growing importance of the term, however, it is often understood in different ways and used to refer to different aspects of langua...

متن کاملThe Impact of Semantic Mapping Instruction on Iranian EFL Learners’ Reading Comprehension of Expository Texts
The current article was an attempt to investigate the effect of semantic mapping strategy instruction on reading comprehension performance of EFL learners. To this end, thirty homogeneous Iranian intermediate EFL learners attending a language school in Bonab, Iran, were randomly assigned to two groups, one as the experimental and the other as the control. The experimental group received instruc...
متن کاملMetadiscourse Markers Revisited in EFL Context: The Case of Iranian Academic Learners’ Perception of Written Texts
Moving in line with the postulation that metadiscourse (MD) markers help transform a dry and tortuous piece of text into a coherent and reader-friendly one, the researchers in the current study attempted to investigate the effect different metadiscourse markers might have on Iranian EFL learners’ perception of written texts. To this end, 120 undergraduate English students were given three diffe...
متن کاملAn Overview of LSA-Based Systems for Supporting Learning and Teaching
Latent Semantic Analysis (LSA, [1]) is a well-known technique that captures semantic information in texts by uncovering word-usage regularities. Extensive research on LSA has proven its efficiency in the domain of natural language processing, and more specifically for computer-based instruction—tutoring systems, interactive learning environments [2]. The power of LSA lies in its versatility, re...
