Semantic Interpretation and the Upper-Level Ontology of WordNet
نویسنده
چکیده
This paper deals with the ontology for natural language understanding. In particular, the paper focuses on the WordNet noun ontology, proposes some additions, changes and reorganizations, and explains the rationale supporting them. These changes have been pointed out by a semantic interpreter driven by over 3000 verb predicates that use WordNet noun ontology and WordNet verb classes. The selectional restrictions in the semantic roles of the predicates are WordNet ontological categories. The main criterion for changing an ontological category has been failing to interpret some sentences. A detailed analysis of the proposed changes is presented.

Query Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
متن کاملGrounding the Ontology on the Semantic Interpretation Algorithm
Some reorganizations and modifications to the WordNet ontology are explained. These changes have been suggested by extensive testing of the ontological categories with an algorithm for semantic interpretation The algorithm is based on predicates that have been defined for WordNet verb classes. The selectional restrictions of the predicates are WordNet ontological categories.
متن کاملAutomatic Construction of Persian ICT WordNet using Princeton WordNet
WordNet is a large lexical database of English language, in which, nouns, verbs, adjectives, and adverbs are grouped into sets of cognitive synonyms (synsets). Each synset expresses a distinct concept. Synsets are interlinked by both semantic and lexical relations. WordNet is essentially used for word sense disambiguation, information retrieval, and text translation. In this paper, we propose s...
متن کاملA SUMO-based Semantic Analysis for Knowledge Extraction
The process of extracting semantic information from texts is a key issue for human language technologies. However, this semantic extraction often relies on linguistic resources that are costly to acquire. This represents an obstacle to the wide development of semantic analyzers. This paper illustrates an effort in the semantic analysis of texts based on the already available upper-level ontolog...
