TEMPORAL INFERENCES IN COMPUTATIONAL LINGUISTIC INFORMATION PROCESSING (ARTIFICIAL INTELLIGENCE, PROBLEM SOLVING, DATABASE MANAGEMENT, COGNITION, KNOWLEDGE REPRESENTATION) | Posted on:1985-04-27 | Degree:Ph.D | Type:Dissertation | University:The Ohio State University | Candidate:OBERMEIER, KLAUS KARL | Full Text:PDF | GTID:1478390017962034 | Subject:Language | Abstract/Summary: | | This dissertation aims for an integration of insights gained from linguistic, psychological and Artificial Intelligence based research to provide a pragmatic theory and mental model of how natural language processing and temporal inferences can be explained with the framework of computational information processing. A pragmatic theory focuses on the information from the context (e.g., co-text, text-type, and audience) to explain linguistic behavior. A mental model provides an internal representation of the state of affairs that are described in a given sentence.;The computer program (implemented in ELISP on EFRL on a DEC20/60) performs the following tasks: (1) parse a text from a medical journal while using linguistic and extra-linguistic knowledge; (2) map the parsed linguistic structure into an event-representation; (3) draw temporal and factual inferences within the domain of liver diseases; (4) create and update a data base containing the pertinent information about a patient.;The objectives of this research are twofold, whereby the computer program is meant to be a particular implementation of a general natural language processing system which could be used for a variety of domains. The first objective is to show how an integration of linguistic and extra-linguistic knowledge achieves a form of comprehension, where comprehension is characterized as a conversion of information based on knowledge from one representation into another. The second objective is to show that such a procedural approach is a basis for an event-based theory for temporal information processing. | Keywords/Search Tags: | Information processing, Linguistic, Temporal, Inferences, Representation | | Related items |
